SUBJECT:
BYRON INSPECTION REPORT 50-454/99003(DRP); 50-455/99003(DRP)
Dear Mr. Kingsley:
1
1
On March 29,1999, the NRC completed an inspection at the Byron 1 and 2 reactor facilities.
The enclosed repori presents the results of that inspection.
During this inspection period, control room operations were performed in a safe and
professional manner. Operators adhered to the station's standards for reactivity management,
l
professionalism, control room conduct, procedural adherence, annunciator response, and
l
generally used three-way communication This observation has been consistent over the past
l
severalinspection periods. We also noted that the conduct of maintenance was generally
performed well, with two notable exceptions. The first example, which the inspectors identified,
resulted in the improper installation of flexible hoses on the Unit 1 A emergency diesel generator
and the second example resulted in the over-torquing of coupling fasteners on the Unit 1 A
chemical and volume control pump couplings. In both of these examples, mechanical
maintenance first-line supervisors improperly changed the work instructions which caused the
,
l
deficiencies.
i
We continue to be concerned with configuration control and human performance errors at
l
Byron Station. Following three incidents during the second week of March 1999, you conducted
a 10-day stand down period beginning on March 11,1999, to focus on performance standards.
Two of those incidents are addressed in this report. In the first incident, the Unit 1 A emergency
diesel generator was rendered inoperable for approximately 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> while the north door to the
1 A diesel oil storage tank room was left open and unattended. The second incident involved a
potential chemical transfer accident, in which sodium hydroxide was nearly transferred from a
delivery truck into a storage tank containing sulfuric acid. While we recognize that you are
aggressively implementing corrective actions to address configuration control and human
performance events, the effectiveness of your actions has yet to bo demonstrated.
Based on the results of this inspection, the NRC has determined that five violations of NRC
requirements occurred. Thesc /iolations are being treated as Non-Cited Violations (NCVs),
consistent with Appendix C of the Enforcement Policy. These NCVs are described in the
subject inspection report. If you contest any of the violations or the severity level of these
NCVs, you should provide a response within 30 days of the date of this inspection report, with

On February 5,1999, Byron Station implemented Amendment No.106 to the Technical
Specifications (TS). The amendment reflects the full conversion of the TS to a set of Improved
Technical Specifications (ITS) based on NUREG-1431, " Standard Technical Specifications --
Westinghouse Plants," Revision 1, dated April 1995. Inasmuch as some of the violations
discussed in the enclosed report occurred prior to ITS implementation, reference is made to
applicable sections of the TS as they existed prior to ITS implementation for those violations.
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter, its
enclosure and your response, if you choose to provide one, will be placed in the NRC Public
Document Room.
We will gladly discuss any questions you have concerning this inspection.
Sincerely,
