| Outline of Final Research Achievements |
This research was conducted for the real-time subcriticality monitoring in high gamma dose rate field. In order to estimate a measurement error of subcriticality, statistical error estimation methods were newly developed for subcritical measurement technique by the reactor noise analysis method. Using the data assimilation method, it was confirmed that the uncertainty of the measured subcriticality could be reduced even under a situation where parameters required for subcriticality measurement (e.g. one-point kinetics parameters) have uncertainties. In order to investigate the applicability of a prototype detector of "Transparent RUbber SheeT type (TRUST) Eu doped LiCaAlF6 (Eu:LiCAF) scintillator" to the reactor noise measurement, preliminary experiments were carried out under high gamma dose rate field at the Nagoya University Cobalt 60 irradiation facility.
