[1] As - Built - The state of any document that reflects the actual physically installed configuration. When an associated Engineering Change reaches Modified or Closed status, then the Engineering Change Markup is considered As-Built.

[2] Assumption - the supposition of plant configuration or station procedures that exists but has no documented supporting design basis. There are two types of assumptions:

Those based on reasonableness, generally backed by similar configurations or practices that are backed by design basis or engineering judgment.

Those that have no design basis but can be conveyed as calculation output in the form of a qualifying or conditional statement such as The results of this calculation are valid if the following maintenance acceptance criteria are met. The calculation then becomes the design basis for the assumed configuration or station practice.

[3] Augmented Quality Related - Structures, Systems and Components (SSC) have been designated as requiring additional quality level oversight or as Important to Safety.

This designation is an optional subset of the classification category non-safety related. It may be applied to any item that is subject to non-safety related regulatory requirements or special requirements imposed by the utility. The scope of the classification category is station specific. [QAPM Section A.1.c] [NP QAPD, Part II, Section 2]

[4] Calculation - A design analysis performed in an orderly process using appropriate design inputs and methodology to provide an original result or conclusion.

Calculations are design process implementing documents that ensure the applicable design inputs are correctly translated into design outputs.

A calculation may be utilized, as necessary, to provide support, basis, and/or justification for existing design, proposed design, preliminary design studies, regulatory/licensing basis, etc., and to establish parameters for equipment performance.

NUCLEAR QUALITY RELATED EN-DC-126 REV. 4 MANAGEMENT REFERENCE USE PAGE 5 OF 36 MANUAL Engineering Calculation Process 3.0 cont

[5] Calculation Change - An amendment to an approved calculation made via an Engineering Change Markup. These changes supplement the calculation to reflect installed/implemented configuration changes or approved (but not installed/implemented) configuration changes. A Calculation Change does not represent plant configuration until the associated Engineering Change reaches Modified or Closed status. At this point, the calculation change is considered As-Built. A Calculation Change will be referred to as an Engineering Change Markup throughout this procedure. Calculation changes are not applicable to processing calculations associated with the New Plant organization.

[6] Design - Technical and management processes which commence with the identification of criterion and which lead to and include the issuance of final design documents. [ANSI N45.2.11-1974] [NP NQA-1-1994, Part I, Introduction, Section 4]

[7] Design Basis - Information that 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.

(a) 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 calculation and/or experiments) of the effects of a postulated accident for which a structure, system or component must meet its functional goals (10CFR50.2).

[8] Design Basis Calculation - Calculations that represent design basis information, which is required to construct, test and operate facility systems, structures, components and/or software.

[9] Design Basis Document - The encapsulation or summary of system or topical information that relates to design bases as defined by 10 CFR 50.2 and engineering design bases. These documents serve to delineate the design intent, and either directly incorporates the related design documentation or are a directory to relate design documentation (e.g., Calculations and analyses). (NUREG-1397)

[10] Design Input - Those criteria, parameters, bases or other design requirements upon which detailed final design is based. [ANSI N45.2.11-1974] [NP NQA-1-1994, Part I, Introduction, Section 4].

NUCLEAR QUALITY RELATED EN-DC-126 REV. 4 MANAGEMENT REFERENCE USE PAGE 6 OF 36 MANUAL Engineering Calculation Process 3.0 cont

[11] Design Output - Drawings, specifications and other documents defining technical requirements of structures, systems and components. (ANSI N45.2.11-1974). The design output of calculations not only includes the results of the calculation, but the conditions identified as configuration or plant practice assumptions that support the calculation results.

[12] [NP] Design Output - Drawings, specifications, and other documents used to define technical requirements of structures, systems, components and computer programs.

[NP NQA-1-1994, Part I, Introduction, Section 4].

[13] Design Verification (DV) - 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. (Adapted from ANSI N45.2.11)

[14] Editorial Change - Minor document /database corrections which do not represent a change to the technical content. Examples include: correcting typographical errors, correcting references to figures, sections, documents, etc., revision to improve grammar or clarity, revision to modify nonessential information.

[15] Engineering Change (EC) - Any change to a structure, system or component including design changes, document only changes and equivalent changes.

[16] Engineering Change Markup (EC markup) - A document used to change controlled Engineering documents and tracked by an Engineering Change.

[17] Electronic Data Management System (EDMS) - The primary system used to provide records and current revision information to personnel, including indexing and imaging of Lifetime and Nonpermanent Quality Assurance Records.

