STATEMENT OF WORK TASK ORDER #7 " SNAP Nodalization Knowledge-Based Expert System" Bact: ground The NRC began development of a graphical user interface (GUI) for its thermal-hydraulic (1/H) codes with four primarf goals: increase ease of use of the T/H codes, maintain investment in existing input decks, decrease the user effect, and provide a productive work environment for,.
analysts including configuration control of their analysis projects. This GUI work culminated in a requirements and design documents from which an inCal version of the Symbolic Nuclear Analysis Program (SNAP) was produced, focusing on the preprocessing for REl.AP5.
Significant improvements to this code included a redesign of the underlying classes, and the untangling of components as they.were imported. This improved version of SNAP was presented to various users for Beta Testing. Tho development of additional features for the RELAPS preprocessor wit were found to be lacking during the Beta Testi.1g, and a runtime/ output visualizat.on capability are now planned.
Once the SNAP basic user interface engine is developed, NRC would like to implement knowledge-based expert systems (KBES) to standardize and codify procedures to handle complex tasks associated with the use of T/H codes so the' code users no longer have to rely on the trial and error approach when using the code. The development of code input decks is a complex task that is now being facilitated by SNAP. Under this contract, an KBES will be developed to aid the user with input deck nodalization.
Objectives The objectives of this contract are:
1.
To develop recommended nodalization schemes based on the knowledge and experience of expert users; li.
To provide a basic automatic nodalization system to the SNAP code; iii.
To provide feedback to the use, (o suggest an attemative nodalization scheme for a particular situation when the user has violated nodalization recommendations; iv.
To identify other areas where expert systems can provie SNAP the capabilities with which to meet the goals of the NRC GUI.
Work Requirements All new documents will be created and delivered to the NRC in FrameMaker 5.5 format, except for project reporting, which maw be done via e-mail. All coding shall be performed within a version of SNAP provided to the contractor by the NRC technical monitor.
.. Task 1: Ider*y Nodalization.KBES Requirements and Design.
The contractor shall interact with T/H code users and developers and SNAP developers to identify the issues associated with noding the T/H model and organize the knowledge and techniques of the expert users 17to a series of recommendations for noda'ization schemes.
These recommendations, which are based on knowledge that has been refined over years of
2 code use, shall be suggested to the user through a nodalization KBES. The nodalization scheme recommended shall be a function of the particular design modeled and shall be -
component specific. To deveicp these recommendations, the contractor shall investigate the following topics:
a.'
the impact of noding on the T/H modelin view of the wide range of transients modeled-
~
by NRC T/H code users (specifically, guidelines used to ensure the nodalization is consistent with the numerical scheme and physical models in the code);
b.
the impact of noding, on the run time and convergence rate; c.
the components in NRC's T/H codes that would benefit from automatic nodalization; d.
the interface. requirements associated with implementing an automatic noding system in SNAP.
~
The KBES shall utilize the information collected as topics a-d are investigated and recommend a nndalization scheme, that the user shall have the option of accepting or rejecting. If i
accepted, the recommendations shall be implemented into a default nodalization scheme. The scheme shall be designed to be component specific as different nodalization strategies are implemented when modeling compont.nt specific behavior. The expe#, systam shall use artificialintelligence as a means of refining the recommendations which serve as tha basis for the nodalization systcm, so that the system shall be capable of optimi7.ing the nodalization through repeated use. Robustness and run time Wi serve as the figures of merit by which the system measures success. However, guidelin., on accuracy, collected when investigating topic a, shall not be violated, After the program has been designed, a document shall be written detailin0 these requirements, to be included as a chapter in the SNAP requireme qts document. This document ahall be delivered by February 27,1998.
A chapter for the SNAP design document shall be prepered detailing the proposed design of the automatic ncding system, which shall be delivered by March 1,1998.
Completion Date: March 1,1998.
Task 2: Implementation of the Noding System into SNAP 4
The contractor shall implement the KBES described in Task 1 into SNAP. This implementation shall be closely coordinated with the NRC technical monitor to avoid conflicts with other changes being made to SNAP.
A version of the nodalization system shall be delivered by June 12,1998 for inclusion into the main SNAP code.
NRC shall review the work and 'make commeats that must be incorporated into a new version of the nodalization system by September 30,1998.
Completion Date: September 30,1998
3 Task 3: Documentation A programmer's guide shall be developed as an appendix to the SNAP design document, which describes the nodalizahon system code structure and provides a listing and brief description of the major classes, including a listing of their variables and member functions. The manual
'shall be' updated as chMges are made to the nodalization systemr 4
m The user manual documentation shall be developed in FrameMaker 5.5, emulating a conventional text manual with table of content hyperlinks. It shall be updated concurrent with changes to the nodalization system. Both the FrameMaker version and HTML version exported from FrameMaker shall be distributed with SNAP.
Completion Time: September 30,1998.
Task 5: Testing Testing of the runtimt.Joutput visualization code shall be performed on a series of REi.APS problems provided to the contractor.
Completion Date: September 30,1998.
Task 6: Identification of Expert System Needs for SNAP The contractor shall prepare a white paper identifying areas whcre Expert Systems could be implemented into SNAP to meet its primary goals: increase ease of use of the T/H codes,
- maintain investment in existing input decks, decrease the user effect, ano provide a productive work environment for analysts including configuration control of their analysis projects.
For each area identified, the white paper shall recommend specific systems and describe how they would be implemented into SNAP, how they would appear to the user, and the physical or thermal-hydraulic theory behind each proposed system.
A draft version of this white paper shall be delivered by June 1,1998, for comments by the NRC A final version of the white paper, incorporating NRC comments, shall be delivered by August 1,1998.
Completion Date: September 30,1998 Del!verables 1.
