Round Up: Deep Fission gets construction partner for reactor; DOE picks two companies for used fuel canister monitoring; Deep Isolation secures over 100 patents

By ExchangeMonitor

Deep Fission has partnered with Day & Zimmerman for the construction of Deep Fission’s underground Gravity reactor in Great Plains Industrial Park in Parsons, Kan.

According to Day & Zimmerman’s Tuesday press release, Day & Zimmerman will oversee the Deep Fission’s project’s pre-construction planning and perform the above-ground construction. The reactor being constructed in Kansas is Deep Fission’s reactor that was selected under the Department of Energy’s reactor pilot program

“Partnering with Day & Zimmermann will bring proven nuclear construction expertise and execution discipline to Deep Fission’s deployment,” Deep Fission’s Chief Operating Officer Mike Brasel said. “Their track record supports our aim to deliver a new model for low-carbon, reliable power that is simpler to build, inherently safe, and scalable to meet growing energy demand.”

 

The Department of Energy’s Center for Used Fuel Research has picked companies Guidewave and Sensible Photonics on Tuesday to move onto the final phase of a selection process to demonstrate technologies used to monitor spent fuel dry storage canisters.

DOE said in a press release that the selections are important to addressing a need regarding spent nuclear fuel storage. The agency went on to say that automated and continuous monitoring and inspection approaches could streamline “aging management activities and reduce operational burdens for used nuclear fuel management.”

After being selected, both companies will now move onto pre-demonstration testing. This will take place at DOE’s Idaho National Laboratory this summer. Results from the pre-testing will decide the final selection of a technology for a full scale demonstration, which will take place at San Onofre Nuclear Generating Station in California in 2027. 

 

Deep Isolation has been issued over 100 patents worldwide, the company announced recently. 

This achievement reflects Deep Isolation’s strategy to build an integrated intellectual property footprint that protects every stage of the nuclear waste disposal lifecycle,” Deep Isolation said in a May 26 press release.

The company continued,“Collectively, the patent portfolio is designed to support an end-to-end disposal ecosystem, including repository architecture, advanced methods for geologic site characterization, canister and packaging systems, emplacement and retrieval technologies, and closure and repository monitoring systems.”
