Attempt this previous-year question. The correct option stays hidden until you choose.
With reference to radioisotope thermoelectric generators (RTGs), consider the following statements:
1. RTGs are miniature fission reactors.
2. RTGs are used for powering the onboard systems of spacecrafts.
3. RTGs can use Plutonium-238, which is a by-product of weapons development
Which of the statements given above are correct?
Pick an option to check yourself.
• Correct Answer: B
• RTGs convert heat from radioactive decay into electricity via thermocouples; they are not miniature fission reactors.
• They power spacecraft onboard systems and use Plutonium-238, historically a by-product of weapons-grade Pu-239 production.
