Abstract
The use of cured-in-place pipe (CIPP) and Carbon Fiber Reinforced Polymer (CFRP) liners for the rehabilitation of nuclear power plant raw water systems can result in significant cost savings, increased system reliability, and extended piping life. These systems also include the use of internal mechanical seals. The cost advantage for installation of CIPP alone may reach 10:1 for the nuclear power industry versus excavation and replacement of buried carbon steel piping. This paper will present recent examples of these applications, including unique requirements faced in the nuclear industry such as more detailed material and system qualification, licensing, and working within outage and operational restrains, e.g. Limited Condition of Operation (LCOs).
