1. A method for determining and updating a projected strategy for maintaining optimal operations of a nuclear reactor based on one or more optimization input parameters and/or reactor state-point information stored in a database, comprising the steps performed by a computer or computer network of: a) accepting input data for initializing or modifying one or more optimization input parameter values which collectively define a particular reactor operation strategy; b) computing optimized quantitative values for a plurality of reactor core operational control-variables based on current reactor plant state-point data, wherein the computed optimized quantitative values meet predetermined design constraints for the reactor; and c) displaying, on a display device coupled to said computer or computer network, at least one or more of said computed optimized quantitative control-variable values, said information being indicative of a projected strategy for optimal reactor performance.
