(Reference SER/ER Change Notice, No. 811).
Revise Paragraph 3.5 as follows:
3.5 Manufacturer's and ANSI N45.2.2-1978 Recommendations:
Maintenance recommendations furnished by the Manufacturer or included in ANSI Standard N45.2.2-1978 provide a basis for the development of the preventive maintenance plan for any equipment.
These recommendations have been established primarily to ;revent or detect moisture induced corrosion damage or insulation degradation.
The preventive maintenances specified by the Manufacturer or contained within the Standard are generally very conservative due to the assumption that worst case ANSI N45.2.2 Level B Storage conditions could prevail at the storage location.
At WNP-3, equipment located indoors is being maintained in an environment that is in most cases better than that assumed by the Manufacturer or those who prepared the Standard.
In the case of the RAB/RB superstructure, the environment is substantially more benign than that projected.
In f act, in this Category I environment, as discussed in Paragraph 3.3.1, moisture induced degradation has been shown to be no concern.
Accordingly, preventive maintenance measures required to prevent equipment deterioration at WNP-3 are less stringent than those requirements specified by the Manufacturer or contained within the Standard.
In Appendix A,
standard maintenance requirements are specified by equipment type.
The maintenance specified is commensurate with the need for protection from the environment.
For the reasons discussed above, the requirements contained within Appendix A and implemented through the Scheduled Maintenance System, will differ from those of the Manufacturer or the Standard.
For example, if the basis for a raintenance recommendation is to prevent / detect carbon steel corrosion or insulation degradation, this recommendation may not be followed for equipment within Category I or II areas where it has been shown that these inspection / protection measures are not warranted.
- Unless otherwise stated, smendment stfects this revision and succeeding revisions.

v.7 WNP-3 PRESERVATION OF ASSETS PROGRAM STATEMENT i
- 1. 0' INTRODUCTION The WNP-3 Preservation of Assets Program for the preservation period, was-developed to ensure that permanent plant and construction facility structures,' systems and components, are preserved and maintained, with
.the' required records
- stored, such that plant licensability is retained:
and economic risk is minimized.
The Preservation of Assets Program at the WNP-3 Project' falls:under the.
Quality Assurance Program Descriptions as delineated in Chapter 17 of the 1
FSAR.
Preservation Engineering has the overall responsibility for the-H Program.
This program was initiated in 1983, when construction was delayed.
It has been refined periodically as the project " ramped down" and a steady state preservation mode was attained. The program was rewritten in 1988, 1989 and 1990 to incorporate the following changes.
o A clarification of how preservation and preventive maintenance tasks 7
o pl na f
C Site Organization Program (Supply System and Ebasco)'.
I o Inclusion of assets which are in operating status.
=i o Improved permanent building environmental conditions as a result of improved building closures and heat additions'.
o-Experience gained since the start of the program, including the need
}
for, and effectiveness of, vapor phase inhibitors (VPIs).
~
jl 0 Establishment -of the Corrosion Monitoring Program (CMP) as quality l
.affecting and requiring more rigid requirements for documenting, j
' tracking, and closing CMP walkdown inspection items.
j This program covers all permanent plant assets and selected nonpermanent property and equipment that is required for construction completion.
1 WMC 051 consists of this Program Statement and four appendices whi.ch provide detailed direction on implementing the overall program.
The appendices are:

WNP-3 PRESERVATION OF ASSETS PROGRAM STATEMENT Appendix B WNP 3 Structural Material Corrosion Monitoring Program (CMP)
Appendix C Hygrothermograph Plant Monitoring Appendix 0 Electrical and Electronic Components 2.0 OBJECTIVE 2.1 The-objective of this -document and its appendices is to define a-Preservation of Assets Program which will optimize the preservation of plant equipment and structures while considering the preser-vation period constraints.
.The program is designed to-protect materials, equipment, components, systems,- and structures from.
. adverse environmental conditions whether in storage or installed.
The program is also designed to maintain the life and reliability of equipment within operating systems.
2.2 The program objective will be achieved by implementing the-following basic actions.
2.2.1 Establishing and maintaining procedures for controlling and documenting changes to the preventive maintenance and inspection requirements carried over from the Construction phase.
2.2.2 Establishing standardized long term preservation require-ments:by equipment type.
2.2.3 Improving permanent building environments to minimize corrosion induced by' atmospheric conditions and prevent condensation-This is accomplished by heat additions which lower humid " 4 and stabilize building temperatures.
Closure of ca,struction openings is also emphasized.
2.2.4 Monitoring building temperature and humidity conditions and implementing adjustments necessary to achieve an optimum
-environment.
2.2.5 Performing inspections of plant equipment and structures for corrosion -degradation or conditions conducive to corrosion.
2.2.6 Monitoring indoor and outdoor corrosion rates by placing corrosion test coupons of actual or typical plant materials at selected locations at WNP-3.

