1. INTRODUCTION .

This report describes the scismic reanalysis of the Pilgrim Nuclear Power  :

Station (PNPS) Reactor Building as requested by Boston Edison in Reference 1 and subsequent correspondence.

The scope of work consisted of upgrading the Reactor Building dynamic model to current requirements; performin0 a soil-structure interaction (SSI) analysis using seismic inputs corresponding to (1) Re0ulatory Guide 1.60 ground response spectra anchored at 0.159 for SSE and 0.08 9 or f OBE, and (2) PNPS FSAR (Housner) ground response spectra anchored at 0.15g for SSE and 0.08g for OBE; and generating new in-structure response spectra suitable for use in future design activities.

The Reactor Building model was revised to be a 3-D model, rather than 2-D as originally developed, incorporating vertical and torsional properties. Mass and stiffness properties were recalculated using plant drawings and equip-ment locations. Internal structures were modeled separate!y: (1) the drywell vessel, (2) the torus suppression pool, (3) the biological shield, (4) the reactor pressure vessel, and (5) the reactor pedestal. The building model properties ,

were derived in a QA calculation (Reference 7) with all sources of information ,

documented. A schematic of the dynamic model with elevations for genera-tion of in-structure response specta is shown in Figure 1-1.

The SSI analysis was performed as a 3-D analysis in accordance with current practice. Input time histories to characterize the ground spectra were generated to meet current NRC requirements (Reference 2). Impedances and i scattering functions were computed using soil layer properties determined by others (Reference 13). The soil properties were coupled with the upgraded building model for analysis of the coupled soil-structure system. Soil para-meters were varied in accordance with Reference 2.

New in-structure response spectra were Denerated for both ground spectrum inputs (Regulatory Guide 1.60 and PNPS FSAR) and for SSE and OBE. The new spectra were generated at the points contained in BECo Specification C-i 114, the torus, and El. 27.17 on the drywell vessel. Foi the main building l

~1 floor elevations, the new spectra consist of an envelope of the center of mass location and the four extreme corners of the floors in order to capture torsional effects. The spectra for the torus is an envelope of four points around the circumference of the vessel. All spectra envelop the best estimate, upper bound, and lower bound soil cases, and are broadaned in accordance with current criteria. A flow chart of the analysis process is shown in Figure 1-2. The computer programs used in each step are shown ,in parenthesis in each box.

The new spectra for the Regulatory Guide 1.60 SSE ground spectrum input are contained in Attachment A to this report. All analysis was performed and documented in accordance with EQE QA procedures. Computer program inputs and outputs are saved on electronic media, t

2. TECHNICAL APPROACH i

2.1 Overview in this chapter, the technical process used by EQE to perform the soil-structure interaction (SSI) analysis of the PNPS Reactor Building is described.

The major tasks involved in the seismic analysis of the PNPS Reactor Building are described here in general terms.

In the last decade, significant advances have been made in the area of SSI  :

analysis. Better and more theoretically sound SSI analysis techniques have i been deveioped and implemented, and experience has been gained in their use. Theoretical developments and experimental programs have furthered the ,

understanding of the combined behavior of soil-structure systems with the spatial variation of ground motions. Better and more efficient techniques have been developed for the generation of site-specific seismic motions, and a significant amount of data has been collected. Questions regarding the location of the control motion for the analyses, acceptable radiation damping, soil material behavior, variability of the soil and structure properties have been addressed with analytical and experimental studies. All of these advances have culminated in regulatory revisions as evidenced by Revision 2 of the USNRC Standard Review Plan (SRP), Section 3.7, NUREG-0800 (Reference 2).

The overall approach is described here in the context of the substructure  ;

method to SSI. The substructure approach is particularly attractive for SSI analysis. It separates the SSI problem into a series of simpler problems, +

solves each independently, and superimposes the results. This approach allows one to examine meaningfulintermediate results and perform sensitivity studies in a cost-effective fashion. The elements of the substructure approach as applied to structures subjected to earthquake excitations are:

(1) specifying the free-field ground motion; (2) defining the soil profile; (3)

.- l

'I 42103-R 001 Revision 0 July 30,1993 Page 12 of 79 performing site response analysis; (4) calculating the foundation input motion; (5) calculating the foundation impedances; (6) determining the dynamic characteristics of the structure; and (7) performing the SSI analysis, i.e.,

combining the previous steps to calculate the response of the coupled soil-structure system. Figure 2-1 shows the several steps schematically. A brief discussion of each of these elements and their applicability to the PNPS Reactor Building is given below.

