sis is performed, the "rigid body" impact loads will be applied; however, the masses of the impacted structures will be adjusted by adding on the hydrodynamic masses of impact. The numerical values of hydrodynamic masses will be obtained from the appropriate correlations for cylindrical and flat structures in Figure 6-8 of NEDE-13426P. NOTE 4: Steam Condensation and Chugging Loads Single-Vent Lateral Loads The following dynamic single-vent load specification will be used: A tip lateral force given by: F(t) = A(τ)sin(πt/τ) 0$t#τ 6.2.1.1.C-26 Revision 7 - March 2007 where A(τ) = (50 - 20τ/3)klbf for 3 ms # τ # 6 ms shall be applied to each downcomer with τ varied between 3 and 6 ms as indicated. In addition, a separate assessment shall be made for a load with a tip lateral force of for each downcomer.
