You appear to be looking at technical jobs, but your resume is professional. The CHP that is polishing your resume is looking at it from the wrong viewpoint, on 2 directions. He is not in commerical nuclear power (life IS different here) and not technically based. Most utilities screen their resumes based upon matching the keywords in the training and experience to the requirements on the job posting. If you write a glowing resume about how you work for the State, and have a Physics degree, when the utility is looking for a technician that has 3 years commercial power or Navy Nuke experience, your resume gets filed. Sorry, you didn't answer the question properly.
You are IN government beauracracy. You have a few NRC courses, a physics degree, and participate (as a State Regulator) in site emergency drills. Those drills are about as close to day to day work reality as Honey Boo Boo is to a real family. Look at openings that you would be good at, and are challenging. Don't just "want to get into nuke power"
I'm not sure what else you have been applying for, but an (1) electronics course doesn't meet the minimum standards for entry level I&C tech.
From your post, the thing I see you being qualified to apply for is a junior engineer / specialist in Licensing, or Emergency Planning. You don't seem to meet the requirements for any technical position (no actual hands on experience) that would make you stand out above an experienced nukeworker.
It's not your gender - my site has several competent, respected females in engineering, operations, management, and technical jobs. Somehow, you need to focus your resume / application on the openings that you can stand out in, and not expect that having a degree and a few NRC courses (which are generally not considered real in the commercial industry) make you qualified for every position.
Good Luck, I hope you find an opportunity.
