ISO 23466-2020 压水堆核电站反应堆冷却剂系统、主要设备和管道的保温设计规范 Design criteria for the thermal insulation of reactor coolant system main equipments and piping of PWR nuclear power plants

This document specifies the basic requirements of thermal insulation design of reactor coolant system 
(RCS) equipment and piping.
Among thermal insulation of various RCS equipment and piping, the following two kinds of thermal 
insulations are described in detailed based on common design logic and requirements:
— thermal insulation of reactor pressure vessel (RPV);
— thermal insulation of RCS piping and other equipment.
This document is valid for two types of thermal insulation:
— metallic thermal insulation;
— non-metallic thermal insulation.
This document mainly applies to nuclear power plants with pressurized water reactor (PWR). For other 
reactor types, this document can be taken as reference.st edition 2020-10 Design criteria for the thermal insulation of reactor coolant system main equipments and piping of PWR nuclear power plants Critères de conception du calorifuge des composants primaires principaux et des tuyauteries du circuit primaire principal des centrales nucléaires REP Reference number ISO 23466:2020(E) ？ ISO 2020 ISO 23466:2020(E) COPYRIGHT PROTECTED DOCUMENT
