In Indian PHWRs (Pressurized Heavy Water Reactors), one of the major functions of the end-shield cooling system is to maintain temperature across the end-shield components uniform and thereby minimizing thermal stresses. Safety analysis considers draining of water from end-shield cooling system as one of the postulated event. In the PSA (Probabilistic Safety Analysis) Level-l study, failure to manually...
Operational Event is any event which happened at a nuclear power plant leading to an unplanned transient or significantly affecting the plant response characteristics. Such events may be caused by operator errors or equipment failures. The range of events could be from an apparently insignificant event to a transient that leads to reactor trip and subsequent actuation of designed safety systems or...
This paper presents the tasks and insights of Level-1 PSA of Rajasthan Atomic Power Station, RAPS-2 viz. Initiating Events, Event Tree Analysis, Data Analysis and Quality Assurance program. This also brings out the strengths in design and operating experiences of the oldest IPHWR. The PSA has been carried out with plant specific data to gain insights to the overall safety of the plant. In the present...
Plant Specific PSA study is the most potent tool to analyze Risk due to Nuclear Power Plant, considering design aspects, operating practices and past operating experience. It requires an optimal mixture of the critical approach of an analyst and the practical approach of an operator to develop a comprehensive and realistic Plant Specific PSA. KAPS Level-I PSA was the first comprehensive PSA carried...
PSA provides an integrated model of the overall safety of the plant, which puts the safety issues in perspective, and helps in safety decisions related to both design and operations. NAPS Level-l PSA has been completed with the objective of presenting an integrated picture of safety of the NAPS which encompasses design, operational practices, component reliability, dependencies and human reliability...
Uncertainties are integral part of Probabilistic Safety Assessment (PSA) and arising from incomplete knowledge, simplified assumptions/idealization in modeling complex process/phenomena and unpredictable variation in performance of the system under study. Uncertainties influence the decision making process and help to determine whether robust decision can be made or more information is needed first...
