Angra-1 operational control systems representation with RELAP5/MOD2 code

  • 1. Comissao Nacional de Energia Nuclear (CNEN), Rio de Janeiro, RJ (Brazil)

Description

The following automatic control systems for Angra-1 NPP were simulated with the RELAP5/MOD2 code: rod control system, steam generator level control system, feedwater bypass valve control system, pressurizer pressure control system and pressurizer level control system. The paper shows the results of two transients: a ten percent step load change and a five percent per minute ramp load change. Satisfactory quantitative and qualitative results were obtained when comparing these results with thermal-hydraulic NPP programmed-values. (author). 7 refs., 13 figs