2.2 Free-field Ground Motion Specification of the free-field ground motion entails specifying the control point, the frequency characteristics of the control motion (typically, time histories or response spectra), and the spatial variation of the motion. For the PNPS Reactor Building, the free-field ground motiens are described by the PNPS FSAR (Housner) and Regulatory Guide 1.60 response spectra applied at finished grade in the free field (Reference 1). The SSI analysis will utilize artificial acceleration time histories generated to the criteria of NRC SRP Section 3.7.1 (Reference 2). Generating the time histories is a simple yet critical task. Any excess conservatism incorporated in the time histories in a frequency range including or close to the principal soil-structure system frequencies will be directly transmitted to the floor response spectra and impact the design and evaluation of plant components. Therefore, the reduction of unnecessary conservatism in the artificial time histories meeting the requirements of the SRP Section 3.7.1 deserves special attention. EQE proprietary computer code FIT has been developed to meet the SRP Section 3.7.1 requirements without introducing unnecessary conservatism by closely matching target response spectra. Figure 2-2 compares a representative-response spectrum corresponding to an artificial acceleration time history generated with the program FIT using the horizontal SSE design spectrum at 5% damping for a typical site as the target. A very close match is observed.

Figure 2-3 and 2-4 compare the response spectra of artificial acceleration

F' I: 42103-R-001 Revision 0 July 30,1993 Page 13 of 79 time histories generated with the program FIT using Housner and Regulatory Guide 1.60 as the target spectra. Time histories generated in this fashion -

closely fit target response spectra, meet the SRP Section 3.7.1 criteria, and are realistic time functions as shown in Figure 2-2. They eliminate unwanted conservatism in the SSI analysis and in the generation of floor response spectra, in addition to enveloping the design response spectra, the artificial time histories rnust comply with requirements of compatibility of energy dist ibutions with the target motions. To ensure that the artificial time histories do not have frequency rangm with deficient energy content, the power spectral density functions of the artificial time histories t re compared with the requirements of Reference 2.

1 2.3 Soil Profile l

l Defining the soil profile for SSI analysis first involves defining the low strain {

l soit properties as a function of depth. This is usually done from site data j 4

i compiled by the geotechnical engineer. The important pararneters for the SSI analysis are soil shear modulus, soil material damping, Poisson's ratio, mass density, and water table location--all as a function of depth in the soil. An additional aspect of defining the soil properties is the variation in soil shear I modulus and soil material damping with shear strain level, i.e., the reduction in shear modulus and the increase in damping as shear strain increases. The I low strain soil profile for this work was provided by Boston Edison (Reference 13).

2.4 Site Response Analysis

.i l

A site response analysis serves two purposes: (1) estimate shear strain i compatible equivalent linear soil properties, and (2) calculate motions at i foundation depth in the free field to compare with SRP requirements.  !

-42103-R-001 Revision 0 ,

July 30,1993 j Page 14 of 79 The generetion of shear-strain compatible soil properties is an important step in the SSI analysis. Strain compatible soil shear modulus and soil material  :

damping will affect the motion at the foundation of the structuie and thus the seismic response, it is common practice, lacking site-specific laboratory test ' '

data, to use the soil material properties versus shear-strain relationships developed by Seed and Idriss (Reference 3) in conjunction with the computer program SHAKE (Reference 4) to estimate equivalent linear soit properties compatible with the soil shear strains induced by the design basis response ,

spectrum. The program SHAKE is a commonly used and well-accepted -

program in the nuclear industry for the development of equivalent linear strain compatible soil properties and for the calculation of time histories of motion at any location in the soil column. SHAKE is based upon one-dimensional vertical propagation of shear waves through linear viscoelastic soils consisting of homogeneous horizontal layers extending to infinity in the horizoral direction and overlying a homogeneous half-space. Figure 2-5 l

shows an example of variations of soil shear wave velocity and soil material damping compatible with soil shear strains obtained with the program SHAKE.

