Ins ection durin
the
eriod of A ril 15-26
1985
(Re ort No. 50-397/85-11)
Areas Ins ected:
A special,
unannounced
team inspection of maintenance,
measuring
and test equipment
(MME), surveillance testing, quality assurance
activities, onsite/offsite
committee activities,
employee training, health
physics waste programs, plant procedures,
design
changes
and modifications,
and vendor field and technical
manual
change notices.
The team's
approach
was to direct 60 percent of its effort on administrative
controls associated
with the emergency
DGs, the .HPSI" and 'RHR systems
and the
implementation
and adherence
of those controls in the following areas:
MME
Calibration Program;
Maintenance
Program; Surveillance
Program;
Vendor Field
Change Notices;
and Design Changes
and Modifications.
The other 40 percent of
the team's effort was on administrative controls'i'n,the following important
areas:
onsite/offsite
committee activities; quality, assurance
audits (onsite
and offsite); licensed/non-licensed
operator train'ing
plant-operations;
health physics solid waste program; health physics liquids and liquids waste
program;
and health physics
gaseous
waste
system'.

u
The team's strategy
used for thi's'nspection
required the selection of a
sample of MNP-2 administrative'ontrols
associated
with four important
safety-related
systems
(HPSI,
and Station 3atte'ries)
of
. the plant for vigorous examination.
The sample
was representative
of all
management
controls, testing,
methodology
and documentation of all
safey-related
administrative controls a't the WNP-2 Nuclear Power Plant.

have
been established
and are functioning in conformance with'echnical
Specification requirements
and commitments in the application.
a.
Nuclear Safet

(NSAG)i
The NSAG is responsible for performing indepen'dent'eview
of plant
activities including maintenance,
modifications, operational
problems,
operational analysis
and to aid in the establishment
of
programmatic requirements, for plant activities.
For this inspection
the following documents
were reviewed:
Administrative Procedures

The NSAG is composed of five degree'd, full ctime,'edicated
engineers
located at the VNP-2 site.
Internal 'reports>,(NCRs,
and
LERs
etc.)
and external reports
(NRC,
INPO,
GE etc.) are reviewed"by
NSAG
or screened
by the
NSAG Manager.
These reports"are
assigned
an
identification number
and tracked by the computerized
Action~
Tracking System.
Corrective actions, if required,'re
entered into
the Plant Tracking Log (PTL).
'Plant significant events
are being
investigated
and reported
on by the
NSAG.
A review of two of these
reports,
"NSAG Assessments
of Training Practices
on'hanges
and
Logkeeping" revealed that the reports
are very well written.
The
investigations
appear to-be comprehensive,
with a well defined
problem,
a complete description of the event causing the problem and
detailed
recommendations
for corrective actions.
The inspectors
found no full policy statement at the corporate level
on NSAG and no engineers
at the corporate
home office serving on
NSAG.
b.
Plant 0 erations
Committee
(POC)
The
POC is the onsite review-group required by Technical Specification (TS) 6.5.1.
POC guidance
and responsibilities
are
contained in Administrative Procedure
1.1.5,
and the TS.
The plant
administrative
manager is the permanent
secretary to the
POC and
maintains all of POC records.
The minutes of all meeting"held since
January
1,
1985
(12 meetings),
were examined by the inspectors.
The
committee is very active and appears
to be meeting all of its
responsibilities.
C.
Cor orate Nuclear Safet

meetings
and any deemed significant by any member will be
discussed utilizing a technical presentation.
The
Executive Secretary will document his review as being
under the criteria of 10 CFR 50.59."
As the instructions reveal,
the full committee is not reviewing all
of the required
documents but is making sure that an independent
review is being made.
With this exception the inspectors
determined
that the
CNSRB is meeting all of its required responsibilities.
Two violations were identified in this area
(85-11-01/02).

Containment Inte rit Verification (397/85-12-02)
Closed
The radiation levels in the reactor water cleanup
(RWCU) vault was
determined to be from 60 to 200 mr so that the area
above the vault
should not be considered
At least the radiation
levels should not be considered
too high, for an operator to go into for 5
or 10 minutes to verify that the valves were closed without prior
approval by the Plant Operations
Committee
and the Plant Manager.
Proposed
TS changes
were submitted
on April 25,
1985, to except the
subject valves from the general surveillance
requirement.
This item is