2.2.7 Modifying Construction' phase preventive maintenance actions or inspections where supported by preservation results and engineering review.

Most of the plant components are in place and systems are. partially complete.
. Portions of the Fire Protection System, the Nitrogen-
~

- System, the HVAC-System, Turbine Lube Oil
- System, Electrical Distribution System :and Makeup Water System _have been placed in l
operation.
3.2 Duration of Preservation Period
'This maintenance program is predicated on an extended preservation-
_I period -which with an ongoing review is considered. adequate for an indefinate period.
3.3 Site / Plant Environmental Conditions and Preservation Philosophy j
-i X
Local weather is characteristic of a mid-latitude coastal environ-ment.
Temperatures are stable with mild seasonal: and diurnal: tem-perature variations.
The site' experiences approximately 60 inches
- rainfall per year and high humidity-: levels approximately 9 months of the year.
During the preservation' period the environment within-the plant structures is more benign than that encountered in the i
construction phase.
It is intended that doors and outside openings be closed and - areas be draft free with clean floors, resulting in j
no appreciable airborne contamination. This environment has also improved since the first -years of the preservation period as a result of better closures of openings to the outside environment,
~
jl the addition of electrical unit' heaters, and less' activity within the-buildings.
As part of-the Preservation Program, the temper-ature and humidity conditions in the plant buildings are monitored' i
and docunented (See Appendix C).
Also through _the. Corrosion i
~
Monitoring ~ Program.(See Appendix B) the plant is monitored for the y
a potential for or actual occurrence of corrosion induced by i
atmospheric conditions.
In order to optimize the Preventive Maintenance Program and to assure maintenance efforts are directed-at areas nf greatest concern, the permanent plant building and
- l yard / roof areas have been classified with regard to the need-for protection from the environment.
This is primarily protection of equipment and structures from moisture caused corrosion and h
electrical equipment insulation degradation.
The four environ-mental categories that have been established are:

Cat p ry 1
- Inside the RAB/RB Superstructure.
No protection from the environment-required.
o Category II
- Inside Heated Buildings Other.Than the RAB/RB Superstructure.
Minimal' protection ~.from the environment required, o
Category 111 - Inside Unheated Buildings.
Protection required a
for sensitive items, o
Category IV - Outdoors (any area which is directly exposed to j
.the outside environment).
Significant pro-tection required for most items.
3.3.1 Category I, Inside the RAB/RB Superstructure Most of -the plant's installed QCI equipment is located in this-area,.and during suspension special emphasis has;been placed on stabilizing this environment. The preservation s
goal ha:: been to establish stable daily temperatures. and average relative humidities of 50% or less.
In 1989 the Project recognized the achievement of.this preservation goal and the resulting benign environment.
Supporting this-
]'
assessment were results from Corrosion-Monitoring Program-walkdowns and supplemental assessments'that'had not found-i
.any indication that corrosion. is active.-
Similarly, polished carbon steel surfaces. throughout the super-structure continue to - show - no signs: of, corrosion -after-6
- i years of preservation. The. evaluation _of. this data and the Z
observations, inspections,"and tests made to date indicates N
that corrosion will not progress and electrical insulation will' not degrade in the RAB/RB superstructure with its current environmental. conditions.
This evaluation-for atmospheric corrosion.is. consistent with the position established -in' Appendix B that atmospheric corrosion will l
usually not be observed at relative humidities below 50%
(Ref. Paragraph II, 1)).
E In recognition of this benign environment, the preservation philosophy within~ the RAB/RB superstructure was adjusted.
Periodic equipment inspections / tests. for moisture induced degradation were curtailed,. deleted or transferred to surveillances under the Corrosion Monitoring Program.
Air j
exchange between the equipment. internals and the area environment were promoted.
Access openings were screened instead of being sealed.
The need for most s,upplemental corrosion protection measures,wat eli'minated..
- However, based on manufacturer's recommendations and a conservative i
approach some previously established measures were WMC-051 Rev 5 LO4/02/90 4 of 13 4

