indirect implication for spent nuclear fuel reprocessing and related management of its residues. Direct impacts increase difficulties of siting new nuclear facilities, including not only power plants but even nuclear fuel cycle facilities, namely final repositories of high-level radioactive waste (HLW). Both direct and indirect impacts give clear rise to the role and importance of storage of spent nuclear fuel.

In the next section recent efforts at managing spent nuclear fuel in Japan are reviewed. The paper also discusses the implications for the temporal and geographical aspects of the process.

CURRENT STATUS OF SPENT NUCLEAR FUEL MANAGEMENT IN JAPAN

Present Status of Spent Nuclear Fuel Management
