U.S. Department of Energy Portsmouth Annual Site Environmental Report (ASER) for 2012. Student Summary

The report that follows is a summary of the U.S. Department of Energy Portsmouth Annual Site Environmental Report for 2012 (ASER), regarding PORTS located near Piketon, Ohio. The summary has been compiled by the 2015 WHS Environmental Science class, made up of juniors and seniors at WHS during the 2014-2015 school year. Even with most of the class having lived in this region for their entire lives, it became apparent how little of the workings of the plant were known by the members of the class. In the process of putting this summary together, we were able to gain a better understanding of the history, function, and possible future of the site. The presentations provided by Ohio University, Fluor-B&W Portsmouth LLC (FBP), U.S. DOE, and Rio Grande University were greatly appreciated and provided invaluable understanding of the materials which we were asked to summarize. Not only did we learn from the presentations, but we greatly enjoyed the opportunities to participate in the field studies that gave us a glimpse into what is being done at the plant site to ensure the environmental safety of people and wildlife of this region. Our goal from this summary has been to make the information concerning the monitoring and cleanup of the PORTS facility better understood by the people who it most affects. We hope that this summary makes the information useful to you and that you can gain a better understanding of the cleanup processes that are going on around the site to ensure your safety. Though it has been hard work, we appreciate the opportunity that we have been presented with to learn and share with the people of our community.

Confined Space Evaluation Student Manual, #19613

Many workplaces contain spaces that are considered to be “confined” because their configuration hinders the activities of employees who must enter into, work in, and exit from them. In general, the permit-required confined spaces (PRCSs) Occupational Safety and Health Administration (OSHA) standard requires that Los Alamos National Laboratory (LANL) evaluate the workplace to determine if any spaces are PRCSs. The standard specifies strict procedures for the evaluation and atmospheric testing of a space before and during an entry by workers. The OSHA PRCS standard provides for alternative (less stringent than full-permit) entry procedures in cases where the only hazard in a space is atmospheric and the hazard can be controlled by forced air. At LANL, all confined spaces or potential confined spaces on LANL-owned or -operated property must be identified and evaluated by a confined space evaluator accompanied by a knowledgeable person. This course provides the information needed by confined space evaluators to make judgements about whether a space is a confined space, and if so, whether the space will require a permit for entry.

Community Anaerobic Digester: Powered by Students and Driving Practical Applications

The Vermont Tech Community Anaerobic Digester (VTCAD) was conceived and funded by a partnership of educational, agricultural, waste management and environmental groups to create a living laboratory demonstrating the value of recycling nutrients, renewable energy and agricultural co-products from organic wastes. VTCAD was constructed on the Randolph Center, Vermont campus of Vermont Tech, a public college offering engineering technology, agricultural, renewable energy education and workforce training. With funding from the U.S. Department of Energy (DOE), the Vermont State Colleges and others, construction was completed in early 2014 and the facility has been operational since April 2014. At full power, VTCAD uses 16,000 gallons of manure and organic residuals to produce 8,880 kilowatt hours (kWh) of electricity per day, ‘waste’ heat that will be used to heat four campus buildings, bedding material for the college dairy herds and recycled nutrients used as crop fertilizer. VTCAD uses a mixture of manure from co-managed farms and organic residuals collected from the community. Feedstock materials include brewery residuals, the glycerol by-product of biodiesel production from waste cooking oil, grease trap waste, and waste paper and, soon, locally collected pre- and post-consumer food residuals.

Student Summary of the U.S. Department of Energy Portsmouth Annual Site Environmental Report (ASER) for 2014

The purpose of the full ASER document is to provide details of environmental activities, primarily environmental monitoring, for calendar year 2014. This summary report of the full 2014 ASER provides details in which DOE demonstrates compliance with local, state and federal regulations within environmental programs - both radiological and non-radiological monitoring and groundwater monitoring (DOE, 2016). This report is not intended to present all of the monitoring activities at PORTS and more information can be found at the PORTS Environmental Information Center and website, which is http://energy.gov/pppo/portsmouth-environmental-center.

Mid-Award Progress Report for Department of Energy Office of Science Graduate Student Research Program

The purpose of the work proposed for this study is to investigate the behavior and transport mechanisms for cesium-137 in soils collected from contaminated sites with distinct source release scenarios. More specifically, this study aims to determine with which elements and minerals cesium-137 associates in these various environments to more reliably predict its migration in the subsurface. This will be achieved using a state-of-the-art analysis technique available at Lawrence Livermore National Laboratory (LLNL) known as NanoSIMS. Nano-scale secondary ion mass spectrometry, or NanoSIMS, is a destructive surface analysis technique in which positive secondary ions are generated from the surface of a sample and then quantified based on their mass-to-charge ratio (m/z) using mass spectrometry. The data collected about the secondary ions can then be used to create isotope-specific spatial maps with a resolution of a few hundred nanometers and depth profiles that show the variation of the secondary ion intensity with sputtering time. This should be an ideal technique for locating cesium-137 in a sample, as cesium is an easily ionized element, meaning the yield of secondary cesium (Cs) ions produced should be high and making the identification of cesium-137 straight forward.
