DPR-52 During the Nuclear Regulatory Commission (NRC) inspection conducted on November 15, -

December 18,

1989, two viola.ions of NRC requirements were identified.

The first violation involved failure to comply with plant procedures for operator response.

The second violation was for failure to initiate Condition Adverse

.o qua',ity Repo'-s (CA(}Rs) for tes deficiencies when "repair", and "accept as is" actions were considered.

In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions,"

10 CFR Part 2, Appendix C ( 1989),

the violations are )isted below:

DPR-52 design

placed, on a

CAQR if "accepted-as-is" or "repair" actions are being considered.

Site Directors Standard Practice

3. 13, Corrective Action, implements the NQAM requirements.

Contrary to the

above, the following two examples of test deficiencies which involved "repair" and "accept-as-is" activities were not addressed as conditions adverse to quality.

During performance of Restart Test Procedure 2-BFN-RTP-031A, Control Bay Heating Ventilation and Air.Conditioning, the Unit 1

and Unit 2 Control Bay chill water'lows failed to meet the acceptance criteria.

The deficiencies were documented by Test Exception TE-07.

The test exception was closed with a

repair activity, through temporary modification TACF 0-88-002-031, without initiation of a

CAQR.

2)

During performance of post modification test PMT-161, after installation'f new shutdown board room emergency cooling units for shutdown board rooms C

8 D,

the cooling units tripped prior to obtaining-. the required. test data for the cooling capacity calculations.

Because of this, the acceptance criteria could not be verified.

Test exception EN-8 was written and dispositioned as acceptable without meeting the acceptance, criteria because the test would require'dditional heat load to be added in the room.

Although previous testing of the old cooling units had been conducted using Technical Instruction TI-81, Shutdown Board Room Emergency Cooling System Performance Check, this test exception was dispositioned wit',hout issuance of a

CAQR for an "accept as is" condition.

The shutdown electrical boards are required to be

'operable by plant Technical Specifications 3.9.A, since they provide electrical power to equipment used to mitigate accidents.

This is a Severity Level IV violation (Supplement-I) and is applicable to Unit 2.

Pursuant to the provisions of 10 CFR 2 '01, you are hereby required to submit a wr'itten statement or explanation to the Nuclear Regulatory Commission, ATTN:
