The Steam Generating Team (SGT)—a joint venture of Framatome and United Engineers & Constructors Inc.—has completed a project to replace the Unit 2 steam generators at the Watts Bar nuclear plant, Framatome announced last week.

Watts Barr’s owner and operator, the Tennessee Valley Authority, awarded Framatome the contract for the work in early 2020.

Collecting belt buckles from nearly every nuclear power plant in the U.S. wasn’t the goal for Don Hildebrant when he obtained his first one. Over time, it just turned out that way.

One day years ago, Hildebrant came across a buckle from the nuclear plant where he worked, and it seemed before he knew it, he had collected more than 250 of them—some from plants that were never even completed. “When you look at the collection, you will see an interesting story of where nuclear power has been, and how far it has come,” he said.

In his annual State of the State Address on January 31, Tennessee Gov. Bill Lee offered more praise for nuclear energy, after lauding it earlier in the month during a tour of the Tennessee Valley Authority’s Watts Bar nuclear plant

“For decades, East Tennessee has been home to some of the best-kept secrets in nuclear energy and American innovation,” Lee told the state’s General Assembly. “Today, many may not realize that Tennessee derives more power from nuclear energy than from any other source. Recently, I visited the TVA’s Watts Bar nuclear facility, the last nuclear facility to be built in America, to see firsthand how nuclear power keeps our grid dependable even when the weather is not. Nuclear power is clean energy that actually works for the private sector.”

During a tour last week of the Tennessee Valley Authority’s two-unit Watts Bar nuclear power plant in Tennessee, Gov. Bill Lee said, "Nuclear energy is so important not only because it is an important part of TVA's power generation but also because of the value that clean energy via nuclear energy can have for sustainability in this country,” according to an article in the Chattanooga Times Free Press.

Lee added that he would support TVA’s plans if it decided to build small modular reactors.

The Nuclear Regulatory Commission has granted Dominion Energy’s request for an increase in the generating capacity of Millstone-3. The Richmond, Va.–based utility had applied for the power uprate last November, requesting an increase of approximately 1.6 percent.

NRC staff determined that Dominion could safely increase the reactor’s heat output, primarily through more accurate means of measuring feedwater flow, according to a November 18 press release. The NRC’s safety evaluation focused on several areas, including the nuclear steam supply systems, instrumentation and control systems, electrical systems, accident evaluations, radiological consequences, fire protection, operations and training, testing, and technical specification changes.

The Nuclear Regulatory Commission recently released its Enforcement Program Annual Report for calendar year 2020, showing a total of 61 escalated enforcement actions taken last year against licensees, non-licensees, and individuals—an increase of 7 percent from CY 2019, but a number that remains below the five-year (2016–2020) average.

Construction and maintenance services firm Day & Zimmermann (D&Z) has paid $200,000 to resolve allegations that it submitted false claims to the Tennessee Valley Authority for services performed in connection with capital improvement projects at the Watts Bar nuclear plant, the U.S. Attorney’s Office for the Eastern District of Tennessee announced last week.

One week after issuing a six-figure civil penalty to the Tennessee Valley Authority for violating Nuclear Regulatory Commission rules involving employee protection, the NRC has proposed penalties totaling more than $900,000 on TVA for a 2015 incident at the utility’s two-unit Watts Bar nuclear plant, located near Spring City, Tenn.

The NRC also has issued violations to two managers and a reactor operator for their roles in the incident.

The enforcement actions are the result of an NRC investigation—initiated in August 2016 and completed in May of last year—into events that occurred during and after the startup of Watts Bar-1 following a maintenance outage in November 2015.

The Nuclear Regulatory Commission has approved a request from the Tennessee Valley Authority to increase the generating capacity of Unit 2 at the Watts Bar nuclear power plant by 1.4 percent, according to an October 27 press release from the agency. TVA submitted its application for the power uprate on October 10, 2019, and the NRC issued the required license amendment on October 21.

The power uprate, which TVA intends to implement by mid-December, will increase Unit 2’s generating capacity from approximately 1,223 MWe to 1,240 MWe.

“The NRC staff determined that TVA could safely increase the reactor’s output, primarily through more accurate means of measuring feedwater flow,” the press release stated, adding, “NRC staff also reviewed the TVA evaluations demonstrating that the plant’s design can safely handle the increased power level.”

In actions related to its rules involving employee protection, the Nuclear Regulatory Commission on August 24 issued a proposed civil penalty of $606,942 to the Tennessee Valley Authority, as well as an order prohibiting a senior TVA executive from NRC-licensed activities for five years and a violation notice to a second executive.

Following investigations completed in October 2019 and January 2020, the NRC concluded that two former TVA employees had been subjected to reprisals for raising concerns regarding a chilled work environment.
