Romashka reactor
Template:Infobox nuclear reactor
The Romashka reactor (Template:Langx) was a Soviet experimental nuclear reactor. It began operation in 1964, and was developed by the Kurchatov Institute of Atomic Energy. The reactor used direct thermoelectric conversion to create electricity, rather than heating water to drive a turbine.[1] It is thus similar to a radioisotope thermoelectric generator, but higher power.
The Romashka reactor was developed with the intention of using nuclear power in space satellites, but was superseded by the more powerful BES-5 reactor. The project was canceled after the death of Sergei Korolev, who was heavily involved in the project.Script error: No such module "Unsubst".
Reactor design
The fuel was Script error: No such module "val". of highly enriched uranium (90% Script error: No such module "Su".U) in the form of UC2 (uranium carbide).[2][3][4] A beryllium reflector was used on the ends of the reactor, and electricity was generated using silicon-germanium semiconductors.
The Romashka reactor didn't use liquid coolant; it was designed to be simple, compact, and light. Temperature was self-regulated through the use of a negative temperature reactivity coefficient. The successful demonstration of the Romashka reactor provided a baseline for further developments in Soviet nuclear power for space satellites.Script error: No such module "Unsubst".
The experimental reactor was started (reached criticality) in 1964 and decommissioned in 1966, and was used to research the concept of direct energy conversion.[4] It produced Script error: No such module "val". of heat,[2][4] and reached temperatures of Script error: No such module "convert"..The reactor operated for Script error: No such module "val"..[5]
