Working outages is a great strategy for getting into a plant as a full time house employee. That is how I got my current NLO spot. I was working an outage as an RP tech and met somebody who knew somebody, etc. It helped I was ex-Navy, but the strategy is still sound. It may take a few outages to build a air of familiarity, but try and work all the outages for the same company, work hard and smart, and word will get around.
