1. A nuclear reactor protection system, comprising:
a first logic circuit configured in hardware to logically derive a first safety determination based at least in part on a first set of inputs, wherein the first safety determination is associated with an estimated condition of a nuclear reactor or a portion thereof,
a second logic circuit configured in hardware to logically derive a second safety determination based at least in part on a second set of inputs,
wherein the second set of inputs is separate from both the first safety determination and the first set of inputs, and
wherein the second safety determination is associated with the estimated condition and separate from the first safety determination; and
a display interface module (DIM) including a first converter circuit and a second converter circuit respectively coupled to the first and second logic circuits and configured in hardware to respectively process the first and second safety determinations or representations thereof and to provide driver functionalities for displaying the first and second safety determinations or a processing result thereof across one or more display panels that is/are directly connected to the DIM, wherein the first and second converter circuits have different designs for preserving one or more forms of diversity in processing the first and second safety determinations.
