RESPONSES TO NRC REQUEST FOR INFORMATION SSI ANALYSIS OF SONGS-i TURBINE BUILDING NRC REQUEST NO.1:
Provide summary of differences, if any, between Test Problem solutions provided previously and current methods. In particular, this is applicable to current Turbine Building response spectra correction factors and original FLORA methodology.
SCE RESPONSE:
In the solution of NRC test problem III (Reference 1), the "improved" wide-band option in program FLORA was used.
This option accurately computes response spectral values for cases when the frequencies of the structure are close to the frequencies at which a spectral value is calculated (i.e., for "tuned" systems).
A computer program (program FACTOR) was written for the computation of the correction factors, applied to the Turbine Building spectra.
The program FACTOR uses the basic methodology in program FLORA with the simplifying assumption of detuning between the structural frequencies and the requested spectral frequencies. This assumption is acceptable because we are not interested in the absolute value of the spectral response (since we have all the spectral values from the time histories) but are solely interested in the ratio of spectral values calculated by consistent formulations. It will be shown in "SCE response to NRC Request No. 2," of this report that the calculation of this ratio is independent of the method used to compute spectral ordinates.

NRC REQUEST NO. 2:
Use FLORA narrow-band methodology to calculate correction factors at two spectral points at two independent Turbine Building nodes and compare with analysis values.
SCE RESPONSE:
I The objective of this request is to validate the method for computation of the correction factors used for the Turbine Building response spectra. The correction factors werecalculated using the program FACTOR. The methodology used for the computation of these correction factors will be validated by computing the correction factors using the program FLORA. The NRC has approved the use of FLORA for SONGS-1 LTS evaluations. Furthermore, for purposes of the requested validation, the same test program used for the validation of FLORA will be used (Reference 1).
Correction factors will be calculated using both the wide-band and the narrow-band FLORA options to generate spectra.
I The model used for the analysis is shown in Figure 2.1.
This is a fixed-base model provided by the NRC for FLORA verification purposes (NRC-test problem III, Reference 1).
The modal properties (frequencies, mode shapes) generated for the test problem were used for the computation of the correction factors.
The design response spectrum (Modified Housner) and the response spectrum corresponding to the time history (North-South direction) for 4 percent damping were used as input. Both the design and the time history spectra are shown in Figure 2.2. The structural composite modal damping ratios were also assumed to be 4 percent for all modes.
The analyses were performed using the structure's modal properties and the two input spectra. The procedure consists of evaluating the spectral ordinates for each input spectrum and I
taking the ratio of the results. The ratio of the spectral value obtained using the design spectrum to the spectral value obtained using the time history's spectrum gives the "correction factor."
Correction factors were evaluated for the following cases:
- 1) Using the methodology in program FACTOR
- 2) Using the FLORA wide-band approach
- 3) Using the FLORA narrow-band approac-h Spectral values were computed at two nodes (node 4 and 11) in the model and at a total of 26 frequencies, including the fundamental structural frequency (5.26 Hz).
Consistent with the application used used for the Turbine Building, the mass of the secondary system is zero (EM=O), i.e.,
primary-secondary system interaction is not considered.
I I
RESULTS:
S able 2.1 shows a comparison of the correction factors. For each frequency nd each node, the percentage difference between the correction factor calculated using FACTOR and FLORA are calculated as follows:
% differenceForrection factor using FACTOR 1
FACTOR VS. FLORA (Wide-Band) [
Correction factor using FLORA (Wide-Band) x 100
% difference Correction factor using FACTOR 00 FACTOR VS. FLORA (Narrow-Band) = Correction factor using FLORA (Narrow-Band) -1 x 100 Table 2.1 shows that the method used to calculate the correction factors implemented in the Turbine Building spectra are similar to those calculated with FLORA using either the wide-or the narrow-band options. In Table 2.1, a positive percentage difference indicates that the values calculated by FACTOR are conservative, i.e., less reduction is applied to the time history's spectra. As shown in the Table 2.1, the largest differences between FACTOR and FLORA are positive, thus conservative.
CONCLUSION:
The methodology used for the development of correction factors applied for the Turbine Building response spectra is correct and conservative.
