POWER Tool - Planning, Optimization, Waste Estimating and Resourcing tool, a hand-
held field estimating unit and relational database software tool for optimizing disassembly
and final waste form of contaminated systems and equipment.
The U.S. Department of Energy must deactivate and dismantle dozens of major facilities that are
highly contaminated as a result of past weapons production activities. Each facility
dismantlement will cost hundreds of millions of dollars and will generate large amounts of
waste. Decisions on approach and sequencing for dismantling these facilities will be a major
factor in the ultimate cost. There is an urgent need for a tool to help the technical staff of these
facilities estimate the work needed and waste generated, perform case comparisons, and develop
an optimized plan that can save tens of millions of dollars for each major facility.
Task Structure and Sequencing
A task structure and sequencing was developed to systematically estimate and plan the
decontamination, dismantlement and waste disposal for contaminated systems. The structure
lends itself to consideration of alternative methods that optimize between important attributes
including; labor cost, waste disposal, and schedule. Different cases can be estimated to explore
the effect of alternate work approaches, and the best tradeoff selected as the baseline for the
Database Tool, Field Estimating Unit
The POWER Tool software is used for field estimating on a
small hand-held PC about the size of a videocassette and
weighing less than 2 pounds. An adapter and neck strap has
been designed to allow the unit to hang comfortably around the
estimator's neck when not in use. The unit contains a high- ,
resolution color screen, a keyboard and pointing device for data
entry. A high-capacity lithium-ion battery allows field
operation for 3 to 4 hours before a battery change is required.
Data is recorded on a flash-RAM card in the PCMCIA card slot in Fig. 1 Hand held PC
