Current PHITS cannot simulate precisely the behavior in the materials. Thus, we have developed track structure code, also have an implementation plan of the code into PHITS. We calculated the microscopic behavior of the electron in water by using the developed code. As the results, we could predict theoretically that the electron thermalization progress contemporaneously with formation of prehydrated electron against previous prediction. We report our outcomes obtained from the developed track structure code, future plan for and implementation of the code into the PHITS.
