The U.S. Nuclear Regulatory Commission (NRC) is issuing Revision 2 to Regulatory Guide (RG) 1.151, ``Instrument Sensing Lines.'' RG 1.151 describes an approach that is acceptable to the staff of the NRC to meet regulatory requirements for instrument sensing lines in nuclear power plants. The RG would endorse, with certain exceptions, standards that were updated and corrected subsequent to the last time the NRC endorsed them in RG 1.151. More information on updates can be found in the Supplementary Information section below.