In addition to the above procedures,
the inspector also reviewed
individual procedures pertaining to the calibration of crimpers,
Class
1, pressure
colorimeters,
hydrometers,
and others.
The
inspector also discussed
the program with supervisors
responsible
for the various requirements
of the procedures.
Calibration is accomplished
through three methods at the
MNP-2 site.
M&TE is sent offsite to a Standards
Laboratory which is
located'n
the Plant Support Center.
Most of the
M&TE is calibrated at
the lab itself but some items are sent to evaluated
suppliers
to be calibrated.
In either case
the
M&TE is checked and/or
calibrated before return to the plant by the Standards
Laboratory.
Operation of the Standards
Laboratory is governed
by Standards
Lab Instructions
(SLI).
H&TE such
as torque wrenches,
calipers,
micrometers,
and dial
indicators are calibrated onsite by plant personnel.
The

calibration is controlled by PPM 1.5.4, "Control of MSTE", and
performed in accordance
with the appendices
to that procedure.
M&TE such
as hydrometers,
crimpers,
pressure
and others
are calibrated by Chemistry Lab and Instrumentation
and Control
(ISC) personnel in accordance
with procedures
in the Plant
Procedures
Manual.
These calibrations
and their frequencies
are controlled by PPM 10.1.5,
"Scheduled
Maintenance
System."
The inspector
concluded that the licensee's
gA program for MME has
provisions that include:
assignment
of responsibilities
to assure calibration and
control of MME,
criteria and responsibility for assignment
of calibration
frequency,
requirements
for labeling MME with the latest calibration
status
and due date,
an equipment inventory matrix which includes all MME used
on
safety-related
systems,
a system to assure
that new MME are
added to the inventory
matrix and calibrated prior to being placed in service,
a system to assure
that MME are recalled
and calibrated before
the calibration period has expired,
controls to preclude inadvertent
use of MME for which the
calibration period has expired,
controls assuring
the acceptability of items previously tested
or measured
using out-of-calibration MME and evaluation of the
cause of out-of-calibration status,
and
requirements
that calibrations
be performed in accordance
with
procedures,
manufacturer's
specifications',
or written
instructions.

(Deficiency Reports)
The inspector
reviewed plant gA surveillance reports
and corporate
gA audits to determine
the types of problems that the licensee
had
experienced
and what the corrective actions
were.
The inspector
also discussed
the findings of these reports with cognizant
gA
personnel.
The inspector performed visual inspections
of HGTE in use throughout
the plant to assure
that calibrated
equipment
was being used.
These
inspections
included
HSTE:
stoxed in the tool crib
used in the Standards
Laboratory
used in the Health Physics
and Chemistry Laboratory
used in the various Maintenance
Shops,
and
in use in various other areas
of the plant
No cases of non-calibrated
equipment being used were identified.
Control of MME is defined by Administrative Procedure
1.5.4,
"Control of Heasuring
and Test Equipment -,Transfer Standards."
This procedures
sets forth the requirements'nd
responsibilities for
control of the usage,
storage,
records,
and,calibration of MME.
A tool crib has
been establishedfor the'torage'f all HSrTE.
This
tool crib is controlled by, a storekeeper'wh6
distributes
and
collects
HSTE as it is needed
by plant personnel.
A Test equipment
Log and
a calibration record is maintaineg'n the,tool'icxib files
for each piece of MGTE to establish
equipment status'.
" Tiie Test
Equipment Log must be filled out each time,a piece of HGTE.is
checked out of the tool crib.
HRTE must, subsequently
be checked in
on the Test Equipment Log upon return to t!he tool crib;= 'Daily Usage
Records
are used to keep
an account of the work performed with a
piece of MME.
A Daily Usage Record is, filled out each" time
a piece
of MME is used to perform
a procedure,
test,
or work request.
These
records
are collected
and reviewed by Plant Engineering for
use of out-of-calibration MME and t'o perform analyses
on data in
the event
an out-of-calibration condition is identified.
From the review of records, visual inspections,
and personnel
discussions,
the inspectox
found the following in relation to the
control of ATE that are contrary to the requirements
outlined in
PPH 1.5,4.
While inspecting
contaminated
MME stored
on the 525 level of
the Radwaste Building, the inspector noticed the following
overdue-for-calibration test
guages
being stored together with
calibrated
equipment:

AP 1.5.4 Section 6.E.2 states,
"A quarantine
locker shall be
used for all test equipment
removed
from service or awaiting
calibration."
A quarantine
locker has been established
in the
tool crib and is being used in accordance
with this
requirement.
However, the Radwaste Building storage
area
has
no quarantine
locker and equipment storage is commingled. It
is possible that overdue-for-calibration, equipment
could be
used to perform tests.
While reviewing the overdue-for-calibration report, which is
compiled
and distributed by the Standards
Laboratory,
and
associated
MME records,
the inspector noted that the following
equipment,
which were not checked
out on the Test Equipment
Logs, were missing from the tool crib.

