mcqs about candu reactor
A nuclear reactor is a device in which nuclear chain reactions are initiated, controlled and sustained at steady rate. IF YOU THINK THAT ABOVE POSTED MCQ IS WRONG. The light water reactors are of two types viz. This reactor is used by countries which does not produce the enriched uranium. What is a nuclear reactor? a. Mainly, because of it's natural properties, reactors can be … CANDU in Context – September 2014 PROLOGUE CANDU in Context prepared by Dr. William J. Garland, Professor Emeritus, Department of Engineering Physics, McMaster University, Hamilton, Ontario, Canada Summary: Herein, we introduce the CANDU reactor by first looking at the broad social context to see why we need nuclear power. c. Plot qualitatively the reactor power variation over time d) Discuss the importance of delayed neutrons in nuclear reactors. The heat is absorbed by the boiler water, which turns to steam in the secondary loop. Signaling its intent to fast-track India’s domestic nuclear power programme, the government on Wednesday approved a proposal to construct 10 indigenous units of pressurised heavy water reactors (PHWRs), each with the capacity of generating 700 Mega Watt (MW) of electricity, in a fully home grown initiative. CGE had developed this design on the basis of its earlier work in the design of NPD. It is primarily concerned with the arrangement of electrons around The total quality of run off during that period c. Total power available d. Total storage of the plant ANSWER: b. 93. © Copyright 2016-2020 - www.PakMcqs.com/. - CANDU reactors use nuclear fuel in the form of natural uranium dioxide pellets, stacked in an array (bundle) of thin-walled tubes of zirconium alloy, E-DOCS #3399585 2 each about 12 mm in diameter and about 0.5 m in length, and called . The CANDU reactor has a design flaw that makes it subject to potentially catastrophic LOCAs with little or no warning – at least under the present inspection procedures and practices. : 141 The KANUPP-1 uses the water-cooled Deuterium oxide (D 2 O or heavy water) moderator with natural uranium serving it as its fuel. CANDU reactor. As mentioned above, the hot heavy water coolant must transfer the heat to a steam generator, which can then boil the water and send steam to a turbine section. 67. A CANDU reactor uses _____. In the end, your results will be displayed on the spot. MCQ - 04. The reason that a steam generator is used is due to the fact that the heavy water coolant is radioactive from being in direct contact with the reactor core. ANSWER: c. Uranium, to absorb the neutrons from the fissile material and gets converted into fissile material. Breeder reactor. The cumulative defect rate for CANDU fuel is 0.1%, with the current rate running below 0.05% (1). In operating inherently hazardous technologies like CANDU nuclear reactors, we must anticipate safety-critical component failures rather than idly waiting for them to occur. ANSWER: d. Both (a) and (c).Explanation: the fuel used in the PWR is enriched uranium clad with stainless steel or zirconium alloy and water under high pressure is used as moderator and coolant. Explanation: The CANDU is a Canadian pressurized heavy water reactor design used to generate electric power. 1.A thermal reactor needs a moderator material 2. About: The Kaiga Atomic Power Station (KAPS) is a nuclear power generating station situated at Kaiga, near the river Kali, in Uttar Kannada district of Karnataka, India. The CANDU And PHWR Reactors The CANDU (Canada Deuterium Uranium) reactor was developed in the 1950s in Canada, and more recently in India as the PHWR (Pressurized Heavy Water Reactor). Natural uranium fuelled heavy water cooled & moderated B.

Sep 04, 2020 nuclear reactor engineering reactor systems engineering 4th edition vol 2 Posted By Astrid LindgrenMedia Publishing TEXT ID 6737c77c Online PDF Ebook Epub Library Amazon Nuclear Reactor Engineering Reactor Systems Heavy water is used both as coolant and moderator. Reasons for the choice of key parameters are given. 0. Reactor Generations Gen I Prototypes in 50s & 60s. Which reactor uses heavy water as moderator ? Despite its smaller size, the Pickering station powers up to 2.5 million households. Natural uranium fuelled heavy water cooled & moderated It combines features of the existing CANDU pressurised heavy water reactors (PHWR) with features of light-water cooled pressurized water reactors (PWR). Similarly, the government's promised $75 million to complete development of a next-generation Candu reactor — called the Enhanced Candu 6 - may not be the last public cash into that project.
