OFFSITE NOTIFICATION INVOLVING A LOGGERHEAD TURTLE FOUND IN THE INTAKE CANAL
"At 1115[EDT] on 4/8/01 a notification was made to the Florida Fish and Wildlife Conservation Commission regarding a live Loggerhead Turtle found in the intake canal. The turtle will be sent off site to a rehabilitation facility. The notification to a state government agency requires notification to the NRC."
The licensee informed the NRC resident inspector.

BOTH EMERGENCY DIESEL GENERATORS DECLARED INOPERABLE
"Both Division 1 and Division 2 standby diesel generators were declared inoperable. This report is being made per 10CFR50.72(b)(3)(v)(A), in that both standby diesels were in a condition such that they may not have been able to fulfill their intended safety function.
"The division 1 diesel generator was declared inoperable because both diesel generator room exhaust fans were found rotating backwards. The division 2 diesel generator was declared inoperable due to one exhaust fan rotating backwards and the outside air temperature exceeding 72°F. The cause of the fan blades' reverse rotation is under evaluation. Reverse fan blade rotation may cause longer in-rush starting currents which could cause the fan motors to trip.
"With two diesel generators inoperable, the plant entered Technical Specification 3.8.1, a 2-hour shutdown Action Statement.
"Division 1 and 2 diesel room exhaust fans stopped rotating, and the outside air temperature lowered to less than 72°F The Technical Specification Action Statements were exited. Periodic monitoring of the fans has been established to address reoccurrence of the condition."
The NRC resident inspector has been informed of this event by the licensee.
* * * RETRACTED AT 1400 EDT ON 4/18/01 BY THOMAS RESTUCCIO TO FANGIE JONES * * *
The licensee is retracting the event notification based on the following:
"Event notification 37900 was written due to the inoperability of Division I and II emergency diesel generators. The diesel generators were declared inoperable due to the diesel generator room exhaust fans spinning backwards. The issue was that under reverse rotation, starting currents may exceed trip values rendering the exhaust fans inoperable and, as a result, causing the diesel generators to be declared inoperable.
"At the time of discovery it was identified that the diesel generator exhaust fans for Division I and II were observed to be rotating backwards at approximately 10-15 rpms. An engineering analysis performed by the licensee has determined that the tans can be spinning backwards up to 235 rpm and will start and operate normally if needed. There will be no adverse affect on the fans operability to perform their design safety function."
The licensee notified the NRC Resident Inspector. The R1DO (William Ruland) was notified.
