en.Wedoany.com Reported - Recently, the first batch of electrical penetration assemblies for Unit 1 of the Xudapu Nuclear Power Plant arrived smoothly at the Xudapu nuclear power project site.

Electrical penetration assemblies are installed on the containment of a nuclear power plant to achieve electrical connections between the inside and outside of the containment. They maintain the integrity of the reactor containment and electrical continuity during plant operation, serving as a fundamental guarantee for the safe operation of the reactor.

To facilitate equipment delivery, Liaoning Nuclear Power organized multiple special meetings with personnel from the general contractor, CNNC Engineering's Procurement Center, and the design institute. These meetings clarified the qualification test plan, reasonably formulated a special plan for prototype qualification and engineering manufacturing, and arranged for personnel to be stationed at the factory. A daily reporting tracking mechanism was established to monitor the entire chain of equipment testing and production. By strengthening process control, the connection time between various stages was effectively shortened, with the qualification test cycle lasting 8 months. The prototype completed all qualification tests in May 2026, and the first batch of electrical penetration assemblies passed factory acceptance in June 2026.

The arrival of the first batch of electrical penetration assemblies for Unit 1 of the Xudapu Nuclear Power Plant marks a substantive step forward in the material preparation for the nuclear island installation works of this unit, providing a prerequisite for the full-scale commencement of subsequent installation activities.
