Given the following plant conditio ns:

The plant is operating at 100% power with 1B CCP in service .

The Control Room Operator shutdowns down the C-A ERCW pump in preparation for a test on the

Rises

B.

Remains constan t

DISTRACTOR ANALYSIS

a.

Incorrect. The C-A ERCW pump supplies flow to the A header. When the pump is stopped, flow to

both the 1A and 2A ERCW headers is decreased. This causes a decrease in flow through the seal

water heat exchangers. A reduction in flow to the 1A CCS heat exchanger will cause the A ESF

header to heat up as well as the Reactor Building and Miscella neous Equipment Headers to heat up.

The 1A CCP which would normally be in service would show an increase in oil temperature. The Seal

Water Heat Exchanger, supplied off the Miscellaneous Equipment Header would also heat up.

b.

Incorrect. Plausible, because oil temperat ure does rise, howeve r, Seal Water Return Heat Exchanger

temperatu re also rises.

c.

CORRECT. Seal Wate r Return Heat Exchanger temperatu re does rise, and CCP oil tempera ture

remains constan t.

d.

Incorrect. Plausible. since candidate incorrectly recalls cooling water supply to this component.

DISTRACTOR ANALYSIS

a.

Incorrect. Containment pressure is not high enough to cause the isolation and the sensor downstream

of the valve will not allow the valve to remain open with the pressure at 68psig , but plausible because

with the containment pressure above 1.5, a Phase A isolation would have occurred and many paths

would have isolated .

b.

Incorrect. Containment pressure is not high enough to cause the isolatio n, but since it is above 1.5,

then a Phase A isolation would have occurred and many paths would have isolated and the

downstream pressure is high enough to allow, but plausible because with the containment pressure

above 1.5 then a Phase A isolation would have occurred and many paths would have isolated and 78

psig is high enough for the downstream sensor to allow air to open the valve .

c.

Incorrect. Containment pressure is high enough to cause the isolation, but the pressur e sensed

downstream of the valve is not high enough to allow operating air pressu re to maintain the valve open

after the switch is placed in A-Auto, but plausible because with the containment pressure above 3.0 psig

then a Phase B isolation would have occurred causing isolation of the valve.

d.

CORR ECT. With containment pressure greater than 2.8 psig, a phase B isolation will automatica lly

occur, and the sensor downstre am of the isolation valve must detect greater than 75 psig to allow the

valve to remain open after the control switch was placed to the A-Auto position,

The short cycle valve, 1-FCV-2-35, modulates open to dump excessive condensate flow.

DISTRACTOR ANALYSIS

a.

Incorrect. The AFW pumps start on the loss of both MFPs and other conditions that are not described

in the stem of the question. Loss of one MFP at the stated power level starts the standb y MFP.

Further plausibility is added due to some Westinghouse plants are design ed this way.

b.

Incorrect. Suction pressure <20 psig causes the Condensate DI pumps to trip.

c.

CORRECT. Since MFW flow is greater than 40%, the condensa te inlet and outlet valves for the MFP

turbine condensers go closed.

d.

Incorrect. Plausible since a differential pressure is developed across a flow element (FE-2-35). This

L\\ P is converted to a flow signal which is used to control Short Cycle Valve (FCV-2-35) to ensure a

minimum of 5500 gpm condensate flow.

a,

Incorrect. Plausible, since power is greater than 10%. the P-10 blocks are active. This would prevent

an immediate reactor trip at the time of the failure, The SR Nls WOULD have to be manually

reinstated since the P-6 permissive requires both IR channels to be below the setpoint to automatically

Question:

Given the following plant conditions:

Following an accident , both Trains of Control Room Isolation have been initiated .

Several Auxiliary Building Area Radiation Monitors rise to the alarm setpoint.

Which ONE of the following MCR air intake radiation monitors will detect and alert the crew of a radiation

hazard entering the control room and what actions the ARI will direct the crew to perform ?

A.

0-RM-90-125,

Stop MCR Emergency Pressurization Fans.

