Nuclear energy is a very clean source as it produces almost no greenhouse gases, such as CO2 . Under the Kyoto Protocol, the signatory countries committed themselves to reducing CO2 emissions; therefore, it is reasonable to take advantage of existing nuclear facilities to the greatest extent possible. This means that even though they were built only to produce electricity (Krško NPP, for example), they can also be used for other applications: a source of heat for district heating or desalination of sea water in areas at risk of a lack of drinking water. Nevertheless, the technology can be upgraded by using the experience of other nuclear power plants (NPPs) having similar district-heating systems. In this paper, the focus was on models of steam consumption from the secondary system of the Krško NPP for the Krško and Brežice district-heating purposes. The Krško NPP has a Westinghouse PWR with 2,000 MWt and an electrical power output of 696 MW to the grid. The technological part is divided into three main systems: primary, secondary and tertiary. The first two are sealed and isolated from the environment while the third, which uses water from the River Sava for cooling, is connected to the outside environment. This paper focuses on the technical solution to obtain heat from the NPP's secondary system for district-heating purposes. According to thermodynamic calculations, the secondary system determines the reduction of produced electricity, when the steam is exploited in front of the turbine. This paper presents some technical, economic and safety solutions for the highly efficient extraction of vapour for district heating. Furthermore, some thermodynamic calculations and technical solutions for district-heating purposes using the Krško NPP for the Krško-Brežice area are shown"},{"@xml:lang":"sl","#text":"Nuklearna energija se v svetu izkorišča za proizvodnjo električne energije, kot tudi za kogeneracijo % torej proizvodnjo električne energije in toplote. Velja za čisti vir energije, saj v procesu ne nastajajo toplogredni plini, predvsem CO2 . Po Kjotskem protokolu so države podpisnice zavezane k zmanjšanju izpustov CO2 , torej bi bilo smiselno obstoječe jedrske objekte izkoristiti v največji mogoči meri. To pomeni, da bi jih tam, kjer so namenjeni samo za proizvodnjo električne energije (kot NEK), uporabili tudi za druge aplikacije, kot je izkoriščanje toplote v namen daljinskega ogrevanja ali razsoljevanja morske vode na območjih, kjer so velike možnosti za pomanjkanje oskrbe s pitno vodo. Pri tem si lahko pomagamo z izkušnjami iz ostalih nuklearnih elektrarn, ki že imajo podobne sisteme za kogeneracijo. V našem primeru se bomo osredotočili na odjem pare iz sekundarnega kroga NEK za sistem daljinskega ogrevanja Krškega in Brežic. NEK ima Westinghouseov PWR z 2000 MWt in z močjo na pragu 696 MW. Tehnološki del je razdeljen na primarni, sekundarni in terciarni krog, prva dva sta sklenjena in nimata stika z okoljem, tretji pa je povezan z okoljem, saj uporablja vodo iz Save za hlajenje. V članku je poudarek na tehnični rešitvi pridobivanja toplote iz sekundarnega kroga NEK za sistem daljinskega ogrevanja. Po termodinamične izračunu lahko določimo, koliko bi se zmanjšala proizvedena električna energija, saj bi paro odjemali pred turbino. V članku so predstavljene nekatere tehnične, ekonomske in varnostne rešitve za čim bolj učinkovito odjemanje pare za daljinsko ogrevanje. Nadalje so prikazani termodinamični izračuni in tehnične rešitve za sistem daljinskega ogrevanja s pomočjo NEK za območje Krškega in Brežic"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-GBUCD22X","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-GBUCD22X"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-GBUCD22X/f6b34cc9-8860-42c0-9dd3-33a01a5dfe5d/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Mariboru, Fakulteta za energetiko"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-GBUCD22X/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-GBUCD22X"}}}}
