Learn about the history, types, benefits and challenges of small modular reactors (SMRs), a class of small nuclear fission reactors designed to be factory-built and modular. Find out how SMRs can contribute to decarbonization, nuclear proliferation and safety.
A radioisotope thermoelectric generator (RTG) is a type of nuclear battery that converts the heat from radioactive decay into electricity. RTGs are used in spacecraft, satellites, remote facilities, and some medical devices.
Learn about the history, design, and challenges of nuclear microreactors, a type of small and modular nuclear power plant. Nuclear microreactors are 100 to 1,000 times smaller than conventional reactors and can be deployed to remote or isolated locations.
A comprehensive table of small modular reactors (SMR) by name, gross power, type, producer, country and status. SMR are smaller and scalable nuclear reactors that offer safety, construction and economic benefits.
The KRUSTY reactor was run at full power on March 20, 2018 during a 28-hour test using a 28 kg uranium-235 reactor core. It reached 850 °C (1,560 °F) and generated about 5.5 kW of fission power. The test evaluated failure scenarios including shutting down the Stirling engines, adjusting the control rod, thermal cycling, and disabling the heat ...
The Systems Nuclear Auxiliary POWER (SNAP) program was a program of experimental radioisotope thermoelectric generators (RTGs) and space nuclear reactors flown during the 1960s by NASA. The SNAP program developed as a result of Project Feedback, a Rand Corporation study of reconnaissance satellites completed in 1954. [ 1 ]
A nuclear reactor is a device that controls a nuclear chain reaction to produce heat, which can be used for electricity, propulsion, or other purposes. Learn how fission, neutrons, control rods, and moderators work in different types of reactors and their applications.
Learn about the history, benefits and challenges of thorium-based nuclear power generation, which uses uranium-233 produced from thorium as fuel. Find out how thorium reactors can offer advantages over uranium reactors, such as lower weaponization potential, reduced waste production and higher efficiency.
