1. Error Analyses and Corrections (a) Platform and Time Dependence Numerical Problems At the June CAMP meeting, users identified a number of code problems in which results of code calculations reveal time step and platform dependency. There is also a tendency to predict unphysical oscillatory responses that is eliminated at very small time step size. This task is to identify root causes for these problems sad implement modifications to reduce the numerical problems. A brief plan (not more than 2 pages) shall be submitted within one moth for the NRC review.

Deliverables: A report summanzes nature of the problems, improved models cand ,,

l results of assessment shall be submitted with the updated source code at the l completion of the task.

Estimated Level of Effort: 12 staff-months Estimated Completion Date: 5/1/99 l 2.1 SNAP / MOD 1 l

The main objective of this task is to incorporate in the SNAP code a capability to translate exiating input decks for the RELAP5, TRAC-B and TRAC-P codes into those for the consolidated T/H code. The envisioned process of translating the input decks, and relationship among programs and files mentioned in this task are shown in Figure 1.

task needs to be coordinated with LANL, the NRC contractor who is working on the TRAC-M code to facilitate such translations.

(a) Importing and Layering of Information This subtask shall incorporate in SNAP the capability to read and parse an existing input model and store the information in an intemcl data structure which is organized by runtime information and component information. The component structure will be layered into physical, nodalization and code-specific information.

The contractor shall incorporate in SNAP capabilities to import / export additional RELAP5 components such as material properties, pump and ECCMIX properties.

The dialogs to create or modify code options, heat structures, and trip and controls information will be expanded and made easier to use. Th3 contractor

( shall also create new classes as necessary to partition some information further to facilitate layering of information in SNAP. I l

l

- Layering of information within the Preprocessor /Initializatiot, module in TRAC-M (Preinit) will be performed by LANL under W6245. Scientech shall coordinate with the Preinit contractor to ensure compatibility of the data s'ructure.
