The STARS change process begins after the need is identified and approved.2.3 The STARS change process utilizes a graded approach to configuration management established in the EPRI Guidelines for Optimizing the Engineering Change Process for Nuclear Power Plants. The level of rigor given to a MODIFICATION for a structure, system, or component (SSC) is commensurate with the safety significance and complexity of the design.2.4 The STARS process categorizes changes utilizing an assessment matrix. The categories of change are described below.2.4.1 DESIGN CHANGEs are the highest level of ENGINEERING CHANGE and require the most extensive and formalized documentation.

The change is a DESIGN CHANGE if, for example.it: a. Adds or removes an ENGINEERING CONTROLLED SSC b. Adds or changes a function or failure mode of an existing ENGINEERING CONTROLLED SSC c. Alters the bounding parameters used to define the established DESIGN BASIS of the plant.2.4.2 A CONFIGURATION CHANGE results in changing the configuration, either the hardware or the documentation, of an ITEM which meets the functions of both the ITEM and applicable interfaces, and does not introduce new failure modes. CONFIGURATION CHANGES include REPLACEMENT ITEM EVALUATIONS.

2.4.3 ADMINISTRATIVE

CHANGE. If the change is categorized as administrative, it is processed with minimal review and no HAZARDS SCREENING or PROGRAMS SCREENING is required.2.4.4 COMMERCIAL CHANGE. If the change has been categorized as a COMMERCIAL CHANGE, by Change Assessment Matrix screening or inclusion in the sites Commercial Control Exemption List, the 2 of 11 STARS -ENG -5000, revision 001 STARS ENGINEERING CONFIGURATION MANAGEMENT PROGRAM change is processed using the STARS Commercial Change procedure.

Nuclear Plant Engineering is not required for specifying equipment and performing analysis prior to making the change. However, Engineering is available, upon request, to provide input as needed.Known nuclear HAZARDS and plant impacts have been considered and determined to not apply when the SSC was categorized as"Commercial", however, some HAZARDS such as fire protection, control room habitability, and flood HAZARD still need to be considered.

2.4.5 ENGINEERING

EVALUATION.

This is a form of communication between Engineering and other departments that clarifies existing design and licensing information.

It does not require a new Engineering analysis to form the basis for the information nor does it require the generation or modification of design output documents.

This information communicated remains consistent with all existing licensing and design information.

Evaluations may, for example: a Interpret, clarify or communicate existing design requirements.'

b Identify REWORK dispositions.

2.5 The change is then processed in accordance with the category selected in the matrix.2.6 Where required, the PROGRAMS review and HAZARDS review extends the gradation process by identifying areas requiring in depth evaluations such as fire protection or seismic 1111 issues.3 DEFINITIONS

3.1 Basis

3.1.1 Licensing

Basis The set of NRC requirements applicable to the plant, and the licensee's written commitments for assuring compliance with and operation within applicable NRC requirements and the plant specific design basis (including all modifications and additions to such regulations, orders, license conditions, exemptions, and technical specifications).

It also includes the plant specific design basis information defined in I OCFR5O0.2 as documented in the most recent SAR as required by I OCFR71 and the licensee's commitments remaining in effect that were made in docketed licensing correspondence such as licensee responses to NRC bulletins, generic letters, and enforcement actions, as well as licensee comnmitments documented in NRC safety evaluations or licensee event reports (Taken with some minor editorial modification from the definition of Current Licensing Basis in GL 91 -18, rev 1).3 of 11 STARS -ENG -5000, revision 001 STARS ENGINEERING CONFIGURATION MANAGEMENT PROGRAM 3.1.2 Design Bases (Design Basis)Design bases means that infonrmation which identifies the specific functions to be performed by a structure, system, or component of a facility and the specific values or ranges of values chosen for controlling parameters as reference bounds for design.These values may be (1) restraints derived from generally accepted"state-of-the-art" practices for achieving functional goals or (2)requirements derived from analysis (based on calculations and/or experiments) of the effects of a postulated accident for which a structure, system, or component must meet its fuinctional goals. (From I1OCFR 5 0.2).3.1.3 Design Function The operation an item is required to perform to meet the component or system design basis. [EPRI NP-6406]3.1.4 Engineering Design Bases (Engineering Design Basis)The entire set of design constraints that are implemented, including those that are (1) part of the current licensing bases and form the bases for the [regulator]

staff s safety judgments and (2) those that. are not included in the current licensing bases but are implemented to achieve certain economies of operation, maintenance, procurement, installation, or construction. (As defined in NUYREG-1397).

3.1.5 Technical

Requirements These parameters define the function or performance of a given SSC in a particular application/end-use or group of applications/end-uses.

3.2 Change

3.2.1 Administrative

Change An inconsequential revision to a controlled engineering document that does not affect the design, functions or method of performing the function of a structure, system or component (SSC).3.2.2 At-Risk Field Change Notice The process of implementing a Field Change Notice (FCN) in the field while the corresponding engineering disposition is being prepared and reviewed.

