Licensee Action on Previous Inspection Findings (Closed) Violation (518/520/80-27-03) Failure to adhere to procedure and specification requirements for placing concrete. The licensee's response dated March 16, 1981, has been reviewed by the inspector and found to be acceptable.
The licensee had taken immediate corrective actions on the infractions during the placement and asserts that full compliance was achieved on February 24, 1981. Existing control documents appear adequate.
i (Closed) Unresolved Item (519/81-03-01) Procedure change for Unit B-1 reactor pressure vessel (RPV) storage maintenance.
The licensee has i
completed the substitution of dehumidification equipment inplace of heated l
air for mMsture control of RPV intervals.

Independent Inspection Effort The inspector made surveillance tours during which the status of project
'
work was noted, and construction activities were inspected on r.ucitar safety-related structures, systems and facilities.
The inspection uas concentrated on Plant A power block structures, but included outiying structures such as:
the intake pumping station, NA0H hypochlorite plant footings, A-1 circulating cooling water (CCW) pump house, Plant A make up water treatment plant, and Plant A switchyard r elay station. Most of the tanks, mechanical and chemical equipment, and electrical control equipment in the water treatment plant and electrical relay station was found to have been positioned in place and the electrical and pipe connections were started.
Open Items Control:
Nonconformance reports (NCR's), significant quality control inspection reports (QCIR's) and QA unit audit findings were reviewed for pertinence to the inspection program.
Blasting: The inspector verified that the daily afternoon blasting for excavation of trenches and subsurface tanks for Plant A were controlled to avoid damage to nearby structures.
Document Review: The inspector reviewed the latest revisions to C. F. Braun specifications 400-03, Field Fabrication and Erection of ANSI B31.1 Piping, 400-15, Field Fabrication and Erection or ASME Section III, Piping, and FC 1585, Field Change Procedure.
The inspector discussed with the hanger project engineering unit supervisor, the omission of stipulations in SOP-44, QA Component Support Program, for i
j the structural supports and simple pipe hangers. The surervisor stated that a separate SOP is being prepared, and installation packages assembled as required manpower becomes available.
Present efforts are concentrated on structural supports and simple pipe hangers unde * S0P-44.
l In the areas inspected, no violations or deviations were identified.

10/20/80 (0 pen) (518/520/80-27-02) Inadequate Wedge Bolt Expansion Anchors by Rawlplug (NCR HTM-CDB-8002). The licensee has determined that one-inch Rawlplug anchors are adequate for STRIDE supports already installed; but they are -inadequate for certain STRIDE pipe systems and for TVA designed systems in balance of plant (BOP) structures.
Therefore, one-inch Rawlplug anchors are to be removed from the Hartsville site before additional systems are installed. The removal is scheduled to be completed by April 10, 1981.
(0 pen) (518/519/520/521/81-03-03) Deficient Drawing and Document Control (HTRD-50-518,-519,-520,-521/81-05)
(Reference Infraction 518/519/520/521/80-18-01) The licensee's final report dated March 16, 1981, outlined root causes of the control problems and stated that a revision to C.E.P.- 6.01 Drawing Control had been drafted.

The licensee's final report cn this item, dated March 27, 1981, states that the deficient weld or, the steam tunnel embedment stiffener plate was cleared. Discrepancies in other embedments being fabricated by Atlas on separate contracts were found by TVA during additional inspection and auditing. TVA terminated their contracts with Atlas and is seeking another vendor or vendors to complete these embeaments.

Preventive Maintenance and Storage Conditions for Safety-Related Items The inspector continued surveillance of eaufpment and materials in storage, in field transit storage and " stored in place". The inspector verified that openings in valves, pumps, piping and vessels were covered as required by QCI-M-210, SOP-27 and ANSI N45.2.2.
The inspector made a detailed inspection of storage and preventive main-tenance of the eight large emergency diesel generator units for plants A and B.
The diesel engines are stored in pairs in four locked Kelley prefabri-cated shelters.
They are mounted on oak cribbing on gravel base with provisions for drainage.
Instructions for storage by the manufacturer, Delaval, assumed that assembled units would be stored, covered with tied down tarps and with coils in the motors and stators protected from moisture by electric current heating.
The stored engines do not have elements requiring heat for protection so they are stored at "C" level. The stators and rotors were found to be stored in four locked warehouses (AWC, AWE, BWN and TWP) at required level "B" and with their coils protected by electric heat.
As required by paragraph 6 of TVA's RIS & FM Procedure Mechanical M-539, Rev.1, QCIR's 27713 and 27753 had been approved to formalize storage conditions different from but equivalent to the suppliers' stipulations. The inspector verified that each rotor and stator was covered and its windings
,
were provided with heat; and verified that the required periodic meggering of the windings was being parformed and recorded.
No violations of requirements was identified.
8.
Concrete Forming, installation of rebar, positioning of embedments, placements and post placement curing were inspected as work progressed in the Plant A fuel buildings, auxiliary buildings, control buildings, and essential service water pump houses. Completed concrete and new forcing were inspected in the intake pumping station.
Specific placements inspected included A1A-10F,
-11F, -12F; A2A-12C&D, -35; A1F-20 G&J, -23C&D, -A2F-47; A2C-9B, -10A&B; A0W-44; IPS-106; AIKESWPS-85, -86.
