INTRODUCTION This evaluation was performed as a result of a Sequoyah Nuclear Plant (SQN) specific employee concern, number XX-85-027-X02.
II.
SUMMARY
OF PERCEIVED PROBLEM The perceived problem is as stated in concern number XX-85-027-X02,
" Material inspectors were not allowed to validate heat numbers of structural steel received on site as required by procedure [;] heat lR1 No. 7438383 is an example."
III. EVALUATION METHODOLOGY A.
Reviewed expurgated files to obtain additional information.
B.
Reviewed Employee Concerns Tast Group (ECTG) working files to obtain additional information.
C.
Reviewed Nuclear Safety Review Staff (NSRS) unexpurgated files to obtain additional information.
D.
Reviewed Site Procedures to determine the requirements for validation of heat numbers.
E.
Conducted interviews to determine if any instances of material inspectors not being allowed to validate heat numbers for material received on site were known.
j IV.
SUMMARY
OF FINDINGS l
l A.
A review of the expurgated files revealed the number of an NSRS i
report, which was, "(NSRS) Report Number XX-85-027-X02."
8.
A review of the ECTG working file revealed an Employee Response Team (ERT) Investigation Report number XX-85-027-X02 and associated correspondence. This correspondence indicates that NSRS Report Number XX-85-027-X02, referenced in Section IV.A, of this report (MC-40705-SQN), is in fact the ERT Investigation Report Number XX-85-027-X02.
l ERT Investigation Report Number XX-85-027-X02 did not address the lR1 perceived problem as stated above; however, it contained the l
following conclusion:

TVA EMPLOYEE CONCERNS REPORT NUMBER: MC-40705-SQN SPECIAL PROGRAM REVISION NUMBER: 1 PAGE 3 0F 6 "This concern is not substantiated. This conclusion is based on the following:
(1) Interviews of the other material inspectors provided no evidence to support an impedance of inspectors to validate heat numbers as directed in the approved procedures.
(2) Material heat numbers randomly extracted from the H.N.S.*
satisfactorily proved themselves to be adequate in that proper certified material test reports were readily available for all numbers picked.
The discrepancy noted in the observation section of this report requires further evaluation by TVA."
This conclusion "This concern is not substantiated", is concurred with. Basis number (1) is agreed with, see Section IV.E. of this ECTG report (MC-40705-SQN). Basis number (2) is not agreed with due to the results of the heat code evaluation performed at SQN in ECTG Report MC-40703. A Certified Material Test Report (CMTR) for i
each of the eleven heat numbers, including the example heat number i
7438383 given by the Concerned Individual (CI), referenced in the ERT l report was requested from the Quality Control Record Vault (QCRV).
IR1 Only four of the eleven requested CMTRs were obtained from the QCRV, I
one of these four was the example heat number 7438383 given by the CI. I However, one heat number (3457) referenced in the ERT report is not I
listed in the Heat Number Sort Printout (HNSP).
I NOTE:
ECTG report MC-40703 for SQN programmatically addresses material traceability to its CMTR.
The discrepancy noted in the observation section of the ERT Report is, there is nothing adequately describing the use, methods of maintenance or controlled distribution of the HNSP as required by 10 CFR 50. Appendix B, Criterion V.
This discrepancy became an l
NSRS recommendation (Q-85-027-XO3-01) to SQN. SQN's response, l
"... generation of a new procedure to control a document no l
longer in use at SQN is not justified.", is contained in the ECTG l
working files. The H.N.S.* is no longer in use because it was used IR1 during the construction phase which has ended.
SQN's, " Corrective l
i Action Response Evaluation", was " accepted" by NSRS and ERT report XX-85-027-XC2 closed. The NSRS acceptance transmittal is maintained I
l in the ECTG working files.

SPECIAL PROGRAM REVISION NUMBER: 1 PAGE 4 0F 6 SQN's response to and NSRS's closure of this discrepancy is concurred with. The results of a lack of a procedure governing the HNSP are addressed in ECTG report MC-40703 for SQN.
NOTE: Although no specific timeframe can be established for this concern, it was determined to be construction related due to ERT report references to Construction Procedures and the concurrence of the Concerned Individual (CI) with the results of the subject investigation, as stated in the report, "... The CI was contacted to discuss results of the subject investigation and does not have any further questions in the area."
A review of the NSRS unexpurgated files revealed no additional C.
information.
Site Procedures governing the validation of heat numbers, consisted D.
of the following:
SNP Inspection Instruction No. 30. " Receipt Inspection" (II-30), Revision 0, dated 05/04/77 through Revision 7, dated 09/20/82.
SNP Construction Procedure No. P-34, " Heat Number Validation" (P-34), Revision 0, dated 06/13/77 and Revision 1, dated 12/13/78.
SNP Inspection Instruction No. II-39, " Heat Code Transfer and ASTM
- Designator Transfer" (II-39), Revision 0, dated 05/04/77 through Revision 2, dated 12/11/78.
These procedures required the validation of heat numbers / codes of material, upon receipt at SQN, by the Material Inspection Group.
Interviews conducted with Materials Inspection Personnel, active j
E.
during the construction phase of SQN revealed no known instances of Material Inspectors being prevented from validating heat numbers / codes of material received on site, as required by the procedures.

Conclusions Based upon the findings of this evaluation, there was no indication of l
material inspectors not being allowed to validate heat numbers on IR1 received material during the construction phase.
