Parts Quality Initiative
How Does PQI Work?
Step 1: DATA
A PQI Membership includes a subscription to Exelon’s web-based OneLab portal, which reveals Exelon’s extensive PQI Analysis database comprised of proven PQI test plans for more than 2,000 models and historical failure trends on more than 70,000 parts.
Since 2006, Exelon has compiled data revealing trends in failure variables specific to part type, manufacturer and model number for safety and non-safety single point vulnerability applications.
Step 2: TEST
Send hardware to one of Exelon PowerLabs’ sites for PQI critical characteristics testing. PQI ensures defective parts are identified before inventorying and installation, reducing downtime, labor and logistics costs. Testing newly procured parts before inventorying allows failed parts to be replaced for free within the warranty window, resulting in substantial cost savings. PowerLabs can also PQI test inventoried parts to verify older parts still perform their critical function.
