TURNING TRAINING FROM A COST INTO AN INVESTMENT

On September 30, 1999, Japan experienced the second worst civilian radiation exposure in its history at the Tokaimura fuels facility. Two technicians were performing routine work conducted in a similar manner for over the past seven years when a previously determined ‘impossible criticality event’ became an inevitability. The accident claimed two lives and exposed over 300,000 people living in proximity to the plant.[1] In little over a decade later, the worst nuclear materials accident occurred 250 miles away at the Fukushima Daiichi fuels storage facility, with the structural and biological damage already exceeding the $70 billion mark. Though the facilities differ in terms of their mission and scope of work, a common root cause was that both facilities either provided no training in an important area, such as the absence of fissile material handling fundamentals at Tokaimura, and the training provided was deemed ineffective.[2] Both facilities had a training department that at some point worked to an approved training plan. So, what happened?
