【 摘 要 】

Technical and transient protection limits are specified on the nominal burnout safety factor, BOSFN, to avoid significant release of fission products caused by local film boiling burnout. The risk of fission product release, BOR, due to film boiling burnout is statistically determined where allowances are made to account for differences between the nominal assembly and the actual assembly. This report describes the calculational model behind BOR and how the specific numerical values were estimated. The data listed in this report enable damage calculations with COBAD to be performed for the Mark 15 assembly.
