Numerical Calculation of Response-Time Influenced by Silver Plating on Fission Couple

In this paper, the diathermanous process of fission couple was analyzed, and mathematics model was built, in which the fission-couple was separated into 3 parts of uranium, silver plating, and thermocouple leads. Two-dimension diathermanous equation, initialization and boundary conditions were given, finite difference method was used to do math disperse with the model. The influence lag time with silver plating is τ=123 ns, which was calculated using Turbo-C. This result indicates that there is no obvious effect of silver plating on the fission-couple.
