SUMMARY: The NRC is issuing its Final Interim Staff Guidance (ISG) DC/

the current staff guidance and to facilitate activities associated with 
review of applications for early site permits and combined licenses for 
the Office of New Reactors. The NRC staff will also incorporate DC/COL-
ISG-007 into the next revisions of the Regulatory Guide 1.206, 
``Combined License Applications for Nuclear Power Plants,'' and related 
guidance documents.
