Here is info. about the NO KINGS/NO NUKES rallies from the anti-nuke Clamshell Alliance:
 
Clamshell Alliance is calling on all activists to carry NO KINGS! NO NUKES! signs on March 28th.
 
March 28 is the next No Kings Day. Let’s bring this message to millions of people: Remember Three Mile Island. Deadly radiation and mass evacuations from the March 28, 1979, nuclear power meltdown in Pennsylvania alerted the US and the world to just some of the lethal consequences of nuclear energy. Now federal and state governments across the US (from Massachusetts to Kansas) and the oligarchs and authoritarians we resist are forcing new nuclear power on the American public.
 
This article: "On March 28 Let’s Say “No Kings” and “No Nukes” by Karl Grossman & Harvey Wasserman explains how the resistance to the current push for nuclear power is connected to NO KINGS.
 
Let’s all carry signs to raise up this issue:
NO KINGS! NO NUKES!
Remember the 3/28/79 MELTDOWN at Three Mile Island!
DEMOCRACY, NO NUKES, SAFE ENERGY
NO NUKES! REMEMBER TMI MELTDOWN 3/28/79.
DEMOCRACY NEEDS CLEAN ENERGY. NO NUKES!
 
CLIMATE Sí! SAFE ENERGY Sí! NO NUKES!
Please pass this on to your local (and beyond) contacts (including Indivisibles) organizing 3/28 No Kings.

The importance of medical isotopes is often invoked to justify the existence of nuclear power reactors.
 
Medical isotopes are radioactive materials that are used for diagnostic and therapeutic purposes. But despite nuclear industry hype, the fact is that modern medicine has never depended on nuclear power reactors. Any isotopes (radioactive materials) that are considered medically useful have been either extracted from nature or have been produced in “particle accelerators” such as cyclotrons, or in research reactors that do not produce electricity. 
 
In addition, medical procedures that do not involve radioactivity at all are increasingly preferred – they are often less costly and less hazardous, and do not leave a legacy of radioactive waste behind.

Lancaster County to get Pa. funds for Three Mile Island emergency planning

With the Three Mile Island Unit 1 nuclear reactor slated to reopen next year, Lancaster County is set to receive additional state funding for nuclear emergency response planning.

The Board of Commissioners on Wednesday is set to approve a $36,500 grant from the Pennsylvania Emergency Management Agency to help cover the salary of a response manager who is updating the county’s response plans to a nuclear disaster for the Lancaster County Emergency Management Division.

The Lancaster County Salary Board approved the creation of the radiological planner position in October.

 

The plans include “everything from how we communicate and notify people, as well as to how we’re going to evacuate people, so we have somebody specifically focused on rebuilding all of that from the ground up,” Department of Public Safety Director Brian Pasquale said.

In 2024, Constellation Energy announced plans to reopen Unit 1 of the Three Mile Island facility and gave it a new name — Crane Clean Energy Center. The sole customer for the facility’s 835 megawatts of expected output is Microsoft, which has signed a 20-year agreement to buy power for its growing network of data centers.

In December, Constellation Chief Executive Joe Dominguez said he expects the facility to be operational in the summer of 2027, a year earlier than initially planned. He said its opening will come at a pivotal time to “power this important revolution in AI.”

Unit 2 has remained closed since its partial meltdown in 1979, and its owner, Energy Solutions, in the process of decommissioning the reactor.

Unit 1 remained in operation until 2019, when Constellation closed it, citing cost concerns.

On Monday, Lancaster County’s emergency preparedness team held its first tabletop exercise related to the reopening of the Three Mile Island site, Pasquale said at Tuesday’s commissioners work session.

Tabletop exercises are a planning tool to game out specific real-world scenarios to put plans and procedures to the test in a low-stakes environment.

The PEMA dollars for the county comes from the Radiological Emergency Response Program, funded by fees assessed to nuclear operators.