B.

C.

0-RM-90-205,

Stop MCR Emergency Pressurization Fans.

D.

0-RM-90-205,

Align Emergency Pressurization Fan suction to alternate source.

DISTRACTOR ANALYSIS

a.

Incorrect. 0-RM-90-125 is in an isolated flow path due to the CRt. Plausible because the rad monitor is

the incorrect monitor. It would be in the flow path after the supply was realigned and stopping the fans

would be a way of stopping the intake of radiation.

b.

Incorrect. 0-RM-90-125 is in an isolated flow path due to the CRt. Plausib le because the rad monitor is

the incorrect monitor. It would be in the flow path after the supply was realigned and Annunciator 187-A

directs the action to align the Emergency Pressurization Fan suction to alternate source.

c.

Incorrect. 0-RM-90-205 will cause annunciator 187-A to alarm and the ARI directs the action to ALIGN

Emerge ncy Pressurization Fan suction to alternate source, not to stop the Emergency Pressurization

Fan. Plausible because the rad monitor is the correct monitor and stopping the fans would be a way of

stopping the intake of radiation.

d.

CORR ECT. O-RM-90-205 will cause annunciator 187-A to alarm. 0-RM-90-125 is in an isolated flow

path due to the CRI. Annunciator 187-A directs the action to align the Emergency Pressurization Fan

suction to alternate source.

C.

The OAC should obtain concurrence from another licensed RO prior to taking action.

D.

The OAC should immediately take appropriate actions necessary and inform the SRO when time

permits.

DISTRACTOR ANALYSIS

a.

Incorrect. Plausible, since under normal circumstances, the operator would stop a task in progress and

wait until a new procedure was written before taking any additional actions . The operator must stop

actions long enough to get approval from the SRO. The SRO would have to address the situation using

1OCFR50.54(x) criteria.

b.

CORRECT. The operator must stop actions long enough to get approval from the SRO. The SRO

would have to address the situation using 10CFR50.54(x) criteria.

c.

Questio n:

Given the following conditions:

Unit 1 is at 100% power. Solid State Protection System (SSPS) Train 'B' Actuation Logic testing is being

perform ed using 1-SI-99-1OB with:

Train 'B' SSPS Mode Selector switch in the 'TEST' positio n.

DISTRACTOR ANALYSIS

a.

Incorrect. The conditions stated in the stem result in a general warning on both trains of the SSPS

which causes the reactor trip and bypass breake rs to open (but no reactor first out annunc iator will be

lit). Thus the turbine trips as a result of the reactor trip. The four hour notification to NRC for a reactor

trip is correct. Plausible due to the notification time being correct and no other reactor trip first out

annunc iator will be lit except the turbine first out annun ciator.

b.

Incorrect. The conditions stated in the stem result in a general warnin g on both trains of the SSPS

which causes the reactor trip and bypass breakers to open (but no reactor first out annunciator will be

lit), thus the turbine trips as a result of the reactor tripping. The notification to NRC for a reactor trip is

a four hour notification , not an eight hour notification. Plausible due to the notification time being

correct and no other reactor trip first out annunciator lit except the turbine first out annunciator; and that

the notification time could be misapplied since the ESF actuation required time is 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> and an ESF

CORRECT. Since boron worth is greater at EOL, injection of RWST inventor y results in a higher

magnitude of change in reactor power. Per the appropriate references, Reactor Engineering records

the significance level of the reactivity event on the PER.

c.

Incorrect. Plausible if candidate confuses the change in boron worth with time in core life to be less,

With the plant at full power, and during the Shift Turnover for the 1900 shift, the Unit Supervisor is informed

of the following:

1-LS-63-50A (RWST Low Level) was declared inoperable at 1000 that day.

It was placed in the configuration required by Technical Specifications at 1400, and is expected to

remain inoperable until 2300.

A required surveillance instruction on 1-LS-63-51A (RWST Low Level) must be completed by 2330

today to preven t being out of frequenc y due to exceeding the NRC late date.

