Docket No. 50-346 Serial No. 08-88-019 i Mr. Donald C. Shelton Vice President - Nuclear Toledo Edison Company Edison Plaza - Stop 712 300 Madison Avenue Toledo, Ohio 43652

Dear Mr. Shelton:

SUBJECT:

TRANSMITTAL OF PERFORMANCE INDICATOR DATA The NRC Office for Analysis and Evaluation of Operational Data (AE00) issues on a quarterly basis, a report entitled "Performance Indicators for Operating Comercial Nuclear Power Reactors." The latest report dated February 1988, was issued in two parts; the first part contains plots of the more important perfomance indicators for each operating plant for the eight quarters ending on December 31, 1987. The second part provides tables containing detailed data as well as a description of the report contents. In accordance with the policy guidance provided in SECY-87-207, a copy of this report has recently been placed in the Public Document Room (PDR).

We are providing for your information, a two-page set of graphs pertaining to Davis-Besse which was extracted from this report (Attachment 1). The first page is a plot of the six performance indicators initially approved for implementa-tion in the NRC's performance indicator program. These are: automatic scrams while critical; safety system actuations; significant events; safety system failures; forced outage rates; and equipment forced outages per 1000 critical hours.

The second page is a statistical plot of the trends of these six performance indicators for each unit against itself (i.e., deviations of the last two quarters from the means of the previous four quarters). Deviations of the six plant specific perfomance indicators from the industry average for older plants are also presented on this page.

In reviewing this data, it is important that you recognize that the perfomance indicators are intended only for use as one of several tools which the NRC utilizes to monitor trends in performance for each plant. The SALP program, for example, is another independent approach for determining licensee and plant perfomance. Our approach to these performance indicators is that they can be used as assessment tools to identify poor performance, but only when the underlying causes of this poor performance are carefully assessed, evaluated and understood. Without this understanding, use of performance indicators can lead to a misinterpretation of the data.

j To assist you in understanding our use of these indicators, Attachment 2 l contains a set of definitions for the six indicators cited above, plus the 1 definition of a seventh indicator, the collective radiation exposure. This I attachment also provides some additional guidance in the form of precautions and explanations.

Attachment 3 contains a seven-year history of the collective radiation exposure for your plant (Table 11.1) and a three-year moving average of this same data (Table 11.2). In Attachment 4, the latest SALP data for your plant is contained in Table 11.3 as well as two four-quarter averages of the basic six performance indicators. Finally, Attachment 5 contains the numerical values by quarter for the six performance indicators plotted in Attachment 1 (Tables 11.4, 11.7, 11.8, 11.9, 11.10 and 11.11). Table 11.12 contains the unit critical hours for each of the eight quarters considered in this report.

You should note that the notation "PREDECISIONAL" has been crossed out on each page of the report. With placement of this report in the PDR and issuance of the pertinent pages to the holders of operating licenses, this designation is no longer applicable.

If you have any questions on this matter, please contact me promptly at (301)492-3063.

Sincerely,

/s /

5. PETAILED DEFINITIONS OF INDICATORS The definitions of the seven indicators currently in the program are provided below.

5.1 Automatic Scrams while Critical (SCRAMS)

(IA) Total Scrams Total scrams are the number of unplanned automatic scrams while critical.

This indicator is the same as the corresponding thPO indicator. Examples of the types of scrams counted are those that result from unplanned transients, eouipment failures, spurious signals, or human error. Also included in the total scrams are those that occur during the execution of procedures in which there is a high chance of a scram occurring, but the occurrence of the~ scram is not planned. Scran data are primarily derived from LER infomation and supple-mented as necessary from 50.72 reports. The reactor is critical if so stated in the reports. Otherwise it is determined from the review of the information.

(IP) Scrams Above 15 Percent Power per 1000 Critical Hours 1 This subset of total scrams includes t'he automatic scrams occurring above 15 percent reactor power per 1000 hours0.0116 days <br />0.278 hours <br />0.00165 weeks <br />3.805e-4 months <br /> of critical operation.

