2.0 Seismic Design Basis
The site seismic horizontal ground response spectra used in the design of Indian Point 3 are shown in Figures 3 and 4 for the OBE and DBE respectively. The vertical ground response spectra components are defined as two-thirds of the horizontal ground response spectra. The response spectra were developed from the average acceleration velocity displacement curves presented in TID-7024, "Nuclear Reactors and Earthquake," for large-magnitude earthquakes at moderate distances from the epicenter. As such, the curves are made up of the combined normalized response spectrum determined from components of four strong-motion ground accelerations: El Centro, California, December 30 1934; El Centro, California, May 18, 1940; Olympia, Washington, April 13, 1949; and Taft, California, July 21, 1952.
Indian Point Unit No. 3 was designed for both the Design Basis Earthquake (DBE) and the Operating Basis Earthquake (OBE). The peak ground acceleration levels associated with each of these earthquakes is given below:
Design Basis Earthquake
0.1 5g horizontal ground acceleration component 0.10g vertical ground acceleration component
Operating Basis Earthquake
0.10Og horizontal ground acceleration component 0.05g vertical ground acceleration component
These seismic acceleration values were established based on the seismology associated with the plant site. The nearest event larger than the Modified Mercalli intensity VII occurred near Cape Ann, Massachusetts in 1755. This event was classified as intensity ViIl on the Modified Mercalli Scale. However, the location of this event was more than 200 miles from the site. There are faults that pass through the foundations of Unit 3 structures. These faults are not capable per Appendix A of 10OCFR Part 100 definitions. More detailed information concerning seismology can be found in the plant FSAR, Chapter 2, Site and Environment, Section 2.8, Seismology.

3.0 Plant Seismic Analysis
Time history analyses were used to generate the floor response spectra for Indian Point Unit No. 3. A time history compatible with the Housner type site ground design response spectra (Figures 3 and 4) was used. Shown in Figures 5 and 6 are comparisons of the site design ground response spectra and the spectra associated with the time history for 2 and 5 percent damping normalized to 0.1g. The time histories were normalized to the OBE and DBE horizontal ground acceleration component levels for the respective analyses.
The DBE vertical floor response spectra are defined as equal to two-thirds of the horizontal DBE floor response spectra.
The floor response spectra were generally broadened by +/- 10% or larger as discussed in the plant FSAR, Section 16.1.3, under "Ground Response Spectra."
The damping values used in the design of seismic Class I components and structures are given in Table 1 as defined in the plant FSAR Table 16.1-1. It is noted that for the USI A-46 program, 5% damping will be used for the seismic analysis of SSER 1 safety equipment.
The plant site soil conditions are classified as rock, hard limestone formations. The building structures are founded on the rock. Therefore, soil structure interaction effects were not considered. The base of each building seismic model was fixed. The seismic criteria used was based on the seismic classification of the equipment and structures. The seismic classification was based on the recommendation given in:
o TID-7024, "Nuclear Reactors and Earthquakes," August, 1963, and
o G.W. Housner, "Design of Nuclear Power Reactors Against Earthquakes," Proceedings of the Second World Conference on Earthquake Engineering, Vol I, Japan, 1960, pg. 133. 134, and 137.
Equipment and structures were classified as seismic Class I, II, or Ill. A discussion of these classifications is given in the plant FSAR in Section 16.1.1, "Definition of Seismic Design Classifications." The seismic design criteria used for Indian Point Unit No. 3 for each of these classifications is presented in the plant FSAR, Chapter 16.

