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,
