- Scope
- This standard specifies the design, installation and qualification requirements for safety-level circuit cable channel systems in nuclear power plants, and also specifies the methods for structural qualification of safety-level circuit cable channel systems. This standard applies to safety-level circuit cable channel systems outside electrical equipment and components of nuclear power plants, but does not take into account the effects of aging and irradiation. This standard does not apply to embedded parts connecting supports.
