From page 6...
... The TWRS SRR, conducted by a high-level DOE headquarters team, found many deficiencies with the practice of systems engineering at the Hanford Site. The review has led to substantial changes in the TWRS management approach as described in the TWRS SRR Action Plan (U.S.

... , in which the preferred alternative is one in which all single-shell and double-shell tanks would be subject ultimately to the same waste removal goal, 99 percent. Consideration of remediation alternatives for nearby soils contaminated by tank leakage and past waste management is deferred to a future EIS, as is disposition of the tanks themselves and residual contents.

... The result is a decoupling of strategies for reducing the risks posed by the tank wastes from consideration of the risks posed by residual contamination left in the tanks and surrounding soils once the tank contents have been removed.

... A recent letter to the committee from the current contractor, Lockheed Martin Hanford Corporation, states that "we have made substantial progress employing systems engineering principles to develop a technically defensible and integrated baseline for TWRS" (Boston, 1998~. The Hanford Site Systems Engineering Implementing Directive provides a broad systems-level view of the Hanford site-wide remediation problem (Figure 3~.

... An early version of what was then referred to as the Hanford Site Systems Engineering Management Plan (Westinghouse Hanford Company, 1994) contains the document hierarchy description shown in Figure 5.

... The schedules imposed by the TPA may also operate to constrain trade studies. Milestone M-33 in the Hanford TPA, for example, makes the negotiated dates for TWRS retrieval, treatment, and final closure into major TWRS milestones.

... Programmatic risk management procedures contained in the Hanford TWRS and Site Systems Engineering Management Plans, if implemented as proposed, and if implemented effectively, should remedy weaknesses that have been identified by earlier NRC reviews and by the TWRS Systems Requirements Review.
