Mark II Containment Lead Plant Program Load Evaluation and Acceptance Criteria. Generic Technical Activity A-8. Supplement Number 2

摘要

A report, NUREG-0487, provided acceptance criteria for the suppression pool dynamic loads associated with safety relief valve discharges and loss of coolant accidents for the lead Mark II plants. This was followed by Supplement 1 to NUREG-0487 which contained an evaluation of alternatives to the lead plant acceptance criteria. This final supplement 2 contains an evaluation of the interim condensation and chugging load specifications. These loads were proposed by the lead Mark II plants to address observations in full scale Mark II tests conducted in 1979.
