l APPENDIX A Nuclear Assurance Corporation Docket No. 99900383/87-01 NOTICE OF NONCONFORMANCE This NRC inspection was made to follow-up on allegations concerning a gage that was used to perform a pressure test on the Nuclear Assurance Corporation (NAC)

Cask NAC-IE at Sandia National Laboratories in New Mexico. Certificate of Compliance (C of C) Number 9183, Revision 4, dated July 30, 1986, requires that the Model NAC-1 shipping package (cask) be fabricated in accordance with the information and specifications contained in the application for cask certification. NAC's application to the NRC was dated July 9,1986 and supple-mented on July 24, 1986. C of C 9183 requires, in part, that the packaging be constructed in accordance with Nuclear Fuel Services, Inc. (NFS), Drawing No. E10080, sheets 1 through 4, Revision 21, as modified by the NAC letter dated July 24, 1986. The Model NAC-1 shipping package includes NAC casks IA, IB, IC, 10, and IE and Nuclear Fuel Services (NFS) casks 4A and 48. All casks are owned by NAC and covered by NRC C of C 9183, Revision 4 The general license provisions of 10 CFR 71.12 apply to NAC-1. NAC has a Quality assurance (0A) program approved by NRC as satisfying the provisions of Subpart H of 10 CFR 71. Based on the results of this inspection conducted on February 23-27 and March 24, 1987, it appears that certain of your activities were not conducted in accordance with either C of C 9183, Revision 4 or the NAC OA program. These items are set forth below.

1. C of C 9183, Revision 4, requires that a 30 psig pressure test be performed on the 0-ring seals of the NAC-1 cask prior to each shipment.

Paragraph 71.125 of Subpart H of 10 CFR 71 " Control of measuring and test equipment," requires, in part, that gages used in affecting quality are properly controlled to maintain accuracy within necessary limits.

Contrary to the above, a pressure gage used to perform the 30 psig test on cask NAC-1E was not calibrated for use over the range 0 to

~!0 psig, and would not indicate pressures greater than 12 psig because the spring installed internal to the gage that resisted movement of the pninter above 10 psig was misadjusted and at 35 psio the gage indicated 12 psig. (87-01-01)

2. C of C 9183, Revision 4, requires that a 30 psig pressure test be performed on the 0-ring seals on the NAC-1 cask prior to each shipment.

8704170356 870410 PDR GA999 EECNAC 99900383 PDR

Contrary to the above, the 30 psig pressure test of the 0-ring seals on the NAC-1E cask at Sandia failed the pressure drop requirement of C of C 9183 and following corrective action the test was not l repeated before shipment. (87-01-02)

3. C of C 9183, Revision 4, and NFS drawings E10080 sheets 1 through 4, Revision 21, require that the cask lid of the NAC-1 cask be sealed with 0-rings which are compressed by bolts.

Contrary to the above, the lid was welded to the NAC-1E cask because the 0-ring seals failed the 30 psig pressure test. (87-01-03)

4. Section 5.1 of NAC procedure 155, " Measuring Equipment Calibration and Records," Revision 4. dated March 1982, requires, in part, that the location of all equipment be listed on the Equipment Calibration Log (ECL).

Contrary to the above, the location of hydrostatic test gace P-1011 was listed on the ECL as being in the NAC office but the gage was physically missing. (87-01-04)

5. Section 5.5 of NAC 155, Revision 4, requires, in part, that all equipment be listed on the ECL.

Contrary to the above, a dial indicator identified by serial number GT-41 was not listed on the ECL. (87-01-05)

6. Sections 9.3, 9.4, and 9.5 of NAC 155, Revision 4, requires, in part, that micrometers and dial indicators be calibrated at intervals of 25, 50, 75, and 100% of full scale.

Contrary to the above, the calibration of six microneters and three dial indicators was not performed at the intervals specified. (87-01-06)

7. Section 9.2 of NAC 155, Revision 4, requires, in part, that the Cali-bration Certification Report (CCR) contain the calibration standard identification number, noun name or abbreviation, manufacturer, make, riodel and serial number, and last date of calibration for the actual piece of measuring or test equipment used for the calibration.

Contrary to the above, the NRC inspectors did not find any CCR from outside vendors performing calibrations that contained this information.

(87-01-07)

8. C of C 9183, Revision 4, requires that the cavity relief valve be tested annually at the setpoint for each NAC-1 cask.

Section 4.2.8 of NAC procedure 532, "NAC-1 Cask Annual Institute of Nuclear Energy Research (INER) Maintenance Procedure," Revision 1, dated July,1985, requires that the relief valve release at 200 10 psig.

Contrary to the above, the 1986 annual maintenance reports for casks NAC-10, NAC-1C, NFS-4A, and NFS-4B contain no information as to whether or not the cavity relief valve tests were performed. (87-01-08)

9. Section 6.14 of NAC 532, Revision 1, requires that a torque wrench be used to tighten the assembly nut to 10 ft-lb (+5,-0) and Section 2.0 of NRC 532, Revision I requires 20 ft-pound and 1500 ft-pound torque wrenches.

Contrary to the above, a 0-1000 ft-lb torque wrench was used for the 1986 annual maintenance of the NAC-1A and IE casks. This wrench could not indicate 10 ft-lb with a minimum graduation of 20 ft-lb. (87-01-09)

10. Section 4.2.2 of NAC 532, Revision 1, requires relief valves to be replaced annually and the serial number of the replacement cavity relief valve be recorded on the AM report.

Contrary to the above, the serial numbers of the replacement cavity relief valves were not recorded on the 1986 AM reports for casks NAC 1A, IC, and ID and NFS 4A and 4B and the 1987 AM report for cask NAC-1E.

(87-01-10)

11. The AM report form attached to NAC 532, Revision 1, requires that the manufacturer's name, serial number, device range, calibration date, and calibrator's name be documented in Section 4.0 for the torque wrenches used for the AM of casks.

Contrary to the above, Section 4 was left blank on the 1986 AM reports for casks 4A, 4B, 1D, and 1C relative to torque wrench information.

(87-01-11)

12. Paragraph 1.7 of Section 18.1 of the NAC Ouality Assurance Manual (OAM) requires that external audits be performed on the basis of importance l

and complexity of service.

Contrary to the above, NAC did not perform an audit at the Precision Instrument Company where NAC measuring and test equipment was calibrated.
