Energy density is only a necessary condition for usefulness as an energetic material. Detailed here is the final report of a search ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571478Twelve AFIP in-process foil samples, fabricated by either Y-12 or LANL, were shipped from LANL to PNNL for potential characterization using optical and scanning electron microscopy techniques. Of these twelve, nine different conditions were examined ...http://www.ntis.gov/search/product.aspx?ABBR=DE20131069212The earthquake and the tsunami that occurred in Japan on March 11, 2011 led to releases of radioactive materials from the Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Station into the environment. This report compares data, assumpti ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571634This report describes investigations directed toward understanding the extent of the presence of highly alkaline soluble, non-pertechnetate technetium (n-Tc) in the Hanford Tank supernatants. The goals of this report are to: (a) present a review of t ...http://www.ntis.gov/search/product.aspx?ABBR=DE20131069209Assessing the performance of Spent (or Used) Nuclear Fuel (UNF) in geological repository requires quantification of time-dependent phenomena that may influence its behavior on a time-scale up to millions of years. A high-level waste repository enviro ...http://www.ntis.gov/search/product.aspx?ABBR=DE20131069210The subject of graphite irradiation creep characteristics is of great interest to the nuclear industry. Designing experiments for graphite creep is problematic because of the very substantial dimensional evolutions that occur in the material during r ...http://www.ntis.gov/search/product.aspx?ABBR=DE20131068092The US Department of Energy (DOE) National Nuclear Security Administration (NNSA), Nevada Site Office (NSO), Environmental Managements Soils Activity has authorized the Desert Research Institute (DRI) to conduct field assessments of potential sedimen ...http://www.ntis.gov/search/product.aspx?ABBR=DE20131068014Potassium isotopic (K-41/K-39) compositions are notoriously difficult to measure. TIMS measurements are hindered by variable fractionation patterns throughout individual runs and too few isotopes to apply an internal spike method for instrumental mas ...http://www.ntis.gov/search/product.aspx?ABBR=N20120017926Assessing the performance of Spent (or Used) Nuclear Fuel (UNF) in geological repository requires quantification of time-dependent phenomena that may influence its behavior on a time-scale up to millions of years. A high-level waste repository enviro ...http://www.ntis.gov/search/product.aspx?ABBR=DE20131069211Alkali-rich igneous fragments were identified in the brecciated LL-chondrites, Kr henberg (LL5), Bhola (LL3-6) and Yamato (Y)-74442 (LL4), and show characteristic fractionation patterns of alkaline elements. The K-Rb-Cs-rich fragments in Kr henberg, ...http://www.ntis.gov/search/product.aspx?ABBR=N20120017925The recent experiments conducted by Argonne National Laboratory on high burnup fuel cladding material property show that the ductile to brittle transition temperature of high burnup fuel cladding is dependent on: (1) cladding material, (2) irradiatio ...http://www.ntis.gov/search/product.aspx?ABBR=DE20131068096The purpose of the Operational Testing and Evaluation (OT&E) phases of the project is to prepare for turnover of the Megaports system supplied by the U.S. Department of Energy/National Nuclear Security Administration (DOE/NNSA) located at the Export ...http://www.ntis.gov/search/product.aspx?ABBR=DE20131069213The Underground Test Area (UGTA) activity is responsible for assessing and evaluating the effects of the underground nuclear weapons tests on groundwater at the Nevada National Security Site (NNSS), formerly the Nevada Test Site (NTS), and implementi ...http://www.ntis.gov/search/product.aspx?ABBR=DE20131068057Latin America is once again playing an active role in economic and world affairs. This recent activism is taking place after the region experienced decades of stagnant growth, financial chaos, and political instability. To date, Latin American countr ...http://www.ntis.gov/search/product.aspx?ABBR=ADA571723The STAYSL PNNL software suite provides a set of tools for working with neutron activation rates measured in a nuclear fission reactor, an accelerator-based neutron source, or any neutron field to determine the neutron flux spectrum through a general ...http://www.ntis.gov/search/product.aspx?ABBR=DE20131067961
