Dr. J. Nelson Grace Page #2 January 12, 1988 At this time, we are unable to submit the test results and the evaluation thereof. This is because 1) we were unable to complete the overall workload required by this bulletin within the 60-day time allotment; 2) the time required to interface with vendor testing laboratories; and 3) the performance of Charpy Impact Testing on some samples. This latter item, although not specifically required by Compliance Bulletin 87-02, was requested by the NRC Resident Inspectors based upon interpretation of the NRC Temporary Instruction 2500/26 covering the bulletin.

Presently we have completed the mechanical and chemical testing of all samples (except the additional impact testing of the required samples). The status and schedule of the evaluation of the test reaults is detailed in Attacament D.

I declare under penalty of perjury that the statements set forth herein are true and correct to the best of my knowledge.

Attachment A Duke Powr r Company Response to NRC Compliance Bulletin 8 7-02 "Description of the Duke Power Procurement I and Receipt Inspection Program for Fasteners" l j INTRODUCTION The Quality Assurance Procurement Program is based on the following: I a) Review of requisitions and purchase orders by QA personnel b) QA Vendor audits and surveillances of suppliers c) Duke QA releases required prior to shipment d) Review of vendor documentation by QA Vendors e) Receiving inspection by site QA QA REVIEW OF REQUISITIONS AND PURCHASE ORDERS l

All QA Condition purchase orders and requisitions are reviewed by Quality Assurance personnel to assure the appropriate documentation requirements are specified on the purchase orders.

QA VENDOR AUDITS AND SURVEILLANCES During audit / surveillance activities, Duke representatives verify that the vendor has applied applicable sections of their approved quality program to the materials being purchased. examples of audit and surveillance activities are a) Reviewing Certified Material Test Reports (CMTR's);

comparison to ASME Code Section II requirements as applicable.

b) Reviewing heat treat records.

c) Performing dimensional verification.

d) Reviewing audit reports, inspection reports, Nondestructive Examination (NDE) reports, equipment calibration records, and employee qualifications and certification records, ei verifying proper markings.

f) Reviewing the vendor's purchase documents.

g) Verifying that stock materials used were from approved source or (when applicable) properly qualified (eg. , NCA-3 86 7. 4 e) .

h) Verifying acceptance of physical properties such as hardness, tensile, yield, and impact through document review, i) Witnessing manufacturing and testing processes.

4 Attachment A Response To NRC Compliance Bulletin 87-02 Page 2 QA RELEASE BY QA VENDORS In addition to subject audits and surveillances, the vendor is required by each safety related purchase order to receive a Duke QA release prior to shipment, except as exempted per procedure.

When notified by the vendor that an item is ready for shipment, QA Vendors schedules a visit to the vendor or grants a telephone release. We perform surveillances for approximately 10% of the purchase orders. For the other 90%, QA Vendors perform telephone communications to obtain the suf ficient information to grant releases. The QA Vendors Division documents their release on Form QA-605, "QA Vendors Release". Verification of proper marking, proper documentation, and material manufacturer would be addressed as a minimum.

QA REVIEW OF VENDOR DOCUMENTATION Vendor documentation is forwarded to Duke's QA Vendor Division Documentation Section for review. If found acceptable, documentation is approved and forwarded to applicable etations (approval is required and forwarded to applicable stations use) .

The applicable site is notified if problems are noted and material is placed in "HOLD" statues pending satisfactory resolution.

During the review, the following areas are verified:

a) Comparisons to purchase order.

b) Chemical and physical properties reported are compared with applicable material specifications.

c) Assure applicable ASME Code requirements have been included ,

in the certification.

d) Necessary historical and added testing data are included in the documentation package for material qualified per i NCA-3 86 7. 4 (e) .

e) Verify that the material supplier is an approved vendor, l

QA RECEIVING INSPECTION The receiving inspections at Duke's Nuclear sites are performed to I ensure conformance of material to the purchase order. The QA l procedure used for receipt at the site requires the material to be !'

