After years of nuclear energy production and use, growing pressure from spent nuclear fuel accumulation is receiving serious attention in Japan in order for the nuclear power plants to keep operating without an overflow of built-in storage pools. There are other key constraints with spent nuclear fuel management, such as the schedule of Japan's first spent nuclear fuel reprocessing plant construction and operation.

This spent nuclear fuel discharge accumulates primarily in the built-in reactor pools at those power reactor units. As spent nuclear fuel accumulation approaches the capacities of those reactor pools, some nuclear power stations are forced to supplement atreactor (AR)

The Steering Committee for Nuclear Energy published another report in June 1998, which was primarily an endorsement of the working group's report, with an emphasis on legal procedure and site selection principles. One should not overlook the fact that it was emphasized in both of these reports that because spent nuclear fuel storage is a safe and static process, virtually any business venture may be able to enter into the market of storage services, as long as it meets relevant regulatory principles.

Based on the existing amount of spent nuclear fuel stocks, Nagano (2002a,c; 2003a) projected spent nuclear fuel balances in Japan up to the year 2050, using an integrated tool SFTRACE (spent fuel storage, transportation and cost evaluation system)

With the increasing pressure of spent nuclear fuel discharge from the power plants in operation and, by contrast, uncertainties in their processing and management services, spent nuclear fuel storage in the short and medium terms has been receiving the highest priority in nuclear policy formulation in Japan. Small-scale interim storage devices, as well as capacity expansion, for example, re-racking, and shared uses of existing devices, are being introduced at a number of power stations.
