With a design that has just emerged from a rigorous safety evaluation by the Nuclear Regulatory Commission, and a customer—Utah Associated Municipal Power Systems (UAMPS)—getting ready to prepare a combined license (COL) application, what is next for Oregon-based NuScale Power and for near-term small modular reactor prospects in the United States? As milestones are reached, many want to know.

NuScale plans to supply twelve 60-MWe modules for a 720-MWe plant—called the Carbon Free Power Project (CFPP) by UAMPS—to be sited at Idaho National Laboratory. A smaller, 50-MWe module version of NuScale’s design recently became the first SMR to receive a final safety evaluation report (FSER) from the Nuclear Regulatory Commission.

“The NRC design approval represents a significant de-risking factor for the CFPP,” said UAMPS spokesperson LaVarr Webb. The project is “making steady progress,” Webb said, adding that “UAMPS General Manager and CEO Doug Hunter has said it is much more important to do the project right than to do it fast.”

More voices come to the defense of Ohio’s H.B. 6 policy

September 8, 2020, 12:06PMNuclear News

Despite high-profile calls to repeal the scandal-tainted Ohio Clean Air Program Act (H.B. 6) and recent legislation crafted toward that end in both the Ohio House and Senate (66 of 99 House members have reportedly co-sponsored Democratic or Republican bills to repeal H.B. 6), the policy behind the measure continues to garner support.

As reported here on August 26, the six commissioners from Ohio’s Lake and Ottawa counties—home to Davis-Besse and Perry, the two nuclear plants saved from early closure by H.B. 6—have made clear their opposition to an immediate repeal of the act.

September 4, 2020, 12:07PMNuclear News

The National Academies of Sciences, Engineering, and Medicine (NAS) has begun a new webinar series, with the first entry titled “What’s new in low-dose radiation.” The July 22 event kicked off the Gilbert W. Beebe Webinar Series—an extension of the Beebe Symposium, which was established in 2002 to honor the scientific achievements of the late Gilbert Beebe, NAS staff member and designer/implementer of epidemiologic studies of populations exposed to the atomic bombings of Hiroshima and Nagasaki as well as the Chernobyl accident.


Duke companies include advanced nuclear in plans to speed carbon reduction

September 4, 2020, 9:38AMNuclear News

Duke Energy Progress and Duke Energy Carolinas have filed their 2020 Integrated Resource Plans (IRPs) with state regulators, parent company Duke Energy announced September 1.

The plans outline a range of options to achieve varying levels of carbon reduction, including, for the first time, potential pathways to achieve up to 70 percent carbon-emission reduction through policy and technology advancements.

Aggressive carbon-reduction targets are attainable, the company said, with investments in solar, wind, and energy storage, as well as with advanced nuclear, offshore wind, and other technologies “as they become available.” (Last September, Duke Energy declared its intention to seek subsequent license renewal for the 11 reactors it operates in six nuclear plants in the Carolinas [NN, Oct. 2019, p. 9].)

DOE grants $29 million for fusion energy R&D

September 4, 2020, 6:59AMNuclear News

The Department of Energy announced on September 2 that it has issued $29 million in funding for 14 projects as part of its Galvanizing Advances in Market-aligned fusion for an Overabundance of Watts (GAMOW) program, which is jointly sponsored by the department’s Advanced Research Projects Agency–Energy (ARPA-E) and the Office of Science–Fusion Energy Sciences (SC-FES).

According to the DOE, GAMOW teams will work to close multiple fusion-specific technological gaps that will be needed to connect a net-energy-gain “fusion core,” once it is ready, to a deployable, commercially attractive fusion system.

The Natrium reactor and energy system architecture, recently introduced by TerraPower and GE Hitachi Nuclear Energy (GEH), offers baseload electricity output from a 345-MWe sodium fast reactor with the load-following flexibility of molten salt thermal storage. Stored heat can be used to boost the system’s output to 500 MWe for more than five and a half hours when needed, according to TerraPower. A company representative told Nuclear News that the company expects a commercial Natrium plant to cost $1 billion or less.

Rosenergoatom, the electric power division of Rosatom, Russia’s state-owned nuclear power corporation, announced on August 31 that Leningrad II-2 has achieved initial criticality. The unit is one of two Generation III+ VVER-1200 pressurized water reactors at the Leningrad nuclear plant.

Leningrad II-2 is scheduled for commercial start early next year, replacing Leningrad I-2, a 925-MWe RBMK-1000 light-water–cooled graphite-moderated reactor that will permanently cease operation at the end of 2020 after 45 years of service. Fuel loading at Leningrad II-2 began in July.

Special inspection begins at Turkey Point

EDF Energy has received approval from the United Kingdom’s Office for Nuclear Regulation (ONR) to restart the Hunterston B power station’s Unit 3 for a limited run, according to August 27 announcements from both the company and the regulator. EDF has permission to operate the unit for up to 16.425 terawatt days (approximately six months of operation), the ONR said.

EDF also announced that Hunterston B—located in North Ayrshire, along the western coast of Scotland—will begin its defueling phase no later than January 7, 2022, more than a year earlier than the expected retirement date of March 2023. The decision, EDF said, was made following a series of executive board and shareholders meetings.

The final safety evaluation report for NuScale Power’s small modular reactor design has been issued, completing the design’s technical review and approval, the Nuclear Regulatory Commission announced on August 28.

The NRC will now prepare a rulemaking to certify the NuScale design. Full certification, if granted by the commissioners following the staff’s recommendation, will allow a utility to reference the design when applying for a combined license to build and operate a nuclear power plant.

The NuScale design is the first SMR to receive NRC design approval.

Can chemical heat pumps for integrated energy systems and industrial applications change the world?

August 28, 2020, 3:27PMNuclear NewsVivek Utgikar, Piyush Sabharwall, and Brian Fronk

Nuclear energy is faced with a number of challenges in a changing energy landscape, driven by the need to reduce carbon emissions to mitigate climate change. Renewable energy technologies are being considered as the solution to climate change and are increasingly being deployed across the world. However, renewable energy sources, particularly solar and wind, are highly variable, and deployment of these technologies has resulted in significant perturbances in the energy market, raising questions about grid stability and the adaptability of other sources to compete in a changing marketplace that prioritizes renewables. Nuclear plants, well suited for baseload operation, have demonstrated technical capability and flexibility to respond to the fluctuating demand; however, they have also discovered that the economics of such operating mode are not necessarily optimal to their financial security. On the other hand, despite contributing to the carbon emissions, the low cost of abundantly available natural gas and resultant low-cost electricity have exacerbated the economic pressure on nuclear technologies, raising questions about their survival and role in future energy systems1.

INL continues to fine-tune TREAT testing capabilities

August 28, 2020, 10:25AMNuclear News

Idaho National Laboratory’s Transient Reactor Test Facility, also known as TREAT, returned to service in 2017 after a hiatus of more than two decades. To make full use of TREAT’s capabilities, researchers at INL created the Minimal Activation Retrievable Capsule Holder (MARCH) test vehicle system, which, according to an August 26 Department of Energy press release, can cut years off the development process for nuclear fuels and materials and allow new clients, like NASA, to take advantage of TREAT’s capabilities.
