11.2.16 Fuel Rods Structural Evaluation for Burnup to 62,500 MWd/MTU

This section presents a structural evaluation of PWR and BWR fuel rods with a maximum burnup of 62,500 MWd/MTU for normal and accident conditions of storage.

During normal and off-normal conditions for the fuel in the canister, the loads applied to the fuel assembly are minimal and do not require further evaluation. The only significant axial loading the fuel assembly will experience is the 24-inch drop of the vertical concrete cask. The bounding lateral loading on the fuel assembly occurs during the tip-over accident condition. As presented in Section 11.2.16.1, the lateral loading and axial loading conditions are evaluated for PWR fuel rods considering a bounding configuration of a grid spacer missing for an unsupported fuel rod length up to 60 inches. Based on results of the drop analysis presented in the following sections, PWR fuel assemblies with one or more grid spacers missing or damaged for an unsupported fuel rod length up to 60 inches are, therefore, considered to be undamaged assemblies for loading within the UMS Universal Storage System. Section 11.2.16.2 presents the evaluation for the BWR fuel rods for the end drop and tip-over accident events.

11.2.16.1 PWR Fuel Rod Evaluation

End Drop Evaluation This section presents the buckling evaluation for the UMS Universal Storage System high burnup PWR fuel rods (peak rod average burnup of 62.5 GWd/MTU). In order to account for the cladding oxide layer, a conservative 120-micron thick layer is assumed to be removed from the reference clad in the rod structural evaluation. The 120-micron clad removal is conservative, as this value represents double the maximum oxide layer thickness listed for end-of-life PWR fuel rods in PNL-4835[62]. Applying a time-dependent oxide layer growth approximation to the PNL-4835-reported maximum thickness of 60 microns to account for an increase in burnup from standard (45 GWd/MTU) to high (62.5 GWd/MTU) yields a maximum end-of-life oxide layer in the range of 90 microns. As high burnup claddings are designed to reduce oxidation, actual layers are expected to be significantly lower (reported as low as 20 microns for >70 GWd/MTU M5 zircaloy clad). Therefore, a significant margin exists to the evaluated oxide layer levels.

A 24-inch end drop of the concrete cask subjects the fuel rods to axial loading. The analyses in this section show that the maximum stresses in the high burnup PWR fuel remain below the yield strength in the design basis accident events and confirm that the fuel rods will return to their original configuration following the end drop event.

The case using the 60-inch spacing in conjunction with the minimal cross-section (Case 3) is identified as the bounding case. All stresses were shown to be less than the yield strength.

The results confirm that high burnup PWR fuel with a maximum distance of 60 inches from the bottom to the first grid will remain structurally adequate for the storage design basis cask end drop load conditions.

Tip-Over Evaluation

11.2.16-4 NAC PROPRIETARY INFORMATION REMOVED FSAR - UMS Universal St orage System September 2023 Docket No. 72-1015 Revision23A

Stresses are evaluated against the cladding yield stress at a bounding fuel temperature of 752°F (400°C) to compute margins of safety. The minimum margins of safety in the three cladding materials all occur in the BW17x17 Mark C fuel rod and are summa rized in the following table.

Therefore, the PWR high burnup fuel rods remain structurally adequate during the cask tip-over accident event.

11.2.16.2 BWR Fuel Rod Evaluation

This section presents the structural evaluations of the BWR high burnup fuel assemblies for the cask 24-inch end drop and tip-over accident conditions. The high burnup BWR fuel is considered to have a cladding oxide layer of 125 microns thick. A reduced cladding thickness is assumed due to the cladding oxide layer.

End Drop Evaluation In the end drop orientation, the fuel rods are laterally restrained by the grids and come into contact with the fuel assembly base. The fuel assembly is considered to have an initial of bow of 0.157 inch [64]. The evaluation of the BWR fuel rod is based on the following representative samples of BWR fuel assemblies:

BWR Fuel Cladding Cladding Fuel Rod Gap between fuel Assembly Diameter (in) Thickness Pitch assembly and fuel (in) (in) tube wall (in) 8X8 0.483 0.032 0.64 0.937 9X9 0.433 0.026 0.572 0.891 10X10 0.396 0.024 0.51 0.914

Review of the design basis fuel inventory indicates that the largest gap between the envelop of the fuel rods of a straight fuel assembly and the basket fuel tube inner wall could be 0.937 inch.

