Apply Safeguards Information marking and reproduction controls to every copy

Frame this document as a source-led configuration and assurance check: Apply Safeguards Information marking and reproduction controls to every copy. Only the official source and traced locations below supply facts. Confirm applicability before acting.

Source fact:

The official 10 CFR 73.22 – Protection of Safeguards Information: Specific requirements from U.S. Nuclear Regulatory Commission via eCFR supports the following bounded statements:

• Under 10 CFR 73, documents or other matter containing Safeguards Information, when transmitted outside an authorized place of use or storage, must be packaged in two sealed envelopes or wrappers to preclude disclosure of the presence of protected information. The research record locates this support at 10 CFR 73.22(f)(1) (eCFR anchor p-73.22(f)(1)).
• Under 10 CFR 73, safeguards Information may be reproduced to the minimum extent necessary consistent with need without permission of the originator. The research record locates this support at 10 CFR 73.22(e) (eCFR anchor p-73.22(e)).

Do not import neighboring assumptions into the source record. The supported task is a scoped comparison involving access control, video, intrusion detection, communications, supporting facilities, operators, and documented response paths and the conditions the source actually describes.

What the source does not establish

NRC regulation governing protected information; the brief must avoid reproducing protected operational details and must be reviewed by authorized security and legal personnel. A correct source interpretation can still be inapplicable to a particular design. Confirm identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel, ownership, and change authority instead of treating documented behavior as a deployment guarantee.

Applicability questions

• For source statement 1 at 10 CFR 73.22(f)(1) (eCFR anchor p-73.22(f)(1)), which observable configuration, record, or test can confirm applicability here?
• For source statement 2 at 10 CFR 73.22(e) (eCFR anchor p-73.22(e)), which observable configuration, record, or test can confirm applicability here?
• Which deployed instance of access control, video, intrusion detection, communications, supporting facilities, operators, and documented response paths will be compared with the source, and why that instance?
• How will the review distinguish a source mismatch from a failure in identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel?
• Who approves the conclusion, exception, test window, and rollback threshold?

DSE recommendation:

DSE recommends using the cited source as the evidence anchor for this decision. Use a two-person review for the source interpretation and the resulting operational decision. Record the source location, examined part of access control, video, intrusion detection, communications, supporting facilities, operators, and documented response paths, observed and expected states, owner, and reason for deviation.

If the review warrants change, use a bounded implementation with prerequisites, test population, monitoring, abort criteria, and a rehearsed reversal. Sequence checks for identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel and sanitize protected material before retention.

Verification and evidence

Build a reproducible chain from 10 CFR 73.22(f)(1) (eCFR anchor p-73.22(f)(1)); 10 CFR 73.22(e) (eCFR anchor p-73.22(e)) to the observed environment. Useful domain evidence includes asset and firmware inventories, configuration exports, event tests, inspections, alarm response records, and maintenance findings; label every item with scope, timestamp, collector, and stable identifier.

Preserve both successful and failed observations, along with approval and rollback evidence. Avoid uncontrolled production experiments. Assign an expiry or event-driven recheck so the conclusion is not treated as permanent.
