Simplifying How to Manage 10 CFR 50.69 Categorization and Compliance

Implementing 10 CFR 50.69 can be challenging when doing so with manual processes and tools. In this blog post, we highlight how technology can simplify the process from categorization to reassessment.

March 27, 2026

About 75% of safety-related components are expected to be categorized as low safety significant, per the Nuclear Energy Institute.

With 10 CFR 50.69, plants can categorize structures, systems, and components based on their safety significance. The resulting improved efficiency occurs while nuclear plants maintain rigor required by the regulation to grow a consistent and defensible categorization basis.

Implementing 10 CFR 50.69 can be challenging when doing so with manual processes and tools. It can feel like a tall order for your teams to pull the data together to identify where you can save in costs related to special treatment and testing requirements.

Using technology specifically designed for 50.69 compliance, it can simplify the process and bring significant cost savings to the organization. A tool designed for 50.69 compliance can:

  • Make it easier to categorize structures, systems, and components (SSCs)
  • Improve operational efficiency while maintaining the strict required by the regulation
  • Better prioritize condition-based maintenance with RISC categorizations

However, today’s nuclear plants find that the biggest benefit comes from the potential cost savings that plants can experience with using a solution to support 10 CFR 50.69 compliance implementation.

Systematize Your RISC Categorizations

RISC categorizations are not only a necessary part of 10 CFR 50.69 compliance, but they offer support to maintenance teams beyond meeting the requirements.

As the Nuclear Energy Institute indicated, with three out of four safety components falling as low safety insignificant, it means that you can focus maintenance efforts on the components with the greatest safety significance. Using this system can reduce the need to complete special treatment and testing requirements for low safety significant items, which results in cost savings for plants – both from personnel and for materials.

A purpose-built tool, like Endevor’s platform, that allows systematic categorization for components from RISC-1 to RISC-4 serves as the first step in building a comprehensive program that aligns with 10 CFR 50.69 compliance.

To fully support the dynamic needs of plants, the tool should be able to categorize the components either site by site, or system by system.

Get Data to Build Maintenance Priorities

As with many of today’s maintenance activities for nuclear plants, data is the engine behind effective 10 CFR 50.69 compliance. Easy-to-access probabilistic risk assessment (PRA) data means you can better prioritize condition-based maintenance.

When you use accurate, data-backed RISC categorizations, they can inform exactly where you can optimize treatment, testing, and inspection intervals. This supports smarter and more cost-effective asset management from the core.

In addition, it frees up time for maintenance teams so they can focus on components with the greatest safety significance.

Reduce Procurement and Maintenance Costs

By combining defensible data and structured, regular assessments, your engineering team gets essential insight to understand which components and systems qualify for alternative treatment approaches.

Categorization based on risk frees up budget beyond the maintenance team. Procuring parts becomes more cost-effective, as 10 CFR 50 Appendix B requirements no longer apply for low safety significant parts. The cost for the parts becomes more economical, and the lead time for ordering the parts becomes more favorable.

Freeing up resources and budgets that were tied to RISC-3 and RISC-4 parts and components means that programs can then re-focus it on the assets that carry the highest risk for operations. 

Maintain a Digital Record for All Categorization Decisions

Compliance is only as strong as your documentation. To simplify regulatory reporting and minimize compliance risk, it requires that plants must maintain complete digital records of all categorization decisions.

Moving to a software solution that effectively manages categorization simplifies how teams meet the documentation requirement. Gone are multiple spreadsheets, binders, and files that create an array of information. Enter granular visibility into how you define key functions, as well as the how structures, systems, and components are categorized within the plant.

The result? Easily support ongoing 50.69 compliance and reassessment while minimizing compliance risk and simplify regulatory reporting. 

Prepare for Reassessment

Because 10 CRF 50.69 compliance requires ongoing management, plants must continuously monitor performance. This may require updates to the risk models – which can be a headache to maintain (especially if relying on manual methods).

Plant configurations will change. Your PRA models will update. New equipment failure data will emerge. All of these factors, as well as any others deemed relevant, have potential to shift categorization over time.

Using a single software solution simplifies how to manage mandatory reassessments. Centralized data makes it easy to manage a streamlined workflow to make, track, and report on any changes.

And, when a modification occurs that impacts RISC-3 components, it simplifies how they are flagged in the system for review and re-evaluated to determine the appropriate categorization. As a result, the categorization basis remains defensible while being tracked, managed, and reported upon.

Endevor’s Solution for 10 CFR 50.69 Compliance

To effectively optimize your categorization for your structures, systems, and components, it requires visibility into your data. The Endevor Strategy product includes a 50.69 module to get a deeper, and more comprehensive view, into what’s happening across your assets – right down to the component level.

With Endevor’s solution, build a master equipment list so you can:

  • Reduce the time, hassle, and potential delays of the 50.69 reassessment cycle
  • Shift from costly, labor-intensive manual processes to a cost-effective digital solution
  • Empower your organization to stay ahead of the regulatory curve with the ability to make informed decisions

Advancing your 10 CFR 50.69 compliance starts by effectively categorizing your structures, systems, and components. RISC categorizations help inform where treatment, testing, and inspection intervals can be optimized. PRA data better prioritizes condition-based maintenance.

With all data related to 10 CFR 50.69 tracked in one system, the complete digital records related to categorization become a strategic advantage while simplifying the process to categorize and maintain compliance. Strategic 50.69 categorization doesn’t have to be a manual burden.
