The quantitative failure mechanism of the silicide and aluminide fuels (the test specimens) was studied using the 4.8 g/cc silicide fuels as the references. (1) The onset of the departure from the nucleate boiling (DNB) was determined to be 188±27°C for the test specimens and 182±15°C for the references. The difference was insignificant. (2) The failure mechanism of both fuels was attributed to the quench stress that occurred owing to the uneven temperature profile across the fuel plate. In-core quantitative data indicated that when the temperature drop ΔT was greater than 94°C and the time to quench tq was shorter than 0.13 s, through-plate cracking could occur. (3) Irrespective of the fuel initial density, the plate bow increased with an increase in the PCST. The worst bow up to 228°C (JRR-3 operational limit) was 15%.
