NERIS Workshop 2026 – presentations

Feedback

The 12th NERIS Workshop took place at ASNR headquarters in Fontenay-aux-Roses, on 28-29-30 April 2026. For the first time in years, this Workshop ran on 2,5 days. The Workshop gathered around 70 participants, coming from 20 countries, among which 2 outside of Europe (Canada and South Korea).

Agenda

The Workshop provided 33 presentations covering :

Frameworks and lessons learned in EPRR,
EPR&R in armed conflicts, nuclear detonations, with presentations from CITISTRA, PREDICT and RRADEW,
Countermeasures, decision support, disaster informatics,
EPRR for New Nuclear Technologies, with presentations from CATAPULT and GIROSCOPE,
Radiological impact assessment,
Presentations from CITHARA.
