I guess I should have mentioned that I do include thermal storage within the materials. This behaves much like a capacitor and charge. That is what determines the time domain characteristics of my model.
I was referring to a different type of delay, such as one that might show up if the temperature were applied to the core for a period of time and then some internal nuclear process, or whatever, begins to put out energy that builds up with time to its final value. The other normal case is handled well. It seems as though a two time constant system works well at the present time.

I suppose that they could also be incorporated if there is a good reason to believe that they are present and important. The cooling will always be delayed somewhat, due to the slow speed of thermal conduction. Hence thermal resistance will always play a crucial role. The lower the resistance, the faster the cooling can respond, and the more easily a high value exponent function can be controlled.
