[2] The heavy water is kept under pressure which increases its boiling point so that it can operate at high temperatures without boiling. 18 July, 2011 : India begins construction of 25th nuclear plant.The first pour of concrete for the 700 MW indigenous Pressurised Heavy Water Reactor (PHWR), the seventh nuclear plant at the Rajasthan Atomic Power Station (RAPS) took place at Rawatbhata. Pressurized Water Reactor (PWR): It is a thermal reactor, using enriched uranium oxide, clad in zircalloy as fuel. Thermal reactors can again have various derivatives, namely Pressurized Water Reactor (PWR), Boiling Water Reactor (BWR), Pressurized Heavy-Water Reactor (PHWR), Advanced Gas Cooled Reactors (AGCR), Light Water Graphite Reactor (LWGR), etc. Outside of reactor physics, heavy water is used in chemistry to help identify the structures of compounds and in biology for studies of metabolism. Construction and working principle of Pressurized Water Reactor (PWR) Pressurized Water Reactor (PWR): Working principle: A nuclear power plant differs from a conventional steam power plant only in the steam generating part. Before starting the reactor, water in pressurizer is boiled and converted into steam by electric heating coil. The below figure shows basic diagram of Pressurized Water Reactor. Pressurized Heavy Water Reactor [PHWR] - Indigenous Indian Design [Nuclear] This progressively maturing Reactor design of the Nuclear Power Corporation of India Ltd. [NPCIL]. Although it comes at an increased price, it doesn't require the uranium fuel to be enriched like in some other nuclear reactors. Mains: Science and technology – developments and their applications and effects in everyday life. This greatly decreases the expense for the heavy water because uranium enrichment requires separate facilities and extensive processes. In an archetypal design of a PWR, as represented in Fig. Pressurized Heavy Water Reactor Fuel: Integrity, Performance and Advanced Concepts Proceedings of the Technical Meetings Held in Bucharest, 24–27 September 2012, and in Mumbai, 8–11April 2013 IAEA TECDOC (CD-ROM) No. In Pressurized Water Reactor (PWR) water or heavy water is used as both coolant as well as moderator. Following are some important features of the Lokpal and Lokayuktas Bill, 2011, passed by Parliament on Jan 18, 2013. Heavy water is still a common moderator in nuclear reactors, most notably in the CANDU reactors and in other pressurized heavy water reactors. Pressurized Water Reactor Power Plant This reactor uses enriched Uranium. 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. Pressurized Heavy Water Reactor (PHWR) A pressurized heavy water reactor (PHWR) is a nuclear power reactor, commonly using unenriched natural uranium … A true companion for knowledge seekers and job hunters..

Operating Principles of a Pressurized Water Reactor. Although the CANDU pressurized heavy water reactor (PHWR) design differs from that of light water reactors (LWRs), many of the materials degradation issues are similar. [2] Deuterium absorbs fewer neutrons than hydrogen , which is extremely important as nuclear fission reactions require neutrons to carry out their chain reactions. Importance of nuclear energy was recognised as soon as India became independent. These reactors, which use natural uranium as fuel and heavy water as both moderator and coolant, offered a basket of options for countries looking for cost-competitive and proven technologies in the small- and medium-sized reactors.
