Abstract

The design of modern HTRs is based on high quality fuel. In manufacturing, this fuel quality was reached in the early eighties and has since been improved further. For normal operating conditions, irradiation testing has been performed in MTRs and in operating HTRs. In the German programme, many irradiation tests were performed under realistic conditions without any single in-pile coated particle failure. Fuel testing under severe accident conditions has provided fuel performance information up to 2500 C. In small, modular HTRs, temperatures are limited to not more than 1600 C. Here, the fuel does not suffer irreversible changes and continues to retain all safety-relevant radionuclides.
