Specialists of subcontracting companies Trest RosSEM, LLC Roin World and JSC Energospetsmontazh have performed a scope of works related to installation of two beams of the polar crane on the rail track at Rooppur NPP Unit 1 in Bangladesh. hese are basic steel structures of the crane, by means of which further transportation and installation operations for main process equipment of the containment (reactor pressure vessel, steam generators, pressurizer) will be performed. The polar crane beams were installed using a heavy tracked crane Liebherr in the reactor pressure vessel at elevation +38,500 m.
Currently, works related to installation of the crane structures and mechanisms on the crane track are under way.
Due to the crane moving on a circular track, it will be capable of performing all handling works at any point of the reactor compartment.
It is planned to complete the works on the polar crane installation this June, which will be followed by installation of oversized and heavy equipment of the reactor plant of the first NPP unit.
After the NPP commissioning, the crane will be used for repair works and fuel transportation.
