This report summarizes the environmental surveillance activities conducted by Sandia National Laboratories, the US Environmental Protection Agency, and Reynolds Electrical and Engineering Company for the Tonopah Test Range operated by Sandia National Laboratories. Sandia National Laboratories` responsibility for environmental monitoring results extend to those activities performed by Sandia National Laboratories or under its direction. Results from other environmental monitoring activities are included to provide a measure of completeness in reporting. Other environmental compliance programs such as the National Environmental Policy Act of 1969, environmental permits, and environmental restoration and waste management programs are also included in this report, prepared for the US Department of Energy in compliance with DOE Order 5400.1.

Progress reports are presented for the following tasks: overview and progress of waste package project and container design; waste container design considerations (criticality analysis, experimental drift model); waste container alternate design considerations; thermal simulation of high level nuclear waste canister emplacement; structural analysis and design of nuclear waste package canister; robotic manipulation of the nuclear waste container; investigation of stress in a circular tunnel due to overburden & thermal loading of horizontally placed 21PWR multi-purpose canisters; investigation of faulted tunnel models by combined photoelasticity and finite element analysis; and transport phenomena in the near field.
