The International Atomic Energy Agency has launched a five-year coordinated research project (CRP) to strengthen plant health preparedness using nuclear and related technologies.

Wheat blast, potato late blight, potato bacterial wilt, and cassava witches broom disease can spread quickly across large areas of land, leading to severe yield losses in key crops for food security. Global trade and climate change have increased the likelihood of rapid, transboundary spread.

Inconsistent terminology: An RIPB stumbling block

April 29, 2026, 1:09PMANS News

The American Nuclear Society’s Risk-informed, Performance-based Principles and Policy Committee (RP3C) held another presentation in its monthly Community of Practice (CoP) series. Former RP3C chair N. Prasad Kadambi opened the June 27 meeting with brief introductory remarks about the RP3C and the recent incorporation of risk-informed, performance-based (RIPB) design principles in the Nuclear Regulatory Commission’s Part 53 framework. He then welcomed this month’s speaker: Lyndsey Fyffe, a nuclear safety engineer with Strategic Management Solutions, who presented “RIPB Terminology Across the Nuclear Industry.”

Claiming the Department of Energy is backing away from commitments made in a 2023 settlement agreement with the state, the New Mexico Environment Department (NMED) is proposing revisions to the Waste Isolation Pilot Plant operating permit. The revisions would prioritize the disposal of waste generated in New Mexico at WIPP, including legacy radioactive waste from Los Alamos National Laboratory.

On Sunday, May 17, in Baltimore, Md., there will be an open house on the NS Savannah to commemorate National Maritime Day. The Savannah acted as a passenger and cargo ship from 1962 to 1970, serving as a floating ambassador for President Eisenhower’s Atoms for Peace program and, more broadly, for the safe and peaceful uses of nuclear power.

DOE selects first companies for nuclear launch pad

April 28, 2026, 2:56PMNuclear News

The Department of Energy’s Office of Nuclear Energy and the National Reactor Innovation Center have announced their first selections for the Nuclear Energy Launch Pad: three companies developing microreactors and one developing fuel supply.

The four companies—Deployable Energy, General Matter, NuCube Energy, and Radiant Industries—were selected from the initial pool of Reactor Pilot Program and Fuel Line Pilot Program applicants, the two precursor programs to the launch pad.

The Nuclear Regulatory Commission has renewed the Robinson nuclear power plant’s operating license in record time, the agency announced last week.

The subsequent license renewal process for the Hartsville, S.C., facility was completed within 12 months, according to the NRC. The process has typically taken 18 months. This was the first license renewal review conducted under the directive of Executive Order 14300 to streamline processes like renewing operating licenses.

Access anywhere, anytime: Nuclear power, Ice Camp, and Rickover’s enduring standard of excellence

As U.S. Navy submarines surface through Arctic ice during Ice Camp 2026, they demonstrate more than operational proficiency in one of the harshest environments on Earth. They reaffirm a technological truth first proven in August 1958, when the USS Nautilus completed its submerged transit of the North Pole: nuclear power enables access anywhere, anytime.

The Arctic is unforgiving, with vast distances, extreme cold, shifting ice, and no logistical infrastructure. Conventional propulsion is constrained by fuel, air, and endurance. Nuclear propulsion removes those constraints. Only a nuclear-powered submarine can operate anywhere in the world’s oceans, including under the polar ice, undetected and at maximum capability for extended periods. Nuclear power provides sustained high speed and the endurance to reposition across the globe without refueling.

Three research groups are reporting fusion-related developments, including ongoing work toward spin-polarized fusion, a new plasma diagnostic tool heading to the National Ignition Facility, and a materials science project that could impact the design of inertial confinement fusion fuel targets.

Rolls-Royce–CEZ SMR project at Temelín moves forward

April 27, 2026, 1:12PMNuclear News

A newly signed contract between U.K.-based Rolls-Royce SMR and the ČEZ Group in the Czech Republic will allow for design work to begin on the planned small modular reactors at the Temelín nuclear power plant site in the Czech Republic. The companies, which hope to deploy as much as 3 gigawatts of new nuclear capacity in the country, signed an early works contract that will see them begin preparing for consents, permitting, and licensing and continuing preliminary infrastructure activities as they develop a site application for the SMRs.

NRC introduces microreactor regulatory framework

April 27, 2026, 9:28AMNuclear News

The Nuclear Regulatory Commission has released a new licensing framework for microreactors and similar reactor designs that may provide a more suitable pathway for applicants with simpler technologies.

The proposed rule—known as Part 57—is the latest to come out of the NRC’s rules review and overhaul stemming from the ADVANCE Act and 2025 nuclear-related executive orders. It is also the latest framework developed for advanced reactor designs shifting away from light water reactor technology, such as the Part 53 rule finalized in March.

Sunday, April 26, at 1:23 a.m. local time will mark 40 years since the most severe nuclear accident in history: the meltdown of Unit 4 at the Chernobyl nuclear power plant in Ukraine, then part of the Soviet Union.

In the ensuing four decades, countless books, documentaries, articles, and conference sessions have examined Chernobyl’s history and impact from various angles. There is a similar abundance of outlooks in the archives of Nuclear News, where hundreds of scientists, advocates, critics, and politicians have shared their thoughts on Chernobyl over the years. Today, we will take a look at some highlights from the pages of NN to see how the story of Chernobyl evolved over the decades.
