Overall Containment Tightness and Strength Test Successfully Completed for Unit 3 of China's Liaoning Xudapu Nuclear Power Plant

en.Wedoany.com Reported - On April 3rd, the overall containment tightness and strength test for Unit 3 of China's Liaoning Xudapu Nuclear Power Plant was successfully completed.

The containment is the core barrier of the nuclear power plant's defense-in-depth system. This test was a crucial "admission exam" before the unit's commercial operation. The entire test strictly followed nuclear safety regulations and design standards. By simulating the pressure environment of a design-basis accident, it comprehensively verified the containment's integrity, leakage rate, and the sealing performance of key components, confirming the project's quality and the effectiveness of safety controls.

To ensure the smooth progress of the test, Liaoning Nuclear Power, in collaboration with all participating construction units, formed a dedicated攻坚 team. Before the test, prerequisite checks, risk analysis, and multiple rounds of simulation exercises were completed. During the test, professional teams worked in 24-hour shifts, strictly controlling the pressure increase rate. Precise pressure holding, data collection, and comprehensive inspections were conducted at each pressure plateau, safeguarding every safety checkpoint.

The successful completion of this test marks the official entry of Unit 3 of the Xudapu Nuclear Power Plant into the final冲刺 stage before commissioning and power generation, laying a solid foundation for the orderly advancement of subsequent work.
