Wrap up: HASC chair speaks on Sentinel ‘mismanagement’; Zaporizhzhia outages and IAEA continued Ukraine presence; Y-12 emergency response exercise

By ExchangeMonitor

House Armed Services chairman Mike Rogers (R-Ala.) said Thursday that he was “troubled” by the “past mismanagement” of the Sentinel intercontinental ballistic missile program, and that it’s time to “start walking the walk” on supporting Sentinel.

“We must ensure Sentinel is ready in time to replace the current ICBMs before they reach the end of life,” Rogers said in his opening remarks of the Air Force 2026 posture hearing for its budget request, on which he said Congress has not “received any real information on.”

“Congress has been explicit about the need to address Sentinel’s cost and schedule overruns,” Rogers added. “We have authorized and appropriated funding to fix these problems. And yet, the Air Force has taken $1.2 billion of Sentinel funds and used them instead to meet other priorities in fiscal 2025. I want to be very clear: the Sentinel program is vital to modernizing our triad and ensuring nuclear deterrence.”

 

Staff living in a town adjacent to the Zaporizhzhia Nuclear Power Plant experienced power outages June 3, and water supplies in the town affected the plant itself, according to a release from the International Atomic Energy Agency.

The nearby city of Enerhodar relied on mobile diesel generators for power, while the Zaporizhzhia plant itself was connected to off-site power at all times.

Also in the release, IAEA director general Rafael Grossi said during Ukraine’s “reconstruction phase… President Zelensky and his ministers voiced strong support and appreciation for the IAEA’s continued presence at Ukraine’s nuclear sites and our essential role in helping to strengthen its energy infrastructure.”

 

Emergency response personnel conducted an emergency exercise in and around Y-12 National Security Complex on Wednesday, the site announced on its website this week.

The personnel were from the National Nuclear Security Administration as well as from Y-12’s prime contractor Consolidated Nuclear Security. The site did not publish an update on how the exercise went.

The Y-12 National Security Complex in Oak Ridge, Tenn., is NNSA’s uranium processing hub that houses the uranium-fueled, secondary stages of nuclear weapons.
