Reducing the Use of Highly Enriched Uranium in Civilian Research Reactors (2016)

Since 1978, U.S. policy and programs have sought to minimize or phase out the use of highly enriched uranium fuel in civilian research and test reactors around the world to prevent the misuse of the fuel to make nuclear weapons. Despite some progress, converting the remaining research reactors to less proliferation-prone low enriched uranium fuel has proven to be a slow process. This report identifies successes and challenges that remain in th... More >>

Fostering Transformative Research in the Geographical Sciences (2015)

Transformative research drives science forward by redefining entire fields of study, forming new research communities, and even launching new industries. Such research brings great rewards, but also carries risks for funding agencies that are challenged to identify, at their earliest stages, those projects that have the potential to yield transformative results. By reviewing how transformative research emerged in the past, the report identifie... More >>

Using Graywater and Stormwater to Enhance Local Water Supplies: An Assessment of Risks, Costs, and Benefits (2015)

Graywater and stormwater capture and use can expand local water availability while providing additional benefits, such as reduced water pollution (for stormwater) and a drought-resistant year-round water supply (for graywater). Treatment can help address contaminants in the water, but a lack of risk-based treatment guidelines hinders the broader use of stormwater and graywater, this report finds. There is no single best way to use graywater o... More >>

Affordability of National Flood Insurance Program Premiums: Report 2 (2015)

Drawing on lessons learned from a proof-of-concept analysis, this report proposes that the Federal Emergency Management Agency develop a microsimulation model--which will use a database of records for individual policyholders and property owners to mimic how policy decisions might affect those individuals--to simulate the effects of different National Flood Insurance Program affordability policy options. The report also notes, however, that som... More >>

Spills of Diluted Bitumen from Pipelines: A Comparative Study of Environmental Fate, Effects, and Response (2015)

The U.S. Department of Transportation (DOT) needs to modify its regulations and planning in order to strengthen preparedness for accidental spills of diluted bitumen from pipelines. Diluted bitumen is a type of crude oil made from bitumen extracted from tar sands. While immediately following a spill, diluted bitumen behaves similarly to other crude oils, exposure to the environment induces rapid physical and chemical changes known as "weathering... More >>
