Reactor PLC

Reactor Programmable Logic Controller

Unlike the RTUs, this device both provides an interface to a peripheral (the reactor) to the supervisor, but also takes actions on its own. This application offers:

• The Reactor Protection System (RPS)
• Communications interface with the supervisor for manual and automatic control and reporting of build and status information
• Burn rate setpoint ramping
• Crash-resilient "threaded" application

Reactor Protection System

The RPS checks for unsafe conditions and then SCRAMs the reactor if those conditions are met. Even if someone tries to re-enable the reactor through the Mekanism interface, it will re-SCRAM the reactor until it is RESET.

RPS SCRAM Conditions

• Critical/High Reactor Damage
• High Core Temperature
• Low Coolant
• Excess Waste
• Excess Heated Coolant
• No Fuel
• PPM Fault
• Supervisor Connection Timeout (if in networked mode)
• Manual SCRAM via Supervisor (if in networked mode)
• Automatic SCRAM via Supervisor (if in networked mode)
• PLC System Failure (reactor not formed)
• Force Disabled (reactor force disabled by Mekanism itself due to having "melted down" on a server with meltdowns disabled)
