In the CORD project, new software toolsfor the numerical modelling of nuclear reactor cores in pressurized waterreactors are being developed. The WIMS-D library update with nuclear datafrom the ENDF/B-VII.1 library was the first task in that project. The performed procedures and results of the WIMS-D benchmark test calculations with the WIMS-D libraries updated with the data from the ENDF/B-VII.0 and ENDF/B-VII.1 libraries are briefly presented. In the DMR project, a new digital reactivity meter for measuring the time-dependence of the reactivity in the reactor core is being developed. The new DMR software will run on current MS Windows systems and will be compatible with current electronic measuring equipment. Tests of the beta version of the new DMR software, presented in this paper, showed good agreement of the results for the measuredreactivity with those obtained with the old DMR software, which is a validated MS-DOS application program and is considered as a reference toolPredstavljen je pregled načrtovanih dejavnosti in doseženih rezultatov v ZEL-EN-ovih projektih na področju reaktorske fizike CORD in DMR. V projektu CORD bo razvita nova računalniška programska oprema za numerično modeliranje reaktorske sredice v tlačnovodnih jedrskih reaktorjih. Prva naloga v tem projektu je bila posodobitev knjižnice jedrskih podatkov programa WIMS-D z jedrskimi podatki iz knjižnice ENDF/B-VII.1. Na kratko so predstavljeni izvedeni postopki in rezultati referenčnih testnih izračunov s programom WIMS-D, ki so uporabljali knjižnice jedrskih podatkov posodobljene s podatki iz knjižnic ENDF/B-VII.0 in ENDF/B-VII.1. V projektu DMR bo razvit novi digitalni merilnik reaktivnosti za merjenje časovne odvisnosti reaktivnosti v reaktorski sredici. Programska oprema novega DMR bo delovala na sodobnih računalniških sistemih z operacijskim sistemom MS Windows in bo kompatibilna ssodobno elektronsko merilno opremo. Testi beta verzije programske opreme novega DMR, predstavljeni v tem prispevku, so pokazali dobro ujemanje rezultatov za izmerjeno reaktivnost z rezultati pridobljenimi s programsko opremo starega DMR, ki deluje na MS-DOS-u in velja za referenčno orodjeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Mariboru, Fakulteta za energetiko
