Crossing the Finish Line at Watts Bar

Joey Ledford
Public Affairs Officer
Region II

Watts Bar Unit 2, the nation’s first new commercial nuclear unit in a generation, received its NRC operating license last October and is closing in on its first nuclear chain reaction. (Power production is still a ways off.) The NRC is still on the job as the staff transitions to operational inspection duties.

The agency’s Region II-based construction inspection staff, supplemented by headquarters staff, have booked more than 127,000 hours making sure the new unit has been built according to its design specifications. More than 350 agency inspectors and other staff have been involved in the inspection and project management effort, which geared up in earnest in 2008 when the Tennessee Valley Authority committed to completing the unit it had initially started building in 1973 and later suspended.

The Watts Bar plant, located about 50 miles northeast of Chattanooga, Tenn., has a unique history. Unit 1, which also traces its roots to 1973, was the last U.S. plant to come on line when it was finally licensed in 1996 after a similarly lengthy construction hiatus.

When work resumed on Unit 2, the NRC recalled a handful of staffers who had been involved in inspecting work on the sister unit to ensure “knowledge transfer.”

“Our goal is to verify the design is accurate,” said James Baptist, who was a team leader for several years during Watts Bar 2 construction and has recently become chief of the Region II branch overseeing the transition from construction to operation. “We want to ensure Unit 2 looks and operates just like Unit 1. It greatly assists the effort when you have a working model right beside you.”

As is the case with most NRC inspection efforts, the corps of construction resident inspectors led the way, reporting to the site daily and amassing a big percentage of those 127,000 hours.

“Everything came through the residents in terms of what was going on at the site,” said Chris Even, who recently transitioned from senior construction project manager to senior project inspector in the new branch overseeing the transition. “We always relied on the residents for knowing exactly what was going on.”

The workload was huge from the beginning, with more than 550 construction inspection items to be inspected and closed. And Baptist noted that even though the plant was designed in the 1970s, it’s built to today’s standards.

“They purposely built Unit 2 to be a mirror image of Unit 1 while including all the updated safety enhancements that have accrued over the last 25 or 30 years,” he said.

For example, Watts Bar is the first plant in the nation to comply with all the NRC’s post- Fukushima upgrades as well as the newest cybersecurity requirements.

One might think that with the license issued and the plant about to start up that the NRC inspection effort would be winding down. Baptist said that is not the case.

“We still have our foot on the gas,” he said.

Just as the NRC inspectors were dedicated to make sure Watts Bar Unit 2 was constructed and tested according to the design and NRC regulatory requirements, they will continue to maintain that vigilance as the plant begins and continues to operate.

 

 

Plainly Telling the Public about Our Environmental Reviews

Tomeka Terry, Project Manager
Office of New Reactors

The NRC feels it’s important to write our documents so that all readers can understand them. We’ve previously discussed writing in plain English and acronym use. The agency’s made extra effort to write plainly in its documents most read by the public, and to reduce the use of acronyms when we can.

We use many tools to inform the public about who we are and what we do. Our work is technical and some documents must meet legal standards, but we still want people to understand as much as possible. So we went a step further—creating a new tool to improve understanding and reduce reading effort.

Environmental impact statements help the NRC decide whether to approve projects, such as licensing the building and operating of a nuclear power plant. Each environmental impact statement for a new reactor will now include a “Reader’s Guide” with a simple, short overview of the statement. The Reader’s Guide summarizes the project’s potential environmental impacts. It also describes alternatives and ways to reduce the effects the project would have on the environment.

We’ve also included an overview of the NRC’s new reactor licensing process and opportunities for public participation in the Reader’s Guide.

The brochure format makes understanding the environmental impact statement easier. Most NRC environmental impact statements average 1500 pages, while the Reader’s Guide gives an overview in about 40 pages.

The Reader’s Guide also helps us conserve resources. When we send our documents to the public, we can now print a short document and include the full environmental impact statement on an enclosed CD.

Two recent Reader’s Guides cover a draft environmental impact statement for a proposed new reactor in Pennsylvania and a final environmental impact statement for a site in New Jersey.