Response To NRC Compliance Bulletin 87-02 Page 3 QA RECEIVING INSPECTION CONTINUED:

All QA condition materials are identified with an unique OA Tag Number in addition to the assigned company number (i.e., MMIS Number). The QA Tag Number is specified to a given purchase order and a single line on that purchase order. This tag is either attached to the item)s .itself or on the packages (s) or container (s). Some items transferred from a Construction Program may not be traceable to purchase orders. In those cases sufficient documentation shall be specified to establish the acceptability of the item.

Response to NRC Compliance Bulletin 87-02 "Description of the Duke Power Controls Used During Storage and Issuance From Stock to Assure the Appropriate Use of Fastener" L

All fasteners are stored in accordance with the requirements of ANSI N45.2.2 Level B or C. procedures in each station's materials manual describe the controls applied for the handling and storage of items (not just fasteners).

Stock fasteners are assigned a company number which facilitates in the retrieval of procurement information in addition to being used in the control of inventories and other company business needs. Non-stock fasteners are not identified by a company number since, in most situations, they are fasteners that are not cornen to other uses or applications.

Fasteners are identified for use normally in one of two ways. First, the Duke Design Engineering Department's piping installation specification (covering flange connections, etc.), hanger installation specification, and various electrical installation specifications are all used in identifying a need for fasteners. The second and most often used method is through each equipment specification and associated instruction manuals, maintenance manuals, and equipment drawings which have bills of material. The majority of fasteners in '

this category would be identified by a manufacturer's part number or by some relationship to the equipment. Much of the information from these documents can ,

be found on data bases. After selection for procurement through one of the methods above, the fastener would be stored and identified as described previously. ,

In addition to the assigned company number, all stock and non-stock QA fasteners are assigned a unique QA tag number. This number is unique to a specific line item on a specific purchase order. For safety-related fasteners, the QA tag number facilitates traceability to the installed location required by 10 CFR 50 Appendix B. The issuance of QA fasteners is controlled by procedures found in each station's materials manual. These fasteners are issued to a work request, which is the Duke administrative program used to control maintenance work '

activities at each station, that identifies and captures all pertinent data such as company and QA tag number, quantities, procedures utilized, and other descriptive information. Although non-QA fasteners are not required to be issued  !

to a work request, in many cases they will be included since the equipment they are used or. is safety-related. Their actual function in those cases, however is not considered safety-related. If fasteners have not been adequately identified l on design documents or data bases and there is a question concerning the proper  ;

fastener, it is the responsibility of the site engineering section to provide (with the help of Design Engineering if needed) the maintenance technician with the correct fastener for that particular application.

Attachment C l

Duke Power Company Response to NRC Bulletin 87-02 Method for Choosina the Fasteners to be Tested.

The selection process began by listing all: 1. Bolts 2. Scraws 3. Studs 4.

Capscrews and 5. Nuts described in the KMIS (Materials Management Information System) computer data files for each station.

l The following factors were used in the selection of test samples.

1. Fasteners listed as standard issue fasteners, not necessarily listed as a part for a specific component, were chosen. In a few cases (especially Oconee), there was not a suitably large selection of general issue fasteners and so the list was supplemented by equipment vendor supplied fasteners.

2. Fasteners that represented an assortment of different materials were chosen. For a reasonable number of fasteners, the description listed the material type.

3. Fasteners that represented an assortment of manufacturers and suppliers were chosen. The MMIS list had very little information on manufacturers and suppliers but the samples chosen took this requirement into account as much as possible.

4. If tensile tests were required (such as safety related bolts), fasteners had to be at least 4 inches long and, if possible, with either 3/8-16 or 3/4-10 threads to accommodate tensile specimen fabrication. To support chemical analysis, the fasteners were at least 3/8 inch nominal size. In some cases, samples were slightly smaller than this. To assure their representation, some safety related fasteners shorter than 4 inches were added to the Non-Safety list. (Testing under bulletin 87-02 is identical for QA and non-QA bolts except for tensile testing.)

