INADVERTENT EDG START

"On 12/7/08 at 2010 CST, Emergency Diesel Generator 2 was started manually from its local control cabinet. The diesel started and operated as designed upon operation of the local Emergency Start Push button. This was an inadvertent start of the diesel during an alarm test on the local engine panel. The alarm test and emergency start push buttons are in close proximity and of similar design and color. The diesel has since been shutdown and returned to a standby condition. The Emergency Diesel Generator remains capable of performing its designed function and was considered operable throughout the evolution. Therefore this report is being made in reference to 10CFR 50.72(b)(3)(iv)(A) .

"The licensee notified the NRC Resident Inspector."

* * * RETRACTION AT 1549 EST ON 12/10/2008 FROM ERICK MATZKE TO MARK ABRAMOVITZ * * *

"On 12/7/2008, Fort Calhoun reported an inadvertent start of a diesel generator (event Number 44703). Based on a detailed review of NUREG-1022, this event has been determined not to be reportable under 10 CFR 50.72(b)(3)(iv)(A) . As reported, the diesel generator was not intentionally manually started by the operator. Therefore, this event was an invalid actuation of the safety system and this notification is being retracted. An appropriate report will be forthcoming as required by 10CFR50.73(a)(2)(iv)(A) and 10CFR50.73(a)(1)."

The licensee notified the NRC Resident Inspector.

Notified the R4DO (Cain).

AGREEMENT STATE - TEXAS - REPORT OF MISSING GAUGE CONTAINING 2 CURIE CESIUM-137 SOURCE

The following was received from the Texas Department of State Health via e-mail:

"The gauge was discovered missing after Agency attempts to collect fees. Gauge registrant had provided self evaluation reports indicating they possessed the gauge and, after being contacted, admitted it was missing. The company had 2 gauges. The second was returned to Thermo Scientific.

"The missing gauge is reported to contain 1 curie of Cs-137. However, the manufacturer's information indicates it held 2 curies. A site investigation will be performed 12/09/08. The source information follows: Manufacturer: Thermo MeasureTech (Now Thermo Fisher Scientific), Model: 5203, Serial Number: B996, Isotope: Cs-137, Activity: 2 Ci, Source serial number: GK3804."

The State of Texas is reporting this as their equivalent to NRC regulation 20.2201(a)(1)(i); reports of theft or loss of licensed materials > 1000 X App. C value.

A representative of the State of Texas (Robert Free) was contacted and it was determined that the date that the gauge went missing or the circumstances are unknown at this time. The licensee is a dredging company that used the density gauge for underwater dredging activities associated with installing underwater pipelines.

Texas report I-8587

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

INVALID ACTUATION OF AN EMERGENCY DIESEL GENERATOR

"This notification of a system actuation is provided in accordance with 10 CFR 50.73(a)(2)(iv)(A). The Licensee is providing a telephone notification to the NRC Operations Center in accordance with 10 CFR 50.73(a)(1) instead of submitting a written Licensee Event Report, as the system actuation was invalid and was not the result of an actuation of the reactor protection system when the reactor was critical. The event involved the invalid actuation of 'Emergency AC electrical power systems, including: emergency diesel generators' as discussed in 10 CFR 50.73(a)(2)(iv)(B).

"At 1827 on November 16, 2008, with Calvert Cliffs Unit 2 operating at approximately 100% power, the Train A (2A) Emergency Diesel Generator (EDG) automatically started from the standby condition. The automatic start was caused by a degraded switch in the start circuit for the EDG. The 2A EDG successfully started and functioned properly, but did not automatically connect to the associated bus ('21' 4KV Bus) because no bus undervoltage signal was present. The 2A EDG start is considered to be invalid, as the start signal was not generated in response to actual plant conditions or parameters satisfying the requirements for initiation of the EDG start. The start was also not the result of an intentional manual action.

"The 2A EDG was removed from service and the Station Blackout diesel generator was aligned to '21' 4KV Bus.

"Following replacement of the degraded switch, the 2A EDG was tested and returned to Service at 2030 on November 17, 2008.

"The 2B EDG remained operable during this event.

"The licensee notified the NRC Resident Inspector."

The degraded switch was in the EDG room and had degraded resulting in high resistance i.e. simulated an open circuit, which started the diesel.

OFFSITE NOTIFICATION MADE DUE TO MINOR OIL SPILL

"On December 10, 2008 at approximately 8:30 the control room was notified of an oil sheen in the discharge canal. An Operator was dispatched to assess the condition and its significance. At Approximately 1037 hours the CCR [Central Control Room] was informed that an apparent oil sheen had been observed in the Hudson River. The oil is partially contained by a boom in the outfall structure and the amount of oil released to the river is estimated to be less than one gallon. A sample of the material has been collected to determine what type of substance it is. The source of the apparent sheen is unknown and remains under investigation. In accordance with the Indian Point Spill/Release plan a spill or leak from Indian Point causing a visible sheen in the river as a result of a release of a petroleum product requires notification of the New York State Department of Environmental Conservation and the Coast Guard National Response Center. An environmental cleanup vendor has been contacted for assessment and cleanup.

"The NRC resident has been informed."
