The present invention relates to a tubular fuel rod and a method of manufacturing the same, specifically, the tubular fuel rod is characterized in that the tubular nuclear fuel is inserted into the outer peripheral surface of the Al base formed of a rod or tube, Al is coated on the outer peripheral surface of the tubular fuel, The manufacturing method is characterized in that it comprises the step of preparing and inserting a tubular nuclear fuel with a constant diameter to the outer peripheral surface of the Al base formed of a rod or tube, and coating Al on the outer peripheral surface of the nuclear fuel.n n n The tubular fuel rod according to the present invention minimizes the contact surface between the fuel and Al, prevents excessive reaction between the fuel and Al to suppress the formation of the reaction layer, thereby minimizing the occurrence of swelling amount and minimizing temperature rise, thereby improving nuclear fuel stability. Has an effect. |
