Isolation of spent nuclear fuel assemblies in deep vertical boreholes is analyzed. The main safety features the borehole concept are related to repository’s great depth, implying (a) long migration distances and correspondingly travel times, allowing radionuclides decay, (b) separation repository from dynamic hydrological cycle near land surface, (c) stable geological hydrogeological conditions...

The CBNG well water is typically managed by discharging into nearby disposal ponds. The CBNG well water could potentially be very useful in the water-limited regions (e.g., arid and semi-arid), but beneficial uses may be hindered by water quality problems. Objectives of this research were to: (1) examine trend analysis of nine years of CBNG well water at discharge (outfall) points and in corres...

A key challenge over the next decade for some national programmes and an important learning opportunity for many others will be the construction and operation of the first deep geological repositories for High Level Waste (HLW) and Spent Fuel (SF). As the orientation of work on disposal shifts from mainly research, development and demonstration to industrial implementation, waste management age...
