The response to RAI EMCB.203/164 (Unit 2 plots) is scheduled to be submitted by January 23, 2009. The schedule for providing the response to the remaining draft Round 23 RAI (EMCB.204/168) is being developed and will be discussed with the NRC staff.

RESPONSE TO ROUND 23 REQUEST FOR ADDITIONAL INFORMATION (RAI)
REGARDING STEAM DRYER SIGNAL PROCESSING (NON-PROPRIETARY VERSION)
Attached is the non-proprietary version of the Response to Round 23 RAI Regarding Steam Dryer Signal Processing.
NON-PROPRIETARY INFORMATION NRC RAI EMCB.202/163 (Units 1 and 2)
In the response to EMCB 200./157., TVA states that the coherence between the upper and lower strain gage arrays is modified by removing EIC signals from the individual strain gage autospectra (step 1). Then, notch filters are applied to remove tones from the signals which are unrelated to dryer loads (step 2). In step 3, the coherence between the modified upper and lower strain gage array signals is computed. The coherence between two spectra is:
2 y 2=IG 12 1/(Gjj*G 22 ),
where G12 is the cross-spectrum between the two signals, and G1 i and G22 are the autospectra of the individual signals. Explain how G12 is modified after using EIC signals and notch filters prior to being used in the coherence calculation. This explanation should include how both the magnitude and phase of G12 are modified.
TVA Response to EMCB.202/163 (Units 1 and 2)
The cross spectra G 12 is never directly calculated but is one of three factors in the computation 2
of the coherence. The coherence is y 62 212
=
G,1 *G22 where G11 is the auto spectra at location 1 G 22 is the auto spectra at location 2 G 12 is the cross spectrum between locations 1 and 2 and the coherence is only used to condition the current licensed thermal power (CLTP) and low flow (LF) main steam line (MSL) strain gage pressure signals immediately prior to the subtraction (scaling) of the CLTP data by the LF data. To see first that there is little change to the cross spectra at CLTP conditions as result of signal conditioning, we have plotted the coherence between the upper and lower strain gage data from each steam line at CLTP conditions from the raw data and after notch filtering in Figures EMCB.202/163-5a and 5b. In general, the coherence is very similar except at discrete frequencies which have been notch filtered as expected.
To see how the magnitude and phase of G12 are modified, see Figures EMCB.202/163-1a through ld where the CLTP and corresponding electrical interference check (EIC) cross spectra magnitude and CLTP cross spectra phase between upper and lower raw data from the steam lines are shown. The phase of the EIC cross spectra is not shown as it is randomly distributed in frequency.
Figures EMCB.202/163-2a through 2b provide the above mentioned spectra on low power, designated LF. It is clear that the cross spectrum magnitude indicates no correlation except at 60, 120, 180 and 240 Hertz (Hz).
In Figures EMCB.202/163-3a through 3d the cross spectra magnitude and phase after EIC subtraction (scaling) for CLTP and LF data are shown.
In Figures EMCB.202/163-4a through 4d, the cross spectra magnitude and phase are shown after notch filtering for the CLTP and LF data. One could compare the cross spectra before and after notch filtering by comparing Figures EMCB.202/163-3 and 4. At this point, the coherence E2-1
NON-PROPRIETARY INFORMATION would seem more relevant as it is used to condition the CLTP and LF data sets. Examine Figures EMCB.202/163-5 and 6 for coherence discussed above to determine that there has been little change in the cross spectrum when normalized by the auto spectra from CLTP and LF, respectively, except at discrete frequencies as expected.
