FIGURE 4 MAINTENANCEEVALUATIONREPORT INITIALDETERMINATION Inspection of ASME Section XI component indicates that only minor repairs as specified in Step 311. are required to effect the.
necessary restoration.
GYes 0 No IfNO, answer Questions 1 thru 6.
MAINTENANCEEVALUATION 1.
Was component/item damaged as a result of foreign particle inclusion? {weld slag, debris, etc.)
2.

APPENDIX C NPRDS CODES NPRDS FAILURE SYMPTOM CODE The code indicating the first effect of the failure observed when the failure was discovered.
Choose one of the following:
A - Physical Fault-A failure is characterized by a changed physical condit1on, physical configuration, fracture or
- damage, often resulting in a loss of integrity or ability to hold a
contained fluid or electrical cu'rrent.
This category includes blocked or stopped
- flow, cracks, fractures or
- breaks, collapses, physical distort1on or displacement, electrical
- arcing, open
- circuit, shorts, or degraded 1nsulation.
Leaks are considered a
special category (E or F below) due to the number of reported items.
B Out of Spec1fication A failure is characterized by operation outside the permissible range of expected output or response.
This category inc1udes out of limits, low or high output or
- flow, erratic
- output, premature
- response, off frequency, off voltage, intermittent operation or failure to synchronize or control.
C - Demand Fault failure 1s characterized by the responsible system or component failure to actuate,
- move, or change operating mode upon
- request, either operator-init1ated or from an automatic signal.
This category includes failure to
- stop, close,
- open, release,
- run, start/move, operate per
- demand, respond,
- record, or instances of no output when an input of some sort demands one D Abnormal Character1st1c-A failure is characterized by a
type of response or an operating characteristic not considered normal or expected.
This category inc1udes such attributes as overheating, unusual noise or vibration,
- chatter, corrosion, discoloration, and false response (such as non-zero output with zero input).
-34 February 1986
APPENDIX C NPRDS CODES NPRDS FAILURE SYMPTOM CODES (Cont.d)
E - Released Leakage -
A failure is indicated by external leakage of a
process fluid from within its normal pressure boundary.
This includes leaks to the environment caused by faulty packing glands, mechanical
- seals, or gasketed joints.
Also included in this category are relief valve leakage and heat exchanger tube leaks.
F Contained Leakage - A failure is characterized by leakage of the process fluid through a
closed isolation device (e.g.,
a valve) and along a normal flow path.
This inc1udes internal flow leaks such as across valve seats.
Not included (see code E) are relief valve leaks and heat exchanger tube leaks.
I AP-5.0
-35 February 1986
APPENDIX C NPRDS CODES NPRDS CORRECTIVE ACTION CODE The following is a listing of the codes used for corrective action taken to remedy a failure, along with a definition and an example for each of the codes.
Recalibrate/Adjust To reset a
device mechanically or electrically to a
prescribed valve or position.
An example of this is to calibrate an instrument string.
Specifically it would read something
- like, "Reset outputs of the flow transmitter on the shaft driven feed water pump flow instrument loop".
Some keywords to look for:
calibrate, recalibrate, ad)ust,
- readjust, set, reset.
AC Temporary Measures Repair Component/Part Actions taken to bypass maintain p oz restore a
system or component to operation for an interim period.
An example of this is to replace a
defective part with another component until either conditions permit a proper replacement, or a similar component can be purchased.
For
- example, "Added temporary pressure gauge on feedwater heater high level trip column, until.
next outage when a proper gauge can be installed".
The Key word here is:
Temporary.
To refurbish and/or reinstall a
component, including such actions as cleaning and or polishing.
An example of this would read something
- like, "Fixed circuit breaker coil and cleaned contacts for diesel generator air start compzessor motor starter."

