Safety Analysis of Kuosheng Mark III SRV Piping Response to Discharge Loading

摘要

The Taipower Company of Taiwan performed several safety relief valve (SRV) discharge tests at the Kuosheng Nuclear Power Station in August 1981. The tests included single, consecutive, and multiple valve actuations performed to verify design adequacy of plant piping, structures, and equipment by measuring accelerations and strains throughout the containment facility. The test instrumentation was provided by Nutech International and Bechtel Power Corporation. This paper describes a safety analysis of the Kuosheng Mark III SRV piping performed to predict its response to discharge loading. Results of the dynamic analysis were used to show that stresses in the SRV piping and its supports due to discharge loading fall within safe limits prescribed by the ASME Boiler and Pressure Vessel Code. The experimental results were used to support this position. This evaluation did not include stresses resulting from thermal expansion of the pipe nor fatigue effects from numerous valve actuations.
