Exit Interviews The weekly inspection scope and findings were summarized with the project manager on June 4, June 13, June 20 and on June 27, 1980.

Licensee Action on Previous Inspection Findings a.
(Closed) Deficiency 518, 519, 520, 521/79-29-01, Batch plant Water Control.
The licensee's response to this citation was dated February 19, 1980.
It stated that the frequency of inprocess free moisture tests of fine aggregates had been increased to once before starting batching opera-tions and then every two hours thereafter. The results are used to set moisture compensation on the mixing plant, to reduce variations in-recorded water data.
In addition C. F. Braun Specification 300-01 STRIDE, Concrete, Revision 8 dated May 15, 1980, altered Sections 4.7.2, 4.7.3 and 4.7.4 to reflect the above changes. The licensee's response and corrective actions are acceptable.

(Closed) Insprctor Followup Item 50-518, 519, 520, 521/80-05-01 Unac-ceptable Delay in Audit Corrective Actions.
The auditing unit now finds acceptable level of response on corrective actions by the site construction forces.
,
c.
(Closed) Deficiency 520/80-08-04 Failure to follow Procedures for Storage of RPV.
Temperatures and humidity measurements are being made daily as required.
RIS & PM procedure M-650 has been revised to delete the prohibition of storage near unpaved road.
The licensee's response dated June 24, 1980, is acceptable.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Independent Inspection Effort
Follow on attention was paid to the licensee's processing of QCIR's and NCR's (Quality Control Investigation Reports and Nonconforming Condition
" ports).
The site is publishing a weekly QCIR report, broken down by STRIDE, BOP, and Plant A tabulations. These show the number of QCIR's opened, disposi-tioned, or closed during the previous week by construction discipline. The summary shows the net decreases or increases in the backlog of QCIR's. The NCR status report, published monthly, lists open NCR's. Plant B curtailment has complicated closure of NCRs involving both Plant A and Plant B since corrective actions at Plant B are on indefinite delay. This problem is being studied by the licensee t> try to find a method for clearing older JCRs.
No nonconformance or deviation was identified during the inspector's review.
6.
Licensee identified 50.55(e) Items a.
Status of Previously Identified Items (1)
(Open) 518, 519, 520, 521/79-27-05 Rebar Bending Not in Accordance with Site Procedures (NCR YC-023). The licensee's final report dated February 1, 1980 specified that Construction must obtain design approval before bending of partially embedded rebar. For STRIDE structures, C. F.
Braun Specification 300-41 requires SE/C. F.
Braun approval before bending of partially embedded rebar.
Necessary approvals are being obtained by construction personnel before bending partially embedded rebar on BOP struc-tures. By verbal instruction GE/C. F. Braun have delegated back to TVA project engineering authority to approve bending on STRIDE structures except where large numbers of bars are involved. The p
.
.,
-3-site QA Unit auditor believes that such delegation _ of approval authority requires a written instruction from GE through C. F.
Braun to TVA; so this item remains open.
(2)
(Closed) 518, 519, 520, 521/80-08-02 Incorrect Root Face on Skewed Cadweld Sleeves (NCR HTN CEB 80-04).
GE/C. F.
Braun reviewed the test results and weld geometry calculations for specimens - prepared from the incorrectly started sleeves and concluded that the sleeves can be used as-is.
The licensee's final report was transmitted June 19, 1980 and is acceptable.
b.
Newly Identified Items (1) ' (0 pen) 518, 519, 520, 521/80-13-01 Atlas Machine & Iron Works QA - Steam Tunnel Embeddment Stiffener Plate Weld. (NCR-10; HTN QEB 80-01)
A TVA audit of Atlas' QA program identified sixteen deficiencies of which nine were considered significant. A contract engineer and a QA evaluator have been sent to Atlas to advise and aid in
,
QA program difficulties. A final report is due by September 19, 1980.
(2)
(0 pen) 518, 519, 520, 521/80-13-02 Standby Gas Treatment System Charcoal Adsorber (NCR HTN NEB 80-02)
As a result of investigation prompted by IE Bulletin 80-03, all eight of the SGTS charcoal adsorber beds were found to have sepa-rations between the charcoal retention screens and the frames to which the screens are mounted. A final report is to be filed by August 20, 1980.
(3)
(0 pen) 518, 519, 520, 521/80-13-03 Defective McGraw-Edison Temper-ature Detection Controllers In the Standby Gas Treatment System (SGTS) (NCR HNP-A-100)
The licensee's final report on this matter, dated June 13, 1980, states that all potentially defective controllers for Hartsville will be' returned to the vendor, CTI Nuclear by July 31, 1980.
They are to be replaced with controllers verified to have been sealed or soldered properly.
7.
Status of OI&E Bulletin The licensee received and reviewed for action the following bulletins, none of which applied to Hartsville:
(Closed) 80-12. Decay Heat Removal System Operability (Closed) 80-13 Cracking In Core Spray Spargers (Closed). 80-14 Degradation of BWR Scram Volume Capability (Closed) 80-15 Possible Loss of Emergency Notification System (ENS) With Loss of Offsite Power

