ABSTRACT:
In a gas-cooled solid-moderated high-temperature reactor where fuel elements are introduced into the core through feed pipes in the ceiling reflector, the ceiling is cooled after reactor shutdown by introducing cooled gas through centrally arranged feed pipes and by removing the gas through the other feed pipes located radially outwardly of the inlet feed pipes. This arrangement effects a flow of the gas generally radially outwardly over the ceiling reflector. After the gas is removed from the core it is circulated through a closed circuit, cooled and blown back through the inlet feed pipes into the core.
