Ceramics information from nuclear

The properties and behavior at high temperature of ceramic nuclear materials, while still far from being fully known, have been the subject of much study, and the accumulation of information on this subject has reached the point where a general survey on the present status of available knowledge... 

The nuclear design calculations for this 1000-MWe fast ceramic reactor used a conservative set of nuclear data. There is experimental evidence to suggest that calculations using these data predict (1) a neutron spectrum that is too hard (quantitative information is given in the paper by Greebler et al. (8) and (2) a positive Doppler contribution from Pu which is too large.
