This 60-day telephone notification is being made in accordance with the reporting requirements of
10CFR50.73(a)(2)(iv)(A) and
10CFR50.73(a)(1) for an invalid actuation (start) of the 1C
Emergency Diesel Generator (
EDG).
On November 13, 2007, at 1013 hours0.0117 days <br />0.281 hours <br />0.00167 weeks <br />3.854465e-4 months <br />, while performing the replacement of an indicating bulb on the 1C EDG local start/stop CMC switch (a turn to stop/start switch) the switch was pushed inward making up the start contact and causing an inadvertent start of the 1C EDG. The EDG started but did not load since this was not a valid demand for operation of the 1C EDG. The 1C EDG was shutdown in accordance with operating procedures and returned to its normal standby status. The local start/stop switch was replaced and the removed switch was examined. The removed switch was determined to be missing a cardboard collar on the shaft of the switch that prevents inward movement. Lack of the cardboard collar did not inhibit the turn to start/stop function of the switch.
The licensee will notify the NRC Resident Inspector, State of
New Jersey, State of Delaware, and local government agencies.
