Dec 07, 2020 - Science & Technology: Nuclear Technology Notes | EduRev is made by best teachers of UPSC. A heavy-water SCWR could breed fuel from thorium (4x more abundant than uranium), with increased proliferation resistance over plutonium breeders. 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. 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. The AHWRs are expected to shorten the period of reaching the stage of large-scale thorium utilization. Concurrently, it is proposed to use thorium-based fuel, along with a small feed of plutonium-based fuel in Advanced Heavy Water Reactors (AHWRs). 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. Stage III, Stage II, Stage I. Heavy water as moderator . 2. The Stage II Fast Breeder Reactors are designed to “breed” more fuel than they consume. Jaitapur 1&2. Explained: The significance of Kakrapar-3. Development of thorium-plutonium (Th-Pu) and thorium-uranium (Th-U233) mixed oxide fuels was initiated in 2001. Heavy water is used as a moderator. … Currently India has 21 reactors that produce 5780 MW, 6 under construction aimed to produce 4300 MW and 33 planned aimed to produce 33000 MW. Heavy water reactors use un-enriched Uranium (U-235) as fuel. Types of Nuclear Reactors: Light Water Reactors (LWR) LWR is a type of Thermal Neutron Reactor. 2 x 1000. Stage III advanced Heavy Water Reactor: would use Thorium-232 and Uranium-233 as fuels. India has vast thorium which would be exploited, using a thermal breeder reactor. The advanced heavy-water reactor (AHWR) is the latest Indian design for a next-generation nuclear reactor that burns thorium in its fuel core.

Which of the following statements are correct about AHWR? • 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. The Atomic Energy Commission was established in 1948 to formulate policies to use nuclear energy in a peaceful manner. 2 x 1650. It is a reactor built for experimentation. Stage 3- Advanced Heavy Water Reactor (AHWR): The main purpose of stage-3 is to achieve a sustainable nuclear fuel cycle. Uses Normal Water instead of Heavy Water as its coolant and Neutron Moderator. Light water as coolant. 4). This reactor has several passive safety systems and runs on coolant flow by … This document is highly rated by UPSC students and has been viewed 2 times. Concurrently, it is proposed to use thorium-based fuel, along with a small feed of plutonium-based fuel in Advanced Heavy Water Reactors (AHWRs). Currently India's installed capacity of energy is 230,000 MW so nuclear energy could form … In the first stage of the programme, natural uranium fueled pressurized heavy water reactors (PHWR) produce electricity while generating plutonium-239 as by-product. Popular Courses. Kovvada, Andhra Pradesh. Hence Statement 1 is correct. KAMINI Reactor – It is currently the only reactor in the world operating on U-233 fuel. The Department of Atomic Energy (DAE) was established in 1954 AD to execute these policies. Stage II, Stage I, Stage III. It uses heavy water (Deuterium oxide D2O) as its coolant and moderator. • Fuelled by thorium and using light water … The first Pressurised Heavy Water Reactor (PHWR) of 220 MWe was commissioned on May 6, 1993, while the second unit of similar capacity was commissioned on September 1, 1995. Example: Fukushima Daiichi, Japan. AHWR300-LEU is a 300 MWe, vertical, pressure tube type, boiling light water cooled, and heavy water moderated reactor. Heavy water reactors: These reactors uses heavy water i.e. Pressurized Heavy-Water Reactor (PHWR) Uses heavy water (deuterium oxide D2O) as its coolant and neutron moderator.
