This week I had some considerable interaction on social media in the area of replacing fossil power at existing sites with micro reactors or SMR’s (Small Modular Reactors.) As we see real progress happening now in these exciting reactor fields (NuScale and Oklo come to mind first, but there are others!) I’d like to share five things to think about as we begin to seriously consider replacing fossil power (coal, oil) at particular sites with nuclear.

NextEra Energy announced on February 11 that its bid to buy South Carolina’s public utility, Santee Cooper, is the “recommended purchase proposal” following a formal bid invitation called for by the state’s General Assembly in May 2019 (NN, June 2019, p. 9). Competing with NextEra’s purchase offer is a reform plan put forward by Santee Cooper in an attempt to avoid a sale as the utility continues to grapple with the failed Summer-­2 and -­3 nuclear construction project and the $3.6 billion in debt incurred before the project was halted in July 2017.

A report from the South Carolina Department of Administration published on February 11 outlined the competing plans and factors that the General Assembly may want to take into consideration as it mulls the plans. A third option, a proposal by Dominion Energy to take over the management, but not the ownership, of Santee Cooper was also evaluated.

A study released by Energy Northwest on January 30 concludes that more and different electricity sources, including nuclear, will be needed to maintain energy reliability and achieve a carbon-­free energy system in the state of Washington by 2045. The study used published conservation and efficiency projections and costs and examined the value of creating additional solar and wind facilities, as well as extending the operation of the Columbia nuclear power plant beyond 2043 and deploying small modular reactors.

“Completing this study is simply the first step in a much larger decision-­making process,” said Brad Sawatzke, Energy Northwest’s chief executive officer. “Any decision to invest in new resources will take time and will only be done in the best interest of our member utilities, the people of Washington, and, of course, the environment.”

The Department of Energy was directed by the Nuclear Energy Innovation Capabilities Act of 2017 to establish the Advanced Reactor Demonstration (ARD) Program to stimulate commercial enterprises in advanced reactor deployment and facilitate U.S. private industry’s demonstration of several advanced reactors with the capability to achieve reliable, cost-­effective, and licensable designs. The ARD program was launched on February 5 with a request for information (RFI) and notice of intent (NOI) issued by the Office of Nuclear Energy’s Office of Reactor Fleet and Advanced Reactor Deployment.

The Nuclear Regulatory Commission has announced an opportunity to request an adjudicatory hearing regarding Southern Nuclear’s notice of intended operation of Unit 3 at the Vogtle nuclear power plant, located in Waynesboro, Ga. The announcement was prompted by a January 13 letter from Southern Nuclear notifying the NRC of its scheduled date of November 23, 2020, for initial fuel loading at the reactor. As required under 10 CFR 52.103(a), the notification was made more than 270 days prior to the scheduled fuel load.

A combined license was issued for Vogtle-­3 and -­4, Westinghouse-­designed AP1000 pressurized water reactors, in February 2012. The license covers both construction and operation after construction is completed if standards—known as inspections, tests, analyses, and acceptance criteria (ITAAC)—identified in the combined license are satisfied. Operation will not be permitted until the NRC staff finds that all ITAACs have been met. However, if a hearing request is granted, the NRC can allow interim operation, given reasonable assurance of adequate protection of public health and safety while the adjudicatory hearing is carried out.

Our ANS Nuclear Cafe Friday Matinee feature this week is a film produced to detail the United States Army’s nuclear power program; it was archived and then put online by the US Army Corps of Engineers, Baltimore.

The U.S. Energy Information Administration is projecting that U.S. electricity generation from nuclear power will most likely decline from its 2019 share of about 20 percent to 12 percent by 2050. In addition, the agency sees generation from coal declining by 11 percent, from 24 percent to 13 percent.

According to the EIA’s Annual Energy Outlook 2020, released in late January, nuclear and coal will experience a substantial falloff over the next few years—the result of slow load growth and the increasing electricity production from renewables, which is expected to grow from 19 percent to 38 percent over the next 30 years—but will then plateau to collectively provide about 25 percent of the nation’s electricity through the century’s midpoint.

Referencing the findings of the Intergovernmental Panel on Climate Change, as well as its own “strong history of environmental stewardship,” Dominion Energy on February 11 announced that it is expanding its greenhouse gas emission–reduction goals by pledging to achieve net-­zero emissions by 2050. The new goal covers emissions of carbon dioxide and methane—the two leading greenhouse gases—from the company’s electricity generation and gas infrastructure operations.

“Our mandate is to provide reliable and affordable energy safely,” said Thomas F. Farrell II, Dominion’s chairman, president, and chief executive officer. “We do that every day, all year long. But we recognize that we must also continue to be a leader in combatting climate change. . . . Dominion Energy already has made important progress on emissions. This new commitment sets an even higher bar that I am confident we can, and will, reach. Net-­zero emissions will be good for all of our stakeholders—for our customers, communities, employees, and investors.”

President Trump’s budget request for fiscal year 2021, released on February 10, allots $35.4 billion to the Department of Energy. Nearly $1.2 billion of that goes to the Office of Nuclear Energy (DOE-NE).

The final FY 2020 appropriations were signed into law on December 20, 2019, nine months after that budget was first proposed, and it could be several months before final appropriations for FY 2021 are enacted. Those enacted appropriations could bear little resemblance to the proposed budget. It bears noting that while the FY 2020 budget request for DOE-NE was $824 million, more than $1.493 billion—an increase of just over 87 percent—was ultimately enacted.

This morning the White House released its FY2021 budget request. We don't expect federal agencies to issue their detailed budget requests—known as Congressional Justifications, or "CJ's"—for another week or two. In the meantime, here's what we know now:

March 26, 2019, marked the 20th anniversary of the first shipment of transuranic (TRU) waste to the Waste -Isolation Pilot Plant (WIPP) facility in southeastern New Mexico. Celebrations of the 20-year mark of waste operations recognized the role of the WIPP facility in cleaning up legacy TRU waste from 22 generator sites nationwide.

The U.S. Nuclear Waste Technical Review Board (NWTRB or Board) recently completed an evaluation of Department of Energy activities related to transporting spent nuclear fuel (SNF) and high-level radioactive waste. These topics have been the subject of several Board meetings and associated reports, and in September 2019, the Board issued a report, Preparing for Nuclear Waste Transportation–Technical Issues That Need to Be Addressed in Preparing for a Nationwide Effort to Transport Spent Nuclear Fuel and High-Level Radioactive Waste [1], which focuses on the issues DOE will need to address to plan and implement an integrated transportation program. In its report, the Board describes 30 broad technical issues that DOE needs to address and offers three sets of findings and recommendations.
