EOP-SGTR-2 — Post SGTR Cooldown
Purpose
Provides guidance for cooldown following successful mitigation of a steam generator tube rupture when SI has been terminated and subcooling is maintained. This is the normal recovery path from EOP-SGTR-1 when the SGTR is isolated and plant conditions are stable.
Key Actions / Information
Exam — 2020 Q79
EOP-SGTR-2 is a possible transition from EOP-SGTR-1 for post-SGTR cooldown. However, if SI has been terminated and RCS subcooling reaches 0°F, the correct transition is to EOP-SGTR-3 (Subcooled Recovery), NOT EOP-SGTR-2.