None of the items listed above could be located in the plant.
Plant personnel believe the Visicorder plug-ins to have been
shipped
back to the vendor with the visicorder frame.
They
also believe the
PTC Thermometers
to be stolen.
AP 1.5.4
Section G.E.1 states,
"When not checked out,
MME shall be
maintained
under controlled storage conditions."
The fact that
equipment is missing
and cannot
be found raises
doubt as to the
adequacy of the control of the storage
area (tool crib).
During the course of the inspection,
the inspector
noted
specific instances
of deficient lKTE control in the use of IRD
820 Vibration Monitors.
Monitor No.

was signed in on the
Test Equipment Log in the tool crib on March 13,
1985,
and has

on April 14,
1985, without documentation
to
prove its calibration date.
Whereupon, it was pressed
into
service again without a Test Equipment 'Log or Daily Usage
Records being maintained.",.These
actions
were taken, by
personnel
other than the tool crib'storekeeper
who has the
responsibility for shipments
to the tool crib for calibration.
Monitor No. 40928 is'ontinuously signed out to the control
room.
During the last period of check-out,
the monitor was
sent to the Standards
L'ab for'calibration.
On April 19,
1985,
the monitor was returned
from, the Standards
Lab to .the,
mechanical
shop where it was'put into use.
One Foreman stated
to the inspector that no,documeritation
was returne'd with the
instrument
and that the mechanical
shop
does not maintain
a
Test Equipment Log or Daily,'Usage, Records.
This'onitor is
signed out, stored in the control ..room,. and used by the
operating
crew for surveillance testing.
sf
AP 1.5.4 Section 6.E.3 states,
"A Test Equipment Log shall be
provided at the
M&TE tool cribs for use in. checking out or in
M&TE."
Section 6.F.l states,
"A M&TE Daily Usage Record shall
be provided at the
M&TE tool cribs with each piece of M&TE as
it is checked out for personnel
to complete during usage
each
day.
When an individual will no longer need the
M&TE (NOT TO
EXCEED FIVE CALENDAR DAYS) or at the end of each day, the
completed
record is returned with the
M&TE to its storage
site."
Without a Test Equipment
Log and Daily Usage Records,
there is no record of where the instruments
were used.
The problems with Test Equipment I,ogs and Daily Usage Records
were not limited to the previously mentioned
cases.
In at
least
31 other cases
there were no Test Equipment Log entries
for instances
when Daily Usage Records
were completed (i.e.,
equipment
was used without being checked out).
In twelve other
cases
there were no Daily Usage
Records
on file for equipment
that was checked out on Test Equipment Logs (i.e., equipment
was checked
out and possibly'sed
without a record of the use).
Problems with the control of M&TE and .records
were identified
in four Plant
(}A Surveillance Reports
over the past nine
months.
Surveillance Report No. 2-85-018 identified 27 ca'ses
where Daily Usage Records
were inadequately
completed.
Surveillance Report No. 2-84-269 identified an instance
where
a
piece of M&TE was used by various personnel
during issuance
to
only one of those personnel (i.e., incomplete Test Equipment
I,og).
Surveillance Report No. 2-84-227 identified twelve
instances
where
M&TE was used without either
a Test Equipment,
Log Entry or Daily Usage Records.
Surveillance Report No.
2-84-187 identified thirteen instances
where Test Equipment
Logs and Daily Usage Records
were not completed properly.
The
corrective action taken in all four cases
was to give training
sessions
to personnel.
In one instance
(No. 2-84-227),
was revised for clarification (Rev. 5).

From the review of the above mentioned onsite
(}A surveillance
reports, it is clear that management
had previous
knowledge of
the MME programmatic
breakdown.
But, due to the lack of
proper management
oversite of the surveillances
and the
corrective actions performed because
of their findings, the
breakdown
was not recognized.
5.
Surveillances
The inspector
concluded that MME is not being controlled in
accordance
with the approved procedure
(PPM 1.54).
Even though
no instances
were found of equipment being used while
out-of-calibration, the lack of control could eventually lead
to this occurrence.
The Test Equipment Logs and Daily Usage
Records
are the basis for implementing storage
and usage
controls for MME.
Likewise, they provide the basis for the
Plant Engineering Reviews for out-of-calibration conditions.
Continuing inconsistencies
and inaccurate
records
could lead to
incorrect analyses
and result in equipment being used while
out-of-calibration.

