Josh Everett, a diver with UCC UK Ltd., enters bay No. 11 of Sellafield’s Pile Fuel Storage Pond in December 2022, the first time in over 60 years a diver has entered the legacy pond, used to store a variety of spent nuclear fuel types and wastes. During this commissioning nuclear dive, Everett’s underwater tasks included emergency diver extraction trial confirmation, radiation monitoring system verification, and radiation contact meter commissioning.

The last time a human entered the Pile Fuel Storage Pond at the Sellafield nuclear site in Cumbria, England, was in 1958, when records show a maintenance operator and health physics monitor carried out a dive into the newly constructed pond to repair a broken winch. At least that was true until December 2022, when Josh Everett, a diver from the U.K. specialist nuclear diving team Underwater Construction Corporation (UCC) UK Ltd., became the first person in more than 60 years to work in one of the most unique workplaces in the world.

Last year, the U.S. Geological Survey (USGS) released its 2022 list of 50 minerals that are essential to the function of our society, especially the economy and national security. Whether it’s indium for LCD screens and aircraft wind shielding, cobalt for iPhones, uranium for nuclear reactors and munitions, rare earth elements for wind turbine magnets, lithium for rechargeable batteries, or tantalum for electronic components, if we do not have an ample supply, bad things will happen.
Next Generation MG Control Power Cabinets Installed
Westinghouse Parts Business (WPB) is proud of the first next generation Motor Generator (MG) Set System fully operational at Palo Verde Generating Station. The team completed a first-of-a-kind (FOAK) implementation and installation at the power plant operated by Arizona Public Service (APS), including the next generation MG Control Power Cabinets and new MG Sets. Additionally, Westinghouse installed the new ARCH (Advanced Rod Control Hybrid) system. These systems were installed in a single outage providing additional synergies and cost savings to operations.
The Shippingport Atomic Power Station in Shippingport, Pa., the first full-scale nuclear power generating station in the United States, began operating in 1957.
Serving as the world’s first scalable nuclear power plant, Shippingport Atomic Power Station led the way for today’s nuclear generation fleet. Shippingport was centrally located roughly 25 miles from Pittsburgh, Pa., to provide electrical generation for many end-users. Shippingport also served as an experimental reactor that allowed engineers and designers the ability to test different core designs, and as such, the site housed additional testing equipment otherwise not commonly seen. The primary goal of Shippingport was always to generate electricity; however, its ability to function as an experimental reactor served utilities in further development of scalable nuclear generation.

Nuclear power is the single largest source of clean energy in the United States, but how can the value of “clean” be measured? Two recent reports by researchers at the Massachusetts Institute of Technology and Pacific Northwest National Laboratory, respectively, measured the clean energy benefits of nuclear energy in different ways: the benefits to human health from the air pollution avoided and the future economic value of avoided carbon emissions.

Under the Radioisotope Power Systems Program, NASA and the Department of Energy have been advancing a novel radioisotope power system (RPS) based on dynamic energy conversion. This approach will manifest a dynamic RPS (DRPS) option with a conversion efficiency at least three times greater than a thermoelectric-based RPS. Significant progress has recently been made toward this end. A one-year system design phase has been completed by NASA industry partner Aerojet Rocketdyne, which resulted in a DRPS with power of 300 watts-electric (We) with convertor-level redundancy. In-house technology development at the NASA Glenn Research Center (GRC) has demonstrated the conversion devices in relevant environments and has shown all requirements can be met. Progress has also been made on the control electronics necessary for dynamic energy conversion. Flight-like controllers were recently upgraded and achieved an 11-percentage-point increase in efficiency. Control architectures have been developed to handle the multiconvertor arrangements in the latest DRPS design. A system-level DRPS testbed is currently being assembled that will experimentally demonstrate the DRPS concept being pursued.

Dow and X-energy announced today that they have signed a joint development agreement (JDA) to demonstrate the first grid-scale advanced nuclear reactor at an industrial site in North America within a decade. As part of the agreement, Dow is now a subawardee under X-energy’s Advanced Reactor Demonstration Program (ARDP) Cooperative Agreement with the Department of Energy.
Comments due April 14 for draft report aimed at revisiting EPA regulations
LA GRANGE PARK, Illinois – Today, the American Nuclear Society (ANS) released draft recommendations on updating public health and safety standards for the permanent disposal of commercial used nuclear fuel and high-level radioactive waste at future geological repository projects in the United States. The draft report provides a recommended framework for revisiting U.S. Environmental Protection Agency (EPA) geologic repository standards.
