AGREEMENT STATE REPORT - TWO LOST Po-210 IONIZERS

The following was received from the New York State Department of Health (NYSDOH) via fax:

"On October 22, 2019, the Department [New York State Department of Health] was notified by e-mail of two lost static elimination devices, NRD, LLC Model P-2042 1000 'Nuclespot Ionizer', S/N A2LL994 and A2LC660. The devices has a maximum activity of 5 millicuries of Polonium-210 at the time of manufacture. Based on the information provided to the Department, the activity of the device on October 21, 2019 (date of discovery) would be approximately 0.8 and 0.14 millicuries, respectfully.

"The licensee [Buffalo Pharmacies] indicated that the devices had not been used in quite some time and that the facility at which the devices were used had recently closed. Between the lack of use and the closing of the facility, the devices has been deemed lost."

EVENT REPORT ID NO.: NYDOH-19-10

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.

MANUAL TRIP DUE TO FEEDWATER PUMP TRIP

This is a synopsis of initial information received via phone:

On December 27, 2019, at 0705 EST, while Unit 2 was at 100 percent (Mode 1), the 'A' Main Feedwater Pump tripped due to an unknown cause. The reactor was manually tripped and is currently at zero (0) percent power (Mode 3). Decay heat is being removed via Auxiliary Feedwater. The 'B' Feedwater pump is operable.

There was no impact on Unit 3.

The licensee notified the NRC Resident Inspector. Additionally, Connecticut Department of Environmental Protection, Waterford Dispatch, and East Lyme Emergency Management Division will be notified.

* * * UPDATE ON 12/27/2019 AT 1330 EST FROM JASON PARIS TO CATY NOLAN * * *

"This is an update to NRC Event Number 54457.

"At 0704 EST, on 12/27/2019, with Millstone Unit 2 operating at 100 percent power, operators inserted a manual reactor trip. The trip was initiated due to a trip of the 'A' Main Feedwater Pump.

"The Auxiliary Feedwater System (AFW) automatically actuated as required.

"All control and shutdown rods fully inserted. All safety systems responded as designed. No primary or secondary safety valves actuated during or after the transient. Unit 2 is currently stable at normal operating pressure and temperature in Mode 3, Hot Standby. Reactor Coolant System (RCS) temperature is being maintained by the steam dump system with all Reactor Coolant Pumps (RCPs) in service. Main Feedwater has been secured, and Auxiliary Feedwater is in service. The electrical system is in normal alignment.

"There was no impact on Unit 3. There was no impact to the health and safety of the public or plant personnel.

"Due to Reactor Protection System (RPS) actuation while critical, this event was reported as a four hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B); and an eight hour non-emergency notification in accordance with 10 CFR 50.72(b)(3)(iv)(A) as an event that resulted in a valid actuation of the AFW system."

The licensee will notify the NRC Resident Inspector of the update.

Notified R1DO (Cherubini).
