SUBJECT:

NRC VERTICAL SLICE INSPECTION AT BROWNS FERRY NUCLEAR PLANT, UNIT 2

'he NRC will perform a vertical slice review at your Browns Ferry Unit 2

'acility.

The inspection is scheduled for the weeks of November 27 and,

,',. December, 11, 1989, with the exit currently scheduled for December 20, 1989.

,'.The objectives of this inspection, major areas being reviewed, required,

'nformation, and the inspectors currently planned for the team are identified in the',enclosure.

a The system selected for review is the Core Spray (CS) system.

Interfaces with other systems will also be evaluated as necessary.

A single train outage may be'ecessary in order to perform cable signal tracing.

'The NRC team leader will meet with members of your Browns Ferry staff in late

"."October to provide the list of components to be verified and the type of information to be provided in order to expedite this review.

We also request, at that time, a detailed list of all outstanding work on the system with a br ief narrative description of each outstanding item.

If you have any questions regarding this activity, please contact Mr. W. Little at (404) 331-5525.
