Sažetak
NPP Krško (NEK) input deck for best-estimate computer code TRACE is being developed at Faculty of Electrical Engineering and Computing (FER), Zagreb. The TRAC/RELAP Advanced Computational Engine (TRACE) is an advanced, best-estimate reactor systems code developed by the U.S. Nuclear Regulatory Commission for analyzing transient and steady state behavior in light water reactor. At FER, a detailed RELAP5/MOD 3.3 model for NPP Krško has been developed. The model encompasses detailed models of control and protection systems, e.g., Automatic Rod Control system, Safety Injection System, pressurizer pressure and level control system, steam generator level control system, steam dump control, etc. The model is being constantly upgraded in accordance to plant modifications. The RELAP5/MOD 3.3 input deck for NPP Krško was used as a basis for development of NPP Krško model for TRACE 5.0p5 code. In the paper the results of steady state qualification (first 1000 s) for both RELAP5 and TRACE are assessed against plant referent data. For on-transient qualification of a developed TRACE model, 3 inch small break LOCA accident in a loop with pressurizer was analyzed and the results were compared with RELAP5 results. In the analysis all the Engineering Safety Features (ESFs) with a minimum delay were assumed available. The transient was simulated for 10000 seconds.
