INNOVATIONS IN MOBY-DICK CODE
17th Symposium of AER on VVER Reactor Physics and Reactor Safety (2007, Yalta, Crimea (Ukraine, back then))
SPECTRAL AND CORE CALCULATION
Abstract
During using of the macrocode Moby-Dick has surfaced that structure of the program has some limitations in accuracy of calculations. Many of these limitations originate in extensive using of the single precision representation of the real variables. These, along with other limitations, were removed and results of the comparison between old and new calculations are presented. Example of the calculation of the reactivity coefficients by the perturbation theory and by direct calculation is shown.