The inspector noted that the records
were in
transition between construction
and operations for central storage.
Startup/Lineup test results
and pre-operational test results
were
produced for all eight, Class
1 station batteries.
The pre-operational
test included a,battery capacity test
and load profile test except in the
case of 24V batteries.

on reports of equipment malfunctions at other nuclear facilities.
Such
reports
included
NRC Bulletins and Information Notices,
INPO event
reports,
and manufacturer notifications of hardware deficiencies.
The
inspector
examined the review and action records associated
with 10
Information Notices,
5 Bulletins,
and 22 unresolved
actions associated
with event reports for the residual heat removal, high pressure
core
spray,
and diesel generator
systems, for the 1975 through

The inspector also
examined three vendor certified information manual
files at the plant, which are used by maintenance
personnel for repair
activities, to ascertain
incorporation of information relative to
hardware
changes
resulting from the event report corrective actions.
The Supply System reviews are conducted
by the onsite Nuclear Safety

Group
(NSAG), staffed by five engineers
in accordance
with

and records
show that these
have been
defined in general

'Furthermore,
although Plant
Procedure

as applf.cable to
test procedures.
This'mission
was reflected in some'WRs,
which
included only abbreviated test requirements,
where testing
was
required in addition to" that, specified by more thorough permanent
plant operability ver'ification procedures.
No significant

however,
the

appears
to be
a weakness in the

The Administrative Manager, committed to Supply System evaluation of
the test procedure preparation'instructions
with respect
to the
quality assurance
program requirements
(85-11-06).
I
Prioritization of (}ualit Control Ins ection Activities
Neither the design engineers
(in preparation of the DCPs) nor the
system engineers
(in preparation of the
MWRs) specify quality
control inspection hold points or other inspection requirements.
The quality control organization
reviews
MWRs and establishes
hold
points based
upon their own review.
The
MWR records
showed that the
inspection staff tended to invoke inspections
and hold points where
prestablished
inspection checklists already existed,
and tended to
not become involved in other activities,
some of which appeared
to
have high safety significance.
The inspector cited
MWRs AW-0926 and
0934
as
examples of work on safety-related
diesel generator
bearings
and
speed control logic, where inspection/verification activities
might be warranted.
Also noted
was planned additional work on
voltage adjustment potentionmeters,
where inadequacies
in control of
prior maintenance
work had resulted in NRC enforcement actions.
The plant equality Assurance
Manager noted that quality assurance
department staff were being given additional systems

Co
orate Review of Plant Modification Pro osals
The corporate policy procedure
(NOS-23) establishes
that any
employee
may initiate a proposed
design
change,
and that rejection
of any such proposal shall be documented with return to the
originator. It also requires that the Director of Power Generation
shall periodically review the file of rejected
PHRs.
There
was
no
documented
evidence of such
a review having been performed since the
issuance
of the procedure in March 1984, nor any files staff
recollection of such
a review.
The Director of Power Generation
stated that he had conducted
such reviews shortly after the
procedure
had been issued,
but not recently.
(The number of such
PHRs appears
to be only about
10 per year).
This appeared
to be one
example of a missed opportunity for corporate
management
to probe
into details of the plant administration.
With the consolidation of the Director of Power Generation functions
into the position of Assistant
Managing Director for Operations,
the
Deputy Managing Director stated that the policy NOS-23 would be
re-examined
to assess
whether this specific requirement
would be
retained in its present
form (85-11-08).
No violations or deviations
were identified.

f
Procedure
7.4.6.5.3.2,
which provides
foi."TS require'd flow testing
contains different acceptance, criter'ia than
TS "4.6.5.3(b)(3).
The
licensee
took immediate corrective action, by issuing
a procedure
change.
The inspector verified'hat the test
had not b'een performed
using the wrong criteria and that the system lineup test performed
during plant preoperational
testing pet the
TS required flow rate.
The source
check procedure
7.1.2"does
not contain acceptance
criteria.
The inspector noted that in one case,
the source
response
could be lower than the normal instrument
response.
The licensee
was aware of this situation and has initiated corrective action.
The TS definition of source
check does not imply quantitative
acceptance
criteria are required.
The inspector
observed portions of the daily instrument
checks
and
calibration of the liquid effluent monitor.
The inspector
observed
some technicians
were not fully knowledgeable of all radiation

Procedure
12.13.11,
"Radwaste Effluent Monitor" provides instruction
for a primary calibration as well as secondary
source calibration.
Calibration for other liquid monitors is provided in similar
procedures.
These procedures
considered with the instrument procedures
for
electronic calibration are considered
adequate
to implement the TS
calibration requirement.
No violations or deviations
were identified.
Offsite Dose Calculation Manual (ODCH)'m lementation
Technical Specification 6.8.l.i requires
a written program be
established,
implemented
and maintained for ODCH implementation.
Plant procedure

