This paper presents a design of Curie Point Electro-Magnet (CPEM) which will be installed as a passive shutdown system for a French Sodium-cooled Fast Reactor (ASTRID) development program which is conducted in collaboration between France and Japan. To confirm CPEM design validity, a qualification program for CPEM is developed on the basis of past comprehensive test series of Self-Actuated Shutdown System (SASS) in Japan. The main outcome of this paper is results of holding force tests in hot gas, which satisfy design requirements. Moreover, the result of a numerical magnetic field analysis showed the same tendency as that of the holding force test.

In the high-level radioactive waste disposal project, backfilling the disposal tunnel using soil-bentonite mixtures has been developed. Authors have developed the shotclay method and machinery through elemental test on ground test site, and conducted in-situ verification test on Horonobe URL, underground test site deeper than 300m. In this paper, authors confirmed the workability and the quality of shotclay method in the underground conditions.

Radioactive waste needs to be managed responsibly even after the waste is transported to the final disposal site. Reversibility and retrievability are also required in high level radioactive waste disposal project. From the viewpoint of the technical feasibility of the retrievability, the development of a technology for removing the bentonite backfilling material surrounding the PEM without damaging the PEM is expected. In this paper, we selected the liquid removal technology using the water jet method and verified the feasibility of selected technology in Horonobe URL, depth of 350 meters.
