| [Summary] |
 By
applying centrifugal acceleration to a small model ground, this equipment enables
to generate the same phenomenon as occured in the actual ground by reproducing
the same stress state as the actual ground in the model and to shorten the duration
of phenomenon such as consolidation. The machine specification is an effective
radius of 1.36 m and the maximum centrifugal acceleration of 200 g. This machine
is characterized by the replacement of slip rings during operation, resulting
in loing-term continuous operation. Geo environmental problems include settlement
of overpack in the geological disposal of high-level radioactive wastes, long-term
mechanical behavior of the surrounding foundation and leakage of harmful substances
from industry waste disposal sites. This machine will clarify and assess long-term
behaviors of structures and foundations. |

| [Objective] |
For high-level radioactive waste disposal, it is
necessary to predict and evaluate the buffer's behavior and mechanical properties
over the order of thousands to tens of thousands of years. Time limitations require
scaled- down time tests and it is essential to reproduce of the actual stress
at the foundation. This machine was constructed to satisfy both these requirements.

| [Specification] |
1) Main body is beam type equipment with an effective
rotation radius of 1360 mm.
2) Delivery maximum centrifugal acceleration is 200 g at a static state.
3) It has a platform loading capacity of 100 kg.
4) Four channels are provided for the slip ring for heavy electric current and
24 channels are for the slip ring for weak electric current, both of which can
be replaced during operation (long-term continuous operation).
