Q1Assertion: AERB's mission is concerned with preventing undue risk to people and the environment from the use of ionising radiation and nuclear energy in India. Reason: AERB is tasked with promoting commercial electricity sales by nuclear power stations.

A The Assertion is true, but the Reason is false
B The Assertion is false, but the Reason is true
C Both the Assertion and the Reason are true, but the Reason does not explain the Assertion
D Both the Assertion and the Reason are true, and the Reason correctly explains the Assertion
Explanation

The Assertion is true because the cited AERB mission is to ensure that ionising radiation and nuclear energy in India do not cause undue risk to people or the environment. The Reason is false because commercial electricity generation and sales are not stated as AERB's mission in the cited fact; that wording points away from a regulatory safety mandate.

Q2Consider the following Assertion and Reason about entities licensed under the SHANTI Act. Assertion: Such entities are responsible for nuclear material monitoring and accounting as well as radioactive-waste management. Reason: Such entities are also responsible for safe operation and decommissioning of nuclear facilities. Which one of the following is correct?

A Both the Assertion and the Reason are true, and the Reason correctly explains the Assertion
B The Assertion is false, but the Reason is true
C Both the Assertion and the Reason are true, but the Reason does not explain the Assertion
D The Assertion is true, but the Reason is false
Explanation

The Assertion is true because the PIB reply assigns licensed entities responsibility for nuclear material monitoring and accounting and for radioactive-waste management. The Reason is also true because the same fact assigns them responsibility for safe operation and decommissioning of nuclear facilities. These are parallel responsibilities, so safe operation and decommissioning do not explain why monitoring, accounting and waste management are also assigned.

Q3Consider the following statements about NPCIL's commercial nuclear power reactors as per its overview. 1. NPCIL operates 24 commercial nuclear power reactors. 2. Their installed capacity is 8,780 MW. 3. This count and capacity include RAPS-1. Which of the statements given above are correct?

A 1 only
B 2 and 3 only
C 1, 2 and 3
D 1 and 2 only
Explanation

Statement 1 is correct because NPCIL operates 24 commercial nuclear power reactors. Statement 2 is correct because the installed capacity is 8,780 MW. Statement 3 is wrong because the cited overview expressly excludes RAPS-1 from this count and capacity.

Q4Assertion: BARC Training School was established by Dr Homi Bhabha. Reason: It was set up to meet the manpower needs of India's expanding atomic energy research and development programme. Select the correct answer.

A Both the Assertion and the Reason are true, but the Reason does not correctly explain the Assertion
B The Assertion is false, but the Reason is true
C The Assertion is true, but the Reason is false
D Both the Assertion and the Reason are true, and the Reason correctly explains the Assertion
Explanation

The Assertion is true because the cited BARC account attributes the establishment of BARC Training School to Dr Homi Bhabha. The Reason is also true because the same fact states that the school was meant to meet manpower needs for India's expanding atomic energy research and development programme. Since that manpower need is the stated purpose for establishing the school, the Reason directly explains the Assertion.

Q5Match the BARC small modular reactor design with the capacity or purpose stated in the official update. Design 1. BSMR-200 2. SMR-55 3. High-temperature gas-cooled reactor Capacity or purpose a. 55 MWe b. 200 MWe c. Up to 5 MWth for hydrogen generation

A 1-a, 2-b, 3-c
B 1-c, 2-a, 3-b
C 1-b, 2-a, 3-c
D 1-b, 2-c, 3-a
Explanation

BARC initiated three SMR designs: BSMR-200 at 200 MWe, SMR-55 at 55 MWe, and a high-temperature gas-cooled reactor of up to 5 MWth for hydrogen generation. Pairings that swap BSMR-200 with SMR-55, put the hydrogen-generation reactor against 55 MWe, or assign 200 MWe to the gas-cooled reactor contradict the cited fact.
