SUBJECT: SAFETY SYSTEM FUNCTIONAL INSPECTION REPORT 50-313/86-01
This letter forwards the report of the Safety System Functional Inspection
perfomed by an NRC team over the period January 6-31, 1986 involving
activities authorized by NRC Operating License Number DPR-51 for the
Arkansas Huclear One-Unit I facility. This inspection was conducted
jointly by members of Region II, Region IV, the Office of Inspection
and Enforcement, and NRC contractors. At the conclusion of the inspection,
the findings were discussed at an exit meeting with those members of your
staff identified in the appendix to the enclosed inspection report.
This NRC effort at Arkansas Nuclear One represents a new inspection approach
involving an assessment of the operational readiness and functionality of
selected safety systems. Particular attention is directed to the details
of modifications and design control, quality of maintenance and surveillance,
and adequacy of testing applicable to those safety systems. At ANO, the team
selected the f.ergency feedwater (EFW) system as the primary focus of its review.
The report includes findings that may result in enforcement action, which
would be the subject of subsequent correspondence. The report also addresses
other observations and conclusions made by the inspection team.Section II
of the report is a summary of the safety effects of the more significant
findings on the operational readiness of the selected safety system.
In general, the inspection team fcund the design of the AN0-Unit 1 EFW system to
be sound; however, several aspects of your programs for modifying, testing, and
maintaining this system were considered to be deficient. The inspection team
identified significant cor.cerns in the areas of mechanical design changes and
modifications, seismic interaction, torque switch settings of motor-operated
valves, and testing of EFW system components. We request that you respond to
this office within 45 days describing the actions that you have taken or intend
to take to improve management controls over the specific licensed activities
described in Section II of this report as significant findings.
In the area of
motor-operated valves, consideration should be given to providing an expedited

response to IE Bulletin 85-03.
In the area of testing EFW system components,
consideration should be given to conducting a comprehensive review of the
adequacy of the test programs covering EFW system components at ANO-1.
While planning corrective actions based on the weaknesses identified in the
enclosed report, it is important that you realize that the focus of this
inspection was only on the emergency feedwater system at AN0-1.
Therefore ,
consideration should be given to identifying and correcting similar problems
in other safety-related systems.
Should you have any questions concerning this inspection, we would be pleased
to discuss them with you.
Sincerely,
J/me +s M. Tay1
