• Each dedicating entity should dedicate the services of each CB and should not rely on dedication by, e.g., another NRC licensee 7

Clarifications on NEI 17-06, Rev. 1 (2 of 3)

• In keeping with NRC staff-accepted practices, the CBs SIL certification process should be observed every 3 years

• In accordance with 10 CFR 21.3, the NRC use of the term basic component includes dedicated commercial grade items

Clarifications on NEI 17-06, Rev. 1 (3 of 3)

• The NRC staff is not endorsing the use of SIL certification by CBs that have not been accredited in conformance with IEC 61508

• Dedicating entities should verify that the substantive requirements of the later editions related to the dependability characteristics remain unchanged from the IEC 61508, 2.0 Edition
