Hydraulic pressure test of containment penetration protection sleeves for Haiyang Nuclear Power Unit 3 in China succeeds on first attempt
Recently, the hydraulic pressure test of the containment penetration protection sleeves for the main steam and main feedwater pipelines of Haiyang Nuclear Power Unit 3 of State Power Investment Corporation (SPIC) Shandong Nuclear Power was completed, with all four sleeves passing the test on the first attempt. The protection sleeves are an important part of the containment pressure boundary and can safeguard the bellows expansion joints under abnormal pipeline conditions. It is understood that this test was relatively difficult. The sleeves had long been embedded in the containment, the original pipelines could not be damaged, and the on-site space was narrow, making it impossible to install the tooling. To address these challenges, the production preparation project team innovatively adopted the process of "removing the original guard plate + welding flanges to build a pressure chamber," and joined forces with the design institute and equipment manufacturer to form a special team, conducting multiple simulation verifications and reviewing...

Mobilization Meeting for High-Quality Fuel Loading of Haiyang Nuclear Power Unit 3 Convened
On September 1, Shandong Nuclear Power organized a themed joint Party building learning session and the mobilization meeting for high-quality fuel loading of Haiyang Nuclear Power Unit 3. Centering on the goal of high-quality fuel loading for Unit 3, the meeting further unified understanding, clarified responsibilities, and promoted the safe, orderly, and high-quality implementation of fuel loading preparations, laying the foundation for the subsequent commissioning of the Phase II project of Haiyang Nuclear Power. The meeting conducted a themed joint Party building learning session. The Haiyang Project Department of Shanghai Nuclear Engineering Research and Design Institute (SNERDI), the Commissioning Center of SNERDI, China Nuclear Industry Fifth Construction Co., Ltd., and Jiangsu Electric Power Construction No. 3 Engineering Company respectively reported on the fuel loading preparation status of Unit 3. Participants discussed topics including Party building leading project breakthroughs and ensuring high-quality fuel loading of Unit 3. The meeting also commended...

SPIC Haiyang Nuclear Power Unit 3 Hot Functional Test Successfully Completed
At 17:30 on August 13, the hot functional test (HFT) of Unit 3 at SPIC Shandong Nuclear Power Haiyang Nuclear Power Plant was successfully completed, laying a solid foundation for subsequent fuel loading and first grid connection of the unit. ▲Aerial view of Shandong Nuclear Power Haiyang Nuclear Power Plant. The hot functional test is the most critical non-nuclear comprehensive verification phase before nuclear fuel loading, often referred to as the "final exam" or "mock exam" before a nuclear power plant officially generates electricity. By executing a series of tests simulating actual operating conditions within the pressure and temperature ranges of normal reactor operation, it comprehensively verifies the reliability of nuclear island and conventional island systems and equipment under hot operating conditions, ensuring that relevant parameters meet design requirements. ▲On July 4, during the normal residual heat removal system (RNS) test at the heat-up platform of the hot functional test...