Based on Reference 1, the location of the control motion for the PNPS site is  ;

defined in the free field at the ground surface. In anticipation of the need to j i

perform SSI analyses for three soil profiles ~a best estimate, a lower range profile, and a higher range profile-- three site response analyses will be performed for each earthquake level (OBE and SSE) and each design response '

spectrum (PNPS FSAR and Regulatory Guide 1.60). l 1

To comply with the requirement in the SRP Section 3.7.2 (Reference 2) which states that the spectral amplitude of the horizontal acceleration response spectra in the free field at the foundation depth shall be not less than 60% of the corresponding design response spectra at the finished grade Yh

in the free field, a site response analysis is performed with the program SHAKE to generate the acceleration time histories (and response spectra) at the free-field foundation level for each of the cases defined above and for each earthquake. Treating each case as a triplet, the three foundation level i response spectra are enveloped and the result compared with 60% of the surface spectra. If deficiencies exist that cannot be corrected by slight changes in soil properties, then the control motion will be altered. To do so, the power spectral density functions of the motions at the surface and foundation level are calculated. In the frequency ranges where the foundation level spectra do not meet the SRP 60% requirement, the corresponding frequencies of the foundation level power spectral density function are amplified by the square of the ratio of 0.6 times the surface spectral values to the foundation level spectral values at those noncomplying frequencies. The corrected power spectral density function can then be used to generate a new acceleration time history at the foundation level and, by convolution, a new design time history at the surface level that will fully  ;

comply with the 60% requirement. This procedure will minimize the conservatism added in the frequency ranges where the 60% requirement was originally met. Iterations are performed as necessary with the express intent of not adding unnecessary conservatism to the artificial time histories. All SRP Section 3.7 criteria are then reverified.

2.5 Implementation of the Substructure Approach in SSI Analysis The three remaining steps in the substructure approach (determining the foundation input motion, calculating foundation impedances, and modeling the structure) are discussed next. For this approach to be valid, one important assumption needs to be verified, i.e., that the foundation behaves rigidly with respect to the surrounding soil. This is the case for the PNPS Reactor Building due to the stiffness of the foundation itself and the effective stiffness of the interconnecting walls and slabs.

42103-R-001 Revision 0 July 30,1993 Page 16 of 79 ,

2.5.1 Foundation Inout Motion The foundation input motion differs from the free-field ground motion in all cases, except for surface foundations subjected to vertically incident waves.

The motions differ for two reasons. First, the free-field motion varies with soil depth. Second, the soil-foundation interface scatters waves because points on the foundation are constrained to move according to its ge7 metry and stiffness. The foundation input motion (u*) is related to the free-field  !

ground motion by means of a transformation defined by a scattering matrix

[s(w)], which is complex valued and frequency dependent:

{u' (w)} = [s(w)] {f(w)}

The vector {f(w)} is the complex Fourier transform of the free-field ground t motion, which contains its complete description.

As already discussed in Section 2.4, the three foundation level response ,

spectra corresponding to the foundation input motion from the three soil cases are enveloped and the result is compared to 60% of the surface spectra. If deficiencies exist that cannot be corrected by slight changes in ,

soil properties, then the control motion is altered.

2.5.2 Foundation Imoedances Foundation impedances [ks(w)] describe the force-displacement '[

characteristics of the soil. They depend on the soil configuration and material behavior, the frequency of the excitation, and the geometry of the i foundation, in general, for a linear elastic or viscoeleastic material and a f

uniform or horizontally stratified soil deposit, each element of the impedance

-l matrix is complex-valued and frequency dependent. For a rigid foundation, ,

the impedance matrix is a 6 X 6 which relates a resultant set of forces and l

, moments to the six rigid body degrees-of-freedom.

~ July 30,1993 Page 17 of 79 The embedment of the PNPS Reactor Building foundation is one of the most significant parameters on structure response, and modeling this embedment is essential. The computer code SUPELM (Reference 5) is used for this .

purpose. SUPELM is based on a rigid circular foundation embedded in a layered medium with infinite boundaries. These assumptions are appropriate for the PNPS Resc*or Building and equivalent properties are computed. EQE t

has verified St>FELM under its OA program by comparing to SASSI. SASSI is a well-known computer code which has been reviewed and approved by the NRC for its use in the nuclear industry and has been extensively used for nuclear projects. .

Horizontal ground motions are assumed to be composed of vertically propagating shear waves, and vertical ground motions are assumed to be composed of vertically propagating compressional waves. These assump-I tions are consistent with current practice and it has been demonstrated that  !

