ProSIM Completes the Seismic Evaluation of Fire Fighting System for Kakrapara Atomic Power Plant (KAPP) of Nuclear Power Plant Corporation (NPCIL)
ProSIM has successfully completed the seismic evaluation of the firefighting system attached to the reactor auxiliary building of KAPP site. Work involved the design of routing, optimisation of pipelines, design and evaluation of supports and anchor bolts, pipe stress/ flexibility analysis using finite element analysis (FEA) structural integrity assessment. Seismic evaluation was conducted for both SSE and OBE seismic loads, as per ASME B&PV Section III, subsections D and NF. Seismic anchor movement (SAM) was calculated at all anchor locations, as the complex pipeline circuit spanned across different elevations. Considering the utilisation of anchor bolts, bolt sizes and anchor plates were optimised.
