核燃料技术.核材料衡算用容器校准和体积测定.第1部分:程序综述

[中文适用范围]： ISO 18213 的这一部分描述了配备用于确定液体含量的压力测量系统的核处理储罐的储罐校准和体积确定程序。 具体而言，为规划校准练习提供了总体指导，该校准练习是为了获取测量方程所需的数据来估计储罐容积。 还介绍了该过程中的关键步骤，以便随后使用估计的体积测量方程来确定罐液体体积。 所提出的程序特别适用于配备有起泡器探头系统的用于测量液体含量的储罐。 此外，这些程序仅对处于热平衡和静态平衡的澄清（即没有悬浮固体）、均质液体产生可靠的结果。 [外文原描述]： ISO 18213-1:2007 describes procedures for tank calibration and volume determination for nuclear process tanks equipped with pressure-measurement systems for determining liquid content. Specifically, overall guidance is provided for planning a calibration exercise undertaken to obtain the data required for the equation to estimate a tank's volume and the key steps in the procedure are presented for subsequently using the estimated volume-measurement equation to determine tank liquid volumes. The procedures presented apply specifically to tanks equipped with bubbler probe systems for measuring liquid content. Moreover, these procedures produce reliable results only for clear (i.e., without suspended solids), homogeneous liquids that are at both thermal and static equilibrium.
