1.	In which reactor is the coolant in direct contact with the heat producing nuclear fuel?(a) Fast breeder reactor(b) Pressurized water reactor(c) Boiling water reactor(d) Heavy water reactorThis question was posed to me in final exam.My doubt is from Types of Nuclear Reactor & Nuclear Waste in chapter Nuclear Power Plant of Energy Engineering
Answer» Right answer is (c) Boiling water reactor To ELABORATE: In boiling water reactor, the coolant is in direct contact with the heat PRODUCING NUCLEAR fuel and boils in the same compartment in which the fuel is located. The reactor pressure is maintained at 70bar. The coolant THUS SERVES the triple function of coolant, moderato and working fluid.
