Steam Generator Replacement
Since the first steam generators were replaced at Virginia Power’s Surry Unit 1 nuclear facility, PCI has been at the forefront of Steam Generator Replacement Projects (SGRPs). PCI’s continuous development of processes and technologies for use on SGRPs and processes for metrology, cutting, machining and machine narrow groove welding of heavy wall Reactor Coolant System (RCS) piping helped establish many world records for SGRPs.

Stuck Stud Removal
After almost 10 years and 600 stuck studs later, PCI still is the leading innovator in stuck stud removal. Utilizing the MDM cutting method, customers find that the type of stud material is of no significance. And, unlike drilling, the harder the material, the faster the process. Since MDM does not employ a drill bit, thread damage is rare and it takes from 50%-75% less time than the conventional drilling process.
