    "description": "<p>Unexplained neutron flux fluctuation patterns observed in some reactors were recently<br>\ninvestigated by various European institutions. The time-domain code DYN3D is one of<br>\nthe tools used for simulating these fluctuations. Though, the applicability of time-domain<br>\ncodes for modelling small stationary fluctuations remains a discussed question.<br>\nAiming at a confirmation that these codes may be applied for neutron noise calculations,<br>\ntwo special cases of neutron flux oscillations have been simulated with DYN3D and with<br>\nCORE SIM, the latter one being validated for the context here. The comparison between<br>\nthe results of these two codes is the subject of this paper.<br>\nThis study demonstrates that time- and frequency-dependent calculations can give qualitatively<br>\nequivalent results but substantial quantitative deviations may occur. Nevertheless,<br>\nDYN3D may be considered as qualified for neutron-noise calculations as the deviations<br>\nare smaller than 20 %. The optimization of the DYN3D setup is a matter of future research.</p>",