~_

A.

Functional. Even though two level switches are TRIPP ED and are inoperable, the remaining

operable level switches are sufficient for switchover to be functional.

B.

Functional. Even though two level switches are BYPASS ED, the remaining level switches are

sufficient for switchover to be functional.

C.

Not functional, because two level switches are TRIPPED and at least three level switches are

required for switchover to be functional.

D.

Not functional , because two level switches are BYPASSED, and at least three level switches are

required for switchover to be functional.

DISTRACTOR ANALYSIS

a.

Incorrect. Plausible, since there are other components in the plant that are placed to trip when

discovered inoperable. However, candidate fails to recognize that when one of these level switches

is inoperable, it is bypassed, not tripped. Further plausibili ty is added by the condit ions given; i.e.,

there TWO switches affected, and the remaining two are sufficient for actua tion capabi lity.

Incorrect. Candidate incorrect ly believes that these conditions require tripping of the two channels,

and uses that incorrect information to conclude that actuation capability is rendered not functional.

Plausible, since candidate may believe at least three channels are required to be operable at all

times, for Mode 1.

d.

Incorrect. Candidate correctly recognizes that these conditions require bypassing the two channels .

However, candidate fails to realize that this does not disable emergency coolan t recirculation

actuation capabilit y. Plausible, since some plant equipment requires at least three of four channels to

be operable; however, the candida te misapplie s that concept for these conditions .

A new release permit must be generated.

The same release perm it can be used following

independent verification of correct valve lineup.

A new release permit must be generated.

OISTRACTOR ANALYSIS

a.

Incorrect. The release permit would be violated because liquid released from the Monitor Tank was not

sampled and the same release permit cannot be used to continue the release . Plausible because the

release permit did sample the CDCT liquid intended to be released. and independent verification of the

valve line-up is something required if the rad monitor is inoperable.

b.

CORRECT. The release permit would be violated because liquid released from the Monitor Tank was

not sampled and a new release permit is required to continue the release due to the release being

terminated by a High Rad signal as identified in SOI-77 .01. The release permit did sample the CDCT

liquid intended to be released. and a new release permit is required in order to continue the release.

c.

Incorrect. The terminat ion of the release by the radiation monitor does not prevent a violation of the

permit. The release permit would be violated because liquid released from the Monitor Tank was not

sampled and the same release permit cannot be used to continue the release. Plausible because the

E-O, Reactor Trip or Safety Injection, would be used because AOI-27

is wrillen assuming no other accident is occurring.

DISTRACTOR ANALYSIS

a.

Incorrect. AO I-27 directs the closure of the MSIVs prior to leaving MCR and is wrillen to assume no

othe r accident is occurring. Plausible becaus e if the MSIVs were ope n, steam dump valve s would be

available and the AO I used for abando ning the MCR during an Appendix R fire is wrillen for assuming a

spurious SI occu rs. (The Appendix R AOI is the controlling procedure during Appendix R fire).

b.

Incorrect. AO I-27 directs the closure of the MSIVs prior to leaving MCR and is wrillen to assume no

other accident is occurring . If an accident is occu rring then the eme rgency procedure network would be

used . Plausible because if the MS IVs were open, steam dum p valves would be availa ble and the

Given the following:

The crew is performing FR-H.2, Steam Generator Overpressure, for an overpressure cond ition on

SG #2.

When the step is addressed to check affected SGs NR level it is noted that the SG #2 level is

A.

Continue in FR-H.2, but do not initiate any steam release until TSC evaluation is com plete.

B.

Continue in FR-H.2, steam release may conti nue until NR level indicates 100%.

evaluation is comp lete.

D.

Transition to FR-H.3, Steam Generator High Level, steam release may continue until NR level

indicates 100%.

DISTRACTOR ANALYSIS

a.

Incorrect. Plausible since the release of steam is prohib ited with a high level (> 93%) condition until

after a TSC evaluation is complete. Transition to FR-H.3 is directed from FR-H .2 at Step 3.

b.

