Probabilities of Failure and Uncertainty Estimate Information for Passive Components - A Literature Review

NUREG/CR-6936 PNNL-16186 Pacific Northwest National Laboratory U.S. Nuclear Regulatory Commission Office of Nuclear Regulatory Research Washington, DC 20555-0001 2007 Date Published: May 2007 Prepared by: S.R. Gosselin, F.A. Simonen, S.P. Pilli, B.O.Y. Lydell NRC Job Code N6019 This report describes a study performed for the U.S. Nuclear Regulatory Commission by Pacific Northwest National Laboratory with subcontractor support from Sigma-Phase, Inc. The effort involved reviewing the open literature to collect estimates of failure probability and their associated uncertainties for passive reactor components. The review focused primarily on probabilistic structural mechanics evaluations of plant-specific components for domestic nuclear power plants with pressurized water reactors or boiling water reactors as well as for international plants of similar design. A computerized search of several databases identified more than 7500 documents, of which only a small fraction were related to probabilistic structural mechanics calculations. Probabilistic treatments and characterizations of fatigue and stress corrosion cracking were found to be well represented in the literature, but only a limited number of the publications described plant-specific and component-specific probabilistic evaluations based on actual design or operating stresses. The NRC will apply these results during the development of probabilistic fracture mechanics tools to generate failure probabilities for passive reactor components for use in regulatory decision making. A Special Forces squad are betrayed! Perfect for fans of Andrew Watts, L. T. Ryan, Don Keith and George Wallace. Captain Gerber and his men are about to become sitting ducks Vietnam, 1968 The CIA know that the enemy has been secretly operating in neutral Cambodia since the beginning of the Vietnam War. But now the NVA are elevating Cambodian officers into positions of power as a reward for their cooperation. Their to shift Cambodia from being neutral to openly helping the Communists.American intelligence and military officials plan to thwart the enemys objective by eliminating any Cambodian military officer assisting the North Vietnamese.U.S. Army Special Forces Captain Mack Gerber and Master Sergeant Anthony Fetterman are called on to lead a sniper squad across the border to assassinate a key Cambodian General.Its a covert in-and-out mission. But the mission has been compromised.Now Gerber and his men will have to fight their way out of the jungle if they are to survive.
