An annular disc fin is a common choice to enhance heat from a cylindrical primary surface. In nuclear applications, heat transfer from the fin surface is due to convection and radiation and heat also generated in the fin. With radiation and heat generation, an analysis is presented. A closed-form analysis based on the differential transform method was established for fin heat transfer. As heat is generated, it is suggested to determine the fin heat transfer by an integral approach, and an integrodifferential formulation to the differential transform function was implemented newly and is the only way for calculating the heat transfer rate for the internal heat generation in the fin. This method is introduced in the literature for the first time for annular disc fins. The effects of heat generation on the fin performance parameters were studied under a design condition. A new scheme for the optimization study with variation of heat generation was carried out to provide a superior aspect of the thermal design of annular fins. For the simplification of analysis to a designer, approximate methods were also established for a design condition taken in the analysis.
