The National Radioactive Waste Repository (NRAWR) is a facility located in close proximity to the Kozloduy Nuclear Power Plant. The first stage of the repository's construction was put into operation in 2026. It is designed for the storage of low- and intermediate-level radioactive waste generated on the territory of Bulgaria.
History and Development: The construction of the NRAWR began in 2017 with a ceremonial event. The decision to build it was made by the Council of Ministers in 2005, and the funding was provided by the International Kozloduy Fund.
Construction and Stages: The construction of the repository was carried out at the "Radiana" site. In the period 2017-2019, intensive construction was carried out, including excavation work, construction of roads and installations. A loess-cement base and a building for receiving and temporarily storing waste were built. The first stage of construction was completed in 2026.
Technical characteristics: The waste will be buried 12 meters underground in reinforced concrete containers, protected by five-stage engineering protection. The repository is designed for a filling period of 60 years, with a period of institutional control of 300 years.
Significance: The NRAWR is a key facility for the safe operation of nuclear facilities in Bulgaria and nearly closes the cycle in the safe operation and care for the environment. With it, Bulgaria joins the group of countries with developed nuclear energy.
