摘要：
In a steam generator for a pressurized water type nuclear reactor, for the purpose of isolating a water chamber in the steam generator from a coolant piping communicating with the water chamber, a plug is disposed in a nozzle section of the coolant piping, the plug is supported by a support arm having an angle adjusting screw and fixedly secured to a mount seat at a manhole communicating with the water chamber, and preferably, a cover is provided on the mount seat at the manhole.
