Two and three-dimensional model based correction of elbow tap flow measurement

A system for determining a coolant fluid flow rate in a primary cooling loop of a nuclear reactor, the system comprising:

• a processor unit;
• and
• a memory component,
• wherein the memory component is configured to store primary cooling loop physical data defining one or more measurements of mechanical components of at least a portion of the primary cooling loop, and
• wherein the memory component is configured to store one or more instructions that, when executed by the processor unit, causes the processor unit to:
• receive pressure data from a plurality of differential pressure sensors disposed within the primary cooling loop;
• calculate a model of a fluid flow through the mechanical components of the at least portion of the primary cooling loop based at least in part on the primary cooling loop physical data;
• compare the pressure data from the plurality of differential pressure sensors with estimated pressure data derived from the model of the fluid flow rate through the mechanical components of the at least portion of the primary cooling loop;
• and
• calculate a statistical weighting of the pressure data from the plurality of differential pressure sensors based on the estimated pressure data derived from the model of the fluid flow rate.
