APPROVED BY OMB: NO. 3150-0056 EXPIRES: 11/30/2023

Estimated burden per response to comply with this mandatory collection request: 360 hours. NRC is 

required to collect this information for reporting to IAEA from facility licensees appearing on the U.S. 

Eligible List. Send comments regarding burden estimate to the FOIA, Library, and Information 

Collections Branch (T-6 A10M), U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, 

or by e-mail to Infocollects.Resource@nrc.gov, and the OMB reviewer at: OMB Office of Information 

and Regulatory Affairs, (3150-0056), Attn: Desk Officer for the Nuclear Regulatory Commission, 725 

17th Street NW, Washington, DC 20503; e-mail: oira_submission@omb.eop.gov. The NRC may 

not conduct or sponsor, and a person is not required to respond to, a collection of information unless 

the document requesting or requiring the collection displays a currently valid OMB control number.

The purpose of this document is to 

obtain the facility design information 

required by the Agency in order to 

discharge its safeguards responsibilities. 

It will also serve as a checklist for 

examination of design information by 

Agency inspector(s). If, in any area, 

insufficient space is available add further 

shee ts to the extent necessary.
