Transient behaviour of low enriched uranium silicide plate-type fuel for research reactors during reactivity initiated accident

Yanagisawa, Kazuaki

The pulse irradiation tests were conducted on silicide mini-plate fuels, prepared for a peaceful application of nuclear energy. The major findings are: (1) Neither failure nor degradation of dimensional stability of the fuel occurred in the temperature below 400 $^{circ}$ C. Beyond that level a dimensional stability was gradually degraded with an increase of temperature. (2)The fuels were intact at energy depositions 82 cal/g but were damaged at energy depositions of 94 cal/g, where the failure mode is wither through-plate cracking or fuel melt. A failure threshold must be existed between the two values.
