Heavy water(PHWR)--Pressurised heavy water reactor
Most often, light water (H2O) is used as a moderator in a nuclear reactor. Sometimes, heavy water (D2O), or graphite is used.
CANDU, a reactor type designed in Canada which uses heavy water as the primary coolant.
Heavy water
The used fuel in a nuclear power plant is the nuclear fuel being discharged from the nuclear reactor after being irradiated during reactor operation. It is usually composed of trans-uranium heavy elements, a wide variety of fission products (that resulted from the nuclear fission processes in the nuclear reactor) and products of radioactive decay (produced before and after fuel discharge from the nuclear reactor).
It is a process, in which a heavy nucleus is broken down in to two or more medium heavy fragments. It is used in nuclear reactor and atom bomb.
The moderator used in nuclear reactors with natural uranium is generally the heavy water (D2O).
Water (H2), or heavy water (D2O). Sometimes, liquid sodium is used.
No people are not allowed to leave North Korea, they can escape to South Korea, but risk being shot, or if caught trying to escape North Korea they can get heavy punishment, so the only way to get out of North Korea if your North Korean is to escape out of North Korea secretly, and go to South Korea, via another country that can give you asylum.

Different types of nuclear plants: Pressurised Water Reactor (PWR); Boiling Water Reactor (BWR); Heavy Water Moderated Reactor (CANDU); Advanced Gascooled Reactor (AGR); Fast Breeder Reactor (FBR); Pebble Bed Gascooled Reactor; Water Cooled Graphite Reactor (RBMK). There are other ideas that only exist on paper.
Heavy water (deuterium) functions as a moderator. It slows down fast neutrons released by fission reactions in order to allow the reaction to be sustained. Fast neutrons pass through the reactor before initiating another fission reaction.
