HLNC calibration and application to waste measurement

Lu, Ming Shih; Teichmann, T.; De Ridder, P.M. - 2008

This paper addresses problems of calibration and estimation of a parameter, p{sub o}, in high level neutron coincidence counting (HLNC) measurement. The presentation begins with a deductive approach, based on the generally accepted physical equations which are satisfied by the total and...

A further study of the impact of bias on accountability

Harvey, T.R.; McGuire, S.A. - 2009

When measurements are obtained for the purpose of material accountability, any deviation of averages from true value is one of great concern. The key term here is true value. Any deviation of averages from their true value will result in inventory discrepancies. It will not matter that the bias...

Estimation of expected value for lognormal and gamma distributions. [Environmental pollutants]

White, G.C. - 2009

Concentrations of environmental pollutants tend to follow positively skewed frequency distributions. Two such density functions are the gamma and lognormal. Minimum variance unbiased estimators of the expected value for both densities are available. The small sample statistical properties of...

Hanford transuranic analytical capability

McVey, C.B. - 2009

With the current DOE focus on ER/WM programs, an increase in the quantity of waste samples that requires detailed analysis is forecasted. One of the prime areas of growth is the demand for DOE environmental protocol analyses of TRU waste samples. Currently there is no laboratory capacity to...
