Q

During 40EP-9EO09 Functional Recovery, What condition must be met for RCGVS to be EFFECTIVE?

A
  • RCS subcooled
  • Bubble will form and hold pressure if not
17
Q

Where can each train of RCGVS be vented to?

A

A - CNTMT

B - RDT

18
Q

When operating AFA locally, what is the concern when lowering SG flow?

A
  • Overspeed trip
  • Less work, same steam flow => speeds up
19
Q

During 40EP-9EO09 Functional Recovery, HR-1 addresses which casualties in which order?

A
  • SGTR
  • ESD
  • LOAF
20
Q

During 40EP-9EO09 Functional Recovery, with a ruptured/ faulted SG, what is the required feed rate, level and why?

A

45 - 60% NR

1360 - 1600 gpm

  • 1360 - reduce offsite dose
  • 1600 - stress on SG (water hammer/ thermal)
21
Q

During 40EP-9EO09 Functional Recovery, what is the MINIMUM level to minimize offsite dose with a Ruptured/ Faulted SG?

A
  • Above SG tubes
  • ≈ 22% NR
22
Q

During 40EP-9EO09 Functional Recovery, how long do you have to start feeding a Ruptured/ Faulted SG?

A
  • 16.67 minutes TCA
23
Q

During 40EP-9EO09 Functional Recovery, how many AF pumps do you feed with? why?

A
  • 2
  • AFA will not provide enough feed alone
  • 3 pumps could exceed max flow for feedring (2000 gpm)
24
Q

During 40EP-9EO09 Functional Recovery, what are the requirements to use LPSI for CS flow

A
  • CSAS actuated
  • Unable to maintain 4350 gpm
  • LPSI pump not needed
  • LPSI < 60 amps
  • THERE WILL BE NO FLOW INDICATION
25
Q

What are the guidlines for stopping CS pumps?

A

Both on miniflow and not expected > 8.5 psig in 1 hour

< 5 psig, not needed for iodine removal/ H2 mixing and one of:

  • CNTMT cooling restored
  • SDC in svc

Stop 1 CSP:

  • < 50 psig, SI flow adequate
26
Q

During 40EP-9EO09 Functional Recovery, when are Long Term Actions implemented?

A
  • All success paths perfomed
  • SFSC for paths satisfied
27
Q

During 40EP-9EO09 Functional Recovery, what is the NORMAL SDC entry criteria?

A
  • Lpzr > 30% [38]
  • ≥ 24°F [44] subcooled
  • Ppzr < 385 psia
  • Th < 335°F
  • RCS activity wont make AB unacceptable
28
Q

During 40EP-9EO09 Functional Recovery, what is the LOSS OF SUMP RECIRC SDC Entry Criteria?

A
  • Ppzr < 385 psia
  • Th < 335°F or REP CET < 350°F
  • RVUH ≥ 16%
  • RCS activity ok for AB