An Amazon-backed small modular nuclear reactor company is filing for an initial public offering amid rising investor interest in nuclear energy. X-energy submitted a draft registration statement to the Securities and Exchange Commission on Friday, putting it on track to go public sometime in the early summer. The IPO would be the latest for developers of small modular nuclear reactors, which have been touted as a potential solution for rapid electricity demand growth caused largely by data centres, but also the electrification of cars and household appliances. According to data from BloombergNEF, US data centre power demand is set to climb from 34.7 gigawatts in 2024 to 106GW by 2035. X-energy is building an SMR that uses helium as a coolant instead of water, the industry standard. Supplies of helium have been severely disrupted by the effective closure of the Strait of Hormuz amid the Iran war, pushing up commercial prices. “Spot helium prices could spike by 50 per cent to 200 per cent in severe shortage scenarios,” according to Fitch analysts. Amazon backed the company in October 2024, anchoring a $400mn fundraising round along with Citadel’s Ken Griffin. The ecommerce giant took two seats on the company’s board. In November X-energy completed a $700mn fundraising round led by Jane Street, ARK Invest, Galvanize, Hood River Capital Management, Point 72, Reaves Asset Management and XTX Ventures. In addition to Amazon, it has secured contracts with FTSE 100-listed Centrica and Dow. While X-energy has not received full approval from the Nuclear Regulatory Commission to build its reactor, in February the agency licensed the company to make nuclear fuel for advanced reactors at a facility in Oak Ridge, Tennessee. X-energy declined to state how much it is seeking to raise, or how its shares would be priced. JPMorgan, Morgan Stanley, Jefferies and Moelis and Company are acting as the lead bookrunners. X-energy would be the fourth publicly traded SMR company, following Nano Nuclear, NuScale Energy and Sam Altman-backed Oklo. Oklo’s stock price has gained 94 per cent over the past year. But Nano and NuScale have lost ground, falling 32 and 27 per cent respectively. Recommended The Big Read The cost of America’s nuclear revival The filing comes as Wall Street investment bankers are gearing up for a series of potentially huge listings later this year. Elon Musk’s rocket group SpaceX and AI start-ups Anthropic and OpenAI have all indicated plans to go public at some point in 2026. Each of the three deals is expected to raise tens of billions of dollars in proceeds, potentially outstripping the total haul from about 200 US IPOs in 2025. Market volatility triggered by the war in Iran could yet scupper bankers’ pipeline, however, just as the economic turmoil sparked by President Donald Trump’s so-called liberation day tariffs last April put several large US tech listings on pause.

I can offer you a special discount of 30% off for members of this list. Use NUCLEAR30 to receive it.
 
The goal with this book is for you to purchase to give to someone else -- a relative, friend, colleague who may be on the fence or even pro-nuclear. 
 
It's hopefully a comprehensive indictment of the many reasons to oppose nuclear power (and nuclear weapons), so by the time a reader is finished, he/she will have been convinced by one argument or another -- or all of them put together!
 
If you would like to do an in--person event or webinar with me about the book, please get in touch.
 
All the best,
Linda

Community Kayak to Protest Savannah River Site Plutonium Pit Production – March 28
 
AUGUSTA, GA (March 19, 2026) — A coalition of local groups are hosting a day-long “Paddle and Boogie to Stop the Bomb” event on the Augusta Canal next to the Savannah River to advocate against the production of plutonium pits for nuclear weapons and to share information about the radiation contamination risks of the Department of Energy’s (DOE) Savannah River Site (SRS) ahead of upcoming public hearing and comment periods.
 
Participants will paddle 5.5 miles in the morning from Savannah Rapids Park in Martinez to the Mill Village Trailhead in Augusta, where there will be an afternoon gathering with live music, educational information and more fun activities.
 
Background:
SRS is a 310-square-mile site near Aiken, SC, that was produced plutonium and tritium for use in nuclear weapons from the 1950s to the 1990s. The plutonium was shipped to Rocky Flats, CO, where it was turned into plutonium pits. Rocky Flats was shut down and designated as a Superfund site in 1989 after investigations found significant radioactive environmental contamination.
 
With little public discussion or notice, the Department of Energy (DOE) determined it would produce new plutonium pits at SRS. After a lawsuit, a 2024 court ruling found that DOE violated the law under the National Environmental Policy Act by failing to complete a new and comprehensive programmatic environmental impact study that fully considers the effects of producing plutonium pits for nuclear weapons at SRS and Los Alamos Nuclear Laboratory.
 
DOE and the National Nuclear Security Administration (NNSA, semi-autonomous agency within DOE) are due to release the required programmatic environmental impact study in the coming weeks. There will be a 90-day public comment period, and a series of five court-mandated public hearings, including one in Aiken, SC. The previous PEIS for the plutonium program, in 2008, provoked more than 100,000 public comments.
 
Event Details:
Paddlers will meet by Savannah Rapids Kayak Rental (Savannah Rapids Park, 7 Savannah Rapids Trail, Martinez) at 9 a.m. ET, and depart by 10 a.m. for Mill Village Trailhead on the Augusta Canal (109 Eve St., Augusta), with live solar-powered music headlined by roots rock reggae band Natti Love Joys and fun educational events beginning at 1 p.m. Bring your own kayak or rent one (mention Paddle and Boogie for a discounted rental). There will be a shuttle back to the starting point for paddlers.
 
 
Contact:
Reporters with questions or an interest in attending should contact Joanne Sweeney, president of Nuclear Watch South, at savannahriverpilgrim@gmail.com or 706-809-1639.
