Dear Mr. Kingsley:
SUBJECT:
NRC
I'NSPECTION
REPORT
NOS. 50-259/89-Ã,
50-260/89-16,
AND 50-296/89-16
This refers to the Nuclear Regulatory
Commission
(NRC) team inspection
led by
M. Branch during the weeks of November 27,
1989 and December ll, 1989.
The
inspection
included
a review of activities associated
with the preparation
for
startup of Browns Ferry Unit 2.
At the conclusion of the inspection,
the
findings were discussed
on December
20,
1989 with those
members of your staff
identified in the enclosed
inspection report.
The purpose of this in'spection
was to evaluate
the effectiveness
of the
corrective actions that have
been
conducted
to support Unit 2 'startup.
The
implementation of selected
portions of the
TVA Nuclear Performance
Plan
Volume
3 Corrective Action Programs that pertained
to the core spray system
was
evaluated.
The results of this inspection will be used to evaluate
the need
for additional
NRC activity in specifically identified areas.
This inspection
was
composed of design
and as-constructed
aspects.
Contact
was
maintained
between
inspectors
in ea'ch area
so that their respective efforts and
inspection findings were coordinated.
The design portions consisted of a.
selective
review of the core spray system design,
design bases,
and design
requirements.
The as-constructed
portion consisted of an in-plant review in
the mechanical, electrical, civil, structural,
and instrumentation
and control
disciplines in order to verify that the core spray system
as currently construc-
ted and installed is in accordance
with the licensed design basis
and applic-
able drawings.
In addition, the operational capability of the core spray
system
was evaluated
by reviewing the system operating instructions
and proce-
dures,
surveillance
and testing requirements,
corrective
and preventive main-
tenance activities,
and operator training.
The inspection
team evaluated,
on
a sampling basis,
portions of the
TVA Nuclear Performance
Plan functional
corrective action areas.
The
NRC team concluded that the core spray system
was functional, subject to
the scheduled
TVA modifications,
and that 'the design
was adequately
supported
by calculations.
Additionally, on the basis of the review of the core spray
system,
TVA appears
to be adequately
implementing your
NPP Volume
3 programs in
the following areas
to support Unit 2 startup.

(10) Contr actor Recommendations
In order to apply the results of this inspection to other systems
at Browns
Ferry,
TVA must ensure that the level of program completion
and system review
are not reduced.
The inspection findings indicate that certain activities appeared
to violate
NRC requirements.
The identified violations involved (I) ineffective correc-
tive action in the areas of calcu'1ations,
welding records,
and identification
of hardware deficiencies;
(2) failure to comply with drawing requirements
during initial hardware installation;
(3) failure to comply with plant proce-
dures;
and (4) inadequate
plant procedures.
The violations, references
to
pertinent requirements,
and elements
to be included in your response
are
described
in the enclosed
t
As discussed
during the exit, and during
a subsequent
phone conversation with
the Browns Ferry Site Director, the corrective actions for some of the viola-
tions should specifically address
the following areas:
(I)
Ensure that the
SPAE and
SPOC process,
'which is essential
in ensuring that
systems
are ready for operations,
continues
and that the walkdown portions
of the process
are strengthened.
(2)
Bound the scope of calculation problems identified by the team and ensure
they are resolved
on
a generic basis for all systems
covered
by your
Design Baseline
and Verification Program
(DBVP) calculation program.
(3)
Additionally, several
hardware-related
items were identified and
indicated that resolution of these
items would be deferred to resolution
of Unresolved Safety Issue
(USI) A-46, "Seismic gualification of Equipment
in Operating Plants."
The
NRC staff position on resolution of these
hardware
items
was discussed with your staff during the course of the
inspection
and again during the exit meeting.
Your response
should
address'ow
you plan to comply with the staff's position to ensure that
non-conforming hardware-related
items identified during your system
walkdowns are properly evaluated
and resolved.
Your response
should also specify
how you plan to address
the generic applica-
bility of the team's findings to other systems.
