Announcement Notice (AN) 241.5 - Restricted Announcement of U.S. Department of Energy (DOE) Classified and Unclassified Controlled Nuclear Information (UCNI)

The Announcement Notice (AN) defines a set of metadata, including both required and optional, for use in describing Department of Energy's (DOE) Scientific and Technical Information (STI) products for announcement and availability.  An AN includes review and release information, enabling announcement and searchable online access as appropriate.  OSTI provides six different ANs for use by specified groups of submitters or in specified situations. 

The AN 241.5 provides the Office of Scientific and Technical Information (OSTI) with information required to appropriately identify, process, and/or announce, and disseminate the results of classified or unclassified controlled nuclear information (UCNI) work funded by DOE or performed in DOE facilities. Classified and UCNI STI products can be provided electronically or via paper copy in cases where an electronic copy is not available. Classified and UCNI STI products are to be submitted to OSTI through appropriate security/mail channels (through the Enterprise Secure Network (ESN) for secure online submission).
