Genie in the Bottle
In the case study, Genie in the Bottle, maintenance workers removed a high worth control rod from a nuclear reactor causing a nuclear accident. Explain what kind of error this was and why. What would have been the best way to prevent this error? Give an example of how to do this in the Genie case.
(1x 1)This error was a ___________________________________________________.
The workers in this story made a mistake (1). No other answer would be accepted in this case.
(2x3) Explain why.
Because they didn’t understand the type of control rod (1) and the workings of the reactor they operated with the wrong intention (1), (to raise the rod higher), making this a mistake. The actions(raising the rod higher)(1) they took were correct given their intention.
(1x1) The best way to prevent this would have been by _______________________________.
This error could have been prevented through the use of a forcing function (1) We would also accept physical barrier or physical constraint. Other solutions are only worth half marks.
(2x2) This would be the best way because
A forcing function is the best way because it does not require training or manuals (1) and physically makes removal of the rods impossible to do(1).
(1x1) An example of this would be __________________________________________
An example of this would have been a physical barrier (1) which would have prevented the workers from removing the rod too far.
