Microstructural and solidification cracking evaluation of electron beam welds in 304L

Description: Weld hot cracking of stainless steels is a major materials-related problem in the welding industry. This present investigation evaluates the crack susceptibility of highly-constrained EB welds made in materials whose DeLong ferrite potentials range from zero to nine FN. In addition, the effect of piece part strength level on cracking is examined. This study has revealed that these deep penetration EB welds have regions that solidify as primary austenite, even when the DeLong ferrite potential i… more

Meteorological conditions during the winter validation study at Rocky Flats, Colorado: An overview

Description: The objective for the Winter Validation Study was to gather field data for validation of the Terrain-Responsive Atmospheric Code (TRAC) under winter time meteorological conditions. Twelve tracer tests were conducted during a two-week period in February 1991. Each test lasted 12 hours, with releases of SF{sub 6} tracer from the Rocky Flats Plant near Golden, Colorado. The tests included ground-based and airborne sampling to 16 km from the release point. This presentation summarizes meteorologica… more

EG G sampling program results FY 1989

Description: Thirty-three waste drums were returned to Rocky Flats in support of EG G Idaho's quality control program for the Stored Waste Examination Pilot Plant. The drums were opened and examined in the size reduction facility at the Rocky Flats Plant. Contents of each drum were consistent with the Item Description Codes; however, four sludge drums and one combustible drum contained free liquids. These five drums failed to meet the Waste Isolation Pilot Plant and the Department of Transporation criteria.… more

Application of molten salts in pyrochemical processing of reactive metals

Description: Various mixes of chloride and fluoride salts are used as the media for conducting pyrochemical processes in the production and purification of reactive metals. These processes generate a significant amount of contaminated waste that has to be treated for recycling or disposal. Molten calcium chloride based salt systems have been used in this work to electrolytically regenerate calcium metal from calcium oxide for the in situ reduction of reactive metal oxides. The recovery of calcium is charact… more

Isotopic ratio method for determining uranium contamination

Description: The presence of high concentrations of uranium in the subsurface can be attributed either to contamination from uranium processing activities or to naturally occurring uranium. A mathematical method has been employed to evaluate the isotope ratios from subsurface soils at the Rocky Flats Nuclear Weapons Plant (RFP) and demonstrates conclusively that the soil contains uranium from a natural source and has not been contaminated with enriched uranium resulting from RFP releases. This paper describ… more

Safety analyses performed in the Systematic Evaluation Program at Rocky Flats

Description: Structures, systems, and components (SSC) at Rocky Flats were designed and put into operation before current standards and criteria applicable to these SSCs were developed. The purpose of the Systematic Evaluation Program (SEP) at Rocky Flats (RF) is to systematically compare the design of SSCs to current design requirements and assess the differences to assure that a balanced and integrated level of safety is achieved to support long-term operation of the facilities. The SEP is being performed… more

A research study to determine the effect of Total Quality Management (TQM) on employee morale in Plant Procedures Division at EG&G, Rocky Flats, Inc.

Description: EG&G at Rocky Flats, Golden, Colorado, experienced a high amount of low morale, due to the plant site having been designated to close, and the uneasiness of the working force was very visible. Some employees accepted early retirement in October 1992, however, all received letters of 120 days notice in March 1993, and were advised several cuts Would be made by October 1, 1993. This information alone caused many insecurities in employees, and caused morale to decrease even more. This is an in dep… more

Recommended plutonium release fractions from postulated fires. Final report

Description: This report was written at the request of EG&G Rocky Flats, Inc. in support of joint emergency planning for the Rocky Flats Plant (RFP) by EG&G and the State of Colorado. The intent of the report is to provide the State of Colorado with an independent assessment of any respirable plutonium releases that might occur in the event of a severe fire at the plant. Fire releases of plutonium are of interest because they have been used by EG&G to determine the RFP emergency planning zones. These zones … more

An investigation of gas separation membranes for reduction of thermal treatment emissions

Description: Gas permeable membranes were evaluated for possible use as air pollution control devices on a fluidized bed catalytic incineration unit. The unit is a candidate technology for treatment of certain mixed hazardous and radioactive wastes at the Rocky Flats Plant. Cellulose acetate and polyimide membranes were tested to determine the permeance of typical off-gas components such as carbon dioxide, nitrogen, and oxygen. Multi-component permeation studies included gas mixtures containing light hydroc… more

Effect of internal heating during hot compression testing on the stress-strain behavior and hot working characteristics of Alloy 304L

Description: Temperature change from conversion of deformation to internal heat, and its effect on stress-strain behavior of alloy 304L was investigated by initially isothermal (temperature of specimen, compression dies, environment equilibrated at initiation of test) uniaxial compression. Strain rate was varied 0.01 s{sup {minus}1} to 1 s{sup {minus}1} (thermal state of specimen varied from nearly isothermal to nearly adiabatic). Specimens were deformed at 750 to 1150 to a strain of 1. Change in temperatur… more

On-site worker-risk calculations using MACCS

Description: We have revised the latest version of MACCS for use with the calculation of doses and health risks to on-site workers for postulated accidents at the Rocky Flats Plant (RFP) in Colorado. The modifications fall into two areas: (1) an improved estimate of shielding offered by buildings to workers that remain indoors; and, (2) an improved treatment of building-wake effects, which affects both indoor and outdoor workers. Because the postulated accident can be anywhere on plant site, user-friendly s… more

Magnetic adsorbents for actinide and heavy metal removal from waste water

Description: Magnetic adsorbents can be applied to the treatment of waste water in various physical forms. For example, barium ferrite (BaO{center_dot}Fe{sub 2}O{sub 3}) has been used successfully as powder, granules or pellets. Iron ferrite, or magnetite, a naturally occurring ore, can also be used in much the same manner. However, natural magnetic needs activation to have the same capacity as freshly prepared ferrite. Furthermore, ferrites have been used solely in a batch mode because of their finely divi… more

Risk perception on management of nuclear high-level and transuranic waste storage

Description: The Department of Energy`s program for disposing of nuclear High-Level Waste (HLW) and transuranic (TRU) waste has been impeded by overwhelming political opposition fueled by public perceptions of actual risk. Analysis of these perceptions shows them to be deeply rooted in images of fear and dread that have been present since the discovery of radioactivity. The development and use of nuclear weapons linked these images to reality and the mishandling of radioactive waste from the nations militar… more
