Recognition as a Fellow (FNucI), our highest class of membership, demonstrates your commitment to the sector and your status as a leading nuclear professional.
Established Nuclear professionals who have significant autonomy and can demonstrate they have made 6-10 "significant contributions" to the nuclear sector over and above their job role.
This can include things like:
Nuclear Institute 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 Professionalism Standard®, 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.

We will have an expert pre-assess your suitability and give you suggestions on how to have the best chance of being accepted.

Fees and Payment
View our current Membership Fees
We will add your application fee (£60 for Associates or £90 for non-members) after your application has been received but before your application goes to committee. This will be added to your online account and should be paid before the committee date. We will email you once it's been added online.
Any fees for Member, Fellow or Professional Registration will be added after the grade or registration has been officially approved. If you are part of a company scheme and they are paying for you, we will invoice them directly. Otherwise, we will either add the fees to your online account, or set up a Direct Debit if you returned a DD form.

Please note: If we receive your application more than a week prior to the deadline, we will take the opportunity to pre-assess it. We will give you feedback if there are sections where enhancement would give you a better chance of acceptance. However, if we receive it within a week of the deadline it will go for assessment as is.
