Risk at a nuclear power plant can take many forms. Operators are concerned about factors that impact consistent, efficient energy production. Engineers are con- cerned about component reliability, compatibility and quality. All are focused
on safety on the job. As a result, plant managers seek methods of mitigating risk. Any
technique that is able to transform an “unknown” into a “known” factor is considered
Metrology, the science of measurement, offers an easy method of mitigating risk. In
fact, the smart application of modernized metrology techniques can have substantial
benefits for plant managers.
Now, the word “metrology” probably
makes most plant managers think
about as-built plans. Indeed, metrology
techniques such as laser scanning are most
commonly used to complete as-builts
after a construction project. However,
metrology goes far beyond this simple use.
There are many “tools in the toolbox”
when it comes to metrology. Measurement
technologies are ever evolving, getting more
precise and accurate. Modern metrology
