Description
Modeling the dynamics of a dissipative system of interacting fuel elements of the new-generation NEPTUN pulse reactor is considered from the standpoint of Hamiltonian formalism. An exact analytical expression is obtained within the “zero” approximation, it describes the evolution of the phase portraits of the system and allows for an efficient numerical implementation on the architecture of GPU graphics processors.
The algorithm enables to find natural frequencies and oscillation modes, as well as to optimize system parameters to assess the stability of the reactor operation.