continued.
Examples are; supplemental heat for the_ diesel generator, nitrogea purge for the Primary NSSS system, air i
conditioning for the control room and. relay _ rooms and application of preservatives to machined surfaces..
The Category I environment is similar to a Level A storage -
environment as defined in ANSI N45.2.2
-1978Property "ANSI code" (as page type) with input value "ANSI N45.2.2</br></br>-1978" contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process..
3.3.2 Category II, _Inside Heated' Buildings Other Than the RAB/RB Superstructure Like the RAB/RB, efforts made during preservaticn have significantly improved the environment within other heated buildings from that which was present during construction.
In these buildings minimal corrosion has been observed.
Recent Corrosion Monitoring Program Walkdowns and' the Preservation Assessments have not found any indication that corrosion is active.
Polished carbon steel surfaces show no signs of corrosion after six years of preservation.,
Hygrothermograph data for the Turbine Building shows that 1
v temperatures and relative humidity fluctuate-closely with j
respect to changes in the outdoor environment.
- However, l
relative humidity remains controlled relative.to the i
outdoors with monthly mean relative humidity averaging-62%.
Other heated buildings in this. category should exhibit similar environmental conditions.
a The preservation philosophy for Category 11 environments ~is j
similar to the: RAB/RB except there is greater. use of l'
supplemental heat and shrouds to -protect sensitive
+.
equipment.
- Also, equipment internals generally remain-sealed to the area environment..In the Turbine: Building special measures (nitrogen and dehumidified: air) are used to protect the Turbine, the Main Generator and th'e Exciter.
The Category 11 environment is similar to a Level 8 storage

-3.3.3 Category 111', inside Unheated Buildings
[
Inside unheated buildings, temperature and humidity mirror l
the outdoor environment.
Atmospheric corrosion of carbon steel will occur if not prevented by use of preservatives or coatings.
In most cases, light atmospheric corrosion is not damaging.
Formation of oxide films tend to slow:
corrosion on most materials.
Sensitive equipment and' unprotected machined surfaces must be protec.ted from this environment by use of preservatives, coatings, -heat addition and shrouding as appropriate.

The category til environment is similar' to -a Level C storage environment as defined in ANSI N45.2.2.
- Usually, protective measures are necessary for. equipment requiring heated Level B storage as. described in ANSI N45.2.2 - 1978.
3.3.4
. Category IV, Outdoor q
It has. been found that most equipment and structures exposed to WNP-3's outdoor environment require protection through coverings,
- coatings, heat and preservatives'.
Periodic inspections are made of the plant buildings, roofs
~
and drainage systems -to identify problems and initiate.
I corrective-action.
As' the~ preservation -period has
. lengthened, the need for more. extensive preservation' 4
measures has been recognized.
The current preservation-philosophy is focused on preventing standing water in-equipment and on structures and stored materials.
Also, as-a result:
of inspection findings, more frequent 'and T
extensive internal-inspections. of equipment have been implemented.
Similarly, a program for periodic reappli-cation of coatings and preservatives has been established.
4 Shrouds have been upgraded or added to provide additional protection for. equipment.
The Category IV environment-is similar to a Level D storage -
l
-environment as defined in ANSI N45.2.2 - 1978. ~ Protective 1
measures are required. for installed equipment which would require inside storage, level B or C.
4 3.4
.Use of Vapor Phase Inhibitors (VPIs) 7 Vapor Phase Inhibitors have been placed within closed atmospheres of equipment to inhibit corrosion.
Application of these inhibitors are'now evaluated on a case-by-case basis (Reference 3-PEM-89-13).
Vapor phase inhibitors are not approved for use on NSSS primary coolant wetted systems or the secondary side of the steam genera-tor.
Use of VPI on any component which may feed into either of the
-above systems requires that 'the component be isolatable from' the restricted areas of these systems, both during use and during-future flushing of the components at the end of the preservation L
period.

