Duke Energy – McGuire Nuclear Station
The Merrick Group returned to McGuire Nuclear Station in September of 2015 and March of 2016.
This time around the plant asked that we hydrolaze their feedwater heaters as an alternative to shooting swivel U-tube scrappers to remove the iron oxide build-up on the tubes. We performed this work on (4) feedwater heaters in September and (6) feedwater heaters in March. In addition to the feedwater heater work we cleaned, dimple plugged, and plugged tubes in the condenser water boxes. We also performed maintenance on other heat exchangers throughout the outage. The Merrick Group also assisted Taprogge in performing maintenance on the amertap system. We will be returning to McGuire in the spring of 2017.
