New Analysis of the Experiment for Measurement of PHI > 1 MeV in Pressure Vessel Cavity of US Light Water Power Reactor, Arkansas

摘要

The new method of multiple unfolding has been applied to the analysis of a complex experiment having as object the evaluation of absolute value of PHI > 1 MeV in the pressure vessel cavity of Arkansas P and L reactor. This approach is different with respect to that used by NBS team in a precendent evaluation. The results show a gain in the accuracy if the multiple unfolding is used and, at the same time, the importance of use of covariances for a good propagation of errors. 18 refs.
