Contaminant Stabilization Technology Gap Report
- Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)
After an intentional radiological release or nuclear power plant (NPP) accidental release, there may be a large area that is contaminated. Re-suspension and tracking of contamination may create issues with containing the contaminated area and create additional exposure to responders. There is a need for technologies/methodologies to reduce resuspension and tracking. Current radiological particle containment relies on securing the area, setting up a single egress and ingress route, and minimizing the amount of contaminated equipment and vehicles leaving the contaminated zone. The re-suspension and tracking of contamination greatly hampers the ability to conduct first response activities in that zone therefore technologies that can reduce these spreading mechanisms are needed. In the NPP decommissioning industry, coatings are employed to reduce the spread of contamination. These coatings may not be readily available in the quantities needed for early response. Responders need containment methodologies that can be employed with existing equipment and materials on site using techniques such as fire hosing, street sweepers, and painting. A review by Parra et al. (2009) provided a good overview of fixative/stabilization materials, which formed the basis (in addition to a literature search) for a list of potential technologies presented to stakeholders in the initial stages of this work. Advantages and disadvantages were identified for each of the technologies, which were grouped into tiers based on the time-frame they would be available following a radiological release. Stakeholders then ranked containment technologies in terms of their preference and interest in use and availability. The final part of this task is to gather more information on the stakeholder-selected technologies and identify technical gaps that need to be filled with experimental research before technical procedures can be developed for containment technology use in the field.
