James, L. A.

The techniques of linear-elastic fracture mechanics were employed to estimate the in-service extension of hypothetical flaws in two LMFBR primary piping elbows. The paper describes the technical basis for the conclusion that very little crack growth will occur in these components due to either the anticipated normal, upset, and emergency events, as well as some unlikely ''abnormal'' events. The two examples treated include a hot leg elbow and a cold leg elbow. The assumptions and approximations concerning stress and loading conditions, the expected in-service operational environment, and material property behavior are discussed in detail. Based upon the analyses, it is concluded that significant crack extension is very unlikely under these LMFBR primary piping conditions.