[18] Engineering Judgment - Decisions needed to perform evaluations based on the appropriate knowledge and experience of personnel performing the evaluation.

Engineering judgment should be avoided and is typically used in lieu of specific calculational or other engineering methods to support a value, conclusion, etc. The main consideration is whether other similarly experienced engineers would readily reach the same conclusion. The basis for engineering judgment must be documented in the body of the calculation and is generally classified as an assumption.

[19] INDUS Asset Suite (IAS) - The INDUS software product used by the Entergy operating fleet for Work Management, Document Management, Engineering Change, Action Tracking and Supply Chain (includes Material Control, Inventory Control, Contract Management, Accounts Payable, Procurement Engineering and Purchasing).

[20] Native Files - The electronic files (Word, Excel, etc.) the responsible engineer uses during the preparation of the calculation.

[21] Non-Design Basis Calculation - A calculation that does not change the design or the licensing basis of the plant and its associated EC is therefore exempted from entering the Process Applicability Process (EN-LI-100) or from completing the Calculation Reference Sheet and design inputs. Examples of calculations that are not design bases include:

(1) Sensitivity analyses, (2) Calculations for beyond design basis events, (3) What-if calculations, (4) Trending calculations, (5) Computations to determine conformance to surveillance procedure requirements, (6) Calculations to support the determination of SSC functionality or operability, etc.

(7) Calculations to support a temporary maintenance condition

[22] Pending - The state of any document for which a physical change to the plant is required by its approved associated Engineering Change and not yet implemented.

An Engineering Change Markup is considered Pending when the document is listed on its associated Engineering Change Affected Document List. When the Engineering Change reaches Modified or Closed status, the Engineering Change Markup is considered As-Built.

[23] [NP] Pre-operational Plants - Plants that are not nor have ever been in commercial operation.

[24] Quality Related (QR) - Any design activity that establishes the methods or means of performing activities associated with structures, systems, and components which are subject to quality requirements and are governed by the Quality Assurance Program, e.g. safety related or controlled by 10 CFR 72, or transportation packages controlled by 10 CFR 71, or other items or other activities as determined on a case-by-case basis. [Reference - QAPM Section A.1 .c] [NP QAPD, Part II, Section 2]

[25] Resulting Documents - Documents required to perform any follow up actions that are required as a result of the calculation conclusion.

[26] Review - The process of assuring that a calculation is technically adequate, procedurally compliant, reasonably accurate, and of sufficient quality to warrant approval and issuance.

5.0 DETAILS 5.1 PRECAUTIONS AND LIMITATIONS

[1] When processing Entergy Nuclear operating plant calculations within IAS, then the electronic forms and associated reviews and approvals are documented in INDUS Asset Suite (IAS).

[2] If processing New Plant calculations or if IAS is not available, then attachments from this procedure can be used.

5.2 GENERAL

[1] A calculation may be utilized for temporary or permanent applications, as necessary, to provide support, basis, and/or justification for existing design, proposed design, preliminary design studies, regulatory/licensing basis, etc., and to establish parameters for equipment performance. If credit is taken for a numerical value in a safety system, in a design basis or licensing basis document, or as an operational parameter, then the basis for that value must be documented. If there is a need to maintain and retrieve the basis for this value, then a calculation should be generated.

NUCLEAR QUALITY RELATED EN-DC-126 REV. 4 MANAGEMENT REFERENCE USE PAGE 12 OF 36 MANUAL Engineering Calculation Process 5.2 cont

[2] Calculations shall be legible and be in a form suitable for imaging, reproduction, storage, and retrieval. Calculations should be sufficiently detailed as to purpose, method, assumption, design input, references, and units such that a person technically qualified in the subject can review and understand the calculation and verify the adequacy of the results without recourse to the Responsible Engineer.[NP NQA-1-1994 Part I Supplement 3S-1, Section 3.1]

[3] Calculations prepared in accordance with this procedure to support a Reasonable Expectation of Operability (REO) do not need to be design verified. Calculations prepared for Operability Determinations shall also meet the requirements of EN-OP-104.

[4] A calculation should not in and of itself be used to initiate or implement a change to the physical configuration of the facility therefore EN-LI-100 does not apply. The associated EC or design change drives the need to engage the EN-LI-100 process.

[5] Operating Plant related calculations:

(a) An Engineering Change should be used to process all calculations for Entergy Nuclear operating plants. Reviews, design verification and approvals of calculations/calculation changes prepared in conjunction with an Engineering Change are documented in the Engineering Change.

