2011年の東日本大震災に伴う東京電力福島第一原子力発電所の事故を契機に、軽水炉の安全性を飛躍的に高めることが期待される事故耐性燃料(ATF)の早期実用化への関心が世界的に高まり、現在、世界中の多くの国々で研究開発が進められている。本稿では、2015年より、経済産業省資源エネルギー庁の支援のもとで進められてきている、国内のATF技術開発の概要を紹介する。
In the wake of the accident at the Fukushima Daiichi Nuclear Power Plant (NPP) of TEPCO due to the Great East Japan Earthquake in 2011, interest in the early implementation of accident tolerant fuel (ATF) not only for many existing NPPs but also for future NPPs, which is expected to dramatically improve the safety of light water reactors, has increased globally, and research and development is currently underway in many countries around the world. In this article, an overview of domestic ATF technology development that has been carried out with the support of the Ministry of Economy, Trade and Industry since 2015, will be introduced.