WNP-3 PRESERVATION OF ASSETS PROGRAM STATEMENT A
3.5-l Manufacturer's Recommendations Maintenance recommendations furnished by the manufacturer provide a i
bi asis for the preventive maintenance plan for any equipment.
- iHowever, the recommendations provided may be very conservative and not intended for an extended period of storage or in the non-V operational. installed state.
Accordingly, preventive' maintenance-specified for any equipment may differ from manufacturer's.
instructions es provided for _in Section 4.2.
Deviations fromt 1
manufacturer's requirements will frequently be based on an environmental justification.
For example, if _the basis for a manufacturer's maintenance recommendation is to prevent / detect either carbon steel corrosion or - insulation degradation, this 1
-recommendation _may not -be followed within Category I or II. areas where it has been shown that these_ inspection / protection measures
-are not warranted.
4.0 MAINTENANCE RE0VIREMENTS 4.1 Preventive Maintenance Preventive maintenance consists of those activities which inspect, monitor,
- surveil, or perform-work to preserve equipment and structures.
These activities include sucht items as visual
- checks, shaft rotations, insulation resistance-
- testing, instrument surveillance, application of internal and external preservatives, etc.-
4.2 Preventive Maintenance Reauirements 4 ~. 2.1 The preventive maintenance required for any equipment or structure is the sum of the tasks which are contained within the Scheduled Maintenance System--(SMS) for that equipment or structure. These tasks _ are developed from:
a)
Manufacturers' requirements, b)
Appendix A,
Preventive Maintenance Requirements by Equipment Type
( Applicable only as a guideline to non-permanent plant),
c)
Documented engineering evaluations of the preservation requirements for permanent pl ant and selected construction assets.
d)
Plant Preservation Manager / Supervisors evaluation of the preservation and operating requirements of any piece of equipment or structure.

Documented Engineering review -is. required for variations from-manufacturer's ~ requirements for permanent plant' assets.-
When preventive maintenance is performed' in accordance with' the standardized requirements' of Appendix-Ai -the review and' approval. of Appendix A satisfies this requirement.-
For construction assets, selected review will i
be provided as defined by the-implementing procedures.-
t 4.2.3 Most of the initial ~. preventive maintenance-requirements' included in the SMS system were. developed during:the con -
o struction ahase of the Project..
When construction was-
- delayed, t7e construction preventive maintenance require-ments 'were t'ransformed into. the ' Scheduled. Maintenance System-(SMS).
During-preservation SMS requirementszhave e
been modified'to reflect the improved building. environments

reviews of SMS tasks and performance thereof to monitor-program effectiveness.
4.3-Preventive Maintenance Reovirements by Eouioment Tvoe - Append'ix A provides the standardized requirements for ' preservation and-j preventive maintenance of stored or installed permanent plant equipment by type.
Appendix A covers only general equipment types,
'i.e.
- tanks, pumps, panels,- motors, etc. which usually have been J
supplied by mul tiple manufacturers.
Appendix A was= originally y
established-to standardize preventive maintenance requirements 4
implemented in the, construction phase and to provide supplemental requirements for long-term preservation.
Over -time, thesa standardized requirements have been modified to reflect:
o The establishment of improved building environments, o
Inspection results (both positive and negative),
o lessons learned, o Engineering evaluations performed.

5.1.
The Corrosion Monitoring Program as described in Appendix B f
consists of the following activities:
}
5.1.1 The establishment of' corrosion baseline data.by visually inspecting plant equipment and documenting current condi-tions for future reference points.
Preventive' maintenance i
inspections by the preservation maintenance group also provide baseline data for. use in evaluating-the effec-tiveness of corrosion prevention.
5.1.2 Corrosion test racks have been placed in the-field and in-i the buildings.
The corrosion coupon materials used are representative of actual pl ant components (i.e.,
NSSS vessels and
- piping, anchor bolting, equipment ' bolts, reinforcement bar, tanks, pumps and stiff clamps).
Coupons' 1
are monitored for both uniform galvanic and pitting types of corrosion.
The results of the qualitative and quanti-r tative corrosion sampling shall be considered.'in the on-going review of preventive maintenance practices..

