!
Units 1, 2,
and 3.
This inspection was documented in NRC
!
Inspection Report Nos. 50-206/93-01, 50-361/93-01, and 50-362/93-f 01.
,

l ENCLOSURE i
I
REPLY TO A NOTICE OF VIOLATION j
,
t The enclosure to Mr. Miller's letter dated February 25, 1993,
[
states in part:
"A.
10 CFR Part 50, Appendix B, Criterion XVI, ' Corrective l
Actions,' states: ' Measures shall be established to assure l
that conditions adverse to quality, such as...
deviations...
are promptly identified and corrected.'
" San Onofre Units 2 and 3 Updated Final Safety Analysis
Report (UFSAR), Section 9.5.4.1.
states: 'The diesel
!
generator fuel system is designed to ANSI standard N-195.'
,
t
" ANSI standard N-195, Appendix B,
' Alternate Calculation of
Fuel Oil Storage Capacity,' states:
'A minimum of 10% is.
t added to the calculated storage requirement if this
!
I alternative calculational appro'ach is used.'
i
" Contrary to the above, on June 18, 1991, the Licensee issued Calculation M-0016-008, supplement A,
'DG n-ite Fuel Oil Requirements' which did not include the 10 percent margin required for determining minimum fuel oil storage capacity even though this error was identified in Inspection Report 50-361, 50-362/89-200, dated January 12, 1990.
Calculation M-0016-008 superseded Calculation M16.4.
Both l
calculations used ANSI standard N195, Appendix B, methods.
'
The licensee did not correct the 10% margin omission until January 25, 1993.
"This is a severity Level IV violation (Supplement'I)."

i l
RESPONSE j
,
I
,
I.
REASON FOR THE VIOLATION l
!
'
Failure to Document Discrepancy (
i
,
Contrary to procedures and training, SCE individuals j
were aware of the error in the calculation but failed to l
'
initiate a corrective action document when the omission was l
-
identified.
A Nonconformance Report (NCR) or other-
!
corrective action document should have been generated to f
"
document the deficiency.
l r
II.
CORRECTIVE STEPS THAT HAVE BEEN TAKEN
-
I
,
l Calculation Revised l
I-l
i In January 1993, prior to the NRC inspection, SCE was j
'
preparing Interin Calculation Change Notices (ICCNs) for j
calculation M-0016-008 (which superseded M16.4) to j
incorporate additional loads on the diesel resulting from i
on-going design tasks.
During the process, SCE discovered l
the omission of the 10% margin in the calculation and
'l documented it on an NCR on January 12, 1993, in accordance
[
i with corrective action procedures.
Revision 2 to M-0016-008
!
"
was issued on January 25, 1993, to correct the 10% margin i
'
j omission.
The revision also incorporated the design changes-
!
in lieu of the ICCNs.
$
!
Previous Corrective Action and Procram Enhancements
,
Subsequent to 'the time personnel failed to document the
,
.
deficiency, Engineering instituted substantial program and j
i training improvements.
In 1990 as part of this improvement t
l effort, SCE instituted an enhanced training program titled i
i
" Technical Training for Nuclear Engineering and Design f
'
Organization - (NEDO) Personnel."
The training program j
includes training modules on " Problem Reporting Mechanisms,"
'
>
" Drawings, Codes and Standards," and "Nonconformance Reports
{
(NCRs)."
The training is required for all NEDO system l
j.
engineers and supervisors.
i
!
This enhanced training program educates engineers to f
"
promptly initiate appropriate corrective action documents t
when errors and other deficiencies are identified in design l
documents, including calculations.
l l
i
!
t III. CORRECTIVE STEPS THAT WILL BE TAKEN i
,
!
No further corrective actions are required.
