EN Revision Text: MANUAL REACTOR TRIP

The following information was provided by the licensee via fax or email:

"At 2207 [EST] on 2/21/2022 with Unit 2 in Mode 1 at 68 percent power, the reactor was manually tripped due to lowering water level in the 2A Steam Generator. The trip was not complex with all systems responding normally post-trip.

"Operators responded and stabilized the plant. Decay heat is being removed by discharging steam to the main condenser using the turbine bypass valves. Units 1 and 3 were not affected.

"Due to the Reactor Protection System actuation while critical, this event is being reported as a four-hour, non- emergency notification per 10 CFR 50.72(b)(2)(iv)(B).

"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

* * * UPDATE ON 3/23/22 AT 1643 EDT FROM CHRIS MCDUFFIE TO TOM KENDZIA * * *

The following information was provided by the licensee via phone and email:

"On 2/21/2022, Unit 2 was in Mode 1 increasing reactor power following startup from a forced outage. At 2205 [EST] with Unit 2 at 68 percent power, a feedwater control valve failed to properly control feedwater flow to the 2A Steam Generator and the Integrated Control System initiated an automatic runback. At 2207 [EST], the reactor was manually tripped from 39 percent power due to lowering water level in the 2A Steam Generator. Immediately following the manual reactor trip, an actuation of the Emergency Feedwater System (EFW) occurred. The 2A and 2B Motor Driven Emergency Feedwater (MDEFW) pumps automatically started as designed when the 'low steam generator level' signal was received for the 2A Steam Generator. The trip was not complex with all systems responding normally post-trip. Operators responded and stabilized the plant. Decay heat was removed by discharging steam to the main condenser using the turbine bypass valves. Units 1 and 3 were not affected. Unit 2 was restarted on 2/27/2022 following repairs.

"Due to the Reactor Protection System actuation while critical, this event was reported on 2/22/2022 as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B). Following further evaluation, it was determined that a valid EFW actuation occurred, therefore this event is now also being reported as a late 8-hour non-emergency notification of a valid actuation of the EFW system in accordance with 10 CFR 50.72(b)(3)(iv)(A).

"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

EN Revision Text: AGREEMENT STATE REPORT- LOSS/MISDELIVERY OF NUCLEAR DENSITY GAUGE

The following information was provided by the Pennsylvania Department Bureau of Radiation Protection (Department) via email:

"On March 16, 2022, the licensee informed the Department of an event that is reportable per 10 CFR 20.2201(a)(1)(i).

"The Department received notification from a licensee on March 16, 2022, that a Troxler 3440 portable gauge (serial number 62679) was delivered to the wrong location and to the wrong licensee. The gauge contains 9 mCi of Cs-137 and 44 mCi of Am-241:Be. The gauge was incorrectly delivered to KU Resources, another Pennsylvania licensee (PA-1247), by [the common carrier]. The device was on its way back from being serviced by commercial vendor, lnstroTek (PA-1522). KU Resources also had gauge(s) at lnstroTek for service. KU Resources has secured the device in its vault while the carrier and service provider arrange proper delivery back to the proper licensee.

"The cause of the event is unknown at this time. The Department will perform a reactive inspection as soon as possible."

Pennsylvania Event Number: PA220011

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.

EN Revision Text: AGREEMENT STATE REPORT - FOUND AM-241 SOURCE

The following information was received via E-mail from the Arkansas Department of Health (ADH):

"WW Recycling in Marmaduke, Arkansas, reported to Arkansas Radiation Control Program on March 2, 2022, that they believed a source had been found in scrap metal unloaded at their facility. At the time of the report, they were unable to identify the customer from whom the scrap metal was purchased.

"Intact labeling provided general license information, Am-241, manufactured by NDC in California, source SN 7090AR, Model 103, 5.55 GBq (150 mCi) in April 2011. The device manufacturer identified the device and tracked its shipment to Arkansas' GL-0010, Anchor Packaging Company located in Paragould, Arkansas.

"Radiation surveys conducted by recycling facility personnel indicated a reading of 10 microR/hr at approximately three feet from the item.

"Health Physicists from the Arkansas Radiation Control Program responded to WW Recycling on the morning of March 3, 2022.

"A metal drum container clearly labeled with a radioactive material sign, observed to be closed, in good repair was surveyed by ADH personnel. The top of the metal drum registered 185 microR/hr. The reading at the bottom sealed edge of the drum reached 85 milliR/hr. The shutter appears to be missing. There are no known exposures.

"The device remains secured at the recycling center and this event remains open while Anchor GL-0010 pursues disposal through a specific licensee authorized to perform this sort of activity/retrieval.

"Reporting Requirement: Arkansas State Board of Health Rules for Control of Sources of Ionizing Radiation RH-402.c.5. and 10 CFR Part 31.5(c)(5)."

State Event Report ID No.: AR-2022-04

* * * UPDATE ON 3/22/2022 AT 1534 EDT FROM CHRISTY STEWARD TO BRIAN LIN * * *

"On March 17, 2022, WW Recycling in Marmaduke, Arkansas, contacted the Arkansas Department of Health - Radiation Control Section to report the discovery of a second gauge. Photos received March 18, 2022, confirm this gauge to be similar to the generally licensed fixed gauge discovered then reported to the Department on March 2, 2022 (NDC model 103X, SN 13629, Am-241, 5.55 GBq). SN 13629 was once registered to Anchor Packaging Company in Paragould, Arkansas, and later documented as disposed. The gauge was found in the remnants of the original load where the first gauge was found. The gauge was placed into a radioactive material - labeled small drum and secured in the remote storage building where the initial gauge is being stored (also in a small drum).

"WW Recycling personnel measured 40 microR/hr, via their Ludlum 193-6, on contact with the outside of the wall closest to the two drums. Inside the building, about 7 feet away from the drums, radiation levels begin increasing above background. The photo indicates the shutter to be attached but not closed. There are no known exposures.

"Reporting requirements: Arkansas State Board of Health Rules for Control of Sources of Ionizing Radiation - RH-1501.a.1.A. and RH-1501.b. pursuant to RH-409.c.10. "

EMERGENCY FEEDWATER SYSTEM ACTUATION

The following information was provided by the licensee via email and phone:

"At 1625 [EST] on 2/13/2022, with Unit 2 in Mode 3 at 0 percent power and plant heat up to normal operating temperature in progress, an actuation of the Emergency Feedwater System (EFW) occurred. The reason for the EFW auto-start was lowering water level in the 2A and 2B Steam Generators due to failure of the 2A Main Feedwater Pump to respond as required to maintain Steam Generator water level as Steam Generator pressure increased during plant heat up. The 2A and 2B Motor Driven Emergency Feedwater (MDEFW) pumps automatically started as designed when the 'low steam generator level' signal was received for the 2A and 2B Steam Generators.

"Following further evaluation, it was determined that a valid EFW actuation occurred, therefore this event is being reported as a late 8-hour non-emergency notification of a valid actuation of the EFW system in accordance with 10 CFR 50.72(b)(3)(iv)(A).

"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."
