Advanced Test Reactor High-Temperature Loop Inpile Tube and Large Inpile Tube Expansion Joint Gland Seal Design Modification

The Advanced Test Reactor (ATR) high-temperature loop inpile tube and large inpile tube (including crossarm) bellows expansion seals have several design and fabrication issues. Additionally, these seals are very difficult to install and upon removal, the bellows are destroyed. The purpose of this work is to design, test, and fabricate expansion joint gland seals to replace the ATR high-temperature loop inpile tube and large inpile tube (including crossarm) bellows expansion seals. The issues associated with the bellows expansion seals discussed above can be eliminated by switching to the expansion joint gland seals.
