From NIA: New and updated reports on advanced nuclear

July 20, 2022, 7:00AMANS Nuclear Cafe

The Nuclear Innovation Alliance (NIA), a Washington, D.C.–based nonprofit, has released a new report, Advanced Nuclear Reactor Technology: A Company Compendium, along with an update to its Advanced Nuclear Reactor Technology: A Primer, first published last September.

Both reports are meant to serve as resources for investors, reporters, policymakers, regulators, and others wanting to learn more about the different technologies and key players involved in the design, licensing, construction, and operation of advanced nuclear reactors.

DOE-NE 2023 budget priorities summarized in ANS online program

A team from the Department of Energy’s Office of Nuclear Energy joined ANS Executive Director/Chief Executive Officer Craig Piercy on April 27 for an ANS members–only online event to discuss the Biden administration’s fiscal year 2023 NE budget proposal. The proposed total for the office, $1.675 billion, is more than a $20 million increase from the FY 2022 enacted level of $1.654 billion.

Input sought on Kairos test reactor construction permit

The Nuclear Regulatory Commission is requesting public input on environmental issues that the agency should ponder as it reviews Kairos Power’s application for a construction permit to build the Hermes low-power demonstration reactor at the East Tennessee Technology Park in Oak Ridge, Tenn.

In a notice published in the February 18 Federal Register, the NRC says it will conduct a scoping process to gather information necessary to prepare an environmental impact statement (EIS) for the proposed project.

The Tennessee Valley Authority’s board of directors has given the go-ahead for a program that will explore the development and potential deployment of small modular reactors as part of the utility’s decarbonization strategy.

Tennessee governor gives nuclear another rhetorical boost

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.”

Advanced reactors: Now comes the hard part

January 28, 2022, 2:26PMNuclear NewsMatthew L. Wald

Designing a reactor is complicated but building one may be harder. Even companies that have had lots of practice haven’t always done it well. And all the power reactors in service today were built by companies that had years of experience in other kinds of big steam-electric power plants. In contrast, some of the creative new designs now moving toward commercialization come from start-ups that have never built anything at all. How should they prepare?

2021 ANS Virtual Annual Meeting: CEO roundtable

June 18, 2021, 9:37AMNuclear News

The 2021 ANS Annual Meeting brought together three leading chief executive officers from the nuclear industry on June 16 for a discussion centered on the future role of nuclear energy deployment and the challenges of portfolio management during a time of net-zero carbon goals.

Advanced reactor economics and markets

TerraPower and GE Hitachi Nuclear Energy jointly developed the sodium-cooled Natrium reactor with the turbine hall, nitrate heat storage tanks, and cooling towers separated from the reactor at the back of the site.

The viability of nuclear power ultimately depends on economics. Safety is a requirement, but it does not determine whether a reactor will be deployed. The most economical reactor maximizes revenue while minimizing costs. The lowest-cost reactor is not necessarily the most economical reactor. Different markets impose different requirements on reactors. If the capital cost of Reactor A is 50 percent more than Reactor B but has characteristics that double the revenue, the most economical reactor is Reactor A.

The most important factor is an efficient supply chain, including on-site construction practices. This is the basis for the low capital cost of light water reactors from China and South Korea. The design of the reactor can significantly affect capital cost through its impact on the supply chain. The question is, how can advanced reactors boost revenue and reduce costs?
