    The Nuclear Regulatory Commission (NRC) confirms that on April 21, 2025, a new rule will be enacted. This rule updates the spent fuel storage regulations, specifically revising the listing of the Holtec International HI-STORM UMAX Canister Storage System. The updates focus on radiation protection specifications, including clarifying dose rate limits and modifying their values and measurement locations. Since no major issues were raised in public comments, the rule will proceed as planned.

    Simple Explanation

    The government is making sure that special rules for safely storing used nuclear fuel will be updated soon, which means they will make sure everything is extra safe when they lock away old nuclear stuff. Nobody had big problems with this plan, so they’ll go ahead with it.

  • 2025-04441 — Airworthiness Directives; Pratt & Whitney Canada Corp. Engines
    Type:Rule
    Citation:90 FR 12679
    Reading Time:about 9 minutes

    The Federal Aviation Administration (FAA) has issued a final rule to adopt a new airworthiness directive (AD) for certain Pratt & Whitney Canada Corp. engines, specifically the PW535E and PW535E1 models. This directive is in response to findings from a design review that showed some bolts on the engines might crack due to low-cycle fatigue, which poses a safety risk. The AD mandates routine inspections and potential replacements of these bolts to prevent any danger to the aircraft. Compliance with these rules is required by April 23, 2025, and aims to ensure the continued safe operation of aircraft using these engines.

    Simple Explanation

    The FAA says some airplanes with certain engines have bolts that might break from being used too much, so they need to be checked and maybe replaced by April 23, 2025, to keep flying safely.
