The township of Ignace in northwestern Ontario has indicated its willingness to host a potential deep geologic repository for Canada’s spent nuclear fuel. The town council voted unanimously on July 10 to pass a resolution indicating its willingness to participate in the Nuclear Waste Management Organization’s (NWMO's) process for selecting a repository site, making it the first Canadian community to officially move forward with the next phase of a site selection process that began in 2010.

Fast burst reactors were the first fast-spectrum research reactors to reach criticality by using only prompt neutrons with high-enriched uranium as fuel, creating a pulse for microseconds. Among many achievements, fast burst reactors were the first research reactors to demonstrate the ability of thermal expansion to terminate a pulse and to show how this could aid in reactor safety. In addition, fast burst reactors were pivotal in early fission studies including critical mass determination, criticality safety, the study of prompt and delayed neutrons, and much more.

Workers at the Department of Energy’s Hanford Site in Washington state recently unloaded a shipment of more than 10,000 gallons of sodium hydroxide delivered to the site’s Waste Treatment and Immobilization Plant (WTP). The liquid sodium hydroxide will be the first chemical fed into the plant’s melters to simulate Hanford’s radioactive and chemical tank waste.

Because of its hardness and its hardiness in the face of high temperatures, silicon carbide has been used for industrial purposes for decades. It has proven its worth as a key component of tiny TRISO fuel particles. But SiC has a weakness—in its pure form it is too brittle for use in structural components, such as 12-foot-long light water reactor fuel cladding tubes.
The radiochemistry laboratory, nicknamed the McCluskey Room, in the Hanford Site’s Plutonium Finishing Plant is where Harold McCluskey was contaminated in 1976, and where workers reentered more than 40 years later to clean up the mess left over from that accident. Health physics technician Clay Rowan is shown here taking radiological measurements near racks of glove boxes similar to one that exploded onto McCluskey. (Photo: DOE)
In 1976 at the Hanford Site in Washington state, a 64-year-old chemical operations technician named Harold McCluskey was working on columns filled with special exchange resins in a glove box at the Plutonium Finishing Plant.

The European Commission has issued a positive opinion on the technical and nuclear safety aspects of the construction of Units 3 and 4 at Cernavoda nuclear power plant in Romania.
Under the Euratom Treaty, nuclear project developers are required to notify the EC of planned investments and to demonstrate compliance with the highest nuclear safety standards.

Aalo reported last week that it has submitted a regulatory engagement plan to the Nuclear Regulatory Commission in “a huge step forward in getting regulatory approval for our Aalo-1 reactor.”

A statistical analysis of the factors behind the 2021–22 energy crisis in Europe is the subject of the article “Patterns and correlations in European electricity prices,” published in the journal Chaos: An Interdisciplinary Journal of Nonlinear Science. The study—conducted by researchers at the Institute for Energy and Climate Research at Forschungszentrum Jülich and the University of Cologne, both in Germany, and the Norwegian University of Life Sciences—describes reasons for the surge in energy prices that go beyond the commonly cited cause of Russia’s invasion of Ukraine.

While commissioning began earlier this year at Turkey’s first nuclear plant, new reports say the project is delayed by sanctions against Russia due to its military invasion of Ukraine.
