Solution

Dear Student,

Heavy water is used in certain types of 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.
