LONG-TERM (100-300 YEARS) INTERIM DRY STORAGE FOR SPENT FUEL: PACKAGE AND FACILITIES DEVELOPMENT INCLUDING SAFETY ASPECTS AND DURABILITY ASSESSMENT PROGRAM

摘要

In the framework of the French radioactive waste management act, the Commissariat a L'energie Atomique (CEA) has carried out a major research program on long-term interim storage of intermediate-level long-lived waste, high-level waste, and spent fuel [1]. This paper describes work on the long-term interim storage of spent fuel: container development, design of surface and subsurface storage facilities, durability and functional performance demonstrations. Section 1 describes the long-term design and safety principles, section 2 covers long-term interim storage concepts, and section 3 discusses the development and demonstration program.
