A method and apparatus for continuous nuclear power distribution synthesis.

摘要

The present invention provides a power distribution synthesis method and apparatus that uses a small number of local axial power distributions determined from less than a full complement of fixed incore neutron detectors (16) and a power sharing map produced from a full complement of core exit thermocouple (18) temperature signals to synthesize the full core (12) power distribution (62). The localized tilt of the core (12) is determined (70 and 72) from the power sharing map and used to remove (76 and 82) the tilt from the local distribution. The tilt adjusted local distribution is assigned to symmetric core (12) locations where uninstrumented core power values are determined by interpolation (90-120). The interpolated, assigned and tilt corrected local distribution power values are transformed into the three dimensional power distribution using the tilt.
