CommercialGradeDedicationGuidance.pdfCommercial Grade Dedication (CGD) is an acceptance process performed in accordance with NQA-1 to provide reasonable assurance that an item or service will successfully perform its intended safety function and, in this respect, is deemed equivalent to an item or service provided under the requirements of NQA-1. A facility procuring an item or service that supports a nuclear safety function has two options to procure the item or service. The item or service must be either procured or performed subject to the requirements of ASME NQA-1 (appropriate addenda) Part I and II or be commercial grade dedicated in accordance with the requirements of ASME NQA-1 (appropriate addenda). Joseph Oat has an NQA-1 and 10CFR50 App. B program that allows us to commercially dedicate those items that cannot be purchased as NQA-1.

The process of commercially dedicating an item requires an in-depth understanding and knowledge of purpose and function of the item to be dedicated. A part can be as simple as a piece of plate or more complex assembly such as a filter body. Joseph Oat has an industry approved CGD procedure in place that provides clear direction as to how to CGD an item or assembly at Joseph Oat
