Event Notification Report for July 11, 2014

AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE

The following was received from the Commonwealth of Kentucky via email:

"KY RHB [Kentucky Radiation Health Branch] was notified by telephone on 7/11/14 by Todd Ramkey, Corporate RSO at Schnabel Engineering Inc. in Glenn Allen, VA, of the fact that a CPN model MC-1 portable moisture/density gauge had been run over and crushed at a coal slurry impoundment belonging to Long Fork Coal Company in Hatfield, KY. The CPN gauge contained 10 mCi of Cs-137 and 50 mCi of Am-241/Be.

"Initial surveys performed by the licensee with a RadAlert GM survey instrument indicated the sources were not breached and that there was no contamination on the ground where the incident occurred or on the bulldozer involved. The shattered pieces of the device, including the two sources, were packaged on-site by the licensee into a 55 gallon drum in accordance with guidance provided by the radiation safety staff at Instro-Tek in Raleigh, NC, labeled appropriately and shipped back to the offices of Geo/Environmental Associates, Inc. in Knoxville, TN in a company owned vehicle. The shipment was met by a representative of the TN Division of Radiological Health where follow-on surveys and contamination smears were taken. They also instructed the licensee to send leak test wipes to Instro-Tek for expedited analysis and instructed the licensee to send personal monitoring for those involved in for analysis.

"A telephone call to RHB from the CRSO at Schnabel on 7/14/14 at approximately 1500 said indicated leak test results from Instro-Tek were less than the 185 Bq limit and that no breach of the sources had occurred. RHB gave the CRSO permission to release the control of the site and the equipment at Long Fork Coal based on these negative leak test results. The CRSO at Schnabel indicated that hardcopies of the leak test results would be provided to both RHB and TN Div. Rad Health as well as the results of personal monitoring for those involved in the incident including transportation of the gauge back to Knoxville. Reporting criteria defined in 902 KAR 100:040, Section 15(2)(b) [10 CFR 30.50(b)(2)]."

MANUAL SCRAM DUE TO LOSS OF MAIN CONDENSER VACUUM

"Today at approximately 0312 [EDT on 7/11/14], during a planned reactor power ascension with reactor power at approximately 55 percent of rated thermal power, main condenser vacuum began to lower. In accordance with the abnormal operating procedure for degrading vacuum, Operators inserted a manual scram of the reactor at 0314 [EDT]. The cause of the degraded vacuum is currently under investigation.

"All rods inserted into the core and all systems functioned as expected during the scram. No electromatic (EMRVs) or safety relief valves lifted during the transient.

"This event is reportable within 4 hours per 10CFR50.72(b)(2)(iv)(B) - any event or condition that results in actuation of the reactor protection system (RPS) when the reactor is critical except when the actuation results from and is part of a pre-planned sequence during testing or reactor operation."

The scram was uncomplicated, normal offsite power is available, and plant is being cooled down to cold shutdown. The cause of the degraded condenser vacuum is suspected condenser boot degradation.

The licensee has informed the NRC Resident Inspector.

AGREEMENT STATE REPORT - FIXED GAUGE SHUTTER STUCK IN CLOSED POSITION

The following information was received via e-mail:

"The licensee reported the malfunction of the shutter mechanism on a fixed gauge. The device is stuck in the closed position. Repair to the shutter will be made by the manufacturer, Ohmart-Vega. A date for their site visit to repair the shutter is pending. Information about the source is shown below:
Manufacturer: Ohmart/Vega
Model: SH-F2
Serial #: 13549338
Source Serial #: 1224CO
Isotope: Cs-137
Initial Activity: 500mCi"

Ohio Report Number: OH 2014-019

LOSS OF ASSESSMENT CAPABILITY - LOSS OF POWER TO THE PLANT PROCESS COMPUTER

"At 0823 EDT on Friday, July 11, 2014, the Pilgrim Nuclear Power Station (PNPS) determined that the plant process computer and, therefore, the in-plant Safety Parameter Display System (SPDS) was not functioning as designed due to a loss of power. The SPDS provides numerous plant parameters, some of which are credited for emergency assessment capability. The site has determined that this constitutes a major loss of assessment capability. Immediate actions were taken to restore the system to functional status and applicable plant procedures were entered to determine temporary mitigating actions. Power was subsequently restored at approximately 1030 EDT via an alternate supply, and SPDS has been restored to normal operation.

"This event had no impact on the health and/or safety of the public.

"This notification is conservatively being made in accordance with 10 CFR 50.72 (b)(3)(xiii).

"There is no impact to plant operations."

The licensee notified the NRC Resident Inspector and will notify the State.

AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE

"Tennessee Div. of Radiological Health was notified on 7/11/14, by a representative form Geo/Environmental Associates, that a CPN Model MCI, portable moisture density gauge containing 10 mCi, Cs-137 and 50 mCi, Am-241 was run over by a bulldozer at a construction site in Kentucky while working under reciprocity in that state. Initial surveys performed on the device indicate the source was not damaged and there was no loss of sources from the device. The device is being returned to it's home storage site in Knoxville, Tennessee and will be assessed by state inspectors with further investigation."

The gauge was surveyed and is showing 40 mR/hr on contact.

Tennessee Report Number: TN-14-138

* * * RETRACTION PROVIDED BY BILLY FREEMAN TO JEFF ROTTON VIA EMAIL AT 0913 EDT ON 07/14/2014 * * *

The State of Tennessee is retracting this event due to the fact that this event notification should be made by the Commonwealth of Kentucky where the event occurred.

Notified R1DO (Cahill) and FSME Events Resource via email.

OFFSITE NOTIFICATION MADE FOR HAZARDOUS CHEMICAL SPILL

"At 1415 [EDT] the Control Room received a report that a refrigeration unit had failed and was spilling coolant (Ethylene Glycol) on the floor of an office building inside the protected area. At 1440 [EDT] the leak was isolated. It is estimated that approximately 10 gallons of Ethylene Glycol was introduced to the floor drains which ultimately lead to the environment. This is not a Reportable Quantity for the Environmental Protection Agency but the Pennsylvania Department of Environmental Protection was notified in accordance with the Pennsylvania Clean Streams Law at 1500 hours. The spill was contained and cleanup is complete.

"This condition is being reported pursuant to 10 CFR 50.72 (b)(2)(xi).

"The NRC Resident Inspector has been notified."
