informatifon, dated December 29, 1975. Our post occurrence review I
of the facility drawings and the procedure utilized to conduct pre-
[
operational testing of this' drain pipe, revealed that a procedure deficiency existed. This procedure required the drain pipe be cut
)
for system flushing; however, the procedure did not include provisions for restoration following. completion of the flushing operation.
