2014 Annual Reports on Radiation and Nuclear Safety in the Republic of Slovenia prepared

The SNSA prepared »The Annual Report 2014 on Radiation and Nuclear Safety in the Republic of Slovenia«, which was approved by the Expert Council for Radiation and Nuclear Safety. The report was adopted by the Slovenian Government at the 43rd regulary sitting on 24 June 2015. The report will also be discussed by the National Assembly.


In the field of nuclear safety and radiation protection, the year 2014 was one of the quietiest years in recent years. At the Krško Nuclear Power Plant there were no obstructions worth mentioning. It operated the whole year without interruption. For the first time the Krško NPP exceeded the magical limit of 6 TWh of electrical energy produced due to a year of no outages and enough water from the Sava river. There were no deviations from normal operation that would need to be reported to the Slovenian Nuclear Safety Administration. In the autumn the owners of the Krško NPP aproved an investment in the safety upgrades programme in accordance with requirements on the basis of the lessons learned from the Fukushima accident.

After the fuel damage identified during the 2013 outage, the SNSA carefully monitored the implementation of corrective actions. By the end of the year there were no indications of any leakage of nuclear fuel and there were no problems due to electromagnetic interference, which could have caused the automatic shutdown in November 2013.

In 2014, the Second Periodic Safety Review of the NPP, which has to be performed once every ten years by each nuclear facility, was completed. After a detailed examination, which lasted several years, no deficiencies were identified that would require immediate action. An improvement plan was made to address the identified discrepancies. Confirmation of the results of the periodic safety review entails an extension of the operating license for the next ten years.

Activities for the construction of the future radioactive waste repository have moved from the stalemate, as the Minister for Infrastructure signed an investment programme in the summer. Field research has been carried out and the designer was selected.

The intergovernmental Slovenian-Croatian commission, which should monitor the performance of the contract on the ownership of the Krsko NPP, has not met since 2010, which leads to delays in taking important decisions.
Disposals sites at the former Žirovski Vrh uranium mine survived an extremely powerful storm in autumn that resulted in only minor damage to overlays and drainage devices at the Jazbec disposal site. Unfortunately, due to a lack of funds, remediation has not been implemented yet at the disposal site Boršt, where a few years ago a problem with long-term landslide movement became apparent. ARAO is preparing for long-term monitoring control and maintenance of the disposal site Jazbec.

The “Jozef Stefan” Institute has increased the range and number of research studies at the TRIGA research reactor. At the same time, it completed a ten-year Periodic Safety Review, which confirmed the adequacy of the nuclear safety and extended the operating license for ten years. The Reactor Physics Department is active and successful in international research circles.

In 2014, there were no major problems at the organisations that carry out radiation practices. At the same time, there were also fewer interventions with regard to finding sources of ionizing radiation in the field.
In September 2014 an International IRRS Follow-up Mission found that most of the recommendations and proposals of the previous mission in 2011 had been fulfilled, but some of them remain unresolved, inter alia, ensuring sufficient funds for the work of the SNSA and for the development of the Slovenian nuclear profession and delays in the construction of the repository for low and intermediate level waste (LILW).

Due to the resignation of the government in the spring and subsequent summer elections, the adoption of amendments to the Ionising Radiation Protection and Nuclear Safety Act has stalled. The process of adopting the amendments to the Act resumed after the formation of the new government and will be completed in 2015.
