SUBJECT:
INTEGRATED DESIGN INSPECTION 50'-400/84-48
This letter conveys the results
and conclusions of the integrated
design
inspection of the Shearon Harris Nuclear
Power Plant, Unit 1 conducted
by the
NRC's Office of Inspection
and Enforcement.
The inspection
team was
composed
of personnel
from the NRC's Office of Inspection "and Enforcement,
Office of
Nuclear Reactor Regulation
and consultants.
The inspectioh took place at the
.Shearon Harris Nuclear Power Plant near Raleigh,
North Chrolina;
EBASCO
Services,
Incorporated,
New York City,'ew York; and Westinghouse
Electric
Corporation,
Pittsburgh,
over the period from December;3,
1984 to
February 13,
1985.
The inspection determined
whether
(1) regulatory'require-
ments
and design
bases
as specified in the license application
had been
correctly translated
and satisfied
as part of specifications,
drawings,
and"
procedures,
(2) correct design information had been provided internally and
externally to the responsible
design 'organizations,
(3) design engineers
had
sufficient technical
guidance to perform assigned
engineering functions,
and
(4) design controls,
as applied to the qriginal design,
had also
been applied
to design
changes,
including field changes.
I
The inspection-focused
on the chemical
and volume control system,
although other
areas
were also covered
as delineateti ih the enclosed
inspection report.
Activities included examination" of design,
design
bases,
design procedures,
'.
records,
and inspection of the systems
as installed at the plant.
Emphasis
was
placed
on- reviewing the adequacy of design details
as
a means of 'measuringhow
well the design process
had fun'ctioned for the selected
samples.
Deficiencies 'regarding errors,
procedural
vi,olations and inconsistencies
are
identi,ied-in the report.
Unresolved
items are identified where more information
is needed to reach conclusions.
Other observations
are identified where it was
considered
appropriate to call your attenti,on to IIIatters, which are not deficien-
'ies or unresolved
items, but which are
recommended for your consideration.

Chapter
1 of the report provides
a summary of the results of the inspection
and
the concl.usions
reached
by the inspection
team.
'There are several significant
- technical
areas
in the Shearon,Harris
design which indicate weaknesses
in the
design pro'cess'nd,
.therefore,
raise the possibility that similar weaknesses
will be found in systems
other than those
inspected
by the team.
These
are
identified below.
P
"t
(1)
Voltage drop considerations
were not properly accounted for in a number
of'nalyses.
(2),'.
The design of the containment
sump did not follow .the guidance
given in
Regulatory Guide 1.82 which you committed to follow.
r
(3)'elay coordination
was not effectively accomplished.
(4).
The design of slender struts
used to support piping systems
did not
address their dynamic excitat>on
and eccentricity.
(5)
Ra'diation protection analyses
performed
by EBASCO's Applied Physics
Department. had'umerous
non-conser vatisms
and errors.
(6)
Seismic II'/I (non-sei'smic piping, equipment,
and components
whose failure
could aff'ect seismic
Category~ I qquipment)'nalyses
were incomplete
and
deficient, with a walkdown planned to resolve problems.
" In addition to the conclusions
in Chapter
1 which relate to particular disciplines
'the te".m identified in Chapter 7of the report
some concerns
which were
common
to more than
one discipline.
These include:
(1)'t.e
EBASCO verification process
w'as not as effective as could be expected,
as indicated by the number and nature of the deficiencies
found by the
inspection..
The team concluded that this indicates
a lack of'anagement
attenti'on to an i'mportant area of the desig'n process.
(2)
Certain deficiencies
were, found. in the design performed on-site
by
Carolina
Power
and: Light which will likely require design
and hardware
changes.
(3)
Inappropriate
use of the "minor design
change" clqssification
has resulted
in situations
where the team concluded that appropsriate
independent
design
verification reviews
may have
been
ommitted.
a
It=i's: our understanding that responsibility for performance of certain original
desi'gn work's being shifted to your on'site engineering
organization to smooth
the transition from construction to opeFations,
such that Carolina
Power and Light
wil'l.have more design capability during the operational
phase.
Me: consider'this
intent to be commendabie
and are in complete
agreement
with
the ultimate objective.
However, it does
no
appear that
some parts of the
current. organization
possessed
the requisite experience
and training to
undertake
the expected responsibilities.

The report and its summaries
have highlighted only the problem areas
identified
, during the inspection.
To present
a properly balanced picture, it should
be
understood that the identified deficiencies
were based
on review of thousands
of page:. of technical
documentation
taking approximately
8 weeks
by an
, experienced
inspection
team.
When al'; of these factors are taken into consideration,
the
NRC staff concludes
that the overall
Shearon Harris plant design. process
has
been adequately
controlled, provided that effective corrective action is implemented to
satisfactorily resolve the items identified in this inspection report,
and the
root causes.
r
You are requested
to respond in writing to the deficiencies
and unresolved
items
'and to the
common concerns
addressed
in Chapter
7 of the report within 60 days
after receipt of this letter.
In your assessment
of individual deficiencies
and
common concerns identified in the inspection report, you are requested
to
address
the cause,
the extent to which the condition may be reflected in the
unreviewed portion of the design,
action to correct the existing condition,
action to prevent recurrence,
and any other information you consider relevant.
." For unresolved
items, the response
should provide information needed
to reach
conclusions
concerning acceptability of the specific fe'ature or practice
involved.
Comments
on observations
may be included in your response
in
addition to the requested
information.
In accordance
with 10 CFR 2. 790(a),
a copy of this letter and the enclosures
will be placed in the
NRC Public Document
Room unless
you notify this office by
telephone,
within 10 days of the date of this letter,
and submit written
application to 'withhold information contained herein within 25 days of the date
of"this letter.
Such applications
shall
be consistent with the requirements
of. 10
C>~R 2. 790(b)(1).
Should you have any questions
concerning this inspection,
please
