EN Revision Text: HPCI INOPERABILITY
"At 0634 EDT on August 11, 2021 [high pressure coolant injection] HPCI was declared inoperable due to a pump flow controller problem. The cause of the controller problem is unknown at this time and is under investigation.
"[Reactor core isolation cooling] RCIC was verified operable per Tech Spec 3.5.1 E.1.
"This report is being made pursuant to 10CFR50.72(b)(3)(v)(D) based on an unplanned HPCI inoperability.
"There was no impact on the health and safety of the public or plant personnel.
"The NRC Resident Inspector has been notified."

"The purpose of this notification is to retract a previous report made on August 11, 2021 (EN 55403). At 0634 EDT on August 11, 2021, an unplanned inoperability of the High Pressure Coolant Injection system (HPCI) was reported pursuant to 10 CFR 50.72(b)(3)(v)(D) by EN 55403. HPCI was declared inoperable due to receipt of an alarm associated with the pump flow controller. The HPCI system operating procedure states that HPCI should be declared inoperable when this alarm is received. The cause of the alarm, a loose transmitter connection, was identified and corrected. Following clearance of the alarm, HPCI was declared operable at approximately 1930 EDT on August 11, 2021.
"This alarm indicated a fault in the signal from the transmitter to the HPCI flow controller; in this case, the HPCI flow controller would have continuously called for maximum HPCI flow. The controller is configured with a high limiter to prevent an overspeed trip. An engineering evaluation of the event identified that HPCI was capable of performing its required safety functions while this alarm was present. The condition was that the HPCI flow controller would have continuously called for maximum HPCI flow upon HPCI initiation, however operators would be able to manually control HPCI flow upon HPCI initiation. Additionally HPCI would have run until Reactor Pressure Vessel (RPV) level reached Level 8 where it would trip until RPV level decreased to Level 2 then automatically restart."
The licensee notified the NRC Resident Inspector.

EN Revision Text: AGREEMENT STATE REPORT - STOLEN XRF LEAD PAINT ANALYZER
The following was received from the Maryland Department of Environment Radiological Health Program via email:
"On August 11, 2021, at approximately 1630 EDT, the Radiological Safety Officer (RSO) who is the authorized user put down the locked [Lead-Paint Analyzer] (LPA) (XRF case, with the XRF device inside) on the sidewalk next to his vehicle that was parked on the corner of Pennsylvania Avenue and Laurens Street in Baltimore City, Maryland after testing the exterior of a property nearby on Pennsylvania Avenue. The RSO was moving a few items around the trunk of his car to better place a ladder and went to grab the XRF case, it was gone. The RSO made the effort to check for the LPA around the block and asked individuals in the area, but the attempt was unsuccessful.
"On August 12, 2021, at about 1415 EDT the Maryland Department of the Environment Radiological Health Program (MDE/RHP) was contacted via telephone by the RSO of 100 percent Lead Inspections that a portable Lead-Paint Analyzer (LPA) was missing from 100 percent Lead Inspections, LLC (license number MD-05-244-01). The Lead-Paint Analyzer was identified as Viken Detection (formerly known as Heuresis), model pb200i XRF, device serial number 2861 with nominal activities of 6 milliCi of Co-57 source (on 11/15/2020), and source model A3901-02 and source serial number T3-296.
"The event has been later reported to the Baltimore City Police Department, in Baltimore; the Incident Number 1-210803237.
"MDE/RHP will conduct a reactive investigation."
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.
