Abstract

Abstract

For M310 nuclear power plant, when reactor and coolant pumps trip, reverse density difference occurs in the crossover leg at seal injection condition, the natural circulation ceases if the core power decreases too much. This paper introduces the calculation model of the natural circulation, analyzes the reason for the ceasing of the natural circulation, and utilizes MATHCAD code to calculate the minimum core power.
- Natural circulation,
- Minimum power,
- Protection of boron dilution
