France is located in Western Europe and holding one of the largest atomic energy productions in the universe. The rapid development of atomic workss was caused by the oil daze in 1976, and the determination of the Gallic authorities to alter the energy scheme. Nuclear electricity production was developed in order to accomplish energy dependence. In add-on, atomic energy has more benefits than fossil fuel such as low CO2 nursery gas emanations, less monetary value fluctuation and more militias.
New atomic energy policies have been established about waste direction, environmental impact and transparence of public information. In the hereafter, the atomic power will still go on ruling the whole electricity coevals industries in France. The new reactor EPR developed by France and Germany is already in building. This device will likely replace the existent reactors. Other atomic engineerings are presently designed in order to accomplish the sustainability. New waste direction will be needed: the separation and incineration of the minor actinoids is one of the biggest challenges. Furthermore, new possible application might be developed to fulfill the energy demand in other Fieldss such as H production or really hot H2O production. The merger procedure is besides experienced with the ITER Project constructed in the South of France. However all these experiments need to be tested in existent conditions, and will necessitate long old ages of research.

With a turning universe energy demand and under the force per unit areas of environmental issues of firing fossil fuel, research of sustainable and renewable energy production have became a major issue for the following century.
France is one the states which generate most of electricity with atomic energy. This pick is evidently non renewable, and for the minute non sustainable. However, France has one of the cheapest and cleanest electricity productions in the universe -nuclear waste set aside. But the installings are aging. New engineerings are so necessary to replace them. These inquiries of the Gallic background in atomic, the Gallic energy policy -past and hereafter, and the R & A ; D for the new installings will be discussed farther in this study from the literature stuffs.
The end of this study is to look into and critically analyze the hereafter development of atomic energy in France. This includes the treatment about the energy demand in France, policy, resource and the engineering of atomic power. An overview of the existent state of affairs will be done. Then, the chief Gallic atomic research undertakings will be presented with their strengths and failings. Recommendations will non be given, because the determinations have already been taken by the Gallic authorities, and most of the undertakings are still in an early phase of research. This leads to a deficiency of feedback and a trouble to measure the potency of each engineering – one against each others. The state of affairs will likely germinate in the following decennary.
France is located in Western Europe and has a figure of districts in other parts such as North America, Pacific Ocean countries and etc. In this study, the treatment will chiefly concentrate on the Metropolitan Areas in Western Europe excepting those districts. France covers 547,030 km2 which is the biggest state in Europe. It is situated between 41o and 51o North and has estimated population of 65.4 million people. This state relies to a great extent on atomic power: 78.5 % of their electricity coevals is from atomic energy in 2005 [ 1 ] . Furthermore, France has the 2nd highest atomic electricity coevals in the universe – 430.9 TWh in 2005, behind the USA – 780.5TWh. It has besides the 2nd most figure of reactors in the universe – 59 reactors. The map below shows the locations of these reactors.

History and Actual state of affairs of the Gallic atomic energy
Gallic CO2 emanations, economic growing and energy ingestion
CO2 emanations, energy ingestion from 1940 to 2000
France is one of the European economic systems with the biggest addition in energy ingestion between 1960 and 2000. The most important events in this period are the oil dazes in the early 1970s. These crises earnestly affected the Gallic economic system. After a period of recovery, the Gallic energy policy has been restructured by the authorities. Significant alterations of their policy have been made, as the decrease of its over-reliance on crude oil supplies and the focal point on other energy resources. Since the French crude oil supplies were chiefly imported from other states, this policy was taking for their energy independency. Furthermore, Carbon revenue enhancements have been proposed and increase during this period. In add-on, France is committed to cut down its CO2 emanations back to the degree in 1990 under the 1997 Kyoto Protocol. The changed policy, extra C revenue enhancements and the decrease of C emanations committedness are the chief grounds for a fast growth development of atomic plans for electricity coevals.
