Subject:
Additional Information for Response to Complic a.e Bulletin 87-02
Dear Sir:
In Reference (c), Yankee Atomic Electric Company's (YAEC's) i tsponse to Reference (b), we stated that we would provide the following addit anal information for Action Items 5 and 6 by March 11, 1988. The inforu tion to be provided is es follows:
(a) results of proof load testing and safety significance and limits of application of out-of-tolerance nuts ( Action Item 5); (b) results of testing of additional fasteners from the vendor who supplied the out-of-tolerance nuts (Action Item 5); and (c) procedure revision for procurement, receipt inspection, and testing based on the results of testing done for Reference (b) (Action Item 6).
This letter provides the three items of information.
(a) Out-of-Tolerance Nu_t_ss In Reference (c), one safety-related nut was identified as not meeting the requirements of ASTM A194 (Sample No. YR-87-02-16SR-N).
l The nut was found to have a carbon content less than the minimum j
- required, i
(
Since carbon content will primarily affect strength, prcof load testing has been done for two nuts (Sample Nos. YR-87-02-27SR-N and YR-87-02-28SR-N) selected from the same heat number as the out-of-tolerance nut identified in Reference (c).
Data for these nuts are contained in Attachment 1.
Proof load testing was performed in accordance with ASTM A370, Supplement III, Paragraph S14.1.
Proof loads were obtained from I

PDR ADOCK 05000029 O
United States Nuclear Regulatory Commission March 7, 1988 Page 2 FYR 88-31 Table 3 of ASTM A194. Additionally, chemical and hardness testing of the nuts was performed in accordance with ASTM A370.
Test Results: The two nuts met all the chemical and hardness requirements of ASTM A194 with the exception of carbon content.
In both cases, the carbon content was less than the minimum required
(.32 and.31 versus.40 1 03 minimum).
A proof load of 9,170 lbs as required by Table 3 of ASTM A194 was applied to each nut. Both nuts were able to recist the proof load d.th no stripping of the threads observed. Test results are summarized in Table 1 of Attachment 2.
Safety Significance and Limits of Application:
Based on the results of the proof load tests, the 5/16-18 nuts with low carbon content will be able to develop the full strength of any 5/16-18 fastener appropriate for use with A194, Grade 2H, nuts. Therefore, the low carbon content of these nuts has no safety significance and places no limits on the use of these nuts.
(b) Additional Fastener Testing In order to determine the extent of nonconforming fasteners from the vendor who supplied the out-of-tolerance 5/16-18 A194 2H nut, samples from additional lots supplied by the vendor were subject to testing (Sample Nos. YR-87-02-22SR-N, YR-87-02-24SR-N, YR-87-02-25SR-N, and YR-87-02-26SR-N).
The four nuts were tested for chemical compcsition end hardness in accordance with ASTM Specification A194 2H.
Spacific fastoner data is provided in.
Test Results: All four nuts met the chemical and hardness requirements of ASTM A194 2H.
Actual test results are summarized in Table 2.
(c) Action Item 6 - Further Actions Based upon the _sults of the fastener testing and the review of current plant procedures, additional changes are being made to the receipt inspection process.
j Plant Procedure AP-0212, "Control of Purchased Material Equipment, and Services, is being revised to include random sampling and testing of safety-related fasteners to ensure compliance with the applicable material specification.
These measures will provide additicnol assurance that fasteners used in the plant meet the requisite specifications and requirements and that the operability of safety-related plant components is not affected.
