NuScale Response to NRC Request for Additional Information eRAI No. 8932
NuScale Nonproprietary Response to Request for Additional Information Docket No.52-048 eRAI No.: 8932 Date of RAI Issue: 07/31/2017 NRC Question No.: 03.07.02-6 10 CFR 50 Appendix S requires that the safety functions of structures, systems, and components (SSCs) must be assured during and after the vibratory ground motion associated with the Safe Shutdown Earthquake (SSE) through design, testing, or qualification methods.
DSRS 3.7.2 provides guidance that effects of potential separation or loss of contact a.
between the structure and the soil during the earthquake should be considered in SSI analysis. On Page 3.7-23 of the FSAR, in the second paragraph from the bottom, the applicant states, To model the soil separation, the Young's modulus of the backfill elements down to a depth of 25 (the top four layers of backfill elements) was decreased by a factor of 100. The applicant is requested to provide a basis for 25 ft of separation depth.
Also, please clarify if the modulus reduction by a factor of 100 applies only to the backfill elements interfacing with the exterior walls or to all the backfill elements outside the exterior walls.
On Page 3.7-23 of the FSAR, in the bottom paragraph, the applicant states, Soil b.
separation has negligible effect on the response of the structure. The primary point of comparison is at the NPM. The study showed that the maximum reaction force at the base of the NPMs decreased by approximately 5 percent, and the maximum reaction force at the NPM lug restraints decreased by more than 15 percent. The applicant is requested to provide information on soil separation effect on computed transfer functions and seismic demands (forces, ISRS) at critical section locations and external walls. Please provide comparison plots for results between the intact and soil-separated cases. When soil-separation results in increased seismic demands, such increased demands should be taken into account in establishing the design basis seismic demands.
The staff notes that a soil-separation study was conducted for the RXB but not for the c.
CRB. The applicant is requested to provide a technical justification for not conducting a similar study for the CRB.
NuScale Response:
- a. The soil separation depth of 1/3 the embedment depth was chosen based on the fact that
NuScale Nonproprietary the Reactor Building (RXB) and Control Building (CRB) are deeply embedded structures and are surrounded by engineered, compacted backfill.
In addition, ASCE 4-98, Section 3.3.1.9, indicates that a method to address soil separation is to assume no connectivity between the structure and lateral soil over the upper half of the embedment, or 20 feet, whichever is less. Given the model element sizes, 25 feet was a more convenient depth rather than the ASCE 4-98 stipulation of 20 feet.
Also note that the soil separation zone only applies to cohesive soils, where the lateral soil pressure at the top of the wall, down to a certain depth, is negative, creating a tension zone (separation zone) between the wall and the soil. For the NuScale reactor and control buildings, all FSAR soil cases are cohesionless, i.e., the lateral soil pressure at the top of the wall is zero, and increases with depth, meaning, physically, there will be no soil separation.
The soil modulus is reduced for the full width of the backfill soil, 25.
- b. Spectral acceleration transfer functions and ISRS at critical locations are provided below.
Overall, there is very little difference between the transfer functions and ISRS of the two models.
Additionally, forces at the NuScale Power Module (NPM) lug supports, soil pressures on the external walls, maximum shears and moments in exterior walls and two pilasters, and total vertical base reaction results are presented. There are some instances where the design loads increase due to soil separation effects. However, the design margins of the RXB structural members are such that these increases do not affect the building design.
- c. A soil-separation study has been conducted for the CRB. Conclusions similar to those of the RXB were reached, i.e., the spectral acceleration transfer functions and ISRS at critical locations between the two models are similar, increases in forces due to soil separation are within design margins of the building components, leaving the building design unaltered.

NuScale Final Safety Analysis Report Seismic Design Tier 2 3.7-113 Draft Revision 2 the bending stiffness in half for the cracked concrete condition. In this approach, the uncracked axial stiffness is reduced by a factor of 0.7937.
