Molten Salt Reactor to Be Built at the Idaho Lab

terrapower logoTerraPower and Southern Company announced they have agreed to demonstrate the world’s first fast-spectrum salt reactor at Idaho National Laboratory. The Molten Chloride Reactor Experiment will provide crucial operational data for fast-spectrum salt reactors and unlock this uniquely flexible advanced reactor technology for use in a net-zero future.

The Molten Chloride Reactor Experiment will be the world’s first fast-spectrum, salt-fueled nuclear fission reactor to go critical.

Selected for funding under the U.S. Department of Energy’s (DOE) Advanced Reactor Demonstration Program (ARDP), the MCRE project will advance TerraPower’s Molten Chloride Fast Reactor (MCFR).

Southern Company research and development will lead the effort in a collaboration that includes TerraPower, INL, CORE POWER, Orano Federal Services, the Electric Power Research Institute and 3M Company.

The team’s ongoing alliance with DOE’s Office of Nuclear Energy through the ARDP is essential for delivering this key technology and will be supported by a five-year, $170 million cost-shared funding agreement.

According to the press statement, the MCRE project “represents a significant inflection point in the technology demonstration roadmap for TerraPower’s MCFR,” as the project will inform the design, licensing and operation of an MCFR demonstration reactor. MCRE is targeted for operation at INL.

As a research reactor it will have a different licensing profile than a reactor intended to be deployed for electrical power generation.

An environmental review will be completed for the MCRE project in accordance with the National Environmental Policy Act before final design and construction begins. MCRE’s first criticality is scheduled for late 2025.

“TerraPower is eager to continue its partnership with Southern Company – an established energy company that offers a crucial perspective and expertise to further position our Molten Chloride Fast Reactor technology for success,” said Chris Levesque, TerraPower’s president and CEO.

Berry, Southern Company vice president of R&D.

TerraPower’s MCFR technology offers many performance and economic benefits including flexible, highly efficient clean power generation as a complement to the increased use of intermittent renewables on the grid. The MCFR technology also has the potential to provide carbon-free, high-grade process heat and thermal storage for difficult-to-decarbonize industrial markets and ocean transportation sectors.

Through a public-private partnership that was initiated in 2015, Southern Company and TerraPower joined DOE and others in the nearly $80 million project building integrated infrastructure necessary to support early development of the MCFR technology.

Czech Gov’t to Release Tender for a PWR at Dukovany

Prime Minister Petr Fiala said in an interview with Czech Television the government will publish a planned tender to build a multi billion-dollar nuclear power unit at CEZ’s Dukovany plant in the coming weeks.

The Czech government will call a planned tender to build a multi billion-dollar nuclear power unit, slated to be in the range of 1200 MWe, at CEZ’s Dukovany plant. Prime Minister Petr Fiala said in an interview with Czech Television on Sunday.

United States, France’s EDF and South Korea’s KHNP are expected bidders. Russia and China have been excluded from bidding on security grounds.

Czech authorities dropped Russia from the tender, estimated to be worth at least 6 billion euros ($6.79 billion), in April last year amid a heated diplomatic dispute with Moscow over a deadly blast at an arms depot in 2014. Russia denied involvement but the arms were intended to be shipped to Ukraine and the Czech government charged Russia with accountability for the blast.

Fiala said under tender plans, a supplier for the new Dukovany unit could be picked in 2024 and construction permits obtained by 2029. He said it was necessary to commission the unit by 2036. Nuclear power is an important energy source in the Czech Republic, accounting for 40% of its energy mix. The new unit is meant to replace facilities set to retire in the coming decades.

The project is to be backed by state zero-interest loans, as well as state-guaranteed power purchases at profit for CEZ, which is 70% owned by the state. The country won some tweaks to the inclusion of nuclear power projects in the European Union’s hotly debated green investment plans this month as it waited to go ahead with the Dukovany project.

NuScale Inks MOU with Wisconsin Coop

NuScale and Dairyland Power Cooperative announced collaboration to explore the deployment of NuScale’s SMR. Headquartered in La Crosse, Wisconsin, Dairyland is a generation and transmission cooperative providing the wholesale electrical requirements for distribution cooperatives and 17 municipal utilities, supplying the energy for more than a half-million people in four states (Wisconsin, Minnesota, Iowa and Illinois).

Under this MOU, the two parties will work together to explore NuScale’s small modular reactor technology and support Dairyland’s due diligence process in evaluating affordable, reliable and carbon-free energy solutions.

In support of Dairyland’s existing portfolio, NuScale’s SMRs are positioned as being flexible and able to perform load following maneuvers to meet grid capacity needs due to the intermittency of wind, solar, and hydro generation, facilitating the growth of renewables.

Additionally, NuScale’s technology is particularly well-suited for placement at retiring coal plant sites, preserving critical jobs in the energy industry and helping host communities facilitate the transition to a decarbonized energy system.

“NuScale is thrilled to partner with an environmentally-focused, forward-thinking organization like Dairyland,” said John Hopkins, NuScale Power President and Chief Executive Officer.

“Dairyland is examining carbon-free power supply technologies including NuScale’s small modular reactor nuclear plants,” said Brent Ridge, Dairyland President and CEO.

Ghana / Site For First Commercial Nuclear Reactor Will Be Chosen ‘By End Of Year’

(NucNet) Nuclear Power Ghana (NPG) said it will choose a preferred site for the country’s first commercial nuclear power station by the end of this year. The African country hopes plant will begin operation by 2030,

NPG, a limited liability company with a mandate to lead the construction and operation of the proposed nuclear station, has identified four candidate sites for the project, according to press reports in the west African country.

NPG executive director Stephen Yamoah said the body is analyzing historical data on the four identified sites. He said NPG would produce a site approval report which would be submitted to the regulator for review.

“We have received a host of historical data from over 12 institutions on issues such as seismology and issues of flooding,” he said. “We have received information from the Ghana Statistical Service in terms of population and projected population growth.

“All these are criteria that we factor into the site selection because the nuclear power plant will not be built in a populated area, so we need to know the present population and the projected,” Mr Yamoah said.

In October 2019, the International Atomic Energy Agency said Ghana had made progress implementing recommendations of a 2017 IAEA integrated nuclear infrastructure review (INIR) mission. That review had provided 12 recommendations and eight suggestions to help Ghana in making progress in its nuclear infrastructure development.

However, the IAEA said more recently that further work was needed in areas such as government funding, stakeholder involvement planning, fuel cycle options for the first nuclear power plant and goals for local participation.

In October 2021, press reports said five nuclear reactor vendors had responded to a request for interest issued by Ghana to collaborate with the African country in its planned nuclear power program. The reports, quoting an environment ministry official, did not name any companies, but said the vendors were from the US, Russia, Canada and South Korea.

Kenya Seeks Public Views on 4000MWe Nuclear Power Project

kenya nuc logoKenya’s Nuclear Power and Energy Agency (NuPEA) is seeking public views on a nuclear power project that will be set up in Kwale or Kilifi. The move follows a decision last year, now apparently reversed, to zero out any government spending on new nuclear power plants.

According to NuPEA Head of Legal Services Justus Wabuyabo, the government has identified Kwale and Kilifi as the most preferred sites for the nuclear power station due to their less likelihood of suffering earthquakes.

An environmental impact assessment (EIA) will also be conducted in the proposed location to determine the viability of the $5 billion (Sh575 billion) nuclear plant.

NuPEA expects four reactors of 4,000MWe to be on site by 2035. The aggressive schedule and enormous cost of the project are well beyond Kenya’s means which raises the question of why it is setting these milestones.
