摘要

The ice condenser floors of a nuclear power plant had heaved upward and were binding against steam-vent doors. By drilling wells into the floors, insulating them, and thawing the ice beneath them, a large amount of water was pumped from the insulation beneath the floors. As a result, they dropped and created needed floor-to-door clear-ance. Although the partially dewatered floors are heaving again, they should not rise enough to become the problems they once were. In addition, the wells are in place for periodic dewatering should the need arise.
