Uses Normal Water instead of Heavy Water as its coolant and Neutron Moderator. Pressurized Heavy-Water Reactor (PHWR) Uses heavy water (deuterium oxide D2O) as its coolant and neutron moderator. The first two stages, natural uranium-fueled heavy water reactors and plutonium-fueled fast breeder reactors, are intended to generate sufficient fissile material from India's limited uranium resources, so that all its vast thorium reserves can be fully utilised in the third stage of thermal breeder reactors. -> Click Here. Types of nuclear reactors: fast breeder reactor, boiling water reactor, pressurised water reactor (PWR), Pressurized heavy water reactor (PHWR), advanced heavy water reactor (AHWR) Major nuclear projects in India- which technology to be used, which foreign countries and companies have helped them – memorisation technique. Until now, the biggest reactor size of the indigenous design was the 540 MWe, two of which have been deployed in Tarapur, Maharashtra. Obstacles in the deployment of Thorium based reactors. Kudankulam 3&4. Concurrently, it is proposed to use thorium-based fuel, along with a small feed of plutonium-based fuel in Advanced Heavy Water Reactors (AHWRs). 2. A fast SCWR could be a breeder reactor, like the proposed Clean And Environmentally Safe Advanced Reactor. Jaitapur 1&2. Some of the uses of Thorium are mentioned below. The ongoing development of 300 MWe advanced heavy water reactor (AHWR) at BARC aims at developing expertise for thorium utilization and demonstrating advanced safety concepts. Which of the following statements are correct about AHWR? The third unit at Kakrapar achieved … Policies: India’s Nuclear Doctrine: Google it please Institutions: I think I already mentioned them above. Deuterium oxide (D2O) as its coolant and moderator. Currently India's installed capacity of energy is 230,000 MW so nuclear energy could form … Advanced Heavy Water Reactor • As a part of this programme, BARC has been developing a 300 MWe Advanced Heavy Water Reactor (AHWR). Objective of 3 Stage program: AHWR300-LEU is a 300 MWe, vertical, pressure tube type, boiling light water cooled, and heavy water moderated reactor. Development of thorium-plutonium (Th-Pu) and thorium-uranium (Th-U233) mixed oxide fuels was initiated in 2001. LWR (Light Water Reactors) - enriched Uranium based fuel - imported. Uses of Thorium. This reactor has several passive safety systems and runs on coolant flow by … Kovvada, Andhra Pradesh. Popular Courses. For Previous Static Quiz (ARCHIVES) – CLICK HERE . OGP InstaClasses- Classroom Program - 2021 (Online) OGP InstaClasses - Classroom Program - 2021 (Offline - Bangalore) Integrated Prelims cum Mains (IPM) Program - 2021; … [5,6] Current State. Kovvada, 1&2. 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. … Thorium-232 is a fertile material and not … The family of the Department of Atomic Energy has five research centers. A heavy-water SCWR could breed fuel from thorium (4x more abundant than uranium), with increased proliferation resistance over plutonium breeders. 2018 is now the target date. Stage III Advanced Heavy Water Reactor: would use Thorium-232 and Uranium-233 as fuels. The AHWRs are expected to shorten the period of reaching the stage of large-scale thorium utilization. KAMINI (Kalpakkam Mini reactor) was the first reactor in the world designed specifically to use uranium-233 fuel. Chhaya Mithi Virdi, 1&2. KAMINI Reactor – It is currently the only reactor in the world operating on U-233 fuel. The advance nuclear system would be used a combination of Uranium-233 and Thorium. LEU is readily available in the world market which can be utilised in the AHWR reactor. It will act as a demonstration reactor … India’s Nuclear Tests: 1974 and 1998. Stage III advanced Heavy Water Reactor: would use Thorium-232 and Uranium-233 as fuels. Hence Statement 1 is correct. It is a Plutonium based reactor with high efficiency. We note here that the PHWRs were chosen for the first stage because in 1960s, India had the efficient reactor design in terms of uranium utilisation. Stage II, Stage III, Stage I. Stage II, Stage I, Stage III. Heavy water as moderator . Pressurized Heavy Water Reactor (PHWR) Fast Breeder Reactor (FBR) Advanced Heavy Water Reactor (AHWR) Stag-1 (PHWR) The first stage involved using natural uranium to fuel PHWR to produce electricity and producing Plutonium-239 as a by-product. Reactors with International Co-operation. Example: Fukushima Daiichi, Japan. Insights has redefined the way preparation is done in UPSC civil service exam. Thorium based system such as AHWR can be set up on commercial scale only after a large capacity based on fast breeder reactors, is built up. This document is highly rated by UPSC students and has been viewed 2 times. The BWR drives the steam turbine when the reactor core heats the water converting it into steam. Chhaya Mithi … 2 x 1650. This research included the development of indigenous equipment for the production of thorium dioxide powder and trials with uranium dioxide. Setting up Pu-239 fuelled fast Breeder Reactor of 500 MWe power generation is in advanced stage of completion. • Advanced Heavy Water Reactor(AHWR) The first stage involved using natural uranium to fuel PHWR to produce electricity and producing Plutonium -239 as a byproduct.
