Embedment of Temporary Tower Supports
_
The licensee changed the sequence of operations in the construction of
-
the containment building.
This resulted in the placement of the fuel
!
pool vall.corerete without removing the temporary polar crane supports, I
two of which were found embedded to a height of 65 ft. in the permanent fuel peel concrete. This embedment included the 6-ft. square columns,
'
together with steel braces and steel plates 6 ft x 4-1/2 ft x l-1/2 in.
thickness.
At the time of the inspection a program of removing protruding steel and refinishing the concrete was in progress.
The work of c= bedding the temporary polar crane supports had been perforced -
without documented evidence of detailed drawings, calculatior.s or procedures.
Undocumented codifications, including rebar cutting, were also made on adjacent columns to accom=odate braces and cables.
This item is unre-solved.

January 11, 1972 which showed 27-in. dia=eter vent holes in the box i
girders, in addition to 18 in. x 36 in. openings in each partition l

documentation included Babcock & Wilecx Topical Report No. 1402 and a June 7, 1973 Babcock & Wilcox letter to the licensee referencing
"Three Mile Island 2 resolution of Weld Filler Material, B&W, NSS-6."
This iten is resolved.
