SUBJECT: NRC INTEGRATED INSPECTION REPORT 50 327/97 01 AND 50 328/97 01

AND NOTICE OF VIOLATION ,

i

Dear Mr. Kingsley:

l

l This refers to the inspection conducted on January 19 through March 1,1997 at i

i the Sequoyah facility. The enclosed report presents the results of this

inspection.

During the inspection period, your conduct of activities at the Sequoyah

,

facility were generally characterized by good operations and maintenance.

l Operators responded appropriately to a turbine runback event and to a decrease

, in condenser vacuum event. Maintenance exhibited good performance in  ;

! addressing emergent issues during planned emergency diesel generator outages  !

l and in improving the switchyard predictive maintenance program. However, the ,

NRC is concerned with continuing 3roblems associated with the heater drain t

tank level control system and tur)ine runback circuitry which resulted in a  ;

l demand for a runback and an unexpected runback response.  ;

Based on the results of this inspection, the NRC has determined that a ,

, violation of NRC requirements occurred. Several examples of an inadequate

alaric response procedure were identified. The violation is cited in the l

!

enclosed Notice of Violation (Notice) and the circumstances surrounding it is

described in detail in the subject inspection report.

,

You are required to respond to this letter and should follow the instructions l

specified in the enclosed Notice when preparing your response. The NRC will '

use your response, in part, to determine whether further enforcement action is

necessary to ensure compliance with regulatory requirements.
