核电厂稳压器下封头电加热元件安装区开孔补强计算

Nuclear power plant voltage regulator under the head of electric heating elements Installation area opening reinforcement calculation

压水堆核电厂稳压器下封头通常需要开70-90个布置较为密集的电加热元件安装孔。本文采用RCC-M和Н-ППУ-01两种压水堆核能设备强度计算标准对某核电工程稳压器下封头电加热元件安装区进行补强计算。经计算,采用两种标准对下封头电加热元件安装区域开孔补强计算均满足相应标准要求。

The pressure head of PWR nuclear power plant usually needs to open 70-90 electric heating element mounting holes which are more densely arranged.In this paper,RCC-M andН-ППУ-01 two kinds of pressurized water reactor nuclear equipment strength calculation standard of a nuclear power project under the header heating element mounting area reinforcement calculation.After calculation,two kinds of standards are used to meet the corresponding standard requirements for the reinforcement calculation of openings in the installation area of the lower header electric heating element.
