適用范圍：This standard applies to the protection system of a nuclear reactor and, more especially, to all interconnections between a reactor protection system (as defined and explained in IEC Publication 231 A, First supplement to Publication 231, General Principles of Nuclear Reactor Instrumentation) and all other systems and equipment not part of the protection system, except:a) the physical connection between sensors of the protection system and the physical variables that they monitor, such as for example, thermowells, moderating medium for neutron sensors, etc;b) the electrical connection between the protection system and the reactor control rods or other safety mechanisms;c) the electrical and pneumatic connections to the power distribution system (mains) and pneu-matic supplies that supply power to the protection system.Although many clauses rel?te to all reactor protection systems, this standard applies mainly to protection systems in nuclear power reactors.
