Nuclear Safety Culture in the Latest U.S. Report for the Convention on Nuclear Safety

NUREG-1650 cover
The Nuclear Regulatory Commission (NRC) recently published NUREG-1650, rev. 6, the seventh national report for the Convention on Nuclear Safety.*  The report is prepared for the triennial meeting of the Convention and describes the policies, laws, practices and other activities utilized by the U.S. to meet its international obligations and ensure the safety of its commercial nuclear power plants.  Nuclear Safety Culture (NSC) is one of the topics discussed in the report.  This post highlights NSC changes (new items and updates) from the sixth report (NUREG-1650, rev. 5) which we reviewed on March 26, 2014.  The numbers shown below are section numbers in the current report.

8.1.5  International Responsibilities and Activities 


The NRC’s International Regulatory Development Partnership (IRDP) program supports the safe introduction of nuclear power in “new entrant” countries.  IRDP training addresses many topics including safety culture. (p. 99)

8.1.6.2  Human Resources 


This section was updated to include a reference to the 2015 NRC Safety Culture and Climate Survey.

10.1  Background [for article 10, “Priority to Safety”] 


The report notes “All U.S. nuclear power plants have committed to conducting a safety culture self-assessment every 2 years and have committed to conducting monitoring panels as described in Nuclear Energy Institute (NEI) 09-07, “Fostering a Healthy Nuclear Safety Culture,” dated March 2014.” (p. 120)  We reviewed NEI 09-07 on Jan. 6, 2011.

10.4  Safety Culture

The bulk of the report addressing NSC is in this section and exhibits a significant rewrite from the previous report.  Some of the changes reorganized existing material but there are also new items, discussed below, and additional background information.  Overall, section 10.4 is more complete and lucid than its predecessor.

10.4.1  Safety Culture Policy Statement

This contains material that formerly appeared under 10.4 and has been expanded to include two new safety culture traits, “questioning attitude” and “decisionmaking.”  The NRC worked with licensees and other stakeholders to develop a common language for discussing and assessing NSC; this effort resulted in NUREG-2165, “Safety Culture Common Language.”  We reviewed NUREG-2165 on April 6, 2014.

10.4.2  NRC Monitoring of Licensee Safety Culture 


This section has been edited to improve clarity and completeness, and provide more specific references to applicable procedures.  For example, IP 95003 now includes detailed guidance for NRC inspectors who conduct an independent assessment of licensee NSC.**

New language specifies interventions the NRC may take with respect to licensee NSC: “These activities range from requesting the licensee perform a safety culture self-assessment to a meeting between senior NRC managers and a licensee’s Board of Directors to discuss licensee performance issues and actions to address persistent and continuing safety culture cross-cutting issues.” (p. 128)

10.4.3 The NRC Safety Culture

This section covers the NRC’s efforts to maintain and enhance its own SC.  The section has been rewritten and strengthened throughout.  It discusses the need for continuous improvement and says “Complacency lends itself to a degradation in safety culture when new information and historical lessons are not processed and used to enhance the NRC and its regulatory products.” (p. 130)  That’s true; SC that is not actively maintained will invariably decay.

12.3.5  Human Factors Information System 


This system handles human performance information extracted from NRC inspection and licensee event reports.  The report notes “the database is being updated to include data with a safety culture perspective.” (p. 146)

Institute of Nuclear Power Operations (INPO)

INPO also provides content for the report, basically a description of INPO’s activities to ensure plant safety.  Their discussion includes a section on SC, which is not materially different from their contribution to the previous version of the report.

Our Perspective

Like the sixth national report, this seventh report appears to cover every aspect of the NRC’s operations but does not present any new information.  In other words, it’s a good reference document.

The NSC changes are incremental but move toward increased bureaucratization and intrusive oversight of NSC.  The NRC is certainly showing the hilt of the sword of regulation if not the blade.  We still believe if it reads like a set of requirements, results in enforceable interventions and quacks like the NRC, it’s de facto regulation.
