Nuclear Safety & Risk
Advanced safety technologies, radiation monitoring and risk assessment for nuclear and non-energy applications.
View research focusCity University of Hong Kong · College of Engineering
Advancing nuclear safety through materials, modelling and multidisciplinary research.
ANSD connects fundamental science with engineering solutions for safer nuclear systems, resilient materials and sustainable technologies.
Our purpose
Research that moves from atomic behaviour to societal safety.
We bring together expertise in nuclear safety, risk assessment, materials under extreme environments, computational materials science and sustainable applications. Our goal is to build research partnerships with lasting impact in Hong Kong, the Greater Bay Area and the international community.
Research
Four connected areas of inquiry
From risk and reliability to material behaviour at the atomic scale, our research addresses safety as a connected system.
Materials in Extreme Environments
How irradiation, temperature and mechanical loading reshape structure and performance.
View research focusComputational Materials Science
Atomistic and multiscale modelling that connects mechanisms with engineering response.
View research focusSustainable Technologies
Smart materials, energy harvesting and storage, nanostructures and medical applications.
View research focusCollaborative research platforms
Shared facilities that turn questions into evidence.
These representative platforms are hosted and operated by ANSD’s closely collaborating units. ANSD researchers access them through collaboration; they are not ANSD-owned facilities.
01 · Collaborative atomic-scale analysis
Atom Probe Tomography
The Inter-University 3D Atom Probe Tomography Unit, equipped with a LEAP 5000 XR, supports near-atomic-resolution three-dimensional compositional analysis and collaborative materials research.

02 · Characterisation and testing
Integrated materials analysis
Computation, microscopy, focused-ion-beam preparation, ion milling and mechanical testing provide connected routes from microstructure to measured performance.

03 · Collaborative partner platforms
Corrosion and irradiation partner platforms
These specialised high-temperature lead–bismuth corrosion and ion-irradiation facilities are partner platforms hosted and operated by ANSD’s collaborating units, not ANSD-owned facilities. ANSD researchers access them through collaboration to investigate degradation mechanisms relevant to advanced nuclear-energy systems.
Our research team
People advancing materials for demanding conditions.
Led by the Centre Director, ANSD’s current research team brings together six Postdoctoral Fellows—including one part-time appointment—working across complex alloys, irradiation response, nanomechanics and materials design.
Public engagement
Clear evidence for an informed conversation about nuclear safety.
ANSD provides a platform for education and public discussion on nuclear technology, its societal impact and sustainable development in Hong Kong.
