Replacing fossil fuel by nuclear fuel more clean power will be produced and greenhouse effect which is an environment threat is to be decreased the comparison between fossil fuel and nuclear fuel can reveal the clean power claim. Fuel packaging, preparation& designing must be completed. Final removals of high- level radioactive wastes are accomplished which require more time for continue and serious working, selecting the final site of burial is important. The obstacles in this area are Concerns about spread and production of nuclear waste and Threats of environment contamination due to nuclear waste. Significant problem in special field is that nuclear wastes disposal is a necessity to inhibit radioactive effluence. This book aimed to introduce management and procedures of nuclear waste disposal. Managing nuclear waste collection, keeping, compatibility to environment and finally fuelling the burial site & cooling them are the important jobs that must protect the environment.
