Temperature Control of Reactors

Tight reactor temperature control enables the optimization of capacity and yield. What happens upfront in the reaction sets the stage for downstream processing and what ultimately ends up in the final product. Generally, increasing reactor temperature will increase reaction rate (capacity) but if the temperature is too high, side reactions may develop reducing reaction selectivity (yield .

Reactor Controller - Feed The Beast Wiki

The Reactor Controller is a block added by the Big Reactors mod. A central command block which has an user interface for the multi-block reactor structure. Every reactor requires a single Controller to function. It may be placed on any of the walls, but not on the edge (outer frame), and neither on the floor nor ceiling of the reactor.

RBMK - Wikipedia

Each of the pressure channels in the core has its own flow control valve so that the temperature distribution in the reactor core can be optimized. Each channel has a ball type flow meter. The nominal coolant flow through the reactor is 46,000–48,000 m 3 /h. The steam flow at full power is 5,440–5,600 t (6,000–6,170 short tons)/h.

Fission Reactor - Official Feed The Beast Wiki

A fission reactor that overheats will undergo a meltdown and random blocks of the structure will melt into radioactive corium. Placed against the controller block, a comparator will emit a signal proportional to the heat level of the reactor, and output a full signal if it exceeds 50% (this can be altered in .

Temperature Control of a Stirred Reactor

Using `K_c`, `tau_I`, and `tau_D` from the IMC tuning correlation, implement a PID controller with anti-reset windup. Test the set point tracking capability of this controller by plotting the response of the process to steps in set point of the reactor temperature (not cooling jacket temperature) from 300K up to 320K and then down to 280K.
