Nuclear Reactor Design MCQ — 96 Practice Questions with Answers

Q1. 1. India's Stage-I nuclear power programme envisages natural-uranium, heavy-water moderated and cooled PHWRs. 2. Stage-II envisages Fast Breeder Reactors fuelled by plutonium produced in Stage-I. 3. Stage-III would comprise power reactors using U-233 and thorium as fuel. Which of the statements given above are correct?

Q2. 1. Indigenously built PHWRs form the backbone of the first stage of India's nuclear power programme. 2. Indian PHWRs use domestic natural uranium dioxide with 0.7 percent fissile U-235. 3. Indian PHWRs use heavy water as moderator and primary coolant. 4. Fast Breeder Reactors, not PHWRs, form the backbone of the first stage of India's nuclear power programme. Which of the statements given above are correct?

Q3. Consider the following statements about nuclear reactor design: 1. In a nuclear reactor, fuel is the material containing fissile atoms. 2. A coolant removes heat from the reactor core and transfers it for electricity generation. 3. The turbine is placed inside the reactor core as the moderator. Which of the statements given above are correct?

Q4. 1. The technology development and design of PFBR were indigenously done by IGCAR. 2. PFBR was built and commissioned by BHAVINI. 3. PFBR incorporates high-temperature liquid sodium coolant technology. 4. PFBR is a conventional thermal reactor whose main design feature is ordinary-water cooling. Which of the statements given above are correct?

Q5. 1. In a PWR, the pressurizer keeps reactor-vessel water under very high pressure to prevent boiling. 2. In a BWR, water boils inside the pressure vessel and produces steam. 3. A BWR needs a steam generator because its turbine steam is produced in a separate secondary circuit. 4. In a PWR, steam for the turbine is produced in a steam generator. Which of the statements given above are correct?
