Hi Fozzzworth. Thanks for your post!
That is great you would like to write and teach others about subjects you feeling strongly about! Since you are just starting your career, you could start to create a name for yourself in the field by just blogging about nuclear power. I look who are successful in blogging about nuclear and we have two of them on this site. As I understand it, Dan and Rod's syndicated blogs are part time passions for them. They both have full time jobs and Dan actually writes for different publications. My point is if you create a name for yourself, people will notice and opportunities could arise from it.
If you would like to start a blog, I would be happy to offer you your own nuclear blog on this site for free. If you are interested, send me a PM.
