Preoperational Testing of Instrument and Control Air Systems
The U.S. Nuclear Regulatory Commission (NRC or the Commission) is issuing for public comment draft regulatory guide (DG), DG-1268, "Preoperational Testing of Instrument and Control Air Systems." This regulatory guide is being revised to address new issues that have been raised since RG 1.68.3 was first issued. These include vibration testing of instrument and control air systems (ICAS) to meet seismic requirement, ICAS air-dryer testing to meet dew point design requirements, ICAS accumulator check valves and solenoid valves operating and testing experience, an update to ISA S7.3 for acceptable industry standards for oil, water and particle matter in ICAS.
