his calculation is performed as part of the PVNGS response to NRC Inspection Report 90 -121. Pages five,.„d six of that report provide failure data on Holophane, Exide and Emergi-Lite units. The 'data is presented

n a reliability basis, e.g., 4 of 4 Holophane units (100%) failed in Unit 1 in 1988. The conclusion is drawnat the. emergency lighting is not reliable.

ile the failure numbers used by the NRC in the report are an accurate reproduction ofdata provided to theRC in the June 29 1990 letter, their method of portraying failures can be misleading. The purpose of this

tudy is to provide a more proper way of portraying the failures of the Holophane units.

.0 SUMMARY

n average unavailability indicator was developed. The unavailability indicator for each component (andoup of components) is calculated for a specific time period by dividing the total number of unavailable

ays by the total number of days in:the time period. Thus, a value of zero means a component was alwaysyailable. A value of one implies a component was never available. This method is basically the method em-

loyed by INFO (Ref. 1) to monitor the readiness of important safety systems to respond to oK-normal eventsr accidents.'n availability indicator is obtained by subtracting the unavailability from one.

e resulting average availability indicators for the various units and Holophanes as a whole, based on a timeeriod from June 29, 1989 to June 30, 1990 are as follows:

Unit.1: 0,99""'Unit'2:0.95

Unit 3: 0.87

Unit Average: 0.94

.0 "CRITERIAAND ASSUMPTIONS

here are no applicable design criteria, design assumptions, codes, standards, or other requirements for thisalculation. The basic equation used to calculate the average estimated unavailability for a Holophane unit is

o divide the total number of unavailable days by the total number of days in the selected time period

he details involved are described in Section 5.

wo assumptions are made in this calculation. The first assumptions deals with estimating the calendar date

hen the Holophane failed. Following an accepted reliabilityapproach the failure is'assumed to have occurred-'d-poirit between the"last date the'component is known to have been operational and the component failure'."

iscovery date. The second assumption is that is for each Holophane unit there are no failures in the time pe-'od from the last Holophane unit test to 6/30/90. This is the assumption as made for INPO's safety system

navailability monitoring, i.e. ifthe failure is not observed then it assumed that there has not been a failure.

e input data for this calculation is a series of failure data for each Holophane unit that identify the failure disovery date, the component repair date, and the last date that component is know to have been operational. Thisnformation is used to calculate a known unavailable time and an estimated unavailable time as described inection 5.1. The failure data is based on a review ofHolophane work orders performed by an EED Electricalsk force related to Emergency Lighting. A series of graphs were prepared which depict the work order historyfthe Holophane units for the time frame June 29, 1989 to June 30, 1990. These graphs serve as a visual aid

d help document which work orders contain information relating to failure data. They are provided as Ap-endix A.

he failures were compared with Holophane failure evaluations previously described to the NRC in Reference.The results of that comparison follow.

Unit 1: QBN-001 - consistent with Reference 2.

Unit 1: QBN-002 - consistent with Reference 2 -the failure date here is one day earlier than in Reference 2since the that is the day the new batteries were installed.

Unit 1: QBN-003 - consistent with Reference 2.

Unit 1: QBN-004 - consistent with Reference 2.

Unit 2: QBN-001 - consistent with Reference 2.

Unit 2: QBN-002 - consistent with Reference 2 with the following exception. An 8 hour discharge test wassupposed to have occurred prior to Unit 2 restart on 6/29/89, but did not occur until 7/3/90. This is treated as

4 days ofunavailability.

Unit 2: QBN-003 - the failure on 05/11/90 described in Reference 2 has since been reclassified as no failure.

Unit 2: QBN-004 - the failures on 12/29/89 and 5/I I/90 described in Reference 2 have since been reclassi-fied as no failures.

Unit 3: QBN-001 - consistent with Reference 2 with the clarification that the 3-11-90 event is not a failure.

Unit 3: QBN-002 - consistent with previous evaluations.

Unit 3: QBN-003 - consistent with Reference 2.

Unit 3: QBN-004 - consistent with Reference 2.

e failure data is contained in Table 1.

cans a co po ent was neveravai e. is met is asica y t e met emp oy y to momtore readiness important safety systems to respond to off-normal events or accidents.

e method requires the development ofknown and estimated unavailable time periods. The known unavail-ble time periods are the times a component is not available for service when the beginning and ending time ofe unavailability due to a failure are known, i.e. failure discovery time and repair time respectively. The esfi-ated time periods are the average times a component was in a failed state prior to failure discovery. This time

s estimated as one-half time interval measured from the last time the component is know to be operable to theme it is discovered as failed. Thus, for a component which failed an eight-hour discharge test, the estimatednavailable time would probably be one-half the time since the last successful eight-hour discharge test for thatomponent. A more recent preventive maintenance would be used ifa determination could be made that thepecific failure mode would have been detected by the maintenance. The unavailable times described above are

nly those stemming from events judged to be component failures.

.2 Scope

The scope of this evaluation includes all Holophane Units in Units 1, 2, and 3. The time period begins on June

9, 1989 (Unit 2 restart). The process of determining failure dates, repair dates, and last known available dates

equites extensive review of work orders, These work orders are not intended for this purpose and chronologi-al reconstructions can be difficultand time consuming. The selection of 6/29/89 as a start date for this calculaon is based on it being both representative and recent. An end date of 6/30/90 was chosen as the conclusion ofe time period for this study. The basis for the selection of this end date is that it allows for an extended historyithout having to consider open work orders. Although the limited time period is based on time and resource

onstraints, a one-year period is considered adequate to estimate Holophane availability,

.3 Calculation Process

)

e calculation process used is straight-forward. For each failure event, three dates are required as input data:

e failure discovery date, the component repair date, and the last date the component is known to have been

vailable. The time between the failure discovery date and the component repair date is the known unavailableours as discussed in Section 5.1. The estimated unavailable time is one-half the time between the last time the

omponent is known to be available and the failure discovery date. An exception to this calculation of the esti-

ated unavailable time is made for cases in which the estimated unavailable time period is prior to the June 29,1989 start date, In those cases, the estimated unavailable time is taken from the start date to the failure date.

e calculated known and estimated unavailable days are shown with the input data in Table 1. Once theown and estimated unavailable days are determined for each component, they are entered into a spreadsheet

hich: (1) totals the known and estimated unavailable days for each component; and, (2) calculates the compoent average unavailability indicator by dividing this total by the total time period for the component (366

ays). The spreadsheet also sums the unavailable days and the total time periods for all the components in a

nit, and then calculates a unit average. This process is repeated for all three units. A Holophane overall plantnit average is calculated. The spreadsheet calculations were manually verified. The spreadsheet is duplicated
