AP-20 (cond tube leak)

Question 1

AP-20 (cond tube leak)

What are the Rx trip criteria while in AP-20?

Answer 1

Cond CatCon > 1.0 micro S/ cm (not in procedure if less)

and

FCV-230 open

OR

FW Cat Con > 0.25 micro S/ cm

OR

Cond CatCon > 200 micro S/ cm (after ramp -> 20%)

Question 2

What are the symtoms/ entry conditions for AP-20 (cond tube leak)?

Answer 2

• Chemistry reports OOS
• polisher reports indication of salt leak
• abnormal conductivity on PPC

Question 3

Per AP-20 (cond tube leak) att. 4.1, what are the ramp rates and correlating conductivities?

Answer 3

Cond CatCon ramp rate final pwr

1-4 5 mw/min 50%

4-15 5 mw/min 50%

15-150 25 mw/min 50%

150-200 50 mw/min s/d
