Overview

672 buckets—but only 12 days

The challenge

GE Steam Power—working in collaboration with our on-site services, FieldCore and APM teams—was faced with a daunting job: Replace 672 buckets across three low-pressure (LP) nuclear steam turbines at a U.S. nuclear power plant, all in under two weeks.

The solution

Based on extensive planning, the GE team took project execution to new heights during a major outage. Pre-planning began nearly a year earlier, and included parts inventory reviews, up-front mitigation plans covering 25 potential risk factors, and even a “continuous motion” plan that enabled an around-the-clock work schedule—24 hours a day, seven days a week. 

Outcomes

Unprecedented teamwork

"

This was Steam Power’s first project involving the ‘re-bucketing’ of three nuclear steam turbine rotors simultaneously, and it was the largest-ever single mobilization for the On-Site Services team. Great planning, execution and attitude made this milestone project a true success.

Not only did the project team finish the job, but it also shaved nearly five days off the outage schedule. While “under the hood,” the team also completed a generator leak repair along with control valve and generator inspections. The entire project was accomplished with zero environment or health-and-safety incidents.

“The GE team did an excellent job,” wrote the plant’s outage manager. “Great planning, great execution, great attitude.” As a result of the shortened outage, the site was able to restart days ahead of schedule and, in turn, generate additional revenue by supplying power to its local metropolitan area.
