Waste Treatment Plant Seismic Project Making Progress

November 2006
ETD's Brent Barnett, Bruce Bjornstad, Tom Brouns, Steve Reidel, Alan Rohay and Anna Schultz share credit for the successful drilling of four new boreholes at DOE's Waste Treatment Plant (WTP) a month ahead of schedule. The PNNL team is providing DOE technical leadership and project management for the engineering and construction of the WTP. The $18M project was an essential step in reducing uncertainty in the current seismic design criteria, and downhole seismic testing can now begin. A final report, due to DOE in April 2007, will include direct measurements of shear-wave velocities in the basalts and sediments below the facility.
