Scram time is the elapsed time between reaching a limiting safety system setting and a specified controlrod movement.

1.27 Shall. Should. and May The word shall is used to denote a requirement. The word should is used to denote a recommendation. The word may is used to denote permission, neither a requirement nor a recommendation.

1.28 Shutdown Marcin Shutdown margin shall mean the minimum shutdown reactivity necessary to provide confidence that the reactor can be made or maintained subcritical by means of the control and safety systems starting from any permissible operating condition

.although the most reactive rod is in its most reactive position, and that the reactor will remain subcritical without further operator action.

1.29 Shutdown. Unscheduled An unscheduled shutdown is any unplanned shutdown of the reactor caused by actuation of the reactor safety system, operator error, equipment malfunction, or a manual shutdown in response to conditions which could adversely affect safe operation, not including shutdowns which occur during testing or check-out operations.

.1 1.30. Startup Startup is the sequence of procedures and operations to be completed whenever the reactor is to be taken from a Reactor Secured condition.

' 1.31' Surveillance Activities Surveillance activities will usually have a prescribed frequency and scope to demonstrate performance of systems required under Limiting Conditions for Operations.

In general, two types of surveillance activities are specified, operability checks'and calibrations. Operability checks are generally specified as monthly to quarterly.

Calibrations are generally specified as annually to biennially.

1.32 Time Intervals '

~

To provide operational flexibility, where time intervals for surveillance and audit activities are specified in the document, maximum intervals shall not exceed 125%

of the specified interval. Established frequencies shall be maintained over the long term.

June 1986 edition P

R;ed Reactor Facility Technical Specifications Page 10 Surveillance activities (except those specifically required for safety when'the reactor is secured) may bp deferred when the reactor is secured, however, they shall be completed prior to reactor startup. Surveillance activities scheduled to occur during an operating cycle which cannot be performed with the reactor operating may be deferred to the end of the cycle.

1.33 Value. Measured The measured value is the value of a parameter as it appears on the output of a channel.

1.34 Value. True The true value is the actual value of a parameter.

1.3S Zero Power Critical The reactor is zero power critical when the reactor is exactly critical and the reactor linear power channel reads less than or equal to ten (10) watts. This is the operational point where the excess reactivity, or core excess, is measured during reactor operations.

^

2.1 Safety Limit Applicability.

- This specification applie,s to the reactor power.

~ Objective The objective is to define the maximum reactor power that can be permitted with confidence that no damage to the fuel element cladding will result.

Specification (s)

The maxiinum reactor po' er shall not exceed 250 kilowatts. However, for the w

, purpose of testing the 110% full power safety scrams, an exception shall be made to allow the reactor to be operated at power levels not to exceed 287.5 kilowatts during the testing period.

t Basis t

The safety limit for the standard TRIGA fuel is based on calclulations and expenmental eyidence. The results indicate that the stress in the cladding due to 1

hydrogen pressure from the dissociation of zirconium hydride will remain below l

the ultimate stress provided that the temperature of the fuel does not exceed 1150 C and the fuel cladding does not exceed 500*C.

,4, Appendix E of"THE REED COLLEGE REACTOR FACILITY (TRIGA MARId)

SAFETY ANALYSIS REPORT, April 15,1967" (SAR) gives 225*C as the I

approximate maximum fuel temperature for operation at 250 kilowatts. This conservative limit will assure a cladding temperature less than 500 C under all design basis accident conditions (step insertion of all available excess reactivity or instantaneous less Of Cooling Accident). Sec. tion 2.1 of the SAR gives 150 C as l

the maximum fuel temperatum for an instantaneous Loss of Cooling Accident after operation at 250 kilowatts for infinite time prior to the accident. The equilibrium pressure resulting from fission gases, entrapped air, and hydrogen at 150 C is less than 30 psi. Section 7.1 of the SAR gives a maximum measured fuel temperature A

less than 500 C for a 2.25% Aluk ($3.00) step insertion.

Thermal and hydraulic calculations indicate that standard TRIGA fuel elements may be safely operated at po'wer levels in exc~ess of 1500 kilowatts with natural-convection cooling. Details on the performance of TRIGA fuel are given in the SAR and in papers available as " Fuel Elements for Pulsed TRIGA Research c

Reactors", Simnad, er al., Nuclear Technology,2.1, 31 (January,1976), and "The U-ZrH Alloy:. Its Properties and Use'in TRIGA Fuel", GA Project No. 4314 x

d.

