ANS announces 2025 Presidential Citations
One of the privileges of being president of the American Nuclear Society is awarding Presidential Citations to individuals who have demonstrated outstanding effort in some manner for the benefit of ANS or the nuclear community at large. Citations are conferred twice each year, at the Annual and Winter Meetings.
ANS President Lisa Marshall has named this season’s recipients, who will receive recognition at the upcoming Annual Conference in Chicago during the Special Session on Tuesday, June 17.

The thickness of iron-based accident-tolerant fuel (ATF) cladding is discussed in this technical note because its thickness tends to be reduced from conventional zirconium alloy cladding. Structural stability may be lost if the thickness cannot withstand external pressure. Thus, the minimum allowable thickness of the ATF cladding is studied here from the viewpoint of preventing a cladding collapse. The elastic buckling theory is used to obtain the minimum thickness. The uncertainties of the mechanical properties and dimension tolerances are taken into consideration. The ovality of the cladding is also incorporated. An example calculation is carried out for APMT cladding. It is evaluated that the minimum thickness is 0.45 mm when the safety factor against the buckling is set as 2.0 and 1% of the cladding radius is accommodated for the ovality. A reference guideline of the minimum thickness depending on the mechanical property variation is suggested.
