SUMMARY
Scope:
This routine,
unannounced
inspection
was conducted in the areas
of material control and accountability.
Results:
In the areas
inspected,
violations or deviations
were not
identified.
One open item was closed which was reported in NRC

Followup On Corrective Actions For Previous Violations
and/or Deviations
(92702)
NRC Inspection Report Nos. 50-259/91-33,
50-260/91-33,
and
50-296/91-33 resulted in escalated
enforcement action as
referenced
in NRC Enforcement Action (EA)91-120.
EA 91-120
documented
a violation involving the licensee's
failure to
perform an adequate
physical inventory of special nuclear
material
(SNM) in 1990.
Specifically, the February
and
March 1990 physical inventories failed to include an item
containing
SNM, which was identified in the spent fuel pool
on September
7,
1991.
(CLOSED) Violation 50-259/91-33,
50-260/91-33,
and
50-296/91-33.
Failure To Perform An Adequate Physical
Inventory Of Special Nuclear Material.
The inspector
examined the licensee's
programmatic
. improvements
and specific corrective actions
and determined
the following:
TVA revised four procedures for ensuring:
(1) Plant
management is involved in daily activities of storing
radioactive material in the Spent Fuel Storage
Pools
(SFSPs),
(2) Low-Power Range Monitors
(LPRM) are
properly stored in one piece,
and
(3) the
SFSPs
are
expeditiously cleaned
up after an outage.
Procedure
0-GOI-100-3
was revised to address
the Plant Manager'
responsibility for activities in the SFSPs.
Additionally, this procedure
was revised to warn
personnel that
SFSPs
are not to be. used for long-term
storage of radioactive material
and that
a yearly
inventory be 'performed using a form requiring the Plant
Manager's signature.
Special Instrument Instruction 0-XX-92-051 Revision 6,
was revised to remove steps
which allowed
LPRMs to be
cut upon removal from the reactor cavity.
The current
revision requires the
LPRM to remain intact thereby
avoiding confusion of whether or not an
LPRM string
contains
a "hot"
(SNM) end or not.
Without cutting the
(when they are removed from the cavity) should
prevent small "hot" LPRM pieces to be stored in
different locations in a
SFSP thereby potentially
losincf future inventory accountability.
Finally,
Radwaste Instruction RWI-116 was revised to allow LPRMs
to be cut only at the time they are being packaged for
disposal.
The three
SFSPs
were vacuumed to clear silt and small
debris from the
SFSP floors.
The silt contributed to
the oversight of SNM during the previous two inventory
phases.
A camera
was used to assist in the floor
cleanup locating small material for disposal.
Irradiated waste
was removed from the SFSPs.
Additionally, all non-essential
radioactive material
was removed from the SFSPs.
A final inventory was performed
and a current listing
has
been developed to establish
a current and accurate
base-line
inventory.
TVA hired an outside consultant to perform an
independent
assessment
of the
This assessment
investigated the following areas:
procedures,
personnel,
SNM accountability,
storage
areas
and containers,
records,
and control of
calibration sources.
The assessment
included
interviews with selected
licensee
employees,
document
evaluation,
records accuracy,
and extensive plant
tours.
The contractor
assessment
entitled "Browns Ferry
Nuclear Plant Special Nuclear Material Control Program
Assessment,"
dated
May 11,
1992,
concluded that there
is a heightened
awareness
of the
SNM Control Program
including its requirements
and responsibilities
throughout the entire
BFN organization.

Based
on this inspection followup.review, the inspector
concluded that the completion of all phases
of the original
SNM baseline
inventory program along with the completion of
the additional corrective actions
above, that appropriate
steps
have been taken and an adequate
program now exists to
prevent recurrence
of a similar violation.

Nuclear Material Balance Reports
The inspector
examined the licensee's
Material Balance
Reports
(DOE/NRC Form 742) issued under Rep'orting
.Identification Symbols
XDP (Unit 1),
XFY (Unit 2),
and
XJD
(Unit 3) for the period ending March 31,
1992.
This
examination
was to determine whether the reports accurately
reflected quantities of fuel and non-fuel
SNM received
and
shipped
and whether uranium depletion
and plutonium
production had been entered.
The inspector determined that
the report was completed
and distributed in accordance
with
the printed instruction in NUREG/BR-0007 and the recorded
data were found to be in agreement with associated
accountability records.
Exit Interview
The inspection
scope
and results
were summarized
on July 22,
1992, with those persons
indicated in Paragraph
1.
The
inspector described
the areas
inspected
and discussed
in
detail the inspection results.
Although reviewed during
this inspection,
proprietary information is not contained in
this report.
Dissenting
comments
were not received
from
the licensee.
The licensee
was advised
by the inspector that no further
reports to the
NRC are required relative to the close-out
action on the violation referenced in NRC Inspection Report
Nos. 50-259/91-33,
50-260/91-33,
50-296/91-33,
and/or
EA 91-120.