For this change,
no accompanying
analyses-or
evaluations
were included in the submittal documenting
the
appropriateness
of using the value for, Y-90.
In addition, the
'submittals did not contain the required determina'tion,that
the
changes will, not reduce the accuracy or reliability.
The inspector
identified these matters to a licensee
representative
in a telephone
conversation
subsequent
to the. inspectio'n.
The importance of strict
adherence
to TS requirements
was discussed
at the exit'nterview.
Semi-Annual Effluent Re ort
J
Technical Specification 6.9.1.11
contains
a requirement to submit
the semi-annual
radioactive effluent release
report'60
days
'ollowing
January
1 and July
1 of each year.
Addi'.onal reporting
requirements
are also contained within that specification.
The
inspector
reviewed reports
submitted for 1984 to determine if the
reporting requirements
of TS and referenced
Regulatory
Guide 1.21,
"Measuring, Evaluating,
and Reporting Radioactivity
in...Effluents...," Revision
1 were satisfied.
The review identified one typographic error which was identified to
the licensee.
The inspector noted that calculations
are based in
large part on minimum detectable activity reporting levels.
For
example 'for 1984, only Cobalt-58,
Zinc-65, Tritium, Sodium-24,
Copper-64,
and Arsenic-76 exceeded
the
MDA for liquids.
Reported releases
based
on MDA values
accounted for at least half
the liquid activity released.
Gaseous
effluent releases
reported
for 1984 were very low, the maximum value being only 0.17 percent of
a TS limit.
The inspector
examined selected
records
used in production of the
semi-annual
reports.

Notwithstanding the exceptions
noted in Section

data used for preparation of the semi-annual effluent report
calculations
was found consistent with plant effluent release
data.
Techniques
used to prepare
the semi-annual
report were discussed
with responsible
individuals and found generally acceptable.
This
inspection only considered
selective
review of input data for dose
projections
and reports
and did not attempt to validate
dose
calculation methodology.
Validations performed by the licensee
are
discussed
elsewhere in this report.
No violations or deviations
were identified.
S stem Chemistr
The inspector
examined selected
reactor coolant system surveillances
performed to meet
TS requirements.
The review was conducted
by
verifying that hydrogen ion concentration
(ph), chloride,
conductivity and iodine dose equivalent analysis
were performed at
the required frequency from January
1,
1985 to date,
and that
parameters
were within the
TS limits.
Performance
of surveillance
procedure 7.4.11.2.1.2.3
which implements
TS requirements
to take
samples
following startups,
shutdowns
and thermal power changes
exceeding
15 percent in one hour was examined.
The inspector
verified that samples
were taken
as required for the period
January
1,
1984 to date.
The inspector noted that this procedure
did not identify the fact that samples
are required at least
once
per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for at least

The inspector pointed out to a licens'ee 'representative
that the
procedure
did not fully implement the surveillance'equirement
in
that no provision was
made to take more than one sample 'or to check
the effluent monitor or iodine concentration.,

required are entered in the lice'nsee's
master schedule.
L'alibration
procedures
were examined
and found acceptable
as
described in Section
1 of;this paragraph.
No violations or deviations were'identified.
Technical Specification 3.11.2.1- sets
fort'.h the requi'rement to
control the instantaneous
gaseous
effluent dose'ate.
Calculation
of alarm setpoints
to implement'his'emi'rement's
described. in the
licensee's offsite dose calculation manual
(ODCM) section 3.6.1,
"Calculation of Gaseous Effluent Monitor Alarm Se'tpoints".
This
procedure
describes
three requirements
for the calculation:
monthly isotopic analysis of effluent releases
are performed;
partitioning of releases
to the three
gaseous
effluent release
points are considered;
both skin and whole body dose alarm setpoints will be
calculated with the most limiting selected.
The inspector
examined
the licensee's
calculations
to verify proper
implementation of this requirement.
The inspector also
examined the
licensee's
methods for controlling instrument setpoints.
The
inspector
examined similar items for the liquid release point.

Implementation of TS 6.8.1
was examined by review 'of the required
procedures.
PPH 1.11.5,
"equality Assurance

