RELAP5-3D is a simulation tool that allows users to model the coupled behavior of the reactor coolant system and the core for various operational transients and postulated accidents that might occur in a nuclear reactor.
 RELAP5-3D (Reactor Excursion and Leak Analysis Program) can be used for reactor safety analysis, reactor design, simulator training of operators, and as an educational tool by universities.
 RELAP5-3D was developed at Idaho National Laboratory to address the pressing need for reactor safety analysis and continues to be developed through the United States Department of Energy and the International RELAP5 Users Group (IRUG) with over $3 million invested annually.
 The code is distributed through INL's Technology Deployment Office and is licensed to numerous universities, governments, and corporations worldwide.
Moata was a 100 kW thermal Argonaut class reactor built at the Australian Atomic Energy Commission (later ANSTO) Research Establishment at Lucas Heights , Sydney.
 Moata went critical at 5:50am on 10 April 1961 and ended operations on 31 May 1995.
 The reactor was shut down as it was no longer possible, after 34 years, to economically justify its continued operations.
 It was one of a group of reactors that were designed in the mid-1950s, in the United States by the Argonne National Laboratory.
 The purpose of the reactor was for training scientists, however in the mid-1970s it was expanded to include activation analysis and neutron radiography.
 Moata offered training in reactor control and neutron physics.
 Experimental data on nuclear fuel and moderator systems was also accumulated during the operation of the reactor.
 The reactor has since been permanently shutdown and with dismantling of the reactor complete the site has been completely restored.
 It was the first reactor to be decommissioned in Australia.
 In 1995 the used fuel from the reactor was unloaded and in 2006 it was shipped to the United States where it remains.
 "Moata" was dismantled in 2009.
 "Moata" is an Aboriginal name meaning "gentle-fire" or "fire-stick".
The BORAX Experiments were a series of safety experiments on boiling water nuclear reactors conducted by Argonne National Laboratory in the 1950s and 1960s at the National Reactor Testing Station in eastern Idaho.
 They were performed using the five BORAX reactors that were designed and built by Argonne.
 BORAX-III was the first nuclear reactor to supply electrical power to the grid in the United States in 1955.
Idaho National Laboratory (INL) is one of the national laboratories of the United States Department of Energy and is managed by the Battelle Energy Alliance.
 While the laboratory does other research, historically it has been involved with nuclear research.
 Much of current knowledge about how nuclear reactors behave and misbehave was discovered at what is now Idaho National Laboratory.
 John Grossenbacher, former INL director, said, "The history of nuclear energy for peaceful application has principally been written in Idaho".
The FUJI molten salt reactor is a proposed molten-salt-fueled thorium fuel cycle thermal breeder reactor, using technology similar to the Oak Ridge National Laboratory's Molten Salt Reactor Experiment - liquid fluoride thorium reactor.
 It was being developed by the Japanese company International Thorium Energy & Molten-Salt Technology (IThEMS), together with partners from the Czech Republic.
 As a breeder reactor, it converts thorium into the nuclear fuel uranium-233.
 To achieve reasonable neutron economy, the chosen single-salt design results in significantly larger feasible size than a two-salt reactor (where blanket is separated from core, which involves graphite-tube manufacturing/sealing complications).
 Like all molten salt reactors, its core is chemically inert and under low pressure, helping to prevent explosions and toxic releases.
 The proposed design is rated at 200 MWe output.
 The IThEMS consortium planned to first build a much smaller MiniFUJI 10 MWe reactor of the same design once it had secured an additional $300 million in funding.
Michael Anastasio (born 1948) led two national science laboratories during a time of transition.
 He was the director of the Los Alamos National Laboratory and president of the Los Alamos National Security LLC, the company that operates the laboratory.
 He is the former director of Lawrence Livermore National Laboratory (LLNL).
 The University of California Board of Regents appointed Michael R. Anastasio the director of LLNL on June 4, 2002.
 He started on July 1, 2002.
 In 2005 he became the president of the Los Alamos National Security LLC, and became the director of the Los Alamos National Laboratory on June 1, 2006.
 During his directorship at Lawrence Livermore, the laboratory won 25 R&D 100 Awards and maintained its world-class leadership position in high-performance computing and its application to global climate modeling.
The Integral Molten Salt Reactor (IMSR) is a design for a small modular reactor (SMR) that employs molten salt reactor technology, based closely on the DMSR design (see DMSR) from Oak Ridge National Laboratory, TN, USA, and it incorporates elements found in the SmAHTR, a later design from the same laboratory.
 The IMSR is being developed by Terrestrial Energy Inc. (TEI), headquartered in Oakville, Canada.
 The IMSR belongs to the DMSR class of MSR and hence is a "burner" reactor that employs a liquid fuel rather than a conventional solid fuel; this liquid contains the nuclear fuel and also serves as primary coolant.
The boiling water reactor (BWR) is a type of light water nuclear reactor used for the generation of electrical power.
 It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), also a type of light water nuclear reactor.
 The main difference between a BWR and PWR is that in a BWR, the reactor core heats water, which turns to steam and then drives a steam turbine.
 In a PWR, the reactor core heats water, which does not boil.
 This hot water then exchanges heat with a lower pressure water system, which turns to steam and drives the turbine.
 The BWR was developed by the Idaho National Laboratory and General Electric (GE) in the mid-1950s.
 The main present manufacturer is GE Hitachi Nuclear Energy, which specializes in the design and construction of this type of reactor.
The Transient Reactor Test Facility (TREAT) is an air-cooled, graphite moderated, thermal spectrum test nuclear reactor designed to test reactor fuels and structural materials.
 Constructed in 1958, and operated from 1959 until 1994, TREAT was built to conduct transient reactor tests where the test material is subjected to neutron pulses that can simulate conditions ranging from mild transients to reactor accidents.
 TREAT was designed by Argonne National Laboratory, and is located at the Idaho National Laboratory.
 Since original construction, the facility had additions or systems upgrades in 1963, 1972, 1982, and 1988.
 The 1988 addition was extensive, and included upgrades of most of the instrumentation and control systems.
Oak Ridge School of Reactor Technology (ORSORT) was the successor of the school known locally as the Clinch College of Nuclear Knowledge, later shorten to Clinch College.
 ORSORT was authorized and financed by the U.S. government and founded in 1950 by Admiral Hyman G. Rickover and Alvin Weinberg.
 During its existence, the school was the only educational venue in the U.S. from where a comprehensive twelve month education and training in either "Reactor Hazards Analysis" or "Reactor Operations" could be obtained, with accompanying certificates.
 Funding ended and the school was closed in 1965, shortly after authorization was extended to select U.S. universities to develop their own Nuclear Engineering curricula.
 Housed at the Oak Ridge National Laboratory, this unique venue and its renowned instructors offered its students the highest level of education of practical applications of atomic energy available at the time, and first-hand exposure to a variety of nuclear reactor designs including the legendary first graphite reactor, pool reactor, high temperature gas reactor, molten salt reactor, fast reactor and high flux reactor.