During heat exchanger operation, the pressure in the secondary system (measured at the secondary basket filter outlet) is less than 35 kPa (5 psi differential) greater than the pressure in the primary system (measured at the primary filterinlet).

Basis The bulk water temperature constraint assures that sufficient core cooling a.

Equipment shall be operable to isolate the reactor bay by closure of a.

ventilation supply and exhaust dampers.

b.

The double doors shall be closed and barred; the emergency exit i

door shall be closed and locked (the door shall be equipped with an emergency release mechanism); and the door to the control room shall be closed except forpersonnel access.

Upon detection of elevated radioactivity levels by the Continuous c.

Air Monitor or the Gaseous Stack Monitor, the ventilation system shall automatically close supply air dampers and initiate restricted air exhaust from the reactor bay in order to maintain a negative pressure relative to ambient conditions. Air released during this restricted air exhaust shall be filtered through high efficiency particulate adsorption filters.

Basis Tlie specifications for exhaust ventilation and confinement of the reactor bay provide control for airborne radioactive releases during both routine and non-routine operation.

3.3.3 Radiation Monitoring Systems Applicability This specification applies to the radiation monitoring conditions in the reactor bay during reactoroperation.

Objective The objective is to monitor the radiation and radioactivity conditions in the area of the reactor.

I Specification (s)

The reactor shall not be operated unless minimum conditions for radiation measurement are operable. The following minimum conditions shall exist:

The portable ion-chamber type radiation monitor may be substituted for the Area Radiation Monitor during periods of maintenance or repair.

f.

The Gaseous Stack Monitor may be substituted for the Continuous Air Monitor during periods of maintenance or repair.

Basis The radiation monitors provide information to operating personnel of impending or existing hazards from radiation. This should provide sufficient time to evacuate the facility or take the necessary steps to maintain the exposure of personnel as low.as practicable and to control the release of radioactivity. The Gaseous Stack Monitor mitiates confinement upon alarm as does the Continuous Air Monitor. Therefore, substitution during maintenance or repair provides the same capability to initiate confinement without operator intervention. Personnel exposure dose rates should only be measured with an ion-chamber or equivalent type monitor. A survey meter should be used only for detection of contammation.

3.4 Limitations on Exneriments 3.4.1 Approval and Conductof Experiments Applicability This specification applies to all experiments involving the reactor.

Prior to performing any experiment, the proposed experiment or class of experiments shall be approved as provided in Section 6.4.

b.

All experiments shall be carried out in accordance with established and approved written procedures. Minor changes to written procedures that do not significantly alter the experiment may be made by a Class A Operator provided these changes are documented.

3.4.2 Reactivity.

~

Applicability This specification applies to the reactivity associated with experiments.

Objective June 1986 edition

Reed Reactor Facility Technical Specifications Page 21 The objective is to control the amount of reactivity associated with experiments to values that will prevent the reactor safety limit from being exceeded.

Specification (s)

The reactor shall not be operated unless the following conditions goveming experiment reactivity exist:

a.

Any movable experiment shall have a reactivity worth less than 0.75% Ak/k ($1.00).

b.

Any secured experiment shall have a reactivity worth less than 1.01% Ak/k ($1.35).

c.

d.

No experiment shall be performed if failure of such experiment could lead to a failure of a fuel element or of other expenments and these associated failures could result in a measurable increase in reactivity or a i

measurable release of radioactivity.

Basis a.

The worth of a single movable experiment is limited so that sudden removal movement of the experiment will not cause prompt criticality. The limited worth of a single movable experiment will not allow a reactivity insertion that would exceed the reactor safety limit.

b.

The maximum worth of a secured experiment is limited so that the reactor safety limit will not be exce:ded by removal of the experiment. Since these experiments are secured in place, removal from the reactor operating at full power would result in a relatively slow power increase such that the reactor protective systems would act to prevent excessive power levels from being attained.

c.

The maximum worth of experiments is limited so that removal of the total worth of all experiments will not exceed the reactor safety limit.

d.

The interaction of all experiments in the reactor is to be considered to assure the safety of the reactor under all anticipated operating condidons.
