A dynamic model of electron orbitals deformation (EODD) has been developed making it possible to allow for dynamic effects of outer electron shells screening on deuterons interactions. Computer simulation based on the EODD model revealed that deuterons in the palladium crystalline structure can approach each other so that the distance between them can be less than 0.01 and gave estimated probability of such an approach. Assuming deuterium be completely mobile in palladium, the calculated rate of the fusion reaction at 300 is 10-10- 10-12 per the D-D pair. This value corresponds to the energy release of 1-100 per gram of palladium -deuteride and is in good agreement with experimental data for excess heat measurements within an order of magnitude.
