- From _New Scientist_, 1 February 1992, article entitled:
- "Japan's Plutonium Stockpile":
-
- "...The fault [expansion of liquid Na-carrying pipes] set back
- the reactor's date of going critical from October 1992 to early next
- year. It was only the latest in a long series of frustrations for
- Monju, which has been under construction since 1983 -- after a 10-year
- battle for permission. Even if Monju performs flawlessly, it will be
- a long way from a commercial fast-breeder. The next step will be to
- build a "demonstration" reactor to bridge the gap between prototype and
- commercial plant. The government, which persuaded electrical utilities
- to cough up 20 per cent of Monju's cost of 600 billion yen, wants private
- industry to pay for the demonstrator. But, as with the ATR (adv. thermal
- reactor), utilities have shown little enthusiasm for funding future work.
- Even the demonstrator will not be commercially viable. Tetsuo Kobori,
- deputy director of Monju construction, says that at least one or two
- further demonstrators will be needed to cut costs and simplify the design
- before the first commercial fast-breeder will enter service.
- All this means that the fast-breeder will not be a significant
- contributor to the Japanese electrical grid for at least 30 years. Last
- August, Tokyo tacitly admitted that fact by announcing an important shift
- in energy policy. It would still bring its plutonium home, but for
- consumption in conventional pressurized-water and boiling-water reactors
- (known collectively as light-water reactors)."
-
- Article underscores Japanese and international concern on
- how much plutonium Japan will stockpile from the shipments.
-
- Oh yeah, numbers. From Tatsujiro Sujuki, a Japanese nuclear engineer
- at MIT: "By 2010, Japan will have accumulated between 80 and 90 tonnes
- of fissile plutonium; 30 tonnes from Europe, 6 tonnes from Tokai and
- 50 tonnes from Rokkasho." (Tokai and Rokkasho are reprocessing plants).
-
- Or, to put it another way:
-
- "...If the reprocessing policy is maintained, Japan will have an
- enormous stockpile which will surpass in the 2020s all the military
- plutonium ever produced by nuclear superpowers for weapons use."
- (Jinzaburo Takagi, Citizens Nuclear Information Centre).
