What is ISO 23466 about?
ISO 23466 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 detail based on common design logic and requirements:
- Thermal insulation of reactor pressure vessel (RPV)
- Thermal insulation of RCS piping and other equipment
ISO 23466 is valid for two types of thermal insulation:
- Metallic thermal insulation
- Non-metallic thermal insulation
ISO 23466 mainly applies to nuclear power plants with pressurized water reactors (PWR). For other reactor types, ISO 23466 can be taken as a reference.
Who is ISO 23466 for?
ISO 23466 on thermal insulation of reactor coolant system is relevant to:
- Mechanical engineers
- Nuclear scientists
- Researchers and scientists
- Chemical Engineers
- Manufacturers of thermal insulators
Why should you use ISO 23466?
A PWR was originally designed to provide naval propulsion for nuclear submarines; it was used in the original design of the second commercial power plant at the Shipping port Atomic Power Station
ISO 23466 provides designs, procedures and basic requirements for thermal insulation.
ISO 23466 specifies that the outer shell of thermal insulation can be attached using rivets or self-tapping screws. The spacing between the rivets or screws should be specified in the design document.
ISO 23466 describes the design procedures for thermal insulation that are intended to fulfil all functionalities. It also identifies the minimum requirements for the safety class, the quality assurance category, and the seismic category for equipment, which will improve efficiency and safety.
