Nuclear power plants operate under the most demanding maintenance compliance framework of any civilian industry. Under 10 CFR 50.65 — the NRC's Maintenance Rule — every licensed reactor must continuously monitor safety-critical structures, systems, and components against documented performance goals, and maintain records that can withstand an NRC inspection at any point in the operating cycle. A single missed preventive task on a safety-related system isn't a paperwork issue — it's a federal compliance event. For one operating nuclear plant, the combination of legacy record-keeping practices, disconnected SSC performance tracking, and a corrective action program running across separate tools created growing risk exposure heading into an 18-month NRC Reactor Oversight Process cycle. They deployed Oxmaint's 10 CFR 50.65-aligned CMMS and recorded zero NRC findings across the full cycle — the strongest compliance result in the plant's recent inspection history.

THE COMPLIANCE CONTEXT
What the NRC Maintenance Rule Actually Requires
10 CFR 50.65 requires every licensed nuclear power plant to monitor the performance and condition of SSCs against established performance goals — and to document, in auditor-ready form, how each component is trending against those goals. When an SSC fails to meet its goal, the plant must escalate to (a)(1) status and demonstrate active corrective actions. NRC Reactor Oversight Process inspections under IP 71111.12 review this entire documentation chain: goal establishment, performance tracking, (a)(1) escalation decisions, corrective action completion, and pre-maintenance risk assessments under (a)(4).
10 CFR 50.65(a)(1)
SSCs failing to meet performance goals must be placed in active monitoring status with documented corrective action plans reviewed by a qualified expert panel.
10 CFR 50.65(a)(2)
SSCs meeting goals must demonstrate performance is being monitored and goal attainment is documented on the required assessment cycle — typically annual.
10 CFR 50.65(a)(4)
Before performing maintenance, plants must assess and manage the increase in risk from taking SSCs out of service — with the assessment documented before work order release.
Appendix B / QA
Every maintenance activity affecting quality must be documented in records that are permanently retrievable, timestamped, and attributable to a qualified individual.
THE CHALLENGE
Where Documentation Risk Was Building
The plant's maintenance operations were competent. The engineers knew their SSC populations. Preventive maintenance was getting done. The problem was documentation integrity — the gap between what was happening in the field and what could be demonstrated to an NRC inspector.
A
SSC Performance Tracking in Disconnected Spreadsheets
Goal attainment status for 340 scoped SSCs was maintained manually in department-level Excel files. No central view. No automated alerts when components approached goal threshold. Engineers discovered (a)(1) candidates late.
B
Corrective Action Records Not Linked to Originating Findings
The corrective action program ran in a separate system from work order management. When NRC inspectors asked for the complete finding-to-closure chain on any (a)(1) component, staff had to manually reconstruct it across two systems — a process that took hours and introduced error risk.
C
Pre-Maintenance Risk Assessments Not Consistently Documented
10 CFR 50.65(a)(4) requires risk assessments before maintenance on in-scope SSCs. The assessments were being performed — but completion wasn't consistently recorded before work order release, creating an audit trail gap that (a)(4) inspections specifically target.
D
Annual Maintenance Rule Assessment Required Manual Aggregation
Producing the annual 10 CFR 50.65 program assessment report required pulling data from four sources, standardizing formats, and manually verifying completeness. The process took three weeks and was flagged internally as a significant error risk.

Is Your Plant's Maintenance Rule Documentation Ready for the Next NRC Inspection?
Oxmaint's nuclear CMMS delivers SSC performance monitoring, (a)(1) escalation workflows, pre-maintenance risk assessment gates, and one-click Maintenance Rule reports — built for 10 CFR 50.65 from the ground up.
THE SOLUTION
How Oxmaint Was Deployed Across 4 Weeks
The plant's maintenance rule coordinator led a four-week deployment using Oxmaint's nuclear-specific asset templates. No IT project sponsor. No multi-month configuration engagement. The system was live with safety SSC classifications, goal structures, and (a)(1)/(a)(2) monitoring dashboards operational before the start of the inspection cycle.
1
SSC Population Import & Safety Classification
All 340 scoped SSCs imported into Oxmaint with safety classification, maintenance rule scope designation, and established performance goals. Historical goal-attainment data migrated from department spreadsheets.
Days 1–7
2
PM Scheduling & Surveillance Test Configuration
All safety-related PM schedules and surveillance test intervals built into Oxmaint's scheduler. Auto-escalation rules configured to flag SSCs approaching (a)(1) threshold before goals are missed.
Days 8–14
3
(a)(4) Pre-Maintenance Risk Assessment Gate
Work order release workflow configured to require documented (a)(4) risk assessment completion before any in-scope SSC maintenance can be authorized. Assessment tied to work order record permanently.
Days 15–21

Corrective Action Integration & Annual Report Configuration
CAP workflow linked directly to SSC records. Annual Maintenance Rule assessment report template configured to auto-generate from live Oxmaint data — no manual aggregation required.

THE RESULTS
What the 18-Month Inspection Cycle Showed
NRC Reactor Oversight Process inspectors reviewed maintenance effectiveness under IP 71111.12 at the 9-month and 18-month marks. Both inspections closed with zero findings — a result that reflects documentation integrity as much as operational performance.
Zero
NRC Findings Issued Across Full 18-Month ROP Cycle
IP 71111.12 inspectors reviewed SSC goal documentation, (a)(1) population management, corrective action chains, and (a)(4) pre-maintenance records. Every request was answered from Oxmaint in real time — no reconstruction, no gaps, no findings.

SSCs flagged for early (a)(1) review before goals were missed — preventing reactive escalations during the inspection window
"The inspector asked us to pull the (a)(1) escalation history and corrective action records for three specific SSCs. We had everything — the goal data, the escalation decision, the CAP work orders, the re-assessment sign-offs — on screen in under two minutes. That's what a clean inspection looks like."

FREQUENTLY ASKED
Oxmaint for Nuclear Plant Maintenance Rule Compliance
How does Oxmaint handle the (a)(1) vs. (a)(2) SSC classification workflow?
Oxmaint monitors each SSC's performance against its established goal continuously. When a component approaches its threshold, the system flags it for engineering panel review before a goal is missed. If escalated to (a)(1), Oxmaint triggers a corrective action plan workflow and tracks re-assessment milestones. Learn more at
app.oxmaint.ai.
Can Oxmaint generate the annual 10 CFR 50.65 Maintenance Rule assessment report?
Yes. Oxmaint generates the annual assessment report directly from live plant data — goal performance summaries, (a)(1) population status, engineering panel findings, and program health metrics — structured for management review board or NRC submission. No manual aggregation required.
How long does Oxmaint deployment take at a nuclear plant?
Most plants complete initial deployment — SSC import, goal configuration, PM scheduling, and (a)(4) gate setup — within 4 weeks. The implementation is led by the plant's maintenance rule coordinator with Oxmaint onboarding support; no dedicated IT team is required.
Book a demo for a timeline walkthrough.
Does Oxmaint support ASME Section XI in-service inspection tracking?
Yes. Oxmaint supports ISI program tracking including 10-year interval milestone management, inspection percentage completion monitoring, and documentation of NRC relief request records — alongside Maintenance Rule and Appendix B quality records in a single platform.
What does Oxmaint cost for a nuclear plant?
Oxmaint is available at subscription pricing scaled to plant size and SSC population — structured for operations and maintenance budgets, not enterprise IT budgets.
