ENEC installs containment liner plate for UAE's first nuclear energy plant
Construction of Barakah Unit 1 progressing on schedule; safety, quality and security remain paramount to UAE's nuclear energy program
The Emirates Nuclear Energy Corporation (ENEC) and the Korea Electric Power Corporation (KEPCO) installed the first modularized sections of the 2000 ton steel cylinder. The installation was the culmination of months of work, and is just one element of the complex construction program underway at Barakah.
With the CLP installation proceeding, ENEC and KEPCO remain on track to deliver the country's first nuclear energy reactor, Barakah Unit 1, in 2017. A total of four nuclear energy reactors are set to be constructed by 2020, producing a significant portion of the UAE's energy needs and saving up to 12 million tons in carbon emissions every year.
The Containment Liner Plate is a cylindrical steel shell that forms the inner wall, ceiling, and floor of the Reactor Containment Building (RCB)
Due to the magnitude of the Liner Plate, the component has to be constructed in multiple stages and parts. A total of 19 separate liner rings make up the structure, each measuring 45meters in diameter, and 3 meters in height. The floor and the first two levels of the Liner Plate were made off site and have been installed over the past two months in-situ. The next three levels of the liner have been fabricated and welded together on site, and then crane-lifted and installed last week weighing almost 200 ton. Over the next 10 months, the team will continue to fabricate and install the remaining 14 sections of the CLP.
A special Very Heavy Lift (VHL) crane, with a total lifting capacity of 1,600 tons, was shipped to the UAE to carry out the installation process. The Terrex Crawler Crane took just under two hours to lift and swing the Liner Plate safely into position.
Prior to the installation, the site team carried out a series of ground condition tests to ensure the safest possible conditions for the lift. Multiple load tests were also carried out on the crane. Two simulations tested both the lift load of the crane, and the actual lift and swing of the structure following the same radius as the Liner would follow, from its original location to its installation in the containment building. In addition, wind speed conditions were carefully monitored throughout the entire process.
ENEC is working to deliver safe, clean, reliable and efficient nuclear energy to the UAE. By 2020, ENEC aims to have four APR-1400 reactors providing clean electricity to meet the nation's growing energy needs.
In July 2012, ENEC commenced construction on Unit 1 following the receipt of the Construction License from the Federal Authority of Nuclear Regulation (FANR) and a No Objection Certificate from Abu Dhabi's environmental regulator, the Environment Agency - Abu Dhabi (EAD). Construction of Barakah Unit 1 will take five years, with the plant expected to become operational in 2017 (subject to further regulatory review).
Since July, ENEC has poured more than 20000 cubic yards of concrete to form the foundation slab of the Barakah Unit 1 Reactor Containment Building, which will ultimately house the nuclear reactor. ENEC has also poured safety concrete for the auxiliary building, turbine building and cooling water structures.
ENEC has selected KEPCO's APR1400, a Generation III+, 1400 Megawatt nuclear energy plant - proven technology that meets the highest international standards for safety and performance. The plants are designed to withstand extreme events including tsunami, earthquake and station black-out.
ENEC will apply for an Operating License for Unit 1 in 2015 and will pour concrete for Unit 2 in 2013. ENEC is building a total of four Units at the Barakah site. The first Unit will be operational in 2017, with one additional Unit becoming operational each year up to 2020.
