RESPONSE TO NOTICE OF VIOLATION 50-458/8627-02
LEVEL IV
REFERENCE
Notice of Violation - J. E. Gagliardo letter to W. J. Cahill, Jr.
dated
October 24, 1986.
Request for additional information - J. E. Gagliardo letter to W. J.
Cahill, Jr. dated December 22, 1986.
FAILURE TO FOLLOW A SURVEILLANCE TEST PACKAGE
REASON FOR THE VIOLATION
,
a
When performing Surveillance Test Procedure
(STP)-203-1102, " Battery
Weekly Surveillance Test for 1E22*S001 BAT", the procedure requires the
technician to obtain and record the pilot cell numbers using the
i
previous
performance
of
STP-203-1302,
"1E22*S001 BAT
Quarterly l
Surveillance Test".
The pilot cells are defined as the cells having the
lowest specific gravities.
When obtaining the pilot cell numbers the
.
performer is required to identify and select the lowest cell readings
!
from a four (4) page tabulation of values. During the performance of
the quarterly test on August
12,
1986,
maintenance
personnel
.
inadvertently recorded the cell number having the lowest specific
..
gravity (cell #37) and the cell with the third lowest specific gravity
(cell #52).
This personnel oversight resulted in a deviation from the
procedural requirements of STP-203-1102.
I
CORRECTIVE STEPS WHICH HAVE BEEN TAKEN AND THE RESULTS ACHIEVED
f
Immediately upon discovering the error of identifying the incorrect
i
pilot cell number, a conservative approach was takan, and 'the batteries
!
were removed from service. STP-203-1102 was rerun on September 12, 1986
with satisfactory results.
Following the performance of STP-203-1102 on September 12, 1986, the
data recorded by the procedure since the
last
performance
of
STP-203-1302 (Quarterly Test), was reviewed to ensure compliance with
r
(
River Bend Technical Specifications and IEEE 450-1975.
The review
concluded that the data recorded met the intent of IEEE 450-1975 and was
within the limits specified by the Technical Specifications.
While performing the history review of the data recorded during the
performances of STP-203-1102, it was discovered that STP-203-1102
performed on August 18, 1986 also failed to identify the correct pilot
cell numbers.
This was caused by personnel not having available the
latest performance of STP-203-1302 (Quarterly Test) when obtaining the
l
pilot cell numbers.

ATTACHMENT (Cont'd.)
To ensure these problems are not indicative of a generic problem, the
Maintenance Department conducted a review
of
other
Maintenance
Surveillance Test Procedures that require data to be transferred from
another source.
The review identified some Radiation
Monitoring
Calibration Surveillance Procedures and Instrumentation Response Time
Procedures as also requiring the transfer of data.
,
It has been concluded that the Radiation Monitoring Surveillance
Procedures provide sufficien't methods and controls to preclude the
transfer of incorrect data.
These procedures
require
Radiation
Protection to provide Maintenance with background radiation readings and
source count values. Unlike the Battery Surveillance Procedures, the
Radiation Monitoring Procedures involve a separate discipline for the
purpose of verifying the data, and the values being transferred are
readily identifiable.
On
November
7,
1986,
CR
86-1708
was
initiated identifying
Instrumentation Response Time
Procedures
having
incorrect
data
transferred
during
their
initial
performance.
An Engineering
investigation of this condition revealed no response time was found to
exceed the Technical Specification response time acceptance criteria.
The CR identified programmatic problems in a number of areas which
contributed to the incorrect data being transferred.
As documented on Condition Report (CR) 86-1809 during a review of leak
rate
data
from
STP-208-3600,
" Main
Steam
Positive
Leakage
Control / Penetration Valve Leakage Control System Leakage Rate Test", it
was discovered that the wrong value was used to compile Division 1 Main
Steam Positive Leakage Control System Leakage Rate. Two tests were
performed to determine inboard main steam isolation valve B21*A0VF022C
inleakage rate.
One test was performed on November 11, 1986 and
indicated 174.45 standard cubic feet per hour (SCFH), while another test
performed on November 12, 1986 indicated 201.4 SCFH. The value recorded
on test dated November 11, 1986 was used to determine total inleakage
rate.
However the test dated November 12, 1986 should have been used
because it was the last test performed on this valve. Data transfer was
determined to be the cause.
I
Leak rate data was analyzed by a number of different methods. In each
approach, leakage of B21*A0VF022C satisfied Technical Specification
criteria. New STP-208-3600 data is being compiled and will be completed
by February, 16, 1987.

the latest Quarterly Battery Test on file until the next performance of
the test. Upon completion of the next scheduled quarterly battery test
of the results of the previous quarterly test will be transmitted to the
Permanent Plant File (PPF).
Remaining STP's will be reviewed for possible transfer of data concerns.
These reviews will be document'ed, problems identified, corrections made
and procedures revised by July 1, 1987, to prevent recurrence of data
transfer errors.
DATE FULL COMPLIANCE WILL BE ACHIEVED
The affected Battery Surveillance Test Procedures have been revised.

~
LEVEL IV
REFERENCE
Notice of Violation - J. E. Gagliardo letter to W. J. Cahill, Jr.
dated October 24, 1986.
FAILURE TO FOLLOW A SURVEILLANCE TEST PACKAGE
REASON FOR THE VIOLATION
When
performing
Surveillance
Test
Procedure
(STP)-203-1102,
" Battery
Weekly
Surveillance
Test
for
IE22*S001 BAT",
the
procedure
requires the technician to obtain and record the pilot
cell numbers using
the
previous
performance
of
STP-203-1320,
"1E22*S001 BAT
Quarterly Surveillance Test".
The pilot cells are
defined as the cells having the lowest specific gravities.
When
obtaining the pilot cell numbers following the performance of the
quarterly
test
on
August
12,
1986,
maintenance
personnel
inadvertently recorded the cell number having the lowest specific
gravity (cell #37) and the cell with the
third
lowest
specific
gravity
(cell
- 52).
This
personnel
oversight
resulted in a
deviation of the procedural requirements of STP-203-1102.
CORRECTIVE STEPS WHICH HAVE BEEN TAKEN AND THE RESULTS ACHIEVED
l
Immediately
upon
discovering
the
error
of
identifying
the
l
incorrect
pilot
cell
number, a conservative approach was taken
and the batteries were removed from
service.
STP-203-1102 was
rerun on September 12, 1986 with satisfactory results.
Following
the performance of STP-203-1102 on September 12, 1986,
the data recorded by the procedure since the last performance
of
STP-203-1320
(Quarterly Test), was reviewed to ensure compliance
with River Bend Technical Specifications and IEEE 450-1975.
The
review
concluded
that
the data recorded met the intent of IEEE 450-1975 and was within the limits
specified
by
the
Technical
Specifications.
While
performing
the history review of the data recorded during
the
performances
of
STP-203-1102,
it
was
discovered
that
STP-203-1102 performed on August 18, 1986 also failed to identify
the correct pilot cell numbers.
This was caused by personnel not
,
having
available
the
latest
performance
of
STP-203-1302
l
(Quarterly Test) when obtaining the pilot cell numbers.
