The study of the sealing system of high level radioactive waste repository (Part2)

Abstract

  In geological disposal, it is necessary to prevent shaft, tunnel and their environs to be a main passage of radioactive nuclide transfer by sealing system combined backfill, plug and grout. This paper shows an example of design of sealing system. Since calcium ion from concrete tunnel support is considered to change the property of sealing material, the effect of concrete is evaluated by experimental study.
