Good housekeeping: Safety and order in the scientific laboratory

Description: Laboratory safety might not seem, at first, to be very profoundly related to scientific knowledge. Of course safety is a relatively trivial issue in many scientific settings, especially in comparison to the kind of safety concerns found, say, at a construction site or a chemical plant. However, as scientific work has come to involve more exotic chemicals, biological organisms, and forms of radiation, and generally become more industrial in character, safety has become more of a concern. This has occurred alongside a general expansion of government regulation of workplace safety during the 20thc entury, and a recent trend toward extending work lace safety efforts to new kinds of work, including administrative and professional tasks. As a result of these trends, scientists find that they are increasingly being held responsible for following safety regulations in their re{approx}earc

Supporting evaluation for the proposed plan for final remedial action for the groundwater operable unit at the chemical plant area of the Weldon Spring Site, Weldon Spring, Missouri.

Description: This report presents the technical information developed since the interim record of decision (IROD) was issued in September 2000 (U.S. Department of Energy [DOE] 2000). The information was incorporated into the evaluation that was performed in selecting the preferred alternative for the Chemical Plant groundwater operable unit (GWOU) of the Weldon Spring site. The contaminants of concern (COCs) in groundwater and springs are trichloroethylene (TCE), nitrate, uranium, and nitroaromatic compounds. The preferred alternative of monitored natural attenuation (MNA) coupled with institutional controls (ICs) and contingency activities is described in the ''Proposed Plan (PP) for Final Remedial Action for the Groundwater Operable Unit at the Chemical Plant Area of the Weldon Spring Site, Weldon Spring, Missouri'' (DOE 2003b).

St. Charles County Weldon Spring citizens commission communication education project overview for 1995. Annual report, October 1, 1994--September 30, 1995

Description: The Weldon Spring DOE grantee, St. Charles County, is seeking an early renewal on the Weldon Spring Grant order to match the grant`s reporting calendar with the County`s fiscal calendar which is January through December. Therefore, this renewal application will cover five months time instead of 12 months. This notified annual overview bridges a two month period that precedes the appointment and activation of the Weldon Spring Citizens Commission in February 1995. In the original grant application the County described its intent to select a volunteer Citizens Oversight Commission to monitor the cleanup activities at the DOE`s Weldon Spring Site. This commission would serve at the County`s watchdog group by monitoring Weldon Spring Site activities and provide on-going communication to the County`s residents through publications and forums. The first eight months of the project involved setting up the project office and working with a three member {open_quotes}Section Panel/Work Group{close_quotes} to select the Citizen`s Commission. These activities were coordinated by a Project Director hired by the County and funded from the initial grant funds.

Maximum allowable heat flux for a submerged horizontal tube bundle

Description: For application to industrial heating of large pools by immersed heat exchangers, the so called maximum allowable (or critical) heat flux is studied for unconfined tube bundles aligned horizontally in a pool without forced flow. This is the condition at which vapor blanketing is expected to be initiated. Phenomenological considerations demonstrate why the maximum allowable heat flux would be expected to be less than for single tubes. Hydrodynamic theory is applied to extend the results of Lienhard and Dhir to large submerged bundles and the consequent correlation is compared to the correlation of Palen and Small and the limited data available for saturated conditions. To date the main conclusion is that estimates of q{double_prime}{sub chf} are highly uncertain for this configuration.

Weldon Spring citizens commission overview for 1996. Annual report, October 1, 1995--September 30, 1996

Description: The Weldon Spring DOE grantee, St. Charles County, is seeking a twelve month renewal of the Weldon Spring Grant to cover calendar year 1997. This annual overview provides a brief historical account of the Weldon Spring Citizen Commission`s origins as well its` activities and accomplishments i calendar year 1996. In late January of 1995, the St. Charles County Executive appointed seven St. Charles County residents to be members of the Weldon Spring Citizens Commission, an oversite committee for the U.S. Department of Energy`s Weldon Spring site Remedial Action Project (WSSRAP). The seven appointed Commission members were selected by the three member Selection Panel/Work Group. This group consisted of one member selected by each of the following: The DOE, St. Charles County Executive, and the St. Charles County Council. The end of the first year an agreement was reached between the Citizens Commission, the County Administration and the DOE that support of the Commissions activities for the upcoming year did not require the services of a full time project director. With the contracting of part time administrative assistance in April of 1996, the communications, office management, and financial management capabilities of the Commission have seen tremendous improvements. These improvements have enabled the Commission to spend more of their energy on fulfilling their oversite responsibilities. A overview of these activities and accomplishments are presented in the next section.

Partial control of complex processing systems. Progress report, May 15, 1992--September 14, 1993

Description: The past year saw substantial advances in the development of a model of Fluidized Catalytic Crackers, which now allows one to calculate both steady state and dynamic behavior of the system as basis for control studies. The first goal was to elucidate nonlinear features using the model. The model shows that adding a combustion promoter that catalyzes the CO-CO{sub 2} reaction reduces chances for multiple steady states within the range of desirable operating conditions; by adding enough promoter, one can also eliminate them. Conventional control structure can lead to input multiplicities.

From work plan to rod and beyond: Lessons learned on regulatory issues at the Weldon Spring Site

Description: Compliance with applicable or relevant and appropriate requirements (ARARs) is a key element of successful cleanup activities at environmental restoration sites. A number of ARAR issues were raised during the, planning, assessment, and implementation of restoration activities at a US Department of Energy (DOE) mixed waste site in Missouri. Resolutions were developed for issues ranging from storage time requirements to land disposal restrictions. This paper discusses ARAR issues and resolutions.

Modeling for process control. Progress report

Description: Significant developments have taken place in the control field during the last decade but their impact on industrial control practice has fallen far short of their full potential. One key difficulty that stands in the way of these new techniques is the need for process models. Work to be carried out under this grant aims at the development of a broad range of novel modeling and identification techniques which specifically address both information requirements of the new control analysis and design tools as well as the needs of the practicing control engineer.

Simulation of a Batch Chemical Process Using Parallel Computing with PVM and Speedup

Description: Speedup, a commercial software package for the dynamic modeling of chemical processes, has been coupled with the PVM software to allow a single process model to be distributed over several computers running in parallel. As an initial application, this coarse distribution technique was applied to a batch chemical plant containing 16 unit operations. Computation time for this problem was reduced by a factor of 4.7 using only three parallel processors in the UNIX computing environment. Better than linear acceleration was achieved from the significant reduction in computation required to reinitialize the smaller subprocesses at discontinuities in the solution. The process was physically divided at points that naturally separated the overall plant into distinct subprocesses. This facilitated the computation by minimizing the interconnection between the parallel units. Techniques were developed to make efficient material and energy transfers between the modeled subprocesses based on actual material transfers used in plant operations.

Miniature Nuclear Magnetic Resonance Spectrometer For In-Situ And In-Process Analysis And Monitoring

Description: The main purpose of this research is to develop a nuclear magnetic resonance (NMR) spectrometer that is small enough to be held in the palm of a hand. Such an instrument could be used in many applications of importance to DOE as well as to industry. These applications would include in-field characterization of contaminants, monitoring and analysis of chemical processes in chemical plants and other environmental monitoring applications. In addition to having drastically reduced size and cost, a miniature NMR instrument would be ideally suited for chemical analysis of volume limited samples which frequently occur in biological, medical and drug development applications.
