Structural Calculations Clause Samples

Structural Calculations. Based on a sampling review of the calculations and design documents, the NRR staff noted that, with the exception of the calculations for the Control Rod Drive Missile Shield, the licensee’s calculation methodology and assumptions appear to be reasonable and consistent with the original design and licensing basis code requirements, During the January 2002, audit, the NRR staff found that the analysis of the Units 1 and 2, fan-accumulator room walls, used a computer program, SOLVIA, that has not been reviewed by the NRR staff in other applications. By letter dated May 31, 2002, the NRR staff requested that the licensee provide detailed documentation for the validation of the use of the SOLVIA code. The licensee responded to the RAI by latter dated July 12, 2002. In the response licensee stated that the SOLVIA program is a commercially-available finite element analysis software program for linear and nonlinear analysis of displacements, stresses, and temperatures under static or dynamic conditions. The program can be used to perform various analyses, including: – Complex structural analyses, including elastic and plastic response, concrete cracking, inclusion of rebar in beam and shell elements. – Vibration analyses for frequencies and mode shapes, general forcing functions, harmonic response, power flow with viscous or hysteretic damping. – Earthquake analyses using response spectrum method, weighted damping, raw/design/envelope response spectra, and time integration of nonlinear response. – Buckling and post-buckling analyses, including automatic load stepping, initial imperfections, and linearized buckling. – Heat transfer analyses, including three dimensional conduction with convection/radiation surfaces in stationary/transient analyses. As part of the SOLVIA validation, the NRR staff requested bench marking data to provide a comparison with a program which has been approved by the NRC staff. The licensee selected the ADINA computer program for comparison with the SOLVIA program. Similar to SOLVIA, ▇▇▇▇▇ provides a single-system program for comprehensive finite element analyses of structures, fluids, and fluid flows with structural interactions. The following documents indicate that the NRC has found the ADINA program to be acceptable: – NUREG/CR-6651, "International Comparative Assessment Study of Pressurized Thermal Shock in Reactor Vessels," by Oak Ridge National Laboratory. – Appendix A in the NRC SER for Amendment No. 48 to the LaSalle County Statio...
