現在開発が進められている高速増殖炉では、冷却材とし
て液体金属、通常、液体ナトリウムが用いられている。Fast breeder reactors currently under development use liquid metal, usually liquid sodium, as a coolant.

Since it is handled at temperatures as high as ℃, the circulation pump must be highly safe and reliable. Conventionally, as circulation pumps in fast breeder reactors, mechanical pumps have been used for large flow and 7-year flow, and electromagnetic pumps have been used for medium and small flow. This conventional electromagnetic pump
The inner and outer tubes of the concentric double cylindrical tube form a duct for circulating liquid sodium, and the outer tube has stator cores arranged radially, and the inner tube has stator cores arranged radially. It is an induction type annular linear type with an internal core, a frame fitted around the outer periphery of the stator core, and ring-shaped coils arranged in multiple slots on the inner periphery of the stator core. there were. and the coil and stator core.

ウム中に配置できるので、ポンプ内で発生する損失は全
て液体ナトリウムに吸収されるので、系統全体から考え
れば電磁ポンプの効率が大きく改善されることになる。However, if the entire electromagnetic pump could be immersed in circulating liquid sodium, there would be no need to install the electromagnetic pump in the middle of piping as in the past, and it would be possible to place it inside a sodium tank, etc. The circulation system becomes more compact and the degree of freedom in design increases. And conventional electromagnetic pumps have an efficiency of 20-30%.
However, since the electromagnetic pump can be placed in liquid sodium, all losses generated within the pump will be absorbed by the liquid sodium, greatly improving the efficiency of the electromagnetic pump from the perspective of the entire system. It turns out.

In a linear electromagnetic pump, the conductor of the ring-shaped coil is formed by inserting a heat-resistant conductor such as silver-filled copper, chromium-filled copper, or alumina dispersion-strengthened copper into a seamless pipe with higher heat resistance. A drawn copper wire is used. Ceramic fiber is wrapped around the copper wire, and an inorganic paint is applied and baked to provide wire insulation. The main insulation of the ring-shaped coil is mica fiber. An electromagnetic pump comprising a tape-wrapped layer and a ceramic paper layer wrapped around the outer periphery of the tape-wrapped layer, and characterized in that a frame surrounding a stator core is filled with inert gas.
