Denmark-based Seaborg Technologies, developer of the compact molten salt reactor (CMSR), has teamed with two South Korean firms—shipbuilder Samsung Heavy Industries (SHI) and nuclear plant owner and operator Korea Hydro & Nuclear Power (KHNP)—to form a consortium for the development of floating nuclear plants featuring the CMSR. The consortium agreement was signed in Seoul on April 20.

Looking back at 2022—October through December

January 6, 2023, 9:09AMNuclear News

Another calendar year has passed. Before heading too far into 2023, let’s look back at what happened in 2022 for the American Nuclear Society and the nuclear community. In today's post that follows, we have compiled from Nuclear News and Nuclear Newswire what we feel are the top nuclear news stories from September through December 2022.

But first:

First unit at Shin-Hanul begins commercial operation

Unit 1 at South Korea’s Shin-Hanul nuclear power plant entered commercial operation last week, Korea Hydro & Nuclear Power has announced. The 1,340-MWe APR-1400—designed by KHNP and parent firm Korea Electric Power Company—achieved initial criticality on May 22 of this year and was connected to the grid on June 9.

Bids in for new unit at Dukovany

A Westinghouse-Bechtel team, France’s EDF, and Korea Hydro & Nuclear Power have all submitted their initial bids for securing the contract to build a fifth reactor at the Czech Republic’s Dukovany plant, Czech utility ČEZ has announced.

Westinghouse to build Poland’s first nuclear reactors; KHNP may get separate deal

Poland has chosen Westinghouse Electric Company to supply the reactors for its initial nuclear power plant, as the Central European nation seeks to lessen its dependence on domestic coal and Russian imports for its energy supply. On Friday, Polish prime minister Mateusz Morawiecki announced the decision on Twitter, confirming last week’s reports that Westinghouse’s AP1000 technology was the government’s likely choice.

“A strong [Polish-American] alliance guarantees the success of our joint initiatives,” Morawiecki tweeted. “After talks with [vice president Kamala Harris and energy secretary Jennifer Granholm], we confirm our nuclear energy project will use the reliable, safe technology of [Westinghouse].”

Competing with the American firm for the job were Électricité de France and Korea Hydro & Nuclear Power. In October 2021, EDF submitted an offer to build four to six EPRs in Poland, while KHNP offered in April of this year to construct six APR1400 units.

Following a meeting in Washington, D.C., on Sunday with secretary of energy Jennifer Granholm, Polish deputy prime minister Jacek Sasin told reporters that his nation is close to choosing the reactor supplier for its initial nuclear plant project, adding, according to Bloomberg, “There is a big chance that we will finally pick Westinghouse.”

And in a news release on the meeting from the Polish government, Sasin is quoted as saying, “The massive energy crisis that is currently affecting us means that we must quickly make decisions on building the country’s energy security based on new, clean, cheap, and reliable sources, and such a source is nuclear energy. We want the decisive decisions to be made as soon as possible. That is why we asked [Granholm] for a meeting, during which we will clarify all the issues that remain to be clarified.”

Korea Hydro and Nuclear Power (KHNP) has signed a contract with Atomstroyexport JSC—the engineering division of Russia’s Rosatom—to build the turbine islands for Egypt’s El Dabaa nuclear power plant, construction of which commenced just last month with the pouring of first concrete.

South Korea’s new president, Yoon Suk-yeol, appears to be following through on his campaign pledge to reverse the previous administration’s domestic nuclear phaseout plan. Earlier this month, Yoon’s Ministry of Trade, Industry, and Energy announced a new direction for the nation’s energy policy—one that calls for, among other things, a reembrace of nuclear power. A further announcement on the subject last week provided additional details.

EDF makes latest move to build EPRs in Poland

June 28, 2022, 12:00PMNuclear News

Électricité de France has signed cooperation agreements with five Polish companies as it continues its efforts to be named the large-reactor supplier for Poland’s incipient nuclear power program.

Polish firms Polimex Mostostal, Sefako, Tele-Fonika Kable, Uniserv, and ZRE Katowice inked the pacts at the fifth Polish-French Nuclear Industry Day in Ołtarzew, Poland. According to EDF, the event was held to foster collaboration between Polish and French companies in support of the utility giant’s offer to deliver four to six EPRs for the Polish program.

Canadian Nuclear Laboratories (CNL) and Korea Hydro and Nuclear Power (KHNP) intend to leverage data collected over decades on the dry storage of spent nuclear fuel to help inform decision-making on future spent fuel storage, transportation, and disposal activities.

Orano has delivered its first TN-LC spent nuclear fuel transport cask to Korea Hydro and Nuclear Power Company. The first use of the cask is planned for an international transport between South Korea and Sweden by the end of 2021.

KHNP received a license in June for the TN-LC transport cask from the Nuclear Safety and Security Commission, South Korea’s regulatory agency, for the transport of high-burnup spent fuel.

With the signing of a cooperation agreement by Orano and Korea Hydro & Nuclear Power at KHNP’s headquarters in Gyeongju on December 4, France and South Korea are poised to enhance collaboration in the decontamination and decommissioning of nuclear facilities, particularly in South Korea and Europe.

Orano said that the collaboration will give it access to the expertise of KHNP engineers, as well as to KHNP’s network of providers of nuclear engineering services, particularly in the fields of robotics, process industrialization, and quality.

KHNP, in return, will benefit from Orano’s experience in preparing and carrying out nuclear dismantling, with the company providing technical assistance and supplying skills and training. South Korean engineers will be included in the Orano dismantling and services teams.

Over the past four years, the South Korean nuclear power program has suffered a set of very public setbacks that cast doubt on the entire program's integrity, to the point where even the South Korean president's attention was directed at the enterprise, in addition to public support being damaged. A recent well-publicized realignment in energy policy has seen a reduction in the expected percentage that nuclear energy would contribute to South Korea's fuel mix, and in some quarters it was augured that the program had been crippled.
