i ENCLOSURE 1 NOTICE OF VIOLATION Mississippi Power and Light Company Docket No. 50-416 Grand Gulf License No. NPF-29
)
During the Nuclear Regulatory Commission (NRC) inspection conducted on April 15 -
May 19, 1986, violations of NRC requirements were identified.
The violations involved inadequate procedures that resulted in exceeding the Technical Specifi-cation (TS) requirements and inadvertent safety equipment operation.
In accordance with the " General Statement of Policy and Procedure for NRC Enforce-ment Actions," 10 CFR Part 2, Appendix C (1985), the violations are listed below:
A.
TS 3.3.7.8 and TS Table 3.3.7.1-1 (Item 6) requires that with both chlorine detection channels or both control room ventilation monitors inoperable, within an hour initiate and maintain operation of at least one control room emergency filtration system subsystem in the isolation mode of operation.
TS 6.8.1 requires that the applicable procedures recommended in Appendix "A"
of Regulatory Guide 1.33, Revision 2,1978, be established and implemented.
Appendix "A" of Regulatory Guide 1.33 states that safety-related system procedures should include instructions for operation of control room heating and ventilation systems.
System Operating Instruction (SOI) 04-S-01-Z51-1 implements this requirement.
Contrary to the above:
1.
From 1:30 p.m.,
on April 23, 1986, until 7:00 p.m. April 25, 1986, the control room emergency filtration system (CREFS) was not operating in the isolation mode while both chlorine detection channels were inoperable and both control room ventilation monitors were bypassed.
This exceeded the limiting condition of operation for approximately 53 hours6.134259e-4 days <br />0.0147 hours <br />8.763227e-5 weeks <br />2.01665e-5 months <br />.
2.
System Operating Instruction 04-S-01-Z51-1 was inadequate in that conditions for operating the CREFS in the isolation mode were not defined.
Consequently, the CREFS was improperly removed from the isolation mode on April 23, 1986.
This is a Severity Level IV violation (Supplement I).
B.
TS 6.8.1 requires that applicable procedures recommended in Appendix "A" of Regulatory Guide 1.33, Revision 2, 1978, be established and implemented.
Appendix "A"
of Regulatory Guide 1.33 states that the Administrative Procedures for safety-related systems should be established.

Mississippi Power and Light Company Docket No. 50-416 Grand Gulf 2
License No. NPF-29 Paragraph 6.6.3 of Administrative Procedure (AP) 01-S-07-4 requires the responsible engineer to update the as-built drawing list and ensure they are distributed prior to returning the affected system to operation.
Paragraph 6.1.2 of AP 01-S-07-1 requires all maintenance work be accom-plished using written and approved work instructions and be authorized by approved maintenance work order or maintenance planning and scheduling system task card.
Contrary to the above:
1.
As of May 21, 1986, drawing M-1106A had not been updated to reflect design change package 84/4063 which was signed off as completed on February 21, 1986.
2.
On April 7,
1986, no documented instructions were utilized when attempting to reset trip units on the low-low set logic for safety /
relief valves resulting in the inadvertent lifting of safety / relief valve 1821-F0518.
This is a Severity Level IV violation (Supplement I).
C.
10 CFR 50, Appendix B, Criterion II and the accepted QA program, MPL-TOP-1A, requires indoctrination and trair.ing programs for personnel performing quality-affecting activities which assure that personnel performing quality-affecting activities are trained and qualified in the principles and techniques of the activity being performed.
Contrary to the above, trai.'ing of fuse indoctrination and identification was inadequate in that on April 30, 1986, while performing a tagout, an operator removed the wrong fuse resulting in the inadvertent startup of Division I combustible gas control system.
This is a Severity Level IV violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, Missiesippi Power and Light Company is hereby required to submit to this Office within 30 days of the date of the letter transmitting this Notice a written statement or explanation in reply including:
(1) admission or denial of the violation, (2) the reason for the violation if admitted, (3) the corrective steps which have been taken and the results achieved, (4) the corrective steps which will be taken to avoid further violations, and (5) the date when full compliance will be achieved. Where good cause is shown, consideration will be given to extending the response time.
