Coordinate physical protection for irradiated reactor fuel in transit

Use this document to resolve one bounded operational decision: Coordinate physical protection for irradiated reactor fuel in transit. Only the official source and traced locations below supply facts. Confirm applicability before acting.

Source fact:

The official 10 CFR 73.37 – Irradiated reactor fuel in transit from U.S. Nuclear Regulatory Commission via eCFR supports the following bounded statements:

• Under 10 CFR 73, a licensee must protect spent-fuel transit Safeguards Information under sections 73.21 and 73.22, including information about defensive tactics and capabilities. The research record locates this support at 10 CFR 73.37(b)(1)(viii)(H), read with 10 CFR 73.37(b)(1)(viii)|73.37(b)(1) (eCFR anchor p-73.37(b)(1)(viii)(H)).
• Under 10 CFR 73, a movement control center must be continuously staffed by someone authorized to monitor the shipment and coordinate physical-protection activities. The research record locates this support at 10 CFR 73.37(b)(3)(ii) (eCFR anchor p-73.37(b)(3)(ii)).

These statements are the factual basis for this document. Do not extend them into a broader assurance. Review access control, video, intrusion detection, communications, supporting facilities, operators, and documented response paths only where the source and recorded environment align.

What the source does not establish

NRC regulation for covered shipments; security plans, routes, schedules, escorts, communications, and response details can be sensitive and require authorized review. It does not establish a deployment’s current state, authorize a production change, prove compliance, or show that identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel are healthy. Documented options are review inputs, not universal mandates.

Applicability questions

• For source statement 1 at 10 CFR 73.37(b)(1)(viii)(H), read with 10 CFR 73.37(b)(1)(viii)|73.37(b)(1) (eCFR anchor p-73.37(b)(1)(viii)(H)), which observable configuration, record, or test can confirm applicability here?
• For source statement 2 at 10 CFR 73.37(b)(3)(ii) (eCFR anchor p-73.37(b)(3)(ii)), which observable configuration, record, or test can confirm applicability here?
• Which owner can attest to the recorded state of access control, video, intrusion detection, communications, supporting facilities, operators, and documented response paths, including exceptions?
• What baseline for identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel must accompany the source-specific observation?
• Which success, stop, and escalation criteria are written before testing begins?

DSE recommendation:

DSE recommends using the cited source as the evidence anchor for this decision. Start with applicability, then compare the observed state with the cited source. 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.

For an approved change, define prerequisites, a limited test path, success and stop conditions, monitoring, and rollback. Check identity, Windows DNS where used, time, networks, power, life-safety systems, vendors, and monitoring personnel in design order. Protect credentials, keys, recovery material, personal data, and sensitive topology in evidence.

Verification and evidence

A reviewer should be able to retrace the decision from 10 CFR 73.37(b)(1)(viii)(H), read with 10 CFR 73.37(b)(1)(viii)|73.37(b)(1) (eCFR anchor p-73.37(b)(1)(viii)(H)); 10 CFR 73.37(b)(3)(ii) (eCFR anchor p-73.37(b)(3)(ii)) through asset and firmware inventories, configuration exports, event tests, inspections, alarm response records, and maintenance findings. Record what was collected, where, when, by whom, and which system or role it represents.

Close the review only when the evidence, exception handling, resulting action, and after-state are linked. Schedule a new review after material technical, organizational, incident, or source changes; today’s observation is not a continuing guarantee.
