Initial Test Program of Condensate and Feedwater Systems for Light-Water Reactors

The U.S. Nuclear Regulatory Commission (NRC or the Commission) is issuing for public comment draft regulatory guide (DG), DG-1265, "Initial Test Program of Condensate and Feedwater Systems for Light- Water Reactors." DG-1265 is proposed revision 2 of Regulatory Guide 1.68.1, "Preoperational and Initial Startup Testing of Feedwater and Condensate Systems for Boiling Water Reactor Power Plants," dated January 1977. This regulatory guide is being revised to: (1) expand the scope of the guide to encompass preoperational, initial plant startup, and power ascension tests for the condensate and feedwater systems in all types of light water reactor facilities licensed under Title 10 of the Code of Federal Regulations (10 CFR) Parts 50 and 52; and (2) to incorporate lessons learned by the NRC staff since the last revision.
