     John Ketchum is the CEO of NextEra Energy. He says that “There are only a few nuclear plants that can be recommissioned in an economic way, and newer technologies like small modular reactors remain financially infeasible.”
     NextEra Energy continues to evaluate the possibility of reopening the Duane Arnold nuclear power plant in Iowa amid growing interest from data center companies Ketchum told investors Thursday during a third quarter earnings call.
     Ketchum said that Duane Arnold’s boiling water reactor could make it easier to restart and operate economically than other nuclear power plants. New nuclear technologies such as small modular reactors (SMRs) remain uneconomical.
     Ketchum added that nuclear power will likely supply just a fraction of the nine hundred gigawatts the U.S. needs to add by 2040 to keep up with demand.
     Despite the recent fervor among tech companies and investors about nuclear energy, Ketchum contended that renewables and storage will likely play a greater role in satisfying new energy demand for at least two decades to come.

     Ketchum said, “Nuclear will play a role, but there are some practical limitations. There are only a few nuclear plants that can be recommissioned in an economic way … But even with a one hundred success rate on those recommissionings, we would still only meet less than one percent of that [new] demand.”
     According to Jefferies Research Services, expert analysts had anticipated that NextEra might announce a deal to restart the six hundred megawatt Duane Arnold plant during the Thursday call despite potential challenges such as competition with robust regional wind resources, And although the expected announcement did not come, Ketchum said that the plant could be among the few that could be reopened and operate economically. NextEra is currently carrying out engineering assessments and speaking with local stakeholders about what it would take to reopen the plant.
     However, Ketchum said he was “not bullish” on the newer SMR technology. NextEra has an in-house team dedicated to SMRs but so far they have not drawn favorable conclusions about the SMR technology.
     Ketchum added that “A lot of [SMR equipment manufacturers] are very strained financially. There are only a handful that really have capitalization that could actually carry them through the next several years.”

     Ketchum also raised questions about the availability of nuclear fuel in the United States, and he noted that SMRs remain “very expensive” even as the cost of renewable energy sources continues to fall. “We’re prioritizing other generation resources at this time. Renewables are here for the long haul.”
     Ketchum also announced that NextEra had secured two framework agreements for the potential development of up to ten and a half gigawatt of renewables and storage to be built through 2030. Although NextEra executives said they were not yet able to identify which companies had countersigned the agreements, they described them as “Fortune 50” companies outside the tech industry.

     New power demand from data centers and tech hyperscalers amid an increasingly limited supply of new generation projects has increased pressure on other industries that are also looking to secure renewable energy, Ketchum said. “All ships are rising with the tide here because they may be facing higher power prices down the road.”
     NextEra reported a net income of one hundred and eight five billion, compared to one hundred two hundred and two billion in the third quarter of 2023.

     The Deep Atomic (DA) MK60 small modular reactor (SMR) design has been developed specifically to provide power and cooling to data centers.
     The MK60 is a light water SMR incorporating multiple passive safety systems. DA states that it is “compact, scalable, and built on a foundation of proven technology”. Each unit generates up to sixty megawatts and provides an additional sixty megawatts of cooling capacity through its “integrated data center-centric design approach”.
     DA is headquartered in Zurich, Switzerland. It says that the reactor is well-suited to various types of data centers, including those supporting traditional cloud services, cryptocurrency operations, and AI applications.
     William Theron is the founder of DA and CEO. He says, “Data centers are the backbone of digital innovation, but their massive energy needs have become the critical bottleneck blocking growth.”
     The MK60 is said to offer data center operators a scalable power solution that can be deployed in various locations, including areas with limited grid access. The reactor can be sited closer to urban areas due to its advanced safety features.
     Theron said, “It’s designed to be installed on-site at data centers, delivering reliable zero-carbon electricity and energy-efficient cooling, thereby significantly reducing carbon footprints, and helping data centers meet their increasingly stringent sustainability goals.”.
     Freddy Mondale is the Head of Engineering for DA. He noted that many areas were struggling to provide the amounts of power that new data centers require. “Our on-site reactors bypass these grid limitations, allowing data centers to be built in optimal locations without straining existing infrastructure.”
     Mondale says that a sixty megawatts reactor with additional sixty megawatts of cooling capacity “hits a sweet spot for data centers. It’s large enough to power significant compute infrastructure, yet small enough to allow for modular deployment and scaling”.
     Mondale added that “The MK60 can be deployed in multiples, allowing scalability from 60 MW up to over 1 GW to meet growing energy demands.”
     DA says it has already begun dialogues with regulators and potential customers as it moves forward with development. The company is seeking partnerships with data center operators and other investors who are “looking towards the future of sustainable digital infrastructure”.
     DA’s announcement of the MK60 follows several announcements by global tech giants related to nuclear energy.
     Microsoft announced last September that it had signed a twenty-year power purchase agreement with Constellation that will see the restart of Three Mile Island Unit 1. Google announced last week it had agreed to purchase energy from Kairos Power in a deal that would support the first commercial deployment of its fluoride salt-cooled high-temperature advanced SMRs by 2030 and aim for a fleet totaling five hundred megawatts of capacity by 2035. The following day, Amazon announced a series of agreements in which it will acquire a stake in advanced nuclear reactor developer X-energy and roll out its Xe-100 advanced SMR initially at a project in Washington State.
     Meanwhile, the head of Japanese cloud-based gaming services provider Ubitus KK has said that it is planning to build a new data center and is specifically looking at areas with nearby nuclear power plants to provide the required power.
