IAEA-TECDOC--1366: Considerations in the development of safety requirements for innovative reactors: Application to modular high temperature gas cooled reactors

International Atomic Energy Agency, Vienna (Austria)

Abstract

In this TECDOC, the MHTGR has been selected as a case study to demonstrate the viability of the method proposed. The approach presented is based on an extended interpretation of the concept of defence in depth and its link with the general safety objectives and fundamental safety functions as set out in “Safety of Nuclear Power Plants: Design”, IAEA Safety Standards No. NS-R.1, issued by the IAEA in 2000. The present TECDOC is not intended to be exhaustive, but rather suggests a systematic approach to be used in the development of detailed safety requirements.
