EN Revision Text: DEGRADED CONDITION DISCOVERED ON SHUTDOWN COOLING TEST LINE
The following information was provided by the licensee via email:
"On 1/15/2022 at 2320 [EST] during the planned F108 outage on Browns Ferry Nuclear Plant Unit 1, personnel entered the Unit 1 Drywell for leak identification. Personnel discovered a through-wall piping leak on a 3/4 inch test line upstream of the test valve. This 3/4 inch test line is located on the RHR Shutdown Cooling & RHR Return Line to the reactor vessel and is classified as ASME Code Class 1 Piping.
"This constitutes an 8-hour NRC notification in accordance with 10 CFR 50.72(b)(3)(ii)(A) - Any event or condition that results in the condition of the nuclear power plant, including its principal safety barriers, being seriously degraded.
"The NRC resident has been notified."

EN Revision Text: AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE
The following report was received from the California Department of Public Health via email:
"On Monday, January 17, 2022, the licensee's radiation safety officer reported the theft of a CPN MC-1DR (MD30406938) containing sealed sources of Cs-137 (10 mCi) and Am-241:Be (50 mCi), leak tested 4/2021. The theft occurred overnight between Friday and Saturday 1/14/2022 - 1/15/2022 at an authorized gauge user's (AU) residential home. The AU returned home urgently on Friday due to a family member's illness. The AU did chain the gauge case to the door inside the truck cab but failed to lock the truck before entering his home. The AU discovered that the gauge case was missing early Saturday morning while the truck was parked in the driveway of the home. The CPN nuclear gauge handle was locked to prevent operation, the gauge was locked in its transport case, and the transport case was chained to the door inside the truck cab, but the chain was cut and case/gauge was taken, apparently the only item stolen. The gauge and case had a company name and phone number label adhered to it in case of loss or theft. A police report was filed with the Corona police department (22-03047). The licensee will submit a lost/reward ad in the local paper/website and gather additional information for the follow up investigation."
California Event Number: 011722
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.