Since 1979, CO2 emanations per capita have been worsening in France [ 3 ] . From the statistic consequences done by James, he stated that “ between 1980 and 2000, France ‘s per capita CO2 emanations declined at an mean one-year rate of 1.5 % . ” This great diminution was chiefly due to an increasing utilizations of natural gas and atomic power. In 2000, France contributed to merely 1.6 % of the universe ‘s entire CO2 emanations for 0.96 % of the universe population. And this statistic is really the lowest among the other developed states in Western Europe.
Economic growing and energy ingestions in France
Between 1960 and 2000, France had an tremendous addition of its energy ingestion. Figure 2 shows the fluctuation of the Gallic energy ingestion together with the development of CO2 emanations.
Figure 2. ( a ) per capita CO2 emanations, ( B ) per capita energy ingestion, ( degree Celsius ) per capita existent GDP, ( vitamin D ) the relation between per capita CO2 emanations and per capita existent GPD [ 3 ]
Graph B and c show the per capital GPD and energy ingestion addition at the same clip. This indicates that at this clip greater GDP – or development of the state – have been increased through a growing of the energy ingestion. From the graph B, the oil crisis in 1970 stopped merely briefly the addition of energy ingestion. However, the graph show the CO2 emanations per capita grow and have some fluctuation from 1970 to 1980 so bit by bit declines from 1980. This fluctuation might be caused by the oil crisis in 1970 and the changing of energy policy in France. As the atomic engineering become mature and the figure of atomic workss constructed raised, the trust of CO2 dropped significantly.
In 1973, the Gallic authorities changed their energy schemes from fossil fuel to atomic power for electricity in order to accomplish energy independence. Many works buildings started during the undermentioned old ages. The atomic capacity expanded significantly from 1980 to 1995. And now about 80 % of France ‘s electricity is generated by their atomic workss across the state.
In 1999 [ 4 ] , the Gallic parliamentary argument reaffirmed three chief points for the hereafter French energy policy: security of supply – since France import most of their energy resource such as Uranium, regard of the environment ( particularly CO2 and other nursery gases ) and betterment of their radioactive waste direction. Despite some attempts, there was no manner renewable and energy preservation steps could replace atomic energy in the hereafter.
Early on in 2003 [ 5 ] France ‘s first national energy argument began. This was a response to a “ strong demand from the Gallic people ” . They were experiencing ill informed. For case 58 % of them thought that atomic power caused climate alteration while merely 46 % thought that coal combustion did so. The argument was to fix the energy policy and mix for the following 30 old ages in the context of sustainable development at a European and at a planetary degree.
4 ends were defined:
1. Security of supply
2. Competitive monetary value
3. Environment and clime alteration
4. Universal entree
4 levers were given to make the ends:
better electricity and gas conveyance and or storage ”
Transparency and atomic safety jurisprudence was adopted in 2006. The guidelines were rigorous. The atomic energy ‘s development demand to hold an independent administrative authorization for safety. The relevant stakeholders should be informed of the hazards and the benefits of the engineering. Public information should be improved for handiness and transparence including the impact on the public wellness, safety and environment.
Protests have happened already in the early 70s, since the atomic plan has been promoted and encouraged by the authorities.
Harmonizing to Claude Mandil, the General Director for Energy and Raw Materials at the Ministry of Industry, Gallic people could accept atomic power for 3 chief grounds. These grounds are non valid for the other European states. First, Gallic people want to be energy independent. In fact before 1975 their energy monetary value was controlled by some volatile states such as the Middle East. Nuclear power provides cheaper and comparatively stable monetary values. This has been ever considered as strength by local citizens. Particularly during the oil daze in 1970, Gallic people were disturbed by the fluctuation of oil monetary value and the deficit of supply. After that, many Gallic people so rapidly accepted atomic power. A slogan “ no oil, no gas, no coal, no pick ” become really popular in France.
