Date: 2–5 September 2025
Venue: Meeting Room #2, Conference Hall, Hokkaido University, Sapporo, Japan

Poster

Overview

The purpose of this workshop is to share activities related to nuclear data, such as measurement, evaluation, validation, and EXFOR compilation, and to discuss future collaborations in Asia.

AASPP2025 continues the series of previous workshops held in Sapporo (2010, 2015), Beijing (2011, 2016), Pohang (2012), Almaty (2013, 2019), Mumbai (2014), Ulaanbaatar (2017), and Daejeon (2018). The workshop is coordinated by the Asian Centres of the International Network of Nuclear Reaction Data Centres (NRDC) with support from the Nuclear Data Section of the IAEA.

The proceedings will be published as an INDC country report.