(b) Impact Screenings performed in conjunction with the Engineering Change and the initiation of actions to track incorporation of the calculation results are defined by EN-DC-115 and EN-LI-100.

(c) Cumulative effects of Engineering Change Markups (both Pending and As-Built) should be considered whenever preparing a calculation, calculation change or revision.

NUCLEAR QUALITY RELATED EN-DC-126 REV. 4 MANAGEMENT REFERENCE USE PAGE 13 OF 36 MANUAL Engineering Calculation Process 5.2 cont

[6] [NP] New Plant calculations :

(a) New Plant calculations are processed as stand alone documents. No Engineering Change (EC) is required.

(b) As such, associated reviews, design verifications and approvals are transmitted to Administrative Services via the EN-AD-103 process and stored as a record under the calculation number. [NP QAPD, Part II, Section 3.2]

NOTE Editorial Changes, do not require the same review and approval as the original document. [NP QAPD Part II, Section 6.2]

(c) Changes to calculations shall be reviewed and approved by the same organizations that performed the original review and approval unless other organizations are specifically designated or the calculation change is editorial.

[NP QAPD, Part II, Section 6] [NP NQA-1994 Part I, BR 6 and Supplement 6S-1,Section 3.2]

(1) Editorial revisions to calculations are appropriately marked as such on Attachment 9.2.

(2) Editorial revisions are approved by the Manager, Composite Engineering - New Plant. No additional reviewers or verification are required.

[7] Only Approved calculations (including Pending or As-Built EC Markups) results are used for one of the following:

(a) Input into a final document (b) For Operating Plants, Authorization of work activities based on the calculation activities. However, work at risk activities may be allowed with prior approval as defined by EN-DC-115. For preliminary calculations that serve as a basis for a configuration change, approval of the calculation will be tracked by a RTS or Post-RTS item associated with the Engineering Change.

[8] Software utilized for calculations should be identified and tracked on Calculation Reference Sheet (Attachment 9.3), so that notifications of errors or inaccuracies provided by software vendors or end users can be evaluated relative to calculations performed with the software.

NUCLEAR QUALITY RELATED EN-DC-126 REV. 4 MANAGEMENT REFERENCE USE PAGE 14 OF 36 MANUAL Engineering Calculation Process 5.2 cont

[9] The application of computer software shall be controlled in accordance with the software quality assurance (SQA) requirements in EN-IT-104. If the software is exempted as described in EN-IT-104, then the calculation shall describe the method used to verify the software. Software inputs or outputs stored on CDs or DVDs should be transmitted to Administrative Services via EN-AD-103 requirements

[10] [NP] Computer programs used in the preparation of a calculation do not require re-verification for each application provided that the software Verification and Validation (V&V) documentation required by EN-IT-104 demonstrates the following:

(a) The V&V documentation demonstrates that the program produces correct solutions for the encoded mathematical model within defined limits for each parameter employed in the calculation.

(b) The V&V documentation demonstrates that the encoded mathematical model produces a valid solution to the physical problem associated with the particular application.

[NP NQA-1-1994 Part I, BR3 and Supplement 3S-1, Section 3.1(a)]

[11] Input assumptions, parameters and their sources should be clearly identified. This will enable an independent user to regenerate the calculation results. A copy of the input file may be filed with the calculation. [NP NQA-1994 Part I, BR 3 and Supplement 3S-1,Section 3.1][NP QAPD, Part II, Section 3]

[12] Spreadsheet applications, created using Microsoft EXCEL for example, should have the formulas identified in the Methodology section of the calculation or on the worksheet.

[13] If the engineer or the reviewer or the supervisor believe that the plant has been changed and that change is not reflected in the current revision of the calculation then a walkdown should be performed and then plant configuration documented.

[14] If a condition adverse to quality is identified during the preparation of a calculation, e.g. plant configuration is not reflected in the calculation, then the Responsible Engineer should initiate a CR in accordance with EN-LI-102

[15] Limitations and applicability for calculations (e.g., mode dependent load calculations or maximum heat load for areas under certain accident scenarios) should be clearly identified and stated in the calculation purpose or conclusions and in the associated Engineering Change, if applicable.

[16] All actions requiring tracking as a result of approving the calculation should be clearly referenced in the associated Engineering Change for operating plants OR for Pre-operational plants, a Work Tracking (WT) item shall be initiated.

