Large cubic content of

concrete grouting


The concrete grouting for Taishan 1# NI raft foundation lasts 86 hours, and 9300m³ concrete is poured, which create a record of the largest cubic content of NPP concrete grouting in once around the world. No obvious crack occurred in the concrete structure of the raft foundation which was grouted in one time.

Containment shell slip-form construction with hydraulic lifting devices

The system of “slip-form construction with hydraulic lifting devices” settle a difficult problem during double-wall containment construction. This formwork system with advanced technology and high grade of automatic mechanization, reduces the labor hardness, and at the same time, ensures the construction quality of containment cylindrical.

10


Construction technology research and application ：In the field of NPP pool construction around the world,

3D of IRWST pool adopts the technology of welding without backing, with all the welds passed the 100% radiographic test (RT).

11


Construction technology research and application ：Special technology systems and intellectual property

rights in Nuclear power construction field come into being; 298 items of patent and 31 items of software copyright are awarded, with several items of construction technologies kept ahead of the world.

Ⅲ Project Management Experience

Nuclear safety culture system

One principle: Prevent Problems, Work Properly, Do It Right the

First Time, Keep Improving

Two “first” : Safety First, Quality First

Three “Serious”: Serious Plan before the Event, Serious

Implement during the Event and Serious Inspection after the Event

Four “all things”: All things have rules to follow, all things

have someone to take charge, all things have someone to inspect

and all things are well documented

Systematic nuclear safety culture system has been formed through nuclear power construction of 30 years
