| Event Text AGREEMENT STATE REPORT - MOISTURE DENSITY GAUGE DAMAGED
The following information was received from the California Radiologic Health Branch via e-mail:
"On February 6, 2013, the licensee notified the California Department of Public Health that one of their moisture density gauges (CPN MC-1DRP, 10 mCi Cs-137, 50 mCi Am:Be-241, S/N MD00605734) was struck by a small bobcat tractor at a construction site at approximately 2:00 P.M. The gauge user had placed the gauge on the ground by the back bumper as he went to retrieve something from the cab of this truck. He no sooner started walking from the back of the truck to the side of the truck when the bobcat ran over the gauge.
"The RSO reported that although the gauge's guide tube was broken off, the body of the gauge itself was not damaged and the Cs-137 and Am-241:Be sources remained fully shielded. The external shutter, however, was slightly open. The gauge was returned to the transport case and was transported back to the licensee's facility. The RSO then contacted the manufacturer, InstroTek who instructed the RSO on how to close the shutter safely. There was no additional exposure through the external shutter even though it was slightly open because the internal shutter had remained closed during the entire event as the source rod was in the 'safe' position.
"The gauge user was wearing a whole body dosimeter which was immediately sent in for immediate processing. On February 7, 2013, [representatives from] the California Department of Public Health met with the licensee. All survey measurements were as expected for this type of gauge and there was no removable contamination found. An additional piece of lead was taped to the external shutter as a precaution during transit. The dose to any individual from this incident is estimated to be less than 0.5 millirem. The gauge is being shipped to InstroTek later today for repair."

The following report was received from the Commonwealth of Massachusetts Radiation Control Program via facsimile:
"On 1/28/13, the radiation monitors at `Schnitzer Steel', a scrap metal dealer, detected radiation coming from an incoming truck loaded with scrap metal for disposal. The measured radiation level was 5.3 uR/hr with a background of 3.1 uR/hr. The load was rejected. The MA Radiation Control Program issued a 'DOT-SP 10656 shipment approval form' in order for the truck to return to 'Testa Corporation' [originator of the scrap shipment] of Maynard, MA. At the Maynard site, a consultant unloaded the scrap onto the ground and discovered 21 old smoke detectors. The smoke detector label identified the manufacturer as `Kiddie Corporation, Ashland, MA' and stated the smoke detector contained 1 uCi of Ra-226. The consultant secured all of the smoke detectors from unauthorized removal and is arranging for disposal via a licensed radioactive materials (RAM) waste broker."

The following report was received from State of Texas Radiation Branch via e-mail:
"On February 7, 2013, the Agency [State of Texas Radiation Branch] was notified by the licensee that the shutter on an Ohmart model SH-F1A nuclear gauge was stuck in the open position. The gauge contains a 50 millicurie cesium - 137 source. Open is the normal operating position for this gauge. The licensee has notified their personnel that no entry into the vessel the gauge is mounted on is allowed until the gauge is repaired. The manufacturer has been contacted and arrangements to repair the gauge are being completed. The failure does not create an exposure risk to any individual. This gauge had previously failed in February of 2012 (EN47691). Additional information will be provided as it is received in accordance with SA - 300."

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text MISSING NICKEL-63 SOURCE USED FOR ELECTRON CAPTURE DETECTOR
The licensee called to report a missing 15 millicurie Nickel-63 source (serial #5404) used in a gas chromatograph electron capture detector. The licensee is in the process of moving their business location and discovered that this specific source was missing. It was last inventoried 29 days ago. All other sources possessed by the licensee have been accounted for. The licensee is still searching for the source which may have been misplaced in the move. However, there is a possibility that the source may have been inadvertently disposed.
The licensee has notified NRC Region 1 (Jackson).
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.

"At 2030 hours [EST] on February 14, 2013, technical specification (TS) 3.7.7 condition A was entered due to the right train of the component cooling water (CCW) system being declared inoperable. The cause of the inoperable train was the identification of an approximate 40 gallon per hour CCW system to service water system leak inside the 'A' CCW heat exchanger. TS 3.7.7 condition A requires restoration of the inoperable train within 72 hours. If the restoration is not completed within 72 hours, the plant must be in Mode 3 within 6 hours and in Mode 5 within the subsequent 36 hours.
"Due to the inability to repair the leak within the required 72 hour time frame during power operation, a plant shutdown was initiated at approximately 1300 hours on February 15, 2013. Entry into Mode 3 is expected at approximately 1700 hours on February 15, 2013. The plant will enter Mode 5 to execute leak repair. Mode 5 entry is expected at approximately 0800 hours on February 16, 2013.

Plant Technicians were performing a Technical Specification (TS) Surveillance, 'Average Power Range Monitor Flow Biased/Neutron Flux Response Time Test,' when a test cable connector contacted a fuse block staple jumper, causing the transfer of the Division 4 NSPS bus from normal inverter source to its alternate source.
"TS 3.8.7, 'Inverters - Operating' Surveillance Requirement 3.8.7.1 is not met with the inverter on the alternate source, and Condition C, requires High Pressure Core Spray (HPCS) system to be declared inoperable immediately since the Division 4 NSPS bus was not energized from the inverter. Since HPCS is an emergency core cooling system and is a single train safety system, this is a condition that could have prevented fulfillment of a safety function and is reportable under 10 CFR 50.72(b)(3)(v)(D), system needed to mitigate the consequences of an accident.
"At 0925 CST, the Division 4 NSPS bus has been restored to service on the normal source. At 0925 CST, HPCS has been declared Operable.
"The NRC Resident has been notified." |

"On February 18, 2013 at 0515 hours, with the reactor at 100% core thermal power, a scram discharge volume valve, CV-302-22B was declared inoperable as required by station procedural direction due to an observed degradation in opening stroke time during performance of quarterly surveillance testing of the Scram Discharge Instrument Volume Vent and Drain Valves. This action was taken consistent with NRC IE Bulletin 80-14.
"Currently, station engineering is evaluating the valve stroke time trend data of CV-302-22B and a plan to address this issue will be developed as part of the Corrective Action Program. Pilgrim Technical Specification 3.3.G applies due to the inoperability of CV-302-22B.
"This notification is being made in accordance with NRC IE Bulletin 80-14, 'Degradation of BWR Scram Discharge Volume Capability,' Part A.3, which states, 'By procedures, require that the SDV [scram discharge volume] vent and drain valves be normally operable, open and periodically tested. If these valves are not operable or are closed for more than 1 hour in any 24 hour period during operation, the reason shall be logged and the NRC notified within 24 hours (Prompt Notification).
"This event has no impact on the health and safety of the public.
"The NRC Senior Resident Inspector has been informed."
