2.0 SAFETY LIMITS AND LIMITING SAFETY SYSTEM SETTINGS

^

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'wer shall not exceed 250 kilowatts. However, for the

, 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 A

than 30 psi. Section 7.1 of the SAR gives a maximum measured fuel temperature 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 c SAR and in papers available as " Fuel Elements for Pulsed TRIGA Research Reactors", Simnad, er al., Nuclear Technology,2.1, 31 (January,1976), and "The ,

U-ZrH xAlloy: . Its Properties and Use'in TRIGA Fuel", GA Project No. 4314 Report E-117-833, General Atomic Company, P.O. Box 81608, San Diego, CA 92138,1980.

Specifigations(s)

- Maximum excess reactivity shall be 2.25% Ak/k ($3.00) with experiments in Pl ace. ,.

~

. Basis ,

Maximum excess cose reactivity is sufficient to provide the core rated power, xenon compensation, and reactivity for shutdown. Analysis of the reactor core demonstrates that no single pomponent represents sufficient potential reactivity to reach tiie reactor safety limit during any condition of operation. (SAR Sections 2.2 Reactivity Insertion and 7.1 Reactor Power Transients)

~ '

3.1.2 Shutdown Margin. '

, Applicability This speification applies to the reactivity margin by which the reactor core will.be contricered shutdown.

Objective

~

The objective is 'to ass'ure that the reactor can be shut down safely by a margin that is sufficient to compensdte for the failure of a control rod or the movement of an experiment. . ...

Specification (s) .

c.- The highest worth, movable experiment in its most reactive sta'te.

.. e June 1986 edition . ,

  • e
  • _O

Reed Reactor Facility Technical Specifications Page 14 .

Basis

' 'Ihe value of the shutdown margin assures that the reactor can be shut down from any operating condition even if the highest worth contml rod should remain in the fully withdrawn position and a movable experiment is in a high reactivity state.

3.1.3. FuelElements -

Applicability" This specification applies to the fuel elements.

Objective

. The objective is to ensure the physicalintegrity of the fuel element cladding.

~

Specification (s) ,.

c. Upon detection of elevated radioactivity levels by the Continuous 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.

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.

b. Any secured experiment shall have a reactivity worth less than

, 1.01% Ak/k ($1.35).

c. The total reactivity worth ofin-core experiments shall not exceed 1.50% Ak/k ($2.00). This shallinclude the potential reactivity which might result from malfunction, flooding, voiding, or removal and insertion of the experiments.

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.
