SUBJECT:
BYRON INSPECTION REPORT 50-454/98017(DRP); 50-455/98017(DRP)

Dear Mr. Kingsley:
On August 24,1998, the NRC completed an inspection at the Byron 1 and 2 reactor facilities.
The enclosed report presents the results of that inspection.
During this inspection period, we noted that control room activities were consistently performed
in a professional manner. This was most evident by your response to the Unit i loss of offsite
power event. We observed effective oversight by operations department management and
strong command and control throughout the event recovery.
However, we are concemed with the trend in configuration control events. Since
!
January 1998, you have identified numerous examples of failure to maintain control of the
configuration of plant systems and equipment, most of which involved nonsafety-related
balance of plant systems and did not result in adverse safety consequences. While we
recognize that you are in the process of developing a comprehensive corrective action plan to
address the issue, we are concemed that to date, your corrective actions have not been
effective at arresting the trend of configuration control events.
'
One violation of NRC requirements was identified during this inspection period. This violation
involves the failure to maintain the main control room ventilation envelope configuration due to
inadequacies in your ventilation barrier impairment process. The violation is cited in the
enclosed Notice of Violation (Notice) and the circumstances surrounding it are described in
detailin the enclosed report. The NRC has concluded that information regarding the reason
for the violation,- the corrective actions taken and planned to correct the violation and prevent
recurrence is already adequately addressed on the docket in Licensee Event Report (LER)
-t
50-454/98016, dated August 6,1998. Therefore, you are not required to respond to this letter
'
unless the description therein does not accurately reflect your corrective actions or your
t
- position. In that case, or if you choose to provide additionalinformation, you should follow the
instructions specified in the enclosed Notice.
