In 1982, Congress established a national policy to solve the problem of nuclear waste disposal. This policy is a federal law called the Nuclear Waste Policy Act, [20] which made the U.S. Department of Energy (DOE) responsible for finding a site, building, and operating an underground disposal facility called a geologic repository.
Units 1 through 4 at the plant. At the time of the earthquake, Unit 4 had been shut down for shroud replacement and refueling since 29 November 2010. [1] [2] All 548 fuel assemblies had been transferred in December 2010 from the reactor to the spent fuel pool on an upper floor of the reactor building [3] where they were held in racks containing boron to damp down any nuclear reaction.

Disposal in deep geological formations is being studied by the French agency for radioactive waste management (Agence nationale pour la Gestion des Déchets radioactifs), in underground research labs. [57] Three sites were identified for possible deep geologic disposal in clay near the border of Meuse and Haute-Marne, near Gard, and at Vienne.
The Fukushima disaster cleanup is an ongoing attempt to limit radioactive contamination from the three nuclear reactors involved in the Fukushima Daiichi nuclear disaster that followed the earthquake and tsunami on 11 March 2011. The affected reactors were adjacent to one another and accident management was made much more difficult because of ...
Containment systems for nuclear power reactors are distinguished by size, shape, materials used, and suppression systems. The kind of containment used is determined by the type of reactor, generation of the reactor, and the specific plant needs. Suppression systems are critical to safety analysis and greatly affect the size of containment.
Decontamination is the process of removal of radioactive contaminants on the remaining surface. Washing and mechanical cleaning are processed during the decontamination process by using the chemical reactors, and the global objective is to protect public safety and the environment. [3] The coolant is also removed and stored for proper disposal.
Chernobyl Reactors 5 and 6 are unbuilt reactors, a part of Chernobyl Nuclear Power Plant's third generation phase. Intended as RBMK-1000 units capable of approximately 1,000 megawatts each, construction began on 1 July 1981 and was partially completed by the time of the Chernobyl disaster on 26 April 1986. The reactors were abandoned afterwards ...
The West Valley Demonstration Project Act (Public Law 96-368) was passed by the United States Congress in 1980, and directed the United States Department of Energy to lead the task of solidifying and removing the accumulated nuclear waste present on the site, in addition to decontaminating and decommissioning the facility and surrounding property.
