= Waste =

The most important waste stream from nuclear power plants is spent nuclear fuel. It is primarily composed of unconverted uranium as well as significant quantities of transuranic actinides (plutonium and curium, mostly). In addition, about 3% of it is fission products from nuclear reactions. The actinides (uranium, plutonium, and curium) are responsible for the bulk of the long-term radioactivity, whereas the fission products are responsible for the bulk of the short-term radioactivity.

Radioactive Waste Management Policy and Strategy in RA
To define safe and sustainable management of radioactive waste and spent nuclear fuel in the Republic of Armenia the Government of RA approved the Policy on safe management of radioactive waste and spent fuel in RA by the Government Protocol Decree 43 as of 4 November 2010. The Strategy of radioactive waste and spent nuclear fuel management is in the stage of development in the Republic of Armenia.

Storage of spent fuel
The dry spent fuel storage facility (DSFS) of NUHOMS-56 type is located on Armenian NPP site. Spent fuel is stored in special designed spent fuel pools. After five years of storage the spent fuel is placed into dry shielding container (DSC) of NUHOMS-56M type and is placed into horizontal storage modules (HSM). DSFS consists of 11 horizontally placed concrete modules for storage of 616 spent fuel assemblies. After shutdown of Unit No. 1 of Metsamor Nuclear Power Plant its spent fuel pool is used as a temporary storage facility for spent fuel.
