Polar crane beams set up at RNPP

Two polar crane beams have been installed at
the first power unit of Rooppur Nuclear Power Plant (RNPP) in Pabna,
according to a message received here today.

It said the beams of the polar crane were installed in the reactor building
using a Liebherr heavy crawler crane, at an elevation of +38.500 m.

These are the main metal structures of the crane, with the help of which
the operations for the transportation and installation of the main
technological equipment of the containment area (reactor vessel, steam
generators, pressure compensator) will subsequently be carried out.

“Installation of heavy structures required complex and well-coordinated
work of subcontractors. Specialists of Roin World LLC provided the
preparation of access road for lifting the beams by the crane, specialists of
Trust RosSEM completed installation of containment lobes for installation of
rail track at 38,500m in the shortest possible time, specialists of
Energospecmontazh JSC carried out the final operation- installation of beams
on the rail ways”, said deputy director for project management of branch of
ASE JSC in Bangladesh-chief project engineer Yuri Koshelev.

Currently, work is underway to install structures and crane mechanisms on
crane runways.

Due to movement of crane along a circular path, it will be able to perform
all loading and unloading operations at any point in the reactor compartment.

The RNPP with two VVER-1200 reactors with a total capacity of 2,400 MW is
being built according to a Russian project 160 km from the capital of
Bangladesh, Dhaka, in accordance with the general contract dated December 25,
2015. The general contractor for the construction of the Rooppur NPP is
Atomstroyexport (Engineering Division of Rosatom).

Russian state owned company-Rosatom- is carrying out construction of the
RNPP in Bangladesh.
