SHUTTER AND SHUTTER MECHANISM SEPARATED FROM SOURCE HOLDER

"On December 20, 2016 [at approximately] 1510 CST, a [level detector] nuclear source holder was found fallen off of its mounting on the unit 2 economizer hopper #49. The shutter mechanism and the shutter appear to have separated from the source holder. This occurred at the Indiana Michigan Power Rockport plant in Rockport, Indiana. The source holder is a Vega Americas Model SHLD-1-45, serial number: 7185CP. It is a 20 millicurie Cesium 137 source. The plant's general license number is GL704402-21. The radiation around the fallen source holder was tested and found to be a maximum of 35 millirem/hr at 1 foot in the source beam path. The radiation was tested at the 20 foot boundary where danger tape has been placed around the source holder and readings of 0.08 to 0.12 millirem/hr were noted. A nuclear technician from Vega Americas is currently on his way to the plant and we are planning to attempt to repair the source holder this evening [December 21].

"If we are unable to repair the source holder it will be prepared for shipping and will be sent back to Vega Americas' office in Cincinnati, Ohio for repair."

TROXLER MOISTURE DENSITY GAUGE DAMAGED

A Troxler moisture density gauge (Model 3440) was damaged when it was struck by an asphalt roller. The source rod was out at the time of the incident but the source was able to be retracted into the shielded position.

The licensee's radiation safety officer surveyed the meter and found no abnormal radiation readings. The gauge was transported back to the licensee's facility for storage awaiting results of the swipe test. Once the swipe test results are returned, the licensee intends to ship the gauge to the vendor for repair or replacement.

The gauge contains Am-241/Be and Cs-137 sources. No personnel overexposures occurred during this incident.

AGREEMENT STATE REPORT - MEDICAL UNDERDOSE

The following report was received via fax:

"On December 20, 2016, a leak occurred during an administration of Yttrium-90 (Y-90) TheraSpheres to a patient, resulting in less than 80% of the prescribed dosage being administered. A total of about 8.99 millicurie of Y-90 activity was administered; or 34.6% of the prescribed 25.95 mCi activity. The prescribed dose was 17,470 rad (174.7 gray), with the leak resulting in a dose to the patient's liver of about 6,040 rad (60.4 Gy). The leak also caused contamination of the administration area, which was immediately and successfully decontaminated. As an under-dose, no immediate harmful effect to the patient resulted from the event. The referring physician and patient were made aware of the event during the procedure."

Pennsylvania event: PA-160040

A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.

LOSS OF TECHNICAL SUPPPORT CENTER VENTILATION SYSTEM

"Oyster Creek Generating Station has experienced a loss of the TSC [Technical Support Center] ventilation system.

"If an emergency is declared requiring TSC activation during the time TSC ventilation is non-functional, the TSC will be staffed and activated using existing emergency planning procedure unless the TSC becomes uninhabitable due to ambient temperature, radiological, or other conditions. If relocation of the TSC becomes necessary, the Emergency Director will relocate the TSC staff to an alternate location in accordance with applicable site procedures.

"This notification is being made in accordance with 10 CFR 50.72(b)(3)(xiii) due to a potential loss of the TSC. An update will be provided once the TSC ventilation has been restored to normal operation.

"The NRC Resident Inspector has been notified."

PART 21 - ISSUES IDENTIFIED WITH THE ENTERPRISE DIESEL ENGINE SUBCOVER

The following information is excerpted from a facsimile report submitted:

"Engine Systems Inc. (ESI) began a 10 CFR 21 evaluation on November 18, 2016 upon notification of an issue with a subcover assembly at Perry Nuclear Plant. Attempts to install the subcover on their Enterprise diesel engine revealed two issues that prevented successful installation. First, one of the bolt holes was not fully machined through the entire depth of the subcover. Though the bolt could be inserted into the top of its corresponding hole, it would not pass completely through. The second issue was an interference between the rocker arm shaft and its mating pedestal. It was found that incomplete machining of the pedestal prevented the shaft from sitting flat on the pedestal.

"The evaluation was concluded on 12/21/16 and it was determined that this issue is a reportable defect as defined by 10 CFR 21."

The affected facilities are:
First Energy - Perry
Georgia Power - Vogtle

Also listed was the following affected facility:
Korea - Yonggwang

Component: Subcover Assembly, P/N 1A-7846
