Exit Interview The inspection scope and findings were summarized on July 26, 1979, with those persons indicated in Paragraph 1 above. The licensee acknowledged the noncompliances discussed in paragraph 5.
3.
Licensee Action on Previous Inspection Findings a.
(Closed) Infraction (424/425/79-01-01): Calibration of fine aggregate test sieves. The inspector examined Calibration Instruction C-Ci-35, " Calibration of 8 Inch Sieves", and Calibration Instruction C-CI-36, "Calibratior. f Gilson Screens".
The inspector reviewed certifications furnished by the National Bureau of Standards for the set of master sieves which will be used in sieve calibration.
The ir.opector reviewed the results of the calibration of 8 inch sieves which were performed on July 24, 1979. This item is closed.
b.
(0 pen) Infraction (424/425/79-08-01): Failure to document backfill test data. The licensee has developed a procedure and method for documenting moisture test data. However the field test method for determination of the backfill moisture 1321 036
. ' . g-2-content is still being evaluated by the licensee and Bechtel.
This item remains open pending resolution of the backfill moisture content field test method.
c.
(0 pen) Infraction (424/425/79-11-01): Backfill tioisture control. The licensee and Bechtel are evaluating the Field control method to be used in determination of the backfill moisture content. This item remains open pending resolution of the backfill moisture content field test method.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Independent Inspection Effort The inspector examined the following areas: a.
Construction status b.
Level A. B, and D storage area c.
Concrete and soils laboratory and laboratory equipment calibra-tion program d.
Unconfined compression testing of concrete cylinders e.
Partial placements of pour number A11C004A, a foundation slab in the Unit 2 control br. ~ ding electric tunnel, and pour number AOSD003D, a foundacion slab in the Unit 1 auxiliary building f.
Curing of pour number A11C004A Review of the laboratory equipment calibration program disclosed the following noncompliance.
Calibration Instruction Number C-CI-09, " Calibration of Balance Scales at Soil / Concrete Lab" requires daily calibration of the balance scales in the soils / concrete laboratory by use of a set of test weights traceable to the National Bureau of Standards (NBS). Discussions with responsible engineers disclosed that the laboratory scales had not been calibrated.
In addition, test weights traceable to the NBS were not available onsite for scale calibration. This v2: 'ientified to the licensee as Infraction 424/78-13-01 and 425/79-13-01, " Failure to Calibrate Soils / Concrete Laboratory Scales".
Observation of work activities during placement of pour number A08D003D on July 25, 1979, disclosed the following noncompliance.
Construction procedure CD-T-02, " Concrete Quality Control", paragrapt V.E.2.b.(6) states " Vibrators shall not be used for flowing concrete.
1321 037
. - . -3- , Spacing of vibrators shall be approximate 18 inches (9 . . . inch radius from point of insertion)." Contrary to the above, the inera-observed on several occasions during placement that ere used almost exclusively for moving concrete which vit .ers had accrmn sted at the end of the pump line. The spacing of vibrators ranged from one te five feet during placement. This was identified +o the licensee as -fraction.424/79-13-02, " Improper Concrete Consolidatior. No deviations were identified.
6.
Foundations - Review of Quality Records, Units 1 and 2 The irspector did a followup inspection on quality records concerning excavation for Category I structurer.
The following records were examined: a.
Foundation Excavation Inspection Report b.
Nonconformance Report NCR-CD-263 " Report of Coring and Laboratory Testing - Marl Samples - c.
Power Block Area", by Law Engineering Acceptance criteria examined by the inspector appear in Section 2C of the PSAR, Bechtel specifications X2AB01 and X2AP01, and GPC Construction Procedure CD-T-01.
No deviations or items of noncompliance were identified.
7.
Containment (Structural Concrete I) - Review of Quality Records, Units 1 and 2 The inspector examined the following quality records for structural concrete: QA Audit CD03-79/18, " Audit of Receipt of Bulk Concrete Materials" a.
b.
Results of L. A. Abrasion test performed on coarse aggregate, dated May 18, 1979 c.
Resulta of monthly specific gravity and absorption test performed on coarse aggregate from April, 1979 to date d.
Receiving inspection reports for cement and flyash.
Acceptance criteria examined by the inspector appear in Section 3.8 of the PSAR, Rechtel Specification X2AP01, and GPC Construction Procedure CD-T-02.
I321 038
. ' . . -4- , During review of the above records in the site QA/QC records storage vault, the inspector identified the following problem. Records in the vault are filed using several different systems. The records for any particular item, e.g., concrete aggregate, are filed in several different areas. None cf the files are cross-referenced.
The index of the filing system is incomplete. Records storage personnel had a great deal of difficulty locating records which the inspector requested. Many of the records had been misfiled. The inspector discussed the problem of the retrievability of QC records in the vault with licensee site management. The inspector was informed that the licensee is in the process of selecting a contrac-tor who will provide a proprietary records management and filing system for the project. This area will be inspected by NRC in a subsequent inspection. This was identified to the licensee as Inspector Followup Item 424/79-13-03 and 425/79-13-02, "Retrievability of QC Records".
No deviations or items of noncompliance were identified.
8.
Containment (Prestressing) - Review of Quality Assurance Implementing Procedures, Units 1 and 2 The following procedures and specifications were examined to deter-mine if materials, work activities, quality control and quality assurance functions were provided for as stipulated in NRC require-ments, and FSAR Sections 3.8 and 17.
Bechtel Specification X2AF04, " Containment Post-tension System" a.
b.
Bechtel Drawing Numbers IX2001A006, and IX2001K001 through IX2001K008 c.
VSL QA Manual, " Quality Assurance Program for the VSL Post-Tensionin System Installed in Nuclear Containment Structures" No deviations or items of noncompliance were identified.
