Facility Usage


Facility Statistics

The U.S. Department of Energy requires annual reports based on reporting requirements that address facility operations hours (which relate directly to data availability) and the number of users. The number of users includes site visitors as well as computer accounts of those requesting data. Safety and publication statistics are also being reported. Fiscal year (FY) represents October 1 to September 30. Beginning in FY2004, this information is provided for the entire facility as well as by individual site by FY in an annual report.

Below is a quick overview of the current numbers.
