Behavior of
temperature, pressure, and
power as a function of time
(s) in the core and steam
generator (SG) after an
emergency power case
without scram [

] (example
of analysis for a
KWU-PWR)
accordance with fracture mechanics (Sect.
5.6.4
) as 0.1F (F
pipe cross section).
However, for the design of the emergency core cooling system, the larger so-called
2F break (guillotine type rupture of pipe) is analyzed conservatively [

]. This
highly conservative case will be described here by way of example in Fig.
5.14
.
