Hallam Nuclear Power Facility
The Hallam Nuclear Power Facility (HNPF) in Nebraska was a 75 MWe sodium-cooled graphite-moderated nuclear power plant built by Atomics International and operated by Consumers Public Power District of Nebraska. It was built in tandem with and co-located with a conventional coal-fired power station, the Sheldon Power Station. The facility featured a shared turbo generator that could accept steam from either heat source, and a shared control room. Full power was achieved in July 1963. The facility shut down on September 27, 1964 to resolve reactor problems. In May 1966, Consumers Public Power District rejected their option to purchase the facility from the Atomic Energy Commission (AEC). In response, the AEC announced its plan to decommission the facility in June, 1966. The facility operated for 6,271 hours and generated 192,458,000 kW-hrs of electric power. It was located near Hallam, about 25 miles southwest of Lincoln. Description The sodium-cooled graphite-moderated react ...

Thermal Efficiency
In thermodynamics, the thermal efficiency (\eta_) is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, steam turbine, steam engine, boiler, furnace, refrigerator, ACs etc. For a heat engine, thermal efficiency is the ratio of the net work output to the heat input; in the case of a heat pump, thermal efficiency (known as the ''coefficient of performance'') is the ratio of net heat output (for heating), or the net heat removed (for cooling) to the energy input (external work). The efficiency of a heat engine is fractional as the output is always less than the input while the COP of a heat pump is more than 1. These values are further restricted by the Carnot theorem. Overview In general, energy conversion efficiency is the ratio between the useful output of a device and the input, in energy terms. For thermal efficiency, the input, Q_, to the device is heat, or the heat-content of a fuel that is consumed. The des ...

Chauncey Starr
Chauncey Starr (April 14, 1912 – April 17, 2007) was an American electrical engineer and an expert in nuclear energy. Born in Newark, New Jersey, Starr received an electrical engineering degree in 1932 and a Ph.D. in physics in 1935 from Rensselaer Polytechnic Institute. Starr was vice president of Rockwell International and president of its Atomics International Division. In 1967 he became the dean of the UCLA School of Engineering and Applied Science. Six years later he founded the Electric Power Research Institute (EPRI) and was its first president. He was the first president emeritus of EPRI. Starr was a member of the board of directors at the George C. Marshall Institute, a member of the board of science advisors of the Science and Environmental Policy Project (SEPP) and, like most other members of that board, he signed the Leipzig Declaration on Global Climate Change. Starr died at his home in Atherton, California, from natural causes. The day before his death he celeb ...

Sodium Reactor Experiment
The Sodium Reactor Experiment was a pioneering nuclear power plant built by Atomics International at the Santa Susana Field Laboratory near Simi Valley, California. The reactor operated from 1957 to 1964. On December 20, 1951, the first Experimental Breeder Reactor in Idaho (EBR-I) was the first reactor to produce electricity. On July 17, 1955, the BORAX-III reactor, also in Idaho, was briefly connected to the local power grid, and went on to provide all the electric power for the nearby city of Arco and several facilities of the National Reactor Testing Station (later the Idaho National Laboratory). On July 12, 1957 the Sodium Reactor Experiment became the first nuclear reactor in California to produce electrical power for a commercial power grid by powering the nearby city of Moorpark. In July 1959, the reactor experienced a partial meltdown when 13 of the reactor's 43 fuel elements partially melted, and a controlled release of radioactive gas into the atmosphere occurred. The re ...

Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's corrosion resistance, resistance to corrosion results from the chromium, which forms a Passivation (chemistry), passive film that can protect the material and self-healing material, self-heal in the presence of oxygen. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into Sheet metal, sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products. The biological cleanability of stainless steel is superior to both alumi ...