The 2nd ground is the Gallic civilization. France constructed many big high technological undertakings. This comes from the great regard for Engineer and scientist in the Gallic civilization. Gallic people tend to develop their state by accomplishing higher engineering degree. So, atomic undertaking was portion of this engineering development. In add-on, since the applied scientists and scientists callings are favored by Gallic people, Engineers and scientist have better chances to go high superior authorities functionaries. This leads to a better fiscal and political support for these big technological undertakings from the authorities.
Third, big sum of information on atomic power – including its benefits and hazard – are clearly promoted in the Gallic society by many Gallic authorizes. Nuclear power and its possibility of high sum electricity coevals are advertised on telecastings and other media such as newspaper and wireless. Many Tourss are started to allow people see and cognize about the atomic workss. Over six million Gallic people have taken up the circuit.
France has merely really few natural energy resources. “ It has no oil, no gas and her coal resources are really hapless and virtually exhausted. “ ( Palfreman )
There are chiefly three classs of energy beginnings: dodo fuels, renewable beginnings, and atomic beginnings [ 6 ] . Compared to other energy beginning, atomic energy has many benefits. Balat [ 1 ] suggested benefits includes
“ 1. It has no atmospheric emanations or pollution ( or near to none ) .
2. It is compact.
3. It produces really small waste, and this is confined and self-degradable.
4. It avoids increasing the nursery consequence [ 7 ] ”
The atomic fuel ( U ) resources have militias among many states around the universe. Uranium can be found from many stones and in saltwater. Nature Uranium needs to be refined to more concentrated resource. However, this distributed resource gives sufficient handiness and convenience to states. Russia, Canada, Australia and Niger were the largest providers of atomic stuffs to the EU, providing more than 75 % of the entire demands in 2007
The figure from Balat [ 1 ] shows a Uranium monetary value in 2007 around US $ 23 per kg. Furthermore, universe militias are about 1.2 million dozenss of recoverable Uranium with a cost of US $ 40 per kg and about 2.5 million dozenss of US $ 80 per kilogram Balat besides stated that presuming the one-year ingestion of Uranium over the universes between 60,000 and 80,000 dozenss, the US $ 80 recoverable Uranium can run into the addendum of Uranium for the future 40 old ages
The entire militias of the Uranium is adequate for the following 100 old ages [ 8 ] . The monetary value of Uranium is comparatively stable. But even in the worst instance, where Uranium go a really competitory resource and with a monetary value turning u to $ 1000/kg ; Uranium power coevals will still be really economic. In fact, the fuel represents merely 14 % of the electricity monetary value. The cost and the environmental issues of firing fossil fuel is traveling to be far greater than atomic. [ 9 ]
France is besides the state which exports the largest sum of its electricity to other states. Over the last decennary France has exported 60-80 billion kWh cyberspace each twelvemonth and the Gallic electricity company expects exports to go on at 65-70 TWh/yr, to Belgium, Germany, Italy, Spain, Switzerland and UK. Imports are comparatively fiddling.
Although atomic energy nowadayss many advantages, legion failings could be discussed. Economic necessity, runing safety, waste disposal and proliferation hazard are the major hazards of the atomic energy.
The atomic reactors have truly high potency to do tremendous amendss to the environment. The Chernobyl accident has shown the safety bounds of such device. It required extremely proficient direction system and systematically monitoring. The militias are besides limited. In a demand of sustainability, the Gallic atomic engineering has to germinate in order to react of the hereafter challenges.
New reactor coevalss
“ a big figure of analyses of current and expected hereafter concerns about economic and environmental issues in energy supply conclude that atomic energy demands to stay a important portion of the planetary energy portfolio ” [ 10 ]
In France, the 78.5 % of electricity supply is generated by atomic energy. However, the atomic energy still has high potency for other applications such as conveyance where current conveyances have high demand on oil. Future engineering would assist atomic energy to wider utilizations.
