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).
AP-5.0 -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 Actions taken to bypass maintain oz p 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.
Repair Component/Part 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." Keywords:
Repair, fix, refurbish, clean, reinstall, rebuild, reset.
AP-5.0 -36 February 1986
e APPENDIX C NPRDS CODES NPRDS CORRECTIVE ACTION CODE (Cont.d)
Replace Parts A piece component or part is removed and a similar or identical part is put in its place. An example of this is "Installed new valve stem and seat in accordance to original specifications."
Key words: Replace, install, repair, fix, rebuild, added, refurbish.
Replace Component To replace the entire component with a similar or identical component. For example, "Replaced defective Rosemonnt Pressure Transmitter on Feed water line with an identical unit." Keywords:
Replace, install, repair, fix, rebuild, added, refurbish.
AP-5.0'37 February 1986
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.
Weld Related Weld fracture, 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.
AP-5.0 -38 February 1986
APPENDIX C NPRDS CODES NPRDS CAUSE OF FAILURE CODE (Cont.d)
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.
