Small Modular Reactors MCQ — 77 Practice Questions with Answers

Q1. Consider the following statements about SMR technology options: 1. The only technology option being pursued for SMRs is molten-salt reactor technology. 2. Many near-term SMR candidates are based on proven water-cooled reactor technologies. 3. Some fast SMR designs may use liquid-metal coolants such as sodium or lead. Which of the statements given above are correct?

Q2. Consider the following statements about Small Modular Reactors (SMRs): 1. SMRs are generally designed to produce electricity up to 300 MW(e) per module. 2. SMRs can be designed for factory construction and shipment to utilities for installation. 3. SMRs are, by definition, only molten-salt reactors. Which of the statements given above are correct?

Q3. Consider the following statements about fuel enrichment in some SMR designs: 1. EIA states that HALEU is uranium enriched between 20% and 40% uranium-235. 2. EIA states that HALEU is more highly enriched than the sub-5% LEU fuel currently used in most nuclear reactors. 3. EIA states that higher enrichment could improve efficiency and performance, allow smaller reactor footprints, and reduce spent fuel waste. Which of the statements given above are correct?

Q4. Under the Nuclear Mission mentioned by Dr Jitendra Singh, what combination was announced for small modular reactors?

Q5. Consider the following statements: 1. Small Modular Reactors are generally advanced reactors that produce electricity of up to 300 MW(e) per module. 2. They can be deployed either as a single-module or a multi-module plant. 3. The IAEA defines SMRs as reactors of up to 700 MW(e) per module. 4. Their modularity means that the complete reactor must be fabricated only at the final plant site. Which of the statements given above are correct?
