Senior Vice-President
Post Office Box 767

,
Gentlemen:
'
This refers' to the routine safety inspection conducted by Mr. R.. A. Hasse,
Ms. A. M. Bongiovanni, and Ms. V. P. Lougheed of. this office on February 27
through March 16, 1989, of activities at Byron Nuclear Power Station, Units li
'
and.2 authorized by NRC Operating Licenses No. NPF-37 and NPF-66 and to the
discussion of our findings with Mr. R. Pleniewicz and others of your staff
at t~ne conclusion of the inspection.
The purpose of this inspection was to determine if design changes and
modifications and the dedication of commercial grade equipment for
,
safety-related applications were being conducted in accordance with
'
regulatory ~ requirements. Within these areas, the inspection consisted
!
of a selective examination of procedures and representative records,
observations, and interviews with personnel.-
The results of this inspection indicated some weaknesses in the areas of design
control and post modification testing.
It appeared that this was due, in part,
,
'to a weakness in communications between the large number of organizations
involved in the design change process.
Several examples of problems noted
i
were:
failure to seismically qualify several valves installed in a
j
modification to MSIV accumulator test connections; failure to convey critical
i
preventative maintenance requirements for diesel general governor circuit
relays; and, failure to fully test a modification installing a time delay
relay.in the auxiliary feedwater pump trip logic.
We were also concerned with the apparent lack of understanding of the intent
of 10 CFR Part 50, Section 50.59 and the lack of a well-structured program
,
for dedicating commercial grade equipment for safety-related applications.
,
We were encouraged by our review of several recent audits performed by your
quality assurance organizations in that they had identified several concerns
similar to'those identified during this inspection. This indicates that your
audit program is effective in identifying problems.
