This talk is about how to avoid turning swords into Superfund sites. The problem we address is the potential conflict between the desire to take advantage of the greater international security brought by the end of the Cold War by entering arms control agreements requiring various military weapons to be dismantled, and the desire to avoid further degrading the environment in the process of destroying them. We will use as an illustration of these issues the Chemical Weapons Convention (CWC), which is intended to cause the destruction of all chemical weapons in the world. First, we will provide a brief overview of the CWC, then we will focus in on its environmental provisions, and, finally, we will discuss potential conflicts with United States law and how they might be resolved.

This document is a plan which serves as the contractual agreement between the Characterization Program, Sampling Operations, WHC 222-S Laboratory, Oak Ridge National Laboratory, and PNL 329 Laboratory. The scope of this plan is to provide guidance for the sampling and analysis of vapor samples from tank 241-BY-103.

This analysis examines activities associated with the installation of isolation barriers in the K Basins at the Hanford Reservation. This revision adds evaluation of barrier drops on stored fuel and basin floor, identifies fuel which will be moved and addresses criticality issues with sludge. The safety assessment is made for the activities for the preparation and installation of the discharge chute isolation barriers. The safety assessment includes a hazard assessment and comparisons of potential accidents/events to those addressed by the current safety basis documentation. No significant hazards were identified. An evaluation against the USQ evaluation questions was made and the determination made that the activities do not represent a USQ. Hazard categorization techniques were used to provide a basis for readiness review classifications.

The Advisory Committee on Human Radiation Experiments was created by President Clinton to advise the Human Radiation Interagency Working Group on the ethical and scientific criteria applicable to human radiation experiments carried out or sponsored by the U.S. Government. The Committee seeks to answer several fundamental question: What ethics criteria should be used to evaluate human radiation experiments? What was the Federal Government`s role in human radiation experiments? What are the criteria for determining appropriate Federal responses where wrongs or harms have occurred? What lessons learned from studying past and present research standards and practices should be applied to the future? The Committee has been gathering vast amounts of information and working to render it orderly and accessible. In the next six months, the Committee will continue with the tasks of data gathering and organizing. The focus of the work, however, will be developing criteria for judging historical and contemporary experiments, policies, and procedures, as well as criteria for remedies that may be appropriate where harms or wrongs have ocurred. Based on findings, the Committee will make specific recommendations regarding policies for the future.

The S-Area Defense Waste Processing Facility (DWPF) can process all of the high level radioactive wastes currently stored at the Savannah River Site with negligible risk of nuclear criticality. The characteristics which make the DWPF critically safe are: (1) abundance of neutron absorbers in the waste feeds; (2) and low concentration of fissionable material. This report documents the criticality safety arguments for the S-Area DWPF process as required by DOE orders to characterize and to justify the low potential for criticality. It documents that the nature of the waste feeds and the nature of the DWPF process chemistry preclude criticality.

A computer model of a Kearney and Tracker (K and T) Milwaukee Matic 600 (MM600) with a Gemini controller for use under the Deneb Robotics, Inc. simulation environment has been constructed. The simulation uses the K and T controller and standard MM600 machine geometry. Both the machine geometry and the controller are provided. The machine has been constructed using K and T`s standard machine dimensions and setup. The controller simulation addresses the most typically used NC codes, but may not be setup for extremely specialized functions. The machine geometry has been reduced to simulate only those components and surfaces which could possibly interfere or collide with other machine components or the workpiece envelope. The level of detail has been reduced to a functional level to enhance computational performance during simulation. The model may be directly used in the Virtual-NC environment for a complete machining simulator, or the model with kinematics may be used in IGRIP. The geometry is suitable for translation into standard file formats for importation into other systems.
