ANS recently hosted a Supplier Showcase webinar, “Digital Tools for Power Uprates: Using DVR and PEPSE to Enhance MUR and Performance Studies,” with a timely topic—power uprates—on the agenda.

The American Nuclear Society is hosting a new Supplier Showcase webinar, “Digital Tools for Power Uprates: Using DVR and PEPSE to Enhance MUR and Performance Studies,” on January 27 from 2:00 p.m. to 3:00 p.m. (EST).

The webinar is free for all viewers and requires registration.

TerraPower has continued to make aggressive progress in several areas for its Natrium Reactor Demonstration Project since the beginning of the year. Natrium is an advanced 345-MWe reactor that has liquid sodium as a coolant, improved fuel utilization, enhanced safety features, and an integrated energy storage system, allowing for a brief power output boost to 500 MWe if needed for grid resiliency. The company broke ground for its first Natrium plant in 2024 near a retiring coal facility in Kemmerer, Wyo.

North Carolina-based Curtiss-Wright has entered into an agreement to acquire Ultra Energy, a subsidiary of the U.K.-headquartered Ultra Electronics Holdings. Ultra Energy is a designer and manufacturer of reactor protection systems, neutron monitoring systems, radiation monitoring systems, and temperature and pressure sensors. The $200 million deal is expected to close this year in the third quarter, subject to U.K. regulatory approval.

Advanced nuclear technology firm TerraPower announced today the selection of four suppliers to support its Natrium reactor demonstration project, in development near a retiring coal plant in Kemmerer, Wyo.

Mobile unmanned systems, also known as MUS, encompass a range of robotic devices, including drones, ground vehicles, crawlers, and submersibles. They are used for a wide range of industrial and defense applications to automate operations and assist humans or completely remove human workers from hazardous conditions. Robotics are ubiquitous in industrial manufacturing. Military robots are routinely employed in combat support applications, such as reconnaissance, inspection, explosive ordnance disposal, and transportation. Drones are used in many industries for security and monitoring, to conduct aerial inspections or surveys, and to capture digital twins. Wind and solar farms use MUS technologies for day-to-day operations and maintenance.

Curtiss-Wright Corporation and small modular reactor developer X-energy have announced the signing of a preferred strategic supplier agreement to advance the design and deployment of the latter’s Xe-100 SMR.

The 26th Annual Nuclear Generator and Supplier Executive Summit, hosted by Utilities Service Alliance (USA), was held at the Coeur d’Alene Golf and Spa Resort in Idaho from June 28 through July 1. About 375 attendees were present for this year’s meeting, themed “Nuclear’s Next Wave” which featured presentations and discussions on emerging nuclear technologies and designs, as well as an integrated tradeshow with about 50 industry suppliers exhibiting products, services, and ideas.

Here is a recap of industry happenings over the course of the past month:

ADVANCED REACTOR MARKETPLACE

Ukraine’s Energoatom signs deals for nuclear power exploration and deployment

Energoatom, the state-owned nuclear utility of Ukraine, and Westinghouse Electric Company have signed an agreement to bring Westinghouse AP1000 reactors to multiple sites in Ukraine. The signing took place at the U.S. Department of Energy headquarters in Washington, D.C., and was witnessed by Ukraine’s president Volodymyr Zelensky, U.S. energy secretary Jennifer Granholm, and Ukraine’s energy minister German Galushchenko.

In addition, Energoatom signed a memorandum of understanding with NuScale Power to explore small modular reactor deployment in Ukraine. Under the MOU, NuScale will support Energoatom’s examination of NuScale’s SMR technology, including a feasibility study for proposed project sites and the development of a project timeline and deliverables, cost studies, technical reviews, licensing and permitting activities, and project-specific engineering studies and design work.

At first glance, the Advanced Test Reactor Critical (ATRC) Facility has very little in common with a full-size 800- or 1,000-MW nuclear power reactor. The similarities are there, however, as are the lessons to be learned from efforts to modernize the instrumentation and control systems that make them valuable assets, far beyond what their designers had envisioned.

One of four research and test reactors at Idaho National Laboratory, the ATRC is a low-power critical facility that directly supports the operations of INL’s 250-MW Advanced Test Reactor (ATR). Located in the same building, the ATR and the ATRC share the canal used for storing fuel and experiment assemblies between operating cycles.
