Q. Consider the following statements:
1.A part of the fission energy carried away by neutrons is called the prompt fission neutron spectrum.
2.India is currently in the first-stage of nuclear power programme.
Which of the statement(s) given above is/are correct?
Answer: A
Notes:
Explanation –
Statement 1 is correct. The prompt fission neutron spectrum (PFNS) refers to the energy distribution of neutrons emitted immediately after fission, which is a critical component of nuclear reactors.
Statement 2 is incorrect. India has already progressed beyond the first stage of its nuclear power programme. The first stage involved the use of pressurized heavy water reactors (PHWRs) fueled by natural uranium, which has been operational since the 1960s. The country has since moved on to the second stage, which involves the use of fast breeder reactors (FBRs) fueled by plutonium, and is planning to transition to the third stage, which will utilize advanced heavy water reactors (AHWRs) fueled by thorium.
