What is the process for transmittal of security-related NRC generic communications to licensees?

The NRC's generic communications are typically transmitted to NRC materials licensees via e-mail, if provided, or mail using contact information stored in the NRC's Web-based Licensing (WBL) system.[1]  During the licensing process (i.e., applications for new licenses, amendments to existing licenses, or license renewals), NRC licensee contact information is recorded in WBL using information supplied by the licensee on the NRC Form 313, "Application for Materials License." 

How can I ensure that the appropriate licensee personnel responsible for implementing Part 37 physical protection requirements receive security-related NRC generic communications?

To ensure that the appropriate licensee personnel responsible for implementing Part 37 physical protection requirements receive NRC's generic communications, the NRC encourages NRC materials licensees to provide updates of contact information to the licensing team at the appropriate NRC regional office as listed on the NRC Form 313.  In the cases where the main licensee contact is not the individual responsible for implementing Part 37 physical protection requirements, it is expected that the licensee will distribute the generic communications to the appropriate personnel within their organization.

In addition, the NRC maintains an e-mail list server for electronic distribution of generic communications.  To subscribe to this list server, follow the instructions on the NRC Generic Communications Web site.  While subscribers to this list server will receive generic communications related to multiple disciplines (e.g., power reactors, materials, fuel cycle facilities), subscription to this list server can facilitate awareness of the availability of these communications, which, in turn, allows individuals and entities to identify and review correspondence of interest and relevance to their respective organizations and activities.

Who can I contact if I have a question or concern?

For any questions or comments related to any 10 CFR Part 37 topic, please send an email to Part37Resource@nrc.gov.

[1] WBL provides an up-to-date repository of all licenses authorizing the possession of Category 1 and Category 2 quantities of radioactive material nationwide.  WBL serves as the authoritative licensing system for all specific materials licenses issued by the NRC and thus contains all NRC-issued licenses authorizing the possession of Category 1, 2, 3, 4, and 5 quantities of radioactive material.  Agreement States may also choose to use WBL as their licensing system.
