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 - STUCK SHUTTER GAUGE
The following information was provided by the Iowa Department of Public Health via email:
"A stuck shutter was discovered Wednesday, March 2nd on the B-gauge, shutter 1. Entry to the gauge house has been prohibited per protocol. Measurements indicate an increase dose rate relative to background at the south side adjacent to the gauge and shutter 1 position, with a maximum reading of 0.11 mR/hr. The licensee's service provider, SenTek, has been requested to perform emergency repair work. The B-Gauge was repaired last night around 1900 CST. The shutter failed to close due to the solenoid valve that opens and closes the shutter, which would not vent pressure. The failed solenoid valve was replaced by a new valve. The project to replace these gauges with x-ray technology is ongoing and on track to be replaced by first quarter, 2023."

HIGH PRESSURE COOLANT INJECTION (HPCI) INOPERABLE
The following information was provided by the licensee:
"At 2013 EST on March 9, 2022, the HPCI System was declared inoperable following evaluation of routine HPCI surveillance testing data indicating that the required response time for reaching rated conditions was not met. Therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v)(D). The Reactor Core Isolation Cooling (RCIC) System and Automatic Depressurization System (ADS) are operable.
"There was no impact on the health and safety of the public or plant personnel. Investigation is in-progress to determine the cause.
"Unit 1 is not affected by this event. Unit 1 is in a refueling outage.
