Self Study AOPs (RB Int, Liq and Gas Rad Hi)

Question 1

What are the entry conditions for Loss of RB Integrity?

Answer 1

Question 2

What actions are required per TS 3.6.1 if RB inoperable?

Answer 2

In mode 1-4, if RB inoperable then restore within 1 hour and be in mode 3 within 6 hours if not restored operable.

Question 3

What actions are taken to correct conditions associated with spurious trips of gaseous and liquid radwaste monitors (RE4830/4642) due to spiking or rising background levels?

Answer 3

K10 ACA for RE4830, not the AOP which will allow resetting process monitor for an instantaneous spike and recommencing release if in progress.

For RE-4642, if trip wasn’t caused by unplanned release then re-establish release.

Unplanned release defined as unintended discharge of a volume of liquid or airborne radioactivity to environment. If unplanned release occurs then direct chemistry to determine extent of release, implement EALs and reference ODCM.

Question 4

What occurs in gaseous system if RE-4830 trips?

Answer 4

CV-4830 and CV-4820 close and CV-4806 opens to begin compressing to T-18s.
