Chris Cosgrove, a senior business development manager at Technetics, shares insights into the advancements in new nuclear technologies and highlights the crucial role of sealing vendors in their optimization.

With nuclear energy being the largest source of carbon-free power, expanding its reach is essential for global carbon emission reduction. Small modular reactors (SMRs) are a promising development in this regard. These reactors, prefabricated in factories for on-site assembly, are significantly smaller in size compared to existing commercial reactors and are designed to be walk-away safe.

Within the realm of SMRs, Technetics offers valuable expertise in developing customized sealing hardware solutions. As Chris explains, a seal, along with its associated hardware, forms a sealing system, and early collaboration with Technetics during the development cycle ensures cost-effective, leak-tight sealing. Factors such as temperature, pressure, media being sealed, leak rate, and seating load are carefully considered to design the optimal sealing system.

Sealing systems for SMRs must meet stringent requirements, including high-temperature, high-pressure, and high-radiation environments. Technetics, renowned as the foremost expert amongst nuclear sealing vendors, specializes in reactor vessels, feedthroughs, pressurizers, piping, and even spent fuel pools, among other critical components.

Metal seals, one of Technetics’ specialties, offer numerous advantages over polymers in challenging conditions. Their engineers offer a wide range of configurations, including standard move, raised face flange, and more, ensuring high-performance sealing while maintaining cost-effectiveness. Metal seals are particularly suitable for joints where temperature or pressure exceeds the limits of elastomers like Viton or in high-radiation environments.

Technetics not only focuses on reliable performance but also understands the importance of minimizing radiation exposure to nuclear workers during maintenance operations. By delivering robust sealing solutions, they contribute to enhanced safety and efficiency in nuclear facilities.

Hi. I'm Chris Cosgrove, a senior business development manager with Technenics. I'm here to speak with you about new nuclear technologies. The largest source of carbon free energy is nuclear, and expanding that technology is a key way to lower carbon emissions worldwide. Small modular reactors, or SMRs, are much smaller in size than existing commercial reactors, and are prefabricated in factories for assembly on-site. Most are designed to be walk away safe. There are many potential applications within an SMR where Technetics can help develop a custom solution to optimize the sealing hardware. Remember, a seal along with the associated hardware comprise a sealing system. If you work with Technatics early in your development cycle, we can help ensure you get the most cost effective leak tight sealing we will consider temperature, pressure, media being sealed, leak rate, and seating load among a myriad of factors to help you design the best sealing system. Sealing for SMRs requires not only a very leak type design but must also perform in high temperature, high pressure, and high radiation environments. These could be light water, molten salt, or even fusion reactors. Technonetics is the world's foremost expert in sealing four nuclear applications, especially reactor vessels. We can help, with your reactor vessel and feed throughs, pressurizers, piping, even spent fuel pools just to name a few applications. We routinely manufacture metal, graphite, and elastomer seals for nuclear applications. But just looking at metal seals for a moment, Our engineers have many configurations to choose from, whether your sealing system includes a standard move, rays face flange, or most other configurations, Technatics can assist in designing a seal assembly that provides high ceiling performance, but is also cost effective. There are many locations where our metal seals might be appropriate in place of polymers. Really any joint where temperature or pressure exceeds the limits of say Viton or where high radiation might degrade elastomers. Our solutions are meant to not only perform without failure under those conditions, but we also understand the importance of lowering radiation dose to nuclear workers during maintenance overages. If you have any questions about sealing for any nuclear rated application, please contact us at technetics dot com. Thank you.

Power and utility deals hit a record $205 billion in the first half of 2026

Power and utility deals hit a record $205 billion in the first half of 2026

Power and utilities M&A hit a record $205 billion across 92 deals in the first half of 2026, Deloitte reports. NextEra Energy's $124 billion Dominion Energy merger led the way. PwC says buyers are paying for gas, grid and dispatchable assets that add capacity faster than new builds. Who pays for grid upgrades is now the open question for data centers and large loads.

  • 01Two megadeals, NextEra Energy's $124 billion merger with Dominion Energy and the $48 billion AES take-private, drove Deloitte's record $205 billion first-half total, according to Deloitte, so the headline figure says more about the largest players than about the 92-deal field as a whole.
  • 02PwC says buyers now favor assets with contracted offtake or direct exposure to large-load customers, alongside those with clear cost recovery, which makes contracted cash flows and who pays for grid upgrades questions a data center or plant operator should raise at its next utility meeting.
  • 03Where a jurisdiction assigns large-load costs (directly to data centers, through general rates, or through new contractual models) is becoming a valuation input for acquirers, so the tariff dockets being drafted now will shape both the power bill and who owns the utility.

NextEra Advances Duane Arnold Nuclear Restart With Federal Loan

NextEra Advances Duane Arnold Nuclear Restart With Federal Loan

NextEra Energy received a Department of Energy loan of up to $1.9 billion and Federal Energy Regulatory Commission approval to reconnect the shuttered Duane Arnold nuclear plant in Iowa to the grid. The company has already signed a 25-year electricity supply agreement with Google for the plant, which it aims to restart by early 2029.

  • 01NextEra closed a $1.9 billion DOE loan through the Office of Energy Dominance Financing to fund the Duane Arnold restart, targeting electricity production by early 2029.
  • 02Google committed to a 25-year power purchase agreement with Duane Arnold to support its cloud-computing and AI infrastructure in Iowa.
  • 03Duane Arnold is one of three shuttered U.S. nuclear plants restarting with federal financing, alongside Constellation Energy's Crane plant ($1 billion loan) and Holtec's Palisades plant ($1.52 billion loan).

India Order Could Free Up 15.7 GW of Renewable Grid Access

India Order Could Free Up 15.7 GW of Renewable Grid Access

India's Central Electricity Regulatory Commission ordered on July 11 that renewable developers surrender transmission rights or provide higher bank guarantees if their projects are not generating power, a change Reuters reported could free up roughly 15.7 gigawatts of grid connectivity. Reuters separately reported that coal still supplies about 70% of India's electricity generation as of an August 17 report.

  • 01CERC order requires renewable developers to either surrender transmission rights or post additional bank guarantees for non-generating projects.
  • 02Approximately 15.7 GW of grid connectivity held by awarded projects that are not generating power could be freed up; surrendered capacity would first go to existing applicants in the same substation cluster, with any remainder auctioned.
  • 03Developers and buyers evaluating projects in constrained substation clusters should verify current CERC connectivity status and guarantee backing, as auction-based allocation may alter cost and timing dynamics.
