This Design Criteria Document provides the criteria for design and construction of electrical system modifications for 100K Area that are essential to protect the safe operation and storage of spent nuclear fuel in the K-Basin facilities.

A criticality safety review is presented for the use of two portable NDA detectors from Los Alamos during an IAEA inspection of the SNM at PFP. The units are an Active Well Coincidence Counter (AWCC) and a High Level Neutron Coincidence Counter (HLNCC). Approval for their employment is based on the inherent safety of the containers to be assayed, one at a time, and because their designs conform with the acceptability criteria which allow the other NDA detectors currently employed at the facility.

The HC-21C thermal stabilization process stabilizes reactive plutonium bearing material for long term storage. A Loss On Ignition (LOI) analysis is performed on all materials that are stabilized in the muffle furnaces prior to being stored in the vaults to ensure suitability for vault storage. The material is required to have a LOI of less than 1% (OSD-184-00013 Limit). The LOI analysis is performed to assure that all volatiles that could potentially pressurize the sealed containers over long periods of time, like water, have been removed. It is possible, while performing LOI analysis to see a Gain On Ignition (GOI) due to additional oxidation of materials. In the current stabilization campaign, two items processed have had a positive LOI or GOI result. One concern with a GOI is that the weight gain may actually be masking a weight loss. (Reference 15530-94-WSL-156). Other concerns with a GOI result are that the removal of the oxygen could create a vacuum in the product can causing it to collapse during long term storage or the oxidation of material would increase the volume of the solids potentially bulging or rupturing the product container. In the past, GOIs have been seen on items that were …

We describe a fabrication process used to manufacture high power-to-weight-ratio flexible solar array modules for use on high-altitude-long-endurance (HALE) solar-electric unmanned air vehicles (UAVs). These modules have achieved power-to-weight ratios of 315 and 396 W/kg for 150{mu}m-thick monofacial and 110{mu}m-thick bifacial silicon solar cells, respectively. These calculations reflect average module efficiencies of 15.3% (150{mu}m) and 14.7% (110{mu}m) obtained from electrical tests performed by Spectrolab, Inc. under AMO global conditions at 25{degrees}C, and include weight contributions from all module components (solar cells, lamination material, bypass diodes, interconnect wires, and adhesive tape used to attach the modules to the wing). The fabrication, testing, and performance of 32 m{sup 2} of these modules will be described.

Version 1.485 of the GENII software was released by the PNL GENII custodian in December of 1990. At that time the WHC GENII custodian performed several tests to verify that the advertised revisions were indeed present and that these changes had not introduced errors in the calculations normally done by WHC. These tests were not documented at that time. The purpose of this document is to summarize suitable acceptance tests of GENII and compare them with a few hand calculations. The testing is not as thorough as that used by the PNL GENII Custodian, but is sufficient to establish that the GENII program appears to work correctly on WHC managed personal computers.

PYROGRAF-III{trademark} is a highly graphitic vapor grown carbon fiber (VGCF) produced by the chemical vapor deposition of carbon on metallic catalysts in the temperature range of 1000{degrees}C. This is entirely different from commercial carbon fiber, which is made by first forming a filament and then graphitizing it in a high temperature oven. For PYROGRAF-III{trademark} small amounts of sulfur in the form of hydrogen sulfide are added to the process to enhance the yield. This method of supplying the necessary sulfur is both expensive and hazardous since hydrogen sulfide is flammable, toxic, and corrosive. To supply the sulfur more economically and safely, high sulfur coal was proposed as a replacement for the hydrogen sulfide gas. Applied Sciences, Inc. is the sole producer of this material in pound quantities. The primary objective of research grant OCDO-922-8 was to demonstrate that Ohio`s high sulfur coal can replace the expensive, toxic hydrogen sulfide in the production of vapor grown carbon fiber as well as become a partial or complete source of carbon. The secondary objective was to analyze the exhaust for the release of harmful sulfur compounds and to project the economic potential of the use of coal.

Preliminary differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA) data were reported in a letter from K.L. Kocher, WHC, to G.D. Johnson; et. al, WHC, ``40 Day Deliverable for Tank 241-SY-103``, dated July 14, 1994. This report is the final report for the Sy-1-3 auger sample characterization effort; some of the data reported earlier may have changed. A copy of the hot cell work plan, chain of custody forms, extruded segment description sheets, and photographs of the extruded augers were also included in the cited letter. The final DSC, TGA, total organic carbon (TOC), and total inorganic carbon (TIC) data, and the DSC and TGA scans and analytical cards, are reported here.

A criticality safety review is presented for the use of plastic-sheet glovebags for the operations of draining demisters on the 26-inch vacuum system headers. A criticality drain is required because of the possibility for spilling liquid of sufficient volume and fissile content for criticality. It is recommended that the glovebag design include a rigid, 2ft {times} 2ft floor with a central drain feeding a geometrically favorable spill-catch vessel, plus a screen grid above the bottom for drain protection.

This document provides the test plan and procedures to certify and design verify the 42{double_prime} and 4{double_prime}-6{double_prime} Flexible Receiver as a safety class 3 system. The Flexible Receiver will be used by projects W-151 and W-320 for removing equipment from tanks C-106 and AZ-101.

The GENII program calculates doses from radionuclides released into the environment for a variety of possible exposure scenarios. The user prepares an input data file with the necessary modelling assumptions and parameters. The program reads the user`s input file, computes the necessary doses and stores these results in an output file. The output file also contains a listing of the user`s input and gives the title lines from the data libraries which are accessed in the course of the calculations. The purpose of this document is to provide users of the GENII software with the configuration controls which are planned for use by WHC in accordance with WHC-CM-3-10. The controls are solely for WHC employees. Non-WHC individuals are not excluded, but no promise is made or implied that they will be informed of errors or revisions to the software. The configuration controls cover the GENII software, the GENII user`s guide, the list of GENII users at WHC, and the backup copies. Revisions to the software must be approved prior to distribution in accordance with this configuration management plan.

This ATP establishes field testing procedures to demonstrate that the electrical/instrumentation system functions as intended by design for the Radioactive Mixed Waste Land Disposal Facility. Procedures are outlined for the field testing of the following: electrical heat trace system; transducers and meter/controllers; pumps; leachate storage tank; and building power and lighting.

For the next 30 years, the main activities at the Hanford Site will involve the handling and cleanup of toxic substances. Thousands of workers involved in these new activities will need systematic training appropriate to their tasks and associated risks. This project is an important part of the Hanford Site mission and will enable the US Department of Energy (DOE) to meet high standards for safety. The Hazardous Materials Management and Emergency Response Training Center (HAMMER) project will construct a centralized regional training center dedicated to training hazardous materials workers and emergency responders in classrooms and with hands-on, realistic training aids representing actual field conditions. The HAMMER Training Center will provide a cost-effective, high-quality way to meet the Hanford Site training needs. The training center creates a partnership among DOE; government contractors; labor; local, state, and tribal governments; and selected institutions of higher education.
