Sentences with phrase «of fuel rods»

A nuclear reactor generates power from a cluster of fuel rods inside its core, each filled with uranium oxide.

This would also avoid the meltdown of the fuel rods.

One - quarter of the fuel rods were removed to render the core incapable of sustaining a chain reaction.

If the suppression pool is damaged or cracked and can no longer help cool the reactor — and 2.7 meters of the fuel rods in that reactor remain exposed, according to Tokyo Electric Power Company — radioactive material might escape.

It will take a complex engineering effort to deal with thousands of fuel rods, along with the mangled debris of the reactors and the water used to cool them.

The National Research Council report said that as pool water levels drops, through a leak or other causes, temperatures of the fuel rods increase, accelerating oxidation of the cladding and the production of hydrogen gas.

The report calls for a long - term spent fuel U.S. repository but says the country can get by for the short term with interim storage of fuel rods at plants or other facilities.

Once the reactor's control rods are between sections of fuel rods, how is fission slowed to where it is controllable?

That could allow reactor operators to squeeze extra energy out of fuel rods before refueling: The rods are typically replaced after four or five years in a reactor, and degradation of the cladding is a major limitation on their longevity.

The buildings housing reactors Nos. 1, 2, 3 and 4 have all suffered damage from hydrogen explosions, caused by the high - temperature, high - speed interaction of fuel rods and steam.

The pool held the entire complement of fuel rods from the reactor's core, which had been emptied 3 months before the 11 March earthquake and tsunami struck.

The next step is fabrication of the skeleton, a structure formed by rods, nozzles and grids and which, after inspection, will serve as the support for insertion of the fuel rods.