5.1.3 Semiannual inspections (CMP Walkdowns).
These inspections are: performed in order to monitor the effectiveness of corrosion prevention as well as to identify atmospheric conditions within the plant conducive to corrosion and the effectiveness of closures to the outside environment.
In addition, test coupons and plant components / materials are inspected for corrosion degradation.
5.1.4-The plant cathodic protection systems are monitored on a-regular basis to assure their effectiveness.
The moni-toring ' includes rectifier checks and benchmark potential
- checks, a cathodic protection survey of the underground piping systems is also performed periodically.
5.2-Findings from the above activities are documented to provide input to the_ Plant-Preservation Program.
6.0 HYGROTHERMOGRAPH' PLANT MONITORING 6.1 Temperature / humidity monitoring is an integral part of the overall preservation and ' preventive maintenance requirements.
The record of actual-temperature / humidity conditions encountered aid in-providing assurance that the objectives of the Preservation Program 3
are being met.
6.2 Hygrothermograph pl ant monitoring as-described in Appendix C,
provides data to indicate the environment the equipment, systems,
' components and structures have experienced diring the preservation period.
The monitoring program also provides a warning of changes
~in environmental conditions with the potential to lead' to equipment damage.
Corrective measures, such as changes in preventive main-tenance requirements, will then be-taken.
6.3 The records of the monitoring program' are also available as evidence of the environment during the preservation period which may be used in part to justify changes to intervals in equipment g.
overhaul periods.
7.0 ELECTRICAL AND ELECTRONIC COMPONENT MONITORING 1
The-Preservation Program for electrical = and electronic components is described in Appendix D and as such, is an integral part of the WNP-3 Preservation of Assets Program. The basic concept adopted is to maintain.
the components warm, dry and clean, consistent with ANSI Level B
requirements.

Appendix A,
Preventive Maintenance Requirements By Equipment Type, is an
' integral part of WNP-3's Preservation of Assets Program..It has been developed to establish standardized preventive maintenance requirements for. generic classes of permanent plant equipment.
Appendix A primarily addresses preventive maintenance requirements for equipment which is in.
storage-or installed, but for. some equipment types, operational mainte-naace -requirements are-also included.
In 1990, Appendix A was expanded; to. cover more equipment types and to provide the. basis for and greater detail on the requirements necessary for preservation.
In addition, different levels of maintenance were established by equip'-
ment type.
These levels of maintenance are. commensurate with the.
specific need imposed by each different environmental condition in the plant and outdoor areas to which the. equipment is exposed.
II.
OBJECTIVES The objective of this appendix is to establish standardized maintenance requirements for.
the general types of permanent plant equipment.
Implementation of these standardized. requirements for maintenance in-conjunction with other attributes of the WMC-051 Program will maximize the continuing functionality of the equipment while minimizing the economic risk.
III. APPLICATIONL The standardized requirements included in Appendix A are the basis for preventive maintenance for all equipment contained within each equipment-type.
However, in accordance with the Program Statement, Paragraph 4.2, deviations are permitted for specific equipment.from those requirements -
specified in Appendix A.
Also, when applying Appendix A requirements, care must be.taken to ' assure the~ equipment is compatible with the standard maintenance direction.
This review is particularly important for non-standard, unique equipment.
All external and internal. inspections required by this document shall be J
performed per the requirements of CSP-9-02 and any supplemental direction

RE0VIREMENTS BY E0VIPMENT' TYPE l
A.
BASIS.FOR THE STANDARDIZED REQVIREMENTS For each~ ecuipment type included in this Appendix, the basis for the standardizec maintenance is.noted. ;In most applications protection
- of - the equipment from corrosion or other moisture caused degradation.
l is the paramount concern.-
Accordingly, the level of preventive maintenance specified in Appendix A is directly proportional to the severityL of the environment in which the equipment!is located.
The Progra:- Statement, Paragraph -3.3, has classified the plant areas into four environmental categories.
These categories. are used:
throughout-Ap)endix A-to specify
' preventive maintenance ~
requirements.
Tie four categories are:
Category-I
- Inside the-RAB/RB Superstructure..No protection from the environment required.
Category II. - Inside Heated Buildings Other Than the RAB/RB Superstructures.
. Minimal protection from the environment required.
I Category'III-- Inside' Unheated Buildings.
Protection required for sensitive items.
Category IV - Outdoors '(any area which is directly exposed to the outside environment).
. Significant-protection' required for most items.

