Zusammenfassung:Verification of the MRNK+KEDR-D software system being developed for calculating reactor dynamics is performed using the numerical benchmark-test PWR MOX/UO 2 Transient Benchmark. The nonstationary process leading to an abrupt change of power caused by injection of large positive reactivity ~1.1 ß in 0.1 sec is studied. Analysis and a comparison of the obtained results with similar calculations performed using different software showed that the compared parameters are in agreement with one another to within admissible deviations.
