**The challenge was to design and construct a remotely controlled, boom-type robotic arm system to investigate the nature and location of nuclear fuel debris in the highly radioactive and contaminated environment of the disabled Unit 2 Reactor.**

Our solution was The Primary Containment Vessel Investigation (PCVI) System consisting of a 21m long boom-type robotic arm which is housed in an air-tight enclosure and maintained by a DexterTM manipulator.

The boom will be deployed, with tools and imaging systems mounted on it, through a small port in the side of the reactor building to move around inside the damaged reactor vessel.
