A review of three documents prepared for the USNRC by Sandia National Laboratories (SNL) is presented. These are NUREG/CR-1634, Volume 4 concerned with the effects of variable hydrology on waste migration; NUREG/CR-2324, a user's manual for SWIFT; and NUREG/2343, a user's manual for DNET. This review completes Task 4 of the detailed technical review of the SNL program for Risk Assessment Methodology Development for Waste Isolation in Geologic Media. In general, these reports exhibit high technical quality that characterizes the SNL work. They are tersely written with little condescension to the non-expert reader for understanding the physical situation being modeled. Indeed, the emphasis is on the mathematical procedures rather than the repository physics, leaving the adequacy of the results presented in many computer plots, pretty much to the interpretation of the reader. Other general comments have been presented previously, such as the data conservatisms, need for data that cannot be measured without disturbing the geometry, and the overall plan for use of the many codes developed in the program.
