Drywell corrosion stopped at oyster creek

Inspections at GPU Nuclear's Oyster Creek nuclear power plant located in Forked River, New Jersey, revealed areas of corrosion on the outside of the drywell containment vessel. The corrosion had to be stopped before it could weaken the well's structural integrity and affect the containment...

Description
Summary:Inspections at GPU Nuclear's Oyster Creek nuclear power plant located in Forked River, New Jersey, revealed areas of corrosion on the outside of the drywell containment vessel. The corrosion had to be stopped before it could weaken the well's structural integrity and affect the containment's ability to perform its design function. Although repairing corrosion damage of this kind was a fairly straightforward task for the utility, gaining access to the corroding sections of Oyster Creek's drywell vessel was extremely tough. With an 8-foot-thick shield wall of reinforced concrete and high levels of radioactivity in the way, the utility's engineers were challenged to devise a workable plan. The utility's solution to this problem is detailed.
