INTEGRAL TEST FACILITY CALCULATIONS USING RELAPS/ MOD 3 i'

i Modification of Task 4.1 i

in accordance with Modification No.1 tc NRC-04-96-041, a RE. LAP / MOD 3.2.1.2 code input t

. deck for the ROSA /AP600 test facility has been converted to a TRAC-PWR code input deck.

j After completion of the conversion, during NRC use, the converted deck exhibited problems j

which were not initially anticipated. These problems provide an obstacle to performance of the remaining assessments to be completed under Task 4 of this contract. Therefore, the effort under this subtask is modified whereby the contractor shall (1) resolve the problems identified in the converted input deck sufficient to allow for successful performance of a SBLOCA calculation; (2) perform assessments of the converted input deck, and (3) provide e

l documontation and recommendations regarding lessons-leamed from the input deck conversion. The work to be performed is outlined in the subtasks below.

i, -

4 Task 4.1.A TRAC input Deck Problem Resolution

]

The TRAC input deck recently converted from the RELAP5 deck has shortcomings in performing small-break loss-of-coolant accident (SBLOCA) calculations. The problems j

uncovered by the NRC staff while running SBLOCA calculations must be resolved to allow the calculations to be completed within a reasonable execution time and without frequent stoppage.

j Therefore, to accommodate resolution of these problems, Subtask 4.1.A is being incorporated into the effort being performed under this contract. Under this subtask, the Contrac' tor shall' l

review the attached list of suggested changes, which may redt.ce or eliminate the input deck shortcomings, and shall provide a recommendation on whether all changes on the list should be implemented. After receipt and acceptance of the recommendation, the NRC PO will specify which changes the Contractor shall implement. The Contractor shall provide a revised input 4

deck which incorporates the specified changes.

i Task 4.1.B Small-Break Loss-of-Coolant Accident (SBLOCA) Calculations i

To further eliminate the occunence of problems with performance of calculations using the converted deck, Subtask 4.1.B is being incorporated into the effort being performed under this contract. - Under this subtask, the Contractor shall (i) -

Perform a TRAC-PWR code analysis to assess the latest released version of the TRAC-PWR code against ROSA /AP600 test APDV01 which had a double-ended guillotine break in the Direct Vessel Injection (DVI) line.

(ii)

Prepare an input deck for the latest released version of the TRAC-PWR code for assessment against ROSA /AP600 test APPB01 which had a 2 inch break in the Core Makeup Tank (CMT) Pressure Balance Line (PBL), and provide on-call assistance for completing this PBL break calculation by the NRC staff.

A letter report shall be submitted describing how well the TRAC code predicted the data and explaining the causes for discrepancies between calculations and the data. The report shall discuss which models between TRAC and RELAPS codes produce better predicticas? The assessment should be done based on criteria presented in an INEL report entitled " Adequacy Evaluation of RELAP5/ MOD 3 Version 3.2.1.2 for Simulating AP600 Small Break LOCA," INEL 4

Task 4.1.C Implementation of Lessons Learned from Deck Conversion into NRC's Graphical

}

user Interface Design

. j The input deck conversion work produced a lessons-leamed document describing differences between the RELAP5/ MOD 3.2.1.2 code and the TRAC-PF1/ MOD 2 code in modeling l

component junctions, heat structures, elevation changes, hydraulic diameters, pumps, and I

boundary conditions. To make effective utilization of this experience in future deck conversion work to be performed under this contract, the Contractor shall provide a letter report recommending how this information can be incorporated into the NRC's graphical u er interface (GUI) design. Specifically, the contractor shall develop requirements for TRAC-P 1-D components and heat structure preprocessing and translate RELAP5 components (pipe, snglvol, sngljun, tmdpjun, tmdpvol, heat structures) into TMC-P 1-D components. The Contractor shall delineate how to import or create RELAPS input deck components into NRC's GUI software (SNAP) and create or export TRAC-P 1-D components, thereby decreasing the manual effort and shortening the amount of time required to translate a RELAPS input deck to a TRAC-P input deck, while decreasing the likelihood of making errors. The Contractor shall provide a recommendation on how to integrate the results of this effort into the SNAP requirements and design documents for future use in converting input decks. Specifically, the recommendation shall take into account the lessons learned from converting the RELAPS to TRAC-P deck, especially in the difficult modeling areas, such as the differences between the two codes in handling junctions the difference between the two codes in handling heat structures the difference in the way the two codes handle elevation changes mapping problems (the ability to map component to component or cell to cell) the difference between the two codes in handling hydraulic diameters the difference between the two codes in handling pumps the difference between the two codes in handling boundary conditions These items, as well as the generic translation issue, should be classified into three major areas:

1)

Types of problems which can be handled by a translation algorithm -

2)

Types of problems which will require simple user interaction 3)

Types of problems which will require an expert system to handle user choices For the design, all three types should be addressed in a separate design section for each -

category.

Deliverables Subtask 4.1.A The contractor shall submit a letter report on TRAC input deck problem resolutions. The Contractor shall also submit a corrected TRAC input deck on electronic media (disk or tape) and certify the media to be free of viruses prior to delivery to the NRC. The letter report shall be submitted within 10 months of commencement of work under this subtask. The corrected input deck shall also be submitted within 10 months of commencement of work under this subtask.

Subtask 4.1.B 4

The Contractor shall submit a letter report on TRAC assessment against ROSA /AP600 test data and comparisons between RELAPS and TRAC-PWR code predictions. The TRAC input deck report shall include diagrams and a listing of the input deck. The letter report sha 1 be submitted within 10 months of commencement of work under this subtask.

Subtask 4.1.C The Contractor shall produce a letter report documenting the input deck conversion lessons-j

! earned. The report shall contain recommendations for incorporation of the information into SNAP. The letter report shall be submitted within 6 months of commencement of work under this subtask.

Duration of Subtask.; 41.A. 4.1.B. and 4.1.C These subtasks shall be completed within 10 months after initiation.

Estimated Level-of-Effort of Subtasks 4.1.A. 4.1.B. and 4.1.C The estimated level of effort for these subtasks is 11 staff-months.

NRC Furnished Material The NRC will provide RELAPS and TRAC material as necessary.

Attachment Suggested ROSA /AP600 TRAC Model Improvements 1.

Combine 1-D Hydro Components. There is some computational benefit in combining 1-D hydro components where possible because the code has fewer number of hydro comporients to loop over. Below is a list where 1-D hydro components could be combined.

If all of these were combined, there would be a reduction of 35 components from the current 135. I am not advocating that all these hydro components be combined. There are logical reasons for having separate 1-D components. The cited figure numbers are the figures in the ROSA /AP600 model description report SCIE-NRC-252-96, Revision 0.1.

Missing heat-structure modeling. There appears to be no pipe-wall heat-structure modeling for the following components; Fig.10 Pressurizer surgeline component 600, ADS stage 4 components 671 and 672 and steam-generator outlet plenum component 428 1

Fig.14 Accumulator components 101,102,168, iii, and 103. Not having pipe-wall heat structure modeling for the accumulator tanks may affect accumulator flow injection because the tank wall heat capacitj will help keep the accumulator gas temperatures from decreasing too rapidly.
