,
Storage Areas.
The inspector examined the licensee's response dated August 11, 1981, and the implementation of the response. " Designated Eating Area" signs have been posted throughout the warehouse. Contractor personnel
have been shown designated eating areas and have been informed that they must comply with all warehouse regulations.
Inspection of both the ware-house and the NSCS Morage yard revealed satisfactory conditions.

QA Inspection of Structural Concrete Performance (350618)
This inspection was performed to determine that site work is. being performed in accordance with NRC requirements and SAR commitments; that the QA/QC program is functioning in a manner to assure that requirements and commit-
,
i ments are met; and that prompt and effective action is taken to achieve permanent corrective action on significant discrepancies.
For concrete
<
placement No A-09B-005B, The Fuel Handling Building Cask Loading Pit, the following areas were examined to verify the inspection objectives.
a.
Field Drawings, Specifications, and Procedures
Bechtel Drwg No. AX2009A005, R1 Bechtel Drwg No. AX2009A006, R8 Bechtel Drwg No. AX2D94V019, R18
GPC FCR No. C-FCRB-2676 GPC FCR No. C-FCRB-2578 GPC FCR No. C-FCRB-2668 Bechtel DCN No. 4 to Drwg No. AP09B036, R3 Specification X2AP01, R39, Forming, Placing, Finishing anc Curing Concrete
Procedure CD-T-02, R9, Concrete Quality Control
,
!
The inspector reviewed the above listed documents to determine whether l
the most recent revisions of field drawings, construction specifica-tions, and procedures are in agreement with the SAR.
The listed applicable field change requests (FCRs) and design change notice (DCN)
were examined to determine that they had been properly reviewed,
,
approved, and processed. The procedure and specification were examined to determine whether they adequately describe inspection and testing requirements to properly reflect the design intent of the structure.
b.
Field Inspection
<
i
The inspector made a detailed inspection of concrete placement acti-l vities concerning pour No. A-098-005B. The forms were tight and clean I
with rebar properly installed and clean. Preplacement inspection was

l indicated by the signed preinspection form.
Placement activities pertaining to delivery time, free fall, flow distance, layer thickness, and consolidation of concrete were adequata.
In process sampling of concrete for strength testing, temperature, slump, unit weight, and air content met required frequency requirements. An examination of batch plant operations and batch tickets indicated that the proper mix was being delivered to the placement, that materials were being controlled, and that accurate batch plant records were being generated. Inspection of the volumetric dispensers of air entrainment and water reducing agents disclosed that the subject dispensers had out-of-date calibra-tion stickers displayed on these items. Pursuing the matter further, the inspector was shown documentation indicating that these items had been calibrated but QC failed to change the stickers. The concreting activities were continuously monitored by adequate numbers of QC inspectors. The inspector observed the concrete foreman and craftsmen at work and conducted discussions with randomly selected personnel to determine that their knowledge of concreting activities was adequate.
The inspector attended a critique conducted January 13, 1982, con-cerning the subject placement in which supervision, QC, and engineering personnel participated from both GPC and Walsh Construction Company.
The inspector found this approach helpful in that it aired any problems encountered during the placement and discussed corrective actions that could be taken to prevent recurrence during later concrete placements.
c.
Quality Control Quality records examined by the inspector pertaining to this placement included batch tickets, batch plant inspector reports, daily inspection reports, concrete pour cards, test data for air, slump, unit weight, and temperature, and molding of concrete test cylinders.
Discussions were conducted with various QC inspectors associated with the subject placement to determine that their knowledge of batch plant operations, testing, placing, finishing, and curing concrete were adequate and to determine whether their findings received proper attention.

