Response to NRC Bulletin No. 88-05 and Supplements 1 and 2 Gentlemen:
References (b) and (c) requested that licensees take certata actions and submit information regarding materials supplied by Piping Supplies, Incorporated (PSI) at Folsom, New Jersey and Hest Jersey Manufacturing Company (HJM) at Williamstown, New Jersey.
Reference (d) suspended, temporarily, most requirements of References (b) and (c) for plants with full power operating licenses.
Maine Yankee has conducted a review of appropriate records and testing as requested by References (b) and (c). As of August 3,1988, the date of Reference (d), two items were found to have been provided, indirectly, by HJH. An inconsequential deviation from the applicable specification (elongation) was reported to the NRC Operations Center, as required by Reporting Requirement 1 of Reference (c), on July 13, 1988. One of the two l
items is installed; we have evaluated the application of this item and l
conclude that it is suitable for the intended service.
Attcchment A repeats each action requested by reference (b) as modified by Reference (c).
The Maine Yankee response is provided following each item.

MaineYankee ATTACHMENT A ACTIONS REQUESTED AND HAINE YANKEE RESPONSE ACTION ITEM 1:
Review purchasing records for your facility and determine whether any HJH-or PSI-supplied ASME Code or ASTM materials have been furnished to your facility.
The lists of purchasing and receiving companies given in Attachments 1 and 2 (of Reference (b),Bulletin 88-05) have been developed through the NRC's partial review of PSI and HJM documents.
It is emphasized that the NRC has not reviewed all documents; therefore, the review of records should not be limited to the companies on these lists.
The records review for PSI-supplied material should cover the period since January 1, 1985. The HJH review should cover the period since January 1, 1976.
SUPPLEMENT 1 ADDITION:
Review of purchasing records may be reduced in scope from ASME and ASTM "materials" to ASME and ASTH "fittings and flanges" and the review should be initiated and completed promptly.
(Based on the discovery by CP&L of nonconforming flanges and on NRC review of records of HJH's production of numerous flanges purportedly from Heat No. 7218, licensees should specifically be alert to identify records for flanges from Heat No. 7218).
Maine Yankee Response:
A review of Purchasing records revealed no indication of any direct orders placed with PSI or HJM.
A search of all Stores records back to 1976 involved approximately three man months of effort. All documentation associated with orders for fittings, flanges, valves, and pumps (known te ave been furnished with flanges or fittings) were reviewed in an effort to establish a link to PSI or HJM.
No records (CHTR's, C of C, etc.) were discovered that bear the l
names of PSI or HJM with the exception of one purchase order to Now i
Hampshire Yankee for two blind flanges; these flanges had been supplied I
indirectly from HJH.
Toward the end of the investigation, additional information was received that implicated Chew's I.anding and Philadelphia Steel.
Inquiry was made immediately of the persons conducting this investigation to determine if the names of those companies had been seen during the filo search.
Although they had not been looking specifically for these two supplemental targets, they had high confidence those names had not appeared on material documentation.

