50-328 SEQUOYAH NUCLEAR PLANT (SQN) - NRC INSPECTION REPORT 50-327, 50-328/98 REPLY TO NOTICE OF VIOLATION (NOV) 50-327/98-03-02 This letter provides TVA's reply to the subject NOV dated April 10, 1998.

The NOV addresses the failure to report an adverse condition on a work request / work order or a problem evaluation report pertaining to a potentially high oxygen level in the pressurizer relief tank (PRT) and failure to initiate a work request / work order when a waste gas sample from the PRT could not be obtained.

The enclosure contains TVA's response to the NOV.

There are no commitments contained in this response.

If you have any questions regarding this response, please contact me at extension (423) 843-7001 or Pedro Salas at extension (423) 843-7170.

UNITS 1 AND 2 INSPECTION REPORT NUMBER 50-327, 50-328/98-03 REPLY TO NOTICE OF VIOLATION (NOV) 50-327/98-03-02 RESTATEMENT OF VIOLATION

" Technical Specification 6.0.1.a requires, in part, that procedures shall be established, implemented, and maintained covering activities recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978,

' Quality Assurance Program Requirements (Operations).'

Appendix A of Regulatory Guide 1.33, Section 1, includes administrative procedures.

Site Standard Practice SSP 3.4, Corrective Action, Section 3.0.A, requires personnel to 'promptly report adverse conditions on a work request / work order and/or a problem evaluation report (PER).'

j Contrary to the above, the licensee failed to report an adverse condition on a work request / work order and/or a problem evaluation report.

Specifically:

1.

Following analysis of samples taken on February 6 and 7,

1998, that indicated high concentrations of oxygen and hydrogen in the Unit 1 primary relief tank, the licensee did not initiate a PER Lo address this adverse condition.

2.

Following identification, in early February, that waste gas samples could not be obtained from the Unit 1 PRT without use of a high volume vacuum pump, the licensee did not initiate a work order / work request to address this adverse condition.

This is a Severity Level IV Violation (Supplement I)."

TVA's REPLY TO THE VIOLATION I

1.

Reason For The Violation 1

The reason for the violation was that involved Chemistry personnel failed to recognize the sampling problem as a condition adverse to quality.

The involved Chemistry personnel believed that problems E-1 J

should be investigated and clearly identified prior to initiation of the corrective action documentation.

. Chemistry personnel originally believed the problem was associated with the grab sample apparatus and sample pump.

They began investigating the problem and took actions to eliminate these potential sources of problems and verify the sample analysis results.

2.

Corrective Steps Taken And Results Achieved Chemistry personnel initiated a PER on March 13, 1998, to address the inability to obtain a valid sample from the pressurizer relief tank (PRT).

An investigation to determine the cause of the condition and corrective action is being performed.

l Plant personnel initiated a work request

(' R) on W

March 25, 1998, to address the inability to obtain a valid sample from the PRT.

During performance of the WR, it was determined that the pr. essure regulator was not working.

The pressure regulator prevented a i

sample from being obtained which confirms the original assumption that the condition was a sampling problem.

Appropriate plant personnel have been counseled on timely initiation of corrective action documents.

An increase in the number of PERs initiated by the Chemistry group has been noted.

The Chemistry area was reviewed to determine if other conditions existed that should be documented on a PER l

or WR.

No additional conditions requiring a PER or WR l

were identified.

Site management emphasized initiation of corrective action documents during the plan-of-the-day meeting and staff meetings.

This has stressed the importance of the Corrective Action Program and program implementation.

l 3.

Corrective Steps That Have Been Taken To Prevent Recurrence While we believe this issue to be limited, a site-wide campaign to increase awareness and sensitivity to initiating corrective action documents is ongoing.2 4.

Date When Full Compliance Will Be Achieved With respect to the violation cited, SON is in full compliance.

  • TVA does not consider this corrective action a regulatory commitment. TVA's Corrective Action Program will track completion of the action.
