SOUTHWEST RESEARCH INSTITUTE, SAN ANTONIO, TEXAS, USA

Senior Research Scientist 03/02 to 04/06
Research Scientist 06/98 to 03/02

Performed independent research to support characterization of the hydrogeologic system in the vicinity of Yucca Mountain , Nevada . This work was performed to support the US Nuclear Regulatory Commission (NRC) review of the impending US Department of Energy’s (DOE) licence application to operate a high-level waste repository at Yucca Mountain .

Recently appointed Principal Investigator on a team studying the effects of future repository heating on the movement of water in and around repository drifts. The quantity and chemistry of groundwater entering drifts can accelerate the degradation of engineered barriers at the repository. The annual budget for the project is approximately USD $800,000.

 Responsibilities include:

  • Performing independent research on the thermal hydrology of the repository site
  • Coordinating the research activities of the group
  • Preparing the annual Operations Plan for the group
  • Communicating the activities of the group and related items of interest (including DOE activities) to senior management and the client

Member of a team conducting research to better characterize the movement of groundwater flow in the saturated zone in the vicinity of Yucca Mountain , Nevada . The saturated groundwater flow system is one potential pathway along which radio nuclides breaching the engineered barrier system at the repository may reach the accessible environment.

Achievements include:

  • Coordinated the development of a hydro-geophysical program to support characterization of the geology and hydrology along the projected groundwater flow path. Results of this characterization activity will lead to improved predictions of the (i) groundwater flow path from the site and (ii) radionuclide transport times. Both are important for assessing the performance of the repository.
