This document presents the vision for Brookhaven National Laboratory (BNL) for the next five years, and a roadmap for implementing that vision. Brookhaven is a multidisciplinary science-based laboratory operated for the U.S. Department of Energy (DOE), supported primarily by programs sponsored by the DOE's Office of Science. As the third-largest funding agency for science in the U.S., one of the DOE's goals is ''to advance basic research and the instruments of science that are the foundations for DOE's applied missions, a base for U.S. technology innovation, and a source of remarkable insights into our physical and biological world, and the nature of matter and energy'' (DOE Office of Science Strategic Plan, 2000 http://www.osti.gov/portfolio/science.htm). BNL shapes its vision according to this plan.

This document describes two tasks that support CH2M Hill Hanford Group's (CHG) Mission Acceleration Initiative (MAI) testing and demonstration/deployment of supplemental technologies, but the tasks are not to be part of the vendor's scope. The vendor's will be provided samples of radioactive waste for their testing. This document describes the preparation of the radioactive waste samples. CHG is responsible to retrieve the saltcake waste from the single-shell tanks and expects to dissolve the waste using water dissolution. When water dissolves the waste the more soluble components of the waste (including cesium) will dissolve first, leaving the lesser soluble components of the waste in the tank. This phenomenon, termed selective dissolution, is expected to provide a partial separation of cesium from the waste. This document also describes a program involving tank dissolution demonstrations, modeling, and laboratory testing to more completely understand how the composition of the retrieved salt cake waste will change during the course of retrieval.
