Electronic Archival of the Results of Pressurized Thermal Shock Analyses for Beaver Valley, Oconee, and Palisades Reactor Pressure Vessels Generated with the 04.1 version of FAVOR T. L. Dickson S. Yin Oak Ridge National Laboratory P. O. Box 2009 Oak Ridge, TN, 37831-8056 Abstract The current federal regulations to insure that nuclear reactor pressure vessels (RPVs) maintain their structural integrity when subjected to transient loading conditions such as pressurized thermal shock (PTS) events were derived from computational models developed in the early-mid 1980s. Since that time, there have been advancements in relevant technologies associated with the modeling of PTS events that impact RPV integrity assessment. These updated computational models have been implemented into the FAVOR (Fracture Analysis of Vessels: Oak Ridge) computer code.

An objective of the United States Nuclear Regulatory Commission (USNRC) PTS rule re-evaluation project is to determine if the application of improved technology can provide a technical basis to reduce the conservatism in the current regulations while continuing to provide reasonable assurance of adequate protection to public health and safety. A relaxation of PTS regulations could have profound implications for plant license renewal considerations. As part of the PTS re-evaluation project, to date, the 04.1 version of the FAVOR [1-2] code has been applied to three domestic commercial pressurized water reactors (PWRs): Beaver Valley Unit 1, Oconee Unit 1, and Palisades Unit 1.

The objective of this report is to document the electronic archival of the PTS analysis results, including the input data files and the output data files generated by the 04.1 version of FAVOR, for these three PWRs. This archival should provide sufficient detail such that the analysis results, and subsequent conclusions, can be reproduced. This report also contains summary reports of the analysis results. The results reported herein have been incorporated into an integrated document that proposes a technical basis for a revision of the PTS screening criteria [3]

1. Introduction Table 1 is a summary of the integrated risk-informed PTS analysis results of Beaver Valley, Oconee, and Palisades which were generated with the 04.1 version of FAVOR [1-2] as part of the NRC-sponsored PTS Re-evaluation Program. Table 1 contains the mean values of the probability distributions for the frequency of crack initiation (FCI) and the through-wall cracking frequency (TWCF). For each of the three PWRs, analyses were performed at four levels of embrittlement, each one in principal, corresponding to a particular point in the operating life of the RPV.

For Oconee and Palisades, detailed neutron fluence maps were provided by Brookhaven National Laboratory (BNL) corresponding to 32 and 40 effective-full-power years (EFPY). For Beaver Valley, the same maps were provided by Westinghouse. The modeling and procedures used in generating these neutron flunece maps were based on the guidance provided in the NRC Draft Regulatory Guide DG-1053

[4]. The calculations were performed using the DORT discrete ordin ates transport code [5] and the BUGLE-93 [6] forty-seven neutron group ENDF/B-VI nuclear cross sections and fission spectra. The Eason and Wright irradiation shift model, as specified in Equation 84 of reference 1, was used to calculate the irradiation-induced Charpy-transition-temperature shift RTNDT .

Neutron fluence maps for times in the operating life of the RPV later than 40 EFPY were obtained by linear extrapolation from the maps for 32 and 40 EFPY. The assumption associated with this extrapolation is that the current core refueling scheme is maintained. This assumption is also implicit in the fluence maps for 32 and 40 EFPY. The first two analysis results were performed with neutron fluence maps that correspond to 32 and 60 EFPY. Clearly, some of the extrapolations used in these analyses are far beyond the range of EFPY for which plants would ever actually operate. They were performed since an objective of the analyses was to determine the level of embrittlement that corresponds to a frequency of RPV failure in the 10-6 to 10-7 range.

The objective of this report is to document the electronic archival of the PTS analysis results, including the input data files and the output data files generated by the 04.1 version of FAVOR, for these three PWRs. This archival should provide sufficient detail such that the analysis results, and subsequent conclusions, can be reproduced. This report also contains summary reports of the analysis results.

2. FAVOR Data Streams Figure 1 illustrates the nature of the data streams that flow through the three computational modules of the FAVOR code. The three modules of FAVOR are: (1) a deterministic load generator (FAVLoad), (2) a Monte Carlo PFM module (FAVPFM), and (3) a post-processor (FAVPost). Figure 1 indicates the nature of the data streams that flow through these modules.

10

Figure 1 Data streams flow through three FAVOR modules: (1) FAVLoad, (2) FAVPFM, and (3)

FAVPost.

The input data requirements and resulting output data of the FAVLoad module are as follows:

FAVLOAD input dataset - contains vessel geometry, thermal-elastic material properties, stress free temperature, and transient definitions, i.e., thermal hydraulic boundary conditions applied to the RPV inner surface for each transient in the form of time histories for convective heat transfer, coolant temperature time history, and pressure. The electronic archive, which this report documents, contains all of the FAVLoad input datasets used in the PTS analyses for the three PWRs. The thermal-hydraulic analyses were performed by Information Systems Laboratories (ISL) using the RELAP 5/MOD3 computer code [7].