requirement.
Implementation of PPM 1.11;5,
step 1.11.5.3.6.d
regarding quality
control of effluent monitors states."
Independent verification of a
substantial fraction of computations
are performed by a second
individual."
Computations
required for effluent monitoring are not defined by
procedure
1.11.5.
Technical Specification 3/4.11.1
and 3/4.11.2
contain requirements
to control, calculate'and
report releases
based
upon effluent monitor readings
and sample results.
These
calculations
were examined
by the inspector.
The inspector also
examined procedures
established
to implement these calculations
as
described in section
b of this paragraph.
Calculations to implement
TS 3/4.11.1
and 3/4.11.2 are performed by
the station radiochemist using the 7.4.11 series of surveillance
procedures
and various
computer programs
developed at the station
which are run on small computers.
These calculations
are also
performed by Radiological Programs,
which is part of the support
services
organization,
at the plant support facility (PSF).
Radiological Programs
uses
NRC approved
codes
GASPAR and IADTAP to
calculate
doses to the offsite population.
The station performs
simpler calculations
using the methodology of the offsite dose
calculation manual
(ODCM).
The two techniques
produce differing
estimates
of the
same values using the
same liquid effluent data
and
slightly different initial data for noble
gas releases.
The
differences
are not significant provided the systems
used operate
properly but make it difficult to directly compare
the results.
Plant procedures
directing calculations permit the use of computer
programs
as
a substitute for hand calculations.
Review of the
procedures
involved revealed
no quality control instructions
when
computer programs
are used.
In addition,
PPM 1.11.5 provides
no
additional guidance in this regard.
Section C.6.4 provides
guidance
on quality control when computers
are utilized.
Section 6.4 states
in part, "For computer calculations,
the input
data
should be verified by a knowledgeable individual.
All computer
programs
should be documented
and verified before initial routine
use.
The inspector attempted
to determine if step 1.11.5.3.6.d of
PPM 1.11.5
was being implemented with respect
to TS 3.11.1
and
3.11.2 calculations.

The following findings were identified which outline deficiencies in
this area.
t
Documentation of the liquid release
calculations
and two gaseous
release
calculation programs
use'd during 1984 and
1985 to",da'te,were
examined.
Documentation of marginal quality was'available
for
liquid release
calculations.
Documentation for the gaseous
release
calculation programs
was not available.
The secondgaseous

computer program which was recently implemented,did'ave
documentation in preparation.
E
During the inspection,
the inspector'was 'not presented, satisfactory
evidence that independent verification of a subst'antial-fraction
of
computations
were performed by a second
$iidividual,, Independent
verification of overall computational results
was performed by a
comparison of the results
obtained by Radiological Programs
independent
of those performed by the plant staff.
Licensee
representatives
maintained that these
comparisons
served to meet the
intent of PPM 1.11.5.
These
comparisons
were performed but not
formally documented.
These
comparisons
did serve
a useful purpose
in that several errors in computer programs
were identified and
corrected.
The identification and correction of errors
was not documented
using
plant reporting systems
such
as problem reports,
nonconformance
reports or other means.
One error in computer calculations pointed out to the inspector
resulted in substantial
underestimate
of a dose parameter
required
to be calculated
by the TS.
This error, while known to the
responsible individual, remained unreported for three months.
These
errors
were identified in computer programs in use for performing
TS
required calculations.
Performance
of calculations to verify computer programs
were
performed to some extent.
The inspector
was not offered evidence
that verification of computer programs
was performed by a second
individual.
Documented tests,
containing test computer runs,
comparing expected
output to actual
computer output. were not
available.
These tests
were undergoing completion during the
inspection period for the second
gaseous
effluent release
computer
program.
This program
was implemented for use prior to completion
of the test effort.
The inspector did not attempt to validate the licensee's
dose
calculations that were performed at the site or by Radiological
Programs at the plant support facility.
The inspector did review portions of calculations
performed by both
parties.
Review of monthly data
and calculations
performed at the
plant revealed
a problem with computer calculations for the liquid
effluent doses.
The responsible
licensee
representative
reviewed
the problem and took corrective action.

Projected
doses for liquid effluent releases
calculated
by plant
staff and by radiological programs
were compared for the fourth
quarter of 1984.
These
were found in good agreement
on
a monthly
and quarterly basis.
The inspector
compared calculations of release
rates
and curies
released
performed by the plant with those performed by radiological
programs using the Radiological Effluent Management
(REM) program.
The inspector identified a problem with these calculations.
Investigation by the licensee
revealed
an error in one equation used
in the computer
code used by Radiologica1 Programs.
The licensee
representative
assured
the inspector that this, code had not yet been
validated
and that this code
was not used ta perform any of the
semi-annual
release
report calculations.
The inspector noted that written verification packages
were
available for codes
used by'adiological programs.
Regarding
regulatory guide 4.15 section C.6.4 computer data input
verification, the licensee
representative
at the plant stated that
computer input data is checked after input,'with the'origi'nal data
sheets.
The inspector noted that this) was not,a procedural
requirement
and that
no, place, was provided,for any..individual to
sign-off that such
a check had been. completed'.,
The. inspector
could
not verify that these'hecks'ad

programs to,perform'S required
calculations.
Failure to adequately'ocument
the codes, their
validation and the v'erificati'on, of 'input data re'present
poor
implementation of quality control requirements
in"this, a'rea.
Ongoing informal activities have served to identify'some problems in
this area but these
problems
have not been appropriately
documented.
Based
on findings identified during the inspection,
the licensee
was
prepared at the exit interview -to offer a substantial
commitment
towards program verification.
The commitment offered by the
licensee
described
steps
to be taken tovdocument
and verify computer
codes prior to use.
These
steps
describe
an acceptable
method of
verification.
The following will be examined in a subsequent
inspection:
documentation
and verification of programs in use;
procedural
changes
to implement this commitment;
provisions for verification of computer input data;
Based
on the licensee's
commitment t'o improve in this area,
a notice
of deviation from Regulatory Guide
4'5 was considered
not
appropriate.

