I do not know of any manways inside the torus to enter the vent header at BFN. All entries I have seen are through the drywell. The entrances to the vent header at Browns Ferry are in the Drywell and they are about knee high. It has always been a challenge and gets harder as you get older. Not much typically goes on in the vent header. I know of no plans on any enhancements.

There is contingency coatings work in the Torus vent header that may require multiple entries. Question: Has anyone made enhancements in the area of their Torus vent header manways to improve the safety of entries into and out of them??
