Engineered safety feature, an emergency core cooling system at Pakistan research reactor-1

In the present study effectiveness of emergency core cooling system (ECCS) has been studied in case loss of coolant accident occurs at Pakistan research reactor (PARR-1). The reactor is a swimming pool type using MTR fuel. It was converted from highly enriched uranium (HEU) to low enriched uranium (LEU) fuel in 1992. It was also upgraded from a steady-state power level of 5–10 MW. Several additional facilities were provided to satisfy the requirements of enhanced power level. For safety consideration, emergency core cooling system (ECCS) was also installed to avoid any possibility of core meltdown. Evaluation of ECCS has been carried out for which standard correlations have been employed to find peak clad temperature profile after loss of coolant accident.
