The Annual Report 2017 on Radiation and Nuclear Safety in the Republic of Slovenia endorsed by the Government

On June 27, 2018 the Government of Slovenia endorsed »The Annual Report 2017 on Radiation and Nuclear Safety in the Republic of Slovenia« and sent it to the National Assembly to be discussed on.

The report in the Slovenian language, which has been prepared by the SNSA for more than 30 years, summarizes all developments related to nuclear and radiation safety in 2017. The report has already been translated into the English language and is available at 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 2017 there were no significant events in the field of nuclear safety and radiation protection. The Krško Nuclear Power Plant operated without any major problems. Due to technical faults, the plant had to be stopped twice for a short period of time. The annual electricity production was very high as there was no regular outage this year.

The Nuclear Power Plant signed a contract for the construction of a spent nuclear fuel dry storage facility and for the completion of the multi-annual safety upgrade project. Next to the plant a lake from the new hydroelectric plant Brežice was formed, due to which it had to adjust the system for capturing and discharging water from the Sava River.


After ten years, the Krško Nuclear Power Plant hosted an international OSART mission for the fourth time. A group of foreign experts critically reviewed all aspects of the plant’s management and prepared a report with recommendations on how to improve the situation.

A similar EPREV mission visited all Slovenian institutions involved in dealing with possible nuclear or radiological accidents. Their recommendations are also useful guidelines for improvements in this area.


The Intergovernmental Slovenian-Croatian Commission for monitoring the performance of the contract on the ownership of the Krško NPP met in November 2017. At the meeting, Croatian representatives refused to participate in the project on the disposal of low- and intermediate-level radioactive waste at the Central Storage for Radioactive waste in Vrbina, as they were invited to do at the previous meeting in 2015. Therefore, a special group for negotiating the possibilities of joint disposal was formed. The Intergovernmental Slovenian-Croatian Commission also initiated the re-preparation of the renewed programme for the decommissioning and programme for the disposal of radioactive waste from the Krško NPP.

The ARAO, the Agency for Radwaste Management, has continued its activities for building a low- and intermediate-level radioactive waste disposal site in Vrbina, Krško. The environmental impact assessment procedure for the future disposal site was started. Unfortunately, all related procedures of the involved authorities have not accelerated as required, and thus the challenge remains as to how the Krško NPP will operate after 2021, when it is expected that all the storage capacities for such waste will be filled and the new disposal site will not yet be available.

At the Boršt hydrometallurgical tailings disposal site of the former uranium mine Žirovski Vrh the problems with landslide have not been solved, therefore the search for solutions continues.

In 2017 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 due to the finding of sources of ionising radiation in the field.

Mainly due to the new European directive, at the end of the year the National Assembly of the Republic of Slovenia adopted a new Ionising Radiation Protection and Nuclear Safety Act. This was a fundamental step entailing a major change in the legislation in the field of ionising radiation protection and nuclear safety.
