Subject:
McGuire Nuclear Station Docket Numbers 50-369 and -370 Catawba Nuclear Station Docket Numbers 50-413 and -414 FSAR Transient Analysis Methodology; Topical Report DPC-NE-3002-P Attached for your review is Duke Power Company's Topical Report DPC-NE-3002, "FSAR Cnapter 15 System Transient Analysis Methodelogy."
This report describes Duke's methodology for conservatively modeling those FSAR Chapter 15 non-LOCA transients and accidents not previously described in DPC-NE-3000, " Thermal-Hydraillic Transient Analysis Methodology" and DPC-NE-3001,
" Multidimensional Reactor Transients and Safety Analysis Physics Parameters Methodology._" This report is applicable to the McGuire and Catawba Nuclear Stations.
The objectives of this report are: 1) to describe the initial and boundary conditions and input assumptions regarding control and protective system functions, as used in the analysis of FSAR Chapter 15 events; and 2) to describe nodalization and/or modeling differences relative to those analyses previously detailed in DPC-NE-3000.
The rod ejection, steam line break, and dropped rod methodologies are described in DPC-NE-3001, and are not discussed in this report.
Assumptions regarding safety analysis physics parameters are also discussed in DPC-NE-3001.
Please note that approval of this Topical Report is needed for startup of McGuire Unit 1 Cycle 8 following its upcoming refueling outage.
The outage is scheduled to begin in late September, 1991.
Cycle 8 is expected to start up in late November or early December.
