In the race to decarbonize and secure America’s energy future, nuclear power is once again in the spotlight. From advanced reactors to fusion breakthroughs, the promise of nuclear energy is clear.

The UK has confirmed that Wylfa on the island of Anglesey, North Wales, will host three Rolls-Royce small modular reactors (SMRs) that could deliver first power in the mid-2030s—launching a state-backed, fleet-based nuclear deployment through publicly owned entity Great British Energy–Nuclear (GBE-N). The UK government has framed the SMR project, which is underpinned by more […]

Keith Kotimko is the U.S. Decommissioning and Demolition Leader for WSP, a full-service solution provider that offers comprehensive facility decommissioning and demolition services. Kotimko provided POWER with insight into the process of permanently shutting down a power generation facility. He emphasized that decommissioning is a separate activity from demolition.

Westinghouse has partnered with Google Cloud to develop a custom AI-powered platform using specialized models from both Google and Westinghouse—itself a leader in AI for energy production—that helps optimize and accelerate reactor construction.

An energy research group said U.S. power generation capacity will be led by solar power in the short term, natural gas in the mid term, and nuclear power in the long term as coal-fired units continue to be retired.

Securing a reliable supply of electricity requires plenty of research to balance the risks and rewards of striking a deal.

The retirement of older thermal power generation facilities, driven by a transition to cleaner forms of energy, has increased in recent years as utilities and other power generators mothball plants that are uneconomic or simply no longer needed.

A Texas-based developer and operator of next-generation digital infrastructure and integrated power assets announced it has entered into a land option purchase agreement for a site in New Mexico that would feature a vast data center center campus. The plan announced November 6 calls for more than 2 GW of natural gas-fired generation capacity, and 5 GW or more of nuclear power, to energize the 3,500-acre site.

Process manufacturers and power producers are feeling the pressure of tight margins and increasing economic uncertainty. The data tools that engineers and plant operators have relied on for years are rapidly evolving, prompting many to consider how and when to migrate to a new data management platform that enables a more efficient and seamless integration […]

In this case study, Lamons helped a Montana refinery overcome a critical flange misalignment issue during the final stages of an FCC unit turnaround. Traditional methods and standard gaskets failed to resolve the problem, threatening costly delays and safety risks. Leveraging our engineering expertise and rapid response capabilities, Lamons designed and delivered a custom wedge […]
