Computer-aided design of cable nets for nuclear power plants

An ES 1033 computer was used for designing cable lines through several separate systems while assuring the safety of nuclear power plants. This because the design of the cable systems exceeds the possibility of the project design offices in question. Used as input data were orders nd lists of cable connections, routes and their equipment. The method of checking and modifying input data is described. The cable route is searched for in the working memory into which were read 4 fields describing the cable routes for the processed systems. The algorithm is described for the selection of the optimum route. With regard to output documentation, instructions were written for the processing of the inventory of cable connections bedded in the routes and of cable sections. The program is written in the PL/1 language and allows to process the laying of up to 6000 cables in the layout of the cable area. (J.C.)
