Abstract
A measurement control program for a low enriched conversion-fabrication plant for LWR fuels is described. The program is used to control and estimate the volume, weight, U-element, and U-235 measurement errors. The principles and practical aspects of establishing a system of standards, replicate measurements, calibrations, and statistical applications are discussed. Engineering scale experimental approaches for estimating systematic sampling errors and the waste materials matrix bias for the passive gamma counting of U-235 in solid waste are also described.