In this evaluation, an assembly with an initial bow of 0.157 inch is permitted to displace an additional 0.78 inch to the full gap displacement of 0.937 inch. To implement a bow of 0.157 inch into the fuel assembly, the half symmetry ANSYS model corresponding to a row of fuel rods (Figure 11.2.16-4) is used. The clad is modeled with shell elements (see Figure 11.2.16-5).

Each grid is modeled using brick elements to maintain the spacing between the fuel rods at the grid. The fuel tube is modeled using brick elements to restrict the lateral motion of the fuel assembly. Each of the fuel rods in the ANSYS model is simply supported at each end. A static force is applied to the ANSYS model at the grid nearest the axial center to develop a 0.157 inch lateral displacement. The purpose of the ANSYS model and solution is to provide the coordinates of the fuel clad for the LS-DYNA model. This is accomplished by obtaining a static solution with the ANSYS model, and then using the option to update the coordinates of the nodes based on the displacements from the solution.

11.2.16-9 NAC PROPRIETARY INFORMATION REMOVED FSAR - UMS Universal Storage System September 2023 Docket No. 72-1015 Revision23A

Three (3) LS-DYNA models are considered for the 24-inch cask end drop conditions. All models incorporate a bow of 0.157 inch. These cases envelope the range of the cross-sectional moment of inertia for the BWR fuel rods and the largest grid spacing of the fuel assembly are summarized in the following Table.

Case Fuel Assembly Largest grid spacing (inch) 1 8x8 23.61 2 9x9 22.28 3 10x10 22.57 In each case the thickness of the clad was reduced by 125 microns (0.0049inch). Each case requires a separate ANSYS model and a LS-DYNA model to represent unique coordinates or boundary conditions. The LS-DYNA model employs the same nodes and elements as the ANSYS model (with the incorporation of the 0.157 inch bow). Elastic properties are used in the ANSYS model and the bilinear properties are employed in the LS-DYNA model. An initial downward velocity of 136 in/sec (corresponding to a 24-inch end drop of the storage cask) is assigned to all nodes in the model. The deceleration time history is applied to the nodes of the brick elements representing the fuel tube. The acceleration time history is obtained from the analysis for the 24-inch drop of the VCC in Section 11.2.4. The side walls of the fuel tube are restrained in the lateral direction to maximize the effect of the fuel rods impacting the fuel tube side wall.

The LS-DYNA analyses for Cases 1 through 3 were performed for the duration of 0.08 second to capture the response of the fuel after the 0.02 second loading duration. Post-processing each analysis result identifies the maximum shear stress occurring at the shell surface. The maximum shear stress result from LS-DYNA is factored by two to determine the maximum stress intensity.

The following table contains the maximum stress intensity and the margin of safety (M.S.) for

All stresses are shown to be well below the yield strength. The results confirm th at high burnup BWR fuel will remain structurally adequate for the storage design basis cask end drop load condition.

Detailed view of the axial section of the fuel assembly

The gap between the assembly and the side is reduced by 0.157 inch to simulate the bow in the fuel assembly.

All shell elements were modeled at the midplane thickness of the clad. The LS-DYNA interface takes into account the thickness of the shell element when determining the contact.

Brick elements for the grid.

A small gap (0.01 inch) was modeled between the fuel rod and bottom brick elements

Brick elements representing the sides of the fuel tube.

The deceleration time history was applied to nodes of these brick The nodes in the elements bricks for the sides and the bottom are restrained in the lateral direction

11.2.16.3 Thermal Evaluation of Fuel Rods The UMS system limits normal storage condition fuel cladding temperatures to levels below zirconium alloy or stainless steel cladding temperature limits; therefore, degradation is not expected to occur below this temperature in an inert gas environment.

As shown in Chapter 4, fuel cladding temperature limits for PWR and BWR fuel rods have been established at 400°C (752°F) for normal and off-normal conditions of storage, including transfer operations, and 570°C (1,058ºF) for accident conditions. Chapter 4 demonstrates that the maximum fuel cladding temperatures are well below the temperature limits for all design conditions of storage.
