Example text

DECOMMISSIONING EXPERIENCE AND TECHNOLOGIES FOR UNDERGROUND PIPING Piping is a major grouping in underground decommissioning projects. However, the subject of underground piping relates to more than just piping itself. Many directly related components include fittings, valves, instruments, wall penetrations and hangers. The subject area also includes components connected by piping, such as pumps, sample collection devices, sumps, compressors and vessels (tanks are the subject of Section 7). Buried pipes transferring contaminated fluids between buildings or tanks were a common feature at nuclear facilities designed and starting operations in the period from the 1940s to the 1970s.

Other invasive methods include sewer snakes and water jetting. While these methods can be effective, they can also create a significant problem with contamination cleanup and personnel exposure. However, the experience of the UK (Annex V) indicates satisfactory application of water jetting there. A pulsed hydraulic system has been developed which uses the differences between the resonant vibrations of the fluid column and pipe walls to separate the blockage from the pipe wall, break the blockage up and clear the line [111].

Additional detail is given in the technical literature, for example Refs [1, 2, 4, 5, 40, 41]. 1. CHARACTERIZATION OF PHYSICAL, RADIOLOGICAL AND HAZARDOUS MATERIALS An overview of innovative and emerging technologies is provided here. A number of these techniques were developed, deployed and optimized in actual decommissioning operations with funding from the United States Department of Energy to cope with the enormous legacy of redundant nuclear facilities in 25 FIG. 4.