NUCLEAR QUALITY RELATED EN-DC-126 REV. 4 MANAGEMENT REFERENCE USE PAGE 15 OF 36 MANUAL Engineering Calculation Process 5.2 cont

[17] To the extent practical, calculation native files should be stored in a central controlled location (common server, common directory, etc.).

[18] ASME Section III Class 1 Stress Report calculations must be certified by a Registered Professional Engineer. Calculations certified by a vendor do not require recertification.

[19] (RBS Unit 1 Only) Safety related setpoint calculations are developed in accordance with the guidelines given in RBS Unit 1 USAR, Section 7.1.2.5, "NSSS and BOP Safety-Related Set Point Methodology."

5.3 PREPARATION OF CALCULATIONS

[P-24502], [P-25224], [P-22267] [NP QAPD, Part II, Section 3] [NP NQA-1994 Part I, BR 3 and Supplement 3S-1, Section 3.1]

[1] [NP] If preparing New Plant calculations, then go to Attachment 9.5.

[2] Determine the scope, inputs, and outputs.

(a) For safety related calculations:

• Document applicable Design Inputs in accordance with procedure EN-DC-141 or

• Document the applicable Design Inputs in the body of the calculation.

(b) For non-safety related operating plant Calculations, completion of Design Inputs in accordance with procedure EN-DC-141 is not required.

[3] The Responsible Engineer performs the following:

(a) Ensures that a similar calculation does not already exist.

(b) Ensures an associated Engineering Change (EC) is initiated per EN-DC-115.

(c) Obtains new calculation numbers from INDUS Asset Suite Document Management module.

(d) Identifies interfaces between systems and organizations.

(e) Identifies related/affected interface documents including other calculations, FSAR, licensing basis documents, and design basis documents through contact with interfacing departments and use of Impact Screening in the EC Process (EN-DC-115).

NUCLEAR QUALITY RELATED EN-DC-126 REV. 4 MANAGEMENT REFERENCE USE PAGE 16 OF 36 MANUAL Engineering Calculation Process 5.3[3] cont (f) Develops the format and content in accordance with section 5.4 of this procedure.

(g) Prepares the calculation as an Engineering Change markup per EN-DC-132 when changing an operating plant calculation.

(h) Provides justification or substantiation with references when documenting assumptions or engineering judgment as input or in supporting a position.

(i) Documents and validates data supplied through informal communications (e.g.,

telephone, Internet, etc.) commensurate with the impact the data has on the calculation results.

[4] If a calculation is replaced by an entirely new calculation, then the Responsible Engineer should ensure the design conditions enveloped by the original calculation are completely enveloped by the successor calculation or document the basis for the differences and ensure the previous calculation is superseded.

[5] When superseding or voiding a calculation, then the design documents referencing the calculation should be assessed for proper disposition and/or captured in the resulting new calculation. [QAPM B.2.c]

[6] Attachment 9.3, Calculation Reference Sheet is completed to track impacted interfacing documents.

[7] If superseding or voiding a calculation, then other documents that rely on the calculation that is being superseded or voided may need to be revised and shall be listed on the Affected Documents LIST (ADL) of the associated Engineering Change.

[QAPM B.2.c]

[8] The preparer and the reviewer shall consider the amount of margin remaining while preparing the calculation/mark-up. EN-DC-195 provides guidance on different types of margin and controls the Margin Management process. If the calculation reduces the amount of margin that should be discussed in the calculation conclusion.

NUCLEAR QUALITY RELATED EN-DC-126 REV. 4 MANAGEMENT REFERENCE USE PAGE 17 OF 36 MANUAL Engineering Calculation Process 5.4 FORMAT and CONTENT

[1] The recommended format and content for calculations is contained in Attachment 9.1.

[2] Additional sections may be included at the Responsible Engineers discretion.

Conversely, simple calculations that are only a few pages in length may incorporate considerations of Attachment 9.1 into the body of the calculation. When applicable, the section should be clearly labeled.

[3] The Calculation Cover Page as shown in Attachment 9.2 or an electronic equivalent should be used.

NOTE A non design basis calculation can not change the design basis of the plant and is therefore exempted from completing the Calculation Reference Sheet.

[4] Each calculation should include Calculation Reference Sheet per Attachment 9.3.

[5] Every calculation should include a Record of Revisions page, similar to format in Attachment 9.4, including a brief description and reason for the change.

[6] Reformatting of an existing calculation to the requirements of this procedure is left to the discretion of the supervisor.

