[UPDATED] The Emirates Nuclear Energy Corporation (ENEC) said Sunday that Cold Hydrostatic Testing (CHT) had been completed for Unit 3 of the Barakah Nuclear Energy Plant in Abu Dhabi, UAE.
The testing is considered a crucial step forward towards the completion of Unit 3 of the 4-unit Barakah plant. ENEC noted that current operations incorporate the lessons learned from development of Units 1 and 2 at the plant.
Prior to the commencement of CHT, Unit 3’s Nuclear Steam Supply Systems were flushed with demineralized water, and the Reactor Pressure Vessel Head and Reactor Coolant Pump Seals were installed. During the Cold Hydrostatic Testing, the welds, joints, pipes and components of the reactor coolant system and associated high-pressure systems were verified.
As a part of CHT, the pressure inside Unit 3’s systems was increased to 25 percent above what will be the normal operating pressure, demonstrating the quality and robust nature of the Unit’s construction.
Throughout the testing process, inspection teams from Korea Hydro and Nuclear Power (KHNP), the Korea Electric Power Corporation (KEPCO), along with ENEC and Nawah Energy Company (Nawah) commissioning oversight and quality surveillance personnel, performed detailed system inspections, verifying no component and piping system leakage.
Earlier this year, ENEC and KEPCO successfully completed all major construction work including major concrete pouring, installation of the Turbine Generator, and the internal components of the Reactor Pressure Vessel (RPV) of Unit 3, which paved the way for the commencement of testing and commissioning.
The project at Barakah is progressing steadily and as of the end of October 2018, Unit 3 was more than 86 percent, while overall progress rate of Units 1 to 4 is more than 91 percent complete.