4.0 Floor Response Spectra Characteristics
In the design basis analyses performed in the early seventies, floor response spectra were developed for the following Seismic Class I structures at the Indian Point Unit No. 3 site:
o Containment Structure o Inner Containment Structure o Primary Auxiliary Building o Control and Diesel Generator Building o Fan House Building o Intake Structure o Spent Fuel Pit o Shield Wall
Each building/structure was modelled separately for the North-South and East-West response directions. Only one model was used when the building is symmetrical. The structural drawings were used in the development of the dynamic models. Multi-degreeof-freedom lumped mass elastic dynamic models were developed for each building/structure. Floor response spectra were developed from the time history motion associated with the floor as determined by dynamic analysis. The time history ground input was defined compatible with the defined ground response spectra for the site (see Section 2.0 above). The structures of interest are of reinforced concrete construction, therefore, the structural damping used for the building structures in the DBE seismic analyses was 5 percent. The rigid region associated with each of the floor response spectra was defined as beginning at 25 Hz.
Provided in the sections that follow are the following for each of the identified structures:
o Building Dynamic Characteristics: natural frequencies of dominant building modes contributing to the in-structure response spectra; lateral mode shape components; and participation factors
o In-structure DBE response spectra (broadened and unbroadened) at important floor locations in each building
o Peak floor acceleration values at the important floor locations where response spectra are provided
0 Amplification factors associated with the floor response spectra provided, defined as the ratio of the peak floor spectral acceleration value (at 2% and 5% equipment damping) to ground DBE ZPA value (0.15g) as well as floor ZPA values.
The amplifications of the spectra peaks are reasonable. The amplifications are similar to those expected from random motion and sine beats between 5 to 10 cycles per beat (Reference 1) when the building motion is amplified. For building motion associated with structures responding near the "rigid" region, or points low in the building, the response is similar to the ground response spectrum. This is seen in the summary tables provided for each of the buildings/structures given in the sections that follow.
4.1 Containment Structure
The Reactor Containment is a steel lined reinforced concrete right cylinder with a hemispherical dome and a flat base. The steel liner is a welded plate with a minimum thickness of one-quarter inch. It is attached by stud anchors to the inside face of the concrete. The containment structure cylindrical wall measures 148 feet from the basemat liner to the springline of the dome, and has an inside diameter of 135 feet. The concrete walls of the cylinder and the dome are 4'6" and 3'6" thick respectively. The inside radius of the dome is equal to the inside radius of the cylinder so that the discontinuity at the springline due to the change in thickness is on the outer surface. The flat concrete base mat is 9' thick with the bottom liner plate located on top of this mat. The bottom liner plate is covered with 3' structural slab of concrete which serves to carry internal equipment loads and forms the floor of the containment. The top of the base mat is at grade (El 43'). A General Elevation drawing of the Containment Building is shown in Figure 7. It was obtained from the plant FSAR, Figure No. 5.1.7. One lump mass dynamic model was used for both the North-South and East-West directions since the structure is symmetrical. The model is shown in Figure 8. Floor response spectra associated with the DBE are given in Figures 9 and 10 (broadened and unbroadened) for mass point 3. Mass point 3 is located at Elevation 213'5". The dominant mode of the Containment Structure is at approximately 4 Hz. Given in Table 2 are the frequencies and lateral mode shape components and participation factors associated with the significant modes. Given below is a summary of important key parameters associated with the horizontal spectra using mass point 3 and the peak at 4.2 Hz.

4.2 Inner Containment Structure
The Inner Containment structure includes the basemat, shielding, reactor cavity and canal for fuel transfer, and miscellaneous concrete and steel for floors and stairs. A three foot thick concrete ring wall, serving as a missile and partial radiation shield, surrounds the Reactor Coolant System components and supports the polar-type reactor containment crane. A 2' thick reinforced concrete floor covers the Reactor Coolant System, with removable gratings in the floor provided for crane access to the equipment underneath the floor. The operating deck is at Elevation 94 feet. The Inner Containment Structure is shown in Figure 7 given in Section 4.1.
Two separate lump mass dynamic models were used for both the North-South and EastWest directions. These models are shown in Figure 11.
Floor response spectra associated with the DBE are given in Figures 12 to 15 (broadened and unbroadened) for mass point 5 which is on the operating deck. The dominant mode is at a frequency of approximately 17 Hz and is associated with the North-South direction. The other modes, considering both the North-South and EastWest directions, are above 30 Hz. Given in Table 3 and 4 are the frequencies and lateral mode shape components and participation factors associated with the significant modes.
Given below is a summary of important key parameters associated with the mass point 5 horizontal spectra using the spectra peaks at 17.1 Hz (North-South direction). The East-West direction was not considered since the fundamental frequency is above 30 Hz.

4.3 Primary Auxiliary Building
The Primary Auxiliary Building is a reinforced concrete structure. The finished ground level around the building is 54'. In modelling the building it was assumed that the section below 41' is stiff ("rigid"). Cross sectional view of the building are given in Figure 16, obtained from the plant FSAR Figure No. 1.2-6.
The building was modelled separately in the North-South and East-West directions. However, the same basic model represents both directions, as shown in Figure 17, with different member stiffnesses.
Floor response spectra associated with the DBE are given in Figures 18 to 21 (broadened and unbroadened) for mass point 4 which is at Elevation 90'. The dominant mode is at a frequency of approximately 14.5 Hz for both the North-South and EastWest directions. The other modes are above 35 Hz. Given in Table 5 and 6 are the frequencies and lateral mode shape components and participation factors associated with the first two modes.
Given below is a summary of important key parameters associated with the mass point 4 horizontal spectra using the spectra peaks in the frequency region of 14.5 Hz.

4.8 Shield Wall
The Shield Wall is of concrete construction located outside of the Containment Structure. Its foundation is at Elevation 7'0". The location of the Shield Wall is shown in Figure 47 as defined by the plant FSAR Figure No. 5.1-5. The dynamic model is shown on Figure 48. The North-South model responds in the plane of the paper; whereas, the East-West model is a grid model responding normal to the plane of paper.
Floor response spectra associated with the DBE are given in Figures 49 to 52 (broadened and unbroadened) for mass point 2 which is at Elevation 78'0". The dominant mode frequencies are approximately 3 Hz for the East-West direction, and 15 Hz for the North-South direction. Given in Tables 15 and 16 are the frequencies, lateral mode shapes, and participation factors associated with the significant modes. Given below is a summary of important key parameters for the mass point 2 spectra associated with the frequency region of dominant response.
