Case Study - North Anna Nuclear Generating Station
North Anna Nuclear Generating Station
North Anna Nuclear Generating Station needed to find a resource that had the experience to implement a fire protection solution for their new transformers. The plant scheduled a two-week outage during which the installation was to occur. F.E. Moran Special Hazard Systems got the job done in half the time.
An Essential Source of Power to the Region
Located in Mineral, Virginia, the North Anna Power Station has been providing Virginia with power for more than thirty years. The site produces 1,806 megawatts of electricity from its two pressurized water reactors to provide electricity to 450,000 homes in the region. It is essential that the station operates at maximum uptime, as it serves as a major power source in the area. Any business interruption results in a major financial impact for the plant.
The Plant's Valuable Assets Demanded a Quality Fire Protection System
As the plant's transformers began to age, North Anna made the decision to replace three of its transformers during a scheduled two-week outage. High voltage transformers are inherently susceptible to fires due to insulation problems or lightning. These problems can result in volatile fires that can damage equipment, stop production and put lives at risk. Implementing a high-quality fire protection system is the best way to safeguard a power plant in the event of a transformer fire.
Seeking a Swift but Reliable Solution
Installing a reliable deluge sprinkler system was deemed the best fire protection solution for the plant. North Anna was faced with the challenge of finding a resource that had the expertise to install the system so that it would function optimally in this high-risk environment. In addition, they needed to find a reliable resource that could also install the system within the rigid two-week timeframe. It was necessary that the contractor be experienced and knowledgeable enough to design and fabricate the system in a way in which it could be quickly and efficiently installed.
Meeting Timelines to Avoid Financial Losses
With more than thirty years of experience providing power generating stations with comprehensive fire protection solutions, F.E. Moran Special Hazard Systems was a natural choice for North Anna. The knowledge that F.E. Moran has accumulated over the past three decades offered the proficiency needed to design and install fire protection systems quickly while still upholding the highest standards.
From the onset of the project, F.E. Moran's project management team carefully planned every facet of the installation to ensure that the project progressed efficiently and did not interfere with the coinciding work related to the transformers.
F.E. Moran's expertise gave them the ability to foresee potential issues before they resulted in subsequent labor delays.
The configuration of the deluge system that F.E. Moran implemented forms a protective ring around the transformers with nozzles every five feet. Protectowire Linear Heat Detector is used to detect fire, which in turn triggers the sprinkler system.
As the project progressed, the installation was well organized and was being implemented seamlessly.
Because of F.E. Moran's proficiency, the plant staff was able to devote their attention to the additional maintenance needed during the outage rather than being preoccupied with the sprinkler system installation.
The project manager and design team were intimately familiar with the application and synchronized well with the loss prevention team, which allowed them to finish the job in one week- only half the time that they had been allotted. North Anna did not have to worry about the enormous financial implications associated with extending their outage.
The system installed by F.E. Moran passed the extensive testing done onsite, which meant that plant staff were not sidetracked by the hassle of conditional reports.
