AARM - Robot for Operations in Nuclear Reactors

Use of robotics-based automation in the nuclear industry is a reliable and proven technology that has two distinct benefits. The first and most important benefit is that using robots and robotic tools for routine or extraordinary operations in a nuclear facility limits the exposure of personnel to radiation. 

The second benefit is the overall reduction in operating cost and increase in productivity and reliability that are associated with robotics in this industrial sector.

At the core of a CANDU nuclear reactor is the Calandria vessel. It contains a network of horizontal tubes for fueling the reactor.

After several decades of service these fueling tubes must be replaced in a process known as “re-tubing” of the reactor. It is of outmost importance that during this operation no debris or foreign matters remain inside the Calandria.

AARM - A robot arm and other custom systems supplied to be used to inspect the interior of nuclear reactor core.

AARM - A robot for such operations with the ability to pick up and remove any debris.

AARM - A robot inserted during a retrofit of a reactor through a lattice sleeve tube in the shielding wall of the reactor after the fueling and pressure tubes have been removed to perform inspection and repairs.
