  • Attended exit interview on March 6,1980 2.

Management Interviews Monthly inspection scope and findings were summarized on March 6, 1980, with the site manager.

Weekly resident inspector's findings were discussed with the Site Project Manager on January 28, February 8, and February 20, 1980.

3.

Licensee Action on Previous Inspection Findings (Closed) Unresolved Item (518, 519, 520, 521/79-27-04), Excessive Backlog of QCIR's Awaiting Disposition and Closure The licensee has made substantial progress in reducing the backlog of safety related items. At a February 6, 1980 meeting with the site manager, construction engineers and planning supervisor, the licensee stated that the weekly computer printout of QCIR's will be separated into safety-related and non-safety related listings and that those listings will be broken down to functional listings for areas of responsibility to improve their useful-ness in these areas.

This matter will continue to be monitored on routine inspections by the inspector to assure the backlog does not start increasing.

Unresolved Items Unresolved items were not identified during this inspection.

5.

Independent Inspection Effort i

Licensee's organizational changes, accomplished and proposed were a.

discussed with site management and reviewed for compliance with the i

PSAR Section 17, the QA Manual and Construction Engineering Procedures.

A chart of reorganized site construction areas was issued in this

report period which combined the STRIDE and BOP work forces under one construction general superintendent. No adverse impact on quality is discernable from these changes.

i

b.

The inspector reviewed a January 20, 1980 status report of the site QA group's audits with QA Unit supervisors. The audits are being performed in a scheduled and orderly manner. Negative findings are transmitted to management and discussed with responsible parties. An apparently unacceptable lag in corrective actions in some areas was noted and will be pursued by the inspector during future inspections. This is identified as IFI 50-518, 519, 520, 521/80-05-01.

SOP-27 "HNP ASME III Piping Progran, Revision 1," and Construction c.

Engineering Procedure CEP 9.08 " Process Control" were reviewed. The documents appear to be adequate.

No items of noncompliance or deviations were identified.

Licensee Identified 50.55(e) Items

,

a.

Status of Previous Licensee Identified Items j

(Closed) 519/79-13-01 Use of Incorrect Concrete Mix in Unit 1 Shield Building Wall (NCR HNP-B-023). The licensee's final report on this j

matter was transmitted March 19, 1980. The compressive strengths of three cylinders at 180 days averaged 4392 psi. A cylinder tested at 270 days yielded 3697 psi or 7.6% below the 4,000 psi design criterion.

The results are acceptable under the tolera:ees allowed by the governing i

codes, ACI 301-72 (Section 17.2) and ACI 318-71 (Section 4.3.3).

(0 pen) 519/80-03-01 Unit B-1 Unacceptable Drywell Vent Structure Radiographs (NCR HNPA-089). The licensee's final report, which was transmitted February 15, 1980, committed to " remove and repair all defects which are apparent on the McManus RT film. Then, TVA will examine with 100 percent RT,...and make any further repairs necessary...".

The B-1 vent wall sections are being installed in Unit i

A-2 containment, due to delay of Plant B and acceleration of Unit A-2.

This item remains open pending review of the corrective action.

(Closed) 518, 519, 520, 521/79-27-06 Grit Blasting of Fabricated Piping Assemblies (NCR ENP-A-068). The licensee's final report was transmitted January 31, 1980. Piping elbows damaged by blasting without a diffuser nozzle have been replaced.

A new control proceddre, SOP-48 " Blast Cleaning and Surveillance Requirements for Pipe", Rev. I was issued February 5, 1980.

b.

New Items Reported by Licensee (Open) 518/80-05-03 Defective Welding by Industrial Engineering Works (IEW) on Unit A-1 RPV Shield Wall On the connections between separator-stiffener plates and the inner and outer plates of the shield wall, TVA found numerous instances of lack of full penetration along the backing bars. TVA's stated position is that they will make the necessary corrections. The IEW representa-tive who investigated at the site disclaimed contractual responsibility.

(0 pen) 518, 519, 520, 521/80-05-02 Wiring Discrepancies on High Pressure Core Spray (HPCS) Components (NCR's HNP-A-084, HNP-A-085, and HNP-A-086)

,

Discrepancies have been found on the HPCS diesel generator (DG) control switchgear, HPCS motor control centers and HPCS DG air compresser SKID assembly. These discrepancies are in addition to those tracked under Item 518, 519, 520, 521/78-08-03, involving incorrect terminations, errors in wiring diagrams, missing wires, and mislabeling. A GE and Morrison-Knudson task force is scheduled to correct the switchgear and air compressor SKID assembly at Hartsville.

Corrective actions on the motor control centers has not been determined.

Containment (Steel Structures and Supports) - Review of QA Implementing Procedure - Unit A-2 Work Package D-256-M1 Reactor Pressure Vessel Pedestal - Prepare and Pour Pedestal, Plant A, Unit 2, through Addendum No. 17, and Work Package No.

D-260-C1 with Addendum No. 1 Plant A-2 "P/P (Prepare and Place) Drywell Vent Structure" were reviewed for hold points, approvals, reference drawings, etc.

The review disclosed no items of noncompliance or deviations.

portion of the RPV pedestal and the drywell vent structure assembly against the controlling procedures and drawings discussed in paragraph 7.

No items of noncompliance or deviations were identified.

9.

Reactor Vessel Installation - Unit A-1, Observation of Work and Work Activities Work package D-030-M5 detailed the final setting of the RPV. The procedure for torquing the bolts attaching the RPV to its pedestal were augmented by shop calibration of the Pilgrim torquing tool. At the specified loading of 500,000 pounds, a permanent strain of 3 to 4 mills occurred on the test bolts. The inspector observed torquing of pairs of the hold down bolts to the specified loading. Machined leveling shims prevented metal seizure and spalling.

No items of noncompliance or deviation was identified in the operation observed.

11.

Extended Construction Delay - Plant B The inspector reviewed the memoranda " Plant B - Closedown Remaining Work" published during this inspection period. The memoranda detail the status of " moth balling" work.

The licensee has not published adequate procedures detailing protective and surveillance activities for the intervening period prior to resumption of work on Plant B.

Following discussions with the B0P construction engineer and the supervisor of the site QA unit, a joint memo to project engineering and quality control supervisors was issued. The memo stated in part:

" Attached is a list of all "open" work packages for Plant B.

Make every effort to close out all work y ackages for which your unit has responsibility.

If you cannot close them out, prepare a list of remaining work ~ packages for your unit".

This item is designated as inspector follow up item 50-519/80-
