Krsko Nuclear Power Plant, Slovenia


The construction of Krško NPP started in year 1975 and was concluded in 1981. During 1982 numerous test were performed and in January 1983 Krško NPP started with commercial production. One year later regular operation of Krško NPP was approved. Introduction of nuclear energy was a great challenge for involved scientific and technical experts, legislators, and all domestic companies acting either as contractors or subcontractors.

Project Details and Actors
Project DetailsNEK is equipped with a Westinghouse Pressurised Light Water Reactor of 2.000 MW thermal power. The power plants net electrical power is 696 MW. It is connected to the 400kV grid supplying power to consumer centres in Slovenia and Croatia. The total installed output of the power stations is 2.834 MW, from which represents slo share of npp Krško 14% (384 MW of 696 MW total power).

Expected lifetime of NEK is 40 years, with activities fot its extension for another 20 years.

In 2011, the Krško NPP produced 6,214,748.0 MWh (6.2 TWh) gross electrical energy on the output of the generator, which corresponds to 5,902,238.8 MWh net electrical energy delivered to the grid.

Do you consider this as a success?No
Why? Explain briefly.The lifetime of the current reactor is prologned by 50 % (20 years) without performing EIA, which would be in line with the ESPOO convention. Another reactor is planned to be constructed and is included in the development plans of Slovenia. No permanent site is selected for LILW storage (currently, LILW is stored at the reactor). The whole site (current reactor, storage and planned reactor) is located in a seizmically active area).
Sources and Materials

Decree on checking the radioactivity for shipments of metal scrap (Off. Gat. RS, 84/07),

Regulation on the monitoring of radioactivity (Off. Gaz. RS, 20/07)

Slovenian legislation relating to nuclear safety and radiation protection is comprehensive and in line withinternational standards. In the strictest sense of the practical application of the area regulated by the Radiation Protection and Nuclear Safety (ZVISJV14). In its legislation, Slovenia has transferred the basic standards of the International Agency forAtomic Energy. Wider field of nuclear and radiation safety is regulated by legislation on responsibility for nuclear damage, exports of dual-use items (ie, that could be used to make nuclear weapons), the transport of dangerous goods, regulations that govern the operation of utilities for radioactive waste management, the fund for the decommissioning of Nuclear Power Plant and disposal of radioactive waste from nuclear power plant, the permanent cessation of exploitation of uranium and prevention of the effects of mine uranium mine, physical security regulations in the field of protection and rescue, etc..

The most important legal instrument in the area of nuclear and radiation safety in the Republic of Slovenia is the Act on Protection against Ionizing Radiation and Nuclear Safety (ZVISJV, Off. Gaz.RS,102/04 – official consolidated text). Based on the ZVISJV, twenty-one implementing regulations were adopted at the beginning of 2007, namely four governmental decrees, six regulations issued by the minister of the environment, nine issued by the minister of health and two issued by the minister of the interior. In 2007 the adoption of implementing regulations continued and the following regulations were issued:
