Gesellschaft Für Nuklear-Service
The Gesellschaft für Nuklear-Service mbH (GNS) carries out services in the field of radioactive waste disposal and decommissioning of nuclear facilities and operates through several subsidiaries interim storage depots for spent fuel and radioactive waste as in Gorleben and Ahaus. It was created in 1977 after the Gesellschaft für Nuklear-transporte mbH (GNT) was founded in 1974. The GNS has multiple national locations and is internationally represented as well, its headquarters are at the Frohnhauser Straße in Essen. The company has approximately 700 (Stand 2014) employees and reported in 2007 a turnover of around 200 million euros. The shareholders of the Gesellschaft für Nuklear Service are PreussenElektra (48%), RWE (28%), EnBW (18.5%) and Vattenfall (5.5%). The company is for 75% owner of the Deutsche Gesellschaft zum Bau und Betrieb von Endlagern für Abfallstoffe (DBE).

High-level Radioactive Waste Management
High-level radioactive waste management concerns how radioactive materials created during production of nuclear power and nuclear weapons are dealt with. Radioactive waste contains a mixture of short-lived and long-lived nuclides, as well as non-radioactive nuclides. There was reportedly some of high-level nuclear waste stored in the United States in 2002. The most troublesome transuranic elements in spent fuel are neptunium-237 (half-life two million years) and plutonium-239 (half-life 24,000 years). Consequently, high-level radioactive waste requires sophisticated treatment and management to successfully isolate it from the biosphere. This usually necessitates treatment, followed by a long-term management strategy involving permanent storage, disposal or transformation of the waste into a non-toxic form. Radioactive decay follows the half-life rule, which means that the rate of decay is inversely proportional to the duration of decay. In other words, the radiation from a lon ...

Dry Cask Storage
Dry cask storage is a method of storing high-level radioactive waste, such as spent nuclear fuel that has already been cooled in the spent fuel pool for at least one year and often as much as ten years. Casks are typically steel cylinders that are either welded or bolted closed. The fuel rods inside are surrounded by inert gas. Ideally, the steel cylinder provides leak-tight containment of the spent fuel. Each cylinder is surrounded by additional steel, concrete, or other material to provide radiation shielding to workers and members of the public. There are various dry storage cask system designs. With some designs, the steel cylinders containing the fuel are placed vertically in a concrete vault; other designs orient the cylinders horizontally. The concrete vaults provide the radiation shielding. Other cask designs orient the steel cylinder vertically on a concrete pad at a dry cask storage site and use both metal and concrete outer cylinders for radiation shielding. As of 2021 ...

Waste Companies Established In 1977
Waste (or wastes) are unwanted or unusable materials. Waste is any substance discarded after primary use, or is worthless, defective and of no use. A by-product, by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero. Examples include municipal solid waste (household trash/refuse), hazardous waste, wastewater (such as sewage, which contains bodily wastes ( feces and urine) and surface runoff), radioactive waste, and others. Definitions What constitutes waste depends on the eye of the beholder; one person's waste can be a resource for another person. Though waste is a physical object, its generation is a physical and psychological process. The definitions used by various agencies are as below. United Nations Environment Program According to the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes a ...

Companies Based In Essen
A company, abbreviated as co., is a legal entity representing an association of people, whether natural, legal or a mixture of both, with a specific objective. Company members share a common purpose and unite to achieve specific, declared goals. Companies take various forms, such as: * voluntary associations, which may include nonprofit organizations * business entities, whose aim is generating profit * financial entities and banks * programs or educational institutions A company can be created as a legal person so that the company itself has limited liability as members perform or fail to discharge their duty according to the publicly declared incorporation, or published policy. When a company closes, it may need to be liquidated to avoid further legal obligations. Companies may associate and collectively register themselves as new companies; the resulting entities are often known as corporate groups. Meanings and definitions A company can be defined as an "artificial per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear Decommissioning
Nuclear decommissioning is the process whereby a nuclear facility is dismantled to the point that it no longer requires measures for radiation protection. The presence of radioactive material necessitates processes that are potentially occupationally hazardous, expensive, time-intensive, and present environmental risks that must be addressed to ensure radioactive materials are either transported elsewhere for storage or stored on-site in a safe manner.Benjamin K. Sovacool. "A Critical Evaluation of Nuclear Power and Renewable Electricity in Asia", ''Journal of Contemporary Asia'', Vol. 40, No. 3, August 2010, p. 373. The challenge in nuclear decommissioning is not just technical, but also economical and social. Decommissioning is an administrative and technical process. It includes clean-up of radioactive materials and progressive demolition of the facility. Once a facility is fully decommissioned, no radiological danger should persist. The costs of decommissioning are gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vattenfall
Vattenfall is a Swedish multinational power company owned by the Swedish State. Beyond Sweden, the company generates power in Denmark, Finland, Germany, the Netherlands, and the United Kingdom. The company's name is Swedish for "waterfall", and is an abbreviation of its original name, Royal Waterfall Board (''Kungliga Vattenfallstyrelsen''). History Vattenfall (then called ''Kungliga Vattenfallsstyrelsen'' or Royal Waterfall Board) was founded in 1909 as a state-owned enterprise in Sweden. From its founding until the mid-1970s, Vattenfall's business was largely restricted to Sweden, with a focus on hydroelectric power generation. Only in 1974 did the company begin to build nuclear reactors in Sweden (the Ringhals 1 and 2 reactors), eventually owning seven of Sweden's 12 reactors. In 1992, Vattenfall was reformed as the limited liability company Vattenfall AB. At the same time, the transmission grid (220 kV and 400 kV lines) was transferred to the newly formed state agency Sve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
