Which operational risk rises during sustained nuclear reactor fission?

💡 Explanation

Neutron flux spatial oscillations increase because localized power shifts affect fission rates via feedback loops – a kinetic instability mechanism. Therefore control challenges rise, rather than simply material degradation or effluent processing limitations under typical load.
