i These reviews were conducted to ascertain that facility operations were in conformance with regulatory requirements, Technical Specifications and i

Administrative Procedure fio.16 " Conduct of Operation, Operations Group".

Within the areas inspected two violations were identified:

,.

a.

On December 16, 1981, the manual isolation valve for the spray additive tank was found locked closed which disabled both trains of spray addition. The time period this system was inoperable is not known but is believed to be in excess of technical specification allowance of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. This is a violation of Section 3.6.2.2 of the Technical

'

Specifications which requires the spray additive system to be operable when the reactor is in ibde 1.

This incident was found by the licensee and was reported to the fiRC.

This violation is covered in f4RC Special Report flos. 50-348/81-31 and 50-364/81-34.

b.

On December 15-18, 1981, the licensee discovered, during performance of surveillance testing, that Unit 1 containment spray header nozzles were not installed in accordance with design drawings. The licensee identified the following discrepancies:

(1) Type "R" nozzles on headers SA and SB and type "T" nozzles on

headers 4A and 4B were found pointing toward the containment center line instead of the containment wall as specified in referenced drawings.

(2) All of the horizontally mounted nozzles of group types "B" and "0" on headers 1-A and 1-B were incorrectly mounted on the inboard side of the header rather than the outboard side. The nozzles were pointed down as specified.

(3) Two nozzles, a type "R" on header S-B and a vertical type "F" nozz!e on header 2-B, were not installed due to an apparent hanger interference. These descrepancies are attributable to the following:

d.

The piping fabricator made on error in developing detailed shop fabrication drawings and isometric drawings from the

Architectural Engineer (AE) design drawings.

b.

The error was not discovered by the piping fabricator during internal checks or by the AE or licensee audits.

c.

Piping was fabricated and inspected using the erroneous.

drawings.

!

d.

The piping was Q.C. inspected upon receipt by the licensee only for shipping damage and verification of proper quality assurance documentation.

i

.

.'.

..

,

e.

The containment spray header was installed but the spray header nozzles were not to be installed until after hydrostatic test completion by the construction completion and testing group. This generated a outstanding QC exception item pending spray nozzle installation and verification.

f.

Af ter hydrostatic test completion the system was turned over to the plant start-up group for functional testing with the QC exception outstanding.

g.

Prior to start-up preoperational testing the spray nozzles were installed on the spray ring.

This work was done without obtaining a Construction Work Request (CWR). This was not in accordance with the QC program. A QC verification of the nozzle installation was not performed, h.

QC procedures would have identified the discrepancy if the work had been performed under a CWR.

The inspection would have been performed against the AE design drawings which indicated proper norzle location and orientation.

i.

Approximately 4 months after the nozzles had been installed and the scaffcid to the spray ring header had been removed, a memo was written to Construction Mechanical QC by the Construction Piping Department stating that the spray nozzles had been installed.

This memo was to clear the outstanding QC exception regarding the nozzle installation.

J.

The applicable QC procedures were violated when QC accepted this memo in lieu of performing the required inspections.

This is a violation in that established procedJres were not followed as required by 10 CFR 50 Appendix B, Criterion V as implemented by paragraph 17.1.5 of the FSAR and Alabama Power Company Field Quality Control procedure No. 5.6.1.2 (Violation No. 50-348/82-02-01).

A meeting was held in Region II on Janaury 26, 1982 between Alabama Power Company (APC0) and NRC. The meeting was requested by APC0 to review the containment spray nozzle misalignment problem.

The licensee

,

presented evaluations concerning the impact of containment spray nozzle misorientation on the design basis containment temperature and pressure calculations and what could be experienced in the containment building during certain accident conditions. Additionally, the iodine removal coefficient with the spray nozzles in the as-found conditions was dddressed. The licensee concluded that the as constructed conditions have been analyzed and do not adversely affect the ability of the containment spray system to meet its intended function.

The licensee has reoriented the misaligned nozzles to conform with the design drawings.

NRC II has reviewed the liecnsee's containment spray header evaluation and conclude that the spray header installation errors do not represent real or eminent safety concerns.

8.

Unit 1 Outage

,

The inspectors toured various portions of Unit 1 to witness various maintenance activities, instrument loop response time testing and instrument cal ibra tion.

All activities were covered by appropriate procedures and with proper health physics surveys and control.

The inspectors observed plant housekeeping and fire protection activities and fire detection systems.

Security activities during the shut down were monitored for adherence to the security plan.

Within the areas inspected no violations or deviations were identified.

9.

Independent Inspection Effort The inspectors routinely attended meetings with certain licensee management and various shift turnovers between shift supervisors, shift foreman and licensed operators during the reporting period.

These meetings and discussions provided a daily status of plant operating and testing activities in progress as well as discussion of significant problems or incidents.

10.

Followup of Plant Incidents During the reporting period, the inspectors conducted followup activities on the fellowing:

a.

On December 22,1981, at 2:31 a.m. hours Unit No. 2 reactor tripped on low steam generator water level.

The trip was caused by a shorted diode which caused 2A steam generator feed pump to trip when the indicating lamp test push button was pushed to the test position.

The shorted diode was replaced and the unit was returned to criticality at 5:20 a.m.

b.

On January 8,1982 at 11:40 a.m. Unit No. 2 reactor tripped on low steam generator water level.

The trip occurred during the performance of turbine valve testing. While changing the turbine valve control from sequential to single valve control, oscillations in the turbine valves caused the steam generator water levels to shrink, causing the reactor to trip on low steam generator level.

The licensee has investigated the cause of the valve oscillations.

The licensee has monitored the turbine valves during succeeding testing but the cause of the valve oscillation has not been determine '

'

.

c.

On January 11,1982, at 9:09 a.m. Unit No. 2 reactor tripped due to main steam line high differential pressure.

This trip initiated safety injection. Engineered safeguards equipment operated as designed.

The trip was caused by excessive cold weather which had frozen a main steam pressure sensing line.

In the process of thawing and returning the instrument to service a high steam line differential pressure signal was generated.

The inspectors reviewed the circumstances involved in each incident and, where appropriate, the action taken by licensee management in response to the incident. The licensee's management activities appeared to be both timely and adequate in each case.
