Abstract

The subject of the paper is the accident analysis and accident control of the thorium high temperature reactor, the THTR, which has been under construction in Hamm/Uentrop since 1972. At present all buildings, the concrete pressure vessel and the cooling tower are erected and all major components of the primary circuit and the turbo machinery are installed. In the paper following subjects are discussed: the reactor scram system, the decay heat removal system, the activity enclosure or penetration closure system and also the problem of interaction of the safety systems
