DEVELOPMENT OF THE COMPUTER PROGRAMS CORD AND DMR IN ZEL-EN PE GEN ENERGIJA – A STATUS REVIEW
Abstract
The planned activities and results achieved in the ZEL-EN’s CORD and DMR reactor physics projects are reviewed. In the CORD project, new software tools for the numerical modelling of nuclear reactor cores in pressurized water reactors are being developed. The WIMS-D library update with nuclear data from the ENDF/B-VII.1 library was the first task in that project. The performed procedures and results of the WIMS-D benchmark test calculations with the WIMS-D libraries updated with the data from the ENDF/B-VII.0 and ENDF/B-VII.1 libraries are briefly presented. In the DMR project, a new digital reactivity meter for measuring the time-dependence of the reactivity in the reactor core is being developed. The new DMR software will run on current MS Windows systems and will be compatible with current electronic measuring equipment. Tests of the beta version of the new DMR software, presented in this paper, showed good agreement of the results for the measured reactivity with those obtained with the old DMR software, which is a validated MS-DOS application program and is considered as a reference tool.