Incorrect. The transit ion to FR-H.3 is required, howe ver candidate may corre ctly conclude that FR-H.3

is lower in priority on the FR-H status tree and not recall the transition. Plausible since even when NR

level indicates 100%, there is still significant volume before the steam gen erator fills with water.

c.

CORRECT. The RNO for the step directs the transition to FR-H.3 and FR-H.3 restr icts the release of

steam until a TSC evaluation is complete.

d.

Incorrect. The RNO for the step directs the transition to FR-H.3 and the release of steam is restricted

until a TSC evaluation is complete if the level exceed s 93%, therefore with the level at 100%, the

Quest ion:

Given the following:

Unit 1 experienced a Reactor Trip and Safety Injection .

The crew transitioned to FR-Z.1. High Containment Pressure, from E-1, Loss of Reactor or

Secondary Coolant.

While FR-Z.1 was being performed, the crew transitioned to FR-P.1. Pressurized Thermal

Shock.

The STA reports the containment pressure has dropped and the containment status tree is

GREEN and that no other RED or ORANGE paths exist.

Which ONE of the following identifies the basis of the FR-P.1 step for checking RCS pressure greater than

150 psig, and the proced ure the crew will implement if a transition is made from FR-P.1 during performance

of the step?

A.

To preclude the need to perform FR-P.1 action s, since pressurized thermal shock is not a serious

concern for a large-break LOCA;

Transition is made back to E-1.

B.

To preclude the need to perform FR-P.1 actions, since pressurized thermal shock is not a serious

concern for a large-break LOCA ;

Transition is made back to FR-Z.1.

C.

Transition is made back to E-1.

D.

To avoid delays caused by unnecessary soak periods required by FR-P.1.

Transition is made back to FR-Z.1.

DISTRACTOR ANALYSIS

a.

Incorrect. While a pressurized therma l shock is not a serious concern for a large-break LOCA , the

transition will be back to FR-Z.1, not to E-1. Plausible, since basis is correct, and with the FR-Z.1

status green the candidate could conclude the return to E-1 will be required.

b.

CORRECT. A pressurized thermal shock is not a serious concern for a large-break LOCA because

the system cannot repressurize with a large break LOCA. The step RNO will transition back to

instruction in effect, which is FR-Z.1 even though the status tree for it is now green .

c

Incorrect The bases is not to prevent the soak periods, but the transition to E-1 is correct. Plausible

because the procedure does contain modified Sl termination criteria and SI will be terminated in the

procedure which does reduce cooling to the core and the transit ion is correct

d.

Incorrect. The bases is not to prevent the soak periods, and the transition to FR-Z.1 is not correct.

Plausible because the procedure does contain modified SI termination criteria and SI will be

terminated in the procedure which does reduce cooling to the core and with the FR-Z.1 status green

Given the following:

Unit 1 was in Mode 2 with startup in progress when a loss of off-site power occurred.

The decision was made to place the plant in Mode 5.

The crew implemented ES-0.2, Natural Circulation Cooldown, and started cooling the plant down.

D.

Lower VCT pressu re;

Start the other 3 RCPs and immediately transition from ES-0.2 to GO-6 , Unit Shutdown From Hot

Standby To Cold Shutdown.

DISTRACTOR ANALYSIS

a.

Incorrect. Lowering the PRT pressure affects the #1 sealleakoff flow. but only if the leakoff flow path,

which is routed to the VCT. is isolated . Plausible because starting an RCP provides forced circulation,

and some spray flow correct and if ES-0.2 was continued until the end of the procedure. a transition to

GO-6 would be made .

b.

Incorrect.

Lowering the PRT pressure affects the #1 sealleakoff flow. but only if the leakoff flow path.

which is routed to the VCT, is isolated. Plausible because starting the other 3 RCPs and transitioning to

GO-6 after starting the RCPS is correct.

c.