I they result in realist % structural and soil responses (Reference 3). )

l 2.5.3 Structure Model Depending on the end use of the SSI analysis, the dynamic model can exhibit various levels of refinement from a detailed member specific model to a single equivalent beam lumped mass model in addition, depending on the com- l l

plexity of the structure between floors (e.g., curved or skewed wall systems) detailed finite element models can be constructed to derive the equivalent beam properties (shear area, moments of inertia and center of rigidity) or i element stiffness matrices. The details of the PNPS Reactor Building model j are described in Chapter 3. .l i

Using an appropriate finite element model (i.e., a lumped mass equivalent beam model for spectra generation) the dynamic properties of the structure are described by the fixed-base eigensystem and the individual modal

_ r - .-.., _ _ ,

42103-R-001 Revision 0 July 30,1993 Page 18 of 79 1 damping ratios. The modal damping ratios are the composite viscous damping ratios for the fixed-base structure expressed as a fraction of critical damping. The structures' dynamic properties are then projected to a point on the foundation at which the total motion of the foundation, including SSI effects, is determined.

2.6 SSI Analysis The final step in the substructure approach is the actual SSI analysis. The results of the previous steps (foundation input motion, foundation impedances, and structure model) are combined to solve the equations of motion for the coupled soil-structure system. For a single rigid foundation, the SSI response computation requires the solution of, at most, six simultaneous equations - the response of the foundation. Solution is  ;

obtained by first representing the response in the structure in terms of the foundation motions and then applying that representation to the equation defining the balance of forces at the soil / foundation interface. The formulation is in the frequency domain. Hence, one can write the equation of motion for the unknown harmonic foundation response {ub} exp(io>t), for any frequency c), about a reference point selected on the foundation. The computer program SSIN is used to combine the several steps to give the final structure response.

The computer code CLASSI (Continuum Linear Analysis for Soil-structure Interaction) consists of a set of subprograms for analyzing the effect of soil-structure interaction on the response of structures. Basically, the CLASSI program may be divided into two parts, CLAN and SSIN, using a special 1

substructure method developed by Wong and Luco. The CLAN portion applies the theory of linear continuum mechanics to analyze the harmonic interaction between the rigid foundation mat and the underlying soil medium.

The information generated by CLAN is the impedance and scattering

42103-R-001 Revision 0 July 30,1993 Page 19 of 79 matrices. The impedance matrix describes the harmonic force-displacement relationship of the response to incident waves. The SSIN part of the program completes the substructuring process by combining the stiffness matrix of the structure at the base level and the impedance matrix to determine the unknown foundation motions and structural responses. For this project, SUPELM is used in place of CLAN, so only the SSIN portion of CLASSI is used. t Time histories generated in the SSI analysis are converted to floor response spectra for each of the three soil cases. The three floor response spectra in each direction are enveloped and then broadened and smoothed according to the requirements specified in SRP 3.7.2 and Regulatory Guide 1.122, considering however that uncertainties in soil properties and SSI will be included in the SSI analysis.  !

3. BUILDING MODEL i

3.1 Introduction This chapter presents an overview of the structural model of the Reactor Building and Internal structures used in the SSI analysis and response spectra generation. The development of the model is documented in Reference 7.

Figure 1-1 shows a schematic of the model with the mass points indicated. ,

Table 3-1 and 3-2 contain the nodal properties and element properties of the model.

3.2 Description of the Reactor Building and Internal Structures The Reactor Building is a rectangular reinforced concrete structure up to the refueling floor at EL.117. Above that it is a steel frame with exterior precast concroa panels.

The foundation mat is 144.5 feet square and 10 feet thick with the finished top surface at El. -17.5. It rests on a 6 inch thick concrete working slab.

There is an extension of about 40 feet by 60 feet on the northwest side comprising the HPCI compartment under the Auxiliary Bay. The exterior shape of the building is essentially rectangular for the remainder of its height, with an interior grid of walls between floor levels Figures 3-1 through 3-10 show cross-sections at different elevations. Site grade is at El. 23. The shear centers and centers of mass of the Reactor Building are not coincident over the height of the buil ding, introducing the potential for significant torsional response.

The drywell containment vessel is an axisymmetric steel structure surrounded by a reinforced concrete shield wall which follows the contour of the vessel from the foundation of the drywell up to the operating floor. The drywell

e. - 4 42103-R-001 Revision O July 30,1993 Page 26 of 79 shield is an integral part of the main building structure. The centerline of the drywell vessel is not coincident with the centerline of the reactor building.

