Other methods

In recent years, many innovative numerical methods have been proposed to solve the neutron transport equation for complex geometry. This chapter introduces some basic ideas of three of these methods. The idea of the wavelet method is very similar to PN method, but the basic function is a new set of compactly supported orthonormal wavelets called “Daubechies wavelets.” Heterogeneous variational nodal method is proposed to solve the second-order even parity form of the neutron transport equation. The hybrid of deterministic MOC and Monte Carlo method is also attracting more and more interests in reactor physics community. The theoretical models of these three methods are briefly introduced along with some numerical results.
