31310018D0002 31310019F0045 P00001 Attachment 1 SECTION C - Descriptions/Specifications/Statement of Work C.1 PROJECT TITLE Technical Assistance in Support of the Review of the NRC Office of Nuclear Regulatory Research Technical Reports Related to the Fire Probabilistic Risk Assessment Methods C.2 BACKGROUND With the adoption of the risk-informed, performance-based fire protection rule 10CFR50.48(c),

decisions and their technical bases are relying to a much greater extent on fire Probabilistic Risk Assessments (PRAs). In particular, those plants that already have transitioned to this alternative rule developed or are maintaining fire PRAs to estimate the plants fire risk.

The NRC in collaboration with the Electric Power Research Institute (EPRI) initially published the technical guidance and framework for developing fire PRA models in NUREG/CR-6850 (EPRI 1011989), EPRI/NRC-RES Fire PRA Methodology for Nuclear Power Facilities, which was based on a limited amount of experimental data, supplemented by expert judgment. In an effort to update this guidance, the Office of Nuclear Reactor Regulation (NRR) has worked with the Office of Nuclear Regulatory Research (RES) and EPRI to perform additional research and experiments in order to produce supplemental guidance related to certain phenomenological and practical limitations of the existing guidance. Specifically, the NRC and EPRI have drafted two reports intended to advance the state of knowledge with regard to crediting personnel suppression, obstructed radiation, fire spread between adjacent electrical enclosures, motor and transformer fires, wall and corner effects, main control board fire scenarios and probability of non-suppression floor values.

The following two reports are to be reviewed and comments developed under this task order:

Report No. 1: NUREG-2230, Methodology for Modeling Fire Growth and Suppression Response for Electrical Cabinet Fires in Nuclear Power Plants Over the past decade, modern fire probabilistic risk assessments (PRAs) have been developed using NUREG/CR-6850 (also EPRI 1011989). The results show that fire can be a significant portion of the overall site risk profile, however, the methodology was never fully piloted before implementation. As a result, additional research and development in the methods and data has been performed over the past decade to refine the estimates of risk and close technical gaps in the methodology. One aspect of the fire PRA methods and data that has not been explicitly reanalyzed is the fire growth profile and plant personnel suppression response for electrical cabinets. A simplified model of the average time to peak, steady state and decay are used to model the ignition sources heat release rate profile. For manual suppression credit, a dense collection of electrical ignition sources spanning three decades is used to represent the fire brigade and plant suppression response.

Recent research efforts focused on obtaining more detailed information regarding the fire incidents at nuclear power plants. This data collection has enabled researchers to obtain more details on the fire attributes, timeline and plant impact. This project specifically reviewed the available electrical cabinet fire incident data in an effort to update the methodology to better reflect the observed operating experience. Insights from the data review served as the basis for 4

31310018D0002 31310019F0045 P00001 Attachment 1 amending portions of the fire modeling and suppression response to more accurately align with operating experience.

The outcome of this work is a revised set of parameters that address both the fire growth and the suppression response in the context of fire scenario modeling. The set of electrical cabinet fire events were classified into either a growing or interruptible fire categorization. Interruptible fires are those that have observed ignition, but no significant growth for a period of time. Growing fires, on the other hand, experience growth immediately after ignition. Furthermore, the non-suppression event tree has been updated to better allow for early plant suppression actions.

Additional manual non-suppression bins have been added to reflect the scenario characteristics.

The results of this research may be implemented in new and existing fire PRAs for a more realistic representation of the scenario progression and suppression end states.

Report No. 2: NUREG-2178 Draft, Refining and Charactering Heat Release Rate from Electrical Enclosures During Fire (RACHELLE-FIRE)- Volume 2: Fire Modeling guidance for Electrical Cabinets, Electric Motors, Indoor Dry Transformers and the Main Control Board NUREG-2178 Volume 1 refined the heat release rates (HRRs) associated with electrical cabinets and introduced an obstructed fire plume model for refining the vertical zone of influence (ZOI). As a result, Volume 1 has been implemented in a number of nuclear power plant (NPP) fire probabilistic risk assessments (PRAs) to obtain a more realistic estimate of risk associated with electrical cabinet fires. While the methodology in Volume 1 is focused on data analysis and the ZOI, it was realized that modeling refinements associated with other aspects of cabinet fires and the location of fires should be investigated. These targeted areas are further investigated in this report.

This report describes improved methods that may increase the realism in the modeling of selected ignition sources. The areas further investigated include the treatment of flame radiation and obstructed radiation, fire propagation between adjacent electrical cabinets, HRRs for electric motors and dry transformers, fire location factor, non-suppression probability floor values and the modeling of the main control board.

BACKGROUND AND NEED FOR THE MODIFICATION The report of new Task 3, Report No. 3: NUREG-2233 Draft, Methodology for Modeling Transient Fires in Nuclear Power Plant Fire Probabilistic Risk Assessments, is yet another report which falls under the effort to maintain fire PRAs to estimate a plants fire risk. This report was not available at the time the task order was developed and authorized and, at the time, there was no clear expectation as to when Report NO. 3 would be available. The scope of work for the review of this report is the same as the other two reports.

The methods and data provided in NUREG/CR-6850 Volume II and NUREG/CR-6850 Supplement 1 resulted from an extensive effort to gather together the knowledge and best practices at that time for modeling fires in FPRAs. In some cases, the level of knowledge was not as mature as needed for supporting realism in FPRAs. For example, the aggregate results of multiple FPRAs showed that transient fires were consequential and high contributors to plant risk which is a conclusion not wholly supported by operating experience. As a result, the FPRAs developed contained oversimplifications and assumptions that lean in the conservative direction.

Over the years, the industry and the NRC have worked to develop methods and data that are more realistic and representative of the operating experience with respect to fire. This report develops improved fire modeling methods that will improve the realism of modeling transient fires 5

31310018D0002 31310019F0045 P00001 Attachment 1 in FPRAs.

This report provides new probabilistic distributions and detailed fire modeling input parameters for the modeling of transient fires in FPRAs. Distributions of ZOI enable the easy screening of targets without the need to separately calculate a ZOI via fire modeling. Detailed fire model input parameters on the fuel properties and fire growth and decay profiles can be used as direct replacement for values used in existing detailed fire models in current FPRAs. This new set of model input data replaces the more limited set of data contained in NUREG/CR-6850 and NUREG/CR-6850 Supplement 1.

C.3 OBJECTIVE The objective of this task order is to obtain technical assistance from the Southwest Research Institutes (SwRIs) Center for Nuclear Waste Regulatory Analyses (CNWRA) to assist the staff in assessing the rationality, accuracy, soundness, completeness, and comprehensiveness of the results of the research which is described in the draft reports.
