Listen In On Our Watts Bar Unit 2 Meeting with TVA

Jeanne Dion
Project Manager
Office of Nuclear Reactor Regulation

 
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.

Watts Bar – Making History In Yet Another Century

Unit 1 at the Watts Bar Nuclear Plant in Spring City, Tenn., has a claim to fame as the last U.S. commercial nuclear reactor to come online in the 20th century. Now, the Tennessee Valley Authority aspires to have its sister reactor (Watts Bar Unit 2) make its own historic claim.

Numerous cranes helped complete construction of the Watts Bar Nuclear Plant Unit 1 containment building in front of the plant’s cooling towers in 1977.

If the NRC concludes that the reactor is safe to operate and approves its operating license next year, Watts Bar Unit 2 could become the first new commercial nuclear reactor to come online in the U.S. in the 21st century.

To understand a little of the history of Watts Bar Nuclear Plant, let’s rewind to a time when Schoolhouse Rock premiered and the first mobile phone call was made in New York City — a time predating the NRC. In 1973, the Atomic Energy Commission greenlighted construction of Watts Bar Units 1 and 2 under the “two-step licensing process,” where construction permits and operating licenses were issued separately.

In 1985, construction quality issues at its plants caused TVA to stop work at both Watts Bar Units. Eventually, TVA resolved the issues and completed construction of Unit 1, and the NRC issued its operating license in 1996.

Fast-forward to more recent activities. TVA decided in 2007 to reboot the Watts Bar Unit 2 construction and licensing process. They submitted an update to their original license application to the NRC in 2009.

Other recent applicants have elected to use the combined license application process, where we issue a single license to both construct and operate a nuclear power plant at a specific site. However, because of the unique history of Watts Bar Unit 2, TVA chose to continue under the two-step licensing process. So, NRC staff developed a regulatory framework and established a licensing approach tailored specifically to the project.

We updated our construction inspection program associated with the two-step licensing process to provide guidance that reflects current NRC practices. For example, the NRC staff identified areas for further inspection at Unit 2 by screening applicable communications, allegations and other open items in the review.

The NRC staff also developed inspection guidance specific to TVA’s refurbishment program, which replaces or refurbishes systems and components at Watts Bar Unit 2. TVA’s resolution of key safety issues and the continued progress of construction inspection activities drive our review schedule.

If the operating license is issued next year, the NRC’s job doesn’t just end. We’d continue to inspect start-up testing required for power ascension and to oversee that Unit 2 transitions into the NRC’s Reactor Oversight Process before it can begin producing commercial power.

And, of course, the Resident Inspectors, the agency’s eyes and ears at the plant, would continue to carry out day-to-day inspection work to ensure safety and security is monitored and inspected during licensing and throughout the transition to commercial operation.
