Chicken Little. The structural work in U.S. Nuclear power plants is designed to codes that are conservative to a fault. I have doing Nuclear structure work for about four years and IMO they will withstand impacts 5-6 times of what they are designed for. Even if burning fuel reduced the modulus of elastisity to 10 or 20% nothing would fall down. The plants located in seismic active areas are even more robust, designed for peak loads of up to 35 G's or more.

This is THEIR Report (NRC) just 3 months ago.

Are you saying the NRC does not know what they are taking about or what they are doing ?
