Abstract: A nuclear power station for location in heavily populated areas has a nuclear reactor which is surrounded by a conventional containment vessel. The containment vessel is located in a rock cavern forming a secondary containment and is supported from beneath and laterally by the floor and the walls of the rock cavern. The rock cavern is reinforced and made tight by injection of grout and a third containment is formed by the surrounding ground water which may be provided artificially. A pressure transmitting, missile protecting and non-leaktight shield is provided between the reactor and the primary containment so that the reactor is indirectly supported by the rock chamber walls.
