Methods for the accountability of reprocessing plant dissolver and waste solutions

This publication provides guidance on methods and procedures for the accountability of reprocessing plant dissolver and waste solutions. Adherence to the recommendations detailed therein will enable the user to control these materials to a degree consistent with recent measurement capability. The scope of this publication is limited to chemical and/or destructive analytical techniques and omits methods of non-destructive analysis. This document details methods for the accountability of the total plutonium, the total fissile plutonium (Pu and Pu), the total uranium and the total fissile uranium (U) in solutions resulting from the reprocessing of spent light water reactor fuel. It is concerned only with the input dissolver solution (accountability tank), the residual uranium and plutonium in the leached hulls, and the waste streams in the separation process. Methods for the accountability of products of the reprocessing plant have been given in previously issued manuals.
