In 2009, Esa funded a pilot project to examine the cost and practicality of establishing a European source of material for Radioactive Power Sources (RPS).
Radioactive materials used in nuclear power generation must be isolated from human or environmental contact for thousands of years.
Rokkasho has been seen as a facility that will allow Tokyo to reduce radioactive wastes from its nuclear power plants by reprocessing spent nuclear fuel.
An energy firm has begun work on a new store for radioactive waste at Sizewell B nuclear power station.
No new plants have been ordered there since the accident at Three Mile Island in Pennsylvania in 1979 (when radioactive gas escaped from a nuclear power plant), though some that were being built were completed.
Scalding hot, but non-radioactive steam explodes from the Mihama nuclear power plant.

Wednesday a fire was reported in the Fukushima Dai-Ichi power plant that was leaking radioactive material as early as Monday.
Given its inherent risks, nuclear power has always been an exercise of mind over matter, in which human intellect seeks to harness the power of nuclear fission of radioactive materials.
These materials include low-grade waste from power stations and small devices containing radioactive materials such as cesium-137, used in some cancer treatments, cobalt-60, used in food irradiation, or americum, incorporated in sensors for oil exploration.
Instead, as the long-term costs of handling radioactive waste and decommissioning reactors have become apparent, nuclear power has turned out to be no cheaper than using fossil fuels.
Two or three others were hospitalized and released after contact with radioactive water in the partially flooded basement of a Fukushima Daiichi turbine power building.
