Unresolved Items Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve noncompliance or deviations.
New unresolved items identified during this inspection are discussed in paragraphs 5 and 10.
-
5.
Independent Inspection Effort During routine surveillance site tours the inspector inspected construction activities on peripheral structures such as the intake pumping station, trans-former yards and the component cooling water treatment building. Earth fill and compaction about these structures and the base mat adjacent to the power blocks structure of Plant A were inspected.
Fittings and tack welding of sections of the fifth ring of the A-1 steel containment wall were inspected on July 10 and 11,1980.
Eight stainless steel tanks and three carbon steel tanks (10,000 to 20,000 gallons capacity) were fabricated on site by the vendor, and stored in the field at the fabrication site pending relocation to their installation site;. These tanks have not been accepted by TVA from the vendor. The j
manways and other openings had been left unsealed. When this condition was
!
identified to the licensee, the openings were promptly sealed. The licensee is investigating to determine the storage requirements for these tanks.
This is identified as unresolved item 518, 519, 520, 521/80-15-04.
The inspector inspected ultrasonic examination activities, by a special GE team, on exterior areas of the Unit B-1 reactor pressure vessel stand near the unloading dock.
The vendor had not examined these areas with the automatic ultrasonic examination equipment in the shop because of blocking obstructions. The inspector observed use of the UT sensors in the inspected areas, the monitoring of the wave displayr, and the recording of results.
No determinations of acceptability were made during this inspection by GE personnel. This is identified as inspector followup item 519/80-15-02.
No items of noncompliance or deviations were identified during these obser-vatiocP of construction and testing activities.
6.
Quality Assurance Program Review During this report period the inspector held discussions with two TVA audit,
teams:
-
A welding audit team which was auditing TVA's welding and welding QC programs at all active constru : tion sites following repeated citations at these sites.

(Open) 518/80-15-02 Heaters Omitted from Motor Operator (NCR HNP-097)
i During storage maintenance testing it was found that ne heating element had
'
been installed in the motor control of one RCIC turbine steam inlet valve.
The deficient motor is to be replaced by November 30, 1980.
I (open) 518, 519, 520, 521/80-15-03 Deficiency in Drawing Control (HNP QA Audit HT-G-80-12, Deficiency No.1).
i Approximately twenty percent of the drawings reviewed at various locations throughout the HNP project had been superceded by later revisions to the drawings. Corrective actions to assure compliance with QA program require-ments were being studied by licensee management at the end of this report period.

Status of OIE Bulletins (Open) 80-08 Examination of Containment Liner Penetration Welds i
The licensee's letter of July 7,1980, detailed the results of TVA's investi-
.
gation on these penetration welds. This response is being evaluated.
The licensee received and reviewed for action the following bulletins, none of which is applicable to Hartsville:
(Closed) 79-28 Possible Malfunction of NAMCO Model EA 180 Limit Switchas at Elevated Temperatures - Not applicable. The licensee does not pian to use these switches.

9.
Status of IE Circulars The inspector determined that the licensee has received and assigned for review the following circulars, which are closed for record.
(Closed) 80-16 Operational Deficiencies ~in Rosemont Model 510 DU Trip Units and Model 1152 Pressure Transmitters (Closed) 80-17 Fuel Pin Damage Due to Water Jet from Baffle Plate Corner 10.
Lakes, Dams and Canals - Spray Ponds for Plants A&B During this report period, construction and inspection operations continued in earth fill and compaction and in concrete placements in the essential service water (ESW) pump stations.
The inspector made follow on inspections of earth placement, compaction and testing, and of the placement of the base layers of 3" rocks for the rock dixe.
Additional inspections were made of preparations for placement and placement of concrete in the pumping stations and of curing operations following placement. On the evening of July 29, 1980, the inspector wit-nessed placement of 60 cubic yards of concrete in pour A2KESWP5-57, for a i
wall of A2ESW pump station.
The inspector then observed operation of the north batch plant in mixing concrete for the A-2 turbine building. Leakage of water from feed facil-ities, and sloshing of water from the mixer during charging, resulted in water entering the transport truck prior to and following discharge of mix into the truck. In addition the inspectors noted cement and/or fly ash dust being blown from the charging facilities and mixer. These conditions were reported to the shift supervisor and the QC inspector, who stated that these were intermittent but recurring problems as a result of equipment maladjustment and clogging of the feedwater sluice. Corrective actions were taken then and the following morning.
On this following day the inspector again observed mixing operations.
Water spillage had been cor-rected and loss of cement and fly ash had been reduced to an acceptable level.
Residual mismatch of the mating flanges of the mixer bowl' and charging duct, which rotates to alternate mixers, permitted loss of a minor amount of small aggregate and cement. The civil QC supervisor and the batch plant supervisor stated that the equipment required trequent adjustments to assure acceptable matchup of the mating flanges.
(These deficiencies were not cited as an item of noncompliance because at the time concrete was '
being mixed for nonsafety related structures. The inspector will follow?
TVA's program to insure that these type deficiencies are promptly identified and corrected while mixing concrete for safety related structures. (Unresolved Item 50-518, 519, 520, 521/80-15-05.))
