SUBJECT:

SHEARON HARRIS NUCLEAR POWER PLANT - NRC SUPPLEMENTAL

INSPECTION REPORT 50-400/02-08

Dear Mr. Scarola:

On September 6, 2002, the Nuclear Regulatory Commission (NRC) performed a supplemental

inspection associated with a White finding identified in the mitigating systems cornerstone at

your Shearon Harris Nuclear Power Plant. The White finding involved a violation of your fire

protection program resulting from a Thermo-Lag fire barrier assembly (wall) which had an

indeterminate fire resistance rating. The NRC determined that portions of your corrective

actions to resolve this issue were appropriate. However, the NRC noted that your planned

corrective actions included the use of

ylr

m nual action as opposed to one of the protection

methods identified in NRC Position C.5.b.(2) of Branch Technical Position BTP)

Q -1.

As a result, e White iindng remainee

crrective

actions and the development of internal NRC inspection guidance in this area. The inspection

report documentinglris was transmitted to you on September 9, 2002.

Subsequent to the completion of the inspection, a Senior Reactor Analyst evaluated the risk

significance of the non-conforming Thermo-Lag barrier taking into consideration your corrective

actions accomplished to date. These actions included separating the auxiliary control panel

room, containing the Thermo-Lag fire barrier in question, from the B Train switchgear room.

This resulted in two separate fire areas, and reduced the ignition frequency of fires capable of

challenging the Thermo-Lag barrier by an order of magnitude. This translated into a

corresponding reduction in the core damage frequency and reduced the risk significance of the

degraded Themmo-Lag barrier to that of a Green finding. Based on this, the White finding will

be removed from the NRC performance summary effective the date of this letter. However,
