Engineering heavy-lift solutions for the controlled rotation and installation of generator stators weighing up to 350 tonnes as part of Ukraine's nuclear power plant modernization programmes.
Modernisation of nuclear power plants often requires the replacement or refurbishment of generator stators weighing more than 300 tonnes. These components must be rotated, transported and positioned within existing turbine halls where space is limited, structural tolerances are tight and safety requirements are among the most demanding in the engineering industry.
Phenyx Rebuild developed a comprehensive heavy-lift engineering methodology to support this type of operation, providing the technical basis required for safe execution while complying with the stringent standards applied to nuclear facilities.
The engineering package defined the complete lifting concept, including the hydraulic gantry configuration, load distribution strategy, temporary support systems and equipment arrangement required for controlled stator rotation. The methodology incorporated structural load assessments, ground bearing pressure analysis, risk evaluation, temporary works design and lifting sequence development. Engineering was performed in accordance with applicable international standards and recognised heavy-lift practices, while integrating nuclear safety principles, including the ALARA philosophy for work in controlled environments. The result was a practical engineering framework that supports safe planning and execution of complex heavy-lift operations during nuclear power plant modernization.
Developed a complete heavy-lift engineering methodology for the controlled handling and rotation of a 330–350-tonne generator stator, applying international engineering standards and nuclear safety principles.
Engineered and executed the final 330-metre skidding of the 36,200-tonne New Safe Confinement using a bespoke 116-shoe hydraulic skidding system, safely positioning the world's largest land-based movable structure over Reactor No. 4 at Chernobyl.
