How to apply for Member (MNucI)

Nuclear professionals working at all levels in the nuclear sector and its supply chain. You need to have at least 2 years’ postgraduate experience in the Nuclear sector (if you’re less experienced, or have been working at an apprenticeship level, we’d welcome an application at the Associate grade). 

 NI Members are practising 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.

NI Members also commit to comply with the NI Code of Conduct.

 Recognition as a professional Member (MNucI) of the NI provides independent verification of your nuclear professionalism, whatever your specialism, job role and work context.

If you don’t have an NI Member or mentor working with you on your application and you’re not sure if you’re at the right level to apply, 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.

We are licensed by the Engineering Council, the Science Council and the Society for the Environment, to assess applicants for entry onto the respective professional registers, at the registration grades of Chartered Engineer, Chartered Scientist, Chartered Environmentalist, Incorporated Engineer, Engineering Technician and Registered Environmental Technician.

Applicants should check the eligibility criteria before completing an application:
CEng
IEng
EngTech
CSci
CEnv
REnvTech

Applicants for CEng or IEng must have qualifications recognised by the Engineering Council (check here).

If you don't have the right qualifications, please ask us for an equivalence application to support your CEng or IEng application.

Please note that you must either be, or be in the process of applying to become, an NI Member or Fellow before you can apply for an additional professional registration. If you have a question, please contact membership@nuclearinst.com

Complete the relevant application form for Member (MF1) and email it to membership@nuclearinst.com with the supporting documentation requested on the form.

You can find the application forms for all grades on the Nuclear Professionalism Standard page: https://nuclearinst.com/nuclear-professionalism-standard

If also applying for Professional Registration, please make sure you've read the previous section (Professional Registration)

The Nuclear Professionalism Standard replaces the Nuclear Delta. We will still accept applications made under the Nuclear Delta until 1 May 2025. If you need to request a form for that, please email us.

All enquiries should go to membership@nuclearinst.com

Fees and Payment

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.

2025 Application dates

The closing date for the Membership Committee to consider membership and professional registration applications in 2025 are:

• 23 January 2025
• 1 May 2025
• 31 July 2025
• 30 October 2025

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. 

For further guidance and support please access the NI Membership Resources before completing your application.
