Nuclear power use is expected to expand in the future and result in hundreds of thousands of metric tons of spent nuclear fuel (SNF). One of the main concerns of nuclear energy use is SNF disposal. Storage in geological repositories is a reasonable solution for the accumulation of SNF. One of the key factors that determine the performance of the pr...

Fiber optics can directly detect cracks if they form within the path of a fiber optic as well as monitor secondary indicators of cracking such a...
Over time, nuclear waste packages disposed in geological repositories are expected to fail gradually due to localized and general corrosion. As a result, water will have access to the nuclear waste and radionuclides will be transported to the accessible environment by ground water. In this paper we consider a serious failure case in which penetrati...
Nuclear power use is expected to expand in the future, as part of the global clean energy initiative, to meet the world's surging energy demand, and attenuate greenhouse gas emissions, which are mainly caused by fossil fuels.

Sodium-chloride brine underlies the shallow subsurface and discharges in springs and streams at numerous locations in Kent and Stonewall Counties in Central Texas. These discharges eventually flow into the Salt Fork of the Brazos River, lowering the quality of this important surface water resource. One potentially cost effective solution for the pr...
One of the most important concerns related to the use of nuclear energy is the disposal of nuclear waste. Geologic repositories are convenient options for permanent disposal of highly radioactive waste. They are technically feasible, protect the environment in the short and long term, and allow spent fuel retrieval for future reprocessing. The repo...
Natural tributaries in arid regions are generally ephemeral occurring only during the generally short and isolated thunderstorms. Thus, sustained flow is rare and baseflow is essentially absent, large volumes of surface runoff water move into the channel within a short period causing flash floods that are characteristic of arid-zone drainage basins...