'Iherefore,.the bulk of thei coupons are carbon steel alloys.
'Ihe coupons are prepared fr m, metals selected to represent >
actual plant structural steel and piping, NSSS vawls, rebar ard nuts, auxhor bolting' and structural bolting. 'Ihe alloys-used. in the coupons testing are A-105, A-36, A-533 Gr. B Class ~
2, C-1045, C-1141 and C-4140,.17-4 PH, type'304-SS, A-5271-and A-471 Cl 5.
Plain carbon steel atmospheric corrosion rates are expected to -
range -between 0.6 and 1.3 mpy (mils per year) where the relative
~ average humidity is greater than 60%. High-strength low-alloy carbon: steele are expected to. corrode at a rate of_0.3 mpy..
Atmosoberic corrosion rates--for stainless steel, aluminum,-
4 copper, and zinc coated materials are approximately 0.011,' O.03, 0.023, 0.08 mpy respectivetly.

'Ibst racks are classified as either field racks, building racks or supplemental locations for coupon holders. 'Ihe racks are
[
j either cenred to a permanent wall attachment (as in the case of o fi most building racks) or are tenporarily positioned in side plant equipment, which has been tagged on.the outside..
Initially, field -test racks. contain.up to 40 coupons and building test -racks contain up to 6 coupons. Tables I and III identify the initial field and. building test rack ocupon l-materials and the rack locations. - Supplemental test. coupons are i
f described and test racks locations identified in Table II.
l
- Ibe outdoor field test racks are designed to keep the lowest e
W aans at least 30 inches above the ground-and clear of p
weeds, brush arxi. debris.
Since most of the published data on QJ atmospheric corrosion is based on a 30 degree angle with'the horizontal,. an approximately :30 degree.. angle ~ is used on the l
field test racks. One field test rack is modified with a hanger to susperxi 12 inch lengths of reinforcement bar. Two additional
(
coupon racks are placed inside a capped spool piece on a length of angle iron.
In addition to the field and building test
- racks, four pipe plugs are modified with a nylon post to support a corrosion coupon.

INIRXUCTICN We Preservation Fiwtait for Electrical and Electronic Cuigrists is an integral part of the WNP-3 Preservation of Assets Fivyt-u..
Consideration within : this prvyt-u for these wi,cs tus is based upon the uncertainty relative to the 1erugth of time associated with the preservation. period ard the effect that time in layqp status may have l
on the efficiency of the associated I&C elements. We -w-As under consideration are those electrical and electronic cui,crets which have been installed in the plant and are in a layup status.
We four elements that lead to degradation of electrical and electronic cuitcrents are:
a)
Ihysical damage, including direct inpingement by water, ard l
exposure to electrical pcwer surges.
b)
Airborne contaminates such as dust, grit, and corrosive chemicals.
c)
Excessive tanperatures, either high or law, and associated thermal stre.sses.
d)
Lcoessive humidity which can lead to noisture deposition thrcogh
'r condensation.
he basic uagt adopted is to maintain the cuigents warn, dry ard clean consistent with ANSI level B requirements. 'Ihis ocupled with a limited monitoring activity forms the basis of this prvyt u.
Normal aging. of cui,crents from the passage of time cannot be pre-l Vented.
Some no,.w.1 maintenance cuigents such as "O" ring seals can be expected to harden ard W brittle and will require replacement M
during the calibration phase of the startup activities..
It is recognized that individual protection of each cuigt.sent is not cost effective.
It should also be noted that this pavwtam add m c only the preservation activities required as a minimum and sourd engi-neering jt*yawnt should be anployed in the inplementation of.
certified vendors' rs.a.mmardations that go beyond this prwt ain.
II.
OBJECTIVE 2e objective of this program is to improve ard maintain the environ-mental corditions for the electrical ard electronic ocarponents during the preservation period. In addition to this, the limited monitoring l
program is intended to provide indication as to the adequacy of such efforts.
