GOING NUCLEAR - HDTV 2008

When big machines experience problems, they often require big solutions. Master rigger and host Sean Riley discovers how these heavy duty industrial fixes are made, on everything from high voltage electricity lines to nuclear power plants, and meets the specialists charged with putting things right.

Sean attends one of his most dangerous fixes yet, upgrading a 70-tonne steam turbine in a nuclear power plant. But even though the reactor has been shut down, the worksite is still a potential radiation zone. Clothed in his hazmat suit, Sean witnesses a task rarely seen as he joins the army of technicians who must carry out the job.
