| Abstract: | A burnup calculation model of the lattice spectrum calculation code was introduced and two numerical solution methods for the burnup equation were given. The result of the code developed based on these two methods was compared with the result of analytical solution, and the effectiveness of these two numerical solution methods was verified. The efficiency of two numerical solution methods was also compared with each other. The Rosenbrock method shows greater advantages than the Runge-Kutta method on efficiency and precision. |
