    Executive summary for comprehensive report Danger Lurks Below: The Threat to Major Water Supplies from US Department of Energy Nuclear Weapons Testing . The bulk of the report lives with the Alliance for Nuclear Accountability Records, archived in the Swathmore College Peace Collection. This report details the serious shortfalls of the DOE\u27s cleanup program and shows how hazardous materials are migrating from nuclear weapons sites, placing the environment, water supply systems and significant numbers of people at risk. ANA, founded in 1987, is a national network of organizations that represents the concerns of communities near US nuclear weapons factories. It develops educational materials and advocates for safe solutions for the cleanup of the DOE nuclear weapons complex. We focus on the 13 largest DOE sites; however, it must be noted that many smaller DOE sites also need cleanup. This research was completed money allocated during Round 2 of the Citizens’ Monitoring and Technical Assessment Fund (MTA Fund). Clark University was named conservator of these works.

    Advanced Test Reactor Complex Facilities Radioactive Waste Management Basis and DOE Manual 435.1-1 Compliance Tables

    Get PDF
    U.S. Department of Energy Order 435.1, 'Radioactive Waste Management,' along with its associated manual and guidance, requires development and maintenance of a radioactive waste management basis for each radioactive waste management facility, operation, and activity. This document presents a radioactive waste management basis for Idaho National Laboratory's Advanced Test Reactor Complex facilities that manage radioactive waste. The radioactive waste management basis for a facility comprises existing laboratory-wide and facility-specific documents. U.S. Department of Energy Manual 435.1-1, 'Radioactive Waste Management Manual,' facility compliance tables also are presented for the facilities. The tables serve as a tool to develop the radioactive waste management basis

    The effect of blast-furnace slag particle size on the hydration of slag-Portland cement grouts at elevated temperatures

    The UK nuclear industry has historically used a unique specification of cement powder that differs from construction industry requirements. However, the slags that complied with this specification have become unavailable. The material now used to meet the requirements of the specification is a blend of standard construction industry ground granulated blast-furnace slag (GGBS), which has high fineness, with Calumite which is a coarser slag powder. Both materials have very similar chemical compositions, and the main reason for blending is to control the particle size distribution (PSD) to replicate the performance of the previous supply. The effect of changing the PSD on the performance properties of the cement paste was investigated. Isothermal conduction calorimetry at elevated temperatures was carried out to monitor the heat of hydration; it was found that the peak heat and total heat evolution increased with an increase in GGBS content. It was also found that Calumite contributes very little to the hydration reaction and thus behaves similarly to an inert filler. As the GGBS content was decreased, the fluidity of the pastes increased up to a certain point, but decreased again for systems dominated by very coarse particles, indicating that there is an optimum balance between the finer and coarser slag particles within this cementing system

    Analysis of the Institutional Framework for Radioactive Waste Management in Indonesia

    The analysis of the infrastructure for radioactive waste management in Indonesia has been studied using several parameters, i.e. policy, regulatory authorities and their regulations, implementing organizations and financial system. By considering the International trends and the Indonesian program to utilize nuclear power, the infrastructure of radioactive waste management needs to be improved. The Act No. 10/1997 on Nuclear Energy for the future beneficence will have to be amended to incorporate several missing key points on waste management, such as definition of radioactive waste, disposal of Low and Intermediate Level Waste (LILW), and classification of waste. Full involvement of some important stakeholders, especially the State Ministry of Environment, on the radioactive waste management infrastructure is required since some radioactive waste is generated from non nuclear waste. Assigning full authority to the State Ministry of Environment for regulating radioactive waste generated by non nuclear facilities may be more effective, whereas BAPETEN is still holding onto control over the waste generated from nuclear facilities. In the near future, several regulations on clearance level, classification of waste, NORM/TENORM, and financial system are expected to be set up for urgent need. By considering the high risk for handling of radioactivity, including for transportation and storage, the liability or assurance of the safety for such activities must be accounted for. Finally, establishment of financial system for long term waste management in Indonesia needs to be implemented to ensure that the radioactive waste will not be the burden on future generations.Received: 21 April 2009; Revised: 18 August 2009; Accepted: 25 August 200

    Rural communities and awareness of DOE environmental management programs at the Nevada Test Site: Do outreach efforts matter?

    Full text link
    Are residents living in communities around the Nevada Test Site aware of environmental remediation activities and do outreach efforts contribute to awareness? Through a U.S. Department of Energy (DOE) grant, the University of Nevada, Las Vegas administered a mail questionnaire to 14,083 residents and received 1,721 responses. Approximately 90% of the respondents reported awareness of past nuclear tests at the Nevada Test Site; 63% reported awareness of low-level radioactive waste disposal at the site; and 41% are aware that the Yucca Mountain Project for high level waste disposal is part of the Office of Civilian Radioactive Waste Management and not part of the Office of Environmental Management. Using both logit and probit regression models, at a 1% level of significance, respondents who reported obtaining information from the Community Advisory Board for Nevada Test Site Programs are more likely to be knowledgeable about low-level radioactive waste disposal activities and are more likely to be knowledgeable that the missions of the Office of Environmental Management and Office of Civilian Radioactive Waste Management are different
