How do you control a nuclear reaction? | Questions | Naked .

Jul 18, 2010 · Chris - They use what are called control rods - these are dense materials which, when dropped down into the reactor, soak up some of the neutrons that are produced by the nuclear chain reaction. The consequence of that is that there are fewer neutrons left to bust open other uranium or fissionable nuclei, and as a result, the chain reaction is slowed down.

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.

Elements of Chemical Reaction Engineering

The tubular reactor (i.e., plug-flow reactor [PFR]) is relatively easy to maintain (no moving parts), and it usually produces the highest conversion per reactor volume of any of the flow reactors. The disadvantage of the tubular reactor is that it is difficult to control temperature within the reactor, and hot spots can occur when the reaction .

PID Controller: Types, What It Is & How It Works | Omega

A PID controller is an instrument used in industrial control applications to regulate temperature, flow, pressure, speed and other process variables. PID, which stands for proportional integral derivative, controllers use a control loop feedback mechanism to control process variables and are the most accurate and stable controller.

Autoclave (industrial) - Wikipedia

An autoclave applies both heat and pressure to the workload placed inside of it. Typically, there are two classes of autoclave. Those pressurized with steam process workloads which can withstand exposure to water, while circulating heated gas provides greater flexibility and control of the heating atmosphere.. Processing by autoclave is far more costly than oven heating and is therefore .

Temperature Controller Basics Handbook | Instrumart

Temperature controllers are used in a wide variety of industries to manage manufacturing processes or operations. Some common uses for temperature controllers in industry include plastic extrusion and injection molding machines, thermo-forming machines, packaging machines, food processing, food storage, and blood banks.
