AB  - A variation of the measured neutron flux using ^3He detectors at a TRIGA Mk II nuclear research reactor during steady-state operation is reported in this article. The observed effect shows a statistically significant anti-correlation (> 7 σ) between the temperature in the reactor pool and recorded neutron count rates. Following reactor start-up under nominal operating conditions, the effect occurs for a specific time period until both thermal equilibrium and a constant neutron count rate are reached. Simultaneous neutron and temperature measurements are performed in different configurations around the reactor in order to gain qualitative insights about the temperature dependent count rate behavior.
