Dear Mr. Rodriguez:

SUBJECT:

TASK ORDER NO. 7 MODIFICATION NO. 3 ENTITLED " SNAP NODAllZATION KNOWLEDGE-BAGED EXPERT SYSTEM" UNDER CONTRACT NO. NRC 97-046 In accordance with Section G.4, Task Order Procedures, of the subject contract, this letter definitizes Task Order No. 7 Modification No. 3. This effort shall be performed in accordance l

with the enclosed Statement of Work for Mod 3 (Tasks 7,8 and 9 only). Tasks 10,11 and 12 are left as undefinitized unpriced options which may be renegotiated and definitized at a later time.

The period of perf mance for Task Order No. 7 is changed to run from January 14,1998 through September bu,1999. The total estimated cost for full performance of this task order is increased by $24,360 from $129,729 to $154,089. Funds obligated on this task order are increased by $24,360 from $129,729 to $154,089. The Contractor shall not incur costs for this task order which exceed the cumulative obligated amount of $154,089.

MODIFICATION NO. 3 TO TASK ORDER #7 OBJECTIVES This modification will add the following objective to the task order:

Develop a stability module to the Nodalization KBES that will identify numerically induce oscillatory thermal-hydraulic conditions and inform the KBES so that the nodalization scheme can be improved.

i WORK REQUIREMENTS Task 7: SNAP Interface Propose a method of accessing the Nodalization KBES through SNAP, such as throuah a CORBA interface, so that SNAP views the KBES as a function call that outputs a SNAP formatted file that can be read by SNAP and used to develop an input deck. This work is essentially the original intent of Task 2, which was modified, since the Windows NT version of SNAP was not completed in time for the implementation to be completed. This task will therefore build off of work done under Task 2 and will not be duplicative.

A letter report in both text and electronic format shall be provided to NRC. The report shall be chapters in the SNAP User's Manual and SNAP Programmer Appendix and SNAP Design Document. Once accepted, this design can be implemented. The implementation shall be on both the Windows NT and Unix platforms, and the updates to both SNAP versions shall be provided to NRC in electronic format to be accepted into the SNAP configuration control system.

Estimated Completion Date: 1 month after initiation of the modification Estimated Level of Effort: 0.5 s/m Task 8: Thermal-Hydraulic Oscillation Criteria Report The approach that if the oscillations cannot be identified as physically based, then they must be numerically induced will be used to identify the phenomena. Therefore, the chysics of thermal-hydraulic stability must be studied and catalogued. A letter report shall be submitted to NRC in both text and electronic format summarizing all possible thermal-hydraulie uscillations, identifying the geometries and conditions under which they occur, methods to evaluate their frequency and all techniques that can be used to identify them. This information will be implemented into the expert syst an as the means of diagnosing the behavior. NRC will provide consultation with thermal-hydraulic experts.

Estimated Completion Date: 2 months after initiation of the modification Estimated Level of Effort: 1 s/m Task 9: Software Requirements Document A chapter for the SNAP Requirements Document shall be prepared and submitted to NRC in both text and electronic format that outlines the requirements of the oscillation diagnostic system. The system must interface with SNAP and the Nodalization KBES as well as accept

7 data ' rom the code as it runs (the results from each time step are not recorded in the dump files, so that the frequency of the oscillations may be masked by the plot frequency specified by the user). AC reouirements, such as the interfaces fo the SNAP front and back ends which must provide both geometric and thermal-hydraulic data, the interface to the Nodalization KBES to help the KBES learn better nodalization schemes, and interaction with the code's time step control if the oscillation is numerically induced, shall be discussed.

Estimated Completion Date: 3 months after initiation of the modification Estimated Level of Effort: 0.5 slm MEETINGS AND TRAVEL For successful completion of the work required in this contract, it is anticipated that the contractor shall travel to the NRC office in Rockville, MD. All travel shall be approved in advance by the Project Manager, be specifically performed in support of this contract ans t;e in compliance with Federal Transportation Regulations.

Tasks 7,8 Upon completion of Task 8. one two-day meeting for two people.
