SUBJECT:
NRC INTEGRATED INSPECTION REPORT 50 327/96 09 AND 50-328/96-09
Dear Mr. Kingsley:
On September 14, 1996, the NRC completed an inspection at your Sequoyah
facility. The enclosed report presents the results of that inspection.
During the period covered by this inspection period, your conduct of
activities at the Sequoyah facility was generally characterized by acceptable
operations, engineering, maintenance practices, and radiological work
{
controls. We are concerned, however, about a violation of NRC requirements
that was identified. Corrective actions, associated with the emergency diesel
generator (EDG) starting air compressor pre;sure control switch failures, were
considered to be untimely and inadequate.
In addition, the root cause
determinations for the 1995 and initial 1996 problems were considered to be
weak in that they failed to identify the defective EDG compressor pressure
switches.
We are also concerned that repetitive equipment problems continued to cause
added operator burden ard impacted maintenance resources, operation's
switching and tagging resources, and da) to day operations.
Problems with
plant material condition indicate weaknesses in maintenance and engineering
,
support.
This violation is cited in the enclosed Notice of Violation (Notice), and the
circumstances surrounding the violation are described in detail in the
enclosed report.
Please note that you are required to respond to this letter
and should follow the instructions specified in the enclosed Notice when
preparing your response. The NRC will use your response, in part, to deter-
mine whether further enforcement action is necessary to ensure compliance with
regulatory requirements.
