Bulgarian officials have approved the transition to Westinghouse fuel at the nation's Kozloduy nuclear power plant, as Bulgaria moves away from its reliance on Russian supplies. The fuel was recently delivered for use in Unit 5.

Bulgaria has shortlisted South Korea’s Hyundai Engineering and Construction team to build new reactors at Kozloduy nuclear power plant.

Of the five international companies to bid on the project, Hyundai E&C was the only one that met the requirements of project company Kozloduy NPP—New Builds Plc. for the commissioning and construction of two new Westinghouse Electric AP1000 reactors, the Bulgarian firm said. Bids were due February 2.

Officials from the United States and Bulgaria inked a deal this week to cooperate as Bulgaria further develops its civil nuclear power program.

A working group will explore plans to design, construct, and commission two new units at Bulgaria’s Kozloduy nuclear power plant. The two countries will also “explore collaboration on research and training programs and developing Bulgaria's nuclear supply chain resilience,” according to reports.

To help speed up commercialization of its eVinci microreactor, Westinghouse Electric Company this week launched a new design and manufacturing facility for the project near downtown Pittsburgh, Pa. Located in the borough of Etna, the 87,000-square-foot eVinci “accelerator hub” will be home to engineering and licensing operations, testing, prototype trials, business development, and sales, Westinghouse said in an October 24 announcement, adding that the facility will include manufacturing space for producing the “innovative heat pipes that are central to the eVinci technology.”

The energy ministries of Bulgaria and Ukraine have announced the signing of a memorandum of understanding to expand collaboration in the energy sector, including the nuclear energy sector.

The European Union has selected a Westinghouse-led consortium to develop and deliver “a secure, fully European nuclear fuel supply” for Russian-designed VVER reactors in the EU and Ukraine, the U.S.-based firm announced last week.

Westinghouse Electric Company this week inked agreements with two of its European customers—Ukraine reactor fleet operator Energoatom and Bulgaria’s Kozloduy NPP–Newbuild, a firm established in 2012 to commission new nuclear power capacity at Kozloduy, Bulgaria’s only nuclear power facility.

Continuing to move forward with its ambitions in Central and Eastern Europe, Westinghouse Electric Company last week signed a memorandum of understanding with Kozloduy NPP–Newbuilds (KNPP-NB), establishing a working group to initiate planning for the potential deployment of one or more of the American company’s AP1000 reactors at Bulgaria’s Kozloduy nuclear power plant.

KNPP-NB was established in 2012 to commission new nuclear power capacity at Kozloduy.

The working group, according to a March 2 Westinghouse announcement, will also evaluate regulatory, licensing, and design bases to ensure compliance with applicable regulations, as well as a streamlined execution path to enable Bulgaria to achieve its nuclear energy goals.

Westinghouse Electric and Framatome have signed agreements with Kozloduy NPP—the eponymous operator of Bulgaria’s only nuclear power facility—to fabricate and deliver fuel for the site’s two operating reactors. Westinghouse will provide the fuel for Unit 5 under a 10-year contract inked on December 22, while Framatome will supply Unit 6 under a December 30 preliminary deal. First deliveries of fuel from Westinghouse and Framatome are expected in 2024 and 2025, respectively.

The two agreements, according to the Bulgarian News Agency, “are part of an effort to diversify energy supplies to Bulgaria and do away with the country’s dependence on Russian energy resources.” In November, the Bulgarian National Assembly approved 156–47 a resolution tasking the country’s Council of Ministers with licensing non-Russian nuclear fuel for Kozloduy.

This is the second of five articles to be posted today to look back at the top news stories of 2021 for the nuclear community. The full article, "Looking back at 2021,"was published in the January 2022 issue of Nuclear News.

Quite a year was 2021. In the following stories, we have compiled what we feel are the past year’s top news stories from the January-March time frame—please enjoy this recap from a busy year in the nuclear community.

Nuclear power will remain the dominant source of electricity generation in Bulgaria until 2030, despite the national government’s plans to add a substantial amount of renewable capacity this decade, says GlobalData, a U.K.-based data and analytics company. (According to a national strategy blueprint published on the Bulgarian parliament’s website last year, the country is targeting an additional 2,645 MW of installed capacity from renewable sources by the end of 2030.)

Bulgaria’s Kozloduy nuclear plant

Portland, Ore.–based NuScale Power has signed a memorandum of understanding with Kozloduy Nuclear Power Plant–New Build Plc (KNPP-NB) to discuss the possible deployment of NuScale’s small modular reactor technology at Bulgaria’s Kozloduy site. KNPP-NB was established in 2012 to commission new nuclear power capacity at Kozloduy.

Specifics: Under the MOU, NuScale will support KNPP-NB as it analyzes the suitability of NuScale’s SMRs for Kozloduy, located in northwest Bulgaria. The analysis will include the development of a project time line “with milestone deliverables for a feasibility study” and a project-specific cost estimate, as well as engineering, planning, licensing, and other activities, according to a February 17 NuScale press release.

Bulgaria has become the 34th member of the Paris-based OECD Nuclear Energy Agency (NEA). With its several decades of experience operating VVER units, Bulgaria will reinforce the NEA’s capacity to address matters related to pressurized water reactor technologies and their operational characteristics, according to the NEA on January 4.

In addition, the NEA said that it will support Bulgaria’s efforts in technical and policy areas, including work to address nuclear skills capacity building, the development and application of nuclear data and simulation codes, and issues related to radioactive waste management, decommissioning, and nuclear economics.

The United States in the past few weeks has signed civil nuclear agreements with Romania and Poland, and now a third European nation can be added to the list: Bulgaria.
