Improvement of the SUPERENERGY code

The SUPERENERGY code was imported from ANL of USA and was initially transplanted in CYBER-170/825 computer. In order to meet the requirements of China experimental fast reactor design, the authors enlarge the function of the original one with the following two contents. (1) Predicting outside and inside wall temperature of cladding, outside wall and central temperature of fuel pellet and determining the max. Temperature of cladding, max. central temperature of fuel pellet and their locations in each fuel assembly. (2) The neutronic calculation only provides the power of central pin and six pins located in the corner of hexagonal assembly, so the linear interpolation calculation is added in the code to predict the power of each fuel pin to satisfy the input requirement of the original code. As a result, the new SUPERENERGY code can satisfy the requirement for predicting the temperature field of fuel assembly
