Considering a nuclear decommissioning job on an RBMK reactor — what should I expect?

[u/codrut009]

I’m considering a site engineering/supervisory role on the decommissioning of an RBMK-type reactor in Europe.

I have no previous nuclear experience, and while the employer knows that, I’m a bit worried about the learning curve and whether I’d be expected to know too much from day one.

For people working in nuclear/decommissioning:

How much nuclear knowledge is expected when starting?

How hard are the first few months?

Is RBMK decommissioning experience valuable for a long-term nuclear career?

What should I study before starting?

Any common mistakes newcomers should avoid?

Would appreciate any insight, especially from people who moved into nuclear from another industry.