11

FAVLOAD output dataset - contains circumferential and axial stress time histories for various through-wall locations in the RPV wall and applied KI time histories for various inner-surface breaking flaw geometries for each of the transients. The FAVLoad output dataset becomes one of the input datasets to the FAVPFM module. The FAVLoad output files are not included as part of this archive because (1) the size of the output files are quite large, and (2) they can easily be generated in a minimum amount of computational time by applying the FAVLoad (v04.1) module.

The input data requirements of the FAVPFM module are five input dataset as follows:

(1) FAVLoad output dataset (discussed above)

(2) embrittlement-related (chemistry and neutron fleunce) data of the RPV beltline Three flaw characterization files as follows:

(3) inner-surface breaking flaws (applicable to weld and plate material)

(4) embedded flaws for weld material (5) embedded flaws for plate material The chemistry data was taken from the RVID database [8]. The flaw-characterization data was provided by Pacific Northwest National Laboratory (PNNL). The USNRC has supported research at PNNL that has resulted in the postulation of fabrication flaws based on the non-destructive and destructive examination of actual RPV material. Such measurements have been used to characterize the number, size, and location of flaws in various types of weld and base metal used to fabricate vessels, thus providing a technical basis for the flaw data which is critical input data into FAVOR analyses [9-11]. These measurements have been supplemented by expert elicitation [12].

The electronic archive, which this report documents, provides all of the FAVPFM input datasets used in the PTS analyses for the three PWRs except the FAVLoad output files.

The resulting output data of the FAVPFM module consists of three* output datasets as follows:

12

(1) initiate.dat - contains the conditional probability of crack initiation (CPI) for each RPV simulated in the PFM Monte Carlo analysis subjected to each transient, i.e., the (i,j) entry in initiate.dat is the CPI of the ith RPV subjected to the jth transient. This file will become an input file to the FAVPost module.

(2) failure.dat - contains the conditional probability of through wall cracking (CPTWC) for each RPV simulated in the PFM Monte Carlo analysis subjected to each transient, i.e., the (i,j) entry in failure.dat is the CPTWC of the ith RPV subjected to the jth transient. This file will become an input file to the FAVPost module.

(3) user-named PFM output file - contains informative reports that have the objective of providing useful information and insights into the fracture analysis.

The electronic archive, which this report documents, provides these three FAVPFM ouput datasets generated for each PTS analysis for the three PWRs.

  • The FAVPFM module generates additional output reports primarily used by developers for verification and validation purposes. These additional output datasets are not part of the data streams illustrated in Figure 1 and therefore will not be included in this archival.

The input data requirements of the FAVPost module are three input dataset as follows:

(1) FAVPost input dataset- contains numerical probability distribution for transient initiating frequency for each transient. Sandia National Laboratory (SNL) provided the probability distributions of the scenario frequency (events per reactor operating year) for all of the transients. The SAPHIRE Version 7 [13] computer code was used to generate the probability distributions (2) initiate.dat - output file generated by FAVPFM as discussed above (3) failure.dat - output file generated by FAVPFM as discussed above The resulting output data of the FAVPost module consists of three output datasets as follows:

(1) user-named FAVPost output dataset - contains results of integrated analysis of all transients, i.e. descriptive statistics for the frequency of crack initiation (FCI), and frequency of vessel 13

failure, also referred to as through-wall crack frequency (TWCF). This file also contains results that allocate FCI and TWCF by transient, RPV major region, and flaw depth.

(2) pdfcpi.out - contains descriptive statistics, including a probability distribution function, (histogram) for the cpi for each transient.

(3) pdfcpf.out - contains descriptive statistics, including a probability distribution function, (histogram) for the CPTWC for each transient.

The material reports (Appendix C) allocate the total FCI and total TWCF to specific RPV major regions.

The allocations are further distinguished between parent and child major regions. There is a discussion of the relationship between parent and child regions on reference 2. For completeness, an excerpt from that discussion is included here as follows:

The discretization and organization of major regions and subregions in the beltline includes a special treatment of weld-fusion lines. These fusion lines can be visualized as approximate boundaries between the weld subregion and its neighboring plate or forging subregions. FAVOR checks for the possibility that the plate subregions adjacent to a weld subregion (termed parent subregions) could have a higher degree of radiation-induced embrittlement than the weld. The irradiated value of RTNDT for the weld parent subregion of interest is compared to the corresponding values of the adjacent (i.e., nearest-neighbor) plate subregions. Each weld subregion will have at most two adjacent plate subregions. The embrittlement-related properties of the most-limiting (either the weld or the adjacent plate subregion with the highest value of irradiated RTNDT) material are used when evaluating the fracture toughness of the weld subregion. A given parent weld subregion will have either itself or an adjacent plate subregion as its child subregion from which it will inherit its chemistry. The flaw orientation, location, size, fast-neutron fluence, and category are not inherited. A parent plate subregion always has itself as a child subregion.
