Detailkonzeption eines computergestützten Buchhaltungssystems

A Nuclear Material Accountancy and Control System (NACS) is described, which has been developed at KFA Jülich in accordance with the requirements of the Non-Proliferation Treaty. The main features are: - recording of nuclear material in inventory items. These are combined to from batches wherever suitable. - extrapolation of the accounting data as a replacement for detailed measurement of the inventory items data. Recording and control of nuclear material is carried out on two levelshaving access to a common data bank. The lower level deals with nuclear materials handling plus internal management while an the upper level there is a central control department which is responsible for safeguarding the nuclear materials within the entire research centre. By keeping the organizational and technical infrastructure it was possible to develop a System which is both economical and operator-oriented. In this system the emphasis of nuclear safeguarding is placed on the acquisition of the nuclear material inventory. As much consideration has been given to the interests of the various operational levels and organizational units as to internal and national regulations. Since it is Part of the safeguards and control system access to the NACS raust be restricted to a limited number of users only. Furthermore, it has a control possibility in the form of records. Authorization for access corresponds with the various tasks of the different user groups. All necessary data is acquired decentrally in the organizational units and entered via terminal. lt is available to the user groups on both levels through a central data bank. By application of NACS it is possible to minimize the effort for physical inventory taking and to improve the efficiency of inspection. In Order to meet all requirements, the NACS has been designed as an integrated, computer-assisted information system for the automated processing of the extensive and multi-level nuclear materials data. Embedded in the preventive measures of a Nuelear Material Safeguards System, the NACS enables the Operator of a nuclear plant to furnish proof of non-diversion of nuclear material
