Description

The necessity, demand and status to online monitor the in-core power distribution of HTR are reviewed. The methodology to reconstruct in real-time the in-core power distribution from the finite number of ex-core detector readings is introduced. The difficulty and key issues induced by particularity of HTR are discussed. The research progress, including high order harmonics calculation on cylindrical geometry, three-dimensional diffusion model with accurately modeled control rod region, three-dimensional ex-core detector spatial response function calculated by adjoint discrete ordinates transport method, are presented.
