hello here is my concept for your logo,
i based my design on the circle shape, because the circle is the first thing that comes to my mind when im thinking about nuclear power.
i also broke the circle sometimes to express the meaning of detection
about the colors i used blue which express stabilty and tradition, but blue should not be too deep, otherwise express depression and sadness, think about the blues music and why it is called blues
please let me know if there is anything i can do to emprove it, any feedback is really welcome, thank you very much and have a great day
Mimmo