Incorrect. Lowering the VCT pressure would allow increased sealleakoff flow. but ES-0.2 would not be

continued after the RCP was started (a transition would be made to GO-6 when the pump was started .)

Plausible because lowering the VCT pressure is correct and if ES-0.2 was continued until the end of the

D1STRACTOR ANALYSIS

a.

Incorrect. The PSA risk is Red (high) not Orange for the isolation of the ERCW header. Plausible,

since the action listed involves realignment of cooling water. The cooling water supply for the A train

DGs will not be affected as a result of isolating the strainer and no DG cooling water alignmen t would

be required.

b.

Incorrect. The PSA risk is Red (high) not Orange for the isolation of the ERCW header . Plausible,

since crosstie of the headers would be performed in accordance with AOI-1 3.

c.

Incorrect. Plausible, since PSA risk is correct, and the action listed involves realignment of cooling

water. The cooling water supply for the A train DGs will not be affected as a result of isolating the

strainer and no DG cooling water alignment would be required.

d.

CORRECT. The 2B ERCW header will be crosstied with the 1A ERCW header during performance of

AOI-13 and the PSA risk would be RED as identified in TI-124.

components of the RCS.

References:

LCO 3.4.9

Question:

Given the following plant conditions:

During a startup, the plant is in Mode 4.

GO-1, Appendix C, Mode 4-to-Mode 3 Review and Approval, has been comple ted up to the last

step, Operations Superintendent Hold Point, for granting appro val to enter Mode 3.

During scaffolding removal activities, a worker contacts the air line to 1-FCV-62-93, Charging Flow

Control Valve, resulting in pulling the air line loose from the valve operator, such that the air system

remains intact, due to crimping of the line on the air supply side of the break.

Which procedures will the Unit Supervisor use to respond to this event and the basis for taking quick action

to limit the effects?

A.

The Unit Supervisor will use AOI-10, Loss of Control Air to direct actions to prevent Pressurizer level

from exceeding 92% in order to maintain the presence of a steam bubble in the pressurizer.

B.

The Unit Supervisor will use AOI-10, Loss of Control Air, and direct actions to prevent the level

decrease to less than 17% to ensure subcooli ng margin can be maintai ned.

C.

The Unit Supervisor will use SOI-62.01, CVCS-Charging and Letdown and direct actions to prevent

the level decrease to less than 17% to ensure subcooling margin can be maintained.

D.

The Unit Supervisor will use SOI-62.01, CVCS-Ch arging and Letdown, to direct actions to prevent

Pressurizer level from exceeding 92% in order to maintain the presence of a steam bubble in the

pressurizer.

DISTRACTOR ANALYSIS

a.

Incorrect. Plausible, if a failed open charging flow control valve condition is not mitigated PZR level

would increase to the point where the desired steam bubble would not be maintained.

b.

Incorrect. Plausible since it contains the correct proced ure. Candidate incorrectly concludes that when

1-FCV-62-93, Charging Flow Control Valve, loses air it fails CLOSED. Using this incorrect conclusion,

it is logical to see why a candidate would then conclude that Pressurizer level will lower. Candidate

correctly recalls that there is a lower limit for Pressurizer level of 17%, and applies it to arrive at the

concern for losing all banks of Pressurizer heaters resulting in a potentia l loss of desired subcooling.

c.

Incorrect. Plausible since it contains a procedure with a title similar to the conditions given in the stem.

Candidate incorrectly concludes that when 1-FCV-6 2-93, Charging Flow Control Valve loses air it fails

CLOSED. Using this incorrect conclusion, it is logical to see why a candidate would then conclude that

Pressurizer level will lower. Candidate correctly recalls that there is a lower limit for Pressurizer level

of 17%, and applies it to arrive at the concern for losing all banks of Pressurizer heaters resulting in a

potential loss of desired subcooling.

d.

