NRC COMMENT:

RESPONSE TO THE NOTICE OF DEVIATION ITEM REPORTED DURING NRC INSPECTION CONDUCTED ON NOVEMBER 16-19, 1987 INSPECTION REPORT NOS. 50-280/87-32 AND 50-281/87-32 The following deviation was identified during a Nuclear Regulatory Commission (NRC) inspection conducted on November 16-20, 1987.

By letter dated June 29, 1984 (Serial No. 095A) the licensee informed the NRC that "at the specific operation task level a detailed review of each high level step would be performed during the revision upgrade from the generic emergency response guidelines (ERG) to plant specific procedures."

The licensee informed the NRC that specific forms would be utilized to provide cross-reference capabilities between plant specific steps and the ERG steps from which they are derived.

The letter further states that as appropriate, entries on these forms identify and justify deviations of deletions/additions on sequencing and significant deviations to step content, other than minimum wording.

Contrary to the above, for EP-l.02A, Natural Circulation Cooldown, Rev. 1, the licensee has not provided adequate written justification in the step deviation document where EP-l.02A deviates from Revision 1 of the Emergency

Response

Guidelines.

Specifically, for the reduction of sub-cooling margin as a

result of the Reactor Coolant

. System depressurization to establish residual heat removal flow.

RESPONSE

RESPONSE TO NOTICE OF DEVIATION INSPECTION REPORT NOS. 50-280/87-32 AND 50-281/87-32 (I)

ADMISSION OR DENIAL OF THE ALLEGED DEVIATION Virginia Electric and.Power Company acknowledges that for EP-l.02A there is a deviation from the Procedure Generation Package for failure to provide adequate written justification in the step deviation document where EP-1. 02A deviates from Rev. I of the Emergency Response Guidelines.

(2)

REASONS FOR DEVIATION Written justification for the deviation from Rev.

I of the Emergency Response Guidelines (ERGs) was provided within the setpoint document for the Emergency Operating Procedures (EOPs).

Failure to document this deviation in the step deviation document was caused by.improper cross referencing with EOP support documents.

(3)

CORRECTIVE STEPS WHICH HAVE BEEN TAKEN AND THE.RESULTS ACHIEVED The EOP support documents have been reviewed to ensure proper documentation is available to support t-he deviation from the. WOG ERGs.

The step deviation document has been updated to provide the proper cross-reference to the EOP support documents.

(4)

CORRECTIVE STEPS WHICH HAVE BEEN TAKEN TO AVOID FURTHER DEVIATIONS The balance of the EOPs and the setpoint package will be reviewed during the next review cycle to ensure that deviations from WOG ERGs are properly documented in step deviation documents.

If any cases of inadequate documentation are identified as part of other revisions being made to the EOPs, they will be addressed as they are identified.

In order to clarify the relationship between the step deviation documents and the' setpoint package, the step deviation documents will be annotated to reference the setpoint package as appropriate.

(5)

THE DATE' WHEN FULL COMPLIANCE WILL BE ACHIEVED

~,:..,*,~-

EP-I. a:i'A: is in compliance with the Procedures Generation Package.

The review-ic:,f the remaining EOPs and cross-referencing of the step deviation document to the setpoint package will be completed by March 1989.

This corresponds to the completion date for revising the EOPs to incorporate changes identified in Revision IA of the WOG ERGs.

NRC COMMENT RESPONSE TO NOTICE OF VIOLATION ITEM REPORTED DURING RRC INSPECTION CONDUCTED ON NOVEMBER 16-20, 1987 INSPECTION REPORT NOS. 50-280/87-32 AND 50-281/87-32 During the Nuclear Regulatory Commission (NRC) inspection conducted on November 16-20,

1987, a violation of NRC requirements was identified.

In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1987), the violation is listed below:

10 CFR SO, Appendix B, Criterion V requires that instructions, procedures, and drawings shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished.

Technical Specification 6.4 requires that detailed written procedures with appropriate check-off lists and instructions be provided for actions to be taken for specific and foreseen malfunctions of systems or components including alarms, primary system leaks and abnormal reactivity changes.

Contrary to the above, the procedure utilized by the licensee for Natural Circulation Cooldown, EP-1.02A,* Rev. 1 is inadequate in that the cooldown curve referenced as Attachment 2 in the procedure, is less conservative than the Technical Specification heatup/cooldown curve, Figure 3.1-1.

This is a Severity Level IV violation (Supplement I).

RESPONSE TO NOTICE OF VIOLATION INSPECTION REPORT NOS. 50-280/87-32 AND 50-281/87-32

RESPONSE

(1)

ADMISSION OR DENIAL OF THE ALLEGED VIOLATION The violation is correct as stated.

(2)

REASON FOR VIOLATION During the development of the Emergency Operating Procedures (EOP), it was assumed that the heatup/cooldown curve contained in the Technical Specifications was based on average RCS temperature (T

). It was desired to present limits based on RCS cold leg temperature i~vgthe EOPs.

For natural circulation conditions, a core delta T of 30° was assumed.

Therefore, the Technical Specification curve was shifted 15° to the left to derive the cold leg curves for the EOP.

It has subsequently been determined that RCS cold leg temperature is the basis for the Technical Specification curve which makes the cooldown curve contained in EP-1.0ZA non-conseryative with respect to Technical Specifications.

(3)

CORRECTIVE ACTIONS WHICH HAVE BEEN TAKEN AND THE RESULTS ACHIEVED A temporary procedure change was prepared and approved by the Station Nuclear Safety and Operating Committee to direct the operator to use the cooldown curve located in the Operator Curve Book which is equivalent to the curve in Technical Specifications.

Engineering has been directed to prepare a

curve for use in the Emergency Procedures.

Also, a Technical Specification change request has been submitted which indicates the cooldown curve is based on the RCS cold leg temperature.

(4)

CORRECTIVE ACTION WHICH WILL BE TAKEN TO AVOID FURTHER VIOLATIONS Emergency procedures EP-1.0ZA and EP-l.02B will be revised to include the correct cooldown curve.

(5)

THE DATE WHEN FULL COMPLIANCE WILL BE ACHIEVED The 31, procedures EP-1.0ZA and EP-1.0ZB will be revised by* March
