METHOD FOR NOISE CONTROL OF NUCLEAR SAFETY PARAMETERS FOR SPENT NUCLEAR FUEL STORAGE Russian patent published in 2017 - IPC G21C17/104 G21F9/34 

FIELD: physics.

SUBSTANCE: invention relates to the technology of nuclear fuel storage at nuclear power facilities and can be used for the experimental determination of nuclear safety parameters - reactivity and the effective multiplication factor - storage pools (SP) of spent nuclear fuel storage facilities (SNFS) of nuclear power plants (NPP). The method for controlling NPP SNFS SP nuclear safety parameters involves measurement of the neutron flux in the stationary undisturbed state as the detector noise time series, the time series is modeled by a autoregression equation of the first order, the coefficients of which are related to reactivity according to the kinetics equation and are assessed based on the detector readings.

EFFECT: invention improves NPP SNFS SP nuclear safety and adequacy of security settings definition by reduction of the number of a priori calculated values and ensuring of ongoing continuous monitoring of NPP SNFS SP safety parameters.
