The U.S. Nuclear Regulatory Commission (NRC) made a correction to a rule that was previously published on March 20, 2025. This rule involved updating the listing for the NAC International, Inc. MAGNASTOR® Storage System with Amendment No. 15 to Certificate of Compliance No. 1031. The correction was necessary to fix an error in the document's summary section, changing the phrase "head load" to "heat load." This rule will take effect on June 3, 2025.
Simple Explanation
The U.S. Nuclear Regulatory Commission fixed a small mistake in a rule about special boxes that safely keep old nuclear fuel. They changed the word "head" to "heat" because these boxes have to keep cool to work right.
