Analysis of CSF Model for a Simulated Loss of Coolant Accident Conditions

ABSTRACT

An experimental facility called Containment Studies Facility (CSF) has been constructed at Bhabha Atomic Research Centre (BARC) for the purpose of research and development in the area of nuclear reactor containment thermal hydraulics. The facility consists of reinforced concrete containment structural model (CM) and a Primary Heat Transport Model (PHTM) vessel. The containment model of CSF is divided into high enthalpy V1 volume (dry well) and low enthalpy V2 volume (wet well). The PHTM with a pressure vessel and associated pump and piping system is designed for simulating the Loss of Coolant Accident (LOCA) conditions within the containment model. Experiments were carried out in CSF for 30bar blowdown conditions. Pressure, temperature and other transient parameters were recorded. The measured results were compared with outputs of modeling carried out using RELAP code and in-house containment thermal hydraulic code CONTRAN.
