摘要
Abstract
Achieving exactly quantitative holdup in uranium produced tank is a key point for nuclear material account and control .Due to the tank’ s particularity design and gamma ray remarkable self-absorption , conventional calibration methods can ’ t be adopted for self-absorption data analysis .The self-absorption correction method in the special case was researched , and also a two-dimensional model for self-absorption correction was established .It is available for these cases such as thickness of the material , matrix ingredients and geometric are incomprehensive . The validation of simulation sample shows that the two-dimensional model meets the requirement of holdup measure-ment in uranium produced tank .关键词
