Violation 370/88-20-01 A. Technical Specification 6.8.1 requires that written rocedures be

, established, implemented, and asintained covering th ictivities  ;

, recommended in Appendix A of Regulatory Guide 1.33 Rg tsion 2,  !

yebruary 1988.  !

l t Regulatory cuide 1.33, Revision 2, February 1978. Appendix A. requires that procedures be written, implemented, and raintained for energining, filling, draining, startup, shutdown, and changing modes of operstion of l safety related systems. ,

McGuire procedure OP/2/A/6350/05, AC Electrical Operation Other than l Normal Lineup, specifies the nethod to be used to allu 6900 volt i i switch gear assemblies to their alternate power supp. . ,.

sequence of the steps involved in repositioning the equipment and ,

4 1. Admission or denial of violation ,

i ne violation is admitted as stated.

2. Reason for the violation if adeitted:

) i j The IAE Technician involved risinterpreted plant data. }

Also, the Operating Procedure for draining the steam generators, p

O .

Attachment No. 1 Page 2 Steam Generator Cold Wet Layup Recirculetion (OP/2/A/6250/03A), did not include steps to defeat the Steam Generator Low Low Lovel setpoint ESF actuation, even though this action is neces?ary and performed every time prior to draiaing the Steam Generators.

3. Corrective steps which have been taken and results achieved:

Operations personnel implemented a change to procedures OP/1&2/A/6250/03A, Steam Generator Cold Wet Layup Recirculation, which now include steps for IAE personnel to defeat the Otrer Cenerator few Low Level ESF actuation prior to draining a steam generator. Also, procedures OP/1&2/A/6100/01, Cont' tolling Procedure for Unit Startup, were revised to include steps to verify the Steam Generator Low Low Level ESF Actuation is reinstated prior to entering Mode 4 (Hot Shutdown).

4. Corrective eteps planned to avoid further violations:

t' Procedures OP/1&2/A/6250/03A, Steam Generato- Cold Wet Layup Recircu!.ation, will be revised to clarify the ,' ap to defeat all Feedwater Isolation signals. The clarific.cion will specify which Feedwater Isolation signals are to be defeated.

5. Date when full compliance will be achieved:

October 1, 1988 Example No.2 Contrary to the above, proced.re OP/2/A/6350/03, AC Electrical

, Operation Other Than Normal Laneup, wr.a not properly implemented in that an incorrect electrical lineup of the Unit 2 6900 volt switch gear assemblies was made on June 24, 1988 which resulted in a loss of s,11 ,

Unit 2 off site power. In preparation for maintenance on the 2B off-site busline, a reactor operator incorrectly aligned all four 6900 volt switch gear assembifes to the 2B off-site busline instead of the 7A off-site busline as intended by the procedure. When the 2b cusline was subsequently 'temoved from service, a loss of all off site power occurre), .aasinc an Engineered Safety Feature actuation.

Reply to Example No. 2: l

. 1. Admission or denial of violation:

The violation is admitted as stated. ,

2. Reason for the violstien if admitted:

The Operations personnel involved mistakenly powered all four 6900 V. switchgear assemblies from 2B busline prior to de-energizing 2B busline for work. The action taken by the individual involved was inadvertently directed toward the s cong goal because he performed the opposite action than he L had intended to perform. The individual is an experienced operator who was fully qualified to perform this task.

3. Corrective steps which have been taken and results achieved:
a. Normal off-cite power was restored to Unit 2 by 1037 on June 24, 1988.
b. Operations management personnel have reviewed this incident with a representative from each shift.
c. Operations reviewed Procedure OP/2/A6350/05 for possible enhancement, and determined that with the number of possible variations of alignment, a revision would not be practical and probably would not have  !

pre 'nted this incident from occurring.

4. Corrective steps planned to avoid further violationst, No additional steps are required.
5. The date when full compliance will be achieved:

McGuire is in full compliance at this time.

Example No. 3 ,

Contrary to the above, Removal and Restoration (R&R) procedure 26-616, Tagout for busline 2B, was inadequate in that it did not direct the sequence of steps required to operate the 2B busline Primary Circuit Breakers when the 2B off-site busline was removed from service on June 24, 1968.

There 3 examples constituta e severity level IV (Supplerent I) violation and apply to Unit 2.

j Reply to Example No. 3:

1. Admission or denial of violations i The violation is admitted as 6tated.
2. Reason for the violation _1f _admittedt l

Operations staff personnel felt that the generic procedure along with the verbal instructions given with the R&R were sufficient to l accomplish the desired alignment; however, thic was not the case.

l

3. Corrective steps which have been taken and results achieved
a. Normal off-site power was restored to Unit 2 by 1037 on June 24, 1988.
b. Operations management personnel have reviewed this incident with a representative from each shift.

4. Corrective steps planned to avoid further violations:

A meno.will be written and sent to all Operators emphasizing that the R&R is to allow the removal and restoration of equipment in a specific manner by directing the sequence of the steps involved in repositioning the equipment and indicating the desired removal and return position.

5. Date when full compliance will be achieved l September 30, 1988 i

Violation 369,370/88-20-02 ,

B. Technical Specification 6.2.3.3 requires the Station Safety Review Group maintain surveillance of plant ectivities to provide

independent verffication that these activities are performed correctly and that human errors are reduced as much as possible.

Contrary to the above, a review of McGuire Safety Review Group (MSRG) activicies covering the period of 198t through June 1988

  1. revealed that the MSRG did not perform routine independent surveillance of plant operations a* i maintenance activities to [

provide independent verification that these activities were performed correctly. '

This is a severity level IV (Supplement 1) violation ard applies tu both units.
