This is the 300-area liquid effluent facilities computer software configuration management plan.

The scope of this design requirements document is to identify the functions and associated requirements that must be performed to accept, transport, handle, and store immobilized low-activity waste produced by the privatized Tank Waste Remediation System treatment contractors. The functional and performance requirements in this document provide the basis for the conceptual design of the Tank Waste Remediation System Immobilized low-activity waste interim storage facility project and provides traceability from the program level requirements to the project design activity.

The concept to use a slab as active element, working in zig-zag geometry, and also as Fresnel rhomb, seems to be rather attractive. However, in this case different depolarization effects in active element arc of crucial importance. We have carried out the estimations of depolarization effects arising both due to mechanical loading of an active element at its fastening and due to thermooptical distortions. To check up these rigid requirements to depolarization (0.1 % - 0.01 %) careful measurements of depolarization effects and their sources are being carried out. Mechanical loading gives one of the main contributions in depolarization at fastening of active element. Using model experiments with glass Fresnel rhomb under mechanical loading we have measured depolarization effects. It is proposed to use additional glass plate to compensate beam depolarization in zig-zag slab. The received results allow to expect successful use of the slab amplifier as a Fresnel rhomb providing rather high quality of optical material of active clement.

This report provides a summary of the radiological surveys performed in support of the near-facility environmental monitoring program at the Hanford Site.

The spheromak is a Magnetic Fusion Energy (MFE) configuration, which is a leading alternative to the tokamak. It has a simple geometry which offers an opportunity to achieve the promise of fusion energy if the physics of confinement, current drive, and pressure holding capability extrapolate favorably to a reactor. Recent changes in the US MFE program, taken in response to budget constraints and programmatic directions from Congress, include a revitalization of an experimental alternative concept effort. Detailed studies of the spheromak were consequently undertaken to examine the major physics issues which need to be resolved to advance it as a fusion plasma, the optimum configuration for an advanced experiment, and its potential as a reactor. As a result of this study, we conclude that it is important to evaluate several physics issues experimentally. Such an experiment might be appropriately be named the Sustained Spheromak Physics Experiment (SSPX). It would address several critical issues, the solution to which will provide the physics basis to enable an advanced experiment. The specific scientific goals of SSPX would be to: * Demonstrate that electron and ion temperatures of a few hundred electron volts can be achieved in a steady-state spheromak plasma sustained by a …

The purpose of this report is to highlight an area of contracting that requires Departmental attention to ensure that only reasonable and allowable costs are reimbursed for contractor employee relocation and temporary living costs. The Office of Inspector General issued nine audit reports over the past 5 years that identified almost $13.6 million of unreasonable or unallowable charges by contractors for employee relocation and temporary living costs. The absence of adequate controls to limit reimbursements to reasonable and allowable amounts was primarily caused by either vague contractual provisions or contractual provisions that were not consistent with the FAR or DEAR. The result has been that contractors were reimbursed for employee relocation and temporary living costs for which they were not entitled. Because of the sizable number of contractor changes in process and anticipated and the related relocation of contractor employees, we believe the issues raised in the audit reports require the attention of the Department`s senior managers.

Reauthorizing the Superfund hazardous waste cleanup law is a top environmental priority in the 105th Congress, according to congressional leaders and the subcommittees with jurisdiction. The program has been accused of being slow, ineffective, and too expensive. Many feel its liability system is unfair. And the taxes that feed the Superfund trust fund expired on December 31, 1995.

This test plan specifies the requirements and conditions for the injection of tracer gases into twelve tanks. Of the twelve tanks only four have been assigned at this time.

Acceptance testing of the System Integration Equipment (SIE) at Hanford was performed in two stages. The first was inconclusive, and resulted in a number of findings. These finding. are summarized as part of this report. The second stage of testing addressed these findings, and performed full system testing per the approved test procedure. This report includes summaries of all testing, results and finding.. Although the SIE did not in some cases perform as required for plant operations, it did perform per the system specification. (These discrepancies were noted and are addressed elsewhere.) Following testing, the system was formaLLy accepted. Documentation of this acceptance is incLuded in this report.
