The application of Fast Fourier Transform (FFT) method in the twin-channel system instability under ocean conditions

Parallel-channel two-phase flow systems under ocean conditions suffer from very serious parallel-channel instability, depending on the inherent characteristics of each channel and operating conditions. The influences of ocean conditions on the instability of parallel channel are very intensive. The trajectory of mass flow is very complex, sometimes even chaos occurs. The traditional methods cannot analyze such curves effectively. In this paper, Fast Fourier Transformation (FFT) method is used to analyze the complex curve of mass flow. Based on this method the oscillation curve can be decomposed. Some basic motions and inherent characteristics can be shown by the decomposition. The accurate analysis of the influence of ocean conditions can be achievable. The onset of inherent parallel-channel instability is also analyzed.

Methods for controlling pulsed stochastic operating regimes of nuclear reactors

Methods are proposed for controlling temporal and space-time pulsed chaos in nuclear reactors where the control actions are implemented as a result of external changes in the neutron multiplication coefficient or introducing external neutron sources. Cases of periodically varying controlling actions and cases where the controlling actions are introduced at the moment the neutron pulses start are examined. The cases of a singly connected regulation system, introducing control at each point of a reactor, and multiconnected systems consisting of several regulators, introducing controlling actions in local regions of the core, are examined. The case where control is introduced in the regions where neutrons bursts start is examined. The proposed methods of control make it possible to excite or suppress pulsed stochastic regimes in reactors and change the regime characteristics purposefully. __________ Translated from Atomnaya énergiya, Vol. 101, No. 2, pp. 103–112, August, 2006.     

Calculation of the pulsed Feynman- and Rossi-alpha formulae with delayed neutrons

In previous works, the authors have developed an effective solution technique for calculating the pulsed Feynman- and Rossi-alpha formulae. Through derivation of these formulae, it was shown that the technique can easily handle various pulse shapes of the pulsed neutron source. Furthermore, it was also shown that both the deterministic (i.e., synchronizing with the pulsing of neutron source) and stochastic (non-synchronizing) Feynman-alpha formulae can be obtained with this solution technique. However, for mathematical simplicity and the sake of insight, the formal derivation was performed in a model without delayed neutrons. In this paper, to demonstrate the robustness of the technique, the pulsed Feynman- and Rossi-alpha formulae were re-derived by taking one group of delayed neutrons into account. The results show that the advantages of this technique are retained even by inclusion of the delayed neutrons. Compact explicit formulae are derived for the Feynman- and Rossi-alpha methods for various pulse shapes and pulsing methods.

A probabilistic study of the effect of retardation factor uncertainty using a compartment model for radionuclide release into the biosphere

The effect of retardation factor uncertainty with reference to the results of a compartment model, representing radionuclide release into the biosphere from a disposal facility, is studied through the application of polynomial chaos theory. We review the derivation of the working equations and apply the polynomial chaos expansion to these equations. The uncertainty in the retardation factor typically covers several orders of magnitude and stems from uncertainties in the distribution coefficient, these large uncertainties make any quantitative analysis of radionuclide release highly problematic. In this paper, we assume that the uncertainty in the retardation factor is fully described by a log-uniform distribution. We compare results using polynomial chaos against a semi-analytical solution for a short decay chain and present numerical results from polynomial chaos applied to a longer generic decay chain.
