PROBLEM TO BE SOLVED: To manipulate operation characteristics of a rod and/or reduce problems caused by fretting of the fuel rod by using a fuel rod using an inner fuel rod element spacer. SOLUTION: Example embodiments may include a nuclear fuel rod and/or segment design using fuel element spacers (20). The fuel element spacers (20) may be spaced at intervals in the fuel rod and/or segment for the purpose of manipulating the operation characteristics of the fuel rod (18/19) and/or segment and/or reducing consequences of fretting of the fuel rod (18/19) and/or segment. Example methods may include using the fuel rods and/or segments having fuel element (160) spacing elements, and affect the mechanical, neutronic and/or thermal properties of the fuel rod (18/19) and/or segment by controlling the space between the spacer elements.
