On Use of Perturbation Theory for Analysis of Periodic Pulsed Solutions in Problems of Reactor Dynamics\ A.V. Gulevich, O.F. Kukharchuk; Editorial board of journal «Izvestia visshikh uchebnikh zavedeniy. Yadernaya energetica» (Communications of Higher Schools. Nuclear Power Engineering) - Obninsk, 2009. 11 pages, 2 illustrations. References, 10 titles. Principal relationships for estimation of linear functionals due to the changes in parameters of the initial boundary-value problem on the period have been formulated based on the traditional approach of perturbation theory and the adjoint function apparatus. The emphasis has been upon the case when the problem perturbation is the change of the period itself. Numerical and analytical examples of the use of perturbation theory relationships in the simplest problems of neutronic kinetics and non-stationary heat exchange in fuel element of periodic pulsed reactor have been considered.
