ASME NQA
ASME NQA-1 (Nuclear Quality Assurance-1) is an industry consensus standard created and maintained by the American Society of Mechanical Engineers (ASME). The latest edition was issued on July 24, 2024 (NQA-1-2024). However, the most commonly used version in the supply chain is NQA-1-2008 with the NQA-1a-2009 addendum or newer. Any organization submitting an application for a new design may use up to the 2022 edition. This is the case because these are versions endorsed by the NRC.
