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 local manual actions as opposed to one of the protection
methods identified in NRC Position C.5.b.(2) of Branch Technical Position (BTP) CMEB 9.5-1.
As a result, the White finding remained open pending further NRC review of your corrective
actions and the development of internal NRC inspection guidance in this area. The inspection
report documenting this 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 Thermo-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,
Violation (VIO) 50-400/02-08-01: Failure to Implement and Maintain NRC Approved Fire
Protection Program Safe Shutdown System Separation Requirements, remains open pending
further NRC review of your corrective actions and the development of internal NRC inspection
guidance in this area. Please inform us when your corrective actions are sufficiently complete
to permit our inspection.

Publically Available Records (PARS) component of NRCs document system (ADAMS).
