C.
(Open) Deviation (400/401/79-07-01 and 402/403/79-06-01):
Failure to Control Moisture Content of Powerblock fillDuring Placement.
Specifi-cation CAR-SH-CH-8 and procedure TP-02 have been revised to control moisture backfill around Category-g buildings at plus or minus
percent of optimum, instead of at optimum as specified in the PSAR.
Also a permeability test will be made for each 2000 cubic yards of backfill placed.
Results of tests on previously placed material, and data supporting the change from placement at the optimum moisture content specified in the PSAR are being reviewed by NRR.
This item remains open pending NRR approval of changes submitted by the licensee.
(Open) Noncompliance (400/401/79-07-02 and 402/403/79-06-02):
Failure to Place Embankment Core Fills At Specified Moisture Content.
The Licensee has evaluated material placed out of specification and sent the evaluation to EBASCO for approval.
Subsequent to EBASCO'S approval the evaluation will be sent to NRR for approval.
Impervious fill placed in the separating dike has been removed.
This item remains open pending NRR and RII, IE approval of the licensee's evaluation.
(Open)
Unresolved Item (400/401/79-07-03 and 402/403/79-06-03):
Category I Piping Fill Support.
The licensee's evaluation of this item has been sent to EBASCO for approval.
Subsequent to EBASCO's approval the evaluation will be reviewed by NRR and RII, IE.
This item remains ope I

Unresolved Items Unresolved items were not identified during this inspection.
5.
Independent Inspection The inspector examined the concrete reinforcing steel laydown area and grouting records on the West Auxiliary Dam.
Consolidation grouting has been completed between stations
+ 00 to 3 + 95 and 20 + 00 to 39 + 00.
Curtain grouting has been completed between station 0 + 00 to 3 + 30 and
+ 50 to 39 + 00.
No deviations or items of noncompliance were identified.
6.'akes Dams and Canals - Observations of Work and Work Activities, Units 1, 2, 3 and 4 The inspector performed a followon inspection of subsurface preparation at the Main Dam and Vest Auxiliary Dam.
Acceptance criteria examined by the inspector were:
a.
PSAR, Section 2 and Appendix 2E b.
SER, Section 2.5 r
c.
CAR-SH-CH-4, Embankments and Dams, Dikes and Channels d.
Drawings CAR-2167-G-6241 through CAR-2167-G-6245,
"Reservoir Main Dam, Profile and Typical Sections" e.
Drawings CAR-2167-6270, 6272 and 6273, "Reservoir, West Auxiliary Dam, General Plan, Profile and Typical Sectipns" Observations included examination of excavations and geologic mapping in the West Auxiliary Dam and Main Dam core trenches.
Observations are as follows:
a.
West Auxiliary Dam Examination of excavations and mapping were between stations-1+60 to 4+95 and 14+05 to 'l8+90.
The area has been excavated into nearly horizontal, northeast, trending Triassic sandstones, shales and silt-stones.
Examination of the core trench between the above stations disclosed a fault crossing the core trench at station 4+27.
The fault strikes about north, 80 degrees east and dips about 65 degrees southeast.
The fault is a normal fault with a 15 foot wide drag zone on the south side showing that the south block has gone down with respect to the north block.
Geologic mapping in the core trench and the geologic report on the "Plant Fault" indicate that the fault crossing the West Auxiliary Darn core trench is a westward extension of the "Plant Fault"
encountered in excavations for the Waste Process building in July 1979.
NRC concluded in supplement number 3 to the SER that evidence indicated movement along the "Plant Fault" occured prior to 136 million year ago and therefore it was not a capable fault.
Observations showed no other anomalies between the above stations and that site preparation and geologic mapping were being done in accordance with NRC requirements.
b.
Main Dam The inspector examined results of site preparation and geologic mapping in the core trench between stations 9+00 to 12+50.
The area consists of Pre-Triassic tightly infolded mica shist and gneissic granite.
Examination of mapping disclosed that an anomaly reported in NRC IE report number 50-400/79-07 as a fault has been reclassified by the licensee and now the anomaly is not considered a fault.
In the above report the anomaly, located 17 feet upstream of dam centerline station ll+51 appeared to show 5 to 14 inches of left lateral offset of 5 to 14 inch quartz veins along a shistose layer.
As a result of cleaning in the core trench the shistose layer is now visable as a fold tightly infolded with the granite.
Joints extending into the limbs of the fold show no offset and a quartz vein along an eastern extension of the fold trace shows no offset.
The quartz veins originally interpreted as exhibiting a faulted offset appear to be two separate veins which are truncated by 'the folded shist layer.
A final draft report on this fault and a fault occuring opposite conduit station 5+48 (discussed in IE Report 50-400/79-07)
was examined by the inspector.
The final report will be submitted to NRR for review.
Geologic mapping and site preparation were in accordance with NRC requirements.
No deviations or items of noncompliance were identifie w (