The inspector
examined implementation of the licensee's
laboratory
analytical control (IAC) program.
Plant procedure
11.2.7 contains

each technician is required to perform every six months.
These
parameters
are chloride, silica, organic phosphate
and boron.
The
inspector discussed
with licensee
representatives
the need to
consider including more parameters
in this program.
Acceptance criteria for the spike sample
are calculated
using the
statistical t-test.
Use of this test leads to acceptance
criteria
of sample
mean plus or minus
12 standard deviations'he
inspector
noted that while statistically valid, this technique
did not appear
appropriate for plant use
and suggested
that the acceptance
criteria
be redefined.
The licensee representative
agreed to consider this
matter.
The inspector noted that no program had been established
to trend
spike sample results.
No requirement exists in this area.
The inspector
examined the routine use of standards
called for by
the LAC.
This area
was found acceptable.
The inspector noted that no chemistry procedure is available to
describe responsibilities for review of work.
A plant procedure is
available.
In addition,
some chemistry procedures
did not contain
provision for supervisory acceptance
while others did.
This matter
was identified to licensee
representatives.
The inspector
examined
the licensee's
cross
check program which
consists of blind samples
supplied by a commercial laboratory,
the
EPA and
NRG.
Review of this data revealed that the chemistry lab routinely
reported values for Strontium isotopes
that were low by more than
a
factor of 2.
In addition, Iron-55 agreement
was poor.
This was
identified in a March 1984 corporate audit.
Results of an NRC cross
check sample recently completed did not show improvement.
The licensee indicated that they were aware of this problem and had
initiated several
actions to improve their performance in this area.
At the exit interview, the licensee
repres'entative
committed to
provide
a written submittal to the
NRC describing the plan to
improve performance in this area.
Audits
Annual audits required by TS'6;5.2.8.j,
k-, l and
m were verified to
have been performed or scheduled
as required.
An audit performed in
1984 to meet the requirement of 6.5.2:8'.j
and

exami'ned by the
inspector.
The audit appeared
comprehensive in scope,
concerns
and
quality findings were identified, these'ere
responded
to by audited
organizations.
Corrective actions
were examined
and".accepted
by the
auditing organization.

were also identified to and discussed
with licensee
personnel during the inspection.
In the case of concern
14 regarding inter laboratory cross-checks
discussed
in section
h of this paragraph,
the corrective action had
not been totally effective for Strontium analyses.
An audit of ODCM implementation required
on
a bi-annual frequency,
and the annual audit of quality assurance
for effluent and
environmental monitoring was being performed during this inspection
period.
The inspector attended

a review of past experience
and training was not being
performed by both the Department
Manager
and the Plant Training
Coordinator
as described in FSAR Chapter
13 Section 13.2.2.C,
"Requalification and Replacement
Training for Other Plant Personnel
(Maintenance,
HP/Chemistry, Technical)."
At present,
the licensee
department
managers
have the responsibility for reviewing past
experience
and training of replacement
personnel
and determining
required training commensurate
with job duties.
The licensee
has
committed to review and take actions to correct this conflict.
No violations for deviations
were identified.
b.
Maintenance Trainin
The inspector
reviewed the licensee training program for maintenance
personnel.
The inspector's
review consisted of discussions
with
supervisors
and personnel
responsible for program implementation
and
a tour of the maintenance
training building.
The inspector
determined that the licensee's
maintenance
training program required
the appropriate training and refresher training commensurate
with
job duties.
The training department
consists
of many electrical,
instrument,
and mechanical visual aids to assist
the instructor in
training.