At-Risk FCN use is limited. There is a risk that the work performed may not agree with the approved disposition.

At-Risk FCNs are subject to the following conditions:

a The affected SSCs must remain out-of-service and not be declared operable until the At-Risk FCN is reviewed and approved b At-Risk FCNs are limited to the scope of the original Modification Package 4 of 11 I I IM 22 Ei STARS -ENG -5000, revision 001 STARS ENGINEERING CONFIGURATION MANAGEMENT PROGRAM 3.2.3 Commercial Change A change to SSCs that have been screened out of the Engineering processes by the Design Authority.

Changes are performned in accordance with commercial codes and standards.

Configuration management may be needed.3.2.4 Concurrent Change A Concurrent Change is a hardware change that is being implemented in the field while the corresponding Modification Package is being prepared.

Concurrent Changes are not often performed because there exists an inherent risk that the work performed in the field may not agree with the final approved and released Modification Package.Restrictions apply to the use of a Concurrent Change.3.2.5 Configuration Change A change in configuration that can be either physical or in documentation/analysis that preserves the functions and does not introduce new failure modes. This includes a change to the configuration of a replacement item which is not a like-for-like replacement of the present design.3.2.6 Design Change A change where a fuinction is changed or a new failure mode is introduced.

3.2.7 Engineering

Change Any change to the design or configuration of an Engineering Controlled SSC.3.2.8 Field Change Notice The process of identifying and resolving, including review and approval as needed, changes to the engineering change package made after its release for implementation.

Field work associated with a FCN must stop and be put in a safe condition until the FCN is appoved.3.2.9 Hardware Change A physical change to SSCs, including instrument seipoint changes and electronic software changes.3.2.10 Modification A change to the configuration of a SSC. It is a change to the physical plant and/or the documentation associated with it. The term encompasses all categories of change.3.3 Design Input 5 of I I I ii E 102~ 0 STARS -ENG -5000, revision 001 STARS ENGINEERING CONFIGURATION MANAGEMENT PROGRAM Those criteria, parameters, bases or other design requirements upon which detailed final design is based (from ANSI N45.2.1 1-1974).3.4 Design Verification The process of reviewing, confirming or substantiating the design by one or more methods to provide assurance that the design meets the specified design inputs. Independent verification is performed by any competent individuals or groups other than those who performed the original design but who may be from the same organization. (from ANSI N45.2.1 1).3.5 Documents 3.5.1 Affected Document A document which requires revision to reflect the modification but is not required to implement the modification.

Affected documents are revised prior to change package closure and can be approved and issued following implementation of the Modification Package.3.5.2 Controlled Document A document, whose release, distribution and maintenance are verified, recorded and authorized by an assigned organization.

3.5.3 Design

Document A controlled document that specifies technical and/or quality requirements for the design, fabrication, installation, test, or operation of a structure, system, or component and that is verified as required by 10 CFR5O0 Appendix B, Criterion 111.3.5.4 Modification Document An interim or as-built change to an existing or new document that is included in and released with a change package. Modification documents are utilized when required to implement or support the implementation of a change package and/or to update engineering documents to reflect as-built conditions 3.5.5 Work Document A generic term used to identify the forms and associated documents used by site-specific work control organizations.

3.6 Engineering

Evaluation This is a form of communication between Engineering and other departments that clarifies existing design and licensing informnation.

It does not require a new Engineering analysis to form the basis for the information nor does it require the generation or modification of design output documents.

This information communicated remains consistent with all existing licensing and design information.

3.7 Margin

6 of 11 STARS -ENG -5000, revision 001 STARS ENGINEERING CONFIGURATION MANAGEMENT PROGRAM 3.7.1 Design Margin The range of plant operation above the operating limit and below the analyzed design limit. Design Margin is controlled by Engineering.

LO, LO-LO, HI and HI-HI alarms fall within the Operating Margin.3.8 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 requirements

[ANSI N45.2.10-1973].

3.9 Rework

The process by which a nonconforming item is made to conform to a prior specified requirement by completion, re-machining, reassembling or other corrective means [ANSI N45.2.10-1973].

3. 10 Replacement Item Equivalency (RIE)A technical evaluation performed to confirm that an alternate replacement item (not like-for-like to the original) will satisfactorily perform its (engineeri

'ng)design function.

This term is synonymous with an "equal-to-or-better-than" evaluation.

[ANSI N45.2.10-1973]

3.10.2 Replacement Item An item which replaces an original or installed item (either like-for-like or alternate) for which an equivalency evaluation is performed to assure that interfaces, interchangeability, safety, fit and function are not adversely affected or contrary to regulatory requirements.

3.10.3 Alternate Replacement A replacement item not identical to the original.

These replacement items require an equivalency evaluation to assure that the design function will be maintained.

[EPRI NP-64061 3.10.4 Critical Characteristics for Design 7 of 11 STARS -ENG -5000, revision 001 STARS ENGINEERING CONFIGURATION MANAGEMENT PROGRAM Those properties or attributes which are essential for the item's form, fit and functional performance.
