Wedoany.com Report-Oct 09, China National Nuclear Corporation (CNNC) said the generator stator has been installed at the ACP-100 small modular reactor (SMR) demonstration project at the Changjiang NPP in Hainan Province. The multi-purpose 125 MWe SMR (also known as Linglong One) is a pressurised water reactor designed for electricity generation, urban heating, urban cooling, industrial steam production, or seawater desalination.
The ACP-100 generator consists of a stator, rotor, cooler, and two bearing blocks. The 130-tonne generator stator, which is about 6 metres long, has been installed on the base of the generator. CNNC said the main complexity of the lift operation was the small area of the site.
“The generator stator had to be raised with two cranes, carried through the maintenance hole to the steam turbine platform and, finally, installed on the base of the generator, which required extremely high positioning accuracy,” CNNC noted. Installation of the generator stator paves the way for the subsequent installation of the steam turbine generator block.
