1.	Select the incorrect statement which supports PWR.(a) Water is used as coolant(b) PWR is stable in operation(c) Uses natural fuel(d) PWR has positive power demand coefficientI have been asked this question in an online quiz.I'd like to ask this question from Types of Nuclear Reactor & Nuclear Waste topic in section Nuclear Power Plant of Energy Engineering
Answer» The correct answer is (c) Uses natural fuel Explanation: PWR uses enriched fuel making the reactor more COMPACT in SIZE. And due to high NEGATIVE temperature coefficient, a PWR is stable. Water is used as the coolant. It does have positive power demand coefficient and RESPONDS greatly to more power demand.
