FAILURE MODE AND EFFECTS ANALYSIS (FMEA)

3.1 INTRODUCTION

A FMEA is concerned with failure modes in a

system and the subsequent results of these failures.

The FMEA is also useful in providing (1) the basis for a spare parts recommendation and (2) to assist in the development of a planned maintenance program.

I J. 2 PMIS FAILURE MODES Failure points in the PMIS that are considered in the FMEA are I

as follows:

o DAS Multiplexers L

o DAS Processors o

Host Central Processors 1

o Disk Units o

Magnetic Tape Units l

o Dat.s Links l

o Display Consoles a

Hard Copy Terminals o

Power to any Single Device.

3. 3 GENERAL FAILURE MODE EFFECTS 3.3.1 Introduction The PMIS point scans include primary and secondary variaoles.

Primary variables are those monitored variables that provide tne 5

most direct indication needed to assess the status /value of a

safety parameter.

Secondary variables are those monitored variables which provide additional information about a

safety parameter.

The secondary variables provide information to i

perform one or more of the following functions:

l 1.

Determine the cause of the degradation of a safety parameter.

2.

Obtain warning, regarding possible degraoation.

3.

Achieve better resolution in the measurement of :ne safety parameters.

4.

Provides a

means of validation of tne safety parameter status /value determined by the primary variables.

Validation is a procedure designed to increase the assurance that an indicated value represents the true value of a process variable.

Loss of data because of a PMIS failure mode has been minimi:ed by PMIS design.

3.3.2 Loss of Inout Data /Disolau Caoabilitu bu Failure Mooe If it is assumed that all input variable data is present at the input terminals of the PMIS, the data or display capability may

(

be lost by various PMIS failure modes.

These data /disolay l

capability losses may be categorized generally as follows:

1 i

1.

Loss of an individual, signal conditioning amplifier.

Loss of up to eight analog or up to sixteen digital data input variables.

2.

Loss of one multiplexer.

Loss of minimum group of data variables.

Loss of an optical link from one multiple <er cabinet to DAS data concentrator.

Loss of one link out of nine paths.

A redundant path is available.

Minimal data loss.

4.

Loss of one data concentrator.

Loss of nine optical link inputs.

Redundant data concentrator.

Minimal data loss.

5.

Failure of one PMIS computer or disk system.

Redundant computer / disk path available.

Minimal data loss.

6.

A hardware failure in the display data I/O system will fault from one to all displays in the Control Room Displays. TSC, EOF and other PMIS areas.

The display I/O system is redundant, consequently unacceptable display system faults may be bypassed.

No input variables lost.

7.

A hardware failure in the peripheral switch syscem will not fault the display system proper but mau reduce peripheral switching to manual mode.

No redundancy.

No input-variables lost.

G.

Individual display /hardcopy failure.

Loss of l

display /hardcopy only.

No input varianles lost.

In categories 1 and 2 some data will be lost until these single I

point system failures are repaired.

These data losses are partially offset by redundant sensor signals routec into the system by independent signal paths and multiplexers.

Categories 3, 4,

5, and 6 are redundant system paths and cata losses will be minimal in these areas.

Category 7 is a single point failure system where one or more groups of peripherals must be switched ma n u a. l l y.

The peripherals on a system will always be switcha01e or latched on one side of the PMIS computers.

Category 0 is composed of highly redundant display systems and individual display failures do not represent critical losses of capability.

3. 4 SPECIFIC PMIS FAILURE MODE ANALYSIS An objective of the FMEA is to evaluate the reliability /availablity by analyzing the effects of particular failure modes on the PMIS.
3. 4.1 Control Room Area Device Assianment Each of the five IDTS in the control room are served from one of the five DMF32-AD intelligent communications controllers.

To I

fault the Control Room Display System (at least two IDTs operative) four out of five controllers must fail simultaeously.

This is an extremely unlikely event in one path of this redundant system.

The control room display s i g r.a l paths pass througn enree peripheral switch control switches.

In this case two IDTS are I

served by switch 40s two by switch #1 and one by switch #2.

For l

a Control Room Display failure, two out-of-three switc9es.nust fail su.ch that tne IDTs they control are not available to cne Control Room Display System.

More specifically, tne two B

switches must be switch #0 and #1.

Any other combination of two switch failures will leave two IDTs operative which does not constitute a Control Room Display System failure.

A similar situation exists for the Control Room IDT signal patns through the Candalf Rack mounted short-haul modems.

