(b) sustain the reaction
(c) dispose off spent fuel safely
(d) convert nuclear energy into electrical energy

Answer 1

Answer:

C. dispose off spent fuel safety

Answer 2

$\bf\huge\underline\mathtt\red{Answer}$

(c) dispose off spent fuel safely.

The major hazard of nuclear power generation is the storage and disposal of spent or used fuels. Improper nuclear-waste storage and disposal result in environmental contamination, as well as, risk of accidental leakage of nuclear radiation. The high cost of installation of a nuclear power plant, high risk of environmental contamination and limited availability of uranium makes large-scale use of nuclear energy prohibitive.
