Most probabilistic assessments have tended to combine variability and parameter uncertainty, and not consider model or decision rule uncertainty. Recent guidance from the US National Academy of Sciences (NRC 1994), USEPA (1997), US DOE (Bechtel Jacobs Company 1998), and others (Hattis and Burmaster 1994 Hoffman and Hammonds 1994) has emphasized the importance of tracking variability and parameter uncertainty separately. Indeed, the USEPA (2000) states that the risk assessor should strive to distinguish between variability and uncertainty. Two major advantages of tracking variability and parameter uncertainty separately in an uncertainty analysis are...

Two waste streams were used in this study. Both were flaky materials, brown in color. The analysis of the first, provided by the sponsor, Bechtel Jacobs, showed a Tc level of 33,886 pCi/g (2020 ppm) and a U level of 107.05 pCi/g (40.1 ppm), with 233/234 j 23s j... 

To demonstrate this capabihty, Wagh et al. group worked with Bechtel Jacobs Co., the contractor at Oak Ridge, and conducted a feasibility study. The smdy comprised macroencapsulation of internally contaminated pipe sections [23]. 

Hazardous waste at ORNL generated by research and operational divisions is packaged, characterized and certified by the generating division supported by Laboratory Waste Services. Final certification is performed by the Laboratory Waste Services Organization in accordance with the current revision of die Waste Certification Program Plan. Disposition of hazardous wastes has been the responsibility of Bechtel-Jacobs Company, LLC and their subcontractors. In the near future, UT-Battelle will resume the responsibility for hazardous waste disposition.

After this introduction, ReVelle comments extensively on each of the subjects mentioned. He says Many companies—Honeywell, Dow Chemical, DuPont, General Electric (Health and Safety as well as Transportation Systems) and Bechtel Jacobs—have adopted six sigma as a primary focus in their efforts to reduce safety and health hazards. ReVelle also says that the role of black belts is largely that of specialists and as mentors, coaches, and teachers. In some companies...
