Volume 3 of the license amendment request (LAR) describes the process used to assign break frequencies to welds in containment and cites two documents listed as references 7 & 8:
- 7. KNF Consulting Services LLC and Scandpower Risk Management Inc. Development of LOCA Initiating Event Frequencies for South Texas Project GSI-191 Final Reportfor 2011 Work Scope.
September 2011.
- 8. University of Texas at Austin. Modeling and Sampling LOCA Frequency and Break Size for STP GSI-191 Resolution. September 2012.
The staff notes that several versions of these documents are publically available in the NRC's Agency-wide Documents Access and Management System (ADAMS). A brief comparison of the fitted Johnson parameters in the above version of Reference 8 to Table 2.2.2 revealed differences between the LAR and the referenced document. Please confirm that Volume 3 contains the correct information from these reports and cites the correct versions of the aforementioned references. Please clarify exactly which aspects of the aforementioned references (e.g., by providing specific section or equation numbers) are used in the STP pilot application.
Response
Availability of Reference 8 for Review LAR Enclosure 4-3 Reference 8 has been sent for publication in the NRC PDR with STP transmittal letter NOC-AE-13003070 (Letter, dated December 23, 2013, M.D. Meier to the NRC Document Control Desk) in order to make it publically available for review.
Confirmation of References The two referenced documents number (7), and (8) in STP's GSI-191 submittal are shown below as listed in LAR Enclosure 4-3.

(8) 5 44 32 Tables 2.2.3-2.2.10 (7) 5 5-1 to5-4 "2 Clarification Details Weld break frequencies are estimated in NUREG 1829 (Ref. 37 of LAR Encl. 4-3). The values from this elicitation are titled "NUREG-1829 Quantiles" in Table 2.2.2 of LAR Encl. 4-3, and are identical to the values given in Table 7.19 (Pg. 7-55) of NUREG-1829 for current-day break frequencies with the exception of two additional break sizes. These two additional break sizes (in LAR Encl. 4-3, Table 2.2.2) were linearly interpolated between NUREG-1829 frequencies to be consistent with the STP probabilistic risk assessment (PRA) SBLOCA and MBLOCA bounding break sizes of 2 inches (SBLOCA-MBLOCA) and 6 inches (MBLOCA-LBLOCA). Interpolation was performed for the 5 th percentile, median, mean, and 9 5 th quantiles of the NUREG-1829 distributions as described in Section 5 of Encl. 4-3 Reference 8, and the interpolated values are shown in Encl. 4-3 Reference 8, Table 31.
The quantiles of current-day break frequencies in NUREG-1829 Table 7.19 were fit to a parametric (Bounded Johnson) distribution as described in Section 2 of LAR Encl. 4-3 Reference 8. The Johnson parameters from Table 2.2.2 of LAR Encl. 4-3 are also described in LAR Encl. 4-3 Reference 8. As described, the parameters of the Johnson distributions closely fit the 5 th percentile, median, and 9 5th percentile of the NUREG-1829 distribution values (Section 2.1, Table 3 of LAR Encl. 4-3 Reference 8) with explicitly listed parameter values in LAR Encl. 4-3 Reference 8 Table 2. The parametric fit for a Johnson distribution at the two additional break sizes at the interpolated values of 2 and 6 inches (described above) are given in LAR Encl. 4-3 Reference 8 Table 32. Estimates of the mean break frequency reported in NUREG-1829 Table 7.19 were not used in this analysis.
Reference 7 Tables 5-1 through 5-4 are the source for the values in LAR Encl. 4-3 Tables 2.2.3-2.2.10. The values from tables 5-1 through 5-4 were used as weighting factors to distribute NUREG-1829 total break frequencies across weld types and to containment locations by matching weld types with containment weld data. In LAR Encl. 4-3, conservation of NUREG-1829 total break frequency is referred to as the "top-down" portion of the "hybrid" break frequency approach. Tables 5-1 through 5-4 from reference 7 represent the product of "bottom-up" aggregation of cross-industry data on observed flaws or degradation that may lead to breaks.
