en.Wedoany.com Reported - Unit 1 of the Rooppur Nuclear Power Plant recently completed the boric acid flushing of the reactor primary circuit pipelines, setting a record for the shortest duration of this procedure at 81 hours. This work is a crucial preparatory step before the physical start-up of the unit, marking the project's transition from the preliminary preparation phase to the physical start-up phase.

The boric acid flushing operation was completed through the collaborative efforts of participating project experts, facilitated by efficient production organization and management. As a critical technical step before physical start-up, this work lays the foundation for loading nuclear fuel into the reactor core. Previously, Unit 1 had undergone a series of preparatory activities, including comprehensive equipment inspections, disassembly and testing of key process nodes, monitoring of the metal condition of the reactor pressure vessel and pipelines, safety system tests, as well as the removal of simulated fuel assemblies, diagnostics of in-core components, and monitoring systems.

Following the completion of the aforementioned work, the unit is now fully prepared for the next phase of physical start-up. The successful completion of the boric acid flushing ensures that the reactor primary circuit system meets cleanliness standards, fulfilling the requirements for subsequent fuel loading and start-up.