The torus suppression pool is located below the drywell and is supported by the mat.

The reactor pressure vesselis sr 7 ported by a reinforced concrete pedestal inside the drywell. The vessel is surrounded by a biological shield wall built ,

up of welded steel sections and infill concrete. The biological shield is supported on the reactor pedestal. The pedestal and drywell are supported on a solid concrete section extending about 25 feet above the top of the mat.

The reactor pressure vessel, biological shield wall and drywell structures are braced to the Reactor Building structure at El. 81.8. The reactor vessel is braced to the top of the biological shield by a stabilizer system which resists lateral movement and torsion but not vertical movement (it also allows radial ,

growth, but this is not relevant to seismic response). The biological shield is braced to the drywell by the star truss which acts similarily to the stabilizer.

The drywell is connected to the drywell shield concrete by heavy steellugs which also restrain only lateral and torsional movement. ,

3.3 Model Stiffness Properties The floors of the Reactor Building are connected by a grid of walls and the

]

drywell shield structure. This irregular pattern makes it difficult to simulate  ;

l using composite beam e!cment properties. Therefore, finite element models l

were constructed to obtain stiffness properties. The models are shown in l Figures 3-11 through 3-15. All reinforced concrete walls extending from floor to floor with adequate length to develop shear resistance were included.

I Walls with small openings infil%d with block were considered continuous if it I was judged that the block infill would transmit shear. Full height reinforced block walls two feet or more thick were also included, although the modulus  !

l of elasticity was adjusted to reflect the lower stiffness of concrete block construction. The change in wall sections and the floor slab in the Auxiliary Bay at El. 3 was modeled explicitly in the finite element model from El. -17.5 to El.-23 (Figure 3-11). ,

The nodes at the top and bottom of the wall meshes were rigidly connected >

to nodes at the z-axis (reactor conterline). These nodes were then given unit displacements and rotations. Using the reaction forces, stiffness matrices j were assembled. The finite element models also yielded mass properties for the walls. These were distributed to the floors above and below in the mass property calculations.

The dryiNell lugs are connected to the Reactor Building at El. 81.8 which is between floors. The lugs are embedded in the drywell shield concrete. To model this connection a node (5) was introduced between El. 74.25 and -

91.25. This node was connected to the floors by beam elements representing the drywell shield cross-section. The stiffness of this cross-section was then subtracted from the stiffness matrix of the element connecting the two floors. This provided a good representation of the stiffness restraint for the drywelllugs while also providing a good representation of the stiffness between the two floor elevations. ,

The superstructure above the operating floor at El.117.0 consists of steel columns with exterior precast concrete panels. Investigation determined that  ;

the panels were adequately connected to the columns to provide shear  !

transfer. The stiffness properties were then determined based on a l

composite of the precast panels and the columns at the perimeter of the building. This could be well represented in the model by an equivalent beam element.

__ _ - _ _ _ _____J

I 42103-R-001 Revision 0 July 30,1993 Page 28 of 79 The torus structure was determined to be rigid based on review of drawings and References 11 and 12. It was modeled as four nodes around the circumference cf the vessel joined by rigid elements to the base mat center of '

mass. The m..ss properties of the torus were combined into the base mat mass properties.

The drywell vessel stiffness was calculated assuming that it consists of a series of cylindrical sections. This simplification was considered acceptable because the drywell is light and stiff relative to the overall building and is >

connected at the top and bottom. The approximation as a series of cylinders somewhat underestimates the stiffness; thus, the approximation is conservative. The drywell lugs which connect the drywell to the drywell shield structure were simulated with high stiffness values since the lugs are very stiff.

The stiffness properties of the biological shield, reactor vessel and reactor pedestal were taken from prior work by Bechtel and General Electric (References 9 and 10). The documentation of this was reviewed and felt to ,

be acceptable. Likewise, the stiffnesses of the star truss and stabilizer were taken from this documentation. The torsional stiffnesses for the star truss .

and stabilizer were estimated using the lateral (tangential) stiffness and mean radius between the connected structures.

