摘要：
A method of calculating the probability of a leak occurring in the main joint of the reactor and the probability of the head detaching from the vessel body of VVER-TOI as a result of stud-bolt failure and the computational results are presented. The stresses in the stud bolts are calculated taking account of their redistribution in intact stud bolts for different numbers of failed stud bolts. In the calculations of the stud bolt failure probability, the statistical characteristics of the mechanical and strength properties of the material, the characteristics of the means of nondestructive flaw detection in the material, and the probability that defects are missed during checks are taken into account.
