The manual scram allows the operator to shut down the system at any time if an unsafe or abnormal condition occurs. In the event of failure of the power supply for the safety channels, operation of the reactor without adequate instrumentation is prevented. The preset pulse timer ensures that the reactor power level will return to a low level after pulsing. The emergency stop allows personnel trapped in a potentially hazardous exposure room, or the reactor operator, to scram the reactor through the facility interlock system. The pool water level ensures that a loss of biological shielding would result in a reactor scram. The watchdog scram ensures reliable communication between the User Interface Terminal (UIT) and the Console Computer System (CCS).
The AC power loss scram ensures that a loss of AC power to the uninterruptible power supply (UPS) for the reactor control console will result in a scram.

Table 3. Minimum Reactor Safety System Interlocks Effective Mode Action Prevented Steady State Pulse Pulse initiation at power levels greater than 1 kW X Withdrawal of any control rod except transient X Any rod withdrawal with power level below 1 x 10-5 watts as measured by the Linear Power Channel (NMP-1100) X X Simultaneous manual withdrawal of two standard rods X Any rod withdrawal if high voltage is lost to the Log Power Channel (NLW-1000) X X Withdrawal of any control rod if reactor period is less than 3 seconds X Application of air if the transient rod drive is not fully down. This interlock is not required in square wave mode. X
- Reactor safety system interlocks shall be tested daily whenever operations involving these functions are planned Bases The interlock preventing the initiation of a pulse at a power level above 1 kW ensures that the pulse magnitude will not allow the fuel element temperature to exceed the safety limit. The interlock that prevents movement of standard control rods in pulse mode will prevent the inadvertent increase in steady state reactor power prior to initiation of a pulse. Requiring a minimum power level to be measured by the Linear Power Channel ensures sufficient source neutrons to bring the reactor critical under controlled conditions. The interlock that prevents the simultaneous manual withdrawal of two standard control rods limits the amount of reactivity added per unit time. Correct high voltage to the Log Power Channel ensures accurate power indications. Preventing the withdrawal of any control rod if the period is less than 3 seconds minimizes the possibility of exceeding the maximum permissible power level or the fuel temperature safety limit.

4.2.2. REACTOR SAFETY SYSTEMS Applicability These specifications apply to the surveillance requirements for measurement, test, and calibration of the reactor safety systems.
Objective The objective is to verify the performance and operability of the systems and components that are directly related to reactor safety.
Specifications
- a. A channel test of the scram function of the high-flux safety channels shall be made each day that reactor operations are planned.
- b. A channel test of each of the reactor safety system channels in Table 2 and Table 3 with the exception of the exposure room emergency stop and AC power loss scrams for the intended mode of operation shall be performed weekly, whenever operations are planned.
- c. Channel calibration, including verification of the setpoints for the high voltage loss to safety channel scrams, shall be made of the NP, NPP, NLW, NMP or any other console instrumentation designated to provide direct power level information to the operator, annually not to exceed 15 months.
- d. A thermal power calibration shall be completed annually not to exceed 15 months.
- e. The exposure room emergency stop and AC Power Loss scrams shall be tested annually, not to exceed 15 months.
- f. The low pool water scram shall be tested weekly not to exceed 10 days whenever operations are planned.
- g. The console manual scram button shall be tested weekly not to exceed 10 days whenever operations are planned.
Bases TRIGA system components have proven operational reliability. Daily tests ensure reliable scram functions and ensure the detection of channel drift or other possible deterioration of operating characteristics. The channel checks ensure that the safety system channel scrams are operable on a daily basis or prior to an extended run. The power level channel calibration will ensure that the reactor is operated within the authorized power levels.

4.2.4. FACILITY INTERLOCK SYSTEM Applicability This specification applies to the surveillance requirements that ensure the integrity of the facility interlock system.
Objective The objective is to ensure performance and operability of the facility interlock system.
Specifications Functional checks shall be made annually, not to exceed 15 months, to ensure the following:
- a. With the lead shield doors open, neither exposure room plug door can be electrically opened.
- b. The core dolly cannot be moved in region 2 with the lead shield doors closed except during the use of the core dolly interlock override switch.
- c. The lead shield doors cannot be opened to allow movement into the exposure room projection unless a warning horn has sounded in that exposure room, or unless two licensed reactor operators have visually inspected the room to ensure that no personnel remain in the room prior to securing the plug door.
Bases These functional checks will verify operation of the interlock system.
Experience at AFRRI indicates that this is adequate to ensure operability.
