University Of Massachusetts Lowell Radiation Laboratory
The Radiation Laboratory at the US University of Massachusetts Lowell serves the Department of Applied Physics among others. The laboratory contains a 1 MW pool-type nuclear research reactor (UMLRR) that has been operating since 1974, a 300 kCi Co-60 gamma ray source, and a 5.5 MV Van de Graaff accelerator. Reactor First startup was January 2, 1975. A budget for the reactor is not provided from the university or from the state; funding comes from customer irradiations, grants, and the United States Department of Energy. Conversion to LEU The UMass Lowell reactor has been one of the many research reactors to make the conversion from high-enriched Uranium to low-enriched Uranium as a part of anti-terrorism security measures. The used HEU fuel was reportedly shipped to the Savannah River Site The Savannah River Site (SRS) is a U.S. Department of Energy (DOE) reservation in the United States in the state of South Carolina, located on land in Aiken, Allendale, and Barnwell ...

Lowell, MA
Lowell () is a city in Massachusetts, in the United States. Alongside Cambridge, It is one of two traditional seats of Middlesex County. With an estimated population of 115,554 in 2020, it was the fifth most populous city in Massachusetts as of the last census, and the third most populous in the Boston metropolitan statistical area. The city also is part of a smaller Massachusetts statistical area, called Greater Lowell, and of New England's Merrimack Valley region. Incorporated in 1826 to serve as a mill town, Lowell was named after Francis Cabot Lowell, a local figure in the Industrial Revolution. The city became known as the cradle of the American Industrial Revolution because of its textile mills and factories. Many of Lowell's historic manufacturing sites were later preserved by the National Park Service to create Lowell National Historical Park. During the Cambodian genocide (1975–1979), the city took in an influx of refugees, leading to a Cambodia Town and America's ...

Nuclear Fuel
Nuclear fuel is material used in nuclear power stations to produce heat to power turbines. Heat is created when nuclear fuel undergoes nuclear fission. Most nuclear fuels contain heavy fissile actinide elements that are capable of undergoing and sustaining nuclear fission. The three most relevant fissile isotopes are uranium-233, uranium-235 and plutonium-239. When the unstable nuclei of these atoms are hit by a slow-moving neutron, they frequently split, creating two daughter nuclei and two or three more neutrons. In that case, the neutrons released go on to split more nuclei. This creates a self-sustaining chain reaction that is controlled in a nuclear reactor, or uncontrolled in a nuclear weapon. Alternatively, if the nucleus absorbs the neutron without splitting, it creates a heavier nucleus with one additional neutron. The processes involved in mining, refining, purifying, using, and disposing of nuclear fuel are collectively known as the nuclear fuel cycle. Not all typ ...

Light Water Reactor
The light-water reactor (LWR) is a type of thermal-neutron reactor that uses normal water, as opposed to heavy water, as both its coolant and neutron moderator; furthermore a solid form of fissile elements is used as fuel. Thermal-neutron reactors are the most common type of nuclear reactor, and light-water reactors are the most common type of thermal-neutron reactor. There are three varieties of light-water reactors: the pressurized water reactor (PWR), the boiling water reactor (BWR), and (most designs of) the supercritical water reactor (SCWR). History Early concepts and experiments After the discoveries of fission, moderation and of the theoretical possibility of a nuclear chain reaction, early experimental results rapidly showed that natural uranium could only undergo a sustained chain reaction using graphite or heavy water as a moderator. While the world's first reactors ( CP-1, X10 etc.) were successfully reaching criticality, uranium enrichment began to develop from ...

Boral
Boral Limited is Australia's largest building and construction materials supplier, with market-leading positions in quarries, cement, concrete and asphalt. Boral is actively pursuing a decarbonisation strategy through recycling of demolition materials, converting landfill and waste to energy and transitioning to 100 percent renewable electricity. With revenue for total operations of A$2.96 billion (2022), Boral has about 9,000 employees and contractors working across 356 operating and distribution sites.

Nuclear Research Reactor
Research reactors are nuclear fission-based nuclear reactors that serve primarily as a neutron source. They are also called non-power reactors, in contrast to power reactors that are used for electricity production, heat generation, or maritime propulsion. Purpose The neutrons produced by a research reactor are used for neutron scattering, non-destructive testing, analysis and testing of materials, production of radioisotopes, research and public outreach and education. Research reactors that produce radioisotopes for medical or industrial use are sometimes called isotope reactors. Reactors that are optimised for beamline experiments nowadays compete with spallation sources. Technical aspects Research reactors are simpler than power reactors and operate at lower temperatures. They need far less fuel, and far less fission products build up as the fuel is used. On the other hand, their fuel requires more highly enriched uranium, typically up to 20% U-235, although some use 93 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Department Of Energy
The United States Department of Energy (DOE) is an executive department of the U.S. federal government that oversees U.S. national energy policy and manages the research and development of nuclear power and nuclear weapons in the United States. The DOE oversees the U.S. nuclear weapons program, nuclear reactor production for the United States Navy, energy-related research, and domestic energy production and energy conservation. The DOE was created in 1977 in the aftermath of the 1973 oil crisis. It sponsors more physical science research than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories. The DOE also directs research in genomics, with the Human Genome Project originating from a DOE initiative. The department is headed by the Secretary of Energy, who reports directly to the president of the United States and is a member of the Cabinet. The current Secretary of Energy is Jennifer Granholm, who has served ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Savannah River Site (SRS) is a U.S. Department of Energy (DOE) reservation in the United States in the state of South Carolina, located on land in Aiken, Allendale, and Barnwell counties adjacent to the Savannah River, southeast of Augusta, Georgia. The site was built during the 1950s to refine nuclear materials for deployment in nuclear weapons. It covers and employs more than 10,000 people. It is owned by the U.S. Department of Energy (DOE). The management and operating contract is held by Savannah River Nuclear Solutions LLC ( SRNS), a partnership between Fluor Corporation, Newport News Nuclear, Inc. (a subsidiary of Huntington Ingalls Industries) and Honeywell International, and the Integrated Mission Completion contract (including the former scope of the Liquid Waste Operations contract) is held by Savannah River Mission Completion, which is a team of companies led by BWX Technologies, AECOM, and Fluor.
