Subject:
Open item 3.1.6.3-1 You asked me to look at a second draft response to the subject open item. I have two comments. Please note that the draft SER incorrectly characterizes the staff's concem with the SW system ARDI. I dont know how to handle that.
Component Cooling 2, stem. If the applicant credits coatings with protecting the external surfaces of carbon steel piping, then what program ensures the coating remains intact for the next 40 years? The applicant does not credit its system walkdowns program for this system. Is this consistent with your j
approach in other systems? For example, I thought AFW and HVAC systems credit walkdowns to ensure coatings are intact and in good condition. Why is there no need to do that here? What is unique about this system?
Saltwater System: The open.' tem related to the SW system on page 3-34 of the SER incorrectly relates the open item to the rubber-lined components. The staff is actually concemed with corrosion of the external surfaces of the entire carbon steel and/or low alloy components of the SW system within the scope of license renewal due to leakage, of saltwater. Why limit the extent of the walkdowns to just the bolting? Is that the only carbon and/or, low alloy steel component in the system that could be exposed to leaking saltwater?
It's my understanding that this email and the previous email and the licensees' faxes will be placed on the docket.
