25th International Nuclear Graphite
Specialists' Meeting

INGSM-25 (IAEA event number is EVT2406378) will take place at THE INTERNATIONAL ATOMIC ENERGY AGENCY, which is located within the United Nations complex at Kaisermühlen, Vienna, Austria (also known as ‘UNO City’ or Vienna International Centre ‘VIC’ and adjacent to the Austria Centre ).

Delegates are expected to arrive into Vienna on Sunday 28th September and there will be a welcome reception venue to be announced in the evening.

This conference will continue the series begun at the Oak Ridge National Laboratory, Tennessee, in 2000. The annual conferences continue to explore the entire nuclear graphite life cycle and the technical issues which are presented in the design, operation and decommissioning of graphite-moderated nuclear reactors.

The previous conference held in September 2024 in Berkeley CA (USA) attracted nearly 100 delegates representing the key international design organisations, plant operators, specialised university research departments, consultants and regulators and with a particular look ahead to graphite-containing SMR designs.

INGSM presentations are archived within the IAEA Knowledge Base on Nuclear Graphite, and this will continue with presentations for the 2025 conference.

Conference Theme

Delegates will note that this conference is one day longer than in the recent past. This is to accommodate a SPECIAL DAY SESSION at the suggestion of the UK’s Nuclear Restoration Services with the special theme: International Workshop on Decommissioning Innovations for Graphite Reactors: hopefully this will include guest speakers of international status.

Panel discussions are also planned, following the success of including these in Berkeley. All suggestions for suitable topics are invited.

Abstracts are now Invited on all aspects of nuclear graphite manufacture, deployment and decommissioning, in all relevant sciences and engineering. We are keen to develop discussion and encourage development of HTR and MSR modular designs. Contributions on carbonaceous and composite materials associated with fuel or fusion systems are also included.

Abstracts of between 100 – 200 words (diagrams and figures are not recommended) should be prepared in Microsoft Word according to the ABSTRACT TEMPLATE provided. On no account should they exceed one page of A4.

Please note the requirement to provide 5 KEYWORDS (not including ‘graphite’ and ‘nuclear’!!) at the end of your abstract, which should be chosen from the available Taxonomy being developed for the IAEA Knowledge Base. You can access this via the link:
https://vocabulary-qa.iaea.org/NGKB-Taxonomy.html
Please choose no more than two words from the short general list on the opening page, then click on the alphabet keys to discover more options. Please do not use words which are not already there unless it is something obvious – like a graphite grade which is missing from the list.

Abstracts should be submitted to:

Professor Tony Wickham (conference manager) at ingsm25@gmail.com

Please use the subject line ‘INGSM-25 Abstract’ for your e-mail

Please note that the former conference e-mail address (confer@glo... ) has been compromised and should not be used. Personal e-mail address for any non-ingsm business is now wickhamtony1@gmail.com

PLEASE NOTE THIS IMPORTANT DEADLINE FOR RECEIPT OF ABSTRACTS!

Abstracts must be received by 30th JUNE 2025

Receipt of all abstracts will be acknowledged and you will be notified as soon as possible if your presentation has been accepted.

Presentations should then be prepared on the basis of a 15-minute presentation time plus 5 minutes for discussion. Please include on a final slide which will not be shown a list of key references: these will be used to augment appropriate linkages within the IAEA Knowledge Base. All presentations should be cleared in advance for release to the Knowledge Base and will be collected during the meeting.
