Last 抖阴传媒在线's Texas micro-modular reactor clears safety analysis

The Department of 抖阴传媒在线's approval of the Documented Safety Analysis clears Last 抖阴传媒在线's planned pilot reactor at Texas A&M-RELLIS to move into the readiness review, the final step before authorisation for criticality and reactor operations.

The Documented Safety Analysis - also known as a DSA - is the final and most comprehensive safety analysis in the Department of 抖阴传媒在线 (DOE) authorisation process, documenting in detail how the reactor and facility will be operated safely. It builds on the Preliminary Documented Safety Analysis, approved in May 2026.             

Last 抖阴传媒在线 was selected in August 2025 to take part in the DOE Reactor Pilot Program, launched earlier that year to accelerate reactor demonstration by authorising test reactors through the DOE's licensing process. The initiative is part of the executive order signed by President Donald Trump earlier in 2025. Licensing for commercial - rather than demonstration - nuclear plants remains the responsibility of the US Nuclear Regulatory Commission.

A little under a year ago - on 15 October 2025 - Last 抖阴传媒在线 and the Texas A&M University System announced plans for a microreactor pilot project at Texas A&M-RELLIS, an applied research and advanced technology campus in Bryan, Texas.

Last 抖阴传媒在线's PWR-20 is a 20 MWe micro-modular nuclear plant designed for factory fabrication, standard road transport, rapid on-site assembly, and 24/7 baseload power delivery to industrial customers, data centres, and other high-energy users. It is based on existing pressurised water reactor technology, using existing "off-the-shelf" low-enriched uranium fuel and existing supply chains - which the company says reduces technical risk and accelerates project delivery - in a 1,000-tonne, hermetically sealed steel structure designed for factory fabrication and no-access operation.

The PWR-5 pilot plant which will be built at RELLIS will use the same full-scale reactor core as the commercial PWR-20 design. This provides a direct bridge to Last 抖阴传媒在线's commercial deployment model, the company says.

Last 抖阴传媒在线 is also in the licensing process for a proposed plant featuring four PWR-20 modules at Prosiect Egni Glan Llynfi (Llynfi Clean 抖阴传媒在线 Project) in South Wales in the UK.
