Content:
piping from the seismic interface restraint up to, but not including, the turbine stop valve (including branch lines to the first normally closed valve) and steam drain line piping from the outermost containment isolation valve to the condenser hotwell, should be classified and analyzed as described in 4.c below. All pertinent quality assurance requirements of Appendix B to 10 CFR Part 50 apply to the main steam line piping from the seismic interface restraint up to, but not including, the turbine stop valve (including branch lines to the first normally closed valve). BTP 3-1-6 Revision 2 - March 2007 Table A-1 (continue) c. These components may be classified as nonsafety-related and non-seismic Category I but should be analyzed using a dynamic seismic analysis method to demonstrate structural integrity under safe shutdown earthquake (SSE) loading conditions. The dynamic input for such analyses should be derived from time history analyses of the buildings (e.g., turbine building). Alternate methods, other than a time history approach, used for generating floor response spectra should be submitted for review and approval on a case-by-case basis. The failure of non-seismic Category I components resulting from a seismic event must not cause failure of the main steam piping, main steam drain and bypass lines, or the condenser. d. These components need not be seismically analyzed as described above. BTP 3-1-7 Revision 2 - March 2007 PAPERWORK REDUCTION ACT STATEMENT The information collections contained in the Standard Review Plan are covered by the requirements of 10 CFR Part 50 and 10 CFR Part 52, and were approved by the Office of Management and Budget, approval number 3150-0011 and 3150-0151.
