- 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…

Neutron number first-passage time distribution and the reactor time constant

The reactor time constant is described deterministically. In the present work, the random variable corresponding to the reactor time constant – the random time at which the random neutron number

First-passage time and change of entropy

The first-passage time is proposed as an independent thermodynamic parameter of the statistical distribution that generalizes the Gibbs distribution. The theory does not include the determination of

First passage times of mesoscopic charge transport and entropy change

The first-passage-time statistics of a stochastic process N(t) for electrons transferred through a metallic double dot are considered. It is shown that in calculating the average of the first-passage

STOCHASTIC FLUCTUATIONS IN A POWER REACTOR

The neutron and delayed neutron precursor contents and the temperature of a reactor are treated as random variables participating in a multiplicative stochastic process. It is shown that stationary

Lifetime distributions in the methods of non-equilibrium statistical operator and superstatistics

AbstractA family of non-equilibrium statistical operators is introduced which differ by the system age distribution over which the quasi-equilibrium (relevant) distribution is averaged. To describe

We consider the problem of estimating the mean entropy production rate in a nonequilibrium process from the measurements of first-passage quantities associated with a single current. For

Entropy production estimation with optimal current.

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.

First-Passage Time: A Conception Leading to Superstatistics. I. Superstatistics with Discrete Distributions

To describe the nonequilibrium states of a system we introduce a new thermodynamic parameter the lifetime (the first passage time) of a system. The statistical distributions that can be obtained out
