Unit 1 at the Taishan nuclear power plant in China has been shut down to examine fuel rod damage and conduct maintenance, China General Nuclear Power Group (CGN) reported last Friday.
Taishan, located in Guangdong Province, is home to twin 1,660-MWe EPRs, the first two such reactors in the world to enter commercial operation (in December 2018 and September 2019, respectively). The plant is owned and operated by Taishan Nuclear Power JVC (TNPJVC)—a joint venture of CGN; France’s EDF, which is also the majority owner of Framatome, the Taishan reactors’ designer and supplier; and the Guangdong Energy Group.
“At present, a small amount of fuel damage has occurred during the operation of Taishan Nuclear Power Unit 1, but it is still within the allowable range of technical specifications, and the unit can continue to operate stably,” CGN stated in its announcement. “After full communication between Chinese and French technical personnel, [TNPJVC] insists on safety first and conservative decision-making in accordance with nuclear safety regulations and nuclear power plant operating procedures …. The unit will be shut down for maintenance, find the cause of fuel damage, and replace the damaged fuel.”

Federal subsidies for nuclear plants?
Thu, May 6, 2021, 5:01AMANS Nuclear Cafe
The Biden administration has indicated to lawmakers that it supports federal subsidies for struggling nuclear power plants, Reuters reported this morning, citing sources familiar with the discussions.
The subsidies would be in the form of production tax credits, according to the report, and would likely become part of the president’s $2.3 trillion infrastructure plan.
“There’s a deepening understanding within the administration that it needs nuclear to meet its zero-emission goals,” states a Reuters source.
Last month, during the Leaders Summit on Climate, President Biden announced that the United States will target reducing greenhouse gas emissions by 50–52 percent by 2030, with the goal of achieving net-zero emissions by 2050 at the latest.

Study finds Estonia’s geology suitable for borehole repository
A preliminary study conducted by the nuclear waste storage and disposal startup company Deep Isolation found that Estonia’s geology is capable of safely hosting a deep horizontal borehole repository for radioactive waste from advanced nuclear reactors.
The study, commissioned by advanced reactor deployment company Fermi Energia, found no fundamental geologic limitations to disposing of nuclear waste in deep horizontal boreholes, according to Deep Isolation. In addition, the study noted that a wide range of locations could be demonstrated to comply with International Atomic Energy Agency regulations for geologic disposal.
The findings: Results of the study, which was conducted in collaboration with Estonian geologic and drilling company Engineering Bureau STEIGER, will be presented as part of Fermi Energia’s one-day conference on small modular reactors, "New Generation Nuclear Energy in Estonia," on February 9. Registration for the event is available online.
Study details: The study is a qualitative geological assessment of Estonia’s crystalline basement rock that evaluates geological conditions and potential risk factors for Estonia’s 15 counties, screening their potential for hosting a deep borehole repository. Such a repository would isolate radioactive elements from the earth’s surface for 1.3 million years, according to Deep Isolation.
Fermi Energia is developing plans to build a SMR in Estonia. Deep Isolation said that Fermi Energia is the first European company it has contracted to conduct a preliminary geologic study to manage advanced reactor waste.
Quote: “If we are to be successful in our efforts to see Estonia become the first European Union country to deploy an SMR in the 2030s, it is important that we take responsibility now in planning for spent fuel disposal,” said Kalev Kallemets, chief executive officer of Fermi Energia. “This Deep Isolation study indicates that a deep borehole disposal repository could meet all prerequisites and be safe and cost-effective as well as easily deployed and scalable.”