Soil Separation A study was performed to investigate the effects of a gap forming between the RXB and the backfill soil during an earthquake.
The RXB was analyzed for Soil Type 7 with cracked concrete properties and 7 percent concrete material damping. Soil Type 7 was chosen because that is the case that produced the highest ISRS and forces and moments at the majority of the locations. Cracked concrete properties were chosen to be consistent with the use of 7 percent damping for the concrete material.
To model the soil separation, the Young's modulus of the backfill elements down to a depth of 25 (the top four layers of backfill elements) was decreased by a factor of 100.
RAI 03.07.02-6 Soil separation has negligible effect on the response of the structure. The primary point of comparison is at the NPM. The study showed that the maximum reaction force at the base of the NPMs decreased by approximately 5 percent, and the maximum reaction force at the NPM lug restraints decreased by more than 15 percent. In addition to examining the forces on the NPM, the in-structure response spectra were compared at the top of the basemat and the roof of the building. The ISRS virtually overlay each other, comparable in shape, and peak of response. Therefore, based upon the results of this study, modeling the structures as fully embedded is an acceptable design approach.The following responses and transfer functions calculated without soil separation are compared with those calculated with soil separation:
RAI 03.07.02-6 Forces at RXM Lug Supports The comparison indicates that the lug support reactions with soil separation are lower than those without soil separation. See Table 3.7.2-39.
RAI 03.07.02-6 ISRS and TFs at Selected Locations The comparison of the spectral acceleration transfer functions (TF) at selected locations indicates a few spurious spikes in the high frequency ranges that have no effect on the corresponding ISRS. See Figure 3.7.2-130 through Figure 3.7.2-135.
RAI 03.07.02-6 Soil Pressures on Walls The comparisons show that there are increases in the average pressures.
However, there is no increase in the maximum forces and moments in the walls.
NuScale Final Safety Analysis Report Seismic Design Tier 2 3.7-114 Draft Revision 2 RAI 03.07.02-6 Maximum Shears and Moments in Exterior Walls and Two Pilasters The maximum out of plane (OOP) shear remains about the same. The maximum OOP moment decreases about 10% due to soil separation. See Table 3.7.2-40.
The total vertical base reaction remains essentially unchanged. See Table 3.7.2-42.
RAI 03.07.02-6 The ISRS, displacements, and demand forces and moments due to soil separation effects investigated above are within the design capacities.
Therefore, the effect of backfill soil separation is covered by the available design margin and has no effect on the overall RXB design.
RAI 03.07.02-6 A soil-separation study was also done for the CRB. To account for the effect of partial soil separation in the analysis model for the study, the Youngs moduli of the backfill soil solid elements down to 1/3 of the embedment, which is approximately equal to the total thickness of the top three layers of backfill soil (18.75), were factored by 1/100. Conclusions similar to those of the RXB were reached, i.e., the spectral acceleration transfer functions and ISRS at critical locations between the two models virtually overlay one another, increases in forces due to soil separation are within design margins of the building components, leaving the building design unaltered. See Figure 3.7.2-136 through Figure 3.7.2-141 and Table 3.7.2-41 and Table 3.7.2-43.
RAI 03.07.02-6 Based on the results of these studies, it is concluded that modeling the structures as fully embedded is an acceptable design approach.
3.7.2.1.2 Finite Element Models RAI 03.07.02-1 Meshing of the area elements was done automatically using SAP2000 by defining a maximum element size in each direction. The aspect ratios were also kept as low as possible (closer to square shape), and internal sharp angles were avoided.
RAI 03.07.02-1 Meshing for both the RXB and CRB models were refined further, and it is shown that further refinement does not affect the structural response. The mesh refinement was done by dividing each side of the area elements into two, breaking each element to four elements. The structural responses compared include both local and global responses of the structure. The comparison shows that effects of further mesh refinement on the structural response is negligible. In addition to the modal analysis, to compare the natural frequencies and mass participation ratios, static analysis cases due to 1g loading in the x, y or z directions were used to make
