Nuclear Regulatory Commission (NRC).


Notice of availability.


The NRC is issuing its Final Interim Staff Guidance (ISG) COL/ESP-ISG-004 (ML090060897). This ISG provides guidance regarding the definition of construction and the delineation of preconstruction activities and those activities requiring prior approval of the U.S. Nuclear Regulatory Commission (NRC or the Commission). In addition, this ISG provides guidance regarding the information to be submitted by any applicant for a limited work authorization (LWA).

The NRC staff issues ISGs to facilitate timely implementation of 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 COL/ESP-ISG-004 into the next revisions of the Regulatory Guide 1.206, “Combined License Applications for Nuclear Power Plants,” and related guidance documents.


The NRC maintains an Agencywide Documents Access and Management System (ADAMS), which provides text and image files of NRC's public documents. These documents may be accessed through the NRC's Public Electronic Reading Room on the Internet at​reading-rm/​adams.html. Persons who do not have access to ADAMS or who encounter problems in accessing the documents located in ADAMS should contact the NRC Public Document Room reference staff at 1-800-397-4209, 301-415-4737, or by e-mail at
