Why Is Stainless Steel So Important in Nuclear Power .

Why Is Stainless Steel So Important in Nuclear Power .

Most reactors contain several steam generators. Moderators – The moderator (graphite or water) sits within the reactor's core and slows fission-produced neutrons. Rods – Created to control or curtail nuclear reactions, control rods reside in the reactor core. They contain boron, cadmium, or hafnium—all of which absorb neutrons effectively.

4 Types of Nuclear Reactors Used in Power Generation .

Atomic piles or nuclear reactors. The number of neutrons resulting from a single fission is known as the multiplication factor. When this is less than 1 a chain reaction is impossible; when greater than 1 a chain reaction might take place. In an atomic pile, or a nuclear reactor, fissionable material is so arranged that the multiplication factor can be carefully controlled.

Heat Exchanger Flow: Cross flow, Parallel flow, Counter .

A heat exchanger can have several different flow patterns. Crossflow, parallel flow, and counterflow heat exchanger configurations are three examples. A counterflow heat exchanger will require less heat exchange surface area than a parallel flow heat exchanger for the same heat transfer rate and the same inlet and outlet temperatures for the fluids.

The classic example of a heat exchanger is found in an internal combustion engine in which an engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. In power engineering, common applications of heat exchangers include steam generators, fan coolers, cooling water heat exchangers, and condensers.