I (IC) Scrams at or Below 15 Percent Power This subset of total scrams includes the automatic scrams occurring while the reactor is at or below 15 percent power.

5.2 Safety System Actuations (SSA)

Safety system actuations are actuations of the emergency core cooling system (ECCS) (actual or spurious) and the emer response to low voltage on a safety bus)gency. This indicator ac power systems is the same as the (actual, in corresponding INPO indicator. Input for this indicator is derived from LERs and supplemented by 50.72 reports.

In determining what items should be included in the data for this indicator, the following conventions are used:

  • Only actuations of the high pressure injection system, low pressure l l

injection system or safety injection tanks are counted for PWRs. For BWRs, only actuations of the high pressure coolant injection system, the low pressure coolant injection tystem, the high pressure core spray system, or the low pressure core spray system art counted. No actuations of the reactor core isolation cooling system are counted, j Actuations of emergency ac power system due to loss of power to a safe, guards bus are captured primarily based on indications of low voltage signals in the emergency power system.

Actuations of any of the ecuipment associated with the specific ECCS or emergency ac power system are considered necessary and sufficient to These data are available as supplemental indicator data in Tables 11.3 and 11.4.

M:::::::^N".

. Attachment 2 constitute a data count. For example, if only a valve in a system is comanded to move to its emergency operational position, this is counted as en actuation. A pump does not have to be comanded to go to its emer-gency mode of operation, or fluid does not need to be injected for an occurrence to be counted.

  • Only one ECCS actuation is counted in any one occurrence, even if multiple ECCSs actuate during the occurrence. For example, actuation of both the high pressure injection and the low pressure injection systems at a PWR during the same oc:urrence counts as only a single ECCS actuation for that occurrence.

Only one EDG actuation is counted in any one occurrence, even if multiple EDGs actuate during the occurrence. For example, actuation of all four EDGs at a unit counts as only a single EDG actuation for that occurrence.

  • Occurrences involving actuations of both an EDG on a dead bus and an ECCS are given a count of two, one for the EDG actuation and one for the ECCS actuation.
  • At multi-unit sites that share eouipment (e.g., swing EOG or shared buses), actuations are counted and assigned to only one unit, even if multiple units are involved. This count,is assigned to the unit where the actuatier, signal or loss of power originated. If the signal source cannot be determined to be associated with one unit, the actuatinn is assigned to the unit with the lowest unit number unless the licensee has specifically assigned the reported occurrence to a higher number unit.

5.3 Sionificant Events (SE)

Significant events are those ey?nts identified by the detailed screening and evaluation of operating experience by the NRC staff. The screening process includes the daily review and discussion of all repcrted operating reactor events and operational data such as special tests being conducted or construc-tion activity.

An event identified from the screening as a candidate significant event is further evaluated to determine if there is an actual or potential threat to the health and safety of the public involved. Specific examples of the types of criteria are sumarized as follows.

(1) Deg radation af important safety equipment. Events that will be considered uncer this classification include situations where either there existed the potential for or there was an actual reduction in the operational capability of equipment. For example, identification of a comen cause failure rechanism which could cause failure of redundant components or multiple independent component failures in response to a test or actual demand signal. This category would not include such items as a missed surveillance test where the equipment was subsequently tested and deter-mined to be operable.

Attachment 2

":0:0::'0!"'.

(2) Unexpected plant response to a transient or a maior transient. Events that will be considereo under this classification include situations where changes in reactor parameters represent unanticipated reductions in margins of safety. For example, a rapid plant cooldown following a reactor trip exacerbated by a balance of plant malfunction or an undesirable systems interaction. This category would not include minor differences in predicted and observed conditions that can be reasonably explained by instrument errors or modeling techniques and simplifying assumptions.

(3) Degradation of fuel integrit> > primary coolant pressure boundary, or important associateo structures. Events considered under this category would include those of similar character to those identified in item 1, above, related to the fuel, RCS, containment, or important plant structures.