NOTE

[NP] Section 5.5 is not applicable to processing New Plant Vendor Calculations.

Vendor Calculations are processed in accordance with EN-DC-149.

5.5 VENDOR SUPPLIED CALCULATION[P-24486], [P-15534]

Vendor supplied calculations which are developed under Entergys Quality Assurance program are reviewed and approved in accordance with this procedure. At the discretion of the supervisor of the responsible engineer, vendor supplied calculations which are developed under the vendors Quality Assurance program may be reviewed and approved in accordance with this procedure. Vendor calculations which support permanent modifications to the facility should be strongly considered for processing under this procedure. However, a detailed review of the vendors design reports and other design outputs may be used to provide an equivalent engineering review function when the complexity of maintaining configuration control of the vendors calculations makes this not practical. If the calculation will simply become a record, then it is handled via EN-DC-149.

NUCLEAR QUALITY RELATED EN-DC-126 REV. 4 MANAGEMENT REFERENCE USE PAGE 18 OF 36 MANUAL Engineering Calculation Process 5.5 cont

[1] When selected for review and approval in accordance with this procedure, then vendor supplied calculations should be processed as follows:

(a) Vendor supplied calculations that are prepared in accordance with the Vendor's calculation procedures should be assigned a site calculation number and entered into INDUS Asset Suite as a new calculation. The original vendor calculation number should be added as an alternate reference if the vendor calculation number is not used as the site calculation number.

(b) All design information supplied to a Vendor by Entergy personnel for Quality Related SSCs should be formally transmitted as approved inputs and identified as such in accordance with Section 5.10, Interface Control, of this procedure.

(c) Review Of Vendor Supplied Calculations (1) Vendor supplied calculations should be reviewed for administrative aspects in accordance with EN-DC-149.

(d) Acceptance Of Vendor Supplied Calculations (1) The Reviewer should complete Calculation Cover Page (Attachment 9.2), consistent with Section 5.3 and Calculation Reference Sheet (Attachment 9.3). The Reviewer should enter the Vendor's name in the Responsible Engineer Section of the cover page. If the vendor used Attachment 9.2 as the cover page, then enter the vendors name on the bottom of the form in order to ensure that the name is entered into the site document control system. This technical review:

• Is not a design verification of the calculation,

• Is a check to ensure reasonableness of inputs, assumptions and results, and to verify that the calculation satisfies the sites expectations, as specified to the vendor in the contract and associated design requirement documents.

• Is to identify unverified design assumptions to be processed as described in section 5.9 below.

(2) Design Basis Vendor calculations should be included with the associated Engineering Change (per EN-DC-115); the EC Affected Documents List (ADL) should be updated to reflect impacts due to the calculation.

(3) Upon resolution of comments with the Vendor or acceptance of the calculation with comments in accordance with EN-DC-149, the Reviewer documents his approval and forwards the calculation to the Responsible Supervisor for acceptance.

NUCLEAR QUALITY RELATED EN-DC-126 REV. 4 MANAGEMENT REFERENCE USE PAGE 19 OF 36 MANUAL Engineering Calculation Process 5.6 REVIEWS [NP QAPD, Part II, Sections 3.1 and 6.1] [NP QAPD, Part III, Sections 1.3 and 1.6]

[1] Reviews should be performed as indicated in Section 5.8.

[2] Reviews may vary from a general overview of the calculation to a thorough examination, including a number-by-number check, commensurate with the impact on safety considerations. Calculation reviews may be performed using the Design Verification methods as follows (a) For Operating plants, refer to Section 5.7.

(b) [NP] For New Plant, refer to EN-DC-134.

[3] As a minimum, calculations should be reviewed by the responsible discipline. These reviews are tracked by the reviews of the associated Engineering Change unless a hardcopy calculation is being processed due to INDUS Asset Suite unavailability or the calculation is a New Plant calculation. In this case, all reviews should be documented, by a signature, on the calculation cover page in accordance with Attachment 9.2. Any reviews not performed on the entire calculation should be documented on the calculation cover page.

[4] For operating plant non-quality related, non-risk significant (i.e., outside of Maintenance Rule scope) systems structures, or components where the engineering calculation does not affect any design bases and is not subject to QA program requirements, the responsible supervisor may perform the review and the approval function.

5.7 DESIGN VERIFICATION

[QAPM B.3] [P-26437, P-23961] [NP QAPD, Part II, Section 3.1] [NP NQA-1994 Part I, BR 3 and Supplement 3S-1, Section 4]

[1] Design Verifications should be performed as indicated in Section 5.8

[2] For quality and augmented quality related calculations, any inputs derived from a field walk down or direct component measurement should be documented.

