Idea for Europa landing

[Novabtw2]

Is this conceptual idea good?
First the fuselage it´s made of a cylindrical shape of aluminium-lithium, carbon fiber, ´polyethylene sheets. Inside, on the top a hexagon divided to make triangles and give it more resistance, a type of biological armour made of tungsten, water, grid-patterned lead and filled with polyethylene enriched with borum also with a hexagon pattern to make it resist adverse conditions of pressure, In the energy part, it would be propelled by nuclear energy with uranium pills as fuels, hafnium and water as regulators, a turbine that makes steam. Then, the produced steam, would be compressed to heat it and be used for the engines. If this idea of engines doesn´t work, the second option could be cryogenic rocket engines. It would be also equipped with an AI integrated robot to avoid the problem of delay. In case of problems of miscommunication, Instead of the common way, it can comunicate by sending light signals bouncing on a satellite that can be translated from morse later. A drill can be used to explore the sea who is below the ice surface. Is a conceptual idea that i don´t know if it can work but i want to know your opinions
