The Trump admin is proposing a 7% cut to @NNSANews nonproliferation programs—diverting funds to likely unnecessary nuclear weapons work. Doesn't sound like much, until you see the long term trend...

BREAKING NEWS: Michelle Sampson of @NRCgov just said they have heard from a potential advanced reactor applicant who wants to use bomb-usable HIGHLY ENRICHED URANIUM in their design. This is beyond the pale.

There have now been at least two successful attacks like this related to Kudankulam. reuters.com/world/india/fi…

TEPCO's Fukushima Daiichi & Daini plants now join Kashiwazaki-Kariwa on the list of sites where sensitive antiterrorism info wasn't kept in controlled storage as required. Physical security only works if information security keeps pace. japantoday.com/category/natio…

One of the most significant achievements in reducing nuclear terrorism risks over the past two decades is something that rarely makes headlines: the complex, painstaking work of eliminating weapons-usable nuclear material from countries that once held it. nti.org/risky-business…

The IAEA team based at the Zaporizhzhya Nuclear Power Plant (ZNPP) this week confirmed significant damage to a fire station in the nearby city of Enerhodar that plays an important role in supporting the plant’s emergency response capability, Director General @rafaelmgrossi said today: iaea.org/newscenter/pre…

SCOTUS overruled decades of precedent shielding independent agency leaders from at-will firing. Implications for nuclear safety & security are profound: regulation that should rest on rigorous technical analysis now risks swinging w/ every political cycle. washingtonpost.com/politics/2026/…

The United States will regret trying to expand nuclear energy while simultaneously weakening safety and security.

News flash! The @NRCgov reorganization has taken effect today. The Office of Nuclear Security and Incident Response is no more. nrc.gov/docs/ML2132/ML…

The IAEA has been informed of a serious incident that occurred during today’s de-mining phase of the agreed localized ceasefire near the Zaporizhzhya NPP, in which some Russian military personnel were injured. While the incident is currently being investigated, the Ukrainian side has informed the IAEA that it remains committed to the IAEA-brokered ceasefire that it and Russia agreed to after weeks of complex negotiations. IAEA DG @rafaelmgrossi calls for maximum military restraint and full adherence to the ceasefire so that the power line repairs can proceed as planned in coming days, adding that they are crucial for efforts to prevent a nuclear accident at the ZNPP. The urgency and necessity of repairing the ZNPP’s main 750 kilovolt (kV) power line was underscored by another loss of off-site power event at the plant today, the 18th since the war started. The ZNPP once again had to rely on emergency diesel generators after its sole remaining power line - the 330 kV Ferosplavna - was disconnected due to reported attacks on two electrical substations located on the other side of the Dnipro River. With the 750 kV line disconnected for more than two months, the ZNPP has been relying on the 330 kV line, making it extremely vulnerable to conflict-related grid disruptions. The 330 kV line has been disconnected repeatedly in recent weeks, including today. The restoration of the 750 kV Dniprovska line would be an important positive step for nuclear safety, which is in everybody’s vital interest, DG Grossi says.

The IAEA has been informed by the Zaporizhzhya Nuclear Power Plant (ZNPP) that the nearby Zaporizhzhya Thermal Power Plant (ZTPP) - whose switchyard helps deliver electricity to the ZNPP - has been under heavy attack this morning. The IAEA team at the ZNPP saw light smoke coming from the direction of the ZTPP and heard the sound of military activity. The incident raises serious concern about the ZNPP’s sole remaining power line, which in recent weeks has been disconnected several times, leaving the plant entirely reliant on emergency diesel generators for the electricity it needs to cool its six reactors and avoid the threat of a nuclear accident. For now, the power line is still connected. ZTPP staff are currently sheltering due to the attack, according to the information. DG @rafaelmgrossi expresses deep concern about the reported attack and says it must stop immediately, to avoid the danger of an extended loss of power incident at the ZNPP.

Thank you to @OAS_official @UN_OCT for the opportunity to speak yesterday about the important role of civil society in strengthening nuclear security worldwide.

Good to see reference to the IAEA’s involvement in addressing the stockpile of HEU. Properly accounting for the enriched uranium is critical. Hopefully resumption of safeguards-including Modified Code 3.1-is also included in the MoU. The sooner the IAEA gets back in the better.

What a pleasure to join Ariane and Christine for this timely conversation about the current state of nuclear weapons, nonproliferation, and the treaties and agreements that help manage nuclear risks! Take a look👇👇👇! #RevCon26 #nuclear
