VIOLATIONS:
None 8.
NONC0l!FORMANCES:
1.
Contrary to Criterion V of Appendix B to 10 CFR Part 50 and paragraph 2.6.1 of Section 15 in the Quality Assurance Manual, six steam generator tube sleeves (Serial Nos. J-6-7-28, K-13-7-28, J-13-3-28, J-14-10-28, K-13-1-28, and H-12-1-36) were found in the store room with neither a reject nor a hold tag although Contract Variation Approval Requests Nos. SC-095 and SC-098 had rejected these sleeves.
2.
Contrary to Criterion V of Appendix B to 10 CFR Part 50 and paragraph 1.0 of Section 14 in the Quality Assurance Manual, one lot of guide tube upper nuts whose identity was unknown was found without a route card although this lot was at three different machining operations and locations within the shop. As a result, ready determination of the status of the parts could not be accomplished.
C.
LINRESOLVED ITEMS:
None D.
STATUS OF PREVIOUS INSPECTION FINDINGS:
(Closed) Nonconformance (82-01): The formal canvass of document recipients has not been performed at least in the last year.
The procedure has been revised to include a form to document the canvassing.
The canvassing of the last quarter of 1982 was reviewed. No further significant problems were identified in this area although it was noted that the records of canvassing for the first quarter of 1982 were misfiled and the last quarter was performed behind schedule.
E.
OTHER FINDINGS OR COMMENTS:
i 1.
gnconformances and Corrective Actions - The procedures established for control of nonconformances and corrective actions were reviewed. The status of materials, parts, and assemblies in the shop was inspected.
Parts found to be nonconforming were reviewed to verify implementation of the QA program in regard to identification and disposition of
ORGANIZATION: BABC0CK & WILC0X COMPANY NUCLEAR FUEL SERVICES LYNCHBURG, VIRGINIA REPORT INSPECTION NO.:
99900001/83-01 RESULTS:
) AGE 3 of 4 nonconformances on Component Discrepancy Reports and Contract Variation Approval Requests. The sumaries of corrective actions and the corrective actfon meeting reports were inspected.
In this area of the inspection, nonconformance A was identified on the failure to tag rejected steam generator tube sleeves. Babcock & Wilcox (B&W) properly tagged the sleeves in question prior to the end of the inspection. Nonconformance B was identified on the failure to have a route card issued on parts inprocess.
It was noted that manufacturing procedure MA-1207 expanded the QA manual requirement in regard to having routa cards accompany parts through the plant.
It was additionally noted that the absence of route cards also could result in the loss of traceability information. B&W issued a route card for the lot of material in question before the end of the inspection.
2.
Hydrogen Controls - The hydrogen controls, namely moisture measurements, of AL 0, B C poison pellets were inspected. The drying and testing of 7
a current 18t of pellets in production were reviewed. The sampling, analytical method, and use of calibrated equipment were verified. The drying procedure and ovens were inspected for Lot No. I.
3.
Pellet Attributes - The vendor supplied data and B&W receiving inspection of the pellets for two current projects were inspected (97H and 20G).
The pellet specification and drawing were reviewed and it was verified that design requirements had been checked. The use of approved visual standards, calibrated tools, and compliance to the procedures and specification were verified.
4.
Pellet Enrichment and Impurities Controls - The pellet chemistry records and overchecks of the same pellet lots above were inspected. The conformance to specification and procedure requirements was verified.
The use of approved procedures by the vendor and the overcheck lab was verified.
It was noted that there is a specification requirement on the soluble or free carbon content. The reports by the vendor and the overcheck lab were significantly different. One reported soluble I
or free carbon at approximately 30% of the specification limit and y
the other at 5% of the limit. A review of the analytical methods 2
found differences in the test temperatures between the two methods.
The lower temperature was associated with the higher results (30% of the limit). The higher temperature yielded raw data that was higher (50% of the limit) than the lower test temperature. The raw data was corrected for the carbon associated with the known baron as B C under 4
the assumption that the higher temperature broke down the B C and 4
thereby the resultant was lower (5% of the limit). The NRC inspector questioned the correctness of the test temperatures used.

99900001/83-01 RESULTS:
) AGE 4 of 4 appear that the lower temperature may be too high or the higher temperature too low or both. This question will be reviewed during a future inspection of the Utility Power Generation Division which approved both of these procedures and wrote the specification.
5.
General Information - B&W is expanding its machining, welding, and heat treatment operations at the Commercial Nuclear Fuel Plant. This activity will supplement fuel fabrication from mid 1983 to late 1983.
Steam generator tube sleeves are a current product line and incore detectors and quick vent closures for drive mechanisms are planned for the near future.
