Abstract :In this paper, Joint Evaluated Fission and Fusion insert ignore into journalissuearticles values(JEFF); Nuclear Data Library has been used to calculate the nuclear decay heat after a fission burst of 235 U and 239 Pu for shutdown time up to 10 5 sec. This estimation is based on the numerical solution of the linear differential equations that describe buildups and decays of the fission products. The code was written in MATLAB, which is fast and easy-access platform. The verification of the current code is carried out by comparing the numerical results with the measured reported ones. The discrepancies between the evaluated results and the measured ones show the reliability of the current calculation.
