How to apply for Fellow (FNucI)

Established Nuclear professionals who have significant autonomy and can demonstrate they have made a significant contribution to the nuclear sector over and above their job role (this can include things like publishing papers, speaking at conferences, mentorship of junior staff, outstanding technical contributions, raising the profile of nuclear, campaign work, and/or many similar activities). 

 NI Fellows are established nuclear professionals from a wide range of technical and non-technical disciplines, who apply personal behavioural standards and exercise judgement based on an understanding of the Nuclear Delta®, as applicable to their role and work context, to ensure their decisions and actions support nuclear safety and security, both now and in the future.

 Recognition as a Fellow of the NI demonstrates your standing and influence as a leading nuclear professional.

If you don’t have an NI Fellow or mentor working with you on your application, or you’re not sure if you’re at the right level to apply and/or aren’t sure how to demonstrate that you meet the criteria, we’re here to help!
We will have an expert pre-assess your suitability and give you suggestions on how to have the best chance of being accepted. Please send your CV and any specific questions that you have to membership@nuclearinst.com.
