book coverReview of International Technologies for Destruction of Recovered Chemical Warfare Materiel   (BAST)
Released 2006-11-02

The Chemical Weapons Convention requires, among other things, that the signatories to the convention--which includes the United States--destroy by April 29, 2007, or as soon possible thereafter, any chemical warfare materiel that has been recovered from sites where it has been buried once discovered. For several years the United States and several other countries have been developing and using technologies to dispose of this non-stockpile materiel. To determine whether international efforts have resulted in technologies that would benefit the U.S. program, the U.S. Army asked the NRC to evaluate and compare such technologies to those now used by the United States. This book presents a discussion of factors used in the evaluations, summaries of evaluations of several promising international technologies for processing munitions and for agent-only processing, and summaries of other technologies that are less likely to be of benefit to the U.S. program at this time.

book coverReview and Assessment of the Health and Productivity Benefits of Green Schools: An Interim Report   (BICE)
Released 2006-02-06

Some educational professionals have suggested that so-called green schools would result in superior performance and increased health for students and teachers. While there is no commonly accepted definition of a green school, there are a number of attributes that such schools appear to have: low cost operations, security, healthy and comfortable, and an environment that enhances learning are among them. To determine the health and productivity benefits of green schools, the Massachusetts Technology Collaborative, the Barr and Kendall Foundations, the Connecticut Clean Energy Fund, and the U.S. Green Building Council asked the NRC to examine available studies about the effects of green schools on student learning and teacher productivity. This interim report presents an evaluation of evidence for relationships between various health, learning, and productivity outcomes and five characteristics of green schools: the building envelope, ventilation, lighting, acoustics, and condition. The final report will present evaluations for additional characteristics, a synthesis of the results of all assessments, and promising areas of research.

book coverReview and Assessment of the Proposals for Design and Operation of Designated Chemical Agent Destruction Pilot Plants (DCAPP-Pueblo): Letter Report   (BAST)
Released 0000-00-00

n 2002, the Army asked for proposals for a full-scale pilot plant to destroy chemical weapons at the Pueblo Chemical Depot and, in 2003, for a similar plant for the Blue Grass Army Depot. In both cases, the initial designs proved to be too costly, and redesigns were requested. At the same time, the Army asked the NRC to form committees to review and assess these proposals. This report focuses on the technical aspects, maturity, and schedule of the proposed modified design for the Pueblo facility.

book coverReview and Assessment of the Proposals for Design and Operation of Designated Chemical Agent Destruction Pilot Plants (DCAPP-Blue Grass II): Letter Report   (BAST)
Released 0000-00-00

In 2002, the Army asked for proposals for a full-scale pilot plant to destroy chemical weapons at the Pueblo Chemical Depot and, in 2003, for a similar plant for the Blue Grass Army Depot. In both cases, the initial designs proved to be too costly, and redesigns were requested. At the same time, the Army asked the NRC to form committees to review and assess these proposals. This report focuses on the technical aspects, maturity, and schedule for the proposed full intermediate design for the Blue Grass facility, less the supercritical water oxidation process, which was reviewed in a previous report.

book coverLetter Report of Review and Assessment of the Proposals for Design and Operation of Designated Chemical Agent Destruction Pilot Plants (DCAPP-Blue Grass)   (BAST)
Released 2006-07-11

In 2003, the Army asked for proposals for a full-scale pilot plant to destroy chemical weapons at the Blue Grass Army Depot using a neutralization process. The initial proposal from Bechtel and Parsons Corporations, using a supercritical water oxidation process (SCWO), proved to be too costly, so the Army asked for a revised proposal. At the same time, the Army asked the NRC to form committees to review and assess this proposal along with one developed for the chemical weapon storage facility in Pueblo, CO. This letter report provides an assessment of the intermediate design proposal of the modified SCWO Blue Grass Chemical Agent Destruction Pilot Plant. The assessment is confined to the technical aspects, maturity, and schedule of the proposed facility.
