Subject: Powernet: Bubble Hoods and Breathing Air Supply
Sent by: [email protected]
Palo Verde currently uses the LANCS Air Fed (Bubble) Hood for making internal Steam Generator entries. Until recently, we used the plant’s service air system to supply breathing air; however, due to a plant modification this was no longer available for use and we have subsequently replaced the plant system with temporary breathing air compressors that are external to the Containment Building.
Palo Verde would like to know the following:
If you use bubble hoods, what brand / manufacture do you use?
What is your source for grade D breathing air, e.g., plant system, compressor, etc.?
Thanks in advance, Seth
