20.500.12556/DiRROS-23891 Advanced Monte Carlo analysis of ex-vessel neutron dosimetry for cycle 25 of Krško nuclear power plant This paper presents the results of Monte Carlo neutron transport calculations performed for the containment building of the Krško Nuclear Power Plant. The calculations were performed using the Monte Carlo N-Particle Transport Code (MCNP) in combination with the ADVANTG hybrid code to speed up the convergence of the results outside the reactor core. The paper focuses on the analysis of the Ex-Vessel Neutron Dosimetry (EVND) program conducted during the 25th fuel cycle at the Krško nuclear power plant with the irradiation of gradient chains and multiple foil sensor sets. The calculated reaction rates at the dosimeter locations are in good agreement with the measured values. However, deviations were observed in the thermal part of the neutron energy spectrum which cannot be neglected, and investigated were some possible reasons for the deviations: nuclear data, concrete material composition, concrete geometry, sensor position and impurities in sample. neutron transport ex-vessel neutron dosimeters neutron transport nevtronov dozimetri true false true Elsevier Južna Koreja Angleški jezik Slovenski jezik © 2025 Korean Nuclear Society, Published by Elsevier Korea LLC Neznano 2025-10-20 09:40:52 2025-10-20 09:40:53 2025-10-24 03:55:14 0000-00-00 00:00:00 2026 0 0 Nasl. z nasl. zaslona; Soavtorji: Benjamin Barbarič, Vladimir Radulović, Dušan Čalič, Luka Snoj, Marjan Kromar; Opis vira z dne 15. 10. 2025; str. 1-37 iss. 1, [article no.] 103887 Vol. 58 Jan. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-06-16 2025-08-26 2025-09-01 539.1 2234-358X 10.1016/j.net.2025.103887 253273091 https://www.sciencedirect.com/science/article/pii/S1738573325004553 1 1c033be5-ad88-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35445 RAZ_Goricanec_Tanja_2026.pdf RAZ_Goricanec_Tanja_2026.pdf Raziskovalni podatki so na voljo na povezavi: https://zenodo.org/records/14887749. 1 0553556B14412D9ADC3DCA27B84166A6 8949d97ba192734052d33a45ab78a689d72ad23aec11121b6c78936bae337ee2 ed85cf9d-ad88-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35446 Institut Jožef Stefan 0 0 0