[3] When engineering judgment is used as an input, then the Verifier should evaluate the judgment to ensure it is reasonable and can be substantiated.

[4] The verifier should also determine if all resulting documents have been identified and are appropriately tracked.

NUCLEAR QUALITY RELATED EN-DC-126 REV. 4 MANAGEMENT REFERENCE USE PAGE 20 OF 36 MANUAL Engineering Calculation Process 5.7 cont NOTE In the following situation the Design Verification Checklist and Cover Sheet are not required to be included with the calculation:

• Design Review is the method of verification;

• No comments need to be documented;

• All questions on the Design Verification Checklist are answered YES or N/A; and

• The Supervisor is not the design verifier.

[5] Design verification is performed on quality related calculations in accordance with requirements in procedure EN-DC-134, Design Verification.

[6] [NP] The Manager- Composite Engineering-New Plant may provide Design Verification through the normal supervisory review of non-quality related New Plant calculation involving SSCs that are significant contributors to plant safety. No additional Technical Review is necessary.[NP QAPD, Part III, Section 1.3]

5.8 APPROVAL

[1] The responsible supervisor performs an overall review of the calculation, including:

(a) Ensuring that the calculation achieves the required objectives, (b) Ensuring that the appropriate discipline/organization review(s) occur, (c) Checking that the inputs, assumptions and results are reasonable, and (d) Ensuring that the Responsible Engineer, Reviewer/Verifier have signed and dated the Calculation Cover Sheet or associated Engineering Change as appropriate.

[2] If processing an operating plant calculation within IAS along with an EC, then the Responsible Supervisor signifies concurrence with the calculation by documenting their approval in IAS. The EC and associated calculation will be transmitted to records via IAS as the EC progresses through to closure. [QAPM B.15]

[3] If processing hardcopy calculations (i.e., New Plant calculations, IAS is not available) then approval is signified by the Responsible Supervisor signature on the calculation cover page and is then transmitted by the Responsible Engineer to records via the EN-AD-103 process. [QAPM B.15][NP QAPD, Part II, Section 17]

3) Other reviews may be performed at the discretion of the Responsible Supervisor.

5.9 CONFIGURATION CONTROL

[1] For Operating plants, (a) After calculation is approved in conjunction with the associated Engineering Change, the calculation is retained as part of the associated Engineering Change until the EC reaches Modified or Closed status, at which time the Engineering Change Markup of the calculation revision may be incorporated.

(b) Based on the document update criteria in EN-DC-132, the Responsible Engineer should process the calculation as a calculation revision in INDUS Asset Suite.

[2] [NP] New Plant calculations are processed as full calculation revisions that become as-built upon approval.

[3] The following supplemental requirements should be incorporated into calculations whenever applicable:

(a) Unverified assumptions should be identified in the calculation. A tracking number should be assigned to verify these assumptions prior to returning affected structure, system or equipment to service.

NUCLEAR QUALITY RELATED EN-DC-126 REV. 4 MANAGEMENT REFERENCE USE PAGE 22 OF 36 MANUAL Engineering Calculation Process 5.9[3] cont (b) Design Inputs, assumptions or any parameters used in the calculation, which have an expiration date should be identified in the calculation. Each of these items should be assigned a tracking number from the action tracking system.

Upon expiration of the parameter, the calculation should be reassessed and voided or revised with an updated parameter as applicable. Vendor documents should also meet this requirement.

5.10 INTERFACE CONTROL Interface information is design information that crosses a system-to-system or organization-to-organization boundary and becomes a design requirement for one of these systems or organizations. It may be design input, output, or any restrictions associated with the calculation. A system-to-system interface is physical or parametric information that affects another system that should be identified at the start of the calculation. Interface information may be revised, as needed, until approval of the calculation.

[1] Identification Of Interfaces The identification of interfaces between systems and organizations which affect the development of the calculation by establishing design inputs should be completed prior to the development of the calculation. All design inputs should be identified and documented in the Input and Design Criteria section of the calculation as described in Section 5.3.

[2] Documentation [NP NQA-1-1994, Part I, BR 3 and Supplement 3S-1, Section 6]

(a) [NP] Design information transmitted across interfaces that support New Plant calculations should be formally entered into records and include:

(1) The status of the design information or document provided and, (2) Identify any incomplete items which require further evaluation review or approval.
