GENERAL KNOWLEDGE

Detailed explanation-1: -Nuclear energy produces radioactive waste A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.

Detailed explanation-2: -Disadvantages. The radiation emitted during the fission reaction is extremely harmful to humans and animals. The workers who are exposed while working at nuclear power plants are at great risk radiation poisoning, cancer and other diseases associated with radiation.

Detailed explanation-3: -Answer: Statement that is not true about nuclear energy generation is Option B: the nucleus of uranium is bombarded with high energy neutrons. Explanation: Nuclear energy is generated by splitting of uranium atoms.

Detailed explanation-4: -Radioactive decay of both fission products and transuranic elements formed in a reactor yield heat even after fission has ceased. Fission reactions may be moderated to increase fission, or unmoderated to breed further fuel. For reactors using light water as moderator, enriched uranium is required.
