Abstract :
An application of coupled map lattice (CML) model for simulating power fluctuations in nuclear power reactors
is presented. (1) Preservation of Gaussianity in the point model is studied in a chaotic force driven Langevin equation in
conjunction with the Gaussian-white noise driven Langevin equation. (2) Preservation of Gaussianity is also studied in the
space-dependent model with the use of a CML model near the onset of the Hopf bifurcation point. It is shown that the spatial
dimensionality decreases as the maximum eigenvalue of the system increases. The result is consistent with the observation of
neutron fluctuation in a BWR.
