Introduction to NQA-1:2022

The ASME Nuclear Quality Assurance (NQA-1) Certification Program reflects industry experience and understanding of QA requirements while providing centralized, independent, third-party certification for quality assurance programs in conformance with the ASME NQA-1:2022 standard, “Quality Assurance Requirements for Nuclear Facility Applications”.

Part I of the NQA-1 Standard provides requirements that prescribe the extent of controls needed in specific areas of a nuclear quality program (an ASME NQA program).

Part II contains supplemental quality assurance requirements – specifically, how to perform specific activities under a program developed to Part I.

Additionally, Parts III and IV of the Standard provide non-mandatory subparts that contain further guidance and more in-depth discussion on certain aspects (e.g., commercial grade dedication).

Which Companies or Industries Does This Standard Apply To?

The ASME NQA-1 Certification Program seeks to meet the needs of the nuclear industry by expanding the supply chain with organizations who are committed to understanding quality and providing high quality products and services to nuclear facilities.

Examples of nuclear facilities can include nuclear power plants (NPP), small modular reactors (SMR), microreactors, and advanced reactors, and the handling of radioactive and/or fissionable materials for fuel processing, and fuel recycling.

What are the benefits of being certified in this standard?

The NQA-1 Quality Program Certificate is available to organizations implementing the ASME NQA-1 Standard, Part I and Part II, or portions thereof. An NQA-1 Quality Program Certificate is not available to an organization for activities pertaining to weaponry and for Owners of facilities handling and/or utilizing nuclear material.

Certification Process

The NQA-1 certification process is a systematic approach that organizations follow to demonstrate their commitment to quality, efficiency, and compliance with international standards.

NQA certification adheres to the following steps:



Initial certification audit

Stage 1

Stage 2


Companies often hire expert consultants to simplify the NQA-1 certification process and reduce the burden on existing management teams in leaning new standards, ensuring compliance, developing documentation and more. This makes it more cost effective for companies to hire consultants to support them through the process than pursuing it on their own.

Quality Systems Enhancement is the only company that offers guaranteed certification through our 10-Step Approach™ to ISO (or any) certification. QSE ISO consultants emphasize developing simplified, documented Management Systems which meet or exceed the requirements of any ISO standard requirements. This 10-Step Approach™ has a built-in discipline to involve all employees, including top management, right from the beginning to achieve long-term, desired results. Our approach is so complete that we have helped over 800 companies obtain certification, of which, the majority have obtained certification with zero deficiencies.
