Operational Guidance to Improve Industry Benefit of Alternate Equipment and Strategies
The PWROG has recently championed several efforts to increase collaboration between Probabilistic Risk Assessment (PRA) experts and nuclear power plant operators and procedure writers. The result of these efforts has allowed for nuclear power plants to risk inform plant procedures to reduce risk and promote the health and safety of the public. A key insight from this collaboration was the need for, and development of, an industry framework for generating written guidance to increase the benefit of alternate strategies. As the industry expands the use of alternate equipment (installed or portable), standardization of terminology, application, and PRA modeling of flexible equipment operation is desired. To that end, a new category of industry Guidelines has been defined: “Flex Support Guidelines Additional Defense in Depth” (FSG+DD). The new Guideline categorization maximizes the use of defense in depth and minimizes the need for flexible equipment to fall into regulatory required maintenance (Maintenance Rule Scope). FSG+DD strategies may be utilized to supplement current guidance used to maintain or restore a function when the plant is outside a Design Basis credited mitigating strategy. Additionally, these strategies may be utilized within a plant’s Design Basis to compensate for equipment that is inoperable and unavailable, or to maintain a function. This paper will discuss the Risk Informed Procedure Writers Guide developed by the PWROG to form the framework for the industry’s expanded use of flexible equipment.
