{"product_id":"9780791861394","title":"Risk Importance Measures in the Design and Operation of Nuclear Power Plants","description":"\u003cp\u003eThis monograph presents and discusses risk importance measures as\u003c\/p\u003e\u003cp\u003equantified by the probabilistic risk assessment (PRA) models of nuclear\u003c\/p\u003e\u003cp\u003epower plants (NPPs) developed according to the current standards\u003c\/p\u003e\u003cp\u003eand practices. Usually, PRA tools calculate risk importance measures\u003c\/p\u003e\u003cp\u003erelated to a single “basic event” representing particular failure mode.\u003c\/p\u003e\u003cp\u003eThis is, then, reflected in many current PRA applications. The monograph\u003c\/p\u003e\u003cp\u003efocuses on the concept of “component-level” importance measures\u003c\/p\u003e\u003cp\u003ethat take into account different failure modes of the component\u003c\/p\u003e\u003cp\u003eincluding common-cause failures (CCFs). In opening sections the role\u003c\/p\u003e\u003cp\u003eof risk assessment in safety analysis of an NPP is introduced and discussion\u003c\/p\u003e\u003cp\u003egiven of “traditional”, mainly deterministic, design principles\u003c\/p\u003e\u003cp\u003ewhich have been established to assign a level of importance to a particular\u003c\/p\u003e\u003cp\u003esystem, structure or component. This is followed by an overview\u003c\/p\u003e\u003cp\u003eof main risk importance measures for risk increase and risk decrease\u003c\/p\u003e\u003cp\u003efrom current PRAs. Basic relations which exist among the measures are\u003c\/p\u003e\u003cp\u003eshown. Some of the current practical applications of risk importance\u003c\/p\u003e\u003cp\u003emeasures from the field of NPP design, operation and regulation are\u003c\/p\u003e\u003cp\u003ediscussed. The core of the monograph provides a discussion on theoretical\u003c\/p\u003e\u003cp\u003ebackground and practical aspects of main risk importance measures\u003c\/p\u003e\u003cp\u003eat the level of “component” as modeled in a PRA, starting from\u003c\/p\u003e\u003cp\u003ethe simplest case, single basic event, and going toward more complex\u003c\/p\u003e\u003cp\u003ecases with multiple basic events and involvements in CCF groups. The\u003c\/p\u003e\u003cp\u003eintent is to express the component-level importance measures via the\u003c\/p\u003e\u003cp\u003eimportance measures and probabilities of the underlying single basic\u003c\/p\u003e\u003cp\u003eevents, which are the inputs readily available from a PRA model and\u003c\/p\u003e\u003cp\u003eits results. Formulas are derived and discussed for some typical cases.\u003c\/p\u003e\u003cp\u003eThe formulas and their results are demonstrated through some practical\u003c\/p\u003e\u003cp\u003eexamples, done by means of a simplified PRA model developed in\u003c\/p\u003e\u003cp\u003eand run by RiskSpectrum® tool, which are presented in the appendices.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"ASME Press","offers":[{"title":"Default Title","offer_id":49873038115056,"sku":"9780791861394","price":124.0,"currency_code":"USD","in_stock":false}],"url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780791861394","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
