In the last billion it is said to be about 140 C, but in the next 100 years it will be alot more than that. We are pumping more and more water down to the core to make Hydro Dynamic power that it eventually has to start making an effect on core temperature

I do not now the answer but I would like to point out a few things. First off, temperature is measured in degrees and heat is measured in calories. Also, the assumption has to be made that the thermonuclear decay of radioactive elements is changing at at constant (albeit logarithmic) rate. This would assume that no new material is being input into the Earth, or at least that the input was constant also. Geology does not know if this is true, but the moon, and therefore the Earth also, was bombarded by space debris some 3.9 billion years ago. Assuming constant logarithmic decay with a known amount of heat being removed today it is a simple process to set up an integral and calculate the amount lost in the last billion years, but I don't like doing calculus so I am not going to figure it out.
