Exchange of SGs - radiation doses less than expected.


Company has decided to replace vessel heads of both 900 MW PWRs, taking advantage of long planned SG replacement in 1996 and 1998. Vessel heads are bigger than the containment buildings equipment hatches, but a hole must be cut in each containment in any case to remove the SG.
Cost of one vessel head are about US$ 4 million
