A roof reflector for a small, high temperature reactor with a hot gas collector space arranged above the roof reflector comprises a side reflector arranged under the roof reflector around a reactor core with a thermal side shield arranged around both the side reflector and the roof reflector. The roof reflector is composed of individual, mutually supporting, wedge-shaped graphite blocks and is supported on the thermal side shield by means of springingly elastic fastening elements in a radially expandable manner.