Overall the system operating procedures
appeared
to be adequate
for
use by properly trained
and qualified individuals.
Detailed information and quality of the procedures
varied.
The HPCS
procedure
was found to be more detailed,
informative and consistent
with other available
documents;
than the
RHR procedure
seemed
to
include only that information required to accomplish the designated
activities.
The inspector indicated to the licensee
representatives
that the
HPCS procedure
was more in line with what the inspector
considered
as
a good procedure
and the KB procedure
was
one of low quality.
The inspector also indicated that discussions
with responsible
personnel indicated differing opinions
as to the level of detail
expected
to be included in a system operating procedure.
The
licensee
indicated that this subject material would be addressed
in
a timely manner to assure all individuals responsible for
preparation,
review and approval would be cognizant, of managements
expectations in this area.
The inspector also directed the licensee attention to a precaution
in the
RHR procedure
which requires
the Reactor Operator to hold the
pump switch in the stop position during an electrical power
interruption when the system is in the shutdown cooling mode of
operation.
This action is to preclude
a water hammer event in case
the coolant level in the
RHR heat exchanger
had dropped.
The
inspector questioned
the practicability and appropriateness
of the
procedural solution to the potential problem on
a long-term basis.
The licensee
indicated the matter would be evaluated
to determine if
a design
change to the system would be more appropriate
to preclude
such
an event.
The procedure for controlling deviations to established
plant
operating procedures
provides that other persons
may verify their
copies of procedure deviations against
the master maintained by the
administrative
department
or the copy in the control room.
The
inspector
observed that the control room',copy of deviation forms are
not replaced
by copies bearing the management
signed
forms showing
that the required
subsequent
review and approval of the deviation,
unless
the original was
changed in which case,
the signed
changed
form is filed in the control, room.
The licensee
representatives
indicated that the matter would be ev'aluated
and necessary
measures
initiated, if appropriate,
to assure that .verification of other
procedures
are against
the latest
approved revisions.

The inspector
examined the caution tags
on the reactor control
panels.
All tags were found to be consistent with plant procedure
requirements.
The Reactor Operators
who interfaced with the inspectors
during the
examination of the procedures,
demonstrated
a high proficiency in
their knowledge of the plant systems
and
how the various
documents
inter-related.

Assurance Audit Pro
ram
Records
and procedures
of the (}uality Assurance
(gA) audit program were
examined for the year 1984,
and discussions
relating thereto
were held
with QA management
and audit personnel.
The following observations
and
findings resulted.
I
a.
Sco
e and Schedule of Audits
gA audits
are scheduled
on a calendar year basis.
The proposed
audit schedule is developed
by the gA,'audit staff,
and subsequently
presented
to the Corporate Nuclear'afety Review Board
{CNSRB) for
review and discussion pri'or to'pproval by management:,
During 1984
a total of 14 audits
were conducted of activities at
WNP-2.
The scope of activities subjected 'to audit, in'eluded 'all
those which are required by the facility t.'echnical s'pecifications
to
be performed under cognizance
of the
CNSRB;
As such,
the scope of
audits
covers the performance,
training and qualifications of WNP-2
operations staff as well as support organizations
and the oversight
and review committees
required of the technical specifications.
b.
ualifications of Audit Personnel
Records of the qualifications of audit personnel
were examined
and
found to be in accordance
with applicable industry and regulatory
standards
for such personnel.
C.
Documentation
and Resolution of Audit Pindin

Reports of gA audits
were selectively examined in detail for the
year
1984.
The reports reflected
a well planned
and thorough audit
process.
Deficiencies,
when identified within the organizations
or
activities audited were clearly documented in terms of those

conditions not conforming to licensee
imposed or applicable
regulatory requirements.
The audit findings were directed to appropriate
management
levels of
the organizations
audited for formal (written) response
and
resolution.
A goal of 120 days,
from the time of identification of adverse audit
finding to resolution
and closeout,
has
been established
by QA
management.
For the period 1984, the average period for closeout of
audit findings was
123 days - closely approaching
the goal
established.
To closeout
an audit finding the
QA staff carefully
evaluates
the management written response
for adequacy in terms of
not only correcting the deficient condition but also steps
proposed
to prevent recurrence.
Records revealed it not unusual for the
staff to find the initial response
to audit findings to be
unacceptable,
requiring additional response
'by the management
of the
organization audited.
After reaching satisfactory resolution in the written response(s)
to
the audit findings, the
QA staff verifies implementation of
corrective actions generally through reaudit,,prior to final
closeout of audit findings.
I

As
a part of each audit the QA'taff, in addition to documenting
specific adverse
findings wher'e applicable,
makes
a determination of
the overall effectiveness,'of the',activity'audited'.
This
determination is documented in the repor't of the audit, thus
providing an overall assessment.
of the effectiveness
of activities
and organizations
audited for senior licensee
management.

No violations or deviations from NRC requirements,
were identified
within the
QA audit program activities e'xamined.
It.was concluded
that
a viable and effective. QA audit program had been
implemented
with regard to operational activities at the VNP-2 facility, and
that the program enjoys healthy support of senior licensee
management.
No violations or deviations
were identified.

On April 19 and 26,
1985,
an exit meeting
was conducted with the licensee
representatives
identified in paragraph
A.
The inspectors
summarized
the
scope of the inspection
and findings as describe in this report.
The
licensee
acknowledged
the violations identified in the areas of control
of M&TE, the offsite committee,
the onsite committee,
and primary
containment integrity.
