GGNS Kaowool License Amendment Request Revision 0 1.0 Scenario Evaluation with Fire PRA This report describes the fire risk assessment of the five fire zones noted below in support of a Change Analysisfor Grand Gui/NuclearStation License Amendment Request for Kaouwool Resolution. Each of these zones was examined for the risk significance associated with the indeterminate status of the Kaowool wrap material. The assessment was performed using the existing Grand Gulf Fire PRA [PRA-GG-05-001, GGNS Fire PRAQuant, Rev 0 - Draft]. The fire PRA was used to begin the evaluation of transient fires found in each on the 5 fire zones of concern. The results presented here are conditional core damage probability (CCDP) and conditional large early release probability (CLERP) for those zones where a fire has the potential to damage both safe shutdown divisions. They do not represent the change in risk due to the presence of the Kaowool wrap but instead represent a bounding calculation of the entire risk. The areas evaluated are all in the Auxiliary Building and are:

FireZone Elevation IA101 93' 1A117 93' IA211 119' 1A316 139' IA417 166' 2.0 Approach and Methodology The fire PRA fails equipment, assumes a plant trip and analyzes the resultant expected core damage frequency (CDF) and large early release frequency (LERF). The original fire PRA failed equipment that is expected to be lost in a fire in the zone with the use of flag files. These files set the failed equipment to True, indicating failure. Initiating events that are not expected to occur are set to False. As a result, this analysis determines the total CDF and LERF as surrogates for the ACDF and 6LERF.

The analysis documented herein further refines the work in the fire PRA by examining specific transient combustible based fires at specific locations within each of the identified fire areas. The risk assessment was structured to integrate with proposed resolution strategies to support deterministic compliance. To support this approach, two quantifications were performed for each postulated transient fire - 1) only Division I equipment is lost or 2) only Division 11 equipment is lost. For some of the fire zones, the original work assumed that in these locations both divisions are lost due to the fire.

Two of the Auxiliary Building fire analyses zones are part of the northeast most compartment on the specified elevation: 1A21 1, and 1A316. The eastern most portion of X.ikEngineeringand Research, Inc Page 2 of 19

GGNS Kaowool License Amendment Request Revision 0 these zones are designated as the "a" scenario and can be found pictorially in Grand Gulf Fire Modeling Report [GGNS-94-0051 Documentation of Fire Modeling for Fire Probabilistic Risk Assessment] and are quantified in the Grand Gulf Fire PRA. Analysis zone 1Al01 is a northern most cross-section of the elevation, while IAl 17 meets IAl01 perpendicularly and is on the same elevation. Analysis area IA401 encompasses the entire elevation, and will be used as a surrogate for fire zone 1A417. Because the quantitative results in the Fire PRA were below the screening criterion, no refinements were made in the original analysis of fire zone IAl01 and and fire area 1A401.

New flag files were created in order to analyze the affect of only losing a single division of equipment. The end of this section contains tables showing the failed basic events for each zone and division. Table 3-1 lists all of the basic events that are failed in each analysis. This set of basic events is failed in each location because the location of their cables is unknown; most of this equipment is balance of plant components.

Tables 3-2 through 3-1 1 list the basic events failed in each zone in order to simulate the loss of only a single division. The basic events in these tables (set to True) along with 1) the list of components that are always failed (Table 3-1 basic events set to True) and 2) the list of unaffected initiators (set to False) together form the flag file used for the specific analysis.

The results in the next section are shown with and without credit for manual fire suppression. In most cases, the construction of both fault trees is such that the fire initiator is an input to an AND gate with the fire suppression HEP and CDF (or LERF) model. Hence every cutset contains the fire suppression HEP. Calculating the CCDP and CLERP without fire suppression just requires the value to be divided out of the PRAQUANT result or "trued" in the cutset file.

The following files were used in the analysis:

The current Fire PRA did not generally credit the Kaowool (although some sensitivity cases were run) and assumed that all targets exposed to fire conditions in excess of their damage threshold were disabled. Each row in Table 3-12 lists the CCDP and CLERPfor the same zone with all divisions failed followed by the results with only either the Division I or Division 11 equipment lost. This corresponds to locating a fire adjacent to the Division I cable trays and risers or the Division II cable trays and risers. Finally, the columns designated No Credit shows the impact of disallowing the possibility for manual suppression of the fire.

The results of the analysis show CCDP values, with no manual suppression credited, ranging from a low of 2.76E-05 to a high of 1.42E-03 assuming no Division I components are disabled. The results of the companion case that assumes no Division 11 components are disabled range from a low of 9.59E-05 to a high of 1.93E-03. The highest CCDP values occur in Fire Areas IA1 17 (no Division I failures) and IA21 I (no Division 11 failures) and the lowest values occur in Fire Areas 1A 101 (no Division I failures) and

]AI 17 (no Division 11 failures).

The results of the analysis show CLERP values, with no manual suppression credited, ranging from a low of 1.99E-06 to a high of 5.78E-05 assuming no Division I components are disabled. The results of the companion case that assumes no Division 11 components are disabled range from a low of 7.31 E-06 to a high of 1.67E-04. The highest CLERP values occur in Fire Areas IAl 17 (no Division I failures) and 1A21 I (no Division 11 failures) and the lowest values occur in Fire Areas IAl 01 (no Division 1 failures) and lAIOI (no Division 11 failures).
