The 5,000-tonne capacity Sarens SGC-250, otherwise known as Big Carl, has lifted transfer compartment pool (TCP) into the Unit 2 reactor building.
The prefabricated TCP weighs approximately 1,200 tonnes. It was lowered onto a set of jacks and props that will support the structure while it is 鈥榮titched鈥 into position within the building
The transfer compartment pool will be used for the safe handling and rotation of nuclear fuel assemblies into and out of the reactor building. The system keeps spent assemblies immersed in purified, borated water to ensure heat is removed from fuel and cooled to the right temperature. This ensures that the fuel is managed safely and people working in the vicinity are protected.
The main contractor, Bylor Joint Venture, said that the TCP lift marked the culmination of two years鈥 work across a range of Bylor teams and required close collaboration with the client and joint design office (JDO) teams.
In a social media post, Bylor said: 鈥淎 huge amount of learning from Unit 1 has been applied to the assembly and construction of the TCP in Unit 2 reactor building by the Bylor teams to identify opportunities to carry out additional works in the bunker across both the pools and precast scopes 鈥 reducing the work in Nuclear Island and improving the control of the environment in which the mechanical scope works are carried out.鈥
