ACFM

Nuclear Applications

Nuclear power stations contain many components common to other power stations, such as turbines and pipework, which can be inspected by ACFM. However, the industry presents the additional problem that inspection may have to be carried out in a radioactive environment.

TSC have produced radiation tolerant probes for inspecting nuclear facilities, particularly storage tanks for radioactive waste. The probes produced for these applications are typically array probes designed for deployment by robotic manipulator or crawler. This method of inspection is preferred due to the high level of radioactivity that prevents the use of a human operator.

ACFM is also capable of detecting and sizing surface-breaking defects in the austenite stainless steel welds, or transition welds between austenitic and ferritic steels commonly found in the nuclear industry.

Other components that have been inspected in the nuclear industry include j-tube welds, and the threads on containment bolts.
