50-424/85-42 Attention: Mr. Roger D. Walker The Georgia Power Company wishes to submit the following information concerning the violation identified in NRC inspection report 50-424/85-42:

Violation 50-424/85-42-01; " Failure to Evaluate or Incorporate Manufacturer's Recommended Preventive Maintenance Measures for. Control Building Engineerin Safety Chillers in the Equipment Maintenance and Storage List (EMSL) gProgram" - Severity Level IV.

The violation identified a failure to follow construction field procedure GD-T-09 requirements to review vendor storage and maintenance recommendations and to incorporate them into the EMSL program or to document the discipline engineer's decision to exclude them. Manufacturer requirements to rotate the compressors for the Control Building Engineering Safety Features Chillers every two years were not incorporated into EMSL maintenance schedules and no records were available which documented a responsible discipline engineer's decision to exempt this requirement. Georgia Power Company offers the following response pursuant to the criteria of 10 CFR 2.201:

- 1. Georgia Power Company acknowledges the violation as identified in the NRC inspection report.

2. The violation is attributed to the following basic causes:

a. Engineers from different disciplines failed to adequately communicate information learned through contact with the vendor,

b. No method was established in the EMSL program to' inform en-gineers of changes in vendor maintenance requirements.

The original EMSL maintenance requirements for the Control Building chillers were established by a mechanical discipline engineer using the original vendor manual which did not require rotation of the g2] gob 4 G

ZEcl 3

g.

.w Paga Two comp'ressor motor shaft. An electrical discipline engineer contacted the vendor to inquire about periodic rotation of the compressor motor shaft and was informed that the shaft should be rotated every two years. The vendor followed-up this contact with a letter which was placed in the Supplier Document Register upon receipt at the site. The mechanical discipline engineer responsible for maintenance of. the chillers was not distributed a copy of the vendor's follow-up

- letter. The electrical discipline engineer who contacted the vendor apparently assumed that the vendor's letter would be forwarded to the party responsible- for incorporating the new requirement into the. EMSL program. However, since vendor maintenance requirements are very rarely changed, no method was established to ensure information' of this type was forwarded to the appropriate personnel.

When the omission of. the compressor rotation was discovered in early 1985, two Deviation Reports (MD-08008 and MD-08009) were generated to evaluate the condition of the chillers of the shafts rotated in February 1985 to resolve the Deviation Reports, there was no evidence that the chillers had been adversely affected by the lack of previous rotation. However, the requirement to rotate the compressor shaft was still not added to the EMSL maintenance schedules for the chillers until the violation was identified by the NRC inspector. ' This discrepancy is regarded as personnel error.

3. The rotation requirements have now been incorporated into the EMSL program. In addition, Georgia Power Company has established a.

consolidated single organization to be responsible for the equipment maintenance program. Rather than divide maintenance responsibilities among separate discipline engineers, the new Construction Maintenance Organization (CMO) is self-contained. This' should' eliminate communication and division of responsibility problems.

As part of the transition from the discipline method to the CM0, a review and re-evaluation of equipment maintenance schedules will be conducted and will include reconsideration of manufacturer / vendor maintenance requirements. Equipment maintenance schedules will be updated as necessary.

The CM0 has also been placed on distribution for transmittal forms for supplier. documents, which will alert CM0 engineers of any new or revised document submitted by vendors. CM0 engineers will review revised vendor documents and incorporate new or revised maintenance requirements as necessary.

4. The establishment of the CM0 should' prevent further violations.

5. The CM0's review and re-evaluation of equipment maintenance requirements are expected to be completed by April 30, 1986. All other corrective actions relative to the violation have already been completed.
