Topics

• Nuclear Regulatory Commission (NRC)

Regulations

• Discuss the oversight of the supply chain

• Observations identified during vendor inspection activities

• Questions 2

NRC Regulations

• 10 CFR Part 50, Appendix B, Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants

- Quality Assurance comprises all those planned and systematic actions necessary to provide adequate confidence that a structure, system, or component will perform satisfactorily in service

- Consists of 18 Criteria of Quality Assurance (QA) 3

NRC Regulations

• NRC evaluated Appendix B and ISO 9001-2000

• NRC issued the results of this analysis in SECY-03-0117 which is publicly available

• The attachment to SECY-03-0117 provides the details for the Appendix B to ISO 9001-2000 comparison.

NRC Regulations

• 10 CFR Part 21, Reporting Of Defects And Noncompliance

- Requires evaluation of deviations and failures to comply relating to defects that could create a substantial safety hazard

- Also prescribes the reporting requirements for defects or failures to comply

- Section 21.41, Inspection grants access for NRC inspections 5

NRC Regulations Other NRC Regulations that are applicable to NRC vendors:

• 10 CFR Part 50.5, Deliberate misconduct

• 10 CFR Part 50.7, Employee protection 6

Oversight of the supply chain

• NRCs Vendor Inspection Center of Expertise (COE) provides oversight of vendors supplying safety-related* parts, materials and services.

• Performs routine and reactive vendor inspections, as well as, quality assurance implementation inspections for new reactor applicants.

• safety-related as defined by 10 CFR 50.2 7

Oversight of the supply chain

• SECY-11-0154, Agencywide approach to Counterfeit, Fraudulent and Suspect Items, provide the following direction:

- The NRC staff will conduct vendor inspections at suppliers of safety-related Critical Digital Assets (CDAs), in accordance with 10 CFR Part 21

- The NRC staff will evaluate the results of these inspections to determine the need to expand the inspection sample to suppliers and sub-suppliers of non-safety-related CDAs 8

Oversight of the supply chain Vendor oversight of CDAs occurs if the items are procured as basic components (safety-related*)

- Appendix B and Part 21 requirements are contractually imposed on the vendor through the licensees procurement document

- These requirements are inspected by NRC using Inspection Procedure 43002

• safety-related as defined by 10 CFR 50.2 9

Oversight of the supply chain

• Inspection Procedure 43002, Routine Inspections of Nuclear Vendors

- Provides guidance to ensure NRC staff observes and assesses the vendors actual implementation to meet the licensee's contractual / procedural requirements 10

Vendor Inspection Observations

• Several licensee purchase orders to a vendor requiring:

- No harmful code or malicious logic: vendor shall have appropriate procedures in place to ensure that no viruses, malicious code or unintended code is transported into the production environment or the operational environment

• Vendor did not have a documented cyber security program in place to meet procurement document requirements 11

Vendor Inspection Observations

• Information Notice 2016-01 Allen Bradley Relays

- Manufacturer redesigned a relay to use a complex programmable logic device (CPLD)

- Use of a CPLD led to loss of safety function

- The plant was unaware of modifications to the basic component, so electromagnetic compatibility was not evaluated 12
