Typical weight estimation methods with Monte Carlo method such as MCNP default, empirical formula, monoenergy neutron attenuation curve, MCNP Weight Window Generator and adjoint flux are described. The mono-energy neutron attenuation curve method is proposed by authors. Weights estimated by methods by empirical formula and monoenergy neutron attenuation curve are compared with those calculated by MCNP WWG method.
