Utility sets goal of net-­zero emissions by mid-­century

New Orleans–based Entergy Corporation last week announced a commitment to achieve net-zero carbon emissions by 2050, joining a growing list of major energy companies to make that promise—including Dominion Energy, Duke Energy, Southern Company, Xcel Energy, and Public Service Enterprise Group. And, like those companies, Entergy says that it sees nuclear playing an important role in the realization of that goal.

Stephen A. Byrne, former executive vice president of SCANA Corporation, pleaded guilty in federal court on July 23 to conspiracy to commit mail and wire fraud in connection with the failed $9-billion nuclear-expansion project at South Carolina’s Summer plant.

Byrne, 60, had also been president of generation and transmission and chief operating officer at SCANA subsidiary South Carolina Electric & Gas, overseeing all of SCANA’s nuclear operations, including the construction of the new nuclear units, on which work was stopped in 2017 (NN, Aug. 2017, p. 17).

A circuit court judge on July 20 gave final approval to a $520-million settlement in a class action civil suit brought against Santee Cooper over alleged deceptive business practices involving the failed nuclear-expansion project at South Carolina’s Summer plant.

Santee Cooper was the junior partner to SCANA Corporation’s South Carolina Electric and Gas in the two-reactor project, which was canceled in July 2017 (NN, Aug. 2017, p. 17). In July 2019, SCANA became a wholly owned subsidiary of Virginia-based Dominion Energy (NN, Feb. 2019, p. 15).

According to the lawsuit, brought by ratepayers, Santee Cooper raised rates to cover the increasing costs of the Summer expansion even after becoming aware that the project was no longer viable.

Virginia-based Dominion Energy has agreed to pay $25 million to settle a Securities and Exchange Commission (SEC) case regarding the Summer nuclear expansion project, abandoned by owners SCANA and Santee Cooper in 2017, prior to the Dominion/SCANA merger.

The Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) has issued a report recommending approval of Dominion Energy’s 20-year subsequent license renewal (SLR) application for Surry-1 and -2. The board reached its conclusion during its April meeting, after reviewing both the SLR application and the associated final safety evaluation report. Dominion submitted the application in October 2018.

The Nuclear Regulatory Commission issued its final supplemental environmental impact statement (EIS) on April 6 for Dominion Energy’s subsequent license renewal (SLR) application for Surry-1 and -2, concluding that the potential environmental impacts from continued operation of the units are not substantial enough to prevent the agency from considering issuance of the SLRs. The NRC had issued its final safety evaluation report on the Surry SLR application on March 9, with a similarly positive conclusion.

Now how did that get there?

Finding foreign material in your reactor system is not the beginning of a good day. Where did it come from? Did someone leave this in here or did something break? When did this happen? These are all good questions for which we need to know the answers.
