The IAEA has been informed that an employee of the Zaporizhzhya Nuclear Power Plant (ZNPP) was killed by a drone attack today. The victim was reportedly a welder at the plant’s centralized repair workshop.
DG @rafaelmgrossi says any attack on nuclear plant staff is completely unacceptable and violates the Seven Indispensable Pillars for Nuclear Safety and Security during an armed conflict.
DG Grossi calls again for maximum military restraint to help prevent the risk of a nuclear accident during the conflict.

This one's bad: Both reactors at the D.C. Cook #nuclear plant in #Michigan ran for a month with an inoperable emergency diesel generator needed to support both units. The company knew the EDG had a problem but erroneously believed it would still work.

But how come at 9:18 PM the site said that there were currently "no operational emergencies"?
The Savannah River Site Area Emergency was terminated at 9:45 p.m. Protective actions have been lifted, and site barricades have reopened.
When more specific information is available, it will be provided to you via SRS.GOV and Facebook.com/savannahriversi….

A fire at the Savannah River National Laboratory this afternoon has triggered a Site Area Emergency. Not much additional information is available.
At this time, there is no indication of a consequence beyond the Savannah River Site boundaries.
When more specific information is available, including further media contact information, it will be provided to you through the Site’s public information staff.

An explosion in a hot cell on July 28 at the troubled Curium radioisotope facility in Noblesville, #Indiana expelled 350 millicuries of strontium and rubidium isotopes and contaminated several workers. This is the latest in a string of screw-ups there.

Someone FOIA'ed a list of #drone incursions over US #nuclear facilities since 2024. Several dozen (!) incidents showed up, some including multiple drones. Affected plants include Diablo Canyon, River Bend, TMI, Indian Point, and all Illinois stations.

If the Pentagon really believes that untested #nuclear reactors of unknown reliability and safety are going to save us from disaster, we are indeed all doomed. To the contrary, those reactors will be a magnet for attacks that could render military installations unusable.

As of 9/30, there have been 12 allegations at the still-shutdown Palisades #nuclear plant in #Michigan this year--far more than at any operating plant. This is not unexpected given all the trouble that Holtec is experiencing with the restart project.

The @NRCgov has issued its final rule on "Reviews of Reactor Designs Previously Authorized by U.S. Department of Energy or Department of War." It says this "does not affect the NRC’s commitment to conducting independent reviews." I'll hold them to that!

On Friday the Waterford-3 #nuclear reactor in #Louisiana automatically scrammed at 75 percent power after the turbine tripped as the reactor was being prepared for a refueling outage. An emergency diesel generator was actuated.

The @NRCgov has released a compilation of public comments on its proposed rule to weaken radiation protection standards for the public, workers, and the environment. It's only 12,945 pages long. Happy weekend reading everybody! nrc.gov/docs/ML2625/ML26251A…

A new localized ceasefire negotiated by IAEA Director General @rafaelmgrossi took effect this morning to help prevent a nuclear accident in Ukraine during the military conflict.
The eighth such IAEA-brokered temporary truce will enable repairs of equipment in a 330 kilovolt (kV) switchyard, close to the Zaporizhzhya Thermal Power Plant (ZTPP), that has been damaged by military activity.
This will in turn strengthen the connection between the nearby Zaporizhzhya Nuclear Power Plant (ZNPP) and its sole remaining external power line, the Ferosplavna-1, and reduce the risk of another loss of off-site power.
The ZNPP’s continued connection to the electrical grid is more important than ever as its fuel reserves for emergency diesel generators have been running low in recent months, weakening this last line of defence against a complete station blackout.
Following demining, the repair work is expected to last several days, carried out on the frontline of the conflict and monitored by an IAEA team on the ground.
DG Grossi says the Russian Federation and Ukraine engaged constructively with the IAEA to pave the way for the latest ceasefire, showing that persistent diplomatic efforts can yield concrete results that benefit both sides also in the most difficult and challenging of circumstances.
The IAEA will continue its indispensable work to ensure nuclear safety and security during the conflict, DG Grossi says.

At the @NRCgov Commission meeting today, staff just disclosed that they have already reversed recent inspection program changes that had assigned some reactor security oversight duties formerly performed by regional experts to unqualified resident inspectors. This is good.

I was traveling yesterday and missed this one. The problems are really piling up for @holtecintl at the Palisades #nuclear plant and even @NRCgov can't turn a blind eye anymore. nrc.gov/about-nrc/news-relea…

"In a few organizations [at Palisades] some people expressed hesitancy to raise concerns because of a
perception that management emphasizes production and do not want to hear about safety concerns unless they impact ongoing restart work."
