APPENDIX A
Format for Calculations
1. The calculation title, document number (assigned using HDNS), revision number, and page
number (using “1 of X” format where X is the total number of pages) are included on each
page of the calculation. Computer sheets inserted into the calculations are numbered in
sequence where they appear. Computer sheets used in an appendix are numbered as
appendices, using uppercase letters and numbered within each appendix (e.g., A-1, A-2, B-
1). Only the Calculation Checklist (A-6007-113) of calculations require the originators and
checker’s signatures and dates. In handwritten calculations, inserted pages resulting from
calculation revisions are identified with alpha suffixes. For example, if two pages are
inserted after page 3, they are identified as pages 3a and 3b respectively. The total number
of pages is reflected on the calculation cover sheet. Calculations are initially issued
Revision 0. Future revisions, if required, are numbered Revision 1, 2, etc. All signatures
must be in ink.
Provide the following sections in the calculation.
2. Cover Sheet. Use Calculation Checklist, (Site Form A-6007-113), as the cover sheet for
calculations to be included in an FMP. Use the HDNS to generate a cover sheet for a
standalone calculation to be released in DMCS.
3. Table of Contents. Provide an optional Table of Contents depending on the size and
complexity of the calculation. A Table of Contents is not required for a short simple
calculation.
4. Purpose . Provide a section that describes the reason for performing the calculation, the end
result sought, and any alternatives examined.
5. Summary of Results . Provide an optional summary. For long and complex calculations
provide a summary of results in this section. This section should include results and
conclusions along with any limits or criteria needed to evaluate the results. For a simple
short calculation the results may be provided in Section 10.
6. Assumptions. Provide a section listing the relevant assumptions necessary to perform the
calculation, including a brief explanation of the basis for each, if applicable.

7. Software Applications, Descriptions, Installation & Checkout, and Statements of Validity.
Software used to perform calculations may be utilized in one of two ways:
a. Single Use - Single Use applies to software created and used for one specific instance only
and which is wholly incorporated into and documented by a technical report. This requires
that all inputs, mathematical formulas, and output data are able to be exactly verified during
technical checking of the calculation. Single Use software is validated in a manner similar to
hand calculations. This requires that all equations are presented such that the calculations can
be reproduced for checking. Single Use software (typically created with Excel, Mathcad, or a
calculator) may have its results validated by any of the following methods:
Comparison with hand calculations,
Comparison with calculations using comparable proven problems,
Comparison with information from confirmed published data,
Comparison with other validated computer programs,
Comparison with experiments and tests.
b. Approved Software - Approved Software (e.g. ANSYS, RISA3D, etc.) shall comply with
requirements of MSC-PRO-IS-309. Software used shall be registered on the Hanford
Information System Inventory (HISI) and identified as approved for use. Each use of
Approved Software shall be logged in HISI in accordance with MSC-PRO-IS-309. For
Approved Software, provide a section that includes the following information:
1. Description:
Identify the following for the software package used in the calculation:
Software Title
Software Version
HISI Identification Number
Workstation type and property number (from which software is run).
2. Software Installation and Checkout
Reference or include a copy of the Software Installation and Checkout form for the
workstation used.
3. Statement of Valid Software Application
Brief statement confirming correct application of the particular software to the
problem being solved.
Brief statement confirming software has been used within its limitations (e.g.,
comparison of the problem inputs against the software's required range of variables to
determine if the problem fits within the software limitations.
