Appendix A to Facility License No. R-56 Technical Specifications and Bases University of Florida Training Reactor Docket No.50-083 March 31, 2017 Page 1 of 43 University of Florida Training Reactor March 31, 2017

TECHNICAL SPECIFICATIONS 1.0 Introduction 1.1 Scope This document constitutes the Technical Specifications for Facility License No. R-56 as required by 10 CFR 50.36 and supersedes all prior UFTR Technical Specifications. This document includes the bases to support the selection and significance of the specifications. Each basis is included for information purposes only. They are not part of the Technical Specifications, and they do not constitute limitations or requirements to which the licensee must adhere.

1.2 Definitions ACTIONS: Actions shall be that part of a Specification that prescribes Required Actions to be taken under designated Conditions within specified Completion Times. The Completion Time is the amount of time allowed for completing a Required Action referenced to the time of discovery of a situation.

CHANNEL: A channel is the combination of sensor, line, amplifier, and output devices that are connected for the purpose of measuring the value of a parameter.

CHANNEL CALIBRATION: Channel calibration shall be the adjustment, as necessary, of the channel output such that it responds within the necessary range and accuracy to known values of the parameter that the channel measures. The channel calibration shall encompass all devices in the channel required for channel OPERABILITY and the CHANNEL TEST.

CHANNEL CHECK: Channel check shall be the qualitative verification of acceptable performance by observation of channel behavior, or by comparison of the channel indication and status with other independent channels measuring the same parameter.

CHANNEL TEST: A channel test shall be:

a. Analog and bistable channels - the introduction of a signal into the channel for verification that it is OPERABLE.
b. Digital computer channels - the use of diagnostic programs to test digital computer hardware and the introduction of simulated process data into the channel for verification that it is OPERABLE.

CORE ALTERATION: Core alteration shall be the movement of any reactor fuel assemblies, graphite moderator elements, experimental facilities, or control blade assemblies within the reactor core region in MODE 5.

CORE CONFIGURATION: Core configuration shall include the number, type, or arrangement of fuel assemblies, graphite moderator elements, experimental locations, and control blades occupying the core region.

DAMAGED FUEL: A fuel assembly shall be identified as damaged if the cladding is breached resulting in fission product release or if visual inspection of the fuel indicates cladding blistering, excessive swelling, excessive bulging, excessive deformation, cladding holes, cladding tears, or cladding breaches of any kind.

Page 2 of 43 University of Florida Training Reactor March 31, 2017

EXCESS REACTIVITY: Excess reactivity shall be that amount of reactivity that would exist if all control blades were moved to the maximum reactive condition from the point where the reactor is exactly critical (keff = 1). When calculating excess reactivity, no credit shall be taken for negative experiment worth, temperature effects or xenon poisoning.

EXPERIMENT: Any evolution, hardware, or target (excluding devices such as detectors or foils) that is designed to investigate non-routine reactor characteristics or that is intended for irradiation within an irradiation facility. Hardware rigidly secured to the core or shield structure so as to be a part of its design to carry out experiments is not normally considered an experiment.

FUEL DEFECT: A fuel defect shall be any unintended change in the physical as-built condition of the fuel with the exception of normal effects of irradiation (e.g., elongation due to irradiation growth or assembly bow) that do not render the fuel inoperable. Examples include unusual pitting, unusual bulging, missing or broken bolts, missing or broken spacers, missing or broken combs, missing or broken welds, or unusual corrosion.

MOVABLE EXPERIMENT: A movable experiment is one where it is intended that all or part of the experiment may be moved into or adjoining the core or into and out of the core while the reactor is in MODES 1 or 2.

OPERABLE - OPERABILITY: A system or component shall be operable or have operability when it is capable of performing its intended function.

OPERATING: Operating means a component or system is performing its intended function.

RATED THERMAL POWER (RTP): RTP shall be a total reactor core heat transfer rate to the reactor coolant of 100 kWt.

REACTIVITY WORTH OF AN EXPERIMENT: The reactivity worth of an experiment is the value of the reactivity change that results from the experiment being inserted into or removed from its intended position.

REACTOR CELL: The Reactor Cell is the confinement enclosure around the reactor structure that is designed to limit the release of effluents between the enclosure and its external environment through defined pathways.

REACTOR OPERATING: The reactor is operating whenever it is not in MODES 3, 4, 5 or defueled.