Different atomic works coevalss
Figure 3. History of the atomic reactor coevals
The first coevals of atomic power works was chiefly experimental reactors constructed between 1950 and 1965 [ 11 ] . France has merely built one reactor of this sort in 1963. The Generation II corresponds to the first commercial reactors as the Pressurised Water Reactor. Almost all the Gallic power workss belong to this type and coevals. Generation III will be now presented.
The 3rd coevals reactors
The demand of safety betterment
After the reactor accident in the American Three Miles Island atomic power station in 1979, followed by the catastrophe in the Ukrainian town of Chernobyl in 1986, building of new atomic power station about stopped, due to a strong international societal and political resistance. In France, this political clime stopped the building of new power works during more than 20 old ages, and leaded to the closing of 2 chief experimental fast-neutron reactor: Phenix and SuperPhenix.
Figure 4. Historic of the figure of nuclearr eactors worldwide
However, the research in atomic reactor design did n’t halt. Pulling lessons from these accidents, the safety betterment was the cardinal end of the new coevals of reactor. In fact, the nucleus harm frequence of a 2nd coevals reactor was around 10-5 per works per twelvemonth. With around 400 reactors worldwide, it represents a chance of 0.4 of a serious accident every century. An betterment of the safety was accordingly necessary, particularly if the figure of power works was traveling to increase in the hereafter.
A new coevals
The coevals III reactor is a development of the coevals II atomic reactor designs integrating evolutionary betterments. Even if the procedure is the same, betterments have been developed during the life-time of the coevals II reactor designs. The greatest going from second-generation designs is that many incorporate inactive or built-in safety characteristics. With a average value of 5*10-7, the nucleus harm frequence has been drastically enhanced.
The other major ascents are:
a standardized design for each type to hasten licensing, cut down capital cost and cut down building clip,
higher handiness and longer runing life – typically 60 old ages,
opposition to serious harm as aircraft impact,
ignitable absorbers to widen fuel life.
Increasingly they involve international coaction. Reactor providers in North America, Japan, Europe, Russia and elsewhere hold a twelve new atomic reactor designs at advanced phases of planning, while others are at a research and development phase. The different designs are detailed in Appendix 1.
The first coevals III reactors were built in Japan in 1996. In 2003, both Finland and France indicated that they will be constructing an EPR reactor.
The EPR ( European Pressurised H2O Reactor ) is one of the 3rd coevals reactors. It has been designed and developed chiefly by Areva ( Gallic company specialized in atomic energy ) , Electricite de France ( EDF, national Gallic electricity company ) in France, and Siemens in Germany. [ 12 ]
After two decennaries of research, a pilot power works has been constructed in Olkiluoto ( Finland ) since 2006. In France, a jurisprudence established guidelines for energy policy and security in 2005, after a public argument of 3 old ages. The Gallic authorities, with the support of a bulk of the Gallic people, decided to construct an initial EPR unit so as to be able to make up one’s mind by 2015 on constructing a series of about 40 of them, in order to replace the installed 2nd coevals. In May 2006A the EdF board approved building of a new 1650 MWe EPR unit at Flamanville, Normandy.
Performance of the EPR
The EPR has today really high degree of fight on the atomic reactor market, achieved through:
a high power unit scope ( more than 1600MWe )
a better efficiency ( around 36 % , due to a higher operating temperature )
a design for a 60 twelvemonth life rhythm footing
longer irradiation rhythm, and hence a better handiness factor
This new progresss allows the usage of MOX ( mix of U and Pu oxide ) , a decrease of the long term waste ( around 14 % ) and nest eggs in the uranium ingestion.
However, the EPR remain a U based reactor with all its drawbacks, as the atomic waste production or the non-sustainability of the installing.
Furthermore, serious jobs with the EPR ‘s control system have been detected by the French atomic power regulative governments. Construction holds and fabricating lacks will increase the cost of the installing up to 25 % . The aim of electricity 10 % cheaper than a 2nd coevals reactor will non be reached. Furthermore, the Flamanville reactor is the mark of different ecological associations and protests.
