2. Radioisotope heater unit - Wikipedia

   en.wikipedia.org/wiki/Radioisotope_heater_unit

   Diagram of a radioisotope heater unit. A radioisotope heater unit (RHU) is a small device that provides heat through radioactive decay. [1] They are similar to tiny radioisotope thermoelectric generators (RTG) and normally provide about one watt of heat each, derived from the decay of a few grams of plutonium-238—although other radioactive isotopes could be used.

3. Nuclear reactor heat removal - Wikipedia

   en.wikipedia.org/wiki/Nuclear_reactor_heat_removal

   The removal of heat from nuclear reactors is an essential step in the generation of energy from nuclear reactions.In nuclear engineering there are a number of empirical or semi-empirical relations used for quantifying the process of removing heat from a nuclear reactor core so that the reactor operates in the projected temperature interval that depends on the materials used in the construction ...

4. High-temperature gas-cooled reactor - Wikipedia

   en.wikipedia.org/wiki/High-temperature_gas...

   The high operating temperatures of HTGR reactors potentially enable applications such as process heat or hydrogen production via the thermochemical sulfur–iodine cycle. A proposed development of the HGTR is the Generation IV very-high-temperature reactor (VHTR) which would initially work with temperatures of 750 to 950 °C.

5. Nuclear thermal rocket - Wikipedia

   en.wikipedia.org/wiki/Nuclear_thermal_rocket

   A nuclear thermal rocket (NTR) is a type of thermal rocket where the heat from a nuclear reaction replaces the chemical energy of the propellants in a chemical rocket. In an NTR, a working fluid , usually liquid hydrogen , is heated to a high temperature in a nuclear reactor and then expands through a rocket nozzle to create thrust .

6. Effects of nuclear explosions - Wikipedia

   en.wikipedia.org/wiki/Effects_of_nuclear_explosions

   Energy from a nuclear explosion is initially released in several forms of penetrating radiation. When there is surrounding material such as air, rock, or water, this radiation interacts with and rapidly heats the material to an equilibrium temperature (i.e. so that the matter is at the same temperature as the fuel powering the explosion).

7. Nuclear reactor coolant - Wikipedia

   en.wikipedia.org/wiki/Nuclear_reactor_coolant

   A nuclear reactor coolant is a coolant in a nuclear reactor used to remove heat from the nuclear reactor core and transfer it to electrical generators and the environment. Frequently, a chain of two coolant loops are used because the primary coolant loop takes on short-term radioactivity from the reactor.

8. Hydrogen-moderated self-regulating nuclear power module

   en.wikipedia.org/wiki/Hydrogen-moderated_self...

   Thus, in a steady state, the uranium hydride core is slaved to the temperature of the storage trays. Other heat pipes, protruding from the uranium hydride core, deliver the nuclear generated heat from the core to a heat exchanger, which in turn can be connected to a steam turbine-generator set, for the production of electricity.

9. Steam generator (nuclear power) - Wikipedia

   en.wikipedia.org/wiki/Steam_generator_(nuclear...

   These also use heat exchangers between primary metal coolant and the secondary water coolant, and thus their secondary and tertiary cooling is similar to a PWR. A steam generator's heat-exchange tubes have an important safety role, because they separate radioactive and non-radioactive fluid systems. (The primary coolant becomes briefly ...
