Device is the important equipment for connecting primary Ioops and secondary circuit, and being constituted between one, secondary circuit prevents the second screen that radioactive ray leak
Barrier flows through the primary Ioops coolant of reactor core since coolant damaged may be leaked by irradiation post activation and a small amount of fuel can
With radioactivity, and Secondary Circuit of PWR equipment requirement cannot be by radioactive pollution, therefore inside steam generator
Inverted U-shaped heat-transfer pipe is the core component on reactor pressure boundary, is belonged in nuclear industry non-destructive testing code requirement
Component must be examined.
When carrying out eddy current inspection, needing special inspection locator being installed on tube sheet could realize automatically heat-transfer pipe
Change and check, but locator is likely to occur failure in normal motion sometimes, is fallen from tube sheet so as to cause locator pair
Hydroecium causes to damage.
