Abstract

Permeability at high temperature is a very important parameter to be considered for designing underground high level nuclear waste repository (HLW) in rock mass. The surrounding rock mass is exposed to heat radiated by HLW when it is buried underground and development or extension of micro-cracks takes place in the host rock due to rise in temperature. Keeping this in view, the permeability study was conducted for Charnokite rock at high temperatures in the range from room temperature, 30 to 200°C. The cylindrical rock samples of 36mm diameter and 150mm in length were used as per the required size for the equipment permeameter, TEMCO, USA. Total thirty rock samples were tested at various temperatures using nitrogen gas as fluid. The permeability tests were conducted at confining pressure of around 4MPa in order to simulate the horizontal in situ stress conditions in Charnokite rock at the depth of 400m for construction of HLW repository.
