The Thermal Hydraulic Experimental Test Article (THETA) at Argonne National Laboratory is now operating and providing data that could support the licensing of liquid-metal fast reactor designs by validating thermal-hydraulic and safety analysis codes. The new equipment has been installed in Argonne’s Mechanisms Engineering Test Loop (METL), and its first experiments are supporting data validation needs of Oklo, Inc., by simulating normal operating conditions as well as protected and unprotected loss-of-flow accidents in a sodium-cooled fast reactor.

Energy Harbor has signed a memorandum of understanding with blockchain company Standard Power to develop a large-scale carbon-free data infrastructure operation adjacent to the Beaver Valley nuclear plant, located in Shippingport, Pa.
In its May 9 announcement, Energy Harbor described Standard Power as “a leading infrastructure service provider for advanced data processing companies and a leading hosting provider for blockchain mining companies.”
Energy Harbor is based in Akron, Ohio.

The United Kingdom’s energy minister, Greg Hands, recently presided over the opening of one of three new training centers in England aimed at supporting EDF Energy’s Hinkley Point C nuclear build project in Somerset. The centers, according to EDF, will provide locals with the skills necessary to join the ranks of about 4,000 additional workers expected to be needed for the next phase of the power station’s construction. Hands unveiled the Welding Centre of Excellence, located on the Bridgwater & Taunton College campus in Bridgwater.
The accident at Three Mile Island revealed many areas for improvement in the safety of nuclear power that have been addressed continuously in the past 40 years.
Part one of this article, published in the May 2019 issue of Nuclear News[1] and last Friday on Nuclear Newswire, presented insights from the 1979 accident at Three Mile Island-2 and addressed several issues raised by a previous Nuclear News piece on the accident[2]. Part two discusses safety improvements that have been made by both the industry and the Nuclear Regulatory Commission over the past 40 years.

Finnish energy company Fennovoima has terminated, effective immediately, its engineering, procurement, and construction (EPC) contract with RAOS Project Oy, a subsidiary of Russia’s Rosatom, for the delivery of a 1,200-MWe VVER-1200 pressurized water reactor at the Hanhikivi site in Finland’s Pyhäjoki municipality.
A pair of Westinghouse AP1000 reactors at China's Haiyang nuclear power plant.
China’s State Council recently approved the construction of four Westinghouse AP1000 reactors—two at China’s Sanmen plant in Zhejiang Province and two at the Haiyang plant in Shandong Province.
The plants currently house two AP1000 units each. Sanmen’s reactors are rated at 1,157 MWe and Haiyang’s at 1,170 MWe. Sanmen-1 and -2 began commercial operation in 2018. Haiyang-1 started commercial operation in 2018, and Haiyang-2 in 2019.

Concrete structures built to last for decades, including reactor containment buildings and other nuclear power plant structures, are subject to the alkali-silica reaction (ASR), a reaction between alkali ions found in cement and silica, the two main components of concrete. The reaction forms a gel that absorbs water and expands over time, causing a buildup of pressure within the concrete that can eventually lead to cracking and deterioration.
Researchers at Argonne National Laboratory have successfully used electrochemical impedance spectroscopy (EIS) to detect ASR in the lab and believe it could be used for cost-effective, nondestructive testing at nuclear power plants.
Purdue University, in West Lafayette, Ind.
Purdue University and Duke Energy have announced that they plan to jointly explore the feasibility of using advanced nuclear energy to meet the university’s long-term energy needs, “a move that may be unprecedented for a college campus.” A small modular reactor could meet the current and future needs for Purdue’s West Lafayette, Ind., campus, as well as provide excess power to the state’s electric grid, according to a joint press release.

Michigan State University’s Facility for Rare Isotope Beams (FRIB) officially opened yesterday with a ribbon-cutting ceremony attended by Energy Secretary Jennifer Granholm, elected officials, and guests who had supported the project during its planning and construction, including ANS Executive Director/Chief Executive Officer Craig Piercy. They were there to celebrate the completion—on time and within budget—of the world’s most powerful heavy-ion accelerator and the first accelerator-based Department of Energy Office of Science user facility located on a university campus.
