Objectives
- Overview of the NRC

- Overview of Inspection Program and Performance Indicators 2
What is the NRC ?
The NRC is an independent agency headed by five* Commissioners appointed by the President and confirmed by the Senate for staggered, five-year terms. One of them is designated by the President to be the Chairman and official spokesperson of the Commission.
The NRC is not associated with a federal department and does not report to a cabinet or secretary.
Who are the NRCs stakeholders?
Objective: Overview of NRC 3
History of the NRC Atomic Energy Act of 1946 created a government monopoly of nuclear technology and emphasized secrecy and weapons development. It established the Atomic Energy Commission (AEC).
Atomic Energy Act of 1954 ended the government monopoly and made the peaceful, commercial uses of nuclear technology an urgent priority. The AEC was then tasked with promoting and regulating peaceful applications of nuclear technology.
Energy Reorganization Act of 1974 separated the AEC into what became the DOE and the NRC. NRC began operation in 1975.
Follow-on legislation Objective: Overview of NRC 4
To license and regulate the nations civilian use of byproduct, source, and special nuclear materials to ensure adequate protection of public health and safety, promote the common defense and security, and protect the environment.
Objective: Overview of NRC 5

- Keep occupational dose to individual workers below the limits specified in 10 CFR Part 20 Subpart C and
- Use, to the extent practical, procedures and engineering controls based upon sound radiation protection principles to achieve occupational doses that are ALARA per (20.1101(b))
- To assess the performance of the radiological effluent control program

Types of Inspections Baseline inspections Supplemental inspections Generic safety issue, special and infrequent inspections Reactive Inspections (Management Directive 8.3, IMC 0309) 18 Objective: Overview of Inspection and PIs
Inspection Program Objectives To obtain factual information providing objective evidence that power reactor facilities are operated safely, and licensee activities do not pose an undue risk to public health and safety To determine the causes of declining performance before such performance reaches a level that may result in undue risk to public health and safety To identify those safety significant issues that may have generic applicability Baseline: provide sufficient examination, along with PIs, that licensees are meeting the objectives of the ROP cornerstones 19 Objective: Overview of Inspection and PIs
Regulations Design Basis Licensing Basis Licensing Process Licensee Performance Inspection Process Compliance Adequacy Other Agency Processes (e.g., assessment, generic issues)

Key Inspection Process Terminology Issue of Concern: A well-defined observation or collection of observations potentially impacting safety or security which may warrant further inspection, screening, evaluation or regulatory action Performance Deficiency: Licensees (1) failure to satisfy one or more regulatory requirements or self-imposed standards where such failure was (2) reasonably foreseeable and (3) preventable.
Inspection Finding: A performance deficiency determined to be more-than-minor Significance Determination Process: Process applied to a finding to determine its safety and security significance (i.e. Green, White, Yellow or Red)
Licensee-Identified: Identified as a result of deliberate observation by licensee personnel; and entered into licensee CAP 23 Objective: Overview of Inspection and PIs
Inspection Finding Process 24 Objective: Overview of Inspection and PIs
Is the PD More-Than-Minor?
If the answer to any of the following questions is yes, then the performance deficiency is More-than-Minor and is a finding.
- 1) Could the performance deficiency reasonably be viewed as a precursor to a significant event?
- 2) If left uncorrected, would the performance deficiency have the potential to lead to a more significant safety concern?
- 3) Is the performance deficiency associated with one of the cornerstone attributes and did the performance deficiency adversely affect the associated cornerstone objective?
Inspectors should also consider using IMC 0612, Appendix E, Examples of Minor Issues, when answering the screening questions listed above.

Inspection Readiness Tips Clearly state the problems and regulatory significance in condition reports if you understand it Be forthcoming on issues that arise during inspections Open communication with inspector onsite (when jobs are happening, pre-job briefings)
Contact your inspector if significant issues come up or issues where potential willfulness is involved Ensure program changes are thoroughly reviewed against FSAR, ODCM, and TRM requirements and perform adequate justification for changes Availability of program owners or subject matter experts during inspection 29 Objective: Overview of Inspection and PIs
