The full-scale engineered barrier system (EBS) performance experiment for vertical EBS emplacement has been conducted at the Horonobe Underground Research Laboratory (Horonobe EBS experiment) with the aims of understanding the T-H-M-C coupled processes, obtaining the T-H-M-C coupled data and testing the T-H-M-C coupled simulation code. The Horonobe EBS experiment will be dismantled in Task C as part of an international project called "Horonobe International Project (HIP)". The objective of Task C is to understand the T-H-M-C coupled simulation processes in more detail using the data obtained from the dismantling EBS experiment. In order to elaborate the dismantling experiment plan, a discussion amongst the participants of Task C was made on the basis of the previously provided information. This presentation reports the acquired data of the Horonobe EBS experiment over a ten-year period and the latest plan of the dismantling experiment.
