The source term calculation capability is developed for the high-fidelity neutronics code NECP-X. Generally, a full activation library used, but memory requirement unacceptable calculation. In order to minimize during with very strict conditions, new generalized chain compressed method proposed based on influence qualification. One basic compression element reaction channel or an isotope, and o...

Fast and accurate identification of source locations release rates is particularly important for improving indoor air quality ensuring the safety health people. Existing methods based on adjoint probability are difficult to distinguish rate dynamic sources, optimization algorithms regularization limited analysing only a small amount potential pollutant information. Therefore, this study propose...
