once the commercial nuclear power plant is built for electricity production , after this what kind of research does scientists do in nuclear fusion power. Why I am asking this question is ITER is planning to build the fusion reactor in 2030s , So after what research does nuclear fusion scientists do ?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.
The construction of ITER is taking so long not only because of the complications of size but also of the great number of physics disciplines covered under "nuclear fusion scientists". Starting from plasma physicists, who will continue to do research in plasma physics to electronic engineering, materials science is also important. When ITER is finished and the new reactor given over to nuclear engineering each scientist in his/her discipline will continue doing research in their field of expertise, or retire :) since it has taken so long.
In addition, there are other lines of research into fusion, like inertial fusion, which requires laser physics research interests and if it succeeds might be an alternate fusion source, which may still be ongoing after ITER finishes.
Plus there might be some smart new thinking and research going on in various laboratories that might be more efficient and advantageous in the long run they could join.
