1. Oh yea
2. Every extended minute of it.
3. 36 hours twice a year minimum - non outage years we get an extra session thrown in.
4. We have a backbone schedule of topics that are required. The general stuff is covered by that (biology, physics, math.....) We have a committee of technicians that help plan our training to make sure we get topical courses as we need them, things like outage preps (some tasks we only perform every 4 or 5 years. Training on new equipment, procedure changes, culture changes, and anything else we deem necessary.
Good luck
Jeff
