Crystal River Nuclear Power Plant Unit 3, Drop Load Analysis

Crystal River, FL

The Crystal River Nuclear Power Plant Unit 3 is part of the 4,700 acre (19 km²) Crystal River Energy Complex which contains a 914 MW pressurized water reactor.

When the client planned rigging operations for the replacement of a steam generator at Unit 3, they required an assessment of potential damage to buried structures in the event of an accidental drop of the components. They also required verification or modification of safe lifting load paths to avoid failure of the water cooling system needed to operate during the replacement process. As a part of the planning for steam generator replacement, SGH assessed the following primary buried structures under drop loads: 120-foot sea water room concrete wall, 48-inch diameter raw water discharge PCCP lines, 90-inch diameter circulating water PCCP Lines, and 48-inch diameter raw water intake ductile iron lines. We also inspected the 12 inch fire service lines, 18 inch storm sewer lines, and 4 inch floor drains.
