This refers toithe. Nuclear Regulatory Commission (NRC) inspection conducted by
l
G. L. Paulk .on March 1
. April 30,1987. The inspection included 'a review of
l
activities authorized for your Browns Ferry-facility. At the conclusion of.the
"
inspection, .the findings were discussed. with . those members' of .your staff -
R
identified'in-the enclosed inspection report.
1
Areas examined during the inspection included operational safety, maintenance
obshnation,
surveillance
testing
cbservation,
reportable ' occurrences,
configuration management, Restart Review Board and the Independent Safety.
L
Engineering Group '(ISEG) activity, welding modifications, the lay up program,
and low' pressure turbine disc cracking,
Within these : areas, the inspection consisted. of selective examinations of
I
procedures and representative- records,
interviews with personnel,. and
observation of activities in progress.
.
!
The inspection findings indicate certain activities appeared to violate NRC
requirements.
The violation involved an : inoperable Control Room Emergency
Ventilation'(CREV) System.
The violation, references to pertinent require-
ments, and elements to be included in your response are described in the
!
enclosed Notice of Violation (NOV). For the first example of the enclosed NOV,
!
I
please ' address your reasons and corrective actions regarding the timeliness
a'spect of identifying . the actual low flow condition on the B train CREV
system.
Your attention .is. called to paragraph 7, Surveillance Testing observation,
where the Browns Ferry (BFN) quality assurance staff recently performed a
technical review of the BFN Surveillance Instructions (SI). The intent was to
i
.' review ten percent of the 430 sis but was temporarily halted after about five
percent because it was concluded that the existing technical adequacy review
program was inadequate. A condition adverse to quality report was written and
the SI program was halted.
More management involvement in the implementation
of this p_rogram will be required to assure satisfactory completion of the
. program.

Engineering Group (ISEG)' staffing level at BFN.
As described in the BFN
Nuclear Performance _. Plan,: Volume 3, dated August 28, _1986, ..the BFN ISEG would
consist of three full-time engineers onsite.
NUREG 0737, Item I.B.1.2 speci-
fies that the ISEG should be comprised of a minimum of five dedicated, full-
time engineers.
However, a number less than five may be acceptable, but must
be_ justified'on a case-by-case basis. Our concern.is that based on our current
knowledge _of :the qualifications you intend to use in filling. the BFN ISEG
.
positions, the experience level 'does not appear to justify going to fewer
l
4
than five members. Since the ISEG staffing issue was also. raised in our_ review
of the BFN' Nuclear Performance Plan, you should ensure that your revision to
)
Volume 3' addresses this question.
