Comparison of indicators for two constrained transients with a magnitude of 10%Pn.

Factors Unit Reference case–5%Pn/min Stressed ramp–10%Pn/min Stressed ramp –15%Pn/min
MW/s 3.25 (5.01%Pn/min) 5.41 (-8.34%Pn/min) 6.39 (-12.86%Pn/min)
s 166 113 99

The reactivity balance between the different cases is slightly different because the balance of the temperatures in the core are modified as a function of the transient.
