1-A TUGC0/TUSI CPSES QA Plan 2.0 GENERAL 2.1 PURPOSE The purpose of this procedure is to specify the require-ments for design verification for Comanche Peak Project Engineering (CPPE) designed projects to ensure that a new or revised design adequately satisfies its intended function.
2.2 DEFINITIONS - - - - .
2.2.1 Desian Verification - The process of reviewing, confinning or substantiating the design by one or more methods to provide assurance that the design meets the specified in-puts. Acceptable verification methods include but are not limited to Design Review, Alternate Calculations, and Qualification Testing.
2.2.3 Alternate Calculations Design verification method that employs comparison with alternate calculation or analysis. The alternate method may be a more simplified or less rigorous approach.
2.2.4 Qualification Testing Verification achieved by suitable testing of a prototype or initial production unit.
2.3 RESPONSIBILITIES The Original Designer shall authorize their personnel -
at the site or in the CPSES Project Engineering Group to perfonn design reviews / verifications.

TEXAS UTILITIES SERVICES INC. REVISION PAGE CP-EP-4.5 1 2-18-80 2 of 3 3.1 GENERAL Design verification shall be done in accordance with sub-ordinate instructions that outline the requirements and/
or the method (s) to be used.
Design verification shall be performed by other than the one who performed the original calculation.
When verifying changes to a previously verified design, verification shall include an evaluation of the effects of these changes on the overall design.
Design verifications will be verified by the original designer when applicable.
Deficiencies identified during design verification shall be identified, documented and resolved as per the require-ments of Reference 1-A.
Acceptable methods for design verification include Alter-nate Calculations and Qualification Testing.
3.2 ALTERNATE CALCULATIONS When using alternate calculations for design verifciation,
- a. Appropriateness of assumptions, input da;a and .the code requirements used during the original calculations shall be reviewed; (e.g. hand calculations vs. computer)
- b. Even if the simplified alternate calcuiations do not exactly check the original calculaticas, they must be consistent with the original cairJlations.
3.3 QUALIFICATION TESTING When verifying design by qualification testing:
- a. Qualification testing shall be designed to demonstrate adequacy even under the most adverse conditions.
- b. If qualification testing is designed to verify a spe-cific design feature then the other features shall be verified by other means.
- c. It shall be performed in accordance with procedures which make provisions for insuring that the pre-requisites have been met, adequate instrumentation is available and that necessary monitoring is performed.

The card should be filled out using a black ink pen or " dark" pencil.
- a. Serial No. - Prenumbered, or as established through detailed application instructions supplementing this procedure.
- b. Section 1, Application - State generic category of work (e.g. mechanical equipnent, electrical equipment, pipe, pipe supports, etc).
Weld Mod., Q, Non-Q - Check appropriate block.
Design Change Deviation - Cross out the one that cbes not apply.
Enter N/A or leave blank if not a change or deviation to design.
- c. Section 2, DW. Ib. - Enter the complete number and revision of the affected design basis and/or construction drawings as follows:
- 1. Electrical - Enter desiga b-eis drawing nwters.
- 2. Pipirg and Instrumentation - Enter the design ard construction drawing numb ~ - 'or all design change / deviations; and construction drawing nurters for construction changes.
- 3. Pipe Supports - Enter the construction drawing nwbers.
- d. Section 3, Line No./Conponent Ib. - Enter the specific identification nwber of the component to be nodified; spool nwber, equipment number, etc. It is not required to enter the pipe support nwter in block 3. If a nwber of items are affected, enter "see sketch", and
- show all changes in block 5.
- e. Section 4, Peason for Change - State briefly but concisely the reason for the change. If to implement a change properly approved by the Original Design, clearly state this fact (e.g., 'Ib implement DE/CD 8600).
- f. Section 5, Instructions - Inscribe completely and accurately the change to be made.
- 1. Where there are no welds or material removed or added, enter "N/A" in the a@ropriate blocks.
- 2. For removal and/or addition of welds and/or nuterial, check the awropriate block and enter all weld numbers and/or Bill of Material item nurrbers removed and/or added. It is tot nundatory to disposition the future use and/or storage requirements for deleted material. .

- 3. EOR PIPIN3 ONLY AND INTEGRAL HANGER A'I'rACHMENTS - If, after the original issue of BRP drawing, a weld has to be recoved and rewelded, the weld number will be changed to indicate same by adding an "A" for the first renoval, "B" for the second remval, etc. to the weld numbers, e.g., for the weld 6, the first removal / reweld is 6A, ard if 6A requires rework, the second renoval/ reweld is 6B.
- 4. FOR PIPING OILY - hten stainless steel materials are re-used and the heat affected zone not renoved, the new weld number will include the next sequential letter of the item with the highest numerical weld number.
For exaxple, if the pipe between welds 7A and 8C is deleted, and the remaining parts welded together, the new weld nu:ter will be 8D, not
- 78. In the situaticn where weld 6A is cut and a pup installed between the two pieces, the new welds will te numbered 6B and 6A-1.
- 5. PIPIN3 ONLY - If, after the original issue of the BRP drawing, an added weld is required which is not a reweld of an existing weld; the new weld will be keyed to the 1cwcr of the tw numbered welds ard suffixed by "-1" for the first weld, "-2" for the second weld, etc., if a weld is added between weld "3" and "4", the new weld will te "3-1".
- g. Section 6- Provide a sketch indicating the new arrangement when necessary for clarification. hten nere than one CFC affects a drawing, care shall be taken to avoid conflicts tetween the C4C's. This block should include specifications of items added that are not listed on the affected drawing.
It should also show new weld locations, and all required working reint dimensions (cut lengths for pipig and hangers are not required).
- h. Section 7 - Originator - Enter the name of the individual preparing the modification (for pipirg changes, foreman requestire the change should be entered).
- i. Section 8 - Approvad By - Approval shall be obtained in accordance with Section 3.2.2.
- j. Section 9 - Distribution - If not predesignated, the Engineer / Technician preparire the CSC shall enter the name of each agency requiring an
" Engineering nd Office Use Only" copy and shall indicate the number of required copies for each.