3.4 Model Mass Properties The Reactor Building mass was lumped at eight locations corresponding to the main floor levels, the crane rail elevation and the roof. Mass properties of the floors were determined using finite element representations. The weights of the concrete, steel framing, secondary walls, platforms and major equip-ment were combined to determine the total mass. Allowances for piping, miscellaneous equipment and live loads were added to the mass based on i

judgment. Judgments are acceptable because the dynamic response is not sensitive to moderate changes in these parameters. This was then spread cy I

1 42103 R 001 I Revision 0 July 30,1993 Page 29 of 79 over the floor area to determine the centroid and mass moments of inertia.

The centroid, mass, and mass moments of inertia of the primary walls were ,

determined in the stiffness calculations and distributed to the floors above and below. The floor and wall properties were then combined to determine the not mass, centroid, and mass moments of inertia. Macsless nodes were specified at the extreme corners of the floors for use in obtaining torsional 3

effects. The final response spectra were an envelope of the spectra from the centroid and the extreme points.

The Auxiliary Bay was included in the model because it is integral with the Reactor Building. This was not done in the original analysis. A review of the Radwaste and Turbine Building drawings and Reference 8 showed that these are not integral with the Reactor Building. However, certain portions of the buildings are supported on the Reactor Building, and a suitable portion of this mass was included in the model.

The following interface locations were considered:

1

  • Reactor Building Auxiliary Bay Roof (El. 50)

. Turbine Building El. 50

= Turbine Auxiliary Bay Roof (El. 82) e Radwaste Building Roof (El. 51)

All other interface points (e.g., Turbine Building El. 23 and 37, Radwaste Building El 37) have insignificant mass contribution. The mass contribution -

of these areas were considered covered by the dead load allowances used at these floor levels.

The mass properties for the drywell were calculated based on the weight of the spherical or cylindrical sections. Because the rotational inertias would have negligible effect on the response of the model, they were not calculated.

I 42103-R-001 Revision 0 July 30,1993 Page 30 of 79 The mass properties of the biological shield, reactor vessel and reactor pedestal were taken from prior work by Bechtel and General Electric (Reference 9 and 10). The mass of the reactor internals was condensed and lumped at the point of connection with the vessel. This simplification was considered acceptable because the high stiffness of the vessel would isolate it from effects of the internals. This was supported by examination of the original vessel spectra in Reference 10 which showed a single predominant peak at the fundamental Reactor Building frequency.

3.5 Element Damping Dampings of different portions of the model were selected based on the materials involved. Dampings for the Reg. Guide 1.60 input cases were taken from Reg. Guide 1.61. Dampings for the PNPS FSAR input cases were taken from the original PNPS FSAR, but were adjusted as judged appropriate for use with Housner spectra.

The Reactor Building main structure was considered reinforced concrete including the superstructure. The superstructure was considered reinforced concrete because the main earthquake resisting elements are the precast panels attached to the exterior building columns. For the PNPS FSAR input cases, damping ratios of 5% for SSE and 2% for OBE were used rather than 7.5% and 5% as specified in the PNPS FSAR. The values used were judged more appropriate for use with Housner spectra.

The drywell was considered a welded steel structure per Reg. Guide 1.61 or welded assembly per PNPS FSAR. The biological shield wall was considered a welded steel structure per Reg. Guide 1.61 (this is conservative) or internal concrete structure / equipment support per PNPS FSAR. The pedestal was assigned the same damping as the shield wall. This is conservative, but the l

S, hih)h

l 4 2103-R-001 Revision 0 July 30,1993 Page 31 of 79 pedestal would not be subject to high earthquake stress; hence, lower damping than the standard for reinfoned concrete is appropriate. The reactor vessel was considered equipment /large diameter piping per Reg.

Guide 1.61 or welded assembly per PNPS FSAR. The values used for the PNPS FSAR input cases agree with those used in Reference 10.

The element damping ratios are summarized below:

Element Damping Ratio (Percent)

Reg. Guide 1.60 PNPS FSAR SSE OBE SSE OBE Reactor Building 7 4 5 2 Drywell 4 2 2 1 Bio-Shield & Pedestal 4 2 3 2 Reactor Vessel 3 2 2 1 3.6 Floor Flexibility Floor sections in the Reactor Building main structure were checked for flexibility and potential for resonance in the vertical direction of excitation.

Four sections were checked at El.117, three at EL. 91.25 and one at El.

74.25. These were judged to be the bounding cases for all elevations. The frequencies were calculated using composite concrete-steel clastic cross-sections continuous over supports (i.e., fixed end boundary conditions). The calculated frequencies ranged from 22.7 Hz. to 47.3 Hz. Since the predominant vertical response of the coupled soil-structure system for the main building structure was expected to be below 10 Hz., local floor resonance potential was judged not significant and special modeling was not necessary.

