Background===
4 Columbia Power Levels Original Licensed Thermal Power 3323 MWt Current Licensed Thermal Power 3486 MWt Proposed MUR Thermal Power 3544 MWt Columbia is a BWR-5, Mark II containment
LAR Overview LAR technical evaluation based on NRC approved Topical Reports:
NEDC-32938P-A, Generic Guidelines and Evaluations for General Electric Boiling Water Reactor Thermal Power Optimization, May 2003 ER-80P, Improving Thermal Power Accuracy and Plant Safety While Increasing Operating Power Level Using the LEFM
'System, March 1997 ER-157P-A, Supplement to Caldon Topical Report ER-80P:
Basis for Power Uprates with an LEFM Check or an LEFM CheckPlus System, May 2008 5
LAR Overview (continued)
Completeness of information Addresses the criteria contained in the NRC Safety Evaluations for LEFM Topical Reports that are required to be addressed as part of the MUR request Contains a cross-reference matrix showing the location of information required by Attachment 1 of RIS 2002-03, Guidance on the Content of MUR Uprate Applications Incorporates responses to applicable requests for additional information from other MUR submittals 6
Leading Edge Flow Meter (LEFM)
Cameron Check Plus' Two LEFM systems installed in R22 (2015)
One on each feedwater line Uncertainty values determined by Alden Labs Commissioned through the Cameron Process Columbia specific operating experience using LEFM 7
LEFM - Modes of Operation 8
LEFM Modes of Operation Power Level LEFM Uncertainty Both in Check Plus Normal operation at 3544 MWt 0.3%
One in Check Plus and one in Check OR Both in Check Return to Check Plus OR Reduce power to 3537 MWt 0.5%
One or more in Fail Return to Check OR Reduce power to 3486 MWt N/A
LAR Schedule Outage implementation is preferred LAR Technical Review Complete Pre-submittal Meeting 5/2/2016 Bonneville Power Administration Grid Stability Report 7/1/2016 Submit Amendment Request 7/15/2016 Implement during refueling outage (R23) - starts 5/13/2017 Request approval prior to R23 (May 2017) 9
Conclusions Columbia MUR amendment request is based on NRC approved guidance Not accompanied by other (unrelated) requests or changes All required information is included in LAR submittal Includes a proposed power level for LEFM Check Mode Outage implementation is preferred Request 10-month NRC review period 10
