I know nuclear is expensive, but power generation isn’t the only reason to build nuclear reactors. Nuclear power plants basically prop up nuclear science. Without nuclear power plants, you’re hampering the chances of discovering a breakthrough that could lead to cheaper nuclear energy. And you’re pushing back the timeline on fusion.

Also, medical isotopes used for cancer treatments are created in nuclear reactors.

Lutetium-177 PSMA Therapy for Prostate Cancer (Pluvicto) - UChicago Medicine

Lutetium-177 (Lu-177) PSMA therapy (Pluvicto) is a new theranostic treatment that targets a specific molecule on the surface of prostate cancer cells, effectively killing the cancer cells while preserving healthy tissues.

This doesn’t seem like a good argument. More research into renewable and storage technology can also lead to interesting discoveries useful in other fields.
