Is the licensee address on NRC Form 748 or in NSTS the “mailing address” or “location of use” address?
The “location of use” address as authorized on the license is the licensee address for reporting in the NSTS. The NSTS Federal Register Notice for the NSTS Final Rule (65686 FR 71) clarifies that licensees will provide the actual address (location of a facility) when reporting source transactions to the NSTS. In addition, NRC Form 748 (11-2008) provides guidance that the address should be where the source is used or stored. For completeness, the NSTS provides fields for both the “mailing address” and locations of use authorized on the license that are selectable from a drop down list when reporting transactions online.
