Monticello - Proposed EPU Amendment, additional draft question re. steam dryer (TAC MD9990)
Ken:
On 3/20/09 I sent you a draft RAI consisting of 19 questions regarding the steam dryer. I just received an additional question from our Mechanical and civil Engineering Branch. Please let me know if you want to discuss this question with the NRC staff in a conference call:
EMCB-SD-RAI-20 In the steam dryer evaluation for MNGP, the main steam line (MSL) strain gage measurements from 2007 at CLTP power level were reduced by subtracting: 2008 data acquired at low power (LP) conditions in the plant.
According to Attachment II of Enclosure 11 to its letter of November 5, 2008, the licensee utilizes the acoustic circuit model (ACM), Rev. 4 (described in Reference 3, CDI Report 07-09P, Rev. 0) that was benchmarked using Quad Cities 2 (QC2) main steam line and steam dryer measurements. The licensee used the QC2 benchmark data to compute the frequency dependent bias errors and uncertainties for applying to MNGP. The MSL strain gage measurements used for the QC2 benchmark did not subtract LP data, whereas MNGP data used for dryer qualification subtracted the LP data.
Address the apparent inconsistency with the conclusion that the bias errors and uncertainties in CDI Report 07-09P are conservative given that the benchmarked code (QC2) did not subtract the LP data. Demonstrate by analyses that the bias and uncertainties assumed in CDI Report 07-09P are applicable to MNGP where LP noise is subtracted.
