Subject:
Limerick Generating Station (LGS) Unit 1 NRC Bulletin No. 88-05, Supplement 1 "Nonconfonning Material Supp11ed by Piping Supplies, Inc.
at Folscm, New Jersey and West Jersey Marufacturing Ccrrpany at Williamstown, New Jersey"
Dear Mr. Rossi:
The subject supplement to the Bulletin 88-05, received by Philadelphia Electric Ccmpany on June 22, 1988, requires that ilcensees and construction pennit holders review purchasing records for t
presence of Piping Supplies, Inc. (PSI) and West Jersey Manufacturing Ccrnpany (WJM) supplied materials and ccrimence appropriate testing to determine acceptability of suspect materials.
In response to the Supplement 1 to the Bulletin, Philadelphia Electric Conpany (PECo) has reviewed purchase records for Limerick r
Generating Station to detennine the presence of material frcm PSI and l
WJM. We have determined that suspect material has been received at Limerick Generatlng Station. Upon discovery of the suspect traterial, those ccriponents determined to be in the warehouse were Ininediately segregated and placed on hold. Those ccmponents which are determined to be Installed and accessible in safety related systems will be l
expeditiously tested to assure acceptability In accordance with the l
testing program ed dispositioned as outilnad below.
The subject wpplement delineated speelfic actions to be f
undertaken by the IIcensees. To assure clarity, these actions are restated below along with PECo response to each of those items.
{
1.
Action Requested Review purchasing records to determine whether any PSI or WJM
[*
suppiled ASME Code or ASTM material has been furnished.
Supplement I reduced the scope frcm "materials" to "fittings and flanges".
This review should be init;ated and ccmpleted prcmptly.

Response
We have nearly ccmpleted our review of purchase records for fittings and flances which may have been purchased frcm PSI & WJM in the form of a bulk purchase or which would have been part of a piping subassently.
Approximately 4000 suspect ccmponents were Identified frcm purchase records. Most of the suspect ccumonents were still stored in the warehouse. As of July 20, 1988, we have determined that 202 suspect ccrmonents have been identified as installed in ASME Section 111 Systems in LGS Unit 1.
The LGS Unit 2 search is ongoing.
2.
Actlon Requested For ASME Code and ASTM materials furnished by PSI or WJM that are either not yet installed in safety-related systans at your facility or are Installed in safety-related systems of plants under construction, the following actions are requested: (perform w lon a and either action b or c).
a.
Provide a IIst of WJM and PSI supplied materials that are found not to be in conformance with the applicable code requirements or procurement specifications and identify the appilcations in wt 3ch these materials are used or will be used.
Include the nuterial specification, the nature of the ccrmonent (e.g., p pe flange), size and pressure rating; also indicate the ( Tain of purchase, and olther, b.
Take actions that provide assurarce that all received nuterials ccmply with ASME Code Section III, ASTM, and applicable procurement specification requirements, or that danonstrate that such materials are suitable for the Intended service. For example, this program should include specifl; verification that austenttic stainless steels have been received in a non-sensitized condition, or, c.
Replace all questionable fittings and flanges with materials that have been nunufactured in full ccmpilance with ASME Code Section III, ASTM, and the appilcable procurement specification requirements.
Supplement 1 reduced the scope of the review f rcm "materials" to "fi tt ings anc' fl anges".
Response
2a.
In conjunction with nut %RC, we are currently developing a nuterial database for PSI and WJM supplied fittings and flanges. The data base will include sweral fields designating rnaterial specifications, nature of ccmponent, size, pressure rating and chain of purchase. The generic format of the rnaterial database was developed by NWARC for rnanber ut i 1 I t ies. Upon ecmpletion of the docurent roview, the requested Information will be sinultaneously tranunttted to the NRC and to nut %RC. We will determine the conformance of the suspect corponent to the appilcable codes via the testing program.
2b. We have developed a testing program to assure conformance of suspect material to the applicable codes or to determine acceptability of the suspect rnatorial using several generic Industry guidelines for testing developed by Nu%RC. Our testing program is a well docunented, quality controlled program which incorporates appropriate controls, check points, data doctmentation, training of personnel and other guidelines established by tu%RC. Additionally, a testing databave has been established per NUPARC guidelines. As results of the testing becane available, the Information will be transmitted to the NRC and to NUMARC.
The testing program will Initially focus on Installed, accessible safety related ccmponents. Hcwever, to assure adequacy of the testing procedure some testing has aircady been conducted on several warehouse flanges. Details of the testing are given in the response to item 3, below.
2c.
PECo will not install corponents which are suspect in LGS Units 1 and 2.
As noted above, a hold was prcmptly placed on all suspect ccmponents. Further, the rnaterial which cannot be determined as adequate to perfonn its required function will be replaced.
3.
Action Requested For ASME Code and ASTM materials furnished by WJM or PSI already installed in safety-related systems in operating plants, the folicwing actions are requested:
a.
Provide a list of the WJM and PSI supplied materials that are found not to be in conformance with the appilcable ccde requirements or procuranent specifications and identify the appilcations in which the materials are used.
