EN Revision Text: AGREEMENT STATE REPORT - LEAKING SEALED SOURCE

The following was received from the Maine Radiation Control Program via fax:

"At 0857 [EST on November 15, 2019,] NETCo, Inc. notified the state of Maine Radiation Control Progam [the State] that they had received leak test results from their vendor [Radiation Safety & Control Services] RSCS. One the test results indicated the Ni-63 source in a replacement component to a SAFRAN Morpho Detection Trace device was leaking. Two additional tests on components with Ni-63 sources reported detectable activity but less than 0.0005 microCi. The source contains 10.0 mCi of Ni-63 and the leak test result was 0.1968 microCi on the leaking source.

"The RSO at NETCo has surveyed the work area where the leak tests were performed along with the storage container and bag that they arrived in. No detectable activity was found. NETCo will be also performing smear tests of all the areas that came in contact with the sources. The sources (components) in question will be put in a one gallon paint can awaiting proper disposal in our locked cabinet.

"The State has sent an inspector to perform additional surveys. Licensee will be providing a full report to the State as information becomes available."

* * * UPDATE ON 12/17/19 AT 1415 FROM TOM HILLMAN TO OSSY FONT * * *

The following was received from the State via email:

"The licensee and the State performed surveys and wipe samples. All surveys results were not above background. Wipe samples were all below 0.005 microCi. The wipe on the leaking source was slightly elevated but below the 0.005 microCi. The license notified the shipper of the sources, a radiation officer at Beaver Valley Power Plant. The sources were shipped for disposal and plans for disposal will continue."

The state has closed the event.

AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGN

This is a summary of information received from the state of Nebraska via a phone call:

On November 20, 2019, the state of Nebraska identified a lost tritium exit sign during their quarterly reports. The general licensee indicated that they improperly disposed of the exit sign by donating it to a second-hand store on May 15, 2019. The exit sign has not been located at this time. The second-hand store turns over their inventory every six months, so it is believed that the exit sign has been sold or disposed of.

The tritium exit sign is a Betalux model BX-20-BK (S/N: C167432) with an activity of 17.51 Ci.

No further investigation is planned at this time and Nebraska has closed the event.

Nebraska incident number: NE190005

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.

AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGN

This is a summary of information received from the state of Nebraska via a phone call:

On December 2, 2019, the state of Nebraska identified a lost tritium exit sign that was improperly transferred by the licensee to the state of Wisconsin. The general licensee indicated that they transferred the exit sign to a electronics company in Wisconsin, which was not licensed to possess radioactive materials. It is believed that the sign was reused by the electric company. The company was contacted and is working with the Wisconsin Department of Health on ascertaining the exit sign's location.

The tritium exit sign is a Isolite model 2000 (S/N: H114041) with an activity of 12.57 Ci.

No further investigation is planned at this time and Nebraska has closed the event.

Nebraska incident number: NE190006

AGREEMENT STATE REPORT - LOST LICENSED NUCLEAR MATERIAL

This is a summary of information received from the state of Nebraska via a phone call:

On November 12, 2019, the licensee packaged low level waste into 55-gallon barrels to be shipped to a disposal facility. On December 3, 2019, the disposal facility arrived to pick up the waste and discovered that one of the barrels was missing. The missing barrel contained 11 mCi of C-14. It is believed that the waste was improperly disposed of in another waste stream.

The investigation is ongoing at this time and the event is open with the state of Nebraska.

TECHNICAL SPECIFICATION REQUIRED SHUTDOWN

At 1929 EST, on 12/17/19, Millstone Unit 3 began preparations for shutting down the reactor as the 'A' Emergency Diesel Generator (EDG) could not be restored to operable status within the 14-day outage time, requiring a Technical Specification (Tech Spec) shutdown.

Per Tech Spec 3.8.1.1., the reactor must be in Hot Standby in six (6) hours, and Cold Shutdown within the following 30 hours. Hot Standby is estimated by midnight, and Cold Shutdown by 1800 EST on 12/18/19.

All other safety and shutdown systems are operable. Decay heat removal will be through the Shut Down Cooling and Residual Heat Removal systems.

There was no impact to Unit 2. There was no impact to the health and safety of the public or plant personnel.

The licensee notified the state of Connecticut, Waterford County, and the NRC Resident Inspector.
