Name: radioactive waste (LLW) and intermediate-level radioactive waste (ILW).

Name: Ahmed Siyad MohamedCommittee: International Atomic Energy AgencyTopic: Nuclear Water DisposalCountry: NorwaySchool: United States International UniversityNuclear waste is a threat to all; plant life, animal life and even the soil.

As such, ensuring that it is disposed safely is of utmost importance. Nuclear waste has adverse health effects and given the decay rates of nuclear material such as Uranium, poor disposal of the waste could render an area uninhabitable for decades if not hundreds of years. The disposal of nuclear material must be monitored closely and and be well maintained to ensure no leakage occurs. As such, the International Atomic Energy Agency recommends that certain measures be followed and suggests the following methods as well as protocol to be observed in the production of nuclear energy.There are two main methods of disposing the nuclear waste; Near surface disposal- at ground level or in caverns below ground level usually at depths of ten metres. Deep geological disposal- 250 to 1000 metres for mined repositories and 1000 to 2500 metres for boreholes. Near surface disposal is suggested for low-level radioactive waste (LLW) and intermediate-level radioactive waste (ILW). Deep geological disposal is suggested for long-lived ILW and high-level radioactive waste (HLW).

We as the International Atomic Energy Agency do however, strongly recommend that countries invest in deep geological disposal methods. Deep geological disposal involves the disposal of nuclear waste into geological repositories such as rocks or clay. This method is widely adapted in developed nations such as the USA, Russia, United Kingdom and Canada. Adopting this method leaves less of an obligation of active maintenance on future generations. Some methods of deep geological disposal involve mined repositories and deep boreholes. The mined repositories are used more widely in comparison to deep boreholes however, more countries are beginning to use the boreholes as a secondary method of disposal.

Other methods of disposal we may encourage nations to research into for future us are; Long-term above ground storageSea disposalSeabed disposalDeep well injection especially liquid wasteThese are just but a few methods. Countries are encouraged to follow the guidelines and protocols in place through the various international agreements.