Reactor operation at greater than or equal to 1% RTP shall be called MODE 1. Reactor operation at less than 1% RTP shall be called MODE 2.

REACTOR SHUTDOWN: The reactor is shutdown if it is subcritical by at least 760 pcm with the core at ambient temperature with the reactivity worth of xenon equal to zero and with the reactivity worth of all installed experiments included. The reactor shutdown condition shall be called MODE 3.

Page 3 of 43 University of Florida Training Reactor March 31, 2017

REACTOR SECURED: The reactor is secured when with fuel present in the reactor there is insufficient water moderator available in the reactor to attain a keff greater than 0.8 or there is insufficient fuel present in the reactor under optimum available conditions of moderation and reflection to attain a keff greater than 0.8 or the reactor is shutdown with all control blades fully inserted; and the following conditions exist:

a. the console key switch is in the OFF position and the key is removed from the switch; and
b. no work is in progress involving fuel, core structure, installed control blades, or control blade drives unless they are physically decoupled from the control blades; and
c. no experiments are being moved or serviced that have, on movement, a reactivity worth exceeding 720 pcm.

The reactor secured condition shall be called MODE 4.

REACTOR OUTAGE: The reactor is in an outage condition anytime less than two layers of concrete block shielding are fully installed over the top of the core area with fuel in the core. The reactor outage condition shall be called MODE 5.

SHALL, SHOULD, and MAY: The word "shall" is used to denote a requirement; the word "should" is used to denote a recommendation; and the word "may" is used to denote permission, neither a requirement nor a recommendation.

SHUTDOWN MARGIN: Shutdown margin is the minimum shutdown reactivity necessary to ensure the reactor can be made subcritical by means of the reactor control and trip systems starting from any permissible operating condition with the most reactive blade in its most reactive position and that the reactor will remain subcritical without further operator action. When calculating shutdown margin, no credit shall be taken for negative experiment worth, temperature effects or xenon poisoning.

STRUCTURE, SYSTEM, OR COMPONENT (SSC): A structure is an element, or a collection of elements, to provide support or enclosure, such as a building, free-standing tanks, basins, dikes, or stacks.

A system is a collection of components assembled to perform a function, such as piping, cable trays, conduits, or ventilation. A component is an item of mechanical or electrical equipment, such as a pump, valve, or relay, or an element of a larger array, such as a length of pipe, elbow, or reducer.

UNSCHEDULED SHUTDOWN: An unscheduled shutdown is any unplanned shutdown of the reactor caused by actuation of the reactor trip system, operator error, equipment malfunction, or a manual shutdown in response to conditions that could adversely affect safe operation, not including shutdowns that occur during testing or checkout operations.

2.0 Safety Limit and Limiting Safety System Settings 2.1 Safety Limit Applicability: MODES 1 and 2.

Objective: To ensure fuel cladding integrity.

Specification: The fuel and cladding temperatures shall not exceed 986°F (530°C).

Basis: The safety limit is based on measurement of first fission product release from the fuel at or above the blister threshold temperature described in NUREG-1313.

2.2 Limiting Safety System Settings Applicability: MODES 1 and 2.

Objective: To ensure automatic action terminates the abnormal situation before the safety limit is challenged.

Specification: According to Table 2.2-1.

Basis: Due to the inherently safe core design and low EXCESS REACTIVITY, postulated reactivity insertion event analyses indicate no automatic control or safety functions are needed to prevent reaching the Safety Limit (Ref. SAR Section 13.2). Therefore, to allow for generation of a reasonable set of Technical Specifications, and provide defense-in-depth, the fundamental reactor parameters of power, temperature, and flow were conservatively chosen for incorporation as LSSSs. These very conservative settings ensure normal reactor operation remains within the assumptions of the thermal hydraulic analysis for normal operation (ONBR > 1) as described in SAR Section 4.6.

Table 2.2-1 Limiting Safety System Settings FUNCTION ALLOWABLE VALUE

1. High Reactor Power Trip 110% RTP
2. Low Reactor Coolant Flow Trip 41 gpm
3. High Reactor Coolant Bulk Inlet Temperature Trip 102oF Page 6 of 43 University of Florida Training Reactor March 31, 2017

3.0 Limiting Conditions for Operation and Surveillance Requirements 3.0.1 LCO Applicability Applicability: Any MODE or specified condition in which the applicable SSC or variable is required to be OPERABLE or within specified limits.

