Dear Mr. Rueger:
SUBJECT:
INSPECTION OF THE PROCUREMENT AND COMMERCIAL GRADE
DEDICATION OF THE SIXTH (NO. 2-3)
EMERGENCY DIESEL
GENERATOR SET
FOR DIABLO CANYON NUCLEAR POWER PLANT
UNIT 2
(INSPECTION REPORT
NO. 50-323/92-201)
i
This letter transmits the report of the U.S. Nuclear Regulatory
Commission
(NRC) inspection conducted April 27 through
June
5,
1992, at the corporate offices of Pacific Gas and
Electric Company
(PG&E),
San Francisco,
The
NRC
inspection team,
led by Steven
M. Matthews and including the
other inspectors
named in the report, evaluated
PG&E's
procurement
and commercial grade dedication of an emergency
diesel generator
(EDG) set for Diablo Canyon Nuclear Power Plant
Unit 2
(DCNPP2).
We view PG&E's decision to install the sixth (No. 2-3)
EDG set as
an enhancement
to the safety of DCNPP.
The 2-3
EDG set will also
provide
DCNPP2 with significantly enhanced
operational
flexibilityto meet station blackout requirements
and minimize
limiting conditions for operation
and their effect.
Except for
the power generator
component,
PG&E procured the components
of
the sixth
EDG set as commercial grade equipment, similar to the
EDGs currently installed,
intending to dedicate
them for safety-
related service.
PG&E's procurement
and commercial grade dedication of the 2-3
assembly,
auxiliary systems,
and installation represent
a unique
and complex exercise in procurement
and dedication.
The team
recognized that the weaknesses
identified during its inspections,
were not indicative of PG&E's normal procurement
and standard
commercial grade dedication program or its implementation
(see
also
NRC Inspection Report
(IR) 50-275/91-201
and 50-323/91-201,
dated July 16, 1991).

Mr. G.
M. Rueger
J~
During its meeting in Rockville, Maryland,
on February
20,
1992,
with representatives
of the
NRC to discuss
the open issues
from
the previous inspections of PG&E, and PG&E's supplier of the
power generator
(NEI Peebles-Electric
Products,
Inc.
(P-EP), of
Cleveland,
Ohio,
and NEI Peebles
Limited, Peebles Electrical
Machines
(PEM), of Edinburgh,
Scotland),
PG&E presented
a revised
approach for its dedication of the diesel engine
and its
compensatory
actions taken for the power generator.
Also, during
this meeting,
PG&E agreed to develop, in consultation with GE
Locomotive of Montreal,
Canada
(manufacturer of the diesel engine
and designer of the 2-3
EDG set),
a program for supplemental
endurance testing (post-modification tests)
of the 2-3
EDG,
followed by a breakdown
and inspection of specific parts of the
engine
and power generator.
Although the exit meeting for this inspection
was conducted
on
June
5,
1992, the team continued to evaluate
PG&E documents
submitted after the meeting.
For instance,
the documentation
of
certain procedures
for the post-modification tests
and of PG&E's
evaluations of certain issues
were submitted in December
1992.
Therefore, this report documents
the 'team's review in the
following areas:
(1)
PG&E's commercial grade dedication of the
static exciter-voltage regulator including cabinets
and control
panels,
certain instrumentation
and control components,
piping,
and valves;
(2)
PG&E's compensatory
actions taken to resolve the
issues identified during the earlier inspection
(IR 50-323/91-202);
(3)
PG&E's compensatory
actions taken to
resolve the nonconformances
identified during the inspection of
P-EP
(IR 99900772/91-01);
(4)
PG&E's compensatory
actions taken
to resolve the unresolved
item and nonconformances
identified
during the inspection of PEM (IR 99901052/91-01);
(5)
PG&E's
revised dedication
approach for the diesel engine;
and
(6)
PG&E's
post-modification tests.
Closure of the issues identified during the inspections of PG&E,
P-EP,
and
PEM is pending
PG&E's successful
completion of its
compensatory
actions taken as
a result of the inspection findings
and the post-modification tests
and inspections that will
determine the adequacy of 2-3 EDG's design, materials,
and
manufacturing processes.
With the exception of certain
evaluations
addressed
below, these tests
and inspections
are
expected to resolve the team's remaining technical concerns
by
evaluating the
EDG during operating
and transient conditions
necessary
to detect problems,
and by subjecting certain
components
of the
EDG to operating cycles which would likely
result in premature cyclic fatigue failure if defects
were
present.
When the post-modification tests
are completed,
please
submit the
conclusions
from PG&E's evaluation of the completed test results.
PG&E will have successfully
concluded the dedication process
when
certain evaluations identified in the summary section of this
report as
open items,
have been completed
and incorporated into
the appropriate dedication documents.
PG&E is not requested
to
submit these
completed
documents to the
NRC staff.
However,

Mr .
G.
M. Rueger

these
documents
are subject to verification during future
NRC inspections.
