20.500.12556/DKUM-86476 The Influence of Increased Moderator Temperature on the Nuclear Characteristics of the NPP Krško NPP Krško safety analysis has been performed in such a way to allow operation with primary system average coolant temperature - Tavg inside a prescribed range, which constitute the socalled operating window. The Tavg window enables certain flexibility to select an optimum value within the Tavg range taking into account safety, operational and economical considerations. Increase of the reactor coolant temperature in general improves thermodynamic efficiency of the Pressurized Water Reactor (PWR) plant yielding to increase in the electricity production. However, higher temperature causes lower water density in the reactor core altering the neutron moderation and consequently neutron transport in the reactor. This impact on the nuclear core characteristics is investigated for the NPP Krško reactor core. pressurized water reactor nuclear design calculations reactor coolant temperature optimization critical boron concentration Nuclear Powe Plant Krško jedrske elektrarne vodni reaktorji optimizacija temperature hlajenja reaktorja kritična koncentracija bora jedrska elektrarna Krško true false false Univerza v Mariboru, Univerzitetna založba Angleški jezik Slovenski jezik Znanstveno delo 2023-12-05 07:58:42 2023-12-05 08:10:43 2023-12-06 03:11:17 0000-00-00 00:00:00 2019 0 0 Str. 121-126 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2019-02-27 621.311.25(497.4Krško) 96247297 1024342620 7th_International_Symposium_on_Applied_Electromagnetics_2019.pdf 7th_International_Symposium_on_Applied_Electromagnetics_2019.pdf 1 F45E3E0C426CF39972874E76A14F3CDB 6e16604655f30905283a59b7d1d2841e4186a21348e765567276b4f9c47a03bb 46d28894-933d-11ee-add4-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174589 https://doi.org/10.18690/978-961-286-241-1.16 0 59daa178-933d-11ee-add4-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174590 Fakulteta za energetiko Univerzitetna založba Univerze v Mariboru Conference proceedings 0 0 0
