WebD2O exhibits about 2600 times neutron-moderating ability compared to H2O. This has contributed to the revolution in nuclear power production as D2O provided an optimized source as a moderator in pressurized heavy water reactor (PHWR). WebYes , D2O is more polar than H2O , due to that Deutirium is more electronegative than hydrogen, so the dipole moment of D2O will be more because of increasing in the difference in...