Two of tne IDT signals pass through modem chassis #0s two enrough chassis E

  1. 1 and one through chassis #2.

As a result only a power suoply failure (PS3100) in chassis #0 and #1 simulataneously can fault the Control Room Display System (four out-of-five displays inoperative).

The UNIBUS - 2 interface between the PMIS computer and ene DMF32-AB controllers is the only other failure path in tha control room device I/O system and this module is common to all PMIS displays and hardcopy devices.

3.4.2 Non Control Room Area Device Assianment Failure mode and efforts analysis was used to develop the cevice assignments.

3. 6 PMIS FAILURE MODE ANALYSIS Since the PMIS equipment, is highly
modular, the FMEA was conducted on a

module by module basis in order from the cata acquisition section of the PMIS through the data processing section to the data display / recording system.

The FMEA is concerned wihh failures in all areas of the

PMIS, the effect on the system and system return to normal stacus.

Each time the PMIS fails, a series of steps are requitec to me E

completed to repair or restore the system to its full oprational status again.

These steps include failure detection, fault isolation, disassembly to gain access to the faulty item, repair (or replacement). reassembly and test as shown in Figure 3-3.

Since the PMIS is highly modular, the failed part is locali:ed to a module, that module replaced with a module from spares and I

the failed module sent to a repair shop for offline repair.

Following repair the repaired module is returned to spares.

If the failed part is not a part of a readily removable module, the equipment is taken offline and repaired from repair parts or og vendor service.

The potential failure of each module or equipment is analyzed in Appendix A.

  • From the total failure mode classifications in Table 3-I,::

can be seen that 58 percent of the failure mode classifications occur in a redundant loop of the PMIS configuration.

Forty-two E

percent of the ' failure mode classifications are single point failures but of this 42

percent, 60 percent are minor mode failures and do not require immediate corrective action.

Of the nine critical failure modes eight are in redundant loops of the PMIS and while they require immediate corrective action they do not fault the Control Room Display System.

The one I

single point critical failure is the Star Coupler for which there is no mean time between failure data.

The Star Coupler i s,

however, a

passive device and is not as susceptible to failure as a powered device.

While single point minor failures compose 70 percent of the total minor failures, these failures cover single point failures in the peripheral switch system and non-control room I

display /hardcopy devices.

Seventy percent of the major / minor and major failure modes are E

in redundant loops of the PMIS.

These faults are in Data Acquisition components and display /hardcopy devices which affect the Control Room Display Display System.

E There were no catastrophic PMIS failure modes ioentified.

l II APPENDIX B CONTROL ROOM DISPLAY SYSTEM i

ESTIMATED AVAILABILITY / RELIABILITY The VAX cluster configuration will meet or exceed the following worst case availability analysis.

SAIC has calculated the availability of the SPDS to be the following:

Control Room Display System Availability = 99.90%

Details on these calculations, the MTBF and MTTR used, and clock diagrams are presented in the following.

The MTBF and MTTR for major components in the PMIS are given in Table B-I.

Failure criteria for this analysis is any hardware malfunction which causes a

system or subsystem nonoperable status and creates a requirement for unscheduled maintence.

It is assumed that preventive maintenance will be conducted on a

noninterference

basis, i. e.,

during scheduled shutdowns or during an operating mode without placing the equipment in a nonoperable condition.

Mean Time-to-Repair (MTTR) is defined as the average time to perform corrective maintenance action (a MTTR of four hours was assumed for the PMIS availability calculation).

This time period begins with equipment failure and ends when the equipment is returned to operational status.

It includes time for fault detection, fault isolation, access / secure, maintenance operations (repair or replace), and function testing.

t SCIENCE APPLICATIONS INTERNATIONAL CORPORATION SAIC 19321 10s8/84

r 502-8500108-52 REV LTR B CONTROL ROOM DISPLAY SYSTEM Page B-2 ESTIMATED AVAILABILITY / RELIABILITY 5 April 1986 II Availability is the probability that a system or equipment, when used under specified operational conditions and support environment, will operate satisfactorily at any point in time.

Inherent availability (Ai),

as quantified in this

analysis, assumes an ideal support environment ( i. e., available tools,
spares, trained personnel, etc.)

and excludes preventive maintenance

actions, logistics supply time and administrative downtime.

System success is defined as all data inputs available, and at least one path in all redundant systems is available.

Single point failure items occur in the data input system in the individual data input signal conditioning amplifiers and the associated multiplexers.

