Outer containment concreting ends in RNPP Unit 1

With the accomplishment of concreting of the dome part of the outer containment, the entire concreting of the outer containment of the reactor building of Unit 1 at Rooppur nuclear power plant (NPP) has been completed 45 days ahead of schedule.

According to Rosatom, the Russian contractor of the project, the entire process took 110 days instead of 155 and was scheduled for April 15, 2023.

Some 1,383 cubic meters of concrete were used for the dome part concreting. Some 65 experts including 44 Bangladeshis took part in the process.

Owing to the optimisation of the outside containment concreting period, it became possible to install the inner and outer parts of steel structures of the passive heat removal system (PHRS) deflector in the design position ahead of schedule. The complex operation was performed in two stages.
