Concrete works of the turbine hall foundation slab at Unit – 2 of Bangladesh’s maiden Rooppur Nuclear Power Plant (RNPP) has been completed on August 6, 2019. The structure required 3,782 tons of rebars and 23,550 cubic meters of concrete. According to Sergey Lastochkin, Vice-President of the Rooppur NPP construction Project, this is an important stage of construction that will be followed by the erection of walls of the turbine hall. Necessary preparation has begun for the next stage job.
Turbine hall houses steam generators and the turbine. Heat is removed from the reactor core by coolant; it may be a liquid or gaseous substance which passes through the core. This thermal energy is used to produce water steam in the steam generator. Steam’s mechanical energy is supplied to the turbine generator where it goes into electricity and further moves to users by wires. The Rooppur NPP will have two units, each with a Generation 3+ Russian VVER-1200 reactor, with active and passive safety systems. Construction works of the project are progressing, according to the schedule. The first unit is scheduled to be commissioned in 2023 and the second in the following year. Engineering division of Rosatom State Atomic Energy Corporation of Russia is the general contractor.
