MEIL Group has completed one of the largest monolithic concrete pours in NPCIL’s Pressurised Heavy Water Reactor (PHWR) programme at the Kaiga Units 5 & 6 Nuclear Power Project, Karnataka. The continuous operation involved placement of about 7,250 m³ of concrete with a rebar density of 360 kg/m³, marking a major construction milestone for Kaiga Units 5 & 6.
The pour required extensive mobilisation of materials, plant and manpower to maintain uninterrupted quality and schedule. MEIL established a temperature-controlled concrete production capacity of 360 m³/hr and deployed concrete pumps with a capacity of 340 m³/hr to maintain a placement temperature of 19°C. To support mix cooling and thermal control, MEIL Group set up a 510 TPD ice production capacity with 400 MT of ice storage, and provided 2,600 MT of combined cement and flyash storage. All concrete ingredients were made 100% available before the start of the pour, enabling continuous operations despite the scale and complexity of the task.
Working under a remote site environment with heavy monsoon rainfall and constrained access, MEIL designed and erected a 75-metre-diameter rain protection system to enable continuous placement while safeguarding material quality, worker safety and productivity. The operation demanded precise coordination across batching, transportation, placement, compaction, testing and curing; MEIL Group implemented comprehensive Quality Assurance and Quality Control (QA/QC) measures at every stage to comply with the stringent standards governing nuclear construction.
A large, multi-shift workforce of engineers, supervisors, quality professionals, surveyors, technicians, operators, safety personnel and skilled workmen executed the pour with rigorous safety protocols and continuous testing to ensure structural integrity and long-term performance.
This historic concrete pour at Kaiga Units 5 & 6 demonstrates MEIL Group’s engineering capability, detailed planning and execution excellence in one of the most demanding sectors of infrastructure construction. As India advances its indigenous nuclear power programme, this achievement highlights MEIL Group’s technical and logistical strengths and positions the company for future strategic assignments in nuclear and critical-infrastructure sectors.
