1. A method of modifying a nuclear reactor core for uprated power operations, comprising: inputting a set of constraints to be satisfied for uprated power operations, the uprated power operations operating at greater than 100% of a currently-licensed power level for the nuclear reactor core; generating a test reactor core design based on the constraints; selecting, from a set of automated tools, one or more automated tools to evaluate the test core design against the constraints; and operating the selected automated tool, including, simulating reactor operation with the test core design, based on the constraints, to produce a plurality of outputs, comparing the outputs against the constraints, and providing data indicating constraints that were violated by the test core design during the simulation, based on the comparison, providing procedural recommendations for modifying the test reactor core design to achieve the uprated power operations based on the violated constraints, wherein one of more of the automated tools are iterated until a test core design meets all constraints for uprated power operations, thereby representing an acceptable power uprate core design.
