It was powered down in 1996 for maintenance, and while closed faced court challenges that prevented its restart and it was closed permanently.Currently only two industrial-grade fast reactors are in operation – the BN-600 and BN-800 at Russia’s Beloyarsk NPP. Japan cancelled its own €7.8 billion Monju prototype fast-breeder project in 2016 due to heavy costs and had viewed ASTRID as central to its plans to recycle used fuel.ASTRID, a sodium-cooled fast reactor prototype was to be built at the Marcoule nuclear site in the Gard to make possible the use depleted uranium and plutonium as fuel in order to reuse used fuel mostly stored at the La Hague site, operated by Orano (formerly Areva). The sodium-cooled fast reactor (SFR) is the reference technology for those countries having embarked on the development of Generation IV fast reactors. 2667 0 obj

In France, studies are being led by the CEA via the ASTRID project, which will benefit from the oper… France has a history of failed fast reactor projects. ASTRIDの研究開発と検討への参加 建設における包括的協力プログラム ナトリウム高速炉に関する日本 ASTRID was to be the successor to France’s three experimental fast reactors – Rapsodie, Phenix, and Superphenix – all of which have been decommissioned.
This technology has been the subject of numerous projects throughout the world, which has led to more than 400 reactor years of operation, including 100 years of industrial operation. After 2004, it was used to investigate transmutation of nuclear waste and also generated some electricity. It operated until 1983, when it was shut down permanently. �a���s"x�K:��@����8no��{-���j�JLT��� �cj����1(��ƃ��� 2639 0 obj

Japan viewed Astrid as central to its plans to recycle spent nuclear fuel and was expecting to cooperate with France on the project in order to continue its own research into fast breeder reactors. A few other countries, including China and India, have operational experimental installations with fast-breeder reactors. Le projet est « doté des meilleurs standards de sûret… It was a pool-type liquid-metal fast breeder reactor cooled with liquid sodium. �����d'$���Ӫ-5(��oв�G&���|�(��

According to the Court of Auditors, nearly €738 million ($811m) had been invested in this plan by the end of 2017, including nearly €500 million as a large loan from the Investments for the Future programme. In 2010, Astrid was granted a €652 million ($742 million) budget.
CEA told Reuters it would propose a new programme for ASTRID’s development later this year.France has a history of failed fast reactor projects. ASTRID was to be the successor to France’s three experimental fast reactors – Rapsodie, Phenix, and Superphenix – all of which have been decommissioned. Phénix closed in 2009.The 1,242 MWe Superphénix was intended to reprocess nuclear fuel from conventional nuclear reactors, while also generating its own power. Phénix ran without problems through the 1970s and 1980s, but in the early 1990s experiencedunexplained behaviours, including large power transients. 計画とインフラに関する協力 3. CEA told Le Monde that "the project to build a prototype reactor is not planned in the short or medium term" but will be deferred until " the second half of the century”. CEA’s recent decision confirms reports in the Japanese press last November that the French government had informed Japan it would halt their joint development of ASTRID. Construction of the 22 MWt Rapsodie started in 1962 and it went critical in 1967. endstream

< ASTRID の燃料 2. In November 2018, CEA had already said it was considering reducing Astrid’s capacity from the originally planned 600MW commercial size to a 100-200MW research model. Some design studies still in progress will continue this year but will be shelved after the 25-person unit coordinating the programme was closed in the spring. フランスにおける 高速炉（ASTRID）について 日本原子力研究開発機構 佐賀山 豊 平成26年3月12日 自由民主党 資源・エネルギー戦略調査会 放射性廃棄物処分に関する小委員会 It …
Construction began in 1974 but cost overruns, delays and public protests delayed grid connection until 1986. ASTRID (Advanced Sodium Technological Reactor for Industrial Demonstration) was a proposal for a 600 MW sodium-cooled fast breeder reactor (Generation IV), proposed by the Commissariat à l'énergie atomique (CEA).