(4) Scram with complication. A "scram with complication" is an RDS actuation, when critical, followed by an eouipment failure or malfunction or personnel e rror. The failure, malfunction, or error is generally not to include those that cause the transient which leads to the RPS actuation, or those that directly cause the scram. Failures that both cause the scram and raduce the capability of the mitigating system (e.g., electric power, instrument air, other auxiliary support functions, or deficient procedures) will be counted.

Examples of eouipment failure / malfunctions include:

a. Mitigatina system failures - loss of redundancy due to single fail-ure, reduced capacity or margin. This includes components or trains out of service for maintenance,
b. Failure adding to complexity of event - erroneous control system hsponses, electrical switching difficulties, mitigating system and key plant parameter instrumentation malfunctions / failures.
c. Additional avent initiators - stuck open primary or secondary relief /

safety valves, pipe breaks, and operating wrong equipment / trains.

Examples of personal errors include personnel:

a. Improper control or termination of mitigating system,
b. Misdiagnosis ef the event or failure to follow procedures.

In addition to the situations described in items 1-4, above, other broad categories considered for significant events are as follows:

(5) Unplanned release of radioactivity. Events considered under this category include an unplanned release of radioactivity that had the potential for or actually exceeded the limits of the Technical Specifications or the Pegulations.

4 Attachment 2 II,:0::::: ~ '.

4 (6) Operation outside the limits of the Technical Specifications. Events that will be considered unoer this classification incluoe situations where plant operation was conducted inconsistent with the license requirements.

This category would apply to risk significant deviations and mesi likely not incluoe an incident involving a missed surveillance, small errors in setpoints, or other administratively inoperable conditions.

(7) Other. For example, a series of events or recurring incidents that when considered collectively represent ineffective corrective actions, or a deficiency in the olant hardware or administrative programs.

5.4 Safety System Fail ~ures (SSF)

Safety system failures are any events or conditions that, by themselves, could prevent fulfillment of the safety function for structures or systems. Where a system consists of multiple redundant subsystem or trains, failure of all trains constitutes a safety system failure. Failure of one of two or more trains is not counted as a safety system failure. The oefinition for the indi-cator parallels NRC reporting recuirements in 10 CFR 50.72 and 10 CFR 50.73.

The following list gives the major systems and subsystems which are monitored for this indicator:

Attachment 2 i "0000:0 *'".

l 5.5 Forced Outage Rate (FOR) l Forced outages are those required by the end of the weekend following the l discovery of an off-normal condition. The forced outage rate is the number of fcreed outage hours divided by the sum of unit service hours (i.e., generator online hours) and forced outage hours. This indicator is the same as that of INPO and the NPC monthly operating report. The data are generalty obtained from the monthly operating reports. In some cases when the reports are not available, the data are obtained directly from the licensees.

5.6 Equipment Forced Outaces per 1000 Critical Hours (EFO)

This is the number of forced outages caused by eouipment failures per 1000 critical hours. It is the inverse of the mean time between forced outages caused by equipment failures. The inverse number was adopted to facilitate calculation and display. The source of this data is the same as that for the forced outage rate.

5.7 Collective Radiation Exposeye.

This is the total radiation dose at the site for a given period. The site total is divided by the number of units at the site contributing to the radia-tion exposure to obtain unit values. This indicator is the same as that of INPO.

6. PRECAUTIONS The data for this report were obtained from relfable NRC sources as discussed earlier and were reviewed by NRC personnel in headquarters and the regions for completeness and accuracy. The data for the fourth quarter of 1987 will be reviewed again in preparation for the next quarterly report in order to ensure that late information, if any, is accounted for.

Although certain NRC perfonnance indicators are the same as those of INPO l overall performance indicators, the criteria for including the data in the l calculations for industry average are not the same in all cases. For example, '

INPO does not include scram values for a plant with cumulative capacity factor of less than 25 percent during the time period being considered in calculating the industry average. The NRC does not exclude such plants. Therefore, the industry average values of the coemen indicators are likely to be different.

Tables 10.1 to 10.109 provide listings of each plant's Automatic Scrars Fhile Critical, Safety System Actuations, Significant Events and Safety System Failures for the third and fourth quarters of 1987. Beginning with this report, event descriptions in the listings cre being provided for both the current and previous quarters.

