Japan Nuclear Fuel skipped safety checks at Rokkasho plant for 14 years

Nuclear regulators concluded Wednesday that Japan Nuclear Fuel Ltd. violated legally binding safety rules by failing to conduct necessary checks for over a decade at its uncompleted spent nuclear fuel reprocessing plant in the countrys northeast.
The failure of checks at an underground portion of the plant in the village of Rokkasho in Aomori Prefecture for about 14 years eventually resulted in about 800 liters of rainwater flowing into a building housing an emergency diesel generator in August this year. The generator is a crucial device in times of crisis such as the loss of external power.

But the Rokkasho plant has been inundated with problems, with its completion date postponed 23 times since 1997, its initial target. It also had to meet new, tougher safety standards made in the wake of the crisis at the Fukushima No. 1 nuclear power complex, triggered by the powerful March 2011 earthquake and tsunami that devastated parts of the Tohoku region.
The authority also said holes and cracks at exhaust pipes found at Japan Nuclear Fuels uranium enrichment plant in September also violated safety rules. The defects had been undetected due to a lack of inspections.