A list of forty fasteners was made for each station and presented to each station's NRC resident inspector as a draft from which to begin. The MMIS numbers that begin with "1007", the Construction Department numbering method, are coded for the piping class they are to be used or.. For safety related fasteners the last alpha character is either A, B, or C. The eight or nine digit numbers, Nuclear Production Department numbering method, are safety related if they end with an "N". Non safety related fastener lists contain a number of safety related fasteners because of the reason stated in paragraph 4.

above and because general purpose fasteners are often purchased as safety related to allow a greater versatility of application. Some minor discrepancies were found in the nomenclature of MMIS descriptions. A final i list of fasteners from each station is attached.

McGuire Fastener Sampling On November 25, 1987 Bill orders, NRC Resident Inspector for McGuire, reviewed the list of fasteners and performed an inspection of the fasteners in stock.

I  !

i

Attachment C The NRC Temporary Instructions concerning this bulletin recommended fasteners be added if they had one of nine manufacturer codes or no code. Four examples of this were found and two of them were exchanged with others on the list.

Also found during the inspection was threaded rod which is often issued for making studs. A sample of this was added also. Mr. Orders then reviewed the diversity of materials and manufacturers and agreed that the adjusted sample selection was acceptable. Six samples were replaced on Decemb3r 2, 1987 because the samples originally chosen were out of stock or daleted from stock.

A letter was written to document this adjustment to the line. Other minor list adjustments were made after verbal confirmation with Bill Orders.

For HMIS sequence number 0253580, Sample Numbers MNS/NQ/SCRW/15 and 16, two different manufacturers were found so both were used.

Catawba Fastener Sampling On November 30, 1987 Mark Lesser, NRC Resident Inspector for Catawba, reviewed the list of fasteners, tabulated them by material type, and performed an inspection of the fasteners in stock. Threaded rod was found but not chosen because a storekeeper familiar with fasteners atated that it was not issued very often; also the material types and manufacturers were represented by other bolt samples. Two non-QA bolt samples were chosen and one of them was added to the list. Mr. Lesser then reviewed the diversity of materials and manufacturers and agreed that the adjusted sample selection was acceptable.

Four fasteners were replaced on December 3, 1987 because the samples originally chosen were out of stock or were misnumbered. A letter was written to document this adjustment to the list.

Oconee Fastener Sampling On December 1, 1987 Len Wert NRC Resident Inspector for Oconee and Nick Economos of Region II reviewed the list of fasteners, tabulated them by material type, and performed an inspection of the fasteners in stock. Threaded rod was found and an example was added to the list. Silica Bronze and eye bolt fasteners were removed from the list because they were not of interest to this bulletin. Oconee carries very few standard issue, general purpose fasteners and so most of the fasteners selected were Safety Related and associated with a specific plant purpose. Two materials and manufacturers of nuts were found under MMIS number 1007B3ANIC0B010 and so both were used (samples GNS/QA/ NUT /26 and 27). MMIS number 23210244N was received as a nut and bolt pair so the bolt is sample ONS/QA/ BOLT /5 and the nut is ONS/QA/ NUT /22. Mr. Economos and Mr. Wert both reviewed the diversity of materials and manufacturers and agreed that the adjusted sample selection was acceptable. Len Wert later notified us that MMIS number 1007B1ASICOG007050 was not a Safety Related fastener and it was exchanged for a QA fastener from the non-QA list.

Sample Testing Chemical analysis for all fastener samples was performed by Chicago Spectro Service Laboratory Inc. 4848 South Kedzie Ave. Chicago IL 60632. This company i is an app.oved vendor for providing analytical services under the Duke Power QA l program. Hardness and tensile testing was performed in and under the QA program of the metallurgy laboratory of the Production Support Department of Duke Power Company. It has been proposed that Law Engineering Servic e  !

Charlotte NC perform the Charpy impact property tests. Law Engineering alp l has Duke QA approval for material testing.  !
