review, and control of all manual and computerized engineering and design calculations.

-;,z 2.0 GENERAL l

All manual and computerized engineering and design calculations shall be:

r i.,

l Prel,ered such that the analysis can be understood by an T

individual ccanpetent in the calculation discipline l

withou. recourse to the preparer of the calculation.

Legibly' documented in a form suitable for microfilm, 9

microfiche, and/or xerographic reproduction.

12.0 D_UPLICATION REQUIREMENTS Calculations prepared for another project and Division c

standarc. calculations may be duplicated provided that:

'2he duplicator has determined that the calculation to be duplicated adequately meets the requirements of the duplicating project.

The calculation's existing documentation provides all

+

the information required by Attachments 1.1 through 1.5

' to this

EAP, or the existing documentation can be supplemented by the duplicator to meet these requirements.

A copy of all documents that are identified as sources of input and those documents necessary to understand the calculation or verify its adequacy are obtained, or are maintained in a manner that satisfies the permanent l

plant record requirements of the duplicating project (see EAP 17.2).

For nuclear power projects QA Category I calculations only, the calculation to be exactly duplicated has been previously reviewed by an Independent Reviewer.

NOTE:

If the calculation to be exactly duplicated has not been previously reviewed by an Independent

Reviewer, the duplicate calculation shall be prepared according to paragraph 3.3 and then independently reviewed.

13.0 PREPARATION AND OUALIFICATION OF PREAPPROVED CALCULATION METHODS 13.1 Divisions may prepare a manual or computeri=ed Preapproved Calculation Method that is intended for repeated use with calculations having the same objective.

Computerized 1

Clear identification of assumptions used in constructing the method.

13.3 A Preapproved Calculation Method must be qualified, before

use, as follows:

i A manual calculation method shall be qualified by the preparation of a typical calculation using the method.

The typical calculation shall be prepared, reviewed,

('

and approved according to the requirements of this EAP, and shall be included as part of the Division documentation.

NOTE:

For nuclear power projects QA Category I methods only, the typical calculation prepared to qualify the method must be Independently reviewed.

A computerized calculation method shall be qualified according to the requirements of EAP 5.25.

14.0 RELATED PROJECT AND DIVISION PROCEDURES / DOCUMENTS 14.1 E,ach Project Engineer shall issue a Project instruction to establish a system for numbering calculations prepared for the Project.

14.2 Each Division shall prepare a Division technical procedure that establishes the following:

A system for numbering or otherwise identifylng preapproved calculation methods prepared by the Division.

For other calculations, the alternate calculation shall be included when warranted due to its complexity.

In addition, ensure that the J source documents have been identified in a manner that orovides tor oositive traceability.
