State Enterprise Radioactive Waste (SE RAW) was founded on January 1, 2004 pursuant to the Act on the Safe Use of Nuclear Energy. The goal is the establishment of a national operator for management of radioactive waste outside the sites generating them, in compliance with the National Strategy for RAW and SNW Management and with the relevant international practices.

The legal registration of the Enterprise was done on June 8, 2004. As of 2008, this date has been celebrated as SE RAW official holiday.

The first division in the structure of the Enterprise is the Specialized Division in Kozloduy, which comprises a shop for processing and conditioning of RAW generated from the operation of Kozloduy NPP and a storehouse for temporary placement of the same. In 2005, a new specialized division was joined to SE RAW – the Permanent Repository near the village of Novi Han, which had by then been managed by the Institute for Nuclear Research and Nuclear Energy within the Bulgarian Academy of Sciences. At the end of 2008, the beginnings of a third specialized division were laid. It was designed to manage the closed Units 1 and 2 of the nuke as RAW management facilities. November 1, 2012 is the date of official registration of the fourth specialized division within SE RAW – the National Repository for Radioactive Waste. SE RAW has all required documents and licenses issued by the authorized agency for nuclear safety control – the Bulgarian Nuclear Regulatory Agency. The Enterprise has all licenses for the operation of Nuclear Facility for Radioactive Waste Management through specialized Division RAW Kozloduy and through specialized division PRRAW Novi Han, as well as a license for transportation of radioactive material. On October 18, 2010, we were granted also licenses for operation of Kozloduy NPP Units 1 and 2 as facilities for radioactive waste management.
