By National Research Council, Division on Engineering and Physical Sciences, Board on Army Science and Technology, Committee on Review and Evaluation of Alternative Technologies for the Demilitarization of Assembled Chemical Weapons: Phase II

The software supervisor for Assembled Chemical guns review (PMACWA) of the dept of safeguard (DOD) asked the nationwide examine Council (NRC) to evaluate the engineering layout reviews (EDSs) constructed through Parsons/Honeywell and common Atomics for a chemical demilitarization facility to totally cast off the assembled chemical guns on the Pueblo Chemical Depot in Pueblo, Colorado. to complete the duty, the NRC shaped the Committee on evaluate and review of other applied sciences for Demilitarization of Assembled Chemical guns: section II (ACW II Committee). This document provides the result of the committee's medical and technical evaluate, so one can help the place of work of the Secretary of protection in identifying the expertise package deal for destroying the chemical munitions at Pueblo.

The committee evaluated the engineering layout applications proposed via the know-how services and the linked experimental stories that have been played to validate unproven unit operations. an important a part of the trying out software concerned increasing the expertise base for the hydrolysis of full of life fabrics linked to assembled guns. This approach was once a priority expressed via the Committee on evaluate and assessment of other applied sciences for Demilitarization of Assembled Chemical guns (ACW I Committee) in its unique file in 1999 (NRC, 1999). the current examine came about because the experimental reviews have been in growth. every now and then, checks for the various aiding unit operations weren't accomplished in time for the committee to include effects into its evaluate. In these circumstances, the committee pointed out and mentioned power troublesome areas in those operations. according to its services and its competitive data-gathering actions, the committee used to be capable of behavior a accomplished evaluate of the try out information that have been accomplished for the final process layout. This document summarizes the study.

Hydrologic Analysis and Design (2nd Edition)

Real-world in standpoint, this ebook deals an applications-oriented creation to engineering research and layout tools which are on the topic of numerous parts of the hydrologic cycle, in particular city hydrology. The publication explores the actual methods of the hydrologic cycle, t he computational basics of hydrologic research, and the weather of layout hydrology.

Social Perspectives on the Sanitation Challenge

If the objective is to part the variety of humans with out sustainable entry to secure ingesting water and simple sanitation via 2015, we would possibly not merely desire new applied sciences yet quite leading edge sanitation suggestions, new instruments for decision-making and an figuring out of various stakeholder views alongside the sanitation chain.

Environmental Management of Concentrated Animal Feeding Operations (CAFOs)

Fresh and environmentally sound disposal of animal waste within the amounts that centred Animal Feeding Operations (CAFOs) produce can simply be defined as a problem. Designed to supply useful info, Environmental administration of centred Animal Feeding Operations (CAFOs) covers the techniques and practices excited about the operation and upkeep of CAFOs, paying specific cognizance to regulatory standards and compliance and top to be had expertise (BAT) practices.

However, major concerns for each technology package remained, including the adequacy of secondary treatment of agent hydrolysates and the primary and secondary treatment of energetic materials contained in the chemical weapons. In September 1999, the PMACWA requested that the tenure of the committee be extended to review the results of the Demonstration I tests. The committee was asked to determine if and how the results affected the committee’s commentary, findings, and recommendations, as well as the recommended steps required for implementation provided in the initial report.

3,000 to 30,000) that do not appear to be energetic (as evaluated by a simple hammer test) but may present other problems in subsequent processing steps. For example, because they are viscous, they might clog pumps or pipes. Also, they might separate from the aqueous phase of the hydrolysate and affect the reaction time for complete hydrolysis. The researchers at LANL recognize the concerns of the ACW I Committee about the formation of picric acid in the presence of lead, particularly the lead stearate in the M28 propellant, which could lead to the formation of lead picrate, a very sensitive explosive (Bishop, 2000).

Thus, the RDX particle size does not depend on the size of the Composition B pieces fed into the reactor but on the size of the original RDX particles mixed into the TNT, typically between 10 µm and 1 mm. The particle distribution may be skewed toward the larger particles because the smaller particles dissolve more rapidly in the TNT. 1This information can also be found in condensed form in Appendix E of the initial ACW I Committee report (NRC, 1999). 2Composition B contains 1 percent wax. Depending on the nature of the wax, some long-chain fatty acids may be present, which act as surfactants.
