Abstract
A modified power iteration method is implemented in continuous energy Monte Carlo simulation, and the convergence acceleration performance of this modified method is studied. Instead of powering out the higher modes, the modified power iteration method can accelerate the convergence of the first mode by subtracting the second mode. Numerical tests have confirmed that the modified power method outperforms the original power method a lot by accelerating the fission source convergence greatly.
