WebApr 3, 2024 · (i)Deuterium oxide is called heavy water. Heavy water absorbs fewer neutrons than hydrogen, which is extremely important as nuclear fission reactions require neutrons to carry out their chain reactions. (ii)The heavy water is kept under pressure which increases its boiling point so that it can operate at high temperatures without boiling.
WebWhat is heavy water used for? Heavy water is used in certain types of nuclear reactors, where it acts as a neutron moderator to slow down neutrons so that they are more likely to react with the fissile uranium-235 than with uranium-238, which captures neutrons without fissioning. The CANDU reactor uses this design. how fast does frontline workWebFigure 1. A heavy water molecule.
