OFFSITE NOTIFICATION REGARDING APPROVAL TO EXCEED THE NORMAL OPERATING DISCHARGE TEMPERATURE PERMIT LIMIT DUE TO THE EMERGENCY NEED FOR POWER AND CONDITIONS ON THE GRID
At approximately 1500, the licensee began to reduce reactor power from 100% because main condenser discharge temperature began to approach the discharge permit temperature limit of 106°F. At 1601, the system dispatcher notified the licensee of an emergency need for power and informed the licensee that the criteria to exceed the discharge permit temperature limit was authorized. In this condition, a discharge temperature of 110°F is allowed. As a result, the licensee ceased the power reduction with the unit at approximately 98% reactor power and returned reactor power to 100%.
The emergency need for power was cancelled at 1612. As a result, the licensee commenced another power reduction in order to reduce the main condenser discharge temperature and comply with the 106°F discharge permit limit.
The highest main condenser discharge temperature attained was 106.36°F. Reactor power is currently stable at 93%.
The licensee notified the New Jersey Department of Environmental Protection and plans to notify the NRC resident inspector.

DISCOVERY THAT SUPPORTS MAY NOT BE CAPABLE OF PROPERLY RESTRAINING THE MISSILE SHIELD DURING A DESIGN BASIS SEISMIC EVENT
The following text is a portion of a facsimile received from the licensee:
"Evaluation of the Missile Shield, over the Reactor Vessel Head, has revealed that the supports for the Missile Shield may not be capable of properly restraining the Missile [Shield] in the horizontal direction during a Design Basis Seismic Event. Consequently the Missile Shield is considered inoperable pending further evaluation. This is being reported as an unanalyzed condition that could significantly degrade Plant safety."
The licensee notified the NRC resident inspector.
* * * RETRACTED AT 1602 EST ON 11/19/01 BY DAN MALONE TO FANGIE JONES * * *
The licensee is retracting this event after further evaluation determined that the supports for the Missile Shield are adequate to restrain it during a Design Basis Seismic Event. The shield has been determined to be Operable, but degraded.
The licensee notified the NRC Resident Inspector. The R3DO (Christine Lipa) has been notified.

STOLEN HUMBOLDT 5001C NUCLEAR GAUGE
The gauge was lost during the hours of darkness July 15-16, 2001, from the back of a truck that was parked overnight at the home of the driver. The gauge and it's transport case were removed from a parked pickup truck by cutting the chain securing the gauge to the bed of the truck. Also stolen during this incident was the operator's toolbox and assorted hand tools. The gauge is a Humboldt Model 5001C, Serial # 2606, containing two radioactive sources: 10 millicuries of cesium-137, Serial #6171GQ; and 40 millicuries of americium-241;Be, Serial # NJ02767. A police report was filed on July 16, 2001, with the Dallas Police Department (Report # 0551265-K). A press release offering a $250 reward for the return of the gauge was run in the Dallas Morning News for two days. The gauge has not been recovered as of this date. The licensee has been cited for failure to maintain the gauge under constant surveillance. The state of Texas has informed the Radiation Control authorities in Mexico, Arizona, New Mexico, Arkansas, and Louisiana, as well as the Humboldt Radiation Safety Officer.
