NE6766 - Nuclear Engineering Design (Spring 2015)
This course offers to the student a practical experience in the design process within the context of nuclear engineering. A definition of engineering design is: an iterative, decision-making process which has as its objective the creation of a new or improved engineering device or system which fulfills a human need or desire and which is completed in a timely fashion. Engineering design embraces the entire sequence of activities and events which occur between the recognition of a problem and the completion of specifications of a functional, economical, optimized and otherwise satisfactory solution to that problem. It includes problem definition, analysis, creative thinking, synthesis, invention, evaluation, calculation, decision-making, tradeoffs, optimization, and finalization. These processes are found in virtually every aspect of engineering management. Thus, design is the process by which the engineer applies his/her specialized knowledge, skills and point of view to the solution of problems.