4. ANALYSIS RESULTS 4.1 Time Histories i Three statistically independent ground motion time histories were generated for each carthquake case and their spectra compared to the target spectra.

These comparisons, at the surface and at the foundation level, are shown in . Figures 4-1 to 4 5 for the Reg. Guide 1.60 SSE. Power spectral density functions for the time histories are shown in Figures 4-6 to 4-7. 4.2 Building Model Frequencies The first 30 fixed base frequencies and composite damping ratios for the , Reactor Building dynamic model are given in Table 4-1. The percent mass participating in each direction is also shown. The frequencies in Hertz of the first significant modes for the main building portion of the modelin each direction are shown below and compared to those calculated by EQE using the original Bechtel models (Reference 15): New Model Old E-W Model Old N-S Model Direction Frequency Frequency Frequency r N-S 5.04 5.61 , E-W 6.36 5.79 Vertical 14.66 14.96 13.78 Composite modal damping ratios were computed using the stiffness weighting function method of Reference 2. 4.3 Soil Impedances and Scattering Functions The soilimpedances and scattering functions were computed using the low strain soil layer properties provided in Reference 13. These are shown in Table 4-2. A weighted average, effective embedment of 31.5 feet was used. . 1 Impedances and scattering functions were computed for best estimate, upper ) bound (best estimate times 2.0) and lower bound (best estimate divided by Ex:g Sh l

42103-R-001 ' Revision 0 July 30,1993 Page 55 of 79 2.0) soil properties for the R.G.1.60 SSE and PNPS FSAR (Housner) SSE cases. The best estimate impedances are shown in Figures 4-8 to 4-15 for  ! R.G.1.60 SSE. The scattering functions are shown in Figures 4-16 to 4-20. Because of smooth variations in the soil properties, the impedances and scattering functions for the upper bound and lower bound OBE cases could be scaled from the calculated impedances and scattering functions for the best estimate OBE cases. 4.4 In-Structure Response Spectra The coupled soil-structure system was analyzed for seismic response. In-structure response time histories were calculated at the required node points for each direction of input for each soil case. Directional responses could be combined algebraicly because the input time histories were statistically independent. Response spectra were generated at the nodes, for each , direction, for each soil case. The spectra were broadened. Regulatory Guide 1.122 specifies that the broadening ratio shall be determined by varying parameters but shall be at least 10%. A ratio of 15% may b3 used in lieu of varying parameters. In this analysis, the only parameters whose variance , would significantly affect the building frequency are the soil properties. To , be conservative, each soil case was individually broadened using a broadening factor of 15% for the best estimate soil case and 10% for the i upper and lower bound soil cases. The spectra for the three soil cases were

  • then enveloped. Finally, for the Reactor Building floors outside containment and the torus, spectra at all the points at the same elevation were enveloped.

The final in structure response spectra for R.G.1.60 SSE input are contained in Attachment A to this report. The in-structure response spectra for other cases may be found in Reference 14. The analysis is documented in Reference 14. l

More than 16 of those years have been spent in the analysis and design of nuclear power plant l structures, piping, and components. !!c is expert in the areas of structural dynamics, seismic qualifica-tion, finite element analysis, structural behavior, and reinforced and prestressed concrete design. - Dr. Bjorkman has provided expert testimony before the Atomic Safety and Licensing Board on finite  ! element modeling and dynamic analysis of civil structures, piping systems and raceways and has made j numerous presentations to utility management and the NRC staff. In addition, he has twice been a Principal Research Investigator for the National Science Foundation working on inverse problems in mechanics and stress concentration minimization. This research lead to the discovery ofilarmonic Shapes, which are a class of hole and inclusion geometrys that are invisible to La Placian fields. Dr.13jorkman is currently involved in several projects. These include:

  • Independent review of a design basis analysis for a Fuel Storage Facility.
  • Develoirment and implementation of a 42 hour traimcg program on Seismic Equipment Qualification.
  • Operability Evaluation of a spent fuel pool.
  • Development of a Reactor Building dynamic model and generation of design floor response spectra using state-of the art soil structure interaction methods.
  • Independent review of the structural aspects of replacing steam generators through the primary containment dome.

