Stored fuel element heat recovery - by ammonia circulating through evaporator, turbine- and condenser

摘要

Surplus heat form nuclear fuel elements which are stored in an intermediate storage basin is recovered by circulating a heat carrier agent such as NH3, which boils at low temp., by a pump through an evaporator, suspended inside the basin. The vapours, produced by it, are passed to a prime mover such as a turbine for conversion into mechanical work. The agent is liquefied in a condenser and is returned by the pump to the evaporator. Such a system is independent of any extraneous energy input. It operates profitability and helps to reduce the intermediate storage costs.
