Analyse de la fiabilité humaine (AFH) dans le cadre d’une EPS visant plusieurs tranches

1.0 IntroductionThe Canadian Nuclear Safety Commission (CNSC) has a requirement for a generic guidance document on Human Reliability Assessment (HRA) in an existing Multi-unit Probability Safety Assessment (PSA). The purpose of this advance contract award notice (ACAN) is to signal the CNSC’s intention to award a contract for these services to:Shawn St. Germain, Principal InvestigatorIdaho National Laboratory (INL)2525 Fremont AveIdaho Falls, ID 83402United StatesBefore awarding a contract, however, the CNSC would like to provide other suppliers with the opportunity to demonstrate that they are capable of satisfying the requirements set out in this ACAN, by submitting a statement of capabilities within the posting period for this ACAN, which is twenty calendar days.If, during the posting period, other potential suppliers submit a statement of capabilities that meets the requirements set out in this ACAN, the CNSC may proceed to a full tendering process via the Government Electronic Tendering Service or by inviting bids directly from suppliers.If no other supplier submits, on or before the closing date, a statement of capabilities meeting the requirements set out in the ACAN, a contract will be awarded to the above-noted supplier.2.0 BackgroundIn today’s international nuclear industry, the Probabilistic Safety Assessment (PSA) is an essential component of regulatory and utility decision-making process. Human Reliability Analysis (HRA) provides a set of inputs to PSA and produces insights useful for nuclear power plant safety. HRA is used to account for possible human errors introduced by a nuclear power plant operating crew both prior and during postulated accidents. Studies and operating experience have shown that human errors have significant impact on the likelihood of accidents occurrence and mitigation.Human error can occur at every stage of a nuclear facility life and thus a variety of methods must be used to detect and prevent it. Among the most important aspects of operator error prevention are operator training and written procedures. The lack of proper training, as well as operational procedures and lack of mature accident management procedures have been identified as some of the major causes of human error in the nuclear industry, like Three Mile Island (TMI) in the U.S. (1979) and Chernobyl in the USSR (1986). Therefore, the need to give more consideration to the form and content of the procedures provided to operators, to cope with emergency situations was recognised.The 2011 nuclear power plant event at Fukushima Daiichi Power Plant observed the most significant importance of operator actions in stopping the event progression.One of the lessons learned from the Fukushima event, is that operational events can occur at more than one unit at the same time. The operating crew of Main Control Room (MCR) was facing the challenge of stopping the progression of fuel degradation in all 6 units.Under the development of PSA studies, it is important to have good prescriptive operating procedures, targeting a specific sequence of events in order to have a realistic PSA. Also, an accurate estimation of human error probabilities, using a selected HRA method, is important for a realistic PSA of plant safety systems.While the safety analysis is developed to evaluate event progression in one unit at a time, the operating experience showed another possibility that was not considered yet, multi‑unit event. Therefore, the PSARD has defined the need for a project to re‑evaluate the human error probabilities, credited in the PSA, specific for MU events. Such a project will be beneficial for CNSC to develop guidance for MU‑HRA to provide confirmatory evaluation. This capability and expertise by the regulator is fundamental to gain public confidence as well as contributing to safety by enhancing the efficiency and effectiveness of regulatory programs.CNSC staff will publish the project general recommendations to the national and international HRA nuclear community workshops.The work will involve the following:3.0 ObjectivesThe objective of the project is to provide information on generic guidance on Human Reliability Analysis HRA evaluation in PSA for multi‑unit event. The guidance will include a minimal set of conditions needed to credit MU human actions. As far as practical, specific requirements of Level 1 and Level 2 PSA, including SAMGs operation during a multi‑unit event progression will be investigated. As a continuation of previous two HRA projects developed for current PSA practice, the SPAR-H methodology will be the basis for this project.4.0 Scope of WorkThis project addresses the following tasks: 4.1 Assessment of MU human interactions credited in Level 1 PSA The scope of the work in this phase includes the following:Identify the initiating events that affect more than one unit [shared systems/MCR/inter tie, one unit+adjacent unit, MU IE]Select dedicated HRA related to MU Initiating Events [shared systems/MCR/inter tie, one unit + adjacent unit, MU IE], including EME deploymentRe‑evaluate and examine the MU human interactions credited in Level 1 PSA to mitigate the initiating event using SPAR-H HRA quantificationProvide insights gained by using SPAR-H HRA methods for MU events.Evaluate the descriptions of PSF SPAR-H and tailor them for Level 1 MU HRAEvaluate the multipliers of PSF and tailor them for Level 1 MU HRADevelop a dedicated table in SPAR-H method with PSF and related multipliers for MU-HRA calculationProvide insights gained by using MU PSF4.2 Report – As guidance, below is a suggested table of content for Level 1 MU-HRA report.Table of Content TOC:State of Art SOAState of Practice SOPSelection of Level 1 MU-IESelection of MU-HRAEvaluation of HRA using SPAR-HTailor PFS descriptions to MU HRATailor PSF multipliers to MU HRADevelop a new MU-HRA dedicated table similar to existing SPAR-H methodReferences4.3 Tasks to be PerformedAssessment of human interactions detailed in Level 1 PSA.The first phase of the project will cover the following tasks:A plan to describe the scope, general approach, work break and schedule of the assessmentRe‑evaluate and examine the human interactions credited in Level 1 PSA to mitigate the event using alternate HRA quantification methods.Provide insights gained by using the recommended HRA method.Prepare an assessment that includes interpretation of the results and recommendations.
