The completion date of the Rokkasho Reprocessing Plant has been postponed 27 times. During the 31 years construction period, the construction cost has ballooned to 3.4 trillion yen, 4.5 times the initial estimate, and the total project cost including other nuclear fuel cycle facilities has reached 17.5 trillion yen. Reprocessing is advertised as if nuclear fuel can be reused repeatedly, but without a fast breeder reactor, it can be used only once at best in plutonium thermal power generation. Because of degrading of the fissile contents in plutonium, re-reprocessing has no merits. MOX fuel is 5 to 13 times more expensive than uranium fuel, even when imported, and 20 to 50 times more expensive when produced domestically so that MOX fuel only increases costs. In February, the United Kingdom announced a policy to dispose of over 100 tons of civilian plutonium. Plutonium, which has become a bad debt, no longer has any meaning to be extracted from spent nuclear fuel, and the process scatters enormous radioactivity into the environment, which causes health damage to surrounding residents. Environmental pollution was observed in Rokkasho Village at the test stage. Reprocessing should not be promoted.
