These principal components are interconnected by the reactor coolant piping to form a loop configuration. Outside of reactor physics, heavy water is used in chemistry to help identify the structures of compounds and in biology for studies of metabolism.
Pressurized heavy water reactors are a subset of pressurized water reactors, sharing the use of a pressurized, isolated heat transport loop, but using heavy water as coolant and moderator for the greater neutron economies it offers. The lack of enrichment facilities necessita ted the use of natural uranium.

Boiling water reactor (BWR) BWRs are characterized by boiling water around the fuel rods in the lower portion of a primary reactor pressure vessel. This publication presents a comprehensive summary of the technical work carried out under an IAEA coordinated research project (CRP) and provides an overview of Member States' approaches to mitigate challenges that are encountered in achieving reliability, sustainability and safety with advanced pressurized heavy water reactor (PHWR) fuels.
This high pressure is maintained by Pressurized Water Reactor (PWR): It is a thermal reactor, using enriched uranium oxide, clad in zircalloy as fuel. Cheng Brookhaven National Laboratory R. Wigeland Idaho Natioanl Laboratory C. Bathke, C. Murphy, B. Boyer, J. Doyle, B. Fane Los Alamos National Laboratory B. Ebbinghaus Lawrence Livermore National Laboratory August 2012 Nuclear Science and Technology Department … They are cooled and moderated by high-pressure liquid water (e.g. The reactor coolant system of the pressurized water reactor (PWR) consists of a reactor vessel, steam generators, reactor coolant pumps, a pressurizer, and other elements. Instead of using a single large reactor vessel as in a PWR or BWR, the nuclear core is contained in hundreds of pressure tubes. heavy water, a material of concern with regards to proliferation since use in reactors will allow production of weapons-grade plutonium from natural uranium. At this pressure water boils at approximately 350°C (662°F). Description .

If a heavy water reactor has had leakages from the primary system tritium may be found in the concrete of the biological shield, necessitating removal or immobilization. If the material is considered for clearance it is necessary to document that the contents of tritium in the solid material is below clearance levels. The Indian Advanced Heavy Water Reactor (AHWR) and Non-Proliferation Attributes M. Todosow, A. Aronson, L.-Y. Instead of using a single large reactor vessel as in a PWR or BWR, the … Nuclear Power-> Nuclear Power Plant-> Types of Reactors-> CANDU - Heavy water reactor. A pressurized heavy-water reactor (PHWR) is a nuclear reactor, commonly using unenriched natural uranium as its fuel, that uses heavy water (deuterium oxide D 2 O) as its coolant and neutron moderator.The heavy water coolant is kept under pressure, allowing it to be heated to higher temperatures without boiling, much as in a pressurized water reactor.