These failure points are minimized by redundant signal sources and the proper routing of such signals into the data input system.

A block diagram of the Control Room Display System arranged for availability computations is shown in Figure B-1.

Individual series and redundant path groups are computed on attached data sheets 1 through 6.

System availabilities are as follows:

Data Sheet Unit Availability 1

Data Acquisition System 0.999248 2

Data Processing 0.999941 3

Disk System 0.999797 4

Data I/O 0.999999 5

Peripheral Sw 0.999999 6

Control Room Displays 0.999999 Total Control Room Display System Availability 0.997985

= 99.80%

Since the Control Room Display System is a very redundanc syscem it should be fault tolerant in operation.

APPENDIX C CONTROL ROOM DISPLAY SYSTEM POWER SUPPLY l

l AVAILABILITY / RELIABILITY DATA l

C.1 INTRODUCTION The purpose of this analysis is to determine the reliacility l

provided by an Uninterruptible Power Supply (UPS) as required by reference listed below.

The existing primary power supply system is shown in Figure C-1.

}

C. 2 GENERAL REFERENCE-Letter dated 17 August 1984 to SAI from NPPD.

SUD.JEC T:

SPDS IMPLEMENTATION AUDIT.

With the Uninterruptible Power Supply (UPS) in the PMIS Power l

Supply Configuration as shown in Figure C-1, a high voltage transmission line failure does not interrupt the supply of power to the PMIS.

The UPS has a

battery bank with sufficient capacity to power the PMIS for 30 minutes in a standalone mode.

This time period is sufficient for the emergency diesel power supply to start, warm-up and assume the 125VDC power bus load which includes the battery bank charging load and the PMIS load.

A time flow chart showing the operating and failed conditions for the three PMIS power sources is shown in Figure C-2.

502-S500108-52 REV LTR C CONTROL ROOM DISPLAY SYSTEM POWER SUPPLY Page C-4 GENERAL 6 June 1956 In line A the nigh-voltage transmission line is operating as the prime source of PMIS power until a point in time when tnis source of power is interrupted.

The transmission-line power supply is not available for an average time equal to tne mean time to repair (MTTR) before transmission-line power returns.

In line C, the Emergency Diesel Power System is alerted at line A

failure time.

A time delay elapses until diesel startup (10 seconds) is completed.

Diesel delay time (15 minutes) is I

completed and the diesel power supply System assumes tne 125VDC power bus load.

It may be noted that the right-hand portion of the loop of Figure C-1 is available to supply power to the SPDS power bus in the event of a rectifier or inverter failure in the UPS.

During l

a failure of this type an operational Emergency Diesel Power Supply System is not available to the SPDS power bus and a

transmission line interruption results in a

PMIS

" FAILED" condition.

C. 3 CLASS 1E MULTIPLEXER POWER SUPPLY Appendix C is designed to answer the particular question posed in the reference listed in Section C.2 of Appendix C.

Figure C-1 deals only with the primary power system to the SPDS as this is the part of the total system addressed by the question in the above mentioned reference.

Figure C-1 is, nowever, not the only I

high reliability power supply system serving the PMIS.

This section describes the 1E power supply to the IE multiplexers in the PMIS.

l 5

A block diagram of the IE Multiplexer Power Supply System is shown in Figure C-3.

The system " Start-Up" Transformer is fed from a

345/161 kV transformer to a 161 kV substation, which in turn energizes the system "Startup" Transformer.

This power source is considered to be operating in parallel with an Omaha Public Power District (OPPD) 69 kV power source operating as CNS 's Emergency Power Feed.

THis combination of power sources powers the Division 1 and Division 2 power supply bases.

A Division 1 Diesel Generator is available in cold standby mode as backup for the Division 1 Bus.

Similarly a Division 2 Diesel E

Generator is available as cold standby backup for the Division 2 Bus.

C. 3. 1 CLASS 1E POWER SOURCE RELIABILITY COMPUTATIONS The reliability of the parallel combination of the "Startup" Transformer and the OPPD 69 kV Emergency System is determined from data items (7) and (8) in Table C-1.

The Division 1 Diesel Generator can be considered to be in parallel with the "Startup" Transformer and OPPD Emergency Source if short interruptions (cold standby start to online delays) to the 1E multiplexer are tolerated.

This condition is accepted here.

It will also be necessary to neglect items shown in Figure C-1 for which there is no data in Table C-I.

A mission-time "t" must be selected and one-week or t=168 hours will be selected arbitrarily.
