Nuclear fuel - Infogalactic: the planetary knowledge core

Nuclear fuel - Infogalactic: the planetary knowledge core

Nuclear fuel is a material that can be 'burned' by nuclear fission or fusion to derive nuclear energy. Nuclear fuel can refer to the fuel itself, or to physical objects (for example bundles composed of fuel rods) composed of the fuel material, mixed with structural, neutron-moderating, or neutron-reflecting materials.. Most nuclear fuels contain heavy fissile elements that are capable of .

Sep 30, 2011 · The Canadian CANDU reactors don't require enriched fuel, but since they use expensive heavy water instead of ordinary water, their energy cost is about the same. In 1993 there were 109 licensed power reactors in the U.S. and about 400 in the world. They generated about 20 percent of the U.S. electricity.

Methods - Design and Applications of the Nuclear Reactor

A nuclear reactor is a device in which nuclear chain reactions are initiated, controlled, and sustained at a steady rate (as opposed to a nuclear explosion, where the chain reaction occurs in a split second).Nuclear reactors are used for many purposes, but the most significant current uses are for the generation of electrical power and for the production of plutonium for use in nuclear weapons.

May 22, 2020 · CANDU FUEL: CANDU reactors use standard size fuel bundles. Each fuel bundle is about 10.2 cm in outside diameter and is about 0.495 m long. Each fuel bundle consists of 37 to 43 parallel zirconium sheathed tubes on approximately 1.5 cm centers that contain uranium oxide pellets. A CANDU-E6 reactor has 380 pressure tubes also known as fuel channels.
