Likely requirements

Our reading of the notice. Always check the tender documents.

This contract almost certainly requires nuclear industry security clearance (which takes 4–8 weeks and excludes many applicants), proven experience with radioactive systems, advanced design and manufacturing capability, and quality certifications. Most one-person or small local trades will not meet these barriers.
