Abstract :
The feasibility of mapping in-core power distribution by response matrix from ex-core detectors readings is discussed. Least square method is used to fitting response matrix. The response matrix is validated by comparing reconstructed power distribution with real power distribution. The result shows that reconstructed power distribution of most cells accord with real power distribution. But relative error of cell which contains bottom of control rod is large.
