This refers to the Nuclear Regulatory Commission (NRC) routine resident
t
inspection conducted by K. M. Jenison on May 6 - June 12, 1987. The inspection
included a review of activities authorized for your Sequoyah facility. At the
conclusion of the inspection, the findings were discussed with those members of
your staff identified in the enclosed inspection report. NRC concerns relative
to the inspection findings associated with control of operational activities
were discussed by J. A. Axelrad, Deputy Director, Office of Special Projects
(OSP) and G. G. Zech, Assistant Director, Inspection Programs, Division- of TVA

-
ference is contained in paragraph 16 of the enclosed inspection report.
Areas examined - during the inspection are identified in the report.
These
areas included special reviews of licensee groups performing safety review
functions, the Sequoyah Restart Testing Program, recent reactor coolant system
spill events,
and functional testing.
Within these areas, the inspection
consisted of selective examinations of procedures and representative records,
interviews with personnel, and observation of activities in progress.
The inspection findings indicate that certain activities appeared to violate
NRC requirements.
Violation 50-327,328/87-30-02 concerns the failure of. the
. Nuclear Safety Review Board to perform its review function as specified in
Technical Specifications.
Violation 50-327,328/87-30-07 concerns specific
examples of where procedures were not properly established and implemented.
Accordingly, these two violations, references to pertinent requirements,. and
' elements to.be included in your response are described in the enclosed Notice
of Violation.
An additional- violation (50-327,328/87-30-01) was also identified and is
discussed in paragraphs 9,15 and 16 of the enclosed inspection report. This
multiple example violation involves inadequate procedure implementation which
has given cause for concern over your staff's control of Sequoyah's operational
activities, particularly in the areas of system and equipment status and
testing.

consequences of the violation.
In addition, resubmit TVA's response to
