Abstract

Abstract

This paper presents the Rossi-α method for the micro-noise analysis in the reactor physics ex-periments,which is applied in the study of measurement of the kinetic parameter,α eigen value,of Tsinghua University’s Sub-Critical Facility.The measurement is performed under extremely low flux condition,and α_c,the critical α eigenvalue,is obtained by the way of extrapolation.Meanwhile,the theoretical calculation has been carried out based on MCNP and TMCC codes.Results from measurement and calculation agree well with each other.
