University of Florida Training Reactor Annual Report for Calendar Year 2022 The following annual report is submitted in accordance with Section 6. 7.1 of the UFTR Technical Specifications.
Summary of Reactor Operations:
Total Energy Output for CY2022:
Cumulative Energy Output Since Conversion to LEU:
21,501 kW-hrs 88,702 kW-hrs Routine operations were conducted throughout the year with brief outages for maintenance and surveillances with an extended outage for scheduled in-core fuel inventory and a fresh fuel addition to the core.
Unscheduled Shutdowns:
There were no unscheduled shutdowns during CY2022.
Major Maintenance:
A listing of all major maintenance is presented in Table I. The Date Opened entry is when the Maintenance Log Page (MLP) was opened; in a few cases, this date may be one or more days after the original problem was noted. The Date Closed entry is the day the MLP was closed which can also be one or more days after work completion. Update of CY2021 Report, MLP 21-8 was closed on 5/18/22.

Changes, Tests, and Experiments Implemented under 10 CFR 50.59:
A listing of changes, tests, and experiments implemented under 10 CFR 50.59 is presented in Table II. All changes, tests, and experiments implemented during CY2022 screened-out from full evaluation.
Table II Number Date Summary Approved 22-1 5/23/2022 Procedure Change: SOP-A.1 Pre-Operational Checks, change sequence for cycling console power.
22-2 5/24/2022 Procedure Change: SOP-E.2 Calibration of Rx Measuring Channels, change connection point for measuring compensating voltage.
22-3 6/07/2022 Procedure Change: SOP-A.9 Startup using Inverse Multiplication, change units of reactivity.
22-4 7/06/2022 Modification: Use of MCNP6.2 for fuel addition calculations, newer version than that used for license renewal FSAR information.
22-5 7/06/2022 Modification: Load a fresh partial fuel bundle into the core.
22-6 9/21/2022 Modification: Confinement hole created for rabbit system conduit installation.
22-7 10/31/2022 Procedure Change: SOP-A.2 Reactor Startup, changes needed based on adding new fuel to the core.
22-8 10/31/2022 Procedure Change: SOP-A.3 Operation at Power, editorial changes to be consistent with SOP-A.2 revision.
22-9 10/31/2022 Procedure Change: SOP-B.1 Radiological Emergency, editorial changes and changes due to new power supply references.
22-10 10/31/2022 Procedure Change: SOP-B-2 Emergency Procedure - Fire, similar changes made from SOP-B.l revision.
Radioactive Effluents:
Liquid Waste No wastewater releases were made during CY2022.
Gaseous Waste The total activity of Argon-41 released during CY2022 was 95. 75 curies. Using the calculation method described in the UFSAR, the maximum potential dose to a member of the public from UFTR Ar-41 emissions during CY2022 was 0.4 mrem/year. This is significantly less than 25% of the ALARA constraint of 10 mrem/yr.

Environmental Surveys:
In addition to periodic radiation surveys using hand-held instruments, environmental monitoring is accomplished using radiation dosimeter badges. Areas monitored are located around the exterior of the Reactor Building (RB) and nearby buildings, including the Nuclear Sciences Building (NSB), the Rhines Hall (RH), Weil Hall (WH), Weimer Hall (WmH), and Wertheim Engineering Lab (WEL). The environmental dosimeter reports are tabulated and presented in Table III. Dose equivalents below the minimum measurable quantity are reported as "M".
