book coverSevere Space Weather EventsUnderstanding Societal and Economic Impacts: A Workshop Report   (SSB)
Released 2008-12-17

The adverse effects of extreme space weather on modern technology--power grid outages, high-frequency communication blackouts, spacecraft anomalies--are well known and well documented, and the physical processes underlying space weather are also generally well understood. Less well documented and understood, however, are the potential economic and societal impacts of the disruption of critical technological systems by severe space weather. As a first step toward determining the socioeconomic impacts of extreme space weather events and addressing the questions of space weather risk assessment and management, a public workshop was held in May 2008. The workshop brought together representatives of industry, the government, and academia to consider both direct and collateral effects of severe space weather events, the current state of the space weather services infrastructure in the United States, the needs of users of space weather data and services, and the ramifications of future technological developments for contemporary society's vulnerability to space weather. The workshop concluded with a discussion of un- or underexplored topics that would yield the greatest benefits in space weather risk management.

book coverReview and Assessment of Developmental Issues Concerning the Metal Parts Treater Design for the Blue Grass Chemical Agent Destruction Pilot Plant   (BAST)
Released 2008-03-26

The United States is in the process of destroying its chemical weapons stockpile. In 1996, Congress mandated that DOD demonstrate and select alternative methods to incineration at the Blue Grass and Pueblo sites. The Assembled Chemical Weapons Alternatives (ACWA) program was setup to oversee the development of these methods, and pilot plants were established at both sites. One of the new technologies being developed at the Blue Grass pilot plant are metal parts treaters (MPTs) to be used for the empty metal munitions cases. During recent testing, some issues arose with the MPTs that caused the ACWA to request a review by the NRC to investigate and determine their causes. This book presents a discussion of the MPT system; an assessment of the MPT testing activities; an analysis of thermal testing, modeling, and predicted throughput of the MPT; and an examination of the applicability of munitions treatment units under development at Pueblo for the Blue Grass pilot plant.
