Light Water Reactor - Reactor Design - Fuel
... water makes it necessary to do a certain amount of enrichment of the uranium fuel before the necessary criticality of the reactor can be maintained ... The light water reactor uses uranium 235 as a fuel, enriched to approximately 3 percent ... Although this is its major fuel, the uranium 238 atoms also contribute to the fission process by converting to plutonium 239 about one-half of which is consumed in the reactor ...
Pressurized Water Reactors - PWR Reactor Design - Fuel
... The finished fuel rods are grouped in fuel assemblies, called fuel bundles, that are then used to build the core of the reactor ... A typical PWR has fuel assemblies of 200 to 300 rods each, and a large reactor would have about 150–250 such assemblies with 80–100 tonnes of uranium in all ... Generally, the fuel bundles consist of fuel rods bundled 14 × 14 to 17 × 17 ...

Famous quotes containing the words bundles and/or fuel:

    He bundles every forkful in its place,
    And tags and numbers it for future reference,
    So he can find and easily dislodge it
    In the unloading. Silas does that well.
    He takes it out in bunches like birds’ nests.
    Robert Frost (1874–1963)

    I had an old axe which nobody claimed, with which by spells in winter days, on the sunny side of the house, I played about the stumps which I had got out of my bean-field. As my driver prophesied when I was plowing, they warmed me twice,—once while I was splitting them, and again when they were on the fire, so that no fuel could give out more heat. As for the axe,... if it was dull, it was at least hung true.
    Henry David Thoreau (1817–1862)
