[en] A system of data processing and accounting for industrial plants is being developed for nuclear material safeguards in the field of peaceful application of nuclear energy. A modular highly flexible software system has been worked out which is generally applicable with slight modification, taking into account the differences in industrial plants. The model of the fabrication plant is based on a structure of material balance areas (MBA). The computer system is described and contains the following programs: (1) system-generating program; (2) data-collection program; (3) information program; and (4) the special program. The system allows one to obtain rapid and complete information about the fissile material flow, MUF per MBA or per project, the shipper-receiver difference, etc. First an off-line system will be developed by the end of 1975 in the nuclear fuel element plant Nukem at Hanau in the Federal Republic of Germany.

[en] A minicomputer-based system for nuclear materials control is presented. Significant properties of the system are interactive data entry by the plant operators themselves, user-oriented dialogues and user-independent internal data representation, and description of user processes by means of basic functions. 1 ref

[en] Untrained users and a large amount of--at first glance incompatible--processes and materials are the environment of computer-aided nuclear materials control systems. To find an efficient model of the real processes and materials descriptions and to allow the operating personnel to communicate with the system in his everyday symbolism are goals in the development of the concept presented in this paper. According to this concept a real-time minicomputer-based materials control system is being implemented in the Nuclear Research Center of Karlsruhe. The chosen approach satisfies the heterogeneous requirements of the various institutes of the Center and is also applicable to other nuclear plants

[en] One of the basic problems in designing nuclear materials control systems is to handle and store the information necessary for plant operation and safeguards purposes. The method presented in this paper describes all kinds of nuclear material having different characteristics with a uniform and efficient data scheme. It is used to build up the data base of the nuclear materials control system for the Karlsruhe Nuclear Research Centre. (author)
