Abstract

The actual temperature rises in the fuel assemblies depend on the state of the unit. In the computational model only an ideal state can be given, that state is close to the actual core state. To account for the difference between the actual core state and the ideal state, we correct the ideal state by a set of functions, the so-called trial functions. The most important trial function is the ideal state supplied by the computational model. Further trial functions account for corrections in control rod position, flow rate changes in MCPs.

Footnotes
1
It can be shown that only the one-sided continuity is needed.
 
2
The probability that equal values occur is zero.
 
3
When one-sided upper tolerance limit is needed then (5.15) is replaced by
$$\begin{aligned} \frac{1}{\sqrt{2\pi }} \int _{-\infty }^{\mu +q} e^{-x^2/2} dx=\gamma . \end{aligned}$$
