Large Diameter Pipe Replacement at Nuclear Plant

Large Diameter Pipe Replacement at Nuclear Plant

 March 2012 March2012 FPL StLucieNuclearPlt1UESI performed support work and excavation to allow pipefitters to replace two 60’ sections of pipe that discharges into the Nuclear Plant discharge canal. Due to the configuration of the canal, UESI had to remove revetment concrete and build a coffer dam to retain 28’ of dirt and 16’ of water. Soil under the pipe was compacted to 98% to meet QC requirements. After removing the concrete revetment, a 14’ deep void was discovered. UESI worked with the utility to find a method of repair that would prevent failure of any surrounding structures.
