Docket No. 50-455

ATTN: Mr. Cordell Reed
Senior Vice President
. Post Office Box 767
Chicago, IL 60690
Gentlemen:
This refers to the routine safety inspection conducted by Messrs.
P. G. Brochman, L. N. 01shan, G. L. Pirtle and Ms. N. V. Gilles of this
office from April 1 through May 17, 1989, of activities at Byron Station
Units 1 and 2, authorized.by NRC Operating Licenses No. NPF-37 and
No. NPF-66, and to the discussion of our findings with Mr. R. Ward and
others of your staff at the conclusion of the inspection.
cThe enclosed copy of our inspection report identifies areas examined during
the inspection. -Within these areas, the inspection consisted of a selective
examination of procedures and representative records, observations, and
l
' interviews with personnel.
No violations of NRC requirements were identified during the course of this
inspection. However, an event which is discussed in paragraph 4, and involves
. the physical inoperability of the 1A Diesel Generator (DG), is of concern to
the NRC. The NRC has evaluated this event and concluded that the
circumstances do not warrant the issuance of a Notice of Violation.
The NRC believes that your staff had taken reasonable precautions to ensure
that the DG should not have become inoperable during its painting. .However.
l
after the painting was completed, the decision not to perform a routine
I
surveillance, within at least 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, to ensure that the DG had in fact
remained operable, especially in light of the painting problem experiences
on the IB DG, was imprudent and non-conservative.
i
l
L
in accordance with 10 CFR 2.790 of the Commission's regulations, a copy of
this letter and the enclosure will be placed in the NRC Public Document Room.
