Estimation of Failure Frequency for Type I and II High Level Waste Tanks

摘要

The failure frequency of Type I and Type II High Level Waste tanks wascalculated. The degradation mechanism that could lead to large break failure and the credits taken for steps taken to prevent large break failure were considered. The annual probability of failure or failure frequency of the the Type I and Type II High Level Waste Tanks was estimated to be 1 x 10(sup-8) large breaks/year (per tank).
