Methods and devices relating to a nuclear light water reactor of the boiling water kind |
摘要 |
The present invention concerns a method of determining the R-factor for a bundle of nuclear fuel rods in a nuclear light water reactor of the boiling water reactor kind. The R-factor is a factor that accounts for the weighted local power influence on a fuel rod. A local R-factor ( R i ( z )) is determined for each fuel rod (i) in said bundle and for each of a plurality of levels (z) in an axial direction. The individual axial heat generation profile for a certain fuel rod ( i ) is taken into account when determining the local R-factors ( R i ( z )) for said fuel rod (i). The invention also concerns a processor configured for automatically determining the R-factor, a computer program product, a method of determining the critical power for a bundle of fuel rods, a nuclear energy plant, and a method of operating a nuclear energy plant. |
