- Scope
- This standard specifies the basic requirements for the design and manufacture of insulation layers for reactor pressure vessels and reactor coolant system piping and equipment (including steam generators, pressure regulators and main pumps, the same below) in pressurized water reactor nuclear power plants. This standard is applicable to the design and manufacture of insulation layers of reactor pressure vessels and reactor coolant system piping and equipment of pressurized water reactor nuclear power plants. The design and manufacture of insulation layers of other system piping or equipment connected to the reactor coolant system can also be used with reference.