With a really good theoretic design, the EPR demand to convert. Its existent public presentations and its operation manner still necessitate to be evaluated. France will likely replace its aging power program by this engineering, but the pick could be unsafe if the EPR does non run into the high outlooks.
The 4th coevals reactors
Generation IV reactors ( Gen IV ) are a set of theoretical atomic reactor designs presently being researched. This research was officially started by the Generation IV International Forum ( GIF ) . It is an international collective stand foring authoritiess of 13 states, where atomic is a important portion of the energy mix.
Figure 5. States of the GIF
After some deliberation, GIF announced in 2002 the choice of six reactor engineerings. These were selected on the footing of being clean, safe and cost-efficient agencies of meeting increased energy demands on a sustainable footing.
The claimed benefits for 4th coevals reactors are [ 13 ] :
Nuclear waste that lasts decennaries alternatively of millenary.
100-300 times more energy output from the same sum of atomic fuel.
The ability to devour bing atomic waste in the production of electricity.
If these ends were reached, the atomic power will be sustainable ( but non renewable ) . The militias of fuel will be multiplied by 500. However, none of these reactors is planned to be commercialized earlier at least 2025.
The six selected systems [ 11 ] :
VHTR – Very High Temperature Reactor ( 1000A°C/1200A°C ) , helium-cooled, dedicated to hydrogen production or hydrogen/electricity cogeneration ;
GFR Gas-Cooled Fast Reactor system – helium-cooled fast reactor ;
SFR Sodium-Cooled Fast Reactor system – sodium-cooled fast reactor ;
LFR Lead-Cooled Fast Reactor system – lead alloy-cooled fast reactor ;
SCWR ( Super-critical Water-Cooled Reactor system ) – super-critical water-cooled reactor ;
MSR Molten Salt Reactor system – molten salt fuel reactor.
Figure 6. Six systems of the Generation IV
France ‘s scheme for future systems
France has expressed its primary involvement to the Generation IV International Forum, in the sodium-cooled fast neutron reactors ( SFR ) and in a secondary involvement for the Very High Temperature Reactor.
France has a considerable feedback on sodium-cooled fast neutron reactors. Two experimental reactors of this sort were already constructed and operated. They are presently dismantled. The troubles and strength are hence well-known and documented. Furthermore, this system presents many advantages:
High operating temperature ( 510 A°C alternatively of 340 in a existent PWR ) which means a better efficiency
Closed fuel rhythm ( devastation of the actinoids by recycling in a new fuel )
Thorium usage as a fuel
Breeder reactor ( creative activity of new fuel by neutron soaking up )
This sort of reactor usage virtually the all of the energy content in the U fuel whereas a traditional light H2O reactor uses less than 1 % of that energy content.
Furthermore, this reactor allows France to utilize its militias of 238U, created during the uranium enrichment. This means that breeder reactors can power the energy demands for over a billion twelvemonth. France will be so wholly fuel independent.
However, the Na reacts chemically with H2O and air. This leads to outstanding technological troubles. The fuel fabrication procedures have besides to be developed, particularly in the reprocessing of the actinoids.
A batch of research still needs to be conducted, but the proficient background and the resources allocated to the undertaking are important. A demonstrator named European Fast Reactor should be provided around 2015-20. This reactor is one of the best opportunities for a sustainable atomic energy production.
New energy usage
The CEA and its industrial spouse are besides looking at other energy production by atomic power works. The 4th coevals, and specially the VHTR, presents cardinal engineerings for atomic H production or the supply of really high temperature heat for industry.
At present, atomic fission produces about entirely electricity, which, nevertheless, histories for merely a fraction of the energy consumed worldwide. The VHTR can offer a broad scope of application: electricity production industrial heat, for CO2-free H production, for chemical procedures ( refinery, aluminum production, etc. ) , and for lower temperature applications such as desalinization or territory warming.