Status of IE Circulars The. inspector has determined that the licensee has received and assigned for review the following circulars, which are closed for records:
(Closed) 80-14 Radioactive Contamination of Plant D'emineralized Water System and Resultant Internal Contamination of Personnel.
(Closed) 80-15 Loss of Reactor Coolant Pump Cooling and Natural Circulation Cooldown 9.
Lakes, Dams and Canals - Spray Ponds for Plants A&B During.this report period, substantial progress was made in earth fill operations and in placing concrete in the essential service water (ESW)
pump stations.
The inspector made follow on inspections of earth p acement, compaction and testing, and of-the placement of the base layers of 3" rocks for the rock dike. Additional inspections were made of preparations for placement of
concrete in the pumping stations and of curing operations following place-ment.
The earth and rock work criteria are described in TVA Construction Speci-fication N 6C - 875, Revision 12 dated 3/28/80, " Earth and Rock Foundations and Fills" and by notes on the construction drawings; and SRN-N6C-875-23 dated May 6, 1980 and SRN N6C-875-24 dated May 28, 1980.
Inspection and testing are guided by Civil Quality Control Instruction C-102, Revision 7, dated 8/30/19, " Foundation and Fill, Earthfill Control Testing". Concrete installation is controlled by C. F. Braun Specification 300-01 CONCRETE thru Revision 8, dated May 15, 1980. Inspection and testing is controlled by TVA Civil procedures QCI-C-201 to 218.
No noncompliances or deviations were identified.
10.
Concrete in Plant A Power Block Structures Finishing and curing operations were inspected on the second and third concrete placements in the A-1 vent wall.
Preparations for placement A2R-2Ea in the fifth wall lift in A-2 containment shield buildings were inspected. The inspector verified the correctness of ongoing curing operations. One half of the eighth shield wall lift for the A-1 containment (placement AIR-2H, 196 cubic yards) was placed on June 11, i
1980. The inspector inspected installation of rebar, embedments and frames.
Correctness of curing operations was verified.

Containment (Steel Structures, and Supports) Observation of Work and Work Activities In Unit A-1 the inspector inspected repair operations on the anchor _ bolt chair welds at the base of the containment wall (Reference 50.55(e) Item 518, 520/79-17-20). Preheating was being properly done and QC inspector coverage was present at each work station.
A follow on inspection was made of assembly and repair work on the upper and lower sections of the A-1 biological shield wall. This work is being done in the fabrication shop area. The repairs are to correct defective welding by Industrial Engineering Works and to replace sections of base metal in which cracks were detected (Reference 50.55(e) Item 518/80-05-03).
In Unit A-2 containment the inspector made follow on inspections for place-ment and assembly of the first ring of the steel containment wall, the vent.
wall and reactor pedestal.
These installations are controlled by work packages D-009-M1, D-014-M1, D-256-M1, D-259-M1, D-260-C1, and D-264-M1.
