- Started Commercial Operation: Unit 1 (1976), Unit 2 (1983)
The St. Lucie Nuclear Power Plant stands as the second-largest nuclear facility in Florida, generating enough clean energy to power over a million homes.
Technical Details
Both units at St. Lucie utilize pressurized water reactors (PWRs). In a PWR, uranium fuel generates heat, which is transferred to water in a closed loop. This hot water doesn’t come into contact with the water that produces steam to spin the turbines. Instead, it heats a secondary loop containing water at a lower pressure, which then boils into steam to drive the turbines and generate electricity. This design feature helps to prevent radioactive contamination of the water used for steam generation.
Environmental Impact
One of the significant advantages of St. Lucie is its minimal greenhouse gas emissions during electricity generation. This makes it a crucial player in Florida’s clean energy mix.
Emergency Preparedness
The surrounding communities are prepared for any potential emergencies through comprehensive plans and public education initiatives. Regular drills and exercises ensure a well-coordinated response system in place.
The Future of St. Lucie
The operating licenses for both St. Lucie units have been extended, with Unit 1 running until 2036 and Unit 2 reaching its expiration date in 2043. Public discussions regarding the future of the plant beyond these dates are likely to take place as they approach.
3. Crystal River Nuclear Power Plant (Unit 3 – Decommissioned)
The Crystal River Nuclear Power Plant, unlike the previously mentioned stations, has a different story to tell. Once a contributor to Florida’s energy needs, it’s now a decommissioning project.
History of Crystal River
Located in Citrus County, Florida, the Crystal River Nuclear Power Plant housed a single pressurized water reactor. Here’s a quick recap of its past:
- Units: 1 (Pressurized Water Reactor – Decommissioned)
- Capacity: 860 Megawatts (MW)
- Owner: Duke Energy Florida
- Started Commercial Operation: 1979 (Shut down in 2013)
The plant began generating electricity in 1979. However, its operation came to an end in 2013 following a significant containment building crack. The Decommissioning efforts officially began in 2019.
Decommissioning Process
Decommissioning refers to the safe and gradual dismantling of a nuclear power plant. It’s a complex undertaking that can take many years to complete. In the case of Crystal River, the process is expected to last for approximately 60 years.
During decommissioning, the radioactive materials are removed from the site and disposed of in federally approved repositories. The remaining structures are then decontaminated and demolished.
Crystal River Energy Complex
It’s important to note that the Crystal River site encompasses more than just the decommissioned nuclear plant. The Crystal River Energy Complex also houses operational natural gas and oil-fired units that continue to generate electricity for the region.
The Future of the Crystal River Site
The future of the Crystal River site remains uncertain. Once decommissioning is complete, the land could be used for other purposes. However, there are no definitive plans in place at this time.
4. Levy Nuclear Power Plant (Construction Canceled)
The Levy Nuclear Power Plant was a proposed two-unit nuclear power plant in Levy County, Florida. However, due to economic reasons and concerns following the Fukushima Daiichi nuclear disaster in Japan, construction was canceled in 2*13. The partially built structures remain on the site.
Here’s a quick look at the Levy Nuclear Power Plant project:
- Location: Levy County, Florida
- Units: 2 (Planned – Construction Canceled)
- Capacity: 2,200 Megawatts (MW)
- Owner: Duke Energy Florida (License Withdrawn)
