Probability distributions of peak-clad temperature and cladding oxidation thickness in loss-of-coolant accidents for a typical boiling water reactor

The probability distributions of the peak-clad temperature (PCT) and of the maximum cladding oxidation thickness supposed to occur in the hypothetical loss-of-coolant accidents (LOCAs) for a typical boiling water reactor (BWR) are studied by a computer-simulated experiment, using the computer program MOXY-EM, one of the fuel heatup analysis codes for a BWR. The PCT is found statistically to distribute normally, and the maximum cladding oxidation thickness obeys the log-normal distribution in our survey for the LOCAs at a typical BWR.
