On June 2, 2026, we participated in the the Global Conference of Innovation Materials & MRS-K Spring Meeting  in jeju. 

Sehyun Cho and Hyolee Kim presented “Study on Curing Mechanism of Acid-based Geopolymer".

In addition to their presentations, the team attended various sessions related to their research interests, gaining valuable experience and insights.

On May 27-29, 2026, we participated in the 2026 Spring Conference of the Korean Radioactive Waste Society in Busan. 

Hyolee Kim presented “Review of International Case Studies on Underground Research Laboratories for Deep Geological Repository" and "Evaluation of NO3–-based NiAl LDH beads as a Potential Engineering Barrier Material".

Sehyun Cho delivered a presentation titled “International Case Study for Legacy Radioactive Waste Disposal: A Review" and "Fundamental study of Alkali- and Acid-activated Geopolymer for Solidification of LSC cocktail waste"

Yueun Kang presented “Modeling Programs for Post-Closure Safety Assessment: A Review".

In addition to their presentations, the team participated in workshops related to their research interests and attended various sessions, gaining valuable experience and insights.

Sehyun Cho was awarded the Best Poster Award at the 2026 Spring Conference of the Korean Radioactive Waste Society for his work titled:

“Immobilization Study of Cesium and Iodine in Fe-added Phosphate-Based Geopolymer Waste Form Containing Spent Ion Exchange Resin”
(with Prof. Jaehyuk Kang)

His research was recognized for demonstrating that iron-added metakaolin phosphate geopolymers can enhance the structural stability and radionuclide immobilization of spent ion-exchange resin waste forms, improving their long-term disposal safety.

On February 19, 2026, Hyolee Kim received the Graduate Excellence in Research Award and the Outstanding Scholarship. She is majoring in Energy and Chemical Engineering within the Faculty of Applied  Energy System.

Throughout her master’s studies at Jeju National University, Kim demonstrated exceptional academic performance and produced distinguished research outcomes. In recognition of her dedication, research contributions, and overall excellence during her graduate program, she was selected as a recipient of both the award and the scholarship.

The Advanced Radioactive Waste eco-Technology Laboratory at Jeju National University has been officially certified as an Excellent Laboratory in Safety Management.

This certification recognizes the laboratory’s systematic safety protocols, continuous risk assessment practices, and thorough safety education for all members. By maintaining strict compliance with safety regulations and fostering a proactive safety culture, the laboratory has demonstrated exemplary standards in research safety management.

The recognition reflects the collective efforts of professor and researchers to create a safe and responsible research environment while advancing high-quality scientific research.
