B103 ABWR-II(ABWR 改良発展炉)の研究開発の現状

抄録

ABWR-II has been studied as a next generation reactor with future perspectives on energy security, global environmental protection and liberalization of electricity business in Japan. In aim to commence plant operation in the late 2010s, a preliminary concept design of ABWR-II has been developed. The design developed so far are as follows : higher level of safety and reliability by adopting passive systems and design considering severe accidents, improvement in economy by up-rating the power to 1700MWe, by rationalizing components, reducing the amount of materials, and improvement in operability and maintenability by implementing on-line maintenance.
