AbstractAbstract
[en] Achievement of the acceptable accuracy in the hexagonal geometry neutronic calculations requires usually a considerable number of mesh points and/or finite elements if finite difference or finite element approach is used. This is particularly true in the three dimensions, therefore the coarse mesh methods in three dimensions have a special importance. An interface current method implemented in the code SIXTUS-2 for two dimensions has been found to be very fast and accurate, therefore an effort has been initiated by the Osaka University to extend it to three dimensions. As a result of the common development the three-dimensional, nodal, multigroup code SIXTUS-3 has been written and succesfully verified both in Japan and Switzerland. (author) 10 refs
