-"Attended exit interview Exit Interview The inspection scope and findings were summarized on July 3 and July 18, 1980 with those persons indicated in Paragraph 1 above.
Licensee Action on Previous Inspection Findings Not inspected.
Unresolved Items Unresolved items were not identified during this inspection.
Concrete Work Activities Portions of the following concrete pours were observed:
1CBIW266006 - North Air Duct Shaft Wall on Containment //1,,
1CBXW356001 - Exterior Containment Partial Ring Lift of -Containment jjl WADSM036 - Seal Mat at West Dam Spillway The forms were properly placed, secured, leak tight, and clean.
The rein-forcing steel was secured, clean, and had the proper spacing.
The construc-tion joints were as specified.
The proper design mix was delivered.
Transportation of concrete was according to procedure Testing was done at the placement location, including temperature, air, slump, and cylinders.
The placement crew was adequate for the site pours.
Spare equipment was handy if needed.
Vibrator operators used proper techniques.
Free fall and horizontal movement of concrete was kept to a minimum and in accordance with specification requirements.
There were enough gC inspectors during placement to control the pours.
Water curing was used and was being properly performed.
For the seal mat spillway pour, the rock foundation was cleaned, free of water, loose rock was high pressure water jetted out of the form, and grout was broomed on before the concrete pour.
6.
Batch Plant The batch plant was inspected during each of the previously mentioned pours.
It is a fully automated card controlled system.
The operator was manually reading scales by the control panel to verify the amounts of material being batched.
The admixture sight glasses are in full view.
Temperature control of the mixes is done by adding ice to the mixing water or direct injection of ice to the batch.
Fine aggregate moisture compen-sation is done automatically while coarse is done manually.
Cement is adequately protected in a bin.
Aggregates are well separated and kept cool and moist by fog sprays.
7.
Earthwork Activities Two rock fill-impermeable core dams are being built.
The cross section includes coarse and fine filter material with rock riprap slope protection.
The embankments are approximately half-completed.
Each different type of material is being properly placed and compacted.
Test fills have been performed to determine lift thickness and number of passes of compaction equipment.
Testing is being done at. the required frequency throughout each lift.
8.
Earthwork Design The emergency water intake channel is partially in fill. In view of the silty nature of the material, the inspector questioned the licensee about the use of seeding for slope protection instead of riprap, which would prevent erosion of the fine silty material.
The licensee indicated that the designer left the slope protection up to the licensee.
The inspector questioned whether the portion below the water surface in the channel (unseeded) will be able to remain stable in view of the very silty nature of the fill. This item will be identified as inspector followup items 50-400/80-19-01, 50-401/ 80-17-01, 50-402/80-17-01 and 50-403/80-17-'Ol, Use of'seeding for slope protection instead of riprap.
'arthwork Procedures The following documents were reviewed for consistency with PSAR commitments, NRC guidelines, and industry practice:
Technical Procedure 01, Revision 9,
"Test Fill Program -
Random Fill, Random Rockfill, and Rockfill",
Technical Procedure 02, Revision 14, ~'Soil Control Program - Fill and Backfill for Plant Grade, Plant Building, and Reservoir Concrete Structures" Technical Procedure 08, Revision ll, "Soil Control Program Class
Dams, Fill and Backfill" Specification CAR-SH CH-8, Revision 9, "Excavation, Backfill, Filling and Grading" Specification CAR-SH-CH-4, Revision 10,
"Embandments, Dams, Dikes, and Channels" PSAR Section 2.6 was found to be consistent with site procedures and specifi-cations.
The documents reflect good industry practice as well as NRC guidelines.
10.
Environmental Monitoring During the inspection exit interviewon July 3, the inspector informed the licensee that employees complained to the NRC about the road dust problem on site because the watering trucks are not being used extensively for road dust abatement.
They are also being used for other things such as concrete curing.
The licensee informed the inspector that this matter would be reviewed.
During-the subsequent inspection, the week of July 14th, the inspector along with Mr.
A. Cunningham (Region II Environmental Inspector)
observed that the road dust was again unbearable, to the point where there was zero visibility on the road leading to the main dam.
(see Mr.
Cunningham's Reports No.
50-400/80-18;
'50-402/80-15; 50-403/80-15 for details).
The licensee, during Mr. Cunningham's exit on July 16, again informed the NRC that something would be done about the dust abatement progra ~
