WESTINGHOUSE NON-PROPRIETARY CLASS 3 viii Executive Summary A high-cycle fatigue evaluation of the Westinghouse replacement steam dryer for the Monticello plant has been completed with loads generated using acoustic circuit enhanced (ACE) Rev. 1. Acoustic loads and stresses for 98% of current licensed thermal power (CLTP) and 100% of extended power uprate (EPU) conditions have been evaluated for high-cycle fatigue and have been determined to meet the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV) Code Section II, Subsection NG criteria.
The results from these analyses indicate that for the Monticello replacement steam dryer at EPU operation, the minimum high-cycle fatigue stress ratio anywhere on the steam dryer is [ pc and occurs on the [ 1ac These results account for all the end-to-end biases and uncertainties in the loads model and finite element analysis.

WESTINGHOUSE NON-PROPRIETARY CLASS 3 1-1 1 INTRODUCTION In 2002, after increasing power to 117% of the original licensed thermal power, the steam dryer in a boiling water reactor (BWR) experienced a series of structural failures. After extensive evaluation by various industry experts, the root cause of the dryer failures was determined to be acoustic fluctuating pressure loads on the dryer, resulting from resonances produced by steam flow in the main steam lines (MSLs) across safety and relief valve inlets. The failures in the steam dryer of a BWR led to changes in Regulatory Guide (RG) 1.20, requiring plants to evaluate their steam dryer before any planned increase in power level.
The Monticello power plant has contracted Westinghouse for a replacement steam dryer and is also planning a power uprate. In conjunction with the component replacement by Monticello and the planned power uprate, an analysis has been performed to qualify the replacement steam dryer, shown in Figure 1-1, for acoustic pressure loads. The process used to perform the analysis involves [
]"C Structural qualification of the replacement dryer for the remaining duty cycle of events applicable to the Monticello operating system is documented in Reference 1.

WESTINGHOUSE NON-PROPRIETARY CLASS 3 2-1 2 METHODOLOGY 2.1 OVERVIEW An analysis has been performed to assess the structural integrity of the replacement dryer for the Monticello plant subject to acoustic loads.
la,c 2.2 DESIGN REQUIREMENTS 2.2.1 1 Ia,c The replacement dryer is analyzed according to the 2004 Edition of the ASME B&PV Code, Subsection NG (Reference 2). This report documents the suitability of the replacement dryer for high-cycle fatigue loads resulting from acoustic loads. The governing criterion for the analysis is in terms of the allowable component fatigue usage. The objective of this analysis is to show that the maximum alternating stress intensity anywhere in the dryer is less than the material endurance strength at 10" cycles. The applicable fatigue curve for stainless steel (the dryer is manufactured from SS316L), is shown in Figure 1-9.2.2 in Appendix I of the ASME Code. The evaluation of the replacement steam dryer for non-acoustic loads is documented in Reference 1.
[
]a~c 2.2.2 Young's Modulus Correction Before comparing the maximum alternating stress intensity to the ASME Code endurance strength, it is necessary to account for the Young's modulus correction. The analysis uses a Young's modulus of 25.425 x 106 psi, compared to the value to construct the fatigue curves of 28.3 x 106 psi. The ratio that is applied to the calculated alternating stress intensities is 1.113 (i.e. 28.3 / 25.425).

WESTINGHOUSE NON-PROPRIETARY CLASS 3 4-1 4 MATERIAL PROPERTIES A summary of the material properties used in the structural analysis is summarized in Table 4-1. Material properties are taken from the ASME Code, Reference 4, for SS316L at a temperature of 575°F. The density of the skirt material below the water is increased to account for hydrodynamic effects of the water.
The perforated plates, located at the entrance to the vane banks, are modeled with equivalent plate properties to account for the reduced stiffness and mass of the plates. The density of the solid block representation of the vane banks is adjusted to achieve the correct overall mass of each vane bank.
4.1 STRUCTURAL DAMPING Structural damping is defined as 1% of critical damping for all frequencies. This damping is consistent with guidance given on page 10 of NRC RG- 1.20 (Reference 5). Using the harmonic analysis approach, a consistent damping level is used across the frequency domain.

As a result of approximations of the structural interactions used in developing the FEM, small errors can result in the prediction of the component natural frequencies. Varying degrees of mesh discretization can also introduce small errors in the FEM results. To account for these effects, frequency scaling is applied to the applied load-history.
