The CCONE code system and its application to nuclear data evaluation for fission and other reactions

Iwamoto, Osamu; Iwamoto, Nobuyuki ; Kunieda, Satoshi; Minato, Futoshi; Shibata, Keiichi

A computer code system, CCONE, was developed for nuclear data evaluation in the JENDL project. The CCONE code system integrates various nuclear reaction models needed to describe nucleon, light charged nuclei up to alpha-particle and photon induced reactions. The code is written in the C++ programming language using an object-oriented technology. At first, it was applied to neutron-induced reaction data on actinides, which were compiled into JENDL Actinide File 2008 and JENDL-4.0. It has been extensively used in various nuclear data evaluation not only for actinides but also for non-actinide nuclei. The CCONE code has been upgraded to nuclear data evaluation at higher incident energies for neutron-, proton-, and photon-induced reactions. It was also used for estimating $$beta$$-delayed neutron emission. This paper describes the CCONE code system indicating the concept and design of coding and inputs. Details of formulation formodelings of the direct, pre-equilibrium and compound reactions are presented. Applications to the nuclear data evaluations such as neutron-induced reactions on actinides and medium-heavy nuclei, high-energy nucleon-induced reactions, photonuclear reaction and $$beta$$-delayed neutron emission are mentioned.
