Technology Assessment of Dust Suppression Techniques Applied During Structural Demolition

Hanford, Fernald, Savannah River, and other sites are currently reviewing technologies that can be implemented to demolish buildings in a cost-effective manner. In order to demolish a structure properly and, at the same time, minimize the amount of dust generated from a given technology, an evaluation must be conducted to choose the most appropriate dust suppression technology given site-specific conditions. Thus, the purpose of this research, which was carried out at the Hemispheric Center for Environmental Technology (HCET) at Florida International University, was to conduct an experimental study of dust aerosol abatement (dust suppression) methods as applied to nuclear D and D. This experimental study targeted the problem of dust suppression during the demolition of nuclear facilities. The resulting data were employed to assist in the development of mathematical correlations that can be applied to predict dust generation during structural demolition

Thus, the purpose of this research, which was conducted by the Hemispheric Center for Environmental Technology (HCET) at Florida International University (FIU), was to perform an experimental study of dust aerosol abatement (dust suppression) methods as applied to nuclear D and D. This experimental study specifically targeted the problem of dust suppression during demolition. The resulting data were used in the development of mathematical correlations that can be applied to structural demolition. In the Fiscal Year 1996 (FY96), the effectiveness of different dust suppressing agents was investigated for different types of concrete blocks. Initial tests were conducted in a broad particle size range. In Fiscal Year 1997 (FY97), additional tests were performed in the size range in which most of the particles were detected. Since particle distribution is an important parameter for predicting deposition in various compartments of the human respiratory tract, various tests were aimed at determining the particle size distribution of the airborne dust particles. The effectiveness of dust suppressing agents for particles of various size was studied. Instead of conducting experiments on various types of blocks, it was thought prudent to carry out additional tests on blocks of the same type. Several refinements were also incorporated in the test procedures and data acquisition system used in FY96

Decision Analysis Modeling for Application and Fielding Selection Applied to Concrete Decontamination Technologies

The purpose of this two-year investigation is to field test innovative technologies for coating and surface removal on concrete floors and compare the compiled data to baseline technologies, thereby ensuring that the best and most cost-effective options are developed and subsequently used during the decontamination and decommissioning (D and D) of U.S. Department of Energy Environmental Management (DOE-EM) sites. Comprehensive and comparable data will be collected in the areas of health and safety, operations, and secondary waste management. The technologies tested will include DOE-EM funded technologies and commercial non-nuclear technologies that have the potential to meet the environmental restoration objectives. This report summarizes the activities performed during Fiscal Year 1996 (FY96) and describes the planned activities for Fiscal Year 1997 (FY97). Accomplishments for FY96 include the completion of preparatory work to begin field testing of innovative technologies. A total of seven technologies will be tested during FY97. As a part of this project, interactive computer software will be developed during FY97, allowing site-specific parameters and technology performance data to be considered when determining the best option given site-specific conditions
