1. Underwater Intrusion System
An underwater intrusion system protects a power plant using
a barrier system.54 Mr. Paduano testified that “The system
consists of a bridge across the intake canal with a suspension of
a barrier, and underwater and surface detection devices.” FPL
claims an ITC regarding the underwater intrusion detection system
for the 1990 taxable year.
On October 25, 1984, the NRC sent a letter to FPL concerning
St. Lucie’s physical security plan. The letter stated in
pertinent part:
Other changes which were in response to NRR’s
letter of June 5, 1984, relative to the Underwater
Intrusion Detection System (UIDS), are in need of
additional clarification. However, this additional
information request does not delay the acceptance of
your proposed UIDS. You should commence implementation
of that system upon receipt of this letter.[55]
In response to an FPL letter and a meeting regarding the
intake canal barrier and intrusion detection system, on November
14, 1985, the NRC sent a letter to FPL concerning St. Lucie Units
1 and 2 physical security plan. The letter stated in part:
We have determined that the proposal presented by
Florida Power and Light Company * * * is technically
insufficient in that the underwater portion does not
satisfy the requirements of 10 CFR 73.55(c)(4) * * *
54 Harry Paduano, a former manager with FPL, testified that
the underwater intrusion system was required by the NRC.
55 Mr. Paduano testified that this letter in effect required
FPL to modify the underwater intrusion system.
