Exit Interview 3.
The inspection scope and findings were summarized on February 22, 1980 with those persons indicated in Paragraph 1 above.
The licensee acknowledged the noncompliance discussed in paragraph 7.b.
,I Licensee Action on Previous Inspection Pindings a.
(Open)
Unresolved Item (400/79-07-03, 401/79-07-03, 402/79-06-03, and 403/79-06-03),
Category I Piping Fill Support.
The licensee has completed evaluation of the subgrade for the service water lines between the intake structure and the No.
1 Tank Building from station coordinates N525 and N890 and subgrade for electrical duct bank be-tween the same structures from station coordinates N406 and N682.
The inspector examined field inspection reports, field density and one point proctor test results, and discrepancy report C-274 which docu-ments the licensee's evaluation of the service water line's and duct bank's subgrade.
The testing and evaluation was performed in accordance with applicable procedures and licensee commitments to NRC.
The group 5A-A service water lines between station coordinates W1600 and W2000 are founded on rock.
Therefore field density testing was not required to determine subgrade conditions in this are Placement of fillconcrete adjacent to No.
1 Tank Building as backfill under the service water lines has been completed.
The inspector exam-ined the pre-pl'acement and placement checklists for this pour (placement number 1HCFC249001),
results of tests performed on the plastic concrete for slump, temperature and air content, and results of 7-day and 28-day compressive strength tests performed on cylinders from the pour.
The concrete placement activities are in accordance with design requirement and applicable procedures.
The inspector also examined a draft of Revision 13 to Technical Procedure TP-02, "Soil Control Program-Fill and Backfill for Plant Grade, Plant Buildings and Reservoir Concrete Structures",
which incorporates require-ments of additional in-place testing which is to be performed under pipes and duct banks where fillis greater than 10 feet.
This item remains open pending further evaluation by NRC and completion of additional inplace testing by the licensee.
b.
(Open)
Noncompliance (400/80-01-01, 401/80-01-01, 402/80-01-01 and 403/80-01-01),
Improper Curing of Concrete Cylinders in the Concrete Laboratory.
The inspector discussed planned corrective actions with licensee engineers and observed installation of a new fog spray system in the curing room.
This item remains open pending completion of the licensee's corrective action.
c ~
(Closed)
Unresolved Item (400/80-04-01),
Recording of Concrete Curing Temperatures on the Concrete Curing Log.
The inspector examined a

"Concrete", authorized by Field Change Request number FCR/C-1135.
The inspector examined the Concrete Curing Temperature Log from,pour number f
1CBlW260001.
The concrete temperatures maintained during curing of this pour comply with the requirement of ACI-306 and specification CAR-SH-CH-6.
This item is closed.

Iakes, Dams and Canals-Observation of Work and Work Activities-Units 1, 2, 3 and 4 The inspector witnessed partial placement'f pour number WAD ST 040, a mass concrete pour in the OG section of the west auxiliary dam spillway.
Forms were tight, clean, and level.
Placement activities pertaining to delivery time, free fall, flow distance, layer thickness and consolidation conformed to specification requirements.
Concrete placement activities were continu-ously monitored by inspectors.
Examination of batch tickets indicated that the specified design mix was being delivered.
Samples of plastic concrete were tested in accordance with specification requirements.
The test results indicated that the plastic concrete being placed met the mass concrete specification requirements for slump, air content and temperature.
Acceptance criteria examined by the inspector appear in PSAR Section 5, EBASCO Specification CAR-SH-CH-6, CPSL Procedures CQC-13, TP-15, and QCI 13.3, and drawing numbers CAR 2167-G-6280, 6281, 6282, 6284, 6285 and 6286.

No deviations or items of noncompliance were identifie b.
Emergency Service Water Canal Fill Records The licensee, in a letter dated August 2, 1979, to NRC Region II, requested concurrence in the acceptability of the emergency service water (ESW)
canal fill material which was placed without moisture control and release for continued construction of the canal.
On August 22, 1979, in a telephone conversation with NRC Region II and NRR representatives, the licensee agreed to revise specification CAR-SH-CH-4 to specify moisture control for some types of canal fill, and perform testing on the inplace fills materials or remove them.
The licensee submitted the revised specification CAR-SH-CH-4 to NRC for review in a letter dated September 6,
1979.
On September 7,
1979, in a telephone conversation with NRC Region II and NRR representative, the licensee informed NRC that the fillmaterials in question wquld be removed and replaced with new fillin accordance with the requirements of the latest revision of Specification CAR-SH-CH-4.
The inspector examined the quality records documenting removal of the questional fillmaterials and placement of new fillmaterials in the ESW canal.
Acceptance criteria examined by the inspector appear in PSAR Appendix 2E, EBASCO Specification CAR-SH-CH-4, and CPSL procedures TP-08 and CQA-9.
The following records were reviewed:
(1)
Field inspection reports for period August 28, 1979 through December 21, 1979 (2)
Results of field density tests and one-point proctor tests performed between August 30, 1979 and December 15, 1979 (3)
Discrepancy report numbers C466 and C467 and permanent waiver number PW/C-1104 (4)
Training and qualy<ications records of 5 soils construction J
inspectors Review of the above records disclosed the following noncompliance.
Paragraphs 4.1.2.3 of CPGL Technical Procedure TP-08 requires a one-point proctor test to be completed for each density test to verify correct completion curve selection for moisture and percent compaction.
Contrary;"o this requirement, one point proctor tests were not performed for field density test numbers ESW-33, ESW-65, ESW-66, ESW-96, ESW-98, ESW-103, ESW-104, ESW-110, ESW-110R, ESW-124, ESW-125.
This was iden-tified to the licensee as Infraction Item 400/80-06-01, 401/80-06-01, 402/80-06-01, and 403/80-06-01,
"Failure to perform one-point proctor test".
No deviations were identifie.
Containment (Structural Concrete II) - Observation of Work and Work Activi-ties - Unit
The inspector observed construction repair activities underway to voids in the concrete under the six main loop pipe penetration sleeves in the primary shield wall.
The inspector reviewed drawings showing details of the repairs, discussed repair techniques with licensee and contractor engineers, and dis-cussed with licensee engineers steps to be taken to avoid similar problems on future placements in similiarly highly congested areas.
The completion of the'epairs to the primary shield wall and changes to concrete placement techniques for placements in highly congested areas will be reviewed by NRC in a subsequent inspection.
This was identified to the licensee as Inspector Follow-up item 400/80-06-02,
"Repairs to primary shield wall and concrete placement techniques in highly congested areas".
The inspector also observed partial placement and inspection of pour number 1CBXW276001 in the Unit 1 containment building wall.
