As part of FTl's reactor vessel head work it was identified that there was loose boron 1-2" deep 75% around the circumference of the flange. On the other 25% from stud 16 to 30 (clockwise), the boron was hard baked 3-4" thick on southeast quadrant (x-y axis). The large boron accumulation is in the same region as seen in 12RF0, but not as deep.
