SUMMARY

In the spring of 2011, Westinghouse installed a replacement steam dryer (RSD) at the Monticello Nuclear Generating Plant (MNGP). For this project, the RSD was equipped with a comprehensive instrumentation package, including pressure transducers, strain gauges, and accelerometers. Plant data were obtained for several power levels between zero power and current licensed thermal power (CLTP), or 1775 MWt. The new steam dryer was designed to allow MNGP to uprate the reactor power to 2004 MWt. In order to qualify the steam dryer for the extended power uprate (EPU) conditions, a structural evaluation was required to verify the integrity of the component when subjected to acoustic loads.

1-1 a0 Ia~c a~c All the techniques and model parameters developed during the benchmarking process of ACE Revision 2.0 will be used consistently in the application of the methodology to qualify the RSD at EPU conditions.

2-1 2 ACE REVISION 2.0 DIGITAL SIGNAL PROCESSING METHODOLOGY The DSP procedure developed for ACE Revision 2.0 addresses analysis and conditioning of the input signals for both the main steam line (MSL) and steam dryer data. In particular, the following aspects are part of the DSP approach:
