INRNE-BAS and the US Department of Energy conduct a successful radiation safety training

The Institute for Nuclear Research and Nuclear Energy at the Bulgarian Academy of Sciences (INRNE-BAS) hosted a key final training on the search and security of radioactive sources, carried out in close cooperation with the US Department of Energy. The event, which took place on 6 June, was part of a global effort to enhance the safety, control and safe disposal of radioactive materials worldwide. The training brought together leading experts from INRNE-BAS, their counterparts from Slovakia, as well as experts from various institutions involved in safety when handling radioactive materials. The U.S. Department of Energy's Search and Security Program provided not only advanced radiation detection equipment but also valuable training held June 2-6, 2025 in Sofia. It covered all stages of the process: from [...]

The President of the Parliament joins the BAS initiative “Peaceful Atom-Green Planet”

An initiative under the "Peaceful atom-green planet" motto was held today at Science Complex 2 of the Bulgarian Academy of Sciences. The event marked the 39th anniversary of the Chernobyl NPP. The President of the National Assembly Nataliya Kiselova and the President of BAS Corr. Memb. Evelina Slavcheva took part in the initiative organized by the Institute for Nuclear Research and Nuclear Energy (INRNE) in cooperation with the Institute of Solid State Physics, the Institute of Electronics, the Central Laboratory of Solar Energy and New Energy Sources and the State Enterprise "Radioactive Waste".

50 years since the invention of the copper bromide vapour laser in Bulgaria

Jubilee Scientific Session "From the Idea to the Industrial Product" Fifty years since the development of the copper bromide vapour laser by Acad. Nikola Sabotinov were celebrated at a scientific session at the Bulgarian Academy of Sciences. Acad. Nikola Sabotinov's idea of creating a low-temperature copper laser in Bulgaria was realized in 1974 when under his leadership at the Institute of Solid State Physics (ISSP) a copper bromide vapour laser was launched and recognized as the invention of the year in 1979. In order to improve its characteristics, a number of theoretical and experimental studies had been carried out, and the effect of hydrogen was discovered. Thus, the most powerful entirely Bulgarian gas laser generating in the visible region of the electromagnetic spectrum was created [...]
