Abstract: An approximate linearization method is proposed for nonlinear neutron transport equations. The equation is deduced to a form suitable for Monte Carlo simulations. Numerical results show that it is reasonable. It provides a tool for simulating high energy neutron transportation.

Key words: nonlinear, neutron transport equation, Monte Carlo, high energy neutron
