It can be downloaded from the link below: As these systems age and become obsolete, utility companies are beginning to incorporate digital technology due to its proven record of high reliability in other industries, as well as wide spread availability. Published by Elsevier Ltd. In Option Epei, the OEM manufactures commercial parts that are readily available outside of the nuclear industry and the commercial parts go through a final acceptance process when they are ordered as a nuclear safety related part.
This is a great question epdi it can be very difficult to find requirements for commercial grade dedication.

Download NRC Letter here. Abstract Instrumentation, control and monitoring systems in operating nuclear power plants generally utilize analog technology.
If your company manufactures commercial parts and sells the same parts to the nuclear industry as safety related parts, do those parts have to go through Commercial Grade Dedication?
You can always perform full CGD of the items, but this guidance allows the OEM to perform an acceptance process that is appropriate based on the advantages that the OEM has in regards to controlling the drawings and commercial process and receiving additional feedback from commercial uses of the fpri.

EPRI NP has been revised to make it easier to follow for the performance of commercial grade dedication. Commercial grade dedication is called into existence by 10CFR21both in the definitions and section These include items such as evaluating the effects of electromagnetic and radio frequency interference on the system reliability, the need for software verification and validation, the review of abnormal conditions and events analysis ACEsas well as overall licensing aspects and the need to increase use of commercial-grade equipment to decrease cost, particularly for safety systems.
Keywords Nuclear power stations. The first question received is: As a side note, if a quality program follows NQA-1, the section for Basic Requirement 7 includes requirements for Commercial Grade Dedication which differ based on the edition followed. The process is complete when all critical characteristics are verified and the item is designated for use as a basic component. Download full text in PDF Download.
