r If the system void fraction evolves to >15% during.a small break while pumps are running, is the 95: SG 1evel important for core cooling? Please adviso.

[

My thoughts are:

1.

SG level important for safety only at 951 with pumps off,

2.

If break size, which would evolve >15" void does not need 95: Icvel, level instru=entation errors caused by high contain=ent tc=ps, etc.

not imporwant 3.'

Vould simplify operator's life if this is so n
