of the Equipment History Program.
1.2 nis procedure provides instmetions for writing reports to be entered into the ,
Equipment History Datahame i i
1.3 This procedure establishes administrative osamoIs for' tending and~ tracking l N (including failures) involving plant structures, systems, and components for the purpose ofidentifying and correcting repetitive detradation and failures. (IR 93-005)(DR 587-098) 1.4 This process applies to plant structures, systems, and components (SSC) which

't. ..
When the prEncipal components needed to perform a system's function are arranged in paralle! (such as multiple high pressurizer pressure instrument loops), ;
each is considered a separate channel.
{
i 2.2 COGNIZANT ENGINEER: The engineer designated by the Plant Engineering l
Department (PED) Manager or Design Engineering Department (DED) Manager as responsible for overall coordinaticn of design or plant change implementation and Section XI Work Package review. i 2.3 CORRECTIVE MAINTENANCE: nose activities performed to rework, repair !
or replace equipment or components that have failed. ;
.c :
2.4 DEFICIENCY
A deficiency is any condition where a component, system or l structure does not meet its design criteria or cannot perform its intended function.
l The result of a deficiency identification may be: Rework, Replacement, Repair, ;
Use As-Is, or Modification. The determination of Repair, Use-As-Is, l Replacement Equivalent Change or Modification is made by Engineering via a -
Plant Change Form (PCF).

Page 4 of 27 2.13 REPAIR: The process of restoring a nonconforming characteristic to a condition such that the capability of an item to function reliably and safely is unimpaired, ,
even though' that item still may not conform to the original design requirement.
2.14 REPLACEMENT: The installation of spare or renewal parts, components, :
accessories or subassemblies of a component or system or system changes. !
i 2.15 REWORK: The process by which a nonconforming item is made to conform to

2.16 SERVICE REQUEST (SR): Form used to document and evaluate the need for a Maintenance work activity and to request general manpower support services.
2.17 TRAIN: One of two or more functional paths in a mechanical or electrical system (i.e., a functional path is a gmup of components, or a single component, -
that is fully capable of independently performing one of the system's functions.
2.18 TREND: A line of general movement in the course of time of a statistically I detectable change.
2.19 TREND ADVERSE TO QUALITY: Any series of conditions that, due to their recurrent nature, may collectively be symptomatic of a condition adverse to ;
quality. ;
i 2.20 USE-AS-IS: A disposition which may be imposed for a nonconforming j condition when it can be established that the discrepancy will result in no {
adverse conditions and that the item under consideration will continue to meet all !
engineering functional requirements including performance, maintainability, fit {
and safety. l 2.21 WORK MANAGEMENT SYSTEM (WMS): Computerized system used to 7
retain information pertinent to work document activities, including description, ;
priority and status. l 2.22 WORK ORDER (WO): Form used to document Work Instructions in a Work l Package and to p. ovide approval and completion signoffs for the Work Package. l i
2.23 WORK PACKAGE: A package containing a Service Request or Preventive i Maintenance Work Order or Modification Work Order and other information :
required to perform the work (e.g., drawings, technical manuals, etc.).

Rev.0 Page 6 of 27 4.0 Program Descriotion 4.1 General ,
4.1.1 The Equipment History Program consists of three areas of responsibility:
4.1.1.1 Nuclear Plant Reliability Data System (NPRDS) Program, 4.1.1.2 Equipment History reporting, and 4.1.1.3 Failure Data Trending.
l-4.1.2 The NPRDS Program is described in OPGP03-ZA-0038, Nuclear Plant Reliability Data System Program.
4.1.3 Equipment History reporting shall be performed in accordance with Section 4.2. The database contains maintenance and failure data on equipment which meet the guidelines of Addendum 1. This data may be used in the following applications:
4.1.3.1 Failure Data Trending 4.1.3.2 Reliability Centered Maintenance 4.1.3.3 Preventive Maintenance Optimization 4.1.3.4 Maintenance Rule Implementation 4.1.3.5 Probabilistic Risk Assessment 4.1.4 Equipment History Reports shall be derived from Service Requests (SR) 5 and Preventive Maintenance Packages (PM) but may contain applicable :
information from License Event Reports, Station Problem Reports, Surveillances, and other documents which may contain equipment maintenance or failure data.
