ProSIM is a premier global engineering and consultancy partner specializing in end-to-end Nuclear Seismic Qualification. Our core services include Finite Element Analysis (FEA) seismic analysis, structural evaluation, comprehensive piping engineering, Floor Response Spectra (FRS) generation, and life cycle asset management. We provide secure, dependable and code-compliant design support for nuclear Systems, Structures and Components (SSCs) worldwide.

We act as a strategic partner during the competitive bidding process by providing specialized pre-bid engineering insights that mitigate risks and ensure successful seismic qualification. Our detailed engineering deliverables include highly optimized structural configurations, precise sizing calculations, process flow diagrams (PFDs), and custom design macros that streamline procurement and fabrication.

Our engineering team possesses deep competence in global nuclear design standards, including ASME B&PV, IEEE, PNAE and RCC-M/RCC-E. We also strictly adhere to regional and international regulatory frameworks mandated by leading entities such as AERB, NPCIL, BARC and ITER, ensuring your assets clear all safety verifications without costly delays.

We have profound expertise managing and qualifying Class 1, 2 and 3 safety-classified systems across mechanical systems and skids, RCC and structural steel structures, electrical and C&I packages, and special packages such as reactor internals, steam generators and primary piping packages.

Yes. ProSIM delivers exhaustive FEA-based documentation for standalone and skid-based systems. When physical testing is required, we offer end-to-end Shake Table Testing Support, including boundary conditions, specialized testing fixtures and jigs, and thorough qualification test reports to guarantee rigorous regulatory approval.

We provide comprehensive Life Cycle Management solutions including Remaining Life Assessments (RLA), Fitness-for-Service (FFS) evaluations and Plant Life Extension (RLE). Through focused FEA seismic re-evaluations, we modernize legacy SSCs to align with updated safety classifications and evolving regulatory benchmarks.

ProSIM conducts highly advanced Extreme Load Analysis to simulate high-impact scenarios such as Air Shock Waves (ASW) and Air Crash (AC) events. We also perform thorough Seismic Margin Assessments (SMA) to determine the failure probabilities of components during extreme seismic activity.

Our scope includes 2D and 3D piping layout optimization, pipe stress and flexibility analysis (static and dynamic), and critical hydraulic design. We also handle strict P&ID reviews, Material Take-Off (MTO) preparation and Bill of Quantities (BoQ) extraction to ensure accurate, cost-effective procurement.

We use a highly refined Project Management Practice (PMP) that integrates with rigorous nuclear Quality Management Systems (QMS). We also apply our proprietary ecosystem of validated IP — SOPs, validation checklists and in-house automation macros — to minimize human error, boost productivity and identify anomalies at the earliest project stages.

Our clients include private and state-owned Nuclear Power Plant Operators, global EPC contractors, Tier-1/2/3 equipment manufacturers, system integrators and regulatory bodies. If you require rigorous FEA seismic qualification data, strategic pre-bid support or robust certification services, our team is ready to collaborate.
