Abstract

Postweld heat treatment of piping and piping components can be an extremely costly part of any outage for a nuclear utility. Any reduction in the number of pipingweldments which have to undergo high temperature heat treatment can significantlyreduce both expenditures and the length of an outage. As a result, subscribers of the EPRI Repair and Replacement Applications Program asked EPRI to examine current ASME requirements to determine if relaxation of existing requirements was technically feasible. Specifically, the subscribers asked that a review of existing discrepancies in terms of thickness and diameter observed among various sections of the ASME Boiler and Pressure Vessel Code be examined. This report was assembled to document thisreview.
