Event Notification Report for October 16, 2014

MOMENTARY LOSS OF SECONDARY CONTAINMENT

"Nine Mile Point Unit 1 (NMP1) had a momentary loss of Secondary Containment due to both Reactor Building airlock doors being opened at the same time.

"At 1042 EDT on 10/16/2014, both Reactor Building airlock doors at NMP1 were opened simultaneously for less than 5 seconds. This results in a momentary loss of Secondary Containment operability (TS 3.4.3). The doors were closed and operability was restored.

"Secondary Containment being inoperable is an 8 hour notification per 10 CFR 50.72(b)(3)(v)(C), 'any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to control the release of radioactive material.'

"The condition has been entered into the station's corrective action program and the NRC Senior Resident Inspector was notified."

The licensee will be notifying the State of New York Public Service Commission.

PALLADIUM-103 BRACHYTHERAPY SEED BROKEN

"A Palladium-103 (Pd-103) brachytherapy seed (Theragenics Model 200 nominal activity 1.5 mCi) broke when the Mick shielded magazine was removed from the applicator. An activity of [approximately] 0.5 mCi for the lost portion of the seed was calculated by measuring the remaining portion of the seed. It was not recovered and presumed to have washed down a sink drain. The seed was broken and lost October 15, 2014 around 0945 [EDT]. The incident was discovered around 1645. Surveys of the area for the lost portion returned no radiation above background. Contamination from the seed is remote because the Pd-103 is coated on (adhered to) a graphite pellet. No personnel radiation exposure data available. It is unlikely the person involved received measurable dose.

"The process for removing the cartridge at the end of a procedure will be reviewed to reduce the chance of this happening again."

The licensee contacted NRC Region 3 DNMS personnel.

AGREEMENT STATE REPORT - LOST TROXLER MOISTURE DENSITY GAUGE

The following information was provided by the State of Utah via email:

"Event Description: The licensee failed to properly secure a moisture density gauge in a locked transportation case before leaving a temporary jobsite in a pickup truck. The device fell out of the truck onto the road. The licensee has not been able to locate the device. The local law enforcement agency has been notified."

The event location was 900 East and 5200 South, Murray, Utah. The device is a Troxler Model 3440, Serial number - 69079. This device contains 8 mCi of Cs-137 and 40 mCi of Am-241.

UT Event Report ID No.: UT140004

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.

PART 21 - INSUFFICIENT SPOT WELD ON WIRE WOUND RESISTOR

The following information was excerpted from a facsimile from AMETEK Solidstate Controls:

Ohmite 5 watt, 470 ohm wire wound resistor with component Date Code 1201 is mounted on a printed circuit board installed in power supplies manufactured by Ametek Solidstate Controls.

"Component Description: Ohmite 5 watt, 470 ohm wire wound resistor with Date Code 1201

"Problem You Could See: Internal open - (100 hour burn-in performed)

"Probable Cause: Insufficient spot weld on the wire wound resistor

"Effect on System Performance: Resistor opens

"Action Required: Notify NRC and affected utilities. Prepare replacements.

"Ametek Solidstate Controls Corrective Action Taken: Notified affected utilities of the potential defect and advised that the power supplies be returned to our factory. Further corrective action will be to install new boards with unaffected resistors, retest, perform 100 hour burn in and return."

Person notifying the NRC: Mr. Robert George, Director of Quality, 875 Dearborn Drive, Columbus, OH 43085, Telephone: (614) 846-7500
