The UAE's Barakah nuclear power plant has achieved another key milestone with testing set to get under way on the second unit of the facility. The Emirates Nuclear Energy Corporation (Enec) announced on Tuesday that fuel assembly had been completed on Unit 2 of the four-reactor plant in Abu Dhabi. Testing will now begin ahead of the reactor being fired up. In August, the UAE became the first Arab country to produce nuclear energy after Unit 1 became operational. The unit was fully operational by December and is capable of generating 1400 megawatts of electricity for the nation's grid. Once Barakah's four reactors are online, the plant will deliver clean, efficient and reliable electricity for decades, providing about a quarter of the country’s electricity and eliminating up to 21 million tonnes of carbon emissions annually. That is comparable to taking 3.2 million cars off the roads each year. Barakah, in Al Dhafra, is the cornerstone of the UAE's peaceful nuclear energy programme. Construction began in 2012 and it was built in partnership with the Korea Electric Power Corporation. Last year it was revealed that construction of Units 3 and 4 was in its final stages – 93 per cent and 87 per cent complete respectively – benefiting from lessons learnt during the construction of Units 1 and 2. The Barakah complex as a whole is now more than 95 per cent complete.
