Gentlemen:
Thank you for your letter of_ April 25, 1989, in response to our' letter and the
attached Notice of Violation dated March 28, 1989. As a result of our review,
we find that additional information is needed, as discussed with your Mr. Don
-Lomax during a telephone call with our Messrs. W. Seidle and R. Azua on May 17,
1989.
Specifically, in the area of corrective steps, which will be taken to
avoid further violations, it was noted that all of the corrective steps needed
to preclude recurrence of valve misalignments associated with a CILRT were not
identified.
Please provide the supplemental information within 30 days of the date of this
letter.
Sincerely.
O

Technical Specification 6.8.1 requires that written procedures be
established and implemented for surveillance and test activities of
safety-related equipment.
Procedure.1092.030, Revision 0, " Integrated Leak Rate Test," has
l
been established in accordance with this Technical Specification.
i
Appendix B of this procedure requires that the manually operated,
l
Instrument Cooling Water System Valve ICW-32 be placed in the open
'
position, and that valve positions be independently verified.
i
Contrary to the above, on November 2. 1988, the NRC inspector found
Valve ICW-32 to be in tha closed position.
The valve tag called for
'
the valve to be in the open position, as cpecified by Appendix B to
Procedure 1092.030.
Initials had been entered on the valve position
- ~
table in Appendix B to document that the "open". position for Valve
ICW-32 had been independently verified.
'
This is a Severity Level IV violation.
(Supplement I)
(50-313/88-35-01)
Response to Violation 50-313/88-35-01
(1)' The reason for the violation if admitted:
As discussed in an enforcement conference held at NRC Region IV
~ January 23, 1989, AP&L does admit the violation occurred as
stated above.
As a result of a valve misalignment which occurred during
performance of the ANO-2 CILRT in April 1988 (reference violation
368/8811-01), the AND-1 CILRT procedure had been revised, prior
to use in November 1988, to include independent verification of
valve' positions.
These procedural controls were adequate to
ensure valve ICW-2 was correctly positioned and verified in
accordance with the procedure during the initial CILRT alignment
on November 1, 1988.
However, AP&L believes that ICW-32 was
!
subsequently closed during attempts to stop water leakage in the
j
area, which was interfering with work activities in the reactor
'
building, due to a personnel error and inadequate knowledge of
the controls related to valve manipulations during performance
of the containment integrated leak rate test (CILRT).
(2) The corrective steps which have been taken and the results
achieved:
Immediate actions following identification of the mispositioned
valve, ICW-32, were to correctly align it in the CILRT
position (open) and to verify the position of other valves in the
reactor building prior to proceeding with the CILRT.
No
other mispositioned valves were identified.

(3) The corrective steps which will be taken to avoid further
violations:
L
As. discussed above, a valve misalignment had previously occurred
2
during the April 1988 performance of the ANO-2 CILRT.
Based on
this occurrence, the AND-1 CILRT procedure had been revised
prior to the performance of the test November 1988.
The CILRT
procedure.for ANO-2 is being revised to include an independent
.i
verification of valve position. This revision will be completed
"
prior to the next CILRT on ANO-2.
This action should ensure
that the initial CILRT alignment is performed correctly.
Additionally, to address the personnel error that is believed
'to have resulted in the mispositioning of ICW-32 following
,
initial CILRT alignments, training will be provided to appropriate
-'
personnel to include a discussion of the requirements associated
with CILRT tags and controls for performance of the test.
Also,
the CILRT tags will be revised to include warnings on both sides
to require Shift Supervisor's approval prior to changing the
position of a CILRT tagged valve or another warning / tagging
method' implemented as deemed appropriate.
(4) The date when full compliance will be achieved:
Full compliance was achieved November 3, 1988, following
realignment of ICW-32 and reverification of other valve positions.
.The future actions will be completed prior to the next CILRT
performed for the respective unit.
The test for ANO-1 should
occur in late 1991 or early 1992.
The ANO-2 test should occur
mid-1991.
