Japan's stockpile of plutonium kept inside and outside the country fell slightly at the end of 2016 from a year earlier with the restart of nuclear reactors using plutonium-uranium mixed oxide fuel, the Cabinet Office said Tuesday. The decrease of around 1 ton to about ...
A cargo of reprocessed nuclear fuel containing highly radioactive plutonium left the French port of Cherbourg for Japan under heavy security on Wednesday as demonstrators protested the transport. The controversial shipment from a plant of the French nuclear group Areva located about 20 km (12 ...
A small amount of plutonium and americium was found in the urine of five workers exposed to radiation in an accident earlier this month at a nuclear research facility in Ibaraki Prefecture.
Japan's push to establish a nuclear fuel recycling program and use the plutonium created in the process was the center of an intense debate in the U.S. government four decades ago, pitting those who wanted smooth relations with Tokyo against those who worried the ...
The cause of the plutonium inhalation accident in Ibaraki Prefecture might involve factors ranging from a helium buildup to procedural mistakes in checking containers.
Four workers suffered internal radiation exposure due to inhalation of a large amount of plutonium during an inspection at a nuclear research facility in Ibaraki Prefecture on Tuesday, the operator of the facility said Wednesday. In the wake of what appears to be an unprecedented ...
The collapse of a tunnel containing radioactive waste at the Hanford nuclear weapons complex in the state of Washington has underscored what critics have long been saying: that the toxic remnants of the Cold War are being stored in haphazard conditions, and time is ...
A portion of a tunnel containing buried rail cars full of radioactive waste collapsed Tuesday at a sprawling storage facility in a remote area of Washington state, forcing an evacuation of some workers at the site that made plutonium for nuclear weapons for decades ...
Before the government launches another expensive undertaking aimed at keeping its nuclear fuel cycle policy alive, it should first examine why the Monju fast-breeder project ended in failure.
With the trouble-prone Monju fast-breeder reactor set to be scrapped and nuclear materials piling up, Japan's policy on reprocessing atomic fuel is becoming increasingly uncertain. According to a U.S. government source, the administration of President Barack Obama has had discussions on the "comprehensive advance consent" ...
North Korea may be significantly expanding its nuclear weapons production and could have added six or more weapons to its stockpile in the last 18 months, a U.S. research institute said on Tuesday. The Washington-based Institute for Science and International Security (ISIS) estimated last year ...
Recent satellite images have shown "suspicious" activity at North Korea's main nuclear site at Yongbyon, which could mean reprocessing is underway to produce more plutonium for atomic bombs, a report published by a U.S. research institute said on Monday. The report on the 38 North ...
