MODELING ATMOSPHERIC RELEASES OF TRITIUM FROM NUCLEAR INSTALLATIONS
Tritium source term analysis and the subsequent dispersion and consequence analyses supporting the safety documentation of Department of Energy nuclear facilities are especially sensitive to the applied software analysis methodology, input data and user assumptions. Three sequential areas in tritium accident analysis are examined in this study to illustrate where the analyst should exercise caution. Included are: (1) the development of a tritium oxide source term; (2) use of a full tritium dispersion model based on site-specific information to determine an appropriate deposition scaling factor for use in more simplified, broader modeling, and (3) derivation of a special tritium compound (STC) dose conversion factor for consequence analysis, consistent with the nature of the originating source material. It is recommended that unless supporting, defensible evidence is available to the contrary, the tritium release analyses should assume tritium oxide as the species released (or chemically transformed under accident's environment). Important exceptions include STC situations and laboratory-scale releases of hydrogen gas. In the modeling of the environmental transport, a full phenomenology model suggests that a deposition velocity of 0.5 cm/s is an appropriate value for environmental features of the Savannah River Site. This value is bounding for certain situations but non-conservative compared to …

Models for Gamma-Ray Bursts and Diverse Transients
The observational diversity of ''gamma-ray bursts'' (GRBs) has been increasing, and the natural inclination is a proliferation of models. We explore the possibility that at least part of this diversity is a consequence of a single basic model for the central engine operating in a massive star of variable mass, differential rotation rate, and mass loss rate. Whatever that central engine may be--and here the collapsar is used as a reference point--it must be capable of generating both a narrowly collimated, highly relativistic jet to make the GRB, and a wide angle, sub-relativistic outflow responsible for exploding the star and making the supernova bright. To some extent, the two components may vary independently, so it is possible to produce a variety of jet energies and supernova luminosities. We explore, in particular, the production of low energy bursts and find a lower limit, {approx} 10{sup 48} erg s{sup -1} to the power required for a jet to escape a massive star before that star either explodes or is accreted. Lower energy bursts and ''suffocated'' bursts may be particularly prevalent when the metallicity is high, i.e., in the modern universe at low redshift.

NASA Procurement: Use of Award Fees for Achieving Program Outcomes Should Be Improved
A letter report issued by the Government Accountability Office with an abstract that begins "Cost-plus-award-fee contracts accounted for almost half of the National Aeronautic and Space Administration's (NASA) obligated contract dollars for fiscal years 2002-2004. Since 1990, we have identified NASA's contract management as a high-risk area--in part because of a lack of emphasis on end results. Congress asked us to examine (1) the extent NASA's guidance on award fees addresses problems previously identified with the use of award-fee contracts and (2) whether NASA follows its guidance in using award fees to achieve desired outcomes. We reviewed the top 10 dollar value award-fee contracts active from fiscal years 2002 through 2004."

Oral History Interview with Charles Liapes, January 17, 2007
The National Museum of the Pacific War presents and oral interview with Charles Liapes. Liapes was born in Newburg, New York 27 November 1921. Five of his brothers were in the service during World War II. Three were wounded and all returned home. In November 1942, Liapes volunteered for the Army and went to Fort McClelland for basic training. Upon completion of basic he traveled to England aboard HMS Queen Elizabeth (R-08) to attend a British Commando school. Completing the commando training he returned to the United States and volunteered for the paratroopers. He was assigned to the 506th Parachute Infantry Regiment, 101st Airborne Division. In May 1944 he made five jumps on three successive days to quickly qualify as a paratrooper. On 6 June 1944 he participated in Operation Overlord by jumping over France. He describes the action during and after the jump, seeing comrades and German soldiers killed. He also describes destroying a German tank during the battle of Sainte-Mere-Eglise. He was wounded but recovered prior to participating in Operation Market Garden. Soon after landing he was seriously wounded and sent to a hospital in England. From there he went to the military hospital in Framingham, Massachusetts and …

Pretest Predictions for Ventilation Tests
The objective of this calculation is to predict the temperatures of the ventilating air, waste package surface, concrete pipe walls, and insulation that will be developed during the ventilation tests involving various test conditions. The results will be used as input to the following three areas: (1) Decisions regarding testing set-up and performance. (2) Assessing how best to scale the test phenomena measured. (3) Validating numerical approach for modeling continuous ventilation. The scope of the calculation is to identify the physical mechanisms and parameters related to thermal response in the ventilation tests, and develop and describe numerical methods that can be used to calculate the effects of continuous ventilation. Sensitivity studies to assess the impact of variation of linear power densities (linear heat loads) and ventilation air flow rates are included. The calculation is limited to thermal effect only.

Properties of Ellipticity Correlation with Atmospheric Structure From Gemini South
Cosmic shear holds great promise for a precision independent measurement of {Omega}{sub m}, the mass density of the universe relative to the critical density. The signal is expected to be weak, so a thorough understanding of systematic effects is crucial. An important systematic effect is the atmosphere: shear power introduced by the atmosphere is larger than the expected signal. Algorithms exist to extract the cosmic shear from the atmospheric component, though a measure of their success applied to a range of seeing conditions is lacking. To gain insight into atmospheric shear, Gemini South imaging in conjunction with ground condition and satellite wind data were obtained. We find that under good seeing conditions Point-Spread-Function (PSF) correlations persist well beyond the separation typical of high-latitude stars. Under these conditions, ellipticity residuals based on a simple PSF interpolation can be reduced to within a factor of a few of the shot-noise induced ellipticity floor. We also find that the ellipticity residuals are highly correlated with wind direction. Finally, we correct stellar shapes using a more sophisticated procedure and generate shear statistics from stars. Under all seeing conditions in our data set the residual correlations lie everywhere below the target signal level. For good …
