In the meantime, annual maintenance outlays of an estimated 50 million yen are going to be required for the RETF, which will likely give rise to public controversy about the cost effectiveness of completing the RETF.
The total cost of building the RETF was originally budgeted at 120 billion yen.
The RETF constitutes part of the project, in which the Monju fast-breeder reactor is supposed to produce more plutonium than it consumes through use of plutonium-uranium mixed oxide fuel.
The Ministry of Education, Culture, Sports, Science and Technology argues that the RETF cannot be scrapped and that a minimum amount in maintenance costs should continue to be disbursed.
On the other hand, a source close to the issue points out that the work on the EETF went ahead faster than the work on the Monju so the agency halted the construction of the RETF abruptly in 2000.
RETF would be the leading-edge facility for such work.
RETF was interested in liquid hydrogen as a rocket fuel.
For example, the decision to use hydrogen to power the upper stage in the Saturn rockets was primarily due to missionary work by RETF personnel.
In Spring of 1993, the government started to construct the RETF using a total budget of twelve billion Yen.
Japanese mass media have been very silent about the RETF plan.
Tsuchida warns that the forty kg of plutonium that existed at Joyo in 1993 could produce twenty tactical nuclear weapons by the RETF.
The United States transferred these technological advances to the RETF in Japan.
