Question 4

3 methods to remove heat from the core

Answer 4

1. transfer heat to mainfeedwater via steam generator
2. transfer heat to ccw via rhr hx
3. transfer heat to containment atmosphere via pzr porvs

Question 5

least desirable method to remove heatr from the core

Answer 5

feed and bleed via the pzr porvs

it creates a loca in containment
