Task 4 - Verification of Exxon Technique for Stability Calculations Purpose Exxon Nuclear Corporation is developing a method for predicting instabili-This method uses a version of the subchannel code ties in a BWR core.
COBRA coupled with a neutronics code to calculate the nuclear feedback.
The purpose of this task is to audit COBRA's capability to accurately predict the thermal-hydraulic aspect of the core instability calculation.
No attempt will be made to couple the COBRA code with a neutronics code.
Work Scope The paper by E. Quandt, " Analysis and Measurements of Flow Oscillations,"
1961 (copy enclosed), provides Chem. Eng. Prog. Symp. Sec., 57, 32, Ill, In these tests, experimental data for parallel channel flow oscillations.
flo.< oscillations were observed over a pressure range of 600 < PS 1600 73%.
psia and over an exit quality range of 23 < x <
This task consists of using COBRA-IV to model the test geometry and test These conditions for each of the tests described in the Quandt paper.
flux for the calculations are transient tests and the flow and/or heat should be varied as in the tests.
The principal calculatic. 21 components to be compared with the test data are:
1.
Conditions at onset of instability, Frequency of oscillations',
2.
3.
Prediction of DNB if DNB occurred in the test.
2228 073
Page 4 The use of COBRA-IV for these calculations, as opposed to other versions of COBRA, is requested because the execution time for COBRA-IV is shorter than for earlier version of COBRA when transients are calculated.
Article II - REPORTS The contractor shall submit a final report prepared in accordance with NRC Manual Chapter 3202.
The report shall contain the detailed descrip-tion of the results of the task work performed and of the models and assumptions used in the analysis.
The report shall be sub'mitted to:
M. Wayne dodges, DSS (3 copies)
- 2. R. Rosztoczy, DSS (1 copy)
D. J. Dougherty, Contracting Officer (1 copy)
A'Pticle III - PERIOD OF PERFORMANCE The period of performance shall be from the effective date of the contract through August 31, 1979.
