A second unit at Barakah Nuclear Power plant has begun commercial operations, the country's nuclear regulator said. In an online briefing, Christer Viktorsson, director general of the Federal Authority for Nuclear Regulation (FANR), said the second reactor was now producing energy for commercial purposes. He further said review of the requirements needed for the third unit's operating licence has begun. Mr Viktorsson said FANR conducted more than 40 inspections covering nuclear safety, nuclear security and non-proliferation at Barakah in 2021 to ensure that it meets regulatory requirements. The second unit was <a href="https://www.thenationalnews.com/uae/2021/09/14/uaes-second-nuclear-power-plant-unit-successfully-connects-to-grid/" target="_blank">connected to the national power grid</a> in September 2021. Barakah will provide 25 per cent of the country's energy needs once all four units are running. The production of clean nuclear energy will reduce reliance on fossil fuels and gas-fired power stations, which currently provide the UAE with more than 90 per cent of its energy. Speaking last month, Mohamed Al Hammadi, managing director and chief executive of Emirates Nuclear Energy Corporation said the plant is a "sustainable powerhouse... spearheading the nation’s commitment to tackling climate change". "Since the start of commercial operations in 2021, unit one has been the largest single electricity generator in the Arab world, completely carbon emissions free," he said at Abu Dhabi Sustainability Week. Barakah's production of nuclear energy for homes and businesses means 22.4 million fewer tonnes of carbon are released into the environment. That is the equivalent to the carbon generated by 4.8 million passenger cars driven for one year. There about 3.5 million cars on the UAE’s roads today. Data from the Emirates Water and Electricity Company (EWEC) shows carbon emissions are expected to decrease by 50 per cent in 2025, when Barakah is fully operational, as well as the launch of additional large scale solar power generation and efficient water desalination, state news agency Wam said in January. The Barakah Plant is one of the largest nuclear energy plants in the world, with four APR-1400 units. Construction of the Plant began in 2012.
