Abstract
Probabilistic fracture mechanics investigations of the contribution of pressurized thermal shock transients to reactor pressure vessel failure probability of the reference plant for the German reactor safety study phase B, BIBLIS-B, are presented. The applied methods and the calculation model are discussed. The most important result of parametric analyses is that the postulated flaw distribution in the vessel has a dominant influence on the calculated conditional failure probability. With regard to the transient behavior the results show, that the temperature drop induced by the thermal shock has great influence on the conditional failure probability, whereas the decay rate of the temperature change has minor influence.
