Introduction In order to address NRC Bulletin 08 05 as well as Supplements 1 and 2, Houston Lighting & Power Company (HL&P) undertook a comprehensive evaluation in concert with the South Texas Project Electric Generating Station (STPEGS) contractors, other utilities, and the Nuclear Management and Resources Council (NUMARC). The overall effort involved extensive document searches, field walkdowns, extensive field and laboratory testing, nationwide coordination of information, and engineering evaluations of results, i
This report provides a description of the results of that effort for STPEGS Unit 2.
I. Records Review Effort following receipt of the bulletin, the site bulk material heat logs were reviewed to determine which heats of bulk material were manufactured by West Jersey Manufacturing (WJM) or Piping Supplies, Inc. (PSI). That review identified eacq heat of bulk material which was field installed in safety related piping systems. This review revealed that only flange material was supplied in bulk by these manufacturers, in order to substantiate the accuracy of that review, a complete review of installation documentation was performed to identify the specific manufacturer of each flange installed in the plant. This review validated the accuracy of the warehouse heat logs and provided the specific installed location of each WJM/ PSI flange. No Chews Landing material was identified in either review.
To complete the search, a comprehensive review was conducted of vendor component data packages to identify WJM/ PSI materials supplied with those componentr,. This review identified a number of valves, heat exchangers, strainers, and skid mounted piping systems containing WJM/ PSI flanges.
An additional search was conducted for non flange product forms as described in the bulletin ar.d supplements. This review effort concluded that no non flange product forms were supplied to STPEGS by the suspect suppliers.
When completed, the record review effort identified that a total of 158 flanges supplied by WJM or PSI were installed in STPEGS Unit 2.
Two types of flange material were identified - SA105 and SA350/LF2.
Table 1 lists the flanges installed in Unit 2.
All remaining warehouse stock of WJM/ PSI material is on hold pending final resolution of this issue.

II. NUMARC Testing program i
HL&P has participated in the NUMARC generic resolution effort. HL&P has conducted field Equotip tests for each installed flange, ,
supplied to NUMARC a number of WJM/ PSI supplied SA105 flanges from I our warehouse inventory for laboratory analysis, and supplied the ;
data obtained from our records reviews and our field testing for use i in the NUMARC data base, j NUMARC has concluded that the WJM/ PSI material, except for some l
blind flanges (no WJM/ PSI blind flanges are installed at STPEGS),
exhibits the tensile strength and chemical results for product tests -
of the specified ASME Coda material within the typical statistical ;
scatter expected in product tests. NUMARC further concludes that the continued use of these flanges is appropriate for the near and the long term.
The results of STPEGS testing performed to date are boundad by the NUMARC data for material considered by NUMARC to be acceptable for .
use in ASME Code applications. In addition, HL&P has also '
conservatively converted the Equotip Leeb values of installed items ,
to Brinell hardness values (BHN) and, using ASTM methods, estimated i the corresponding ultimate tensile strength for each case with a EHN lower than 137 BHN. The reduced strength was then used to i demonstrate that substantial safety margins exist. ;
Our engineering analyses, as well as analyses by NUMARC, conclude that there is no technical concern with high hardness readings as L there is no upper limit on strength for SA105 materials. In the case of STPEGS, the chemical analyses performed to date are within :
the actual Code specification limits and no weldability problems f have been experienced. The products are of small sizes, with ;
nominal thickness of 5/8 inches or less in all cases, for which the Code imposes no fracture toughness requirements.
A concern developed with an apparent pattern of consistently high [
hardness readings on one heat of SA350/LF2 material (heat number !
1705), but additional warehouse and laboratory hardness tests on i cross sectioned flanges of this heat showed acceptable hardness i across the entire volume of the flange and on the flange face. The high hardness readings in the field were determined to be due to a surface hardness condition on the shoulder of the flange (the only accessible surface for field testing). The surface hardening is as a result of quenching and terpering operations.
Table 2 displays the test results for each heat of material installed in Unit 2. Field Equotip, laboratory chemistry, and laboratory mechanical testing data are shown. Additional testing, currently in progress, is denoted by an asterisk (**).
Table 3 displays the results of the stress evaluations for flanges with field hardness below 137 BHN converted from Equotip readings.

I!!. Additional Testing to be Performed Although HL&P is satisfied that tests conducted to date sufficiently demonstrate the adequacy of materials installed in Unit 2, additional testing will be serformed in order to provide the NRC with additional data. The sasis for the additional testing is categorized by the following types of material:
A. ASME SA105 Field Installed Flanges Six (6) different heats of material are installed.
At least one piece from each heat has been laboratory tested (12 pieces total).
- Each piece has been fleid hardness tested.
Additional laboratory chemical analyses will be performed on randomly selected warehouse specimens from the 6 heats in order to obtain a total lab test quantity similar in sample size to that of a typically utilized sampling program. In this case the sample size selected was 53, leaving 41 specimens to be tested, the 12 previously tested will comprise part of the total sample.
B. ASME SA105 Vendor Installed Flanges Nine (9) different heats are installed - one heat is common to one of the field installed heats.
Of the other 0 heats, 4 have acceptable field Equotip test results and the remaining 4 have at least one flange outside the 137 187 BHN range.
In order to maintain the integrity of the installed flanges to the maximum extent, but to obtain additional confidence in the adequacy of the material, HL&P is performing chemical analysis on filings removed from the shoulder of 6 flanges whose Equotip test results are outside the specification hardness range. These 6 samples represent the four heats which have flanges outside the 137 187 BHN range.
C. ASME SA350/LF2 Field Installed Flanges Four (4) heats are installed, One (1) heat was laboratory tested as SA105 material (T!.is heat was certified as both SA105 and SA350 material).
One (1) heat (1705) was laboratory tested for hardness and found satisfactory.
In order to provide additional confidence HL&P is performing additional laboratory chemical and mechanical analyses on one flange from each of the 4 heats.
A5 Rev. O
i IV. Conclusion The results of STP testing performed to date are bounded by the NUMARC data for material considered by NUMARC to be acceptable for uso in ASME applications. The results of the field testing and laboratory analyses are either within the ASME material specification range or within the range of expected deviation for a product test versus a heat test. From a design standpoint, HL&P has also performed a conservative stress analysis of flanges with hardness below a converted 137 CHN. In addition. HL&P has evaluated the cases of reported high hardness and have concluded that there is no technical or safety concern.
Any deviation from ASME specification limits determined from the additional testing being conducted will be similarly evaluated.
HL&P therefore concludes that the subject flanges installed in STPEGS Unit 2 are fully acceptsble for use in ASME piping systems and components ano no further action is required.
