A hydraulic shock absorber of the dash pot kind for use with electrically conducting liquid such as sodium, has magnet means for electro magnetically braking a stream of liquid discharged from the cylinder. The shock absorber finds use in a liquid metal cooled nuclear reactor for arresting control rods.

Hydraulic shock absorbers

A liquid metal cooled fast breeder nuclear reactor of the pool kind has an intermediate heat exchange module comprising a tube-in-shell heat exchanger and an electromagnetic flow coupler in the base region of the module. Primary coolant is flowed through the heat exchanger being driven by electromagnetic interaction with secondary liquid metal coolant flow effected by a mechanical pump.

Nuclear reactors

An electromagnetic pump wherein a core within a tubular housing defines an annular flow path for liquid metal, the core having helical windings of metal sheathed mineral insulated conductor and each winding comprising a plurality of loops arranged in series. The windings are in direct contact with the liquid metal and thereby reduce the magnetic gap normally required in such pumps.
