The Annual Report 2016 on Radiation and Nuclear Safety in the Republic of Slovenia endorsed by the Government

On June 15, 2017 the Government of Slovenia endorsed »The Annual Report 2016 on Radiation and Nuclear Safety in the Republic of Slovenia« and sent it to the National Assembly to be discussed on.

The report, which is already more than 30 years prepared by the SNSA, summarizes all developments related to nuclear and radiation safety in 2016. The report is being translated into English language and will soon be available on the SNSA website.

During the reporting year a fundamental objective of nuclear and radiation safety "The protection of people and the environment from unnecessary harmful effects of ionizing radiation." has been achieved.


In 2016 there were no significant events in the field of nuclear safety and radiation protection. The Krško Nuclear Power Plant operated without any major problems. In the autumn of 2016 a regular refuelling outage was carried out, during which some significant modifications were implemented. Just before the start-up the outage was prolonged due to problems with the new built-in valves.

The Krško Nuclear Power Plant implemented a procurement process for a supplier of spent nuclear fuel dry storage, which was, unfortunately, prolonged for eight months due to the appeal of one of the bidders. The National Audit Committee invited nuclear experts to assess the technical solutions of the chosen bidder.

The intergovernmental Slovenian-Croatian commission for monitoring the performance of the contract on the ownership of the Krško NPP did not meet in 2016. Therefore, the Republic of Slovenia has not received a formal response from the Republic of Croatia on cooperation in the project on the disposal of low- and intermediate-level radioactive waste at the Central Storage for Radioactive Waste in Vrbina.

The ARAO, the Agency for Radwaste Management, continued its activities for building a low- and intermediate-level radioactive waste disposal site in Vrbina, Krško. Unfortunately, due to the unregulated financing in the first half of the year, the envisaged deadline for the start of its trial operation was moved forward to the year 2021. Due to increasing delays in this project the problem of the shortage of radioactive waste storage space continues to intensify. If the waste disposal site is not finished within the next three or four years, all of the currently available space will be filled and the NPP will not be able to continue operations.

At the Boršt hydrometallurgical tailings disposal site of the former uranium mine Žirovski Vrh in Gorenja Vas additional drainage intervention measurements were taken. These measurements will enable the drainage of the hinterland groundwater and water from the disposal site and thus will likely slow down the rock sliding. Work is to be continued in 2017.

In 2016 there were no major problems at the organisations and institutions that carry out radiation activities. At the same time, there were only a few interventions with regard to finding sources of ionising radiation in the field.

The National Assembly of the Republic of Slovenia adopted the Resolution on the National Programme for the Management of Radioactive Waste and Spent Fuel Management for the period 2016–2025, which determines the strategy and programme of activities in this field. With this resolution Slovenia continues to pursue the goals specified in the previous Resolution, the validity of which expired in 2015.

A thorough amendment of legislation in the field of radiation protection and nuclear safety was drafted, mainly due to new European Union Directives. A public debate on the new Act on Ionising Radiation Protection and Nuclear Safety was carried out. The National Assembly is expected to adopt the Act in 2017.
