Miniature neutron source reactor

The Chinese built Miniature Neutron Source reactor (MNSR) is a small and compact research reactor copied from a Canadian SLOWPOKE reactor design.
The MNSR is tank-in-pool type, with highly enriched fuel (~ 90% U235 ). The tank is immersed in a large pool, and the core is, in turn, immersed in the tank. The maximum nominal power is ~ 30 kW, the power being removed by natural convection. The central core is formed of about 347 fuel rods, with 4 tie rods and 3 dummy elements distributed on a total of ten circles, each consisting of a number of fuel rods ranging between 6 and 62. A thick beryllium reflector (~ 10 cm) surrounds the core radially.
China operates two MNSRs and has supplied Ghana, Iran, Pakistan, Nigeria and Syria with reactors of this type as well as the enriched uranium to fuel them. These transfers have raised serious concerns about China's commitment to nuclear nonproliferation as the Chinese Government has not committed itself to requiring full-scope safeguards in countries receiving its nuclear-related exports and thus might be contributing to nuclear proliferation.
