Influence of entropy changes on reactor period
@inproceedings{Ryazanov2022InfluenceOE, title={Influence of entropy changes on reactor period}, author={V. V. Ryazanov}, year={2022} }
- The reactor period is considered as a random variable. - The effect of entropy changes on the reactor period is taken into account. - It is possible to evaluate the contributions from various methods of reactor control. - The dispersion and other moments of the reactor period are determined. The period of a nuclear reactor is considered as the average value of the first passage time. The reactor period is considered as a random variable. This approach makes it possible to find the effect of…

By proving the saturation of the thermodynamic uncertainty relation in the short-time limit, the exact estimate of the entropy production can be obtained for overdamped Langevin systems, irrespective of the underlying dynamics.
