Welcome Message

Dear ASRAM 2019 participants,

It is my great pleasure to welcome all of you to the ASRAM 2019 (Asian Symposium on Risk Assessment & Management). Nowadays, the risk assessment and management techniques are widely used in many areas including the nuclear, chemical and other industries. I am sure that the risk assessment and management techniques are one of the best ways for better tomorrow.

Even though the ASRAM was established to encourage the communications among Asian countries in the risk area, the ultimate aim of the ASRAM is to provide participants with the chances to share their findings and insights in the risk assessment and management areas with experts from all over the world.

On behalf of the ASRAM General Committee, I would like to take this opportunity to thank for the supports of KONICOF, KHNP, KEPCO E&C, FNC, PNE, and HICO for ASRAM 2019.

Finally, I would like to welcome you to Gyeongju. Gyeongju was the capital of the ancient kingdom of Silla for close to one thousand years (57 BC ~ 935 AD). Gyeongju is often referred to as “the museum without walls.” The Gyeongju Historic Area was registered as a UNESCO World Cultural Heritage in November 2000. So I hope you enjoy the cultural heritage of an ancient Korean kingdom.

Sincerely,

Joon-Eon YANGGeneral Chair, ASRAM2019Korea Atomic Energy Research Institute

Introduction to KORADKORAD was established in January 2009 to build a structure of mutual control and balance by separating management organizations from waste producers, which follows the IAEA recommendations and global standards for safe and effective management of radioactive wastes, based on the “Radioactive Waste Management Act” (2008). KORAD’s main mission is to safely and professionaly manage low and intermediate level radioactive wastes (LILW) and high level radioactive wastes, in order to enhance health and the national environment.
