This will acknowledge receipt of your September 22,1997 letter in response to our August 22,
L1997 letter transmitting a Notice of Violation associated with the above mentioned inspection
report. We have reviewed your corrective actions and have no further questionr, at this time.
These conective actions may be examined auring future inspections.
We find the actions to the violations described in your response to be acceptable. However, the
. dates, listed in your response, under "Date when full compliance will be met" for violat'on -
- 50-254/265/97010-03a(DRS) and 50-254/265/97010-03b(DRS), are June 17,1997 and April
15,1997 respectively. Since the violation involved a lack of appropriate corrective action to -
prevent recurrence, full compliance can not be achieved until the corrective action changes and
- training have been completed on March 31,1998. During a telephone conversation on
'
October 8,1997, your personnel agreed that March 31,1998, was the appropriate date. No
additional response will be necessary.

STATEMENT OF VIOLATION (NRC IR 97-010);
t
.
1.
10 CFR 50, Appendix B, Criterion III, " Design Control," requires that measures be
established for the selection and review for suitability of application of pans,
equipment and processes that are essential to the safety related functions of thec
- structures, systems and components.
Contrary to the above, adequate design control mersures were not used for the
following design changes:
a.-
Alternate parts evaluation Q-1997-0023-00, issued April 15, 1997, authorized
the replacement of inodel 150BMPDR89 (model 89) air stan motors on the
Unit 2 (U 2) emergency diesel generator (EDG) with model 150BMPDR88
(model 88) motors as a like-for-like replacement. However, the new model 88
air start motors contained significant dimensional differences from the model
89 motors, thus resulting in a design change. As a result, the U-2 EDG failed
- y
to start during maintenance verification testir:g on May 8,1997
I
(254/265/97010-Ola(DRS)).
b.
Alternate pans evaluation M930030008, issued May 23,1994, authorized the
replacement of residual heat removal beat exchanger relief valve 2-1001-165A,
n
Type 1910MC-1-XMC324 (vapor trim), with a Type 1910MC-IXLS324 (liquid
trirn) valve. . The replacement valve type contained documental functional
_
differences, including re-closing pressure, from the original valve @, thus
resulting in a design change. As a result, two replacement uives of the vapor
trim type failed to re-close during testing (254/265/97010-Olb(DRS)).
,
'Ihis is a Severity Level IV violation (Supplement 1).
REASON FOR VIOLATION:
254/265/97010-Ola
Comed accepts the violt. tion. Alternate parts evaluation Q-1997-0023-00, issued
April 15,1997, was perfonned to evaluate the differences discovered between the original
model 150BMPDR89 air stan motors (ASMs) and the model 150BMPDR88 ASM.' Station
_ personnel did not recognize this as a design chang and failed to correctly implement the
.
design control program; In addition, the procedures did not clearly differentiate between
_
,
alternate parts and replacement parts and design changes.

,
'
ACTIONS TAKFE:
1.-
The original relief valve S/N TH78257 was repaired. - The valve was reinstalled and
tested satisfactorily using the Quarterly RHR Service Water Pump Operability Test,
'

(
May 23,1994) were reviewed and marked VOID.
,
4.
This event was presented to engineering personnel and a set of design change criteria
was dik:ussed. An interim review group of senior engineering personnel was
established to verify that the criterion are understood and design changes are not
i:
being performed by Engineering Requests.
,
ACTIONS TO PREVENT FURTHER OCCURRENCE:
l
- 1.
Procedure NEP 11-01, " Procurement and Use of Items for Repair and Replacement of
Safety Related and Regulatory Related Equipment" will be revised to include the need

Criterion XI of 10 CFR 50, Appendix B, " Test Control," requires that testing be
' performed to demonstrate that structures, systems and components will perform
satisfactory in service and that the testing be performed in accordance with r/ritten
test procedures which incorporate requirements and acceptance limits. Test results
shall be documented and evaluated to assure that test requirements have been
satisfied.
Contiary to the above:
On May 16,1997, after installation of model 150BMPDR88 air start motors with
mounting shims on EDGs U-2 and U-1/2, the licensee failed to perfomi adequate
testing to ensum that the EDGs would start as required (254/265/97010-02 (DRS)).
This is a Severity Level IV violation (Supplement 1).
REASON FOR VIOLATION:
O
254/263/97010-02
4
Comed accepts the violation. W new model 150BMPDR88 air start motors were installed
on the Unit 2 atxi the Shared Emergency Diesel Generators. Station pe sonnel used the
alternate parts replacement versus the design change pmcess. Station personnel did not
recognize that installation of Qc new model 150BMPDR88 air start motors was a design
change and required post modification testing in addition to the normal surveillance testing.
ACTIDNS TAKEN:
1.
The model 88 ASMs were removed and vendor supplied rebuilt model 89 ASMs were
installed on June 17,1997 on the Shared EDG and on June 18,1997 for Unit Two
EDO.- Following installation of the model 89 ASM the Monthly Emergency Diesel

3.
'10 CFR 50, App:ndix B, Criterion XVI, " Corrective Ahtions," requires that _
conditions adverse to quality be promptly identified and corrected and that for
signd", cant conditions adverse to quality the cause of the condition be determined and
correcti e action be taken to preclude repetition.
Contrary to the above:
'
a.
Because of the ' continuing reliance on an inadequate alt:rnate pants evaluation
and inadcquate testing, sufficient action was not promptly completed to _
,
- identify and conect the cause of the May 8,1997 failure to sta.t of the U 2
EDG following installation of the model 88 air start motors. As a result,
,
model 88 air start motors were installed on the U-1/2 EDG on May 17,1997.
T14 model 88 air statt motors were subsequently determined to be
,
unacceptable and the U 2 and U-1/2 EDGs were declared inoperable on
June 12,1997 (254/265/97010-03a(DRS)).
p
b.
Inadequate alternate parts evaluations, a condition adverse to quality, was not
identified as a cause of the failures during testing of two liqui? trim type
- replacement relief valves following the April 5,1997 failure or~ the residual-
- heat removal heat exchanger relief valve. As a result, actions to correct
inadequate alternate parts evaluations had not been taken as of the stant of the
inspection on June 9,19971254/265/97010-03b(DRS)).
'Ihis is a Severity I.evel IV violation (Supplement 1).
.
REASON FOR VIOLATION:
254/265/97010-03a
Condid accepts the violation. Timely conective action was not taken in this instance because
the Station did not recognize the new model ASM as a design change and did not evaluate
their acceptability.
REASON FOR VIOLATION:
254/265/9701H3b
ComBd accepts the violation. The root cause evaluation performed in April,1997, did not
identify why the design change process was not being implemented properly.
.
'
(~N
In _both cases the Station did not recognize that the alternate parts evaluations process was not
the conect design control process and that the design change process should have been used.
