Exit Interview The inspection scope and findings were summarized with the Site Project Manager on February 9,13, 20, and 27,1981.

Licensee Action on Previous Inspection Findings (0 pen) 518, 519, 520, 521/80-18-01, Infraction - Failure to Take Timely Corrective Action on Drawing Control Findings.
In response to a Confirm-ation of Action Letter from NRC-RII dated January 30, 1981, the site QA unit completed a comprehensive re-audit of construction and vendor drawings for Hartsville.
Approximately three percent of the 113,000 safety-related drawings surveyed had been superceded.
The licensee reported to NRC-RII the results of their preliminary analysis with respects to the root causes of the adverse findings and outlined proposed corrective actions regarding reorganization and procedural changes for the Hartsville Nuclear Plant.

Unresolved Item One unresolved item pertaining to preventive maintenance of Unit B-1 reactor pressure vessel which is stored near the river unloading dock is discussed in paragraph.

5.
Independent Inspection Effort The inspector made surveillance tours during which the status of project work was noted, and construction activities were inspected on nuclear safety-related structures,' systems and facilities.
The inspection effort was concentrated on Plant A areas, but outlying structures were covered.
Instrumentation:
With the instrumentation QC supervisor, the inspector inspected stored instruments and prefabricated electrical and mechanical i
instrumentation and control panels in two warehouses. The purpose of the inspection was to verify that security, damage. protection and controlled environment were being provided.
Reactor Pressure Vessels (RPV): A-1 and A-2 RPV's have been installed on their pedestals and are in a " hold" status.
The inspector verified that
access is secured, that measures to protect them from construction damage
-
have been taken, and that each is being humidity controlled by circulation of warmed air as required by Receipt Inspection and Storage and Preventive Maintenance Procedure (RIS&PM-M650)
.
The B-1 RPV is in field storage near the unloading dock.
A reinforced plastic cover has been installed. The inspector found that warmed air was not being circulated but that a dehumidifier had been installed.
The mechanical project engineer explained that the fan and heater previously used had repeatedly " burned out".
The licensee had obtained verbal approval
'
from General Electric to substitute a dehumidifier.
The licensee had entered the vessel and verified that the internals were dry. The inspector informed the mechanical project engineering supervisor that a formal, written procedure should be prepared and approved by GE and the site
,
construction engineer.
This matter will be carried as unresolved item (519/81-03-01) until the revised preventive maintenance procedure is
.
formalized.

I l
Concrete:
Forming, installation of rebar, positioning of embedments, l
placements and post placement curing were inspected as work progressed in the Plant A fuel buildings, auxiliary buildings, control buildings, and j
essential service water pump houses. Completed concrete and new forming were l
inspected in the intake pumping station.
Repairs to concrete in the recently placed Unit A-1 weir wall were inspected.
Specific placements inspected included A2-A180, IPS-118, A2-KESWPS-#72 and #39, A2A-13D, and concrete filling of the A-1 biological shield wall between azimuths 19* and 187*.
Numerous cadwelds were made in this period joining #18 rebars to sleeves on top of the A-1 vent wall and to vendor installed sleeves on penetration frames #6 and #9 for the drywell above the vent wall. The inspector veri-fied that installation requirements of Enrico Products Company, manufacturer of the cadweld hardware components were being met.
.
During inspection of activities for structural concrete in these areas, conformance with the requriements of C. f. Braun Specification 300-01,
.
.
.
Revision 8, " Concrete", TVA Construction Specification G-2, QCI C-201, Rev.
4, and C.E.P. 9.02, Rev. 5, was verified.
Piping: The inspector verified that piping assemblies stored near and in the power block structures and those being installed were kept adequately capped as required by Quality control Instruction (QCI-M-210) and Standard Operating Procedure (SOP-27).
The presence of mechanical and welding inspectors in work areas were verified.
Open Items Control: Newly issued nonconformance reports, (NRC), significant quality control inspection reports (QCIR's) and QA unit audit findings were reviewed for pertinence to the inspection program.
In the areas inspected, no violations or deviations were identified.

Licensee Identified 50.55(e) Items a.
Previously Identified Items (Closed) 518, 519, 520, 521/80-15-03, Drawing Control Def.iciency (Audit HT-G-80-12). This item is closed by infraction 518, 519, 520, 521/80-18-01. A comprehensive re-audit from January 19, through February 26, 1981, disclosed continuing deficiencies as discussed in paragraph 3 of this report.
This re-audit responsed to audit HT-G-81-06 and audit HT-G-80-12 and NRC-RII Confirmation of Action letter dated January 30, 1981.
(Closed) 518/80-18-05, Inadequate Support of Condensate Header. C. F.
Braun drawing SN-310123, Revision 2, was issued October 10, 1980. This revision provides a support saddle and spreader plate at each support beam to eliminate overstresses in the pipe wall.
All condensate headers at Hartsville will be supported by this revised type stress spreading assembly.
b.
Newly Identified Items (0 pen) 518, 519, 520, 521/81-03-02 Completion of As-Built Drawings (HTRD-50-518, 519, 520, 521/81-04).
The licensee's first interim report cites three separate deficiencies:
(1) QA program requirements have not been translated into procedures.
(2) Contract requirements for completion of as-built drawings by C. F.
- Braun after the 300-hour test.
This is at variance with QA program requirement for completion before operational testing and transfer of system to nuclear power.
(3) Design changes identified on field change requests are not in-corporated into drawings until after the 300-hour tes.,
o
-
The licensee is committed to submitting additional information on these deficiencies by April 1,1981.
(0 pen) 518, 519, 520, 521/81-03-03 Deficient Drawing and Docueant Control (HTRD-50-518, 519, 520, 521/81-05). Reference infraction 518, 519, 520, 521/80-18-01 7.
