France's nuclear safety authority has suspended work at a nuclear fuel plant after discovering it had underestimated plutonium levels, according to AP. The ASN safety agency says the plant in Cadarache failed to notice and then waited months to report several extra kilograms of plutonium in closed spaces used to manipulate radioactive material. The ASN said in a statement Wednesday «the incident had no consequences.» But it issued a warning to plant operators and suspended work on dismantling the plant. The plant, which manufactured fuel for nuclear plants for 40 years, is being decommissioned. It was operated by French nuclear manufacturer Areva and belongs to the state Atomic Energy Commission, which reported the excess plutonium on Oct. 6.
