Nn . QQQnn7Ad/n7-n1 RFSUITS? pAGF 1 nf A E. INSPECTION FINDINGS AND OTHER COMMENTS:
- 1. Entrance and Exit Meetings SSM management representatives were inforn,ed of the scope of the inspection during the entrance meeting. The inspection findings and observations were summarized during the exit meeting on March 19, 1987.
- 2. Procurement The NRC inspector examined SSM procurement documents represeriting orders to suppliers of tube shells and hollows which are the starting material for the fabrication of fuel cladding. This examination revealed that the requirements of 10 CFR 21 have been imposed on suppliers of shells and hollows since the last
,NRC inspection.
Review of SSM-1030. " Tube Reduced Extrusions (TREX) - Zirconium Alloy," Revision 9, dated February 16, 1983, confinned the quality requirements for hollows that were imposed on suppliers.
The NRC inspector determined that the documentation required by SSM-1030 for several orders was in compliance with SSM-1030 Revision 9. The suppliers used for these purchases were approved in accordance with SSM procedures.
- 3. Inspection of Starting Material The NRC inspector observed the inspection of 19 pieces of hollows from ingot Number 224190Q using Quality Assurance Procedure QA-GA-5, Revision 14. This procedure requires that hollows be inspected at ottribute limits specified on form QC 053. QC 053 r m ires that the ID of hollows be inspected with a go-no go gauge which measures 1.625 and 1.655 inches. The SSM inspector was using a go-no go gauge which measures 1.615 and 1.665 inches.
The SSM inspector stopped using the wrong gauge and began to use the specified gauge when questioned by the NRC inspector. .
Nonconformance 87-01-01 was identified in this area.
- 4. Alkaline Cleaning The review of process specification 2121, " Alkaline Cleaning,"
Revision 10, dated June 3, 1985, established that the date that Tank #3 was filled with fresh cleaning solution shall be written on

The NRC inspector observed that the west end of Tank f 3 was devoid of tape or any other forra of the required information. The SSM operator and supervisor placed a tape with the required infomation on the tank when questioned by the NRC inspector.
Nonconformance 87-01-02 was identified in this area.
- 5. Fuel Claddi_ng Fabrication and Inspection The NRC inspector observed 11 steps in the fabrication and inspection of zirconium alloy tubing for fuel cladding and compared the proceoural requirements to the actions being performed by the operators. The following procedures and manufacturing steps were observed:
~
(a) Two reduction steps were performed according to Z181, " Breakdown Rocking," Revision 6, dated September 15, 1986 (L) Deep etching of hollows was performed according to Z140,
" Etching of Zirconium Hollows," Revision 17, dated February 12, 1987.
(c) Etching of tubes was performed according to 2411. "Preanneal Etching of Tubes," Revision 17, dated February 11, 1987.
(d) Three vacuum annealing steps were perfa- led according to Z230,
" Intermediate Hollows - Annealing," Rev s. . 16, dated November 17, 1986.
(e) End chamfering of hollows was performed according to 2160, "Large Hollows - End Chamfering," Revision 7, dated October 11, 1982.
(f) Visual inspection of tubes in lot ABJ 22 was performed decording to NDT-V-50, "First Visual," Revision 7, dated March 8, 1984. -
(g) Ultrasonic test (UT) equipment was prepared for operation to detect flaws in tubing according to NDT-UT-10, " Setup of UT Flaw Inspection Systems for Inspection of Thin Wall Metal Tubing," Revision 7, dated November 23, 1983.
- ORGANIZATION: SANDVIK SPECIAL METALS CORPORATION KENNEWICK, WASHINGTON REPORT INSPECTION Nn - QQQnn764/P7-01 RESULTS- PAGF 5 of 6 (h) UT equipment was prepared for operation to measure dimensions of tubing according to NDT-3D-31, " Setup of the SSM Tubing Dimensional (3D) Test Stations," Revision 7, dated January 29, 1987.
The operators are qualified to work at a number of stations and the NRC inspector observed several different operators at each work station. The operators followed the procedures which were current and at the work stations in compliance with the SSM QAM. No items of nonconformance or unresolved items were identified.
- 6. Internal Audits Internal audit reports for 1985 and 1986 were reviewed to determine conformance with Section 18 of the SSM QAM, Revision 8. Internal
~ audits are performed in accordance with QA-GA-22, " Internal Audit Procedure," Revision 7, dated November 3,1986, which implements all sections of the SSM QAM, Revision 8. Audit reports contain a review by the Quality Control Engineer of tube fabrication compared to an audit checklist generated by a word processor which outlines the requirements in the QAM, procedures, process specifications, and instructiuns for each of 16 production and inspection areas in the plent. Each production and inspection area is audited every six months at the rate of two areas per month.
The NRC inspector determined that the 1985 and 1986 internal audit reports are in compliance with the SSM QAM, Revision 8 and i QA-GA-22, Revision 7. Corrective action (CA) and follow-up l audits to verify CA were performed as required by the QAM and
