Information Notice No. 90-13:  IMPORTANCE OF REVIEW AND ANALYSIS OF 
                                   SAFEGUARDS EVENT LOGS 


Addressees:

All holders of operating licenses or construction permits for nuclear power 
reactors.  

Purpose:

This information notice is intended to remind addressees of the benefits of 
meaningful reviews and analyses of the safeguards event logs and reports 
required by 10 CFR 73.71, and of initiating prompt, effective corrective 
measures to prevent recurrence of identified problems.  It is expected that 
recipients will review the information for applicability to their facilities 
and consider actions, as appropriate, to avoid similar problems.  However, 
suggestions contained in this information notice do not constitute NRC 
requirements; therefore, no specific action or written response is required.

Description of Circumstances: 

During recent inspections of safeguards event logs and associated reports, 
the NRC staff found numerous repeated violations of requirements and 
commitments in safeguards programs.  These violations showed that effective 
corrective action had not been taken by the licensees.  The licensees 
generally categorized, totaled, and reported event information but did not 
analyze it to identify developing problem areas and did not take effective 
corrective action to prevent recurrence of problems.  One utility identified 
numerous violations of its physical security plans at several facilities but 
did not implement effective action to preclude recurrence of similar 
violations.  The violations included over 20 examples of improper 
notification upon termination of employees, over 30 examples of security 
equipment that was operated in a degraded condition or was accessed without 
proper compensatory measures, and over 40 examples of personnel being issued 
incorrect unescorted access badges.  These violations resulted in a Notice 
of Violation and Proposed Imposition of Civil Penalty.

Discussion:

The identification of developing trends and the analysis of root causes of 
these trends are important aspects of the process for determining whether

there are any vulnerabilities that may adversely affect the protection of 
the public health and safety.  The safeguards event log is intended to be, 
and has been for some licensees, an effective management tool to identify 
problem areas and to determine and monitor the effectiveness of corrective 
measures to preclude recurrence of identified problems.
