ANALYSIS OF THE PERFORMANCE INDICATOR DATA THROUGH DECEMBER 1988 The results of a generic analysis of the data contained in the this issue of the quarterly Performance Indicator (PI) report are summarized below. The analysis is consistent with Commission direction contained in staff require-mentsmemorandumofgune 24, 1988 (SECY-88-103), Status of Performance Indicator Program. - The analysis is in the form of an industry-wide summary of performance indicators.
The attached figure 1 shows an annual industry average value for each of the seven Pls and the unit availability factor. The unit availability factor is calculated from data provided in NUREG-0020. In plants in extended shutdowns have been excluded. g iculating Also, the 1988the averages, the averages for collective radiation exposure are not shown as the data are not ,
available.
The figures show an improving industry performance trend from 1987 to 1988 for five of the seven PIs. For the PI, Significant Events, there was essentially no change from 1987. For the PI, Collective Radiation Exposure the data are j not available for 1988. The unit availability factor which is one measure of plant operational reliability factor which is one measure of plant operational reliability is also showing improvement and a likeness with the performance indicator trends.

NUCLEAR REGULATORY COMMISSION ANNOUNCEMENT NO. 30 OATE: February 5, 1988 To ALL NRC EMPLOYEE 5
SUBJECT:
Gul0ANCE ON THE USE OF PERFORMANCE INDICATORS The Comission has approved the internal guidance for the use of perfnmance indicators for operating power plants. All NRC employees shall adhere to the following guidance.
The perfonnance indicator program provides an additional view of operational performance and enhances our ability to recognize areas of poor and/or declining safety performance of operating plants. However, it is only a tool and is to be used in conjunction with other tools such as the results of routine and special inspections and SALP for providing input to NRC management decisions regarding the need to adjust plant-specific regulatory programs.
't should be recognized that performance indicators have limitations and are subject to misinterpretation. Therefore, caution is warranted in the.
interpretation and use of the data. The application of perfomance indicators for purposes and in manners other than thosa stated above will l be counter to the NRC objective of ensuring operational safety. To avoid '
such situations, the following specific directives are provided:
- 1. The performance indicator program for operating reactors is a single, coordinated, overall NRC program under the direction of AE00. NRC l offices other than AE00 should not deviate from the NRC program without written pennission of the E00 or the Director, AE00.
- 2. Performance indicators are intended as a tool for senior NRC management to monitor trends in overall perfonnance for a given plant. The performance indicators for a given plant should be viewed as a set. When viewed as' a set, the performance indicators provide an additiont.1 measure of plant operational performance.
O viii
O 3. performance 4neicators ,, intended to be ces o< severai toois for !
use by senior NRC management in decision making regarding plant i specific regulatory programs. Senior management in each NRC office '
should have access to performance indicators for their assigned unit (s). However, no regulatory action should be taken on the basis i of performance indicator program results alone.
l
- 4. Performance indicators should not be used for ranking nuclear power
, plants or presented in such a way as to imply " problem facility" l status for individual plants. l
- 5. The performance indicator program is separate and distinct from the Systematic Assessment of Licensee Performance (SALP) Progras. Although the indicators have relationships in varying degrees to SALP functional areas, the indicators themselves should not be a factor in judgements about the effectiveness or rating in a particular SALP functional area.
In particular, it would be inappropriate to make reference to performance indicator program results in arriving at a SALP rating.
- 6. NRC senior management should bear in sind when evaluating performance ,
indicator results that the indicators are assessment tools that aid in identification of unanticipated performance, and that the underlying causes should be carefully assessed, evaluated, and understood (factoring in other available information).
- 7. Quarterly compilations of performance indicator program results should be placed in the Public Occument Room following dissemination to NRC management and the Commission.
It should be recognized that in conducting reviews, inspections and evaluations of plants it is often necessary to rely on plant data. Such information has been routinely used in our SALP, SER anc Techni' cal Evaluation reports. The forgoing policy is not intended to change this process. l ctorkejl Jr.

- 1. INTRODUCTION This Nuclear Regulatory Commission (NRC/ Commission) report presents performance indicator data through December 1988 for 110 operating reactors. There are seven indicators in the NRC Performance Indicator Program for Operating Commercial Nuclear Power Plants: (1) automatic scrams while critical, (2 safety system actuations, (3) significant events, (4) safety system failures, (5 forced outage rate, (6) equipment forced outages /1000 critical hours, and (7 collective radiation exposure. 1 The performance indicator data are extracted from licensee event reports submitted in accordance with 10 CFR 50.73, immediate notifications to the NRC operations center in accordance with 10 CFR 50.72, monthly operating reports in accordance with plant technical specifications, and radiation exposure reports in accordance with 10 CFR 20.407. Quarterly data for all indicators except collective radiation exposure are presented in the form of charts and tables for each plant. The exposure data are presented on an annual basis. The charts for each plant are provided in Part I of the report, and the tables in Part II.
An analysis of the performance indicator data through December,1988 and the guidance on the use of performance indicators are provided in the preceding pages.
l
- 2. BACKGROUND i i
Since may 1986, an interoffice task group has been working to develop an over- l all NRC program for using quantitative indicators of nuclear power plant safety performance. In July and August of 1986, the group conducted a trial program for 50 plants with 17 prospective performance indicators. For the most part, i this trial program used data through calendar year 1984. The group then selected eight performance indicators to be recommended as the best set for initial implementation. One of these, corrective maintenance backlog, was deleted by the staff following consideration of industry comments.
In October 1986, a prototype report was prepared by expanding the trial program data to 100 operating reactors and including the data through the first half of 1986. The staff's recommended program, the task group report, and the proto-type report were documented in SECY 86-317, Performance Indicators, dated October 28, 1986. The Commission was briefed on the staff's recommended program in November 1986, and approved the implementation of the program in December 1986, instructing the staff to delete the enforcement action
. index from the set of indicators.
I Since February 1987, the performance indicator reports are being provided to the senior management on a quarterly basis. The February 1989 issue of the quarterly report contains data through December 1988. I O

