本文件规定了对采用紫外线消毒技术（UVBWMS）的压载水管理系统（BWMS）的紫外线（UV）反应堆设计进行计算建模的方法。计算模型用于计算紫外线还原当量剂量（RED），并将缩放反应器的计算RED与其基础反应器进行比较。红色是使用具有给定剂量反应的生物体测定的。

This document specifies the methodology to conduct computational modelling of ultraviolet (UV) reactor designs for ballast water management systems (BWMS) that incorporate ultraviolet disinfection technology (UVBWMS). The computational modelling is used to calculate the UV reduction equivalent dose (RED) and to compare calculated REDs of the scaled reactor to its base reactor. REDs are determined using organisms with a given dose response.
