New capabilities of the TDMCC code for the analysis of the fission rate distribution in weakly coupled systems are presented. The methods implemented in the TDMCC code to calculate the dominant ratio and Shennons entropy are considered. For systems with the dominant ratio value close to 1, the relation between the convergence rate of functionals and Shennons entropy is demonstrated. An example is given, in which underestimation of errors in the calculated functionals and the specifics of the algorithms used to solve the criticality problems lead to inconsistent results in various options of computations with small variations of the original system parameters.Keywords: Monte Carlo method, method of generations, a weakly coupled system, dominant ratio, Shennon entropy.
