SUBJECT:
BYRON INSPECTION REPORT 50-454/98011(DRP); 50-455/98011(DRP)_
Dear Mr. Kingsley:
On May 30,1998, the NRC completed an inspection at the Byron 1 and 2 reactor facilities. The
enclosed report presents the results of that inspection.
During the inspection period, we found that your evaluation of shutdown risk for planned activities
was thorough. We also noted that control room activities were consistently performed in a .
professional manner, in addition, we observed effective heightened level of awareness briefings,
strong reactivity management, and effective oversight by operations department management
and Quality and Safety Assessment personnel of infrequently performed . evolutions.
. However, we are concemed with the recurring problems in the implementation of the
{
out-of-service program. Since September 1997, you have repeatedly identified out-of-service
i
errors. We are concemed that to date, your corrective actions have not been effective to prevent
reoccurrence, as demonstrated by the out-of-service errors during the recently completed Unit 2
- refueling outage. These recent errors represent the failure of multiple barriers in the -
out-of-service program and ultimately placed personnel and equipment at risk.
In addition, we are concemed with the multiple examples of your failure to follow station
procedures. The most notable examples involved the failure to implement your ventilation barrier
- impairment process which, when combined with the failure to follow a maintenance procedure,
resulted in the facility being in a condition prohibited by Technical Specifications and outside the
ventilation design basis. Consequently, had an accident occurred while the ventilation system
g
was outside the design basis, the offsite dose and control room habitability dose would have
\\
been increased.
Based'on the results of this inspection, five violations of NRC requirements were identified. The
i
first ' violation involves a deficiency in the implementation of the out-of-service program. Although
the example was self-disclosing, a violation is being cited because this is a repetitive issue. The
second violation pertains to the failure to follow an operating procedure due to poor
communications practices. Although this violation was also self-disclosing, a violation is

being cited since you had not developed and committed to corrective actions prior to the end of
the inspection period. The third violation relates to four examples of your failure to implement the
ventilation barrier impairment process. The fourth violation involves the failure to follow a
.j
maintenance procedure regarding the control of penetration sleeves on the refueling water
!
storage tank pipe tunnel temporary hatch cover. The fifth violation pertains to your failure to
I
- update the Final Safety Analysis Report to include the effects of a safety evaluation in support of
a conclusion that the change did not involve an unreviewed safety question.
' These violations are cited in the enclosed Notice of Violation (Notice), and the circumstr.nces
surrounding the violations are described in detail in the enclosed report. Please note that you are
l
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 determina
whether further enforcement action is necessary to ensure compliance with regulatory
requirements.
in accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter, its
enclosures, and your response will be placed in the NRC Public Document Room.
' We will gladly discuss any questions you have conceming this inspection.
