. APPENDIX A At-Power Measured ITC Data Reduction In this measurement, the reactivity defect induced by an inlet temperature increase is compensated by an opposite reactivity defect induced by a power reduction. Assuming a value' for the power coefficient, the moderator temperature coefficient can be obtained. The following reactivity balance is solved:

ap

  • AT = 0 .(A.1) in which:

ap is the power coefficient at constant volume average moderator temperature AP is the change in power level at is the isothermal moderator temperature coefficient at constant power AT is the change in core volume average moderator temperature due to the change in inlet temperature A best estimate power coefficient is used in this equation to infer the temperature coefficient. Since relative errors in power coefficients are directly translated into relative errors in temperature coefficients, it is important to have confidence in the best estimate power coefficient.

The core average moderator temperature used in the above equation must reflect the change in axial shape taking place during the test. The changes in moderator temperature due to the change in inlet temperature and to the change in power must be kept separate in the data reduction. Since these effects cannot be measured separately, a test simulation provides a relationship between Tn, i P and T,ye, and a regression is performed to express the core average temperature as a linear combination of inlet temperature and power:

Tove - a *i Tn + b*P (A.2)

This linear relationship, which is valid over a narrow range of the variables, is applied to each pair of measured T n and P to infer Tove.

3

It is interes to note that this definition of T,ye leads to lower values of AT,ye than t..e use of \(T in+Tmt), thus to more negative values of the measured ITC, in better agreement with the predictions.

The data reduction for the three new data points obtained after completion of Reference 2 is summarized in the next three tables. The top half of the table provides the results of the test simulation. Four ROCS calculations are performed at two power levels and two inlet temperatures. The edited core average temperatures and calculated reactivities are recorded. A regression of reactivity vs power and average temperature yield the power coefficient an and isothermal temperature coefficient ar(ITC). The best estimate coefficients are obtained by biasing the calculated coefficients. Then a regression of average temperature vs inlet temperature and power provides the coefficients a and b of equation A.2. The bottom half of the table provides the test conditions, which consist of eight swings of power-temperature. The inlet temperature and the secondary calorimetric power is recorded. The core average temperature is calculated from equation A.2. Then differences in average temperatures and powers are performed between each consecutive swing, and the reactivity defect Ap due to the change in power (at constant core average temperature) is obtained by multiplying the change in power by the best estimate power coefficient. Finally a regression of Ap vs ATove yields ,

the nieasured isothermal temperature coefficient.
