The U.S. Nuclear Regulatory Commission (NRC) is considering an amendment to the operating license of the Callaway Plant, Unit No. 1, operated by Union Electric Company, also known as Ameren Missouri. The proposed amendment would allow the plant to operate with 52 control rods during its 28th cycle, instead of the currently required 53, due to a slowed drop time observed in one control rod. The NRC plans to issue the amendment if it determines that it does not involve significant hazards. The public can comment on this proposal or request a hearing by specific deadlines.
Simple Explanation
The people in charge of a big electricity plant think it's okay to use one less special stick (called a control rod) than normal to help make electricity safely. They want to let everyone know they plan to make this change and that people can say what they think about it or ask questions by a certain time.
