Power station event analysis
This resource from the IET Faraday programme, supported by MEI and Tomorrow's Engineers, provides students with the opportunity to explore the risk of failure of safety systems in a power station.
"A Power station experiences a loss of coolant to its reactor about once per year. To prevent a dangerous explosion, a set of controls are in place. Firstly an alarm which alerts the operator, this works on 99% of occasions. If this does fail various other systems will become operational to monitor the issue and prevent disaster."
The resources include a presentation that introduces the key concepts and a series of questions for students to explore. The activity overview includes lesson suggestions, discussion points, answers and links to the curriculum. A student handout is also included, as is a and spreadsheet that generates data for a thousand trials and a frequency tree showing all possible outcomes.
