Enclosure In the past there has been some concern shown by the project for the IHTS tee which connects the SWRS rupture discs and associated systems to the IHTS evaporator inlets. The concern in question was the possibility that in the course of a large or intermediate sodium-water reaction a " standing reaction front" might develop at the junction of the tee for a period of time sufficient to overtemperature the tee.

This situation has been logically named the " hot tee" problem.

Please provide the current status on the " hot tee" problem.

If the project no longer considers it a problem, please provide the analysis upon which that conclusion is based.
