The Bulgarian Ministry of Environment and Water (MEW) has allowed the construction of a new repository for disposal of radioactive waste. The proposal was made by the public company Radioactive Waste and accepted by the Ministry on September 21st, 2011. The terrain selected for the repository is near the nuclear power plant at Kozloduy and will stretch over 36 hectare and is to be completed by 2015.
The new site will be for the proper disposal of low- and intermediate- level radioactive waste. According to the World Nuclear Association, the former is generated from hospitals and industry, as well as from nuclear reactors. It constitutes 90% of all waste generated from atomic energy but contains only 1% of the total radioactivity. The latter is the result of dismantled internal structures of the reactor core and arise after prolonged operation. It is treated by the addition of cement or an organic solid and then situating it in containers for shielding and underground storage. According to specifications for the new disposal facility, all international standards will be met in its construction.
However, some environmental concerns remain on the agenda. For instance, 400 m from the site of the planned waste dump is an area called “Zlatiyata” which is protected under the eco-network Natura 2000. The official report by the MEW states that an ecological investigation shows that the radioactive burial site’s possible effects on the protected zone are “unlikely” to be negative. However, any problem that might occur in the disposal of waste would definitely harm the surrounding environment.
Furthermore, the planned site is currently covered by forest which will have to be cleared before construction can begin. Although the National Ecological Council has requested that the forest be re-planted in a different area, there is no guarantee that this will happen. In the worst-case scenario, Bulgaria is set to lose 36 hectares of forest to make way for an atomic waste dump.
In addition to this, the decision to allow the construction was prematurely taken under pressure from the European Union. The Minister for Environment and Water, Nona Karadjova, signed the agreement because of a commitment Bulgaria has made to the EU to construct such a repository before 2015, which is legally embedded in the national strategy for nuclear waste disposal. The commitment was made after the decommissioning of two reactors at the Kozloduy nuclear power plant.
Overall, the construction of a radioactive waste disposal facility is a necessary evil for a country using atomic energy. The decision for its placement and the pressure to construct it as quickly as possible are concerns that have to be monitored by the authorities. If not, an environmental disaster of epic proportions could occur.
