Dr. T. K. Shih Applied Physics Department-E8ASCO Services Incorporated Two World Trade Center New York, NY 10048

Dear Dr. Shih:

Thank you for your letter of February 17, 1984 expressing an interest in

! obtaining the most recently released version of the Transient Reactor Analysis Code (TRAC-PF1/M001). The U.S. Nuclear Regulatory Commission (NRC) will_be happy to transmit to you a magnetic tape containing the code and a copy of the draft user's manual provided that EBASCO Services Incorporated (ESI) agrees to the following.

1. ESI will not release the code software to any third party.

2. ESI will immediately notify the NRC of any reactor safety problem which may be uncovered through the use of the code.

3. If ESI discovers code errors, ESI will communicate these errors to the code developers (Los Alamos National Laboratory (LANL)).

4. ESI will make the results of the code use available to the NRC.

( 5. If ESI makes any improvement and/or modification to the code, these a improvements or modifications will be made available to the NRC.

Should code improvements and modifications, or the results of code

l. use, be determined to be company proprietary, the NRC will utilize its procedures to protect such information.

6. If ESI requires LANL assistance to implement and/or use this software, the assistance will be given on a cost recovery basis and will be negotiated in a separate agreement with the NRC.

In interpreting the results of your analyses under Items 2 and 4 above, bear in mind that the TRAC-PF1/ MODI code has undergone developmental assessment, -

but the independent assessment of the code has not yet been completed. We do not warrant the accuracy of the results for any particular use or application.

The signature below of an appropriate official of your company will indicate acceptancdxqf these items. If you accept these terms, I will arrange for the L

N.
