ENEC Installs Barakah 3 Nuclear Reactor Vessel Head

Barakah nuclear project

The Emirates Nuclear Energy Corp. (ENEC) completed the installation of the Unit 3 reactor vessel at the Barakah nuclear site in the United Arab Emirates.

The RV weighs over 400 tonnes and measures almost 15 metres in height and it will contain the controlled nuclear reaction. It is one of the many defense-in-depth barriers at the nuclear plant. The Unit 2 RV was installed in 2015 and the Unit 1 RV was installed in 2014.

Reactor vessels consists of a reactor vessel body and reactor vessel head. The body is the largest component and is designed to contain the fuel assembly, coolant and fittings to support coolant flow and support structures. The head is attached to the top of the reactor vessel body and contains penetrations, which are driving mechanisms that allow the control rods to lower into the vessel and attach to the fuel assembly, controlling or stopping the nuclear reaction when necessary.

Overall, construction of units 1-4 is more than 65 percent complete. All four Korean-designed reactors are expected to be online by 2020.
