I need to find a way to use sodium in a calorimeter system.
Most calorimeters use water, but water and sodium is explosive, so what can i use as a substitute for water?

Liquid hydrocarbons. Kerosene is one example of a mixture of hydrocarbons. It provides an inert atmosphere for sodium and does not react with it.

Here is a useful reference to specific heat capacities of common substances:
