If you want to make a WORKING model for nuclear physics, look at the Manhattan Project, and you'll be joining Miss Curie. Please rephrase the question or figure out what it is exactly you should be asking for.
Working model for what, exactly?
There are several ways one can make a working model of an earthquake. You can use an empty 2 liter bottle, clay, baking soda, and dish detergent to make a working earthquake.

a physics model can be excellent if it has a right demonstration correct working and display and capability to impress the audience right;y
Don't make it
You would not be able to obtain the fissile material necessary to build a working model of a nuclear power plant. You could build a model, for sure, but it would not be a working model.
First, get a good understanding on the "anything" you want to model.
Gyroscope will make a good working model .
If Albert Einstein had died before developing nuclear physics, it may have taken longer for advancements in the field to occur. Other scientists and researchers were also working on nuclear physics during that time, so eventually progress would likely have been made, but perhaps at a slower pace without Einstein's contributions.
how to make working model of industries
There are a few ways to make an English working model. The exact model details depend on the type of English working model you want.
There are so many ways that you can make a working model on sound. One way to create a working model is to sing.
