ABOUT Helsinki

Helsinki, the capital of Finland, is a vibrant seaside city of beautiful islands and great green parks. The city’s rhythm is laid back yet at the same time refreshingly active. Helsinki’s boulevards and backstreets overflow with magnificent architecture, intriguing drinking and dining venues and groundbreaking design. Read more at:


Citizens from countries outside of the Schengen area might need a visa to enter Finland. Check here if you need a visa.

Upon request, the European Nuclear Society will prepare a visa invitation letter for delegates whose registration fees were received in full. Unfortunately, we are not in a position to give any further support to the visa application process. Obtaining a visa remains the sole responsibility of the participant. Regular cancellation deadlines apply, regardless of whether your visa was granted or not.


Due to the COVID-19 Pandemic, Finnish Authorities still maintain some limitations to border traffic.  The Finnish border guard provides passengers with up-to-date  information on the changes that apply to entry to Finland.

IAEA Travel Grants

The IAEA offers a limited number of travel grants which contribute to meeting the grantee’s travel and accommodation expenses. The grants aim to stimulate the attendance of selected professionals in the research reactor community who would have difficulties attending The European Research Reactor Conference (RRFM) 2021 without this assistance. The IAEA invites particularly young people to apply for a travel grant.

The criteria for selection are:

  • The candidate must be a national from an IAEA Member State eligible to receive assistance under the Agency’s Technical Co-operation
  • The candidate must present an oral paper or poster accepted by the Programme Committee

Priority will go to first-time applicants.

If you are interested in a travel grant, please fill in this Grant Application Form, and send it back via your official National authority (Ministry of Foreign Affairs or National Atomic Energy Authority) to:

International Atomic Energy Agency
Vienna International Centre
P.O. Box 100
A-1400 Vienna

This form should be returned through the official liaison offices with the IAEA by 15 August 2021 at the very latest. To start the procedure in due time (sending it through the post may take some time) you may anticipate the form by fax (+43 1 26007) or by e-mail to, with cc Mr. Petr Chakrov (


The European Research Reactor Conference (RRFM) 2021 will be organised in a hybrid format with live streaming of presentations to and from the conference room. Delegates will have the possibility to attend on-site or remotely.

In this hybrid format, the European Research Reactor Conference (RRFM) 2021 offers the following registration categories:

  • On-site participation 790€ (ex. VAT)
  • Remote participation 590€ (ex. VAT)

Rates are stated exclusive Value Added Tax (VAT). According to EU and Finnish Law, 22% VAT must be charged to all participants originating from in and outside the EU. This tax will be added to your invoice. Delegates from VAT registered entities will be able to recover the paid VAT through their own tax declaration.

Call for Papers

The Programme Committee of the European Research Reactor Conference (RRFM)  invites authors to submit abstracts for the 2021 edition of the conference.

The conference will combine an in-person conference with an online event which allows delegates who cannot or who don’t want to travel to Helsinki to participate and present their paper.

Important Dates

NEW Deadline for abstract submission: 31 July 2021
Deadline for full paper submission: 27 August 2021
Conference: 24-29 September 2021

Authors Resources
This conference is meant to include all research reactors of all powers, critical and sub-critical facilities.
The Programme Committee  is calling for both oral and poster presentations on the following topics:
  • Research reactor nuclear fuel cycle from front-end to back-end– conversion to LEU fuels; fissile material supply; fresh fuel and targets: origin, fuel development, qualification, fabrication; in-core fuel management and safety; fuel transportation; fuel and reactor licensing; fuel back-end management including reprocessing, spent fuel storage, corrosion and degradation; fuel cycle economics.
  • Utilisation of research reactors – capacity building; E&T programmes; nuclear science and technology including support for nuclear power programmes; neutron beam applications; industrial and medical applications, including radio-isotopes production and irradiation/transmutation technology; strategic and business plans; networks and coalitions.
