Underwater repairs in irradiated water
solve the problem
ASI Group Ltd. was contracted by Bruce Power located in Tiverton, Ontario, Canada,
to perform underwater repairs for the transfer cart system cable and tow bar which
were damaged during a spent fuel transfer operation without a plant shutdown.
This repair had to be performed and successfully completed as soon as possible as
storage space in the primary bay was limited and all four reactors were slated to be
shut down within 14 days if the transfer cart system could not be repaired in time.
Radiation was present in both the primary and secondary bays. The nature of the
radiation was both fixed and loose. Fixed radiation could be identified and isolated,
loose radiation had to be continually monitored. All dive personnel were aware they
would potentially receive some form of a radiological dose throughout the project.
This was the very first dive of its kind in Canada on a reactor system and in
irradiated water.
ASI provided the following services:

Bruce Power was very pleased with the speed of response and completion of the
repair. ASI has since worked with Bruce Power on two other nuclear dive projects.