Recently, Dr. Bjorkman completed teaching a 28 hour training course on Structural Dynamics and Seismic Analysis for Rochester Gas and Electric's Civil / Structural, Mechanical, and Site Support Staff. The course stressed the fundamental simplicity of structural dynamics,its link to the finite element method, and its relationship to the overall seismic analysis process, as applied to nuclear power plant facilities. In the area of piping, topics such as rass point spacing and missing mass were discussed and illustrated in detail. Issues related to A-46, such as anchorage flexible and in-cabinet amplification,were discussed and demonstrated using EQE's direct generation software, EQE FSG, the ANSYS program, and the response spectra database management program, SpectraDb.

t . .> GORDON S. BJOIWMAN,.lR. PROFESSIONAL EXPERIENCE (Continued) For Carolina Power & Light, Dr. Bjorkman performed an evaluation of pitstress losses in the large girders which support the spent fuel pool. lie also determined the root cause of cracks in the bottom of the spent fuel pool slab which had puzzled CP&L and its consultants for a number of years. At ABB Impell, Dr. Bjorkman was Technical Manager for the Engineering Mechanics Division. Ile was , Project Engineer for the resolution ofGeneric Letter 87-02/ Unresolved Safety issue A 46 at Northeast Utilities' Connecticut Yankee, and Millstone Units 1 and 2 stations. For Rochester Gas and Electric's Ginna Station, Dr. Bjorkman developed a strategy to address NRC concems regarding the behavior and integrity of the neoprene joint detail between the venically prestressed containment shell and basemat. Using an axisymmetric ANSYS model, which extended from below the prestressed rock anchors to the containment dome, and a 180' containment shell model, Dr. Bjorkman investigated numerous limiting boundary conditions including slip between the various concretc/ rock interfaces and failure of radial tension ties. In addition, dynamic analysis using the shell model substantiated the original seismic design basis for the containment. Dr. Bjorkman's presentation before the NRC staff and subsequent discussiuns resolved the NRC's concerns and allowed RG&E to obtain a three year extension to their operating license. At GPU Nuclear's Oyster Creek Plant, cracks in the concrete girders supporting the spent fuel pool (SFP) prompted safety concerns for the storage of high density racks. To address the safety concerns, Dr. Bjorkman developed a nonlinear analysis strategy to account for the redistribution ofinternal forces caused by concrete cracking due to mechanical and thermal loads. To implement the nonlinear strategy and to account for force redistribution within the entire reactor building structure, a large ANSYS model, consisting primarily of solid elements, was carated. The results showed that the location and orientation of existing cracks in the girders, SFP walls, reactor shield wall, and operating floor slab were predicted by the analysis, and that the high density rack loads were within the load carrying capacity envelop of . the SFP and its supporting members. Prior to these projects, Dr. Bjorkman was Project Consultant to the Three Mile Island 1 Skcwed Pipe Clamp Evaluation Project.1-le developed project instructions and special criteria for the nonlinear (gaps and friction) analysis of pipe clamps, as well as an evaluation methodology for pipe wall stresses when lug-induced stresses exceed Code Case N-318 values. This project was highly successful and resulted in i no modiScations to any of the 56 clamps involved. s in support of the Nine Mile Point Unit 1 (NMP1) restan effort, Dr. Bjorkman performed a structural integrity investigation to determine the signincance of 1,400 pipe support deSciencies found during the ISI Program. In addition, he performed an extensive technical quality review for the NMP1 static and  ; dynamic finite element building models, which ranged in size from 2,000 to 60,000 degrees-of-freedom l and which will be used during NMPI's Design Basis Reconstitution Program. For Rochester Gas & Electric, Dr. Bjorkman developed an innovative methodology to inexpensively analyze, evaleate, and qualify the major braced column line between the turbine and intermediate buildings,which other consultants' evaluations (NUREG 1821) had reported to be significantly overstressed under safe shutdown canhquake loads. Dr. Bjorkman's final repon was submitted directly to the NRC by Rochester Gas & Electric and resolved the scismic safety issue. Based on the success of Dr. Bjorkman's 1981 training program on piping system analysis, Virginia .t Power's Civil Stmetures Group asked him to return in 1987 to deliver a 40-hour training program on structural dynamics. Complete example prob! cms of actual Virginia Power buildings were developed on  ! the STARDYNE computer program and were used to demonstrate the finite element modeling of structures for dynamic applications. e .,
