,w ERRATA AP600 SCALING AND PIRT CLOSURE REPORT, WCAP-14727 1.
Two acronym errors were noted: ANS is American National Standard (pg 10-40) and LOFT is Loss of Fluid Test.
2.
Figure 2.2-4 shows the pressurizer-to-CMT balance line. This is no longer part of the AP600 design.
3.
Page 2-32: The last paragraph uses "RCS trips."
It should be "RCPs trip."
4.
Page 2-34:
Containment pressure of 24.7 psia appears to be a typo. This probably should be 14.7 psia.
5.
Table 2.4-1:
Canned " water" should be " motor."
6.
Page 4-2 (second paragraph): Discussion on the hot fluid being below the cool fluid should be the other way around.
7.
Page 8-37 (last full paragraph):
"The magnitude of the spike was smaller than one-half of the peak flowrate in Figure 8.4-22."
The subject figure shows the spike to actually be more than 250 times greater.
i 8.
Figure 10.2-1: The last word in the caption should not be " containment."
9.
Page 10-20 (first bullet): The next to last word should be " injection",
not " inspection."
10.
Page 10-21 (last sentence of first paragraph):
" Argument" should be
" agreement." In addition, the last paragraph on this page seems out of pl ace.
