Cinder'90 Code For Transmutation Calculations

The CINDER'90 code and library continue to be developed for the description of nuclide inventories produced in a wide range of radiation environments. Although generally applicable, CINDER'90 is typically applied with ancillary codes and the LAHET Code System to describe a variety of accelerator transmutation problems. The first release version of the CINDER'90 code and library LibC90a permit the calculation of inventories of 3400 nuclides of Z less than or equal to 103, using evaluated neutron reaction data below 20 MeV. Data extension efforts are now progressing to extend reaction data to 150 MeV for neutrons and protons, limited to targets of Z less than or equal to 84, in LibC90b. Public release of the code and libraries is now planned for the Fall of 1997.
