The latest upgrade at the nuclear power plant is the Fast Acting Platform, designed by Unified Engineering and Bruce Power‘s Human Factors department.
Did you know that risk analysis suggests mitigating incidents by implementing and strengthening, what they call, barriers. Deciding which barrier to use is a trade-off between effectiveness and resources required. Among the most effective barriers are physical and engineering barriers. Risk analysis was the seed to the RAB Fast Acting Platform which has fall prevention railings and 4 strategic fall arrest anchor loops. It can be maneuvered by 2 people, despite it’s weight, with grab bars at comfortable heights for handling.
Custom to this job, it had to be lifted in from one side, as if landing inside a tunnel, to fit under the reactor and rest on the limited support beneath.
In the end, the job has become safer and reactor maintenance schedule has also benefited incredibly. By removing the scaffolding installation and removal processes, 90 man hours were eliminated. Now, it requires 4 people for 1.5 hours to install the platform. This is how proactive obsolescence pays off, in the end.