d.
Nonconforming Items Reports (NCR)
The inspector reviewed selected reports of construction discrepancies for various concrete placements to verify that the corrective action accomplished the following:
(1) Corrected the items (2) Determined the cause of the deficiency (2) Considered reportability to NRC (4)
Instituted effective action to prevent recurrence
,.
.
Nonconformance and deviation reports reviewed included the following:
CD - 1592 CD 1404 CD - 1565 CD 1395 CD - 1546 CD 1378 CD - 1533 CD 1349 CD - 1466 CD 1348 CD - 1436 CD 1340 CD - 1416 The QA section periodically conducts reviews of nonconformance reports for all disciplines (such as Audit GD05-81/58) to identify potential trends or areas of concern that may be developing.
e.
Calibration of Equipment The inspector examined the in process concrete testing equipment utilized for this placement and the concrete batch plant scales and equipment for current calibration stickers. Other than the discrepancy discussed in paragraph 5.b which was immediately rectified, all equip-ment examined was found in calibration.
f.
Audits The inspector reviewed the following audits which had been performed on various phases of concreting operations:
CD03 - 31/89 QA Audit of Concrete CD03 - 81/74 Concrete CD03 - 81/45 Concrete CD03 - 81/20 Concrete CD03 - 81/19 Concrete Temporary Blockouts CD03 - 81/02 Concrete Documents CD03 - 80/39 Concrete Placement The above audits were examined to determine if they were meaningful, effective, reflect quality performances, and whether corrective actions taken as a result of audit findings were proper, timely, and complete.
Within this area, no violations or deviations were identified.
6.
Site QA Audit Personnel Training and Qualifications (35060)
The inspector examined the QA Department Annual Training Report - 1981 data package transmitted by memorandum (Correspondence No: QA-1157) dated 1/9/82 and conducted discussions with four relatively new site auditors. Quali-fication records examined and the above discussions ascertained that new auditors had been given the appropriate training / orientation and possessed the necessary experience to perform the QA audit functio _ _

l
As new auditors, they were first employed under the tutelage of a lead
<
auditor performing team inspections.until they obtain an acceptable degree of on-the-job experience.
They now perform audits on their own but are
!
'still subject to the guidance, counseling, and approval of audit plan checklists, audit findings, and audit reports by the QA Site Supervisor,
'
a certified lead auditor.
Within this area, no violations or deviations were identified.

Field Change Notice Controls (92704B)
A Field Change Notice (FCN) is a document orginated and approved by field engineering (Assistant Project Section Supervisor or above) to allow work to proceed with subsequent Bechtel home office design engineering review and concurrence.
'
A letter from Mr. D. E. Dutton to Mr. D. G. Eisenhut, NRR, dated October 15, 1981, subject, Field Change Notice Controls, delineates controls which have been placed on the initiation, handling, and resolution of FCNs. This let-ter commits QA to a 100 percent audit / review of all FCNs issued during the first six months to verify implementation of controlling procedures, the
necessity for FCNs in lieu of Field Change Requests, control of FCNs and the
~
adequacy and timeliness of Bechtel's response. The letter also states that a joint bi-monthly review of all FCNs will be conducted by the managers of QC and Field Operations.
i A review was conducted of Field Procedure Change Notice 10 to procedure DC-A-03, R8, and Desk Top Procedure DT-C-07, R0, which provide controls
,
over the FCN program.
The inspector examined the findings mentioned in
QA Audit GD07-81/99 which reviewed all FCNs written as of December 12, 1981.
The results of the bi-monthly review conducted December 14, 1981, by the managers of QC and Field Operations which are detailed in a memo-randum to the vault file dated December 16,1981 (File No. X7BC23, X7BF10)
.
were reviewed by the inspector.
It appears that the turn-around time (i.e., the time to get Bechtel's
'
written response to the FCNs) has averaged about ten days whereas GPC i
committed to no longer than five days.
GPC feels this additional time interval for Bechtel response can be attributed to the newness of the FCN p ogram and will be corrected. The bi-monthly review concluded that for
'
the FCNs written to date, there has been no evidence of abuse of the system.
Within this area, no violations or devations were identified.
