INVALID SYSTEM ACTUATION
The following information was provided by the licensee via fax:
"Auxiliary Feedwater Pump #12 actuation and isolation of the Steam Generator Blowdown for 'A', 'B' and 'C' Steam Generators.
"Per 10 CFR 50.73(a)(1), the telephone notification is made under 10 CFR 50.73(a)(2)(iv)(A) for an invalid actuation. On 7/28/2022 at 1705 CDT, the Unit 1 Control Room received alarm SPQD0183 'SG LO-LO LVL TRN B ACT' and actuation of the Auxiliary Feedwater Pump #12 and isolation of the Steam Generator Blowdown for 'A', 'B' and 'D' Steam Generators. This event was classified as an unplanned entry into Technical Specification Shutdown LCO equal to or less than 24 hours 'Simple Restoration', due to the availability of CRMP.
"This alarm occurred several times and with each occurrence the alarm was short lived (1 second or less). Operations placed Auxiliary Feedwater Pump #12 in the Pull-To-Lock position to prevent starting of the pump with each alarm occurrence. During troubleshooting it was determined that SSPS Logic 'R' train was generating the intermittent alarm condition. A Logic board and a Safeguard Driver board were replaced which was identified as the possible cause. Operations performed applicable sections of the Logic test to ensure SSPS 'R' train operable.
"The event had no effects/consequences on the unit. The Logic board and Safeguard Driver board in SSPS 'R' train were both replaced as the possible causes, and therefore both boards were sent to Westinghouse to determine which board was at fault."
The NRC Resident Inspector has been notified.

AGREEMENT STATE REPORT - SOURCES FOUND IN UNLOCKED CONTAINER
The following information was provided by the Florida Bureau of Radiation Control (BRC) via email:
"Indian River County [Radiological Emergency Preparedness] (REP) [employee] called this afternoon regarding a small cardboard box, about half the size of a shoebox, with several sources inside being stored in a small, unlocked metal storage shed on property of the Emergency Operations Center. Inside the small cardboard box are six small cylindrical containers three of which are labeled `Unrefined uranium minerals emit alpha, beta, and gamma radiation', one 'No Salt' container, and the other three are smaller metal containers not labeled. Also in the box are several typical plastic check sources inside plastic bags and one wooden gamma standard check source. REP reported an 'on contact' reading with the box a dose rate of around 280 microR/hr and with a gloved hand, removed all the items inside the box and reported a contamination reading of just over 400 cpm. REP has requested a response from the BRC to handle. The Central Inspection Office has been notified and will respond."
