SUBJECT: NOTICE OF VIOLATION

.(NRC INSPECTION REPORT NO. 50-327/98/01 AND 50-328/98/01)

Dear Mr.- Zeringue:

This refers to the inspection conducted on January 26-30, 1998 and

February 9-13. 1998. at your Sequoyah facility. This was a Safety System

Engineering Inspection (SSEI) of the Auxiliary Feedwater (AFW) system. The

enclosed report presents the results of that inspection.

1The overall performance capability of the AFW system was assessed as good with

no operability concerns identified with this system. Based on the results of

the inspection, the NRC has determined that a violation of NRC requirements

occurred. A violation was identified for failure to perform a 10 CFR 50.59

Safety Evaluation for changes made to the 2A-A motor driven AFW pump during

maintenance which changed the rotating element. This violation is of concern.

because it indicates that your reviews of the changes had too high of a

threshold for 10 CFR 50.59 evaluations and your reviews did not account for

the changes made to the facility as described in the Final Safety Analysis

Report.

The SSEI' team identified an Unresolved Item (URI) concerning an unverified

FSAR Chapter 15 Accident Analysis assumption for 10 minute operator action on

a Main Feedwater piping rupture. You are requested to respond to this issue.

Please provide the basis which demonstrates that FSAR Chapter 15.4.2.2. Major

Rupture 'of Main Feedwater Piping. ten minute operator action assumption to

isolate the AFW from the faulted steam generator is met or is not required.