Objective: To provide general LCO requirements and guidance to ensure timely and appropriate operator action.

Specification:

1. LCOs shall be met during the MODES or other specified conditions in the Applicability, except as provided in LCO 3.0.1.2.
2. Upon discovery of a failure to meet an LCO, the Required Actions of the associated Conditions shall be met, except as provided in LCO 3.0.1.5.

If the LCO is met or is no longer applicable prior to expiration of the specified Completion Time(s), completion of the Required Action(s) is not required.

3. When an LCO is not met and the associated ACTIONS are not met, or an associated ACTION is not provided, the reactor shall be placed in a MODE or other condition in which the LCO is not applicable. Action shall be initiated within 2 minutes of discovery of failure to meet the LCO. Exceptions to this Specification are stated in the individual Specifications.
4. Suspension of CORE ALTERATIONS, irradiated fuel movement, irradiated fueled EXPERIMENT movement, movement of experiments with significant potential for airborne releases, or movement of concrete block shielding over the top of the core in MODE 5, shall not preclude completion of movement of the component to a safe position.
5. When an LCO is not met solely due to interruption of recording function or indicating lamp function, the Conditions and Required Actions associated with this LCO are not required to be entered provided the recording function or indicating lamp function is restored within 15 minutes.
6. When in MODES 1 or 2, shutdown of the reactor should never be delayed when multiple unrelated LCOs are not being met simultaneously, except as provided in LCO 3.0.1.5.

Basis: LCOs 3.0.1.1, 3.0.1.2, 3.0.1.5, and 3.0.1.6 provide general LCO requirements and guidance. LCO 3.0.1.3 provides a 2-minute allowed action time upon discovery that an LCO is not met and the associated ACTIONS cant be met or an associated ACTION is not provided. LCO 3.0.1.4 provides the operator with prioritization guidance and an exception to allowed action completion time(s) to allow for safe completion of a component movement already in-progress.

3.0.2 Surveillance Requirement Applicability Applicability: Any MODE or specified condition in which the applicable SSC or variable is required to be OPERABLE or within specified limits.

Objective: To confirm SSCs and variable properties required by Technical Specifications are OPERABLE and within specified limits.

Specification:

1. Failure to meet a surveillance, whether such failure is experienced during the performance of the surveillance or between performances of the surveillance, shall be failure to meet the associated LCO. Failure to perform a surveillance within the specified frequency shall be failure to meet the LCO except as provided in LCOs 3.0.2.2 and 3.0.2.3.
2. SRs may be deferred during MODES or other specified conditions in which a SSC or variable is not required to be OPERABLE or within specified limits; however, they shall be completed prior to entry into a MODE or other specified condition in which the SSC or variable is required to be OPERABLE or within specified limits unless entry into the MODE or other specified condition is required for performance of the surveillance as provided in LCO 3.0.2.3.
3. The following SRs require entry into the applicable MODE or other specified condition for performance of the surveillance. These SRs shall be performed as soon as practicable after entry into the MODE or other specified condition required for performance of the surveillance:

3.1 Reactor Core Reactivity Parameters Applicability: MODES 1 through 5.

Objective: To ensure the reactor can be made subcritical and to ensure the safety limit shall not be exceeded.

Specification: According to Table 3.1-1.

Basis: The value of SHUTDOWN MARGIN assures the reactor can be made subcritical from any operating condition. The value of EXCESS REACTIVITY allows flexibility to operate the reactor without the need to add fuel on a frequent basis while maintaining the installed core EXCESS REACTIVITY within the bounds of the analysis described in SAR Section 13.2.

3.2.2 Reactor Trips Applicability: MODES 1 and 2.

Objective: To specify the minimum required OPERABLE reactor trips.

Specification: According to Table 3.2.2-1.

Basis: LCOs 3.2.2.1, 3.2.2.2, and 3.2.2.3 ensure reactor operation remains bounded by the thermal hydraulic analysis described in SAR Section 4.6. LCO 3.2.2.4 provides redundancy to LCOs 3.2.2.1, 3.2.2.2, and 3.2.2.3. LCO 3.2.2.5 ensures early termination of a reactivity insertion event originating from low power levels. LCO 3.2.2.6 provides redundancy to LCO 3.2.2.2 and acts as a blade withdrawal inhibit until the minimum core water level is reached. The Manual trip allows the operator to quickly shutdown the reactor if an unsafe or abnormal situation occurs.
