Kinetic parameters evaluation of PWRs using static cell and core calculation codes

► In this study, we have calculated effective delayed neutron fraction and prompt neutron lifetime in PWRs. ► New software has been developed to link the WIMS, BORGES and CITATION codes in Visual C# computer programming language. ► This software is used for calculation of the kinetic parameters in a typical VVER-1000 and NOK Beznau reactor. ► The ratios (βeff)i(βeff)core, which are the important input data for the reactivity accident analysis, are also calculated.
