Abstract: The cables in containment are very important for safety operation and safety shutdown of the nuclear plant. Introduction was made to the main tests process and methods of cables in containment for AP1000 nuclear power plant. This paper discussed some important tests, such as heat ageing test, radiation aging test, DBA test, long-term immersion test etc and analyzed the confronting problem during test process, giving the solutions, which provides references for the cables qualification test in nuclear power plant and the improvement of domestic correlation code standards.
Key words: cables in containment; heat ageing test; radiation ageing test; DBA test; immersion test; special test