Two undertakings of VHTR demonstrator are presently supported by the Gallic authorities. The ANTARES undertaking [ 14 ] is developed by AREVA. This VHTR will be a demonstrator for a commercial usage be aftering around 2025. This company has the experience of High Temperature Reactor operation in Germany. Parallel to this undertaking the European Union is developing RAPHAEL [ 15 ] . This experimental reactor will be a testing platform for high temperature electrolysis and new heat transportation system.
The really high temperature immune stuffs and the engineering of really high temperature He circuits and constituents ( such as money changers ) need still to be improved. Furthermore, the H storage and big graduated table usage are still at an early phase of development. However, the production of H2O at around 1000A°C, an electricity production with an efficiency about 50 % and the possibility of high temperature electrolysis during off-peak period are an extra R & A ; D country for run intoing energy demands on a planetary graduated table.
However, the usage of atomic power works for supplying hot H2O to industrial or residential country has been in France discussed since 2002. Calculation have been performed for a heat transportation from the Buget power works to the metropolis of Lyon ( 2nd biggest metropolis of France ) [ 16 ]
Figure 7. Scheme of the heat conveyance system
The survey has shown the feasibleness of that coverage in norm over the twelvemonth. The present territory warming boilers use largely fossil fuels, this installing will be salvaging 220A 000 dozenss of CO2 per twelvemonth. The value of this nest eggs in the C market will be good point for the economical sustainability of the undertaking. In add-on, the monetary value MW.h will be around AUD $ 10, which is a truly competitory monetary value. Though, the efficiency of the power works will be decrease by 1.1 % and the high demands fluctuation will be a major issue. That is why surveies are still on-going, and any paradigm is considered at the minute.
New progresss in waste direction
Since 1976, the Gallic atomic fuel reprocessing has been taking topographic point in La Hague ( Gallic Cotentin Peninsula ) . Spent fuel discharged from reactors contains appreciable measures of fissile ( 235 U and 239Pu ) , fertile ( 238U ) , and other radioactive stuffs. The end of the PUREX procedure is to divide and insulate the Uranium and the Plutonium from the remainder of the waste.
Figure 8. Chief stairss of the PUREX procedure
These oxides represent 90 % of the used fuel. They are reprocessed to organize a new fuel: the MOX. The other stuffs are glassy and shop for a thousand of old ages. This method uses many unsafe chemicals and does non work out the waste issue. Some long term radioactive merchandises have to be monitored for 1000s of old ages and the hazard of a leak in the containment is non void. On the other manus, the measure of waste is significantly reduced.
The SPIN Project
The Gallic undertaking Separation-Incineration ( SPIN ) [ 17 ] coordinated by the CEA with the support of its industrial spouses, is analyzing the feasibleness of separation and transubstantiation of minor actinoids, to cut down the long-run hazard of geological disposal.
The DIAMEX [ 18 ] is an experimental procedure similar to the PUREX. The difference is the extraction of the minor actinoids of the general waste. These minor actinoids have an intermediate degree of radiation and a large half life. They are the chief ground of long term storage. However, it is really hard to pull out them. This new procedure developed by the SPIN is able to take 99 % of these minor actinoids.
The fission merchandises have a maximal half life of 30 old ages. After 5 periods ( i.e. 150 old ages ) they have loss the major portion of their radiation.
Different methods have been proposed to acquire rid of these minor actinoids. The chief 1 is the usage of particular designed reactors, designed to utilize the minor actinoids as a fuel. In rule, it should be possible to deduce energy from the fission of any actinide karyon. With a careful reactor design, all the actinoids in the fuel can be consumed. The whole procedure is summarized in this figure:
Figure 9. Stairss of the new fuel rhythm
The high cost of the DIAMEX procedure and absence of experimental breeder reactor bounds for the minute the involvement of this procedure. However, it has to be developed in analogue of the 4th coevals of reactor. The yoke of these two methods is the best opportunity to restrict the environmental impact of the atomic energy, and to do it sustainable.
