Counting the Steps to a Final Watts Bar Unit 2 Decision

The NRC’s Commissioners have given the staff the authority to issue the Tennessee Valley Authority (TVA) a full-power operating license for Unit 2 at the Watts Bar nuclear power plant site in Tennessee. That permission has some strings attached, however, so we’re still months away from our final licensing decision.

TVA still has to satisfy the staff that several regulatory requirements for safe operation of Unit 2 have been met. We’re finishing up the licensing and inspection activities we need to conclude TVA is ready to load fuel and operate the reactor, which is near Spring City, Tenn.

We have to be satisfied not only that Unit 2 is safe to operate, but also that TVA can safely transition to operating two reactors at the site. We’re completing a few licensing actions needed to support dual-unit operation at Watts Bar. TVA also has to pass our remaining operational readiness inspections.

Other upcoming milestones include getting a recommendation from the NRC’s Region II Administrator, who has oversight responsibility for all inspections performed at Watts Bar 2. We also need to issue a couple supplements to the reactor’s Safety Evaluation Report.

TVA’s progress in completing construction and testing of Watts Bar 2 will directly influence our completion of the milestones. We may be able to make a licensing decision later this year. TVA has said repeatedly, however, that the actual operating license date depends on several factors and could shift as the final months’ work is completed. While we take TVA’s schedule into consideration for planning our licensing and inspection work, our priority is always on ensuring safety.

If we conclude Unit 2 is safe and ready to receive a license, TVA will still have to successfully complete several tests, including running the reactor at gradually increasing power levels, before the reactor can provide electricity to the grid. The NRC website has more information on the past few years of Watts Bar Unit 2’s licensing and inspection activities.

Listen In On Our Watts Bar Unit 2 Meeting with TVA

The NRC’s been closely observing the Tennessee Valley Authority’s work in completing Unit 2 at the wattsbarWatts Bar Nuclear Plant near Spring City, Tenn. Our meeting tonight will discuss where TVA stands in its effort to get an operating license for Unit 2.

If you can’t make it in person, we’re offering a teleconference and Web-based access to the meeting presentation. You can get the phone and webinar details from me or my NRC co-worker Christopher Even. For those who can attend, we’ll be available to answer questions and discuss issues with local residents and interested members of the public.  

During the meeting we’ll lay out the inspections and licensing activities the NRC must complete before we could decide whether Watts Bar 2 qualifies for an operating license. Some of our senior managers will explain how we’ve reached this point and what we need to see before we could conclude that the plant is safe to operate.

While we’re still reviewing a few issues, all the information we’ve seen so far indicates TVA is on track to meet the safety and security requirements for a reactor operating license.

If we issue Watts Bar Unit 2 an operating license, TVA would still have to load fuel and begin a series of tests during plant startup and a gradual increase in power output. The NRC would continue inspecting and overseeing the completion of these startup activities prior to Unit 2 generating full power and starting commercial operation. If licensed, Unit 2 would be the first plant to begin commercially operating in the U.S. since Watts Bar Unit 1 started in 1996.
