Er nutzt als Moderator ebenfalls schweres Wasser, aber als Kühlmittel gewöhnliches Wasser (Leichtwasser) und als Brennstoff schwach angereichertes Uran (1 bis 2 % 235 U). Its four CANDU reactors are owned and operated by OPG. Nuclear Reactors MCQs with answers. The total quality of run off during that period c. Total power available d. Total storage of the plant ANSWER: b. In operating inherently hazardous technologies like CANDU nuclear reactors, we must anticipate safety-critical component failures rather than idly waiting for them to occur. 92. A CANDU reactor uses _____. Just like most fossil-fuel power plants, a CANDU system uses turbines to turn turbines, which turn an electric generator; the difference is that CANDUs use nuclear fission to heat the water. Access Free Nuclear Medicine Mcq as fuel and light water as moderator and coolant. 1. 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. 2. 96.
