Barakah Nuclear Plant Unit 2 ‘almost 60% complete’

Following the successful installation of a 2,000-tonne containment liner plate, construction at Unit 2 of the UAE’s Barakah Nuclear Power Plant has passed the halfway mark

The installation of the 2,000-tonne containment liner plate at Unit 2 of the UAE’s Barakah Nuclear Power Plant took around 15 months to complete.
The installation of the 2,000-tonne containment liner plate at Unit 2 of the UAE’s Barakah Nuclear Power Plant took around 15 months to complete.

Unit 2 of the UAE’s Barakah Nuclear Power Plant (Barakah NPP) is almost 60% complete, according to the Emirates Nuclear Energy Corporation (ENEC).

The news comes following the successful installation of a containment liner plate at Unit 2’s Reactor Containment Building (RCB).

The 15-month job involved the upper dome to be placed, the pressuriser to be lifted into place, and the roof frame for Unit 2’s main control room to be hoisted. More than 240 construction workers were required during the course of installation.

Commenting on progress at Barakah NPP, Mohamed Al Hammadi, CEO of ENEC, said: “Progress of Unit 2 at the Barakah Nuclear Power Plant continues to proceed safely and in adherence to the highest quality standards. Each unit’s progression remains scheduled at approximately 12 months apart. This allows our highly skilled workforce to move efficiently and deliberately through their tasks to ensure the safe and timely delivery of the entire project.

“These milestones for Unit 2 are part of the defence-in-depth safety features in the design. The ongoing collaboration and commitment to safety and quality, seen in all our employees and contractors, is one of the great achievements of our programme. I am pleased with how this progress shows how effectively we are driving the commitments of the UAE peaceful nuclear energy programme through all levels of the organisation,” he added.

Unit 2’s containment liner plate is a cylindrical steel shell that forms part of the inner wall, ceiling, and floor lining of the reinforced concrete RCB. The plate’s structure measures almost 60m in height (77m including the dome) and 45m in diameter. The component had to be constructed in multiple stages and parts, including 19 separate liner rings, each 3m in height.

The containment building and associated liner plate houses the reactor vessel. During the coming months, ENEC’s construction team will cover the plate in concrete to complete the RCB’s structure.

Once completed, Barakah NPP’s four reactors will boast a combined generating capacity of approximately 5,600MW, and will supply nearly 25% of electricity demand in the UAE.

Unit 1 is more than 80% complete, whilst Unit 2 is almost 60% complete, according to ENEC.

The UAE’s peaceful nuclear energy programme is scheduled to complete by 2020, at which point Barakah NPP’s Unit 4 will be connected to the grid.
