Environmental
problems of national importance are considered under the topic
"environmental analysis" in TSA-4. In particular, nuclear
waste legacy problems fill the greater portion of the projects
that have been historically funded, although certain other problems
of national importance (e.g., increase of pollutants in the Salton
Sea) can be of interest if they fit our background and capabilities.
These problems are analyzed using a
variety of methodologies: economic analyses, technology evaluations,
modeling and simulation, and complex-wide workshops to look at
modeling and simulation techniques for environmental waste cleanup.
Probably the longest-running project TSA-4 has held under this
category is ETCAP (Environmental Technology Cost-Savings Analysis
Project), which has over 100 publications and continuous funding
since 1990.
