Plutonium isotopes 238 Pu , 239 + 240 Pu and 241 Pu in the Baltic Sea ecosystem
Wet and dry atmospheric fallout from nuclear weapon tests is one of the most important sources of plutonium in the Baltic Sea. The other sources: plutonium releases from spent fuel facilities in Sellafield (UK) and Cap de la Hague (France) are less important. Since 26 April 1986 it has been a new source of plutonium – Chernobyl plutonium, which should be taken under note in estimation of its ra...
متن کاملProduction of Pu-238 Oxide Fuel for Space Exploration
The Savannah River Site (SRS) made significant contributions to NASA space missions via the heat source programs that provide electrical power to satellites traveling outside of earth orbit. Electrical power was supplied by converting heat from the radioactive decay of plutonium-238. The Site produced the Pu-238 in its reactors, separated the plutonium in the canyon facilities, and, for the Mul...
متن کاملSelf-protection Analysis of Denatured Thorium-plutonium Fuel
With growing demands for commercial nuclear power, there is also a growing need for better energy efficiency from nuclear power reactors. In order to reach a high burnup up to 100 MWd/kg, previous research has examined the use of thorium-plutonium mixedoxide fuel as a potential candidate for this high-burnup goal. Though the neutronics studies have looked upon this fuel type favorably, the purp...
متن کاملReactor-Grade and Weapons-Grade Plutonium in Nuclear Explosives
The most common isotope, plutonium-239, is produced when the most common isotope of uranium, uranium-238, absorbs a neutron and then quickly decays to plutonium. It is this plutonium isotope that is most useful in making nuclear weapons, and it is produced in varying quantities in virtually all operating nuclear reactors. As fuel in a reactor is exposed to longer and longer periods of neutron i...
متن کاملHow Much Disruption to Activities Could Fuel Shortages Cause? - The British Fuel Crisis of September 2000
In September of 2000 the UK experienced a blockade of oil refineries in response to rising fuel prices. These protests resulted in severe fuel supply disruptions that intensified over the course of about one week. During the peak of the crisis, travel activity by car was curtailed. This paper analyzes survey data collected about two months after the crisis utilizing the recent memory of respond...