Five advanced reactor designs get DOE risk reduction funding
December 16, 2020, 3:00PM|Nuclear News Staff
The Department of Energy today announced $30 million in initial fiscal year 2020 funding—with the expectation of more over the next seven years—for five companies selected for risk reduction for future demonstration projects. The chosen reactor designs from Kairos Power, Westinghouse, BWX Technologies, Holtec, and Southern Company collectively represent a range of coolants, fuel forms, and sizes—from tiny microreactors to a molten salt reactor topping 1,000 MWe. They were selected for cost-shared partnerships under the Office of Nuclear Energy’s Advanced Reactor Demonstration Program (ARDP) through a funding opportunity announcement issued in May 2020.
“All of these projects will put the U.S. on an accelerated timeline to domestically and globally deploy advanced nuclear reactors that will enhance safety and be affordable to construct and operate,” said Energy Secretary Dan Brouillette. “Taking leadership in advanced technology is so important to the country’s future, because nuclear energy plays such a key role in our clean energy strategy.”
The awardees: The projects selected for risk-reduction awards could be licensed and deployed over the next 10 to 14 years. ARDP funding is intended to support the developers as they resolve technical, operational, and regulatory challenges to prepare for future demonstration opportunities.
Hermes Reduced-Scale Test Reactor, Kairos Power. Kairos Power, of Alameda, Calif., will design, construct, and operate its Hermes reduced-scale test reactor. Kairos plans to site the test reactor at the East Tennessee Technology Park in Oak Ridge, Tenn. Hermes is expected to lead to the development of Kairos Power’s commercial-scale KP-FHR (Kairos Power Fluoride Salt-Cooled High-Temperature Reactor), which uses TRISO fuel in pebble form combined with a low-pressure fluoride salt coolant. Total award value over seven years: $629 million (DOE share: $303 million).
eVinci Microreactor, Westinghouse Electric Company. Westinghouse Nuclear, of Cranberry Township, Pa., will advance the design of a heat pipe–cooled microreactor to support a nuclear demonstration unit by 2024. The project is to reduce technical risks associated with the moderator canister design, improve the ability to manufacture heat pipe wicks, and develop an economically viable refueling process and licensing approach. Total award value over seven years: $9.3 million (DOE share: $7.4 million).
BWXT Advanced Nuclear Reactor (BANR), BWXT Advanced Technologies. BWX Technologies, of Lynchburg, Va., plans to develop a commercially viable transportable microreactor using TRISO fuel particles to achieve higher uranium loading and an improved core design using a silicon carbide matrix.

Holtec SMR-160 Reactor, Holtec Government Services. Holtec, based in Camden, N.J., is receiving funding for early-stage design, engineering, and licensing activities to accelerate the development of Holtec’s light-water-cooled SMR-160. Total award value over seven years: $147.5 million (DOE share: $116 million).
Southern Molten Chloride Reactor Experiment, Southern Company Services. Southern Company, based in Birmingham, Ala., is designing, constructing, and operating the Molten Chloride Reactor Experiment to demonstrate the high-burnup capabilities of Southern’s liquid salt–fueled Molten Salt Reactor. Total award value over seven years: $113 million (DOE share: $90.4 million).
ARDP background: The DOE was directed by the Nuclear Energy Innovation Capabilities Act to establish the ARDP to help domestic private industry demonstrate advanced nuclear reactors. The program has three components: advanced reactor demonstrations, risk reduction for future demonstrations, and advanced reactor concepts 2020 (ARC 20).

In October 2020, the DOE announced the selection of TerraPower and X-energy to receive $160 million in initial demonstration funding to develop and construct two advanced nuclear reactors that can be operational within seven years. An announcement of ARC-20 funding, to support designs in their earliest phases with the potential to commercialize in the mid-2030s, is expected later this month.

Nuclear Waste Startup Gets Backing for Underground Storage Holes
Will Wade and Catherine Traywick, Bloomberg News

(Bloomberg) -- Deep Isolation Inc. raised $20 million from backers including NAC International Inc. to develop its system for storing deadly nuclear waste miles below the surface of the earth.
As part of the Series A funding round, NAC will also get a seat on Deep Isolation’s board, according to a statement Wednesday. The deal values the Berkeley, California-based company at $60 million.
Deep Isolation hasn’t yet received a license from the Nuclear Regulatory Commission for its borehole technology, and the firm doesn’t have customers that have agreed to use it. But potential clients have expressed interest in the idea, the company said.
“We need clean energy,” Chief Executive Officer Elizabeth Muller said in the statement. “In the case of nuclear power, this means finding a permanent solution for nuclear waste.”
Deep Isolation estimates that the global nuclear-waste disposal market is worth $660 billion. While there’s wide consensus that spent fuel rods should be stored deep underground, the only U.S. proposal for a national repository in Nevada has been stalled for decades because of local opposition. The company’s technology addresses this issue by proposing to bury waste near reactors, as an alternative to existing above-ground storage sites.
NAC International is a Georgia-based nuclear services company that’s been working with Deep Isolation since last year.

フェッセンハイム原子力発電所
仏EDF、フェッセンハイム2号機を恒久停止
07 Jul 2020
仏国内すべての原子力発電所を所有・操業するフランス電力(EDF)は6月29日、ドイツとの国境に近い東部に立地するフェッセンハイム原子力発電所2号機(PWR、92万kW)を、同日夜11時に恒久停止したと発表した。同炉は国内で稼働中の原子力発電所としては最古となる1978年に営業運転を開始、昨年9月に公表されていた予定日より1日前倒しの停止となった。
これは、2015年8月に成立した「エネルギー移行法」に基づき、現在約75%の原子力発電シェアを2025年までに50%に削減し、原子力発電設備も2015年レベルの6,320万kWに制限するための施策。これらの施策は元々、F.オランド前大統領が当時公約していたもので、手始めとして、フェッセンハイム発電所で1977年に運転開始した1号機(PWR、92万kW)が今年2月に恒久停止された。