- 3. DEFINITIONS OF INDICATORS 3.1 Automatic Scrams While Critical (Scrams):
This is identical to.the indicator, unplanned automatic scrams while critical, used by the Institute of Nuclear Power. Operations (INPO). In addition, the number of automatic scrams from above 15% power per 1000 critical hours and the number of automatic scrams while critical below 15% power are monitored.
3.2 Safety System Actuations (SSA): :
This is identical to the indicator, unplanned safety system actuations, used by INP0 and includes actual and inadvertent actuations of Emergency Core Cooling Systems (ECCS), as well as actuations of emergency ac power j systems due to loss of power to a vital bus. !
3.3 Significant Events (SE):
These events are identified by the detailed screening of operating experience by the Office of Nuclear Reactor Regulation (NRR) and the Office for Analysis and Evaluation of Operational Data (AE00), and ,
include degradation of important safety equipment, unexpected plant R response to a transient, a major transient, discovery .of a major 1 condition not considered in the plant safety analysis, and degradation l of fuel integrity, primary coolant pressure boundary, or important i associated structures.
3.4 Safety System Failures (SSF):
)
This indicator includes any event or condition that alone could prevent the fulfillment of the safety function of structures or systems. Twenty-four systems or subsystems are monitored for this indicator.
3.5 Forced Outage Rate (FOR):
This indicator's definition is identical to the one use by INP0 and the l NRC Grey Book (NUREG-0020). It is the number of forced outage. hours divided by the sum of forced outage hours and generator on-line hours.
This indicator is used only for plants that are in commercial operation.
3.6 Equipment Forced Outages Per 1000 Critical Hours (EF0):
This is the inverse of the mean time between forced outages caused by .
equipment failures. The mean time is equal to the number of hours the i reactor is critical in a period divided by the number of forced outages caused by equipment failures in that period.' This indicator is used only for plants that are in commercial operation.
g 3.7 Collective Radiation Exposure:
This indicator is identical to the one used by INP0, It is the total' dose at the station. The station total is divided by the number of units at the site contributing to exposure to obtain unit values.
\
3.8 Additional Notes - Part II Part II of this report provides one-line descriptions of each performance indicator event for the first, second, third, and fourth quarters of 1988.
The individual plant tables have been deleted. In addition, an overall industry summary table provides the moving average for the most recent two quarters (two-quarter period) and the moving average for the four quarters that precede the two-quarter period (prior four-quarter period) for each performance indicator (except collective radiation exposure) for each plant, as well as the Systematic Assessment of Licensee Performance (SALP) ratings at the end of this report period for operations, maintenance, surveillance, and quality programs.
The data for this report were obtained fru'n NRC sources and were reviewed by NRC personnel in Headquarters and the Regions for completeness and accuracy. Data for the fourth quarter of 1988, along with the other data, will be reviewed again in preparation for the next quarterly report, in order to ensure that late information, if any, is accounted for.
4 DISPLAY OF PERFORMANCE INDICATOR DATA The performance indicator data are presented in this report on charts and tables as discussed in the following paragraphs.
4.1 Quarterly Data' Figures 4.1 through 4.110 provide detailed plant analysis charts of the quarterly data for each indicator for each plant. These charts also include the plant's critical hours to present a picture of the plant's operating history, industry mean values to provide a comparative perfor-mance level, and the four-quarter moving averages to show trends. Bar charts for older plants include the older plant means; charts for newer plants include both the newer plant means and the older plant means.
These plots give detailed visual pictures for indicators at given plants.
4.2 Plant Summaries Figures 4.1 through 4.110 consist of two (or three) bar charts which provide profiles of each plant's performance indicator trends and performance indicator values. The top chart of each figure shows the number of standard deviations by which the moving average for the most recent two-quarter period varies from the plant's own moving average for the prior four-quarter period. The bottom chart of each figure shows the number of standard deviations by which the plant's moving average for the most recent four quarters (current four-quarter period) varies from an industry mean. Older plants are compared to the older plant means. Newer plants are compared to newer plant means. For the purpose of this report, plants that received full-power licenses in g 1986 or earlier are considered older plants. The others are considered newer plants. The figures for newer plants also have a chart display which compares the plants' current four-quarter period moving averages to the older plant means.

4.3 Annual Industry Averages Annual industry averages for each Performance Indicator are being displayed as Bar Charts. Figure 1 shows the' industry averages of the indicators and the unit availability factor calculated from NUREG-0020 for. the years 1985-1988. In calculating the averages, the plants-in extended shutdown modes were excluded.
The methodology for extracting safety system failures was changed in 1987.
Previously, failures were counted only if the licensee identified a failure by checking the appropriate box on the Licensee Event Report (LER).
Beginning in 1987, failures were identified by detailed review of LERs. The solid black bar for safety systems failures in Figure 1 reflects the old methodology, while the cross-hatched bar reflects the differences due to 3 l the new methodology, t l
