PLANNED MAINTENANCE ON MlSHlCOT SUBSTATION BY WPS RESULTS IN GREATER THAN 50% SIREN COVERAGE LOSS
"On March 4, 2008, at 0100 CST, ten emergency notification system sirens in the Kewaunee Power Station Emergency Planning Zone (one in Kewaunee County, nine in Manitowoc County) were de-energized due to a planned power outage. The loss of power to these emergency notification sirens resulted in a lost population coverage of 51.2%. As a result, this event is being reported under 10 CFR 50.72(b)(3)(xiii) and guidance in NUREG-1022 as a major loss of off-site communications capability.
"The expected duration of the planned power outage is 2 hours. Kewaunee and Manitowoc County Emergency Management agencies have already established appropriate contingency measures for the planned loss of the emergency notification system. Contingency measures include route alerting and an available plane with loud speaker for the areas affected by the power outage. The State of Wisconsin and the Federal Emergency Management Agency were previously informed of this planned outage.
"The NRC Resident Inspector has been notified."

ERDS LINK DETERMINED INOPERABLE FOR 3 HOUR PERIOD
"On 3/04/08 at 0816 EST, the Control Room was notified that the ERDS Link was inoperable from 1815 to 2115 EST on 3/03/08.
"During the troubleshooting it was discovered that a fuse was blown on the ERDADS I/O Subsystem Chassis. The ability to activate the ERDS Link is done by the Tesselators which were locked up due to the blown fuse. Removing power fuse for inspection and replacing was completed, chassis resumed normal functions. The ERDS link was returned to operable 3/03/08 at 2115 EST.
"Initial determination did not correctly identify the loss of ERDS Link functions. Upon later review by Engineering, it was determined that the link was inoperable during the 3 hour period."
The licensee informed the NRC Resident Inspector.
