Event Notification Report for March 11, 2021

AGREEMENT STATE REPORT - LOST AND FOUND GAUGE

The following is a summary of a report received from the California Department of Public Health (the Department) via email:

The Department was notified that a Troxler model 3440, Serial Number 22188 (9 mCi. Cs-137, 44 mCi. Am:Be-241) had been lost when the operator left the worksite believing the gauge was in the bed of the truck. At approximately 1430 PST, the licensee reported the gauge had been located at the work site and returned. The licensee is investigating the event and the Department will review their findings.

California Report ID: 5010-030321

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 P-32 SHIPMENT

The following was received from Iowa Department of Public Health via email:

"On February 3, 2021, the University of Iowa received a package from [the common carrier] that was labeled as one of the standing orders of 1 millicurie P-32 dCTP for the Pathology Lab at UIHC [(University of Iowa Health Care)]. The outer label was correct and the packing slip inside was correct, however the contents of the package was actually a prescription of Enbrel intended for an individual in Illinois.
Further, the contents had obviously been repacked. It arrived in a large [common carrier] box, much bigger than required for the P-32 order or the Enbrel. Also, the top of the original package that held the P-32 had been torn off and affixed to the replacement box in an adhesive pouch. The licensee contacted both [the common carrier] and the pharmaceutical company that shipped the Enbrel. [The common carrier] returned to retrieve the Enbrel but haven't heard anything about the location of the original P-32 order. Perkin Elmer sent a replacement shipment of P-32 to the licensee. On February 10, 2021, [the common carrier] sent an email to the licensee notifying them that the original shipment of P-32 has not been located and they were closing the case. On March 4, 2021, the Iowa Department of Public Health contacted the University of Iowa Radiation Safety Officer (RSO) and was informed by the RSO that the original shipment of P-32 is still missing. The activity of the P-32 as of March 4, 2021 is approximately 244 microcuries."

HIGH PRESSURE COOLANT INJECTION INOPERABLE

"At 0313 EST on March 9th, 2021, during performance of Unit 1 High Pressure Coolant Injection (HPCI) valve exercising, the inboard vacuum breaker isolation valve did not stroke closed as expected, but remained mid-position. The affected penetration of primary containment was isolated by closing the outboard HPCI vacuum breaker isolation valve. This results in an unplanned inoperability of the Unit 1 HPCI system.

"This is being reported as a loss of an entire safety function condition in accordance with 10CFR50.72(b)(3)(v)(D).

The licensee notified the NRC Resident Inspector.

Unit 1 is in a 14-day LCO for Tech Spec 3.5.1(d), HPCI inoperability. Tech Spec 3.6.1.3(a), Containment Penetration Valve, was completed with closing the outboard HPCI vacuum breaker isolation valve. The Units are in a normal offsite power line-up.

SUSPECTED TECH SPEC POWER LIMIT EXCEEDED

At 1027 CST on 3/8/21, while the reactor was at 900 kW at steady state, a sample was pulled before the planned down power was executed. As a result, the reactor may have exceeded the 1000 kW limit for one second by 1 kW per Tech Spec 3.1. The duration was recorded on the strip chart recorder.

The licensee has notified the NRC Project Manager (Patrick Boyle).

60-DAY OPTIONAL TELEPHONIC NOTIFICATION FOR INVALID CONTAINMENT VENTILATION ISOLATION ACTUATION

"This 60-day telephone notification is being submitted in accordance with 10 CFR 50.73(a)(1) and 50.73(a)(2)(iv)(A). The event was an invalid actuation of the Unit 1 Containment Ventilation Isolation (CVI) system.

"On January 11, 2021 at 1152 Eastern Standard Time (EST) with Unit 1 at 100% power, Train 'A' of the CVI System actuated due to an invalid high radiation signal from 1-RM-90-130, Containment Purge Air Exhaust Monitor. The cause of the signal was determined to be a failed sample pump associated with the radiation monitor. 1-RM-90-130 was in service at the time of the invalid signal. The Train 'A' Containment Ventilation Isolation signal was a full actuation of that train and the system functioned as designed.

"Prior to and following the invalid high radiation alarms, all radiation monitors except 1-RM-90-130 were stable at their normal values; therefore, the CVI was invalid. Control room operators performed appropriate checks and confirmed that all required automatic actuations occurred as designed. The failed pump was replaced and returned to service. This event was entered into the corrective action program as CR 1663398.

"The NRC Resident Inspector was notified."

NOTIFICATION OF ENVIRONMENTAL REPORT TO ANOTHER GOVERNMENT AGENCY

"On March 10, 2021, Exelon reported an unpermitted release of a radionuclide (i.e., tritium) into the groundwater within the site boundary at Quad Cities Nuclear Power Station to the Illinois Environmental Protection Agency (IEPA) and the Illinois Emergency Management Agency (IEMA) in accordance with Illinois state regulations. There has been no detection of the release beyond the site boundary. The suspected source for the increased groundwater tritium levels is an onsite water storage tank or pipe; however, an investigation is in progress and the exact cause and source is not yet known. The increase in groundwater tritium concentration does not exceed any NRC regulations or reporting criteria. This notification is being made solely as a four-hour, non-emergency notification for a Notification of Other Government Agency.

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