The Department of Energy announced on Wednesday that the first large-scale treatment of radioactive and chemical waste from underground tanks at the Hanford Site near Richland, Wash., has begun with the start of operations of the Tank-Side Cesium Removal (TSCR) System.
The newly operational TSCR System removes radioactive cesium and solids from the tank waste. The treated waste will be fed directly to the nearby Waste Treatment and Immobilization Plant (WTP) for vitrification when the plant comes on line next year.

Bruce Power, General Fusion, and the Nuclear Innovation Institute have signed a memorandum of understanding to evaluate the potential deployment of a fusion power plant in Ontario, including in a region on the shores of Lake Huron comprising three counties—Bruce, Grey, and Huron—that has been dubbed the Clean Energy Frontier. Together the three organizations plan to build on existing clean energy technologies and expertise in the region and lead stakeholder and public outreach activities to raise awareness of the potential benefits of fusion energy.

Kite & Key Media, which produces short videos that provide context on an array of topical issues, has released an online video that sets the record straight on just what nuclear waste is and how its publicly perceived risks don’t match up with reality.

The government of Sweden announced on January 27 that it has issued a permit to the Swedish Nuclear Fuel and Waste Management Company (SKB) to build a deep geological repository for spent nuclear fuel at Forsmark in the municipality of Östhammar. The government also issued a permit to construct a spent fuel encapsulation plant in Oskarshamn, where the country’s inventory of spent fuel is currently being stored.

Alaska Gov. Mike Dunleavy (R.) introduced “An act relating to microreactors” (SB 177) in the Alaska state legislature on February 1 that would modify existing state law on nuclear energy by specifying that microreactors are not subject to certain nuclear reactor siting and permitting regulations in Alaska. The bill defines a microreactor as an advanced nuclear fission reactor that would be capable of generating no more than 50 MWe.

Natrium, a 345-MWe sodium fast reactor with a molten salt energy storage system, was developed by TerraPower and GE Hitachi Nuclear Energy. TerraPower is planning to build the first Natrium demonstration reactor by 2028 with 50-50 cost-shared funding of about $2 billion from the Department of Energy’s Advanced Reactor Demonstration Program. And for the requisite data and testing of reactor components to support that deployment, TerraPower is looking to Japan—a country with decades of experience developing sodium fast reactor designs and testing infrastructure.

Decades of fuel performance data coupled with advanced analytics and multi-processor computing have enabled the development of ‘novel’ modeling & simulation tools that allow nuclear fuel engineers to predict behavior across the entire fuel cycle. With this new capability nuclear fuel designers and fuel reload managers are better equipped to predict performance and reliability. These tools are fundamental to communicating highfidelity safety margin assessments with the regulator, and, when applied in the early stage of reactor design, can achieve optimum safety system functionality. At the apex of the fuel performance codes development pyramid sit a triad of codes: SI’s Pegasus, DOE’s Bison, and CEA’s Alcyone, which share the commonality of three-dimensional modeling and simulation of nuclear fuel performance. Unique among the capabilities represented by these codes is the ability to bridge the encoded-technology gap between the frontend and the backend of the fuel cycle to eliminate sources of uncertainties in spent fuel safety evaluations. This capability is a distinguishing feature of the Pegasus code.

A spokesperson for Georgia Power has confirmed that the projected in-service date for the new Vogtle-3 reactor remains the third quarter of 2022, according to an article published on January 27 on the Power magazine website. The in-service date for Vogtle-4 is targeted for the second quarter of 2023, the spokesperson said.

Savannah River Nuclear Solutions (SRNS), the Department of Energy’s management and operating contractor for the Savannah River Site in South Carolina, has reached an agreement with the state of South Carolina and federal environmental regulators on the final cleanup of a 25-mile-long stream corridor at the site that was radiologically contaminated as a result of operations during the Cold War.
The corridor consists of Par Pond, nine miles of canals adjacent to the pond, and a stream named Lower Three Runs. The stream begins near the center of the site, just above Par Pond, and winds its way southward across SRS.

Westinghouse Electric Company and Southern Nuclear have agreed to a plan to install four Westinghouse lead test assemblies in Vogtle-2, a 1,169-MWe pressurized water reactor located in Waynesboro, Ga. Four lead test assemblies containing uranium enriched up to 6 percent U-235 will be loaded in Vogtle-2 in 2023, marking the first time that fuel rods with uranium enriched above 5 percent U-235 are put in use in a U.S. commercial power reactor.

The Nuclear Regulatory Commission has issued a confirmatory order to Holtec Decommissioning International (HDI) following an alternative dispute resolution mediation session regarding security-related violations at the Oyster Creek nuclear power plant in Lacey Township, N.J. A subsidiary of Holtec International, HDI is decommissioning Oyster Creek, which permanently ceased operations in 2018.
