Figure 6-1: The proposed UFTR Protection System The above system includes the TXS as the primary protection system, providing Monitoring and Indicator System (MIS) and Reactor Trip System (RTS), the T-3000 (with a diverse hardware and software) providing reactor control and a diverse MIS, and a hardwired Manual Reactor Scram (MRS) providing a diverse RTS as compared to TXS.
Further, because of unidirectional communication between the TXS and T-3000, and no communication between the TXS and MRS. The failure of the MRS or T3000 blocks will not impact the operation of the TXS. In summary, as shown in Table 6-1, the above proposed system effectively addresses the functions of the RPS.

The TXS system will process all the signals and according to Section 6.1.2 would determine whether to continue reactor operation or cause a trip that would shut down the reactor.
Reactor power (i.e., core) is monitored by two diverse NI channels, which operate simultaneously for achieving a higher confidence. The reactor is tripped if any one of the NI Channels yields an invalid signal.
In the case of the primary coolant loop, simultaneous monitoring of temperature and flow rate provides further confidence on the safe operation of the core. In the case of the secondary coolant loop, the inlet temperature and flow rate and the outlet temperature are monitored. For the reactor cell, three of the radiation monitors are required and the fourth monitor increases the availability of the reactor.
Finally, the purpose of the monitors of the reactor confinement segment is to monitor the release of radioactivity into the environment.

A trip is initiated whenever any of the following conditions apply.
a) Loss of primary pump power b) Low water level in the core (5 42.5")
c) No outlet flow d) Low inlet water flow (< 41 gpm) 6.2.5.2 Description of Trip Functions a) Loss of primary pump power - AC power for the Reactor Coolant Pump is monitored by Cooling Pump Power Monitor.
Preparedby Reviewed by QA-I, UFTR-QAI-100 UF/NRE Name: Name: Revision 0 Copy I UFTR Date : Initials: Date : Initials: Vol. 1 Page 31 of 81 A relay is utilized to detect pump power status. During normal operation, the relay is energized and the contacts send a binary "1" to the RTS. The RTS recognizes this as an indication of the pump running. If power is lost to the pump, the relay de-energizes and a logic "0" is sent to the RTS. This logic state will initiate the blade-drop trip.
b) Low Water level in the core - The water level in the reactor core is measured by a reactor low level switch. The switch is open when water in the reactor is above the 42.5" setpoint.
This sends a logic value "0" to the TXS. If the water level drops below setpoint, the float switch opens and a logic "0" is sent to the TXS. This logic state will initiate the blade-drop trip.
c) No outlet flow- The reactor outlet flow is monitored by a Primary Flow Switch during normal operation. The flow switch is closed and sends a logic value "I" to the safety computers (indicating normal conditions). If the Primary Flow Switch senses a loss of coolant flow, the switch will open. This produces a logic "0" to the TXS. This logic state will initiate the blade-drop trip.
d) Low Inlet Water Flow - The reactor inlet flow is monitored by the Primary Inlet Flow Sensor This sensor produces an analog signal to the TXS indicating the rate of flow. Should the indicated flow drops below the setpoint, the blade-drop trip is initiated.

These interfaces are made with hardwired contacts or analog signals and data links of various designs. Signals for monitoring/information are also implemented with data links.
The 1/0 shall be isolated to provide protection to the logic voltage level systems and isolate the process devices from the computational devices where possible.
The design of 1/0 interfaces shall accommodate the existing field wiring (i.e., unshielded, not twisted) that may carry elevated induced voltages and current even when field contacts are open (zero (0) condition). Thus a "0" condition may read as a "1" at the 1/0 module interface, thus causing an incorrect UFTR RPS input. To accommodate such a condition, interposing relays (provided by others) are an acceptable means of alleviating unacceptable problems due to 1/0 interfaces.
6.6.7 Failure Handling Analog signals from field sensors that deviate from predetermined parameters shall be alarmed to the QDS/Gateway.
Alarms shall occur on any process input signal fault. This includes signals that are out of range of sensor transmitter output range either high or low.
Alarms shall occur on any communications failure includes:
" Communication failure between TXS and T3000
" Communication failure between TXS and QDS
" Other failures that may be defined later.
6.6.8 Indications All analog signals from field sensors shall be sent to the OAC gateway.
All binary signals from field sensors shall be sent to the OAC gateway.
6.6.9 Alarm, and Annunciation The UFTR RPS shall provide the operator with appropriate and meaningful alarms and annunciations when a reactor condition is reached or as it is approached, dependent on the type and criticality of the process being monitored.
The signals critical to the UFTR operation safety will generate an audible sound to the alarm and annunciation system through the QDS/Gateway for the conditions as set forth in Table 6-3.
When possible, the signal shall be alarmed for the condition as it approaches a trip setpoint to provide the operator with warning of pending conditions. All alarms and annunciations will be ported directly to the QDS and through the Gateway to adjacent support systems (T3000) for alarm and archive.
