.i April 15,1985 Those on the Attached List Gentlemen:
The purpose of this letter is to clarify the interpretation of the agreement that your company has signed in obtaining the RELAP5/M002, TRAC-PF1/ MODI, or the TRAC-BD1/ MODI code from the U.S. Nuclear Regulatory Commission (NRC). The major clarification involves the proprietary results from code use and proprietary modifications performed on the code by domestic code users. These clarifications are contained in items 4, 5, and 6 below. In effect, the NRC, Office of Nuclear Regulatory Research, does not foresee the direct use of domestic proprietary information in its code improvement and assessment process, and wishes to make this clear in our domestic agreements. Items 1 and 2 simply add minor clarifications to provide definitions of terms. The following 7 items will replace the 6 items contained in the old agreement with the added clarifying statements underlined.
- 1. (Your company) will not release the code software to any third party, unless that third party has also obtained an agreement with the NRC.
- 2. (Your company) will immediately notify the NRC of any reactor safety problem which may be uncovered through the use of the code, as--
reauired by the standard Code of Federal Regulations.
- 3. If (your company) discovers code errors (your company) will communicate these errors to the code developers at (the applicable national laboratory).
- 4. (Your company) will make the nonproprietary results of the code use available to the NRC.
- 5. If (your company) makes any nonproprietary improvement and/or modification to the code, these improvements and/or modifications will be made available to the NRC. Should code improvements and/or modifications or the results of code use be determined to be company proprietary, the NRC will utilize its procedure to protect such information, if NRC requests to receive it.
i
- 6. (Your company) will provide NRC with a nonaroprietary summary of any proprietary modifications to the code whic1 are developed by (your
( company) including a summary of the impact on representative l predictions.
1 If (your company) requires (the applicable national laboratory) 7.
assistance to implement and/or use of this software, the assistance will be given on a cost recovery basis and will be negotiated in a eparate agreement with the NRC.

.o NRC will use this new agreement for future code releases. We intend to honor the previous agreement with your company. However, you may find it advantageous to interpret the agreement that you have signed as described in this letter. Please feel free to contact Dr. Richard Lee ((301) 427-4335), of my staff, should you have any questions.
