The present work of T.T. and T.M. is partially supported by the Japanese Grant-in-Aid for Scienhhc Research Fund of the Ministry of Education, Culture, Sports, Science and Technology (11640272, 13640282), and by the REIMEI Research Resources of Japan Atomic Energy Research Institute (JAERI). 

The sample used for the experiments is Aciplex-SF-1004 (10x10x0.117 mm3). The sample was irradiated at room temperature and atmospheric pressure with 1.17 and 1.33 MeV gamma-ray from a cobalt-60 source in the Takasaki Research Establishment of Japan Atomic Energy Research Institute (JAERI). The absorption doses of the sample by gamma-ray were from 1 to 173 kGy. 

The neutron-diffraction experiments were carried out at the JRR-3M Research Reactor, Japan Atomic Energy Research Institute (JAERI), Tokai-mura, using the... 

Electrodialysis has been examined [26] at the Japan Atomic Energy Research Institute (JAERI) for the removal of radioactive ions from low- and intermediate-level radioactive liquid waste using inactive coexisting salts as ionic carriers of very small amounts of radioactive ions. It has been found that the nature and the concentration of the existing salt species generally do not influence the decontamination factor obtained for radioactive ions. The efficiency for the decontamination of radioactive ions has been found to be higher for lower valence cations. It has also been observed that addition of inactive coexisting salt ions improves the decontamination factor but lowers the extent of volume reduction achievable. 

The separation of actinides has been studied for various purposes in Japan Atomic Energy Research Institute (JAERI). The works which have been carried out so far, are classified into four categories preparation studies of actinides nuclides, separation chemistry for chemical analysis, separation of actinides from radioactive waste, and studies on reprocessing of spent nuclear fuels. The present work is to review studies of actinide separation performed in JAERI, emphasizing the need of the separation for the main purpose of individual. Concern is focussed on the separation of transuranium elements and studies on thorium and uranium are put aside.

Related research and development works are underway at several organizations under the discussion and coordination of the Japanese FBR R D Steering Committee, which is composed of Power Reactor and Nuclear Fuel Development Corporation(PNC), JAPC, Japan Atomic Energy Research Institute(JAERI) and Central Research Institute of Electric Power Industry(CRIEPI). 

A brief description of the development of forging components in the Japan Steel Works (JSW) is as follows. JSW supplied the plates for the RPVs in the Japan Power Demonstration Reactor (JPDR) of the Japan Atomic Energy Research Institute (JAERI) in 1961 and the Japan Atomic... 

The design study has been performed by the Japan Atomic Energy Research Institute (JAERI) continuously since 1983 co-operating with Ishikawajima-Harima Heavy Industries, Co. Ltd. and Mitsubishi Heavy Industries, Ltd. 

To accomplish this plan, the sodium cooled experimental reactor JOYO is now under operation in the Japan Atomic Energy Agency (JAEA), a new organization combining the former Japan Nuclear Cycle Development Institute (JNC) and Japan Atomic Energy Research Institute (JAERI). The JOYO reactor is being operated to develop and validate sodium, fuel, and material technologies, etc. 

LEM, LIM and LRM are the essential technologies to realize the RAPID they have been acquired through the following R D conducted in 1999-2001 with the support of Japan Atomic Energy Research Institute (JAERI, currently IAEA — the Japan Atomic Energy...
