Development of the Nuclear Safety Information Dashboard - September 2012

September 2012

A working group with nuclear safety expertise used paired pairing computer software to develop first, a severity-weighted factor for the 17 Groups of ORPS Reporting Criteria and then, a severity-weighted factor for the sixty-five ORPS reporting criteria.

The sum of the severity-weighted factors for the sixty-five ORPS Reporting Criteria equals 100%. Paired pairing is an analytical tool used to determine weighted factors. A team evaluated pairs of ORPS reporting criteria and concurred on the relative importance of each pair. Each ORPS reporting criterion in a group was compared with one other ORPS reporting criterion in the group until each unique combination of pairs was evaluated. A computer program was used to combine the results for each “paired pair” in the group and calculate the weighted factor for each ORPS reporting criterion.