For scrams above 15 percent power per 1000 critical hours, the results for plants with less than 1000 critical hours in a quarter can be distorted. For this report the degree of distortion has been reduced by using at least a minimum value of 200 critical hours in the calculations for any given quarter.

)

The results for equipment forced outages per 1000 critical hours can be distor-ted in a similar manner. This distortion has also been reduced by using at least 200 critical hours in the calculations.

I Forced outage rates that are based on licensee monthly operating reports do not I always appear consistent for plants undergoing long shutdown periods, l There are two additional categories of information that are included in the program for collection, monitoring, and future development, but are not inclu- '

l ded in this report. They are causes associated with scrams, safety system actuations, significant .tvents, and safety system failures such as personnel Grror, maintenance problems, eouipment failures and design / fabrication /

construction error; and the number of forced outages.

in addition, the staff is developing indicators in several areas. The highest priority areas for development are maintenance and training. Other important areas include limitino conditions for operations (LCO) action state-ments, number of items out of service and causes of events as well as risk-based and programmatic indicators.

7. ANNUAL COLLECTIVE RADIATION EXPOSURE DATA Because the collective radiation exposure data are currently available only on an annual basis, the information displayed is for the annual data through 1986. Table 11.1 provides the annual cuwlative doses in person-rem for 1980 through 1986. Table 11.2 provides the 3-y0ar moving averages of the data in Table 11.1 for the 3-year periods ending with 1982, 1983, 1984, 1985, and 1986.

Data on a quarterly basis are in the process of being obtained.

8. COMPUTATIONAL NOTES

' l

_ The following computatiora. notes describe some of the detailed methods used in l calculations and displays for this report. In future reports, the details may change as improved techniques are obtained.

8.1 The report addresses plants licensed for operation in the fourth cuarter l of 1987 or earlier. The data extend through the fourth quarter of 1987.

8.2 Blanks are used under the following conditions for newer plants:

(1) For all indicators until an operating license is first received, (2) For scrams until critical hours are first reported, or (3) For forcec etages until power generation is first reported; thereaf ter, numerical values are used. For example, plants shut down for an entire quarter after initial criticality have zeroes for scrams rather than blanks.

8.3 Blanks are not used in calculating averages and standard deviations.

Zeroes do count in such calculations.

.7-8.4 For the plant sumaries (Figures 4.1 - 4.109 of Part !),

(1) The top chart, "Trends," is baseo en the following numbers:

(a) The plant's moving average for the latest two quarters, {

(b) The plant's moving averace for the four quarters previous to thelatesttwocuarters(iftk ' are not at least two quarters i of data for this moving averim no value is displayed on the I chart),and (c) A standard deviation based on the plant's previous four quarters of data (if the standard deviation is zero, an average of values for older or newer plants, as appropriate, is used);

(2) The bottom chart, "Deviations from Older Plant Means" or "Deviations from Newer Plant Means," uses the following numbers:

(a) Moving average of the plant's latest four cuarters (if there are not at least two quarters for this, no value is displayed on the chart). -

(b) Average of the latest four-quarter moving averages for older plants or newer plants (outliers more than 2.5 standard deviations from the mean on the first calculation were discarded and the mean and standard deviation were recomputed), and (c) Standard deviation based on the latest four-quarter moving averages for older or newer plants (outliers were discarded as discussedabove);and (3) Moving averages (average of four cuarterly values) are used throughout rather than calculating true means (e.g., annual averages) for ratios such as equipment forced outages par 1000 critical hours.

8.5 The following parameters were used for detailed plant analysis charts of each plant's quarterly data (Figures 4.1 through 4.109 of Part I).

(1) Older plant averages are the averages of older plant values calculated quarter by quarter.

(2) Newer plant averages are single numbers that span all quarters, the average of all new plant values in the data set.

8.6 For certain plants in long-tem shutdown, such as Browns Ferry, Sequoyah, Pilgrim and Pancho Seco, Scram Forced Outage Rate, and Eouipment Forced Outages bars were suppressed in the plant summary charts.
