Determination of Computational Bias for Sub-critical Configuration of VR-1

Popis výsledku v původním jazyce

This paper describes sub-critical experiments performed on the zero-power reactor VR-1 in Prague. Measurable states of the core sub-criticality were achieved by the sub-critical multiplication method. Reactivity or multiplication factor was determined by Source multiplication method known as Greenspan Method. This method is simple and reliable. Requirement for this method is to know a slope of the reactor power increase from critical state after neutron source injection. Measurements were carried out for different power level and position of detectors. For each case, the model for MCNP and SCALE was prepared. Comparison of experimental and calculated values will identify the trends and reliance of the computational bias to depth of sub-criticality. In special case it can define requirements on standard benchmark experiment for PWRs. This paper also gives a brief description of the experimental reactor VR-1 and equipment used within the analysis.
