PROTECTION SYSTEM FOR THE REACTOR PROTECTION BUILDING IN A NUCLEAR POWER PLANT.

摘要

A protection system for the reactor-containing building in nuclear power stations comprises a structure disposed below the reactor and submerged in a cooling fluid, the structure intercepting the molten material escaping from the reactor on melt-down of the reactor core, such that the molten material is distributed over a large heat transfer area and transfers its heat to the cooling fluid.
