This paper introduces a direct simulation method for estimating nuclide concentrations after transmutations. The method directly simulates the transformation of nuclides, making it self-contained and eliminating the need to solve Bateman equations. This approach maintains physical intuition and provides a deeper understanding of complex transmutation processes. While direct simulation can be computationally expensive, the method can be implemented in parallel, yielding reasonable computational times. Verification with other studies demonstrates that the proposed method is consistent and able to reproduce reference solutions when appropriate calculation input is used. While not claiming superiority over existing methods, our approach offers a valuable alternative with potential use as a reference calculation of nuclide concentrations. •We proposed a method to compute nuclide concentrations during transmutations.•Prediction of transmutation events using truncated joint Poisson distribution.•Implements fast parallel SpMM with high-precision floating point arithmetic.•Valuable tool for researchers and students studying transmutation problems.
