[3J09] Model Extension of Probabilistically Disordered Media and Its Implementation in Monte Carlo Solver Solomon

*TARO UEKI1 (1. Japan Atomic Energy Agency)

Keywords:probabilistically disordered, Monte Carlo, criticality, power spectrum, power law, Solomon

A dynamical system under extreme physical disorder has the tendency of evolving toward the equilibrium state characterized by an inverse power law spectrum. In this excerpt, a random media modeling under such a spectrum based on Weierstrass function is extended to cover a wider range of power law spectrum. Its capability is demonstrated on the platform of Monte Carlo solver Solomon for a randomized version of the Topsy sphere in International Criticality Safety Benchmark Evaluation Project.
