non 1E

[DMorrison]

Is there an IEEE standard for non Class 1E equipment for nuclear plants?

Could either be just the generic standards that are not specified for the Class 1E equipment, such as IEEE-450 for batteries...or the non-class 1E equipment might impose Class 1E IEEE standards, but not impose the higher requirements necessary for dedication/qualification. It really depends on what the design specification requires.
