Advance copies of all the requested data were furnished to the staff and discussed at that time. It is our understanding that the data submitted herewith will serve as a basis for the resolution of acceptable ampliefied response spectra based on soil structure interaction to serve as a basis for reevaluation o' piping sys tems under earthquake induced Ic.ading.

ATTACHMENT RESPONSE TO NRC LETTER OF MAY 18, 1979 CONCERNING USE OF SOIL STRUCTURE INTEllACTION MAY 24, 1979 BEAVER VALLEY POWER STATION UNIT 1 DUQUESNE LIGHT COMPANY 2261 ;29
May 24, 1979 Docket No. 50-334 USE OF SOIL PROPERTIES IN DEVELOPMENT OF SOIL-STRUCTURE INTERACTION AMPLIFIED RESPONSE SPECTRA The following procedures were followed to cbtain soil properties for the soil-structure interaction analyses at the Beaver Valley 1 site for development of SSI based ARS: First, a small strain soil profile was developed from the best available soil data, including cross hole seismic shear wave velocity measurements, as well as data from borings and samples. Second, the effect of an earthquake in the free field was evaluated using the SHAKE computer program. The control motion was specified at the surface of the free field; two real records were used - El Centro and Taft - normalized to the acceleration level of the specified design earthquake (OBE or DBE). The program iterated to obtain values of shear modulus and damping compatible with the levels of strain developed during the earthquake. The average of the results from the two records was used in further analyses and is here called the strain compatible, free field profile. Third, the moduli and material darping for the strain compatible, free field profile were used for tne REFUND / FRIDAY analyses. Fourth, the motion at the base of the profile obtained in the SHAKE analysis of the free field was input to several profiles representing the soil column under the Category I buildings. The top layers of these profiles hr.d masses and fundamental periods equivalent to those of the corresponding buildings. The small strain values of soil shear moduli were adjusted to account for the additional static stresses imposed by the buildings. The computer program SHAKE was run to obtain strain compatible moduli and damping values for each building profile. The average of results for the two time histories established each profile. Fifth, the strain compatible properties under each building were used in the finite element dynamic analyses as soil properties directly under the corresponding buildings. The strain compatible, free field soil properties were us.3d for the elements representing the free field. Strain compatible soil properties were interpolated between these values for two columns of elements adjacent to the building. Sixth, no further iteration on soil properties was performed in either the REFUND / FRIDAY or the finite element analysis. 2261 330
SHAKE ANALYSES BEA72)]_ VALLEY POWER STATION - UNIT NO.1 The strain dependent soil properties, shear modulus and damping. were analyzed with SHAKE for the free-field and reactor containment. These analyses were conducted using small strain shear moduli (Gmax) and site dependent soil unit weights. Two earthqaake real time histories, Taft and El Centro, were normalized to ground surface accelerations of 0.125g (D9E) and 0.06g (OBE), deconvoluted to bedrock and amplified to the reactor foundation. The results of the free-field and reactor analyses are shown in Table 2.4-1 and 2.4-2 At the request of the NRC two additional analyses are conducted on small strain (Gmax) values of plus and minus 50 percent. Both the free-field and reactor containment were analyzed using techniques described above. The results of these analyses are preser.ted in Tables 2,4-12 thru 2.4-15. 2261 331

RESPONSE SPECTRA AT BASE OF CONTAINME]h BEAVER VALLEY POWER STATION - UNIT NO 1 The ground response spectra at the base of the reactor contain-ment structure was calculated and plotted using SHAKE. The artificial earthquake developed for the Beaver Valley sito was normalized to the Deisgn Basis Earthquake (DBE) maxt=um acceleration of 0.125g and input at the ground surface of the free-field profile. The earthquake motion was deconvoluted to the base of the profile and the computed motion at elevation 681 ft, the contain=ent founding grade, was used to compute the real velocity and acceleration response spectra and the tripartite plot of real displacement, pseudovelocity, and pseudo-acceleration vs. frequency. These spectra are plotted for damping ratios of .5.1.0, and 3.0 percent. Response spectra were calculated for three soil profiles, represent-ed by the shear modulus (Gmax) calculated from seiLmic cross-hole surveys, Gmax plus 50 percent, and Gmax minus 50 percent. The spectra for each soil profile are plotted on Figures 1, 2, and 3, respectively. Also plotted on these figures is the ground response spectra for .5 percent damping presented in the Beaver Valley Unit No.1 FSAR. 2261 140
