AbstractAbstract
[en] Neutronic calculations to verify the reactivity effects, of sodium voids and Doppler, with the variation of the composition of parasitic absorbers were done. A LMFBR type reactor loaded with mixed fuel, (U233-Th232)O2 in the internal core and (U238-Pu239)O2 in external core, was considered. In reactivity calculations the EXPANDA and CITATION computer codes were utilized. Buckling effects and importance of determination of the spatial selfshielding factors were analysed. (M.C.K.)

Foram feitos calculos neutronicos para verificar os efeitos de reatividade, de vazios no sodio e de Doppler, com a variacao da composicao de alguns absorvedores parasiticos. Considerou-se um reator do tipo LMFBR carregado com combustivel misto, sendo (U233-Th232)O2 no nucleo interno e (Pu239-U238)O2 no nucleo externo. Nos calculos de reatividade foram utilizados os codigos EXPANDA e CITATION. Efeitos das variacoes de curvaturas ('bucklings') e importancia da determinacao dos fatores de autoblindagem espacial foram analisados. (M.C.K.)Original Title
