Generalized Albedo Option in the Morse Monte Carlo Code

The advisability of using albedo procedure for solving deep penetration shielding problems which have ducts and other penetrations is being investigated. It is generally accepted that the use of albedo data can dramatically improve the computational efficiency of certain Monte Carlo calculations; however, the accuracy of these results may be unacceptable because of lost information during the albedo event and serious errors in the available differential albedo data. This study has been done to evaluate and appropriately modify the BREEZE¹/MORSE² package and to develop new methods for generating the required albedo data.
