NRC issues subsequent license renewalsNuclear NewsPower & OperationsMarch 9, 2020, 10:18AM|Nuclear News StaffExelon Generation’s Peach Bottom-2 and -3, located in Delta, Pa., have joined Florida Power & Light Company’s Turkey Point-3 and -4 as the only U.S. nuclear reactors licensed to operate for a total of 80 years.On March 5, the Nuclear Regulatory Commission issued subsequent license renewals to Exelon for the Peach Bottom boiling water reactors, with expiration dates of August 8, 2053, for Unit 2, and July 2, 2054, for Unit 3. The FPL units received their first--in--the-nation SLRs last December (NN, Jan. 2020, p. 15).“We are pleased with the NRC’s decision to grant a subsequent license renewal for Peach Bottom Units 2 and 3,” said Bryan Hanson, Exelon Nuclear’s chief nuclear officer, in a statement. “This plant is well suited to continue running safely, reliably, and efficiently, given the extensive upgrades accomplished over the past seven years.”According to the utility, significant investments have been made recently in new equipment and technologies at Peach Bottom, leading to an increase in generation capacity of approximately 12 percent. The plant’s high- and low-pressure turbines, for instance, as well as the steam dryers, main generators, and main power transformers, have been replaced or upgraded.“The ability to operate Peach Bottom for another 20 years is good news for the environment, our employees, and the community,” Hanson said. “However, nuclear plants must remain financially viable to continue to operate. It’s critical that we continue to pursue policy reforms that value the environmental, economic, and reliability benefits that zero--carbon nuclear energy provides.”Exelon estimates that if Peach Bottom continues to generate electricity through 2054, more than 536 million tons of carbon will be prevented from entering the atmosphere—the equivalent of removing 3.3 million cars from the roads every year for 34 years.The SLR application for Peach Bottom was submitted in July 2018 (NN, Sept. 2018, p. 20), and in June of the following year, an Atomic Safety and Licensing Board terminated the adjudicatory proceeding regarding the application brought by the antinuclear group Beyond Nuclear.Tags:exelonlicense renewalpeach bottomShare:LinkedInTwitterFacebook
Exelon touts reliability of Illinois nuclear plantsThe Byron nuclear plant is scheduled to close this September. Photo: ExelonAmid all the talk of last week’s winter storm and the resultant grid debacle in Texas, Exelon on Monday issued a press release informing customers of just how reliably its Illinois nuclear power plants have been operating this winter.The release might also be seen as a message to state lawmakers, who have yet to produce any legislation to aid the utility’s financially challenged nuclear facilities—of which two, Byron and Dresden, have been slated for retirement later this year, given the (so-far) absence of such legislation.Go to Article
Exelon Generation’s workforce development and knowledge transfer strategyStudents display items they received at a STEM workshop sponsored by Exelon. Photo: Exelon. The landscape of Exelon Generation’s nuclear business has continued to evolve—even before the complications of a pandemic—but people will always remain the core focus. Our employees and our future employee pipelines are changing almost as fast as technology, which is why the development of the workforce, both present and future, along with the transfer of knowledge across all departments and levels of the organization, must remain adaptable and advance as well.Go to Article
NRC accepts Point Beach SLR applicationThe Nuclear Regulatory Commission has accepted for review NextEra Energy’s subsequent license renewal (SLR) application for its Point Beach reactors, making them the fifth and sixth units currently under consideration for a second 20-year license renewal. (SLR applications for Dominion Energy’s North Anna-1 and -2 and Surry-1 and -2 are also being reviewed, while SLR approval has been granted for Exelon’s Peach Bottom and NextEra’s Turkey Point units.)NextEra submitted the SLR application in November of last year—the first such application involving a Midwestern nuclear plant. The NRC approved the plant’s initial license renewal in December 2005, allowing Unit 1 to operate through October 5, 2030, and Unit 2 through March 8, 2033.Go to Article
NRC agrees to review Westinghouse ATF topical reportWestinghouse last week announced via blog post that a topical report on its Advanced Doped Pellet Technology (ADOPT) fuel has been accepted for review by the Nuclear Regulatory Commission, calling the decision a “major achievement for the advanced fuel portfolio Westinghouse is developing as part of our EnCore fuel program.”The company submitted the report in May of last year, requesting approval by February 2022. According to Westinghouse, a draft safety evaluation from the agency is expected this summer.Go to Article
Fuel innovation: Powering nuclear modernizationToday’s U.S. commercial nuclear power plants are fueled with uranium dioxide pressed into cylindrical ceramic pellets—and have been for decades. These pellets are stacked inside long fuel rods made of a zirconium alloy cladding. Innovation in nuclear fuel, however, can improve safety, reduce operating costs, and further enable the development of a new generation of non-light-water reactors.Go to Article
EIA: Nuclear, coal will account for majority of U.S. generating capacity retirements in 2021According to the U.S. Energy Information Administration’s latest inventory of electric generators, 9.1 gigawatts (GW) of electric generating capacity is scheduled to retire in 2021.In total, it appears that 30 plants (nuclear, coal, petroleum, and others) will be retired in 2021. Five nuclear reactors are included in the closure list—Indian Point-3, Byron (two units at the plant), and Dresden (two units at the plant). Those three plants produce 5.1 GW of power, accounting for more than half of the total capacity expected to be retired.Go to Article
Searching for lost revenue from shut-down nuclear plants, NY law allows towns to assess waste storageIndian Point nuclear power plant. Photo: Entergy NuclearCommunities across the United States where nuclear power plants have been shut down face huge gaps in tax revenues, sometimes in the tens of millions of dollars. States such as New Jersey, Illinois, Wisconsin, and California are watching events in New York now that Gov. Andrew Cuomo has signed a new law that says cities can “assess the economic value of storing waste” on sites where nuclear plants once operated, as reported by Bloomberg.Go to Article

Exelon CEO urges Illinois legislators to save nuclear plantsCraneChristopher Crane, president and chief executive officer of Exelon, wrote in a Chicago Sun-Times op-ed, “The failure of national energy markets to support clean energy will soon force the premature retirement of two of [Illinois’s] six zero-carbon nuclear plants, putting thousands of people out of work, raising energy costs, and taking us decades backward in the fight against climate change."Crane urged Illinois policymakers to act quickly, as they face critical decisions about the future of energy that will affect the state’s environment, the economy, and the health of every family for years to come.Go to Article
Game-playing AI technique may lead to cheaper nuclear energyIn this AI-designed layout for a boiling water reactor, fuel rods are ideally positioned around two fixed water rods to burn more efficiently. MIT researchers ran the equivalent of 36,000 simulations to find the optimal configurations. Colors correspond to varying amounts of uranium and gadolinium oxide in each rod. Image: Majdi Radaideh/MITResearchers at the Massachusetts Institute of Technology and Exelon show that by turning the nuclear fuel assembly design process into a game, an artificial intelligence system can be trained to generate dozens of optimal configurations that can make each fuel rod last about 5 percent longer, saving a typical power plant an estimated $3 million a year, the researchers report.The AI system can also find optimal solutions faster than a human and can quickly modify designs in a safe, simulated environment. The results appear in the journal Nuclear Engineering and Design.Go to Article
