It is now known that virtually none of the neutron absorbers reached the core.

Xenon-135, an important neutron absorber, makes solid fueled reactors difficult to control.

Also, it is used as a neutron absorber in control rods for nuclear power reactors.

Xenon-135 is the most powerful known neutron absorber.

On the other hand, a neutron absorber will decrease the reactivity of a nuclear reactor.

Liquid neutron absorbers are also used in rapid shutdown systems for light water reactors.

Control can also be attained by adding pebbles containing neutron absorbers.

Dissolved in water, it acts as a neutron absorber in nuclear power plants.

The somewhat different energy absorption regions of the materials make the alloy an excellent neutron absorber.

Iodine-135 itself is a weak neutron absorber.

Many of these are neutron absorbers, called neutron poisons in this context.

In its elemental form, samarium is used in the nuclear industry as a neutron absorber.

Heavy water is employed in nuclear reactors because it is a weaker neutron absorber.

Boron is another common neutron absorber.

Lithium-6 is valued as a source material for tritium production and as a neutron absorber in nuclear fusion.

Another isotope, samarium-149, is a strong neutron absorber and is therefore added to the control rods of nuclear reactors.

The fuel channels may instead of fuel contain fixed neutron absorbers, or be empty and just filled with the cooling water.

Neutron absorber in nuclear reactors.

If a neutron absorber, or neutron poison, is injected at any time during this period, the reactor will shut down.

The small diameter polyethylene spheres are surrounded by layers of neutron absorbers with suitable composition and thickness.

Some rare earth elements are excellent neutron absorbers and are less rare than silver (reserves of about 500,000t).

Light water (the ordinary HO) is both a neutron moderator and a neutron absorber.

Burnable neutron absorbers within the fuel and control rod inventory are used to suppress hot excess reactivity.

By quizzing them about impurities in their graphite, he found that it contained boron, a neutron absorber.

They may be reduced by capturing long isotope rows of the same element or by not using neutron absorbers for trimming.