APPENDIX C NPRDS CODES NPRDS CAUSE OF FAILURE CODE MECHANICAL CAUS ES Foreign/Incorrect Material Material not as spec1fied or internal environment containing an unanticipated material (e.g., water).
Particulate Contamination Gas or fluid
- contents, including unexpected buildup of suspended solids.
Normal/Abnormal Wear - Loss of function due to a
gradual loss of configuration or material.
Lubrication Problem Frictional failure directly attributable to lack of proper lubrication.
- crack, or heat-affected zone failure attr1butable to the fielding process.
AG Abnormal Stress Material stress attributable to abnormal
- load, vibration, temperature, pressure or flow.
AV Connection Defective/Loose Parts Loose mechanical parts or fasteners.
Material Defect Material
- type as specified, but with integrity compromised due to a flaw or leak.
BB Mechanical Damage/Binding Loss of proper mechanical configuration due to excessive forces.
BC Out of Mechanical Adjustment - Loss of proper mechanical al1gnment, movement
- limits, or conf1guration not due to damage.
Loose setscrews,
- locknuts, mechanical
- stops, and setpoints of adjustable fixtures are included.
BD Aging/Cycl1c Fatigue Time-related degradation of mechanical properties without significant loss of material (as through wear).
Includes radiation
- damage, embrittlement, and fatigue cracking of mater1al subjected to stress reversals.
BE Dirty Loss of function due to deposition of extraneous material on operating surfaces such as circuit breaker moving parts, pilot valve
- seats, etc.
BF Blocked/Obstructed - Loss of flow function due to lodged objects or solids.
May also be loss of movement due to mechanical interference other than binding.
BG Corrosion Failure attributable to loss of material or buildup of chemical reaction products from electro-chemical or stress-aided corrosion.

ELECTRICAL/ELECTRONIC CAUSES AG Abnormal Stress Loss of function due to stress-related causes attributable to voltage spikes, oscillations, etc.
Insulation Breakdown
Loss of electrical circuit integrity, including
- shorts, arcs, burned
- windings, etc.,
attributable to failure of the insulation itself.
Short/Grounded -
Loss of electxical circuit integrity due to a
shorted or gxounded circuit.
AT Open Circuit Inopexability of electrical circuit due to a break in conductor or contacts not made up.
AU Contacts Burned/Pitted/Corroded - Inoperability of electrical circuit due to degradation of electrical contacts.
AV Connection Defective/Loose Parts
<< Electrical terminal connection loose, intermittent, or containing high electrical resistance.
Circuit Defective Electrical or electronic circuit fault not attributable to any one subcomponent, component, or part, including unknown electronic faults or failuzes not reproducible.
Burned/Burned Out Loss of e1ectrical cizcuit integrity, including insulation breakdown due to local combustion,
- overload, and/or electrical fire.
Electrical Overload - Loss of function specifically attributable to unanticipated high electrical curxent.
Material Defect - Material type as specified but with integrity compxomised by a flaw.
BE Dirty Loss of function due to deposition of extraneous material on opezating suzfaces such as electrical contacts.
Corrosion Failure attributable to loss of material or buildup of chemical reaction products from electxo-chemical corrosion.

APPENDIX C NPRDS CODES NPRDS CAUSE OF FAILURE CODE {Cont.d)
ADJUSTMENT/HUMAN-RELATED Foreign/Wrong Part - Part does not belong in responsible component or system.
This includes poor designs and misapplications.
Setpoint Drift -
Electronic drift attributable to poor control setpoint stability.
Relief valve setpoint changes during operation due to pilot valve seat bleed rate changes may be included but not changes due to previous repair or mechanical adjustment.
Previous Repair/Installation Status Inadequate repair condition resulting from lack of proper previous maintenance, installation, or restoration to operational status, Incorrect Procedure - Failure directly attributable to an inadequate or improper instruction or approved procedure.
BC Out of MechanicaL Ad)ustment - Loss of proper mechanical alignment, movement
- limits, or configuration not due to damage.
Loose setscrews,
- locknuts, mechanical
- stops, and settings of adjustable fiztures are included.
BH Out of Calibration -
Electrical/mechanical setpoint or= response settings (lead, lag, or reset) not in the specified position or range.
Incorrect Action Loss of proper function directly due to human error.