Over the past 50 old ages, huge advancement has been made in the Fieldss of plasma scientific discipline and merger engineering. However, commanding merger power and presenting it are still in research. Materials and fuels are the chief issues, and any net energy has ne’er been produced. However, this engineering is one of the best hopes in a sustainable monolithic energy production. In fact, merger is a per se safe procedure, with a high efficiency, and short term radioactive waste. Furthermore, it does non bring forth any CO2 or atmospheric pollutants
The ITER undertaking
The ITER ( International Thermonuclear Experimental Reactor ) Organization was established in 2007 [ 19 ] . China, the European Atomic Energy Community ( via EURATOM ) , the Republic of India, Japan, the Republic of Korea, the Russian Federation and the United States of America take part to the undertaking. The end is to show feasibleness of merger power, and turn out that it can work without negative impact. For this, it will necessitate to build the biggest tokomak worldwide. This device is designed to bring forth about 500 MW of merger power sustained for up to 1,000 seconds, i.e. ten times more thermic energy from merger warming than is supplied by subsidiary warming [ 20 ] .
The ITER installing is presently built at Cadarache, near Aix-en-Provence in Southern France. The plan is anticipated to last for 30 old ages – 10 for building, and 20 of operation.
Figure 10. Construction site in Cadarache
The building began in January 2007. If all goes good, ITER will get down operations in the early 2030s, and seting merger power into the grid every bit early as 2040. The Gallic authorities has a great hope in this engineering for the terminal of the century. However, many unfavorable judgments have been addressed to the undertaking, as the fact that this engineering will non be available before a long clip. Harmonizing to many ecological associations, the money should be spent in existent renewable device alternatively of these research installings.
Since the first oil daze, France has developed its ain atomic power for electricity production. With little energy resources and a high degree of technology and scientific discipline formation, the pick of the atomic seemed to be the best at this clip. Thankss to this engineering, the state has significantly decreased its CO2 emanations and increased its energy independence. Furthermore, Gallic people have entree to one of the cheapest electricity worldwide. However, atomic power workss produce atomic waste which needs to be stored 1000s of old ages, are non renewable nor sustainable. However, there is no manner renewable and energy preservation steps could replace atomic energy in the hereafter. Changes for the following decennaries have been mandatory.
A new coevals of reactor is already on its manner. Gallic scientists have developed the EPR, an improved Pressurized water reactor with impressive theoretic consequences. Though, many issues are presently detected: the public presentations have to be tested. Furthermore, this device has the same jobs as the 2nd coevals. This engineering is a good manner to better the system for the following decennaries, but it is non sustainable in a long term – chiefly for uranium militias restrictions.
The coevals IV is designed to be the first sustainable reactors. France is peculiarly interested by the Na fast reactor because of its experience of Phenix and SuperPhenix. This breeder reactor could be able to devour different type of fuel, and devour virtually all this fuel if coupled with a new waste direction, developed by the SPIN undertaking. This will leads to an energetic independency of France for 1000000s of old ages and the production of short clip atomic waste. This ideal state of affairs demands still a batch of research and paradigms.
France is besides interested in the VHTR, in order to diversify the usage of energy, as H production or high temperature H2O production. This reactor is besides still in research, but surveies have highlighted the feasibleness of utilizing heat transportation for metropolis near bing reactors.
The merger procedure is besides prospected with the Gallic engagement to the ITER experiments. This engineering cleaner and safer than the existent fission is an early phase of development and will non be commercialized before the following century.
France have diversified its possibility of usage of its atomic power during the following decennaries. Many undertakings seems economically and environementally interesting, Generation IV and the merger could even be sustainable. However these experiments need to be tested in existent conditions. Some of them will possibly be dead terminals, but others could win. The hereafter of the Gallic energy independency depends on it. Research is the lone key.
