Methodology of calculating energy deposition for LOCA analysis

Description

Under the current method to calculate Energy Redistribution Factor (ERF), the geometric model is not large enough to cover the gamma ray's mean free path, and the rod power distribution has the vagueness of selecting the representative one. The new method uses the response, that is independent of the burnup and rod power distribution, and makes the calculation of ERF easy. The new method also includes the burn-up effect of a rod to the ERF and uses the 5x5 assembly array and the real rod power distribution. The new method applied to UCN3 cycle 1, where it is found that the current ERF has the too excessive margin compared with the ERF calculated by the new method
