Chicago Tribune | Low-level emergency at nuclear plant: "Low-level emergency at nuclear plant

Published February 25, 2006

ROCKFORD -- A low-level emergency was declared Friday at Byron Nuclear Generating Station near Rockford after smoke caused by an electrical problem filled a tunnel in a protected area of the plant, Exelon officials said.

An "unusual event," the lowest of four Nuclear Regulatory Commission emergency classifications, was declared at 8:54 a.m., officials said. It ended at 11:09 a.m.

It started when smoke filled a tunnel that carries a pipe running from a backup cooling-water supply tank to the reactor, Exelon Nuclear spokesman Craig Nesbit said. Workers turned off electricity to the room, and the smoke ceased, he said.

Electrical equipment--a small pump, heater or breaker--in the room was "sparking and smoking," Nesbit said. There were no radiation releases, injuries or damage to safety-related equipment, and plant operations continued normally, he added.
