// SECTOR S-01 — NUCLEAR STRUCTURES

Structural engineering design for nuclear power plants.

Since 2021 WVA has qualified piping, cable-tray and HVAC supports and designed embedded parts for two NPCIL 700 MWe stations, working with Tata Consulting Engineers. Our support-qualification team averages 500+ supports a month, with over 95% accepted at first review — reports issued in NPCIL format, ready for AERB review cycles.

// HOW WE WORK ON NUCLEAR

Rigour a reviewer can audit.

QUALITY SYSTEM ISO 9001:2015, scoped to nuclear Certified for structural engineering design of nuclear power plants. Every calculation is checked, signed and issued under controlled document review.
SEISMIC Floor response spectra and qualification FRS generated from building models at anchor elevations (OBE/SSE, specified damping); response-spectrum and time-history analysis to plant inputs.
CODES AERB, ASME III and IS AERB/SS/CSE-1 (concrete), CSE-2 (steel) and CSE-4 (embedded parts) · ASME BPVC Section III, Subsection NF · ACI 349 · ASCE 4 · IS 456, 800, 875, 1893, 13920.
TOOLS STAAD Pro, ETABS, MIDAS, RCDC, IDEA StatiCa Backed by our own in-house, validated design software.
DELIVERABLES In the reviewer’s format Design basis report, analysis report, signed calculation sheets, support and EP design reports, native STAAD files and comment-resolution notes for AERB/NPCIL/EPC reviewers.

// WORKFLOW — TWO PHASES

From tender to final design.

Automation where it saves time, engineering judgement where safety class demands it.

Tendering PHASE 1 · SPEED

Tender specs received Drawings and scope
Automated STAAD modeller Geometry and approximate loads
Skeleton STAAD analysis Simplified model for sizing
Automated BOQ extraction Steel tonnage plus connection allowance

Detailed engineering PHASE 2 · PRECISION

Safety-class check Safety-related → AERB · non-safety → IS
Code basis AERB/SS/CSE-1 & 2 with SSE, pressure, thermal loads — or IS 456, 800, 1893
Analysis and design checks In-house AERB design modules / limit state
Automated section optimiser Resize until utilisation is optimal
Final design results Members and reinforcement

ENGAGEMENT

Fixed-scope packages Pipe supports, equipment foundations, RCC pedestals

Man-month / rate contract Long-duration nuclear engineering support

Independent design review Second check for EPCs

NEXT · SMRs & INTERNATIONAL PARTNERS As India builds Small Modular Reactors and opens nuclear to foreign technology partners, WVA offers an AERB-fluent local team to adapt designs to Indian sites, materials and codes — without compromising the original design intent.
