The NEA Data Bank collects and distributes computer programs which fall into one of the following subject categories. Click on the category name to access the index to computer categories by these categories.
This list contains the nuclear model codes and their classification contained in the OECD/NEA Data Bank collection.
They are given in alphabetical order by program name. Every program has an "abstract number" assigned in order to make the identification of the program unique. At the end of the list a brief description is provided. Hyperlinks give access to more detailed information.
Computer codes labelled NEA were developed in Data Bank member countries, those labelled CCC and PSR have been packaged at RSICC (the Radiation Safety Information Computational Center), those labelled NESC have been packaged at the former National Energy Software Center, those labelled USCD are of US origin but were released from a university. All those labelled IAEA were developed in IAEA member countries which are not members of the OECD.
