PROSIM BAGS ORDER FOR GENERATION OF FLOOR RESPONSE SPECTRA (FRS) FOR SWITCHYARD & ELECTRICAL BOP PACKAGE FOR KUDANKULUM NUCLEAR POWER PROJECT –(KKNPP) OF NUCLEAR POWER PLANT CORPORATION (NPCIL)
ProSIM has bagged an order for generation of floor response spectra (FRS) for four buildings and four frame structures of KKNPP site. Each of the flour buildings have 4 different elevations at which various electrical equipment are mounted. FRS is required for seismic qualification of all electrical equipment mounted at different elevations in the switchyard. Time history analysis of the RCC building and steel frame structures will be carried out considering the synthetic time history curve provided by the end user. Finite element analysis (FEA) based tools will be used for this purpose as specified by the NPP operator, viz, NPCIL. Generation of floor response spectra (FRS) will be done as per guidelines of AERB/SG/D-23 and USNRC regulatory guide 1.122.
