NUSCO GENERATION ENGINEERING DEPARTMENT PROCEDLRE GED 3.09 COMPUTER PROGRAM DOCL' MENTATION AND QUALIFICATION 1.0 PL*RPOSE The purpose of this precedure is to establish the requirements and procedural method for the documentat
. and qualification of all Quality Assurance Category I computer programs.
2.0 APPLICABILITY This procedure applies to all computer programs affe: ting the design of Category I equipment and/or design licensing analyses.
3.0 REFERENCES
3.1 Generation Engineering Department Procedure GED 3.08.
4.0 DEFINITIONS 4.1 QA Category I Cvaputer Program A QA Category I computer program is defined as one whose output is used in the design of a Catessry I structure, system, or component, or is used to qualify this design, or in support and verification of technical specifications, or in the analysis of the operation of safety related items.
If the output of a computer program is used to design more than one structure, system, or component, which have different QA categories, the computer program shall be QA Category I.
4.2 yersion The version designation of a program will be incremental at each revision to the source language software.
4.3 Level The level of a program will be incremental at every signifi-cant change to the job stream (i.e., JCL changes affecting file or library allocation).

4.4 Public Domain Program A program that is generally available to anyone in the industry through a service bureau or other organization.
A public domain program may be copyrighted, has been exten-sively tested, has wide industry acceptance, and may not be modified by individual users without identifying it as a modified program and qualifying it in accordance with this procedure.
4.5 Program Summary A brief description of a computer program, usually one page or less.
4.6 Program Author The Northeast Utilities employee who wrote or is currently responsible for software maintenance or, for non-in-house programs, the respective non-Northeast Utilities person performing a similar program support function.
4.7 Program Sponsor The Northeast Utilities employee assigned to be responsible for a computer program. The sponsor may or may not by the author.
5.0 RESPONSIBILITY 5.1 The program sponsor with or without the author's assistance, shall qualify that the computer program produces accurate results for the selected options and range of applicability consistent with the mathematical models used during its development by one of the following methods.
5.1.1 Manual Qualification Perform one or more manual or computerized calcula-tions using test data for the computer program being qualified.
Compare these results against the results obtained by using the test data in the program.
The program's test results must be proven to be substantially similar.
113S 284 3.09-2 Rev.
Date Page 2 of 10
5.1.2 Comparison Qualification Compare the test results of the program being qualified and the results obtained using a pre-viously qualified method of obtaining the same results, or the results of a presently used Public Domain Program, to verify that both sets of results are substantially similar.
The input data for both methods shall be either the test data developed for the program or other test data substantially similar to the test data.
5.1.3 Qualification of Public Domain Codes Upon acquisition of a public domain computer program, the program sponsor will qualify the program by running test case (s) provided by the specific service bureau or other organization from where the code was obtceed, and verifying test results to be substantially similar to results provided by said organization.
The program sponsor will also verify that the issuing organization, program developers, or other organizations within the industry, have performed acceptable qualification of the program in accordance with paragraphs 5.1.1, or 5.1.2.
This may be performed by reviewing available documentation (User's Manuals, Code Descriptions, Program Applications, etc.) to assess the extent and acceptability of the qualification performed. All documents reviewed by the sponsor shall be referenced and maintained inthe responsible department.
5.1.4 The range of applicability of qualification shall be clearly defined.
5.2 When the Manual Qualification technique is used, documentation for the qualification shall include:
5.2.1 The title, version, and level number of the computer program being qualified.
5.2.2 The documentation of all qualification calculations shall be in accordance with NUSCO Generation Engineering Department Procedure GED 3.08.
Ii35 285 3.09-3 Rev Date Page 3 of 10
5.2.3 A tabulated comparison of the results obtained by a qualification calculations and the program test results.
5.2.4 The range of applicability of qualification shall be clearly defined.
5.3 When the Comparison Qualification technique is used, documen-tation for qualification shall include:
5.3.1 The title, version, and level number of the computer program being qualified.
5.3.2 Clear identification of the previously qualified method or Tublic Domain program used.
5.3.3 Reference to the documentation for the previously qualified method of obtaining the same results.
5.3.4 A tabulated comparison of the test date and test results for the program being qua.ified to the input and results of the previously qualified method.
5.3.5 The range of applicability of qualification shall be clearly defined.
5.4 When the qualification is performed for a Public Domain program, documentation for qualification shall include:
5 4.1 The titla, version, and level number of the computer program being qualified.
5.4.2 Listing of sample case (s) provided by the issuing organization and a tabulated comparison of sample,or test case results will be shown.
5.4.3 Reference to extent and acceptability of quali-fication performed by the issuing organization or other industry organization.
5.4.4 Reference to the qualification of the QA/QC Programs of the issuing organization, if applicable.
5.4.5 The range of applicability of qu-lification shall be clearly defined.

5.5 Documentation Review and Approval 5.5.1 A copy of all documentation requied by Paragraphs 5.2 and 5.3 shall be reviewed by a qualified individual and/or group 5.5.2 When reviewing Computer Programs other then Public Domain, the reviewer shall as a minimum:
s.5.2.1 Verify the validity of the analytical approach taken and the formulae applied.
5.5.2.2 Verify all assumptions made by the author for accuracy and determine if they are reasonable.
5.5.2.3 Verify that the limitations and range of applicability of the program are suffi-ciently def.ned.
5.5.2.4 Verify the basic logic the author has applied to write the program (e.g., are the mathematical formulae properly coded into computer language).-
5.5.2.5 Complete Sections I and II of the " Review and Approval of Documentation For QA Category I Program" form (Attachment 3.09-A) to identify the computer program, the version of the program, the date of publication, and all documentation being c-viewed.
5.5.2.6 Prepare or update the " Computer Program Documentation Log and Historical Develop-ment Ceart For QA Category I Programs" form O ttachment 3.09-B).
5.5.2.7 When oaalification is performed on a Public Domain program, the requirements of section 5.5.2.1, 5.5.2.2 and 5.5.2.4 shall be accomplished by review of referenced availcble documentation of such efforts performed by the service bureau or issuing rganization.
The review of the efforts of said organization and documentation of that review shall constitute compliance to paragraphs 5.5.2.1, 5.5.2.2 and 5.5.2.4.
