Jabbour .at l i Division of Operating Reactors M Mail Stop 542 1 Washington, D.C. 20555 ft Daar K: As you requested during our site visit to Milstone in support g ty of the Dresden #2 seismic evaluation effort, I rocoesmond that EGG ^ C perform the analysis of three piping systems, recirculation, LPCI cuction and seismic example problem 61 identified as being typical -Qi f-of the three methods used to seismically qualified Dresden 2 piping .%@V cystems. Specifically, I recommend the following analyses be performed: y A. Recirculation System }' 1. Analyze system using best estimate'of. support stiffness and analysis methods with seismic input from the J. Blume response spectral curves shown in Figure 1 assumed acting 2 first in the nominal N-S and then in the E-N horizontal directions plus 2/3 this spectrum in the vertical direction. Moment resultants are to be combined on both the SRSS and 2)- ABS bases. Resultant seismic stresses to be compared to J. Blume resultant seismic stresses at at least 3 common points. Seismic reaction forces in supports should also be determined and compared to J. Blume results if available. tA Stress intensification factors of NC 3600 should be used. 5 This effort has essentially been 'Iready completed in the Q'.)k suasnary report by~ M. 'E. Nitzel exer t~that the response spectra used as shwn in Fig. I h.4 been smoothed and broad-v oned somewhat from the' original Blume curves shown in Fig. 2 and the response spectra has been normalized to a 0.2 d 9 ZPGA rather than 0.lg OBE 2PGA which was used by Blume. ,y The purpose of this analysis is to evaluate the adequacy and accuracy of the original Blume analysis which is'also applicable to steam and feedwater systems. 2. Analyze recirculation system as in (1) above except assume supports are rigid and compara results with J. Blume. 3. Analyze recirculation system using best estimate of support stiffness and using current multi-degree of freedom model and modal analysis methods for the revised EDAC SSE