Include the material specification, the nature of the carponent (e.g.,
pipe flange), size, and pressure rating; also indicate the chain of purchase.
1 4
b.
Take actions requested in 2b or 2c above. However, an evaluation should be undertaken prior to replacing questionable material in accordance w!th 2c above that considers the occupational radiation exposure that would be received during the replacament process. This evaluation should be considered in develoolng the method and timing of material replacements.
c.
Docunent and maintain for inspection a basis for continued plant operation if the program requested in item 3b has not been completed within 120 days of the date of receipt of this bulletin.
Supplanent I reduced the scope of paragraph 3 of Bulletin 88-08 l
frcm ASME and ASTM "materials" to ASME and ASTM "flanges and fittings".
For-ASME tod ASTM flanges and fittings furnished by PSI and WJM already Installed in safety-related systems in i
l operating plants, the following actions are requested by i
Supplement l'
\\
a.
Conmence appropriate testing of accessible flanges and fittings prcmptly to identify confonnance of materials to l
ASME and ASTM material specifications.
Test results for l
flanges and fittings reported to be frcm the same heat i
4 should be ccmpared for consistency and for confonnance to the ASME/ ASTM specifications and to values listed on i
material CMTRs. Any devlation frcm the specification requires an appropriate analysls justifying continued operation, j
b.
If any inaccessible flanges or fittings are Identified, an analysis trust be perfonned Justifying continued operation, i
j c.
All other provisions of paragraph 3 of Bulletin 88-05 remain in effeet.
l d
Response
B 3a. As stated in item 2 above, we are developing a list of suspect materials. The conformance of suspect materials to the appilcable material codes can be determined via the j
testing progran. Thus far, we have developed and will be implementing a well defined, quality controlled progr6m for testing of suspect materlal in accordance with existing internal PECo procederes and newly deseloped NV %RC generic q
testing guidelines. The testing program will be revised as necessary upon receipt of further NRC or t& ARC guidellnes.
Provisions exist within the established testing database to make the necessary ccmparisons requested by the NRC.

5-Due to the large nunber of items we cannot comlete testing within the time frame estabilshed by Supplement 1.
We are proceeding with haste to perfonn this testing. However, the need to perform the program in an orderly and controlled fashion places limitations on the rate of testing. A schedule for 100% testing of installed, accessible safety related flanges and fittings is expected to be available by August 1, 1988.
As mentioned earlier, we have cumleted hardness testing on 37 canponents found in the warehouse. The results of the testing are attached in Table 1.
3b. We have Identifled two inaccessible flanges in the spray pond (NRC Notification Nurber LGS 1-88-05-01). A JustIfIcatton for continued operation is being developed for those flanges.
Additionally, we are working with NUMARC on developing a generic methodology for Justifying continued operation. As suspect flanges are Identified as inaccessible, we will notify the NRC within the allocated time frarre and will develop justification for continued operation (JCO).
3c. As requested, JCO's will be developed and maintained for inspec:,lon.
4.
Action Requested For any PSI and WJM supplied materials having suspect CMTRs and used in systans that are not safety-related, take actions camensurate with the function to be performed.
Supplement 1 provides further instructions.
For flanges and fittings already identified as having been supplied by PSI or WJM, the actions requested in 3c and 3d above are to be canpleted within 30 days of receipt of the supplement.
For flanges and fittings identified after receipt of this suppicment, the actions requested in 3a and 3b above are to be camleted within 30 days of identifying the flanges cr fittings as being supplied by PSI and WJM.
Response
As noted in the response to Paragraph 3 above, we cannot canplete the testing within the time period established by Supplanent 1.
The In-situ testing is to begin within the next few days in accordance with the schedule noted in 3a above.
5.
Action Requested Addressees are requested to retain nonconfonning notorials untl1 advised further by the NRC. Nonconforming materials should be segregated to ensure that they are not inadvertently used.
Response
We have segregated and retained the suspect materials as requested above.
6.
Action Requested For operating plants, all scheduled actions should be conpleted before a restart from the next. W outage start.Ing after 180
'is bulletin.
For plants under days from the dat's of receipt construction all scheduled act-2nd the reporting required by 2 below should be ccmpleted prloc w the planned fuel load date.
If any addressee cannot meet this schedule, they should justify to the NRC their proposed alternative schedule.
Supplenent 1 further Instructs:
Addresses are encouraged to report the results of tests
.)
e and WJM supplied flanges and fittings to the INPO Nuclear sork for discussion to the Industry.
Response
As noted earlier, the material and test results are being sent to tO%RC via the INPO Nuclear Network. A written response to the subject NRC Bulletin will be flied with the NRC within 120 days of receipt of the Bulletin.
SuTmary of Responses Philadelphia Electr8, "oupany is conducting 100% review of purchasing docenentation and installation records to detenmine the presence and status of PSI and WJM naterial. A testing program developed in accordance with NtfMRC guidelines is being irrplemented.
