Mention the disadvantages of the nuclear reactor.

(N/A) The fission process in a nuclear reactor generates considerable waste products.
These nuclear wastes need special care for treatment since they are radioactive and hazardous.
Elaborate safety measures,both for reactor operation as well as handling and reprocessing the spent fuel,are required.
An appropriate plan is being evolved to study the possibility of converting radioactive waste into less active and short-lived material.
