Cold hydrostatic testing (CHT) on Unit 1 at the 5,600-MW Barakah nuclear project in the United Arab Emirates (UAE) was completed, a crucial step in preparing the plant for commercial operations.
The CHT verifies that welds, joints, pipes and components of the reactor coolant system and associated high-pressure systems meet quality standards, per regulations of the Federal Authority for Nuclear Regulation. During the testing, previously processed water filled the primary circuit and was circulated by the reactor coolant pumps, which help maintain a safe temperature inside the reactor during operations. The testing follows completion of a number of milestones, including energizing the switchyard for units 1 and 2.
Construction of all four units is more than 58 percent complete. Unit 1 is more than 84 percent complete and Unit 2 is 64 percent complete.
