NQA-1 Nuclear Quality Assurance for Tennessee Manufacturers

NQA-1 is the ASME standard for nuclear quality assurance — formally titled Quality Assurance Requirements for Nuclear Facility Applications. It establishes the quality program requirements that organizations must meet when supplying safety-related products or services to nuclear facilities. The standard is structured around the 18 quality assurance criteria in NRC 10 CFR 50 Appendix B, making it the primary way the nuclear industry demonstrates compliance with federal nuclear quality regulations. It covers all phases of nuclear facility life — from design and procurement through construction, operation, and decommissioning.

Any manufacturer supplying safety-related products or services to a nuclear facility. This includes component and parts manufacturers, material suppliers, fabricators, testing and inspection service providers, and engineering firms whose work is classified as safety-related scope by the nuclear customer. Nuclear power plant operators, DOE national laboratories, and SMR developers all require their safety-related suppliers to operate under an NQA-1-compliant quality program. It also applies to organizations entering the nuclear supply chain for the first time who need to demonstrate QA program compliance to win their first nuclear contract.

The Tennessee MEP support process follows three phases:

Phase 1 — Explore & Evaluate: Structured gap assessment against NQA-1 Part I and Part II requirements. Identifies what your current quality program has, what is missing, and what the path to compliance looks like before you commit to anything.

Phase 2 — Build & Implement: Development of your Quality Assurance Program documentation, procedures, controls, and records aligned to NQA-1 requirements. Includes process mapping, internal auditor training, and preparation for customer or third-party audits.

Phase 3 — Maintain & Sustain: Independent internal audits, corrective action support, interim audit preparation, and ongoing program maintenance to keep your NQA-1 program current and audit-ready.

Not for safety-related nuclear work. ISO 9001 is a general quality management standard that does not satisfy the nuclear-specific requirements of NRC 10 CFR 50 Appendix B. NQA-1 is purpose-built for the nuclear industry and addresses controls that ISO 9001 does not — commercial grade dedication, nuclear-specific procurement controls, traceability requirements, and the 18 defined criteria for nuclear quality programs. That said, ISO 9001 is an excellent foundation. Manufacturers with an existing ISO 9001 system have the documentation discipline and process structure already in place, which significantly reduces the effort required to build an NQA-1-compliant program on top of it.

Most manufacturers complete the process in 9 to 18 months, but the timeline is driven by more than documentation. Two requirements add mandatory time that cannot be compressed regardless of how fast the program is built.

Mandatory operational run period: Before a customer or third-party audit can take place, your quality program must have been fully operational for a minimum of three months and must have completed a full cycle of internal audits and a management review. Documentation alone does not satisfy this — the program has to be running and generating records.

Internal auditor qualification: NQA-1 has specific requirements for lead auditor certification — including completion of an NQA-1 Lead Auditor training course and participation in five qualifying audits, at least one of which must be nuclear. Building this capability internally takes time and has to be planned early in the process.

Starting point matters: Manufacturers with an existing ISO 9001 system typically land in the 9 to 12 month range because the documentation framework and process discipline carry over. Manufacturers starting from scratch should plan for 12 to 18 months. Tennessee MEP will give you a realistic projection before you commit to anything.

Typical milestone sequence: Gap Assessment → QA Program Development → Procedure Documentation → Internal Auditor Training → Program Operational Run → Internal Audit → Management Review → Customer or Third-Party Audit → Audit Remediation.
