page 2 Movable Exoeriment An experiment is movable when it is intended that all or part of the experiment may be moved in or near the core or into and out of the reactor while the reactor

-is operating.

Operable Operable means a component or system is capable of performing its intended function. -

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

Pulse Mode The reactoris in the pulse mode when the reactor mode selection switch is in the pulse position. In this mode, reactor power may be increased on periods less than one second by motion of the transient control rod.

Reactivity Worth of an Exoeriment The reactivity worth of an experiment is the maximum value of the reactivity change that would occur as a iesult of planned changes or credible

, malfunctions that alter experiment position or configuration.

Reactor Committee The group of persons at the University who are assigned responsibility for review and audit of facility operation and review of changes and experiments in accordance with 10 CFR 50.59.

Reactor Ooerating . The reactor is operating whenever it is not secured or shutdown.

Reactor Safety Svstems . Reactor Safety Systems are those systems, including associated

- input chonnels, which are designed to initiate automatic reactor protection or to provide information for initiation of manual protective action.

Reactor Secured . The reactor is secured when:

a. it contains insufficient fissile material or moderator present in the reactor, adjacent experiments or control rods, to attain criticality under optimum available conditions of moderation and reflection, or
b. fl. The minimum number of neutron absort>ing control rods are fully inserted or

. other safety devices are in shutdown position, as required by technical specifications, and

2. The console key switch is in the off position and the key is removed from the lock, and

Reactor Shutdown The reactor is in a shutdown condition when sufficient control rods are inserted to assure that itis subcritical by at least $1.00 of reactivity.

Reportable Occurrence . A Reportable (kmrrence is any of the following which occurs

during reactor operation
-
a. l Operation with actual safety system settings for required systems less conservative
f. ;than the limiting safety system settings specified in Technical Specification 2.2.
bD Operation in violation of hmeting conditions for operation established in the Technical

Control Rod . A control rod is a device fabricated from neutron absorbing material or fuel

& which is used to establish neutron flux changes and to compensate for routine reactivity

@ losses. A control rod may be coupled to its drive 'unit aliowing it to perform a safety function

Transient Rod . The transient rod is a control rod with scram capabilities that is capable of

. Applicabildy

Objective

. L The objective is to define a power level below which it can be predicted with confidence

~

that no damage to the fuel elements will occur. - '

Specincation . _

7 The power level of the reactor in the steady. state mode shall not exceed 1000 kW under any conditions of operation.

Basis L  : It has been shown by expensive experience that operation of TRIGA reactors at a power

!-  : level of .1000 kW will not result in damage to the fuel. Reactors of this type have -

t ) operated successfully for decades at power levels in the range from 1000 to 1500 kW

- and above. The criterion for assuring the liitegrity of a TRIGA fuel element is that the I fuel temperature be maintained below 1000*C. It has been shown by analysis and by

i. & ' measurements on other TRIGA reactors that a power level of 1000 kW corresponds to a L . peak fuel temperature of approximately 400*C. Thus, a Safety Limit on power level of L- (1000 kW pmvides an ample margin of safety for operation.

page 36 6.8 Review of Experiments

- a. All proposed new experiments utilizing the reactor shall be evaluated by the

. experimenter and the Reactor Committee. The evaluadon shall be reviewed by a licensed Senior Operator of the facility (and the Health Physicist when appropriate) to assure compliance with the provisions of the utilization license, the Technical

- Specifications,10 CFR 20, and the requirements of 10 CFR 50.59. If, in his judgment, the experiment meets with the above provisions and does not constitute a threat to the integrity of the reactor, he shall submit it to the Reactor Supervisor for scheduling or to the Reactor Committee.for final approval as indicated in Section 6.2 above. When pertinent, the evaluation shallinclude:

1. The reactivity worth of the experiment;
2. . The integrity of the experiment, including the effects of changes in temperature, pressure, or chemical composition;
3. Any physical or chemicalinteraction that could occur with the reactor n components; and
4. Any radiation hazard that may resuit from the activation of materials or from extemal beams.
5. A determination that for the maximum planned or inadvertent pulse, no credible mechanism exists which could cause the experiment to fail.
b. Prior to performing an experiment not previously performed in the reactor, it shall be reviewed and approved in writing by the Reactor Committee. This review shall consider the following information:
1. The purpose of the experiment;
2. A procedure for the performance of the experiment; and
3. The evaluation approved by a licensed Senior Operator.
c. For the irradiation of materials, the appl 5nt shall submit an " Irradiation Request" to

- the Reactor Supervisor. This request shall contain information on the target material including the amount, chemical form, and packaging. For routine irradiations (which do not contain known explosive materials and which do not constitute a significant threat to the integrity of the reactor or to the safety of individuals) the approval for the Reactor Committee may be made by the Reactor Supervisor.-

page 37 J. In evaluating experiments, the following assumptions should be used for the purpose of determining whether failure of the experiment v :uld cause the appropriate limits of 10 CFR 20 to be exceeded:

1. If the possibility exists that airbome concentrations of radioactive gases or aerosols may oe released within the facility,100 percent of the gases or aerosols will escape;
2. If the effluent exhausts through a filterinstallation designed for greater than 99 percent eft.ciency for 0.3 mlcron particles,10% of the particulates will escape; and
3. For a material whose boiling point is above 130*F and where vapors formed by boiling this material could escape only through a column of water above the core,10% of these vapors will escape.
