RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION RELATED TO LICENSE AMENDMENT REQUEST FOR CONDENSATE STORAGE TANK TECHNICAL SPECIFICATIONS Attachment Page 1 of 1 RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION A phone conversation was held on July 10, 2008 between Energy Northwest and the NRC Instrumentation and Controls Branch regarding Columbia's license amendment request associated with Condensate Storage Tank Technical Specifications. The following is a summary of the requests made during the phone call and the response to those requests.
Item 1 Please state how Columbia's staff responds to as-found trip values of level switch RCIC-LS-15A and 15B that are discovered to be less than the lower administrative limit but greater than the Technical Specification allowable value.
Response
When a RCIC-LS-1 5A/B level switch trip value is discovered to be less than the lower administrative limit but greater than the Technical Specification allowable value, the surveillance procedure for performing channel calibrations and functional tests directs Instrumentation and Control (I&C) maintenance staff to recalibrate the RCIC-LS-1 5A/B switch and functionally verify that the switch actuates within the, required calibration tolerance range (defined by the upper and lower as left limits). In addition, the procedure for I&C Work Practices requires condition reports to be generated whenever the as-found trip value is discovered to be outside the administrative limits. The terms "allowable value", "lower administrative limit", and "upper / lower as left limits" are used here as defined in Reference 2.
Item 2 Please clarify the response to item 2 provided in Energy Northwest's November 19, 2007 letter to the NRC as to whether or not the setpoint is a limiting safety system setting for a variable on which a safety limit (SL) has been placed....."
Columbia's response stated: "Neither proposed change involves a change to a limiting safety system setting variable."
Response
Columbia's response should have stated more clearly that "neither proposed change involves a change to a limiting safety system setting for a variable on which a safety limit has been placed."