r MaineYankee ATTACHHENT A ACTION ITEM 2:
For ASME Code and ASTM materials furnished by PSI or HJH that are either not yet installed in safety-related systems at your facility or are installed in safety-related systems of plants under construction, the following actions are requested:
(perform action a and either action b or C) a.
Provide a list of HJH-and PSI-supplied materials that are found not to be in conformance with the applicable code requirements or procurement specifications and identify the applications in which these materials are used or will be used.
Include the material specification, the nature of the component (e.g., pipe flange), size and pressure rating; also indicate the chain of purchase, and either b.
Take actions that provide assurance that all received materials comply with ASME Code Section III, ASTH, and applicable procurement specification requirements, or that demonstrate that such materials are suitable for the intended service.
For example, this program should include specific verification that austenitic stainless steels have been received in a non-sensitized condition, or, c.
Replace all questionable fittings and flanges with materials that have been manufactured in full compliance with ASHE Code Section III, ASTH, and the applicable procurement specification requirements.
SUPPLEMENT 1 ADDITIO1:
The scope of paragraph 2 of Bulletin 88-05 is reduced from ASME and ASTM "materials" to ASME and ASTM "flanges and fittings." All other provisions of paragraph 2 of Bulletin 88-05 remain in effect.
Maine Yankee Response:
One of the two HJH-supplied items was not yet installed.
a.
The item was procured for use in the Demineralized Hater Storage Tank but subsequently not used and returned to stock for safety class use.
The item was an ASTM A105 8" 150# raised face blind flange.
The chain of purchase of the item was:
Sold to Guyon Alloys Inc. by HJM on Guyon P.O. A72101-NH.
Sold to Dravo Corp. by Guyon on Dravo P.O. #E2936-471.
Sold to New Hampshire Yankee by Dravo on United Engineers and Constructors (UE&C) P.O. #248-1.
Sold to Maine Yankee by New Hampshire Yankee on H.Y. P.O. #46635.
b.
Not applicable (See c., below).
c.
The item was rendered unusable by cutting out a sample for testing.
Test results are documented in Attachment B.
0323L-RCC
e MaineYankee ATTACHMENT A ACTION ITEM 3:
For ASHE Code and ASTH materials furnished by HJH or PSI already installed in safety-related systems in operating plants, the following actions are requested:
a.
Provide a list of the HJH-and PSI-supplied materials that are found not to be in conformance with the applicable code requirements or procurement specifications and identify the applications in which the materials are used.
Include the material specification, the nature of the component (e.g., pipe flange), size, and pressure rating; also indicate the chain of purchase.
b.
Take actions requested in 2b or 2c above. However, an evaluation should be undertaken prior to replacing questionable material in accordance with 2c above that considers the occupational radiation exposure that would be received during the replacement process.
This evaluation should be considered in developing the method and timing of material replacements, c.
Document 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.
SUPPLEMENT 1 ADDITION:
The scope of paragraph 3 of Bulletin 88-05 is reduced from ASME and ASTM "materials" to ASME and ASTM "flanges and fittings."
For ASME and ASTH flanges and fittings furnished by PSI or HJM already installed in safety-related systems in operating plants, the following actions are requested:
a.
Comnence appropriate testing of accessible flanges and fittings promptly to identify conformance of materials to ASHE and ASTH material specifications.
Test results for flanges and fittings reported to be from the same heat should be compared for consistency and for conformance to the ASME/ ASTM specifications and to values listed on material CMTRs. Any deviation from the specification requires an appropriate analysis justifying continued operation, b.
If any inaccessible flanges or fittings are identified, an analysis must be performed justifying continued operation.
c.
All other provisions of paragraph 3 of Bulletin 88-05 remain in effect.
i 0323L-RCC
MaineYankee ATTACHMENT A Maine Yankee Response:
One of the two HJM supplied items is installed on the Demineralized Hater Storage Tank (DHST) level alarm tank connection, which is a Safety Class Three application, a.
The item is an ASTM A105 8" 150# flat face blind flange.
The chain of purchase is the same as listed in response to Item 2.a., above, b.
To comply with Action Item 2.b., testing of this item and of the non-installed flange was conducted to determine conformance to specifications.
Because this item could not be removed from service without shutting the plant down and draining the DHST, a fell tensile specimen could not be obtained; however, a small sample was obtained and tested for chemistry and hardness.
Because the hardness and chemical composition of the two parts were found to be similar and the heat numbers are the same and from a small mill batch, it was concluded that the mechanical properties are also similar.
Test results are provided in Attachment B.
Based on our review of CMTRs and independent test results, we have found that only the elongation reading is slightly out of specification (20.9% vs. 22% minimum).
He have evaluated the application of this item and conclude that it is suitable for the intenfed service. Under the operating and design conditions for this application, the flange installation well exceeds the safety factors required by the applicable design codes.
The item will not be l
replaced (therefore Action Item 2.c., for the installed item, is not applicable).
c.
The program requested in Action Item 3.b. was completed July 13, 1988, within 120 days of the date of receipt of this bulletin.
l Therefore, no action is required in response to this Action Item, 3.c.
In response to Supplement 1. Addition a, appropriate testing of the installed item was performed.
Results are provided in Attachment B.
An appropriate analysis justifying continued operation was performed, as a result of the slightly out of specification elongation reading.
This analysis has been filed with the Maine Yankee Purchase Order for the materials.
In response to Supplement 1, Addition b, the only installed item was accessible and this action is, therefore, not applicable to Haine Yankee.

MaineYankee ATTACHMENT A ACTION ITEM 5:
Maintain for inspection the documentation of the specific actions taken for the identified materials.
SUPPLEMENT 1 ADDITION:
Addressees are requested to retain nonconforming materials until advised further by the NRC. Nonconforming materials should be segregated to ensure that they are not inadvertently used.
Maine Yankee Response:
Documentation of the specific actions taken for the identified materials has been filed with the Maine Yankee Purchase Order for the materials.
The installed flange has been determined acceptable for use and remains installed.
The remaining flange was rendered unusable by cutting out a sample for testing.
This will be retained pending further direction from NRC or until August 31, 1989 whichever is earlier.
