of Slovenia is co-located at the Institute's reactor facility. This facility is used for storage of the low and intermediate level solid radioactive waste from the Reactor Center and other, non-Institute small waste producers such as medical, research, and industrial applications of ionising radiation. Nuclear power plant Slovenia's only nuclear power plant is the 696 MWe Krško Nuclear Power Plant, located in the eastern part of the country, which went into commercial operation on January 15, 1983. It was built as a joint venture by Slovenia and Croatia which were at the time both part of Yugoslavia. The plant is a Westinghouse Electric Company two loop, light water pressurized water reactor. The operating company Nuklearna Elektrarna Krško (NEK) remains co-owned by Slovenian and Croatian state-owned companies and provides more than one quarter of Slovenia's electrical power along with roughly a fifth of Croatia's. In 2019, the plant provided 22.3% of Slovenia's total energy supply. The plant provided 36.2% of the total electricity generated in Slovenia in 2019. The debate on whether and when to close the Krško plant intensified following the 2005-06 winter energy crisis which highlighted Slovenia's exposure to natural gas supply disruptions. Nuclear waste is disposed in storage facilities. Slovenia has left the possibility of reprocessing spent fuel open. The plant is expected to be operational until 2043, following agreement in 2020 between the Slovenia and Croatia governments. Proposed expansion of Krško Nuclear Power Plant The idea of increasing the amount of electricity produced by nuclear power in Slovenia has been explored several times since the Krško nuclear power plant was constructed. As all liquid and gas fossil fuels (e.g. petroleum products and natural gas) for consumption in Slovenia must be imported, Slovenia is seeking greater energy independence, in addition to seeking to be carbon neutral by 2050. GEN Energija also cites nuclear as a means to help ensure affordable, predictable and stable prices of electricity for Slovenia as motivations for another reactor at the Krkso site. GEN Energija described planning efforts for a second Krško unit, JEK 2, on their website as early as 2015. The parent company of the Slovenian owner of the plant, GEN Skupina, published a video in mid-2019 depicting a single new large reactor at the Krško site, to the west of the current reactor. Additionally, it was announced that GEN filed a request for a second reactor at Krško and was looking
