Inherent Safe Design of Advanced High Temperature Reactors - Concepts for Future Nuclear Power Plants

摘要

This paper discusses the applicable solutions for a commercial size High Temperature Reactor (HTR) with inherent safety features. It describes the possible realization using an advanced concept which combines newly proposed design characteristics with some well known and proven HTR inherent safety features. The use of the HTR technology offers the conceivably best solution to meet the legal criteria, recently stated in Germany, for the future reactor generation. Both systems, block and pebble bed reactor, could be under certain design conditions self regulating in terms of core nuclear heat, mechanical stability and the environmental transfer.