CORR ECT. When 1-FCV-62-93 loses operating air, it fails OPEN, resulting in significantly more

charging flow. If this is allowed to continue, Pressurizer level will exceed 92%, which could result PZR

level increasing to the point where the desired steam bubble would not be maintained.. SOI-62 .01

contains detailed action steps for isolating and bypassing 1-FCV-62-93, which will restore charging

flow control to the control room, even with the normal flow control valve failed open .

DISTRACTOR ANALYSIS

a.

Incorrect. Steam dumps are prevented from opening due to loss of vacuum . Therefore, no steam is

entering the condenser, and water box LlT will drop. The notifications required by SPP-3.5 are internal

only. Plausible if candida te fails to recall the condenser vacuum interlock with steam dump operation

but correctly identifies the required notifications .

b.

Incorrect. Steam dumps are prevented from opening due to loss of vacuum. Therefore, no steam is

entering the condenser and water box LlT will drop. The notification required by SPP- 3.5 are internal

only, no notification to the NRC is required . Plausible if candidate fails to recall the condenser vacuum

interlock with steam dump opera tion and incorrectly identifies the required notifications.

c.

CORR ECT. With a loss of condenser vacuum, steam dump operation is blocked. Therefore, no

steam is entering the condenser, resulting in a lower LlT across the condenser waterboxes . SPP-3.5

requires internal TVA notification be made due to the turbine trip.

d.

Incorrect. No steam is entering the condenser, resulting in a lower LlT across the condenser

waterboxes. The notification required by SPP-3.5 are internal only, no notification to the NRC is

required . Plausible because the waterbo x LlT response is correct and candidate may incorrectly

identify the required notifications .

DISTRACTOR ANALYSIS

a

CORRECT. Action Level 3, which is the most restrictive (requiring plant shutdown ), applies due to

RCS chloride exceeding 1500 ppb.

b.

Incorrect. Candidate incorrectly believes that Action Level 3 applies for SG chloride levels, when it is

distractor has plausibility because there is similar impact on plant operations if there were Action Level

2 conditions for RCS chloride.

d.

What is the effect of performing the source check portion of this test, and what is the SRO's responsibility for

Tech Spec/LCO Tracking Sheet entry?

A.

This will result in an automatic actuation of Train A of ABGTS . The SRO will make an entry on the

LCO Tracking Sheet that Train A of ABGTS is inoperable.

B.

RM-90-102 outpu t will be blocked during the source check, the SRO will make an entry on the LCO

D.

This will result in an automatic actuation of Train A of ABGTS . The SRO will make an entry on the

LCO Tracking Sheet that RM-90-102 is inoperable.

DISTRACTOR ANALYSIS

a.

Incorrect. Both parts are incorrect, but plausible, because of the close link between ABGTS (Auxiliary

Building Gas Treatment System ) operation and RM-90-102 (causes actuation of ABGTS). However,

candidate incorrectly believes that the COT causes an automatic actuation of ABGTS.

b.

Incorrect. Candidate correctly understands that the COT requires blocking of the outpu t of RM-90-102,

which prevents it from actuating ABGTS, and concludes therefore, that the associated train of ABGTS

is inoperable. This adds to the plausibility of this distractor, but it is incorrect, since a different LCO

(LCO 3.7.12) governs the operability of the ABGTS train itself.

c.

CORRE CT. This test requires blocking of the output of RM-90-102, which prevents it from auto

actuating the associated train of ABGTS . This is done on purpose, to prevent inadvertent/undesired

actuation of ABGTS . Further , this blocking renders the RM-90-102 inoperable.

d.

Incorrect. Candidate correctly concludes that this test renders RM-90-10 2 inoperable, but for the

wrong reason. It is plausible, since there are other components in the plant, that if running, or

actuated, are considered inoperable. However, candidate incorrectly believes that this test causes an

auto actuation of the associated train of ABGTS.

Unit 1 experiences a Safety Injection due to a steam generator tube rupture on SG #1.

All Reactor Coolant Pumps were removed from service due to loss of support systems.

RCS cooldown at maximum rate to target incore temperature is in progress.

The STA reports that a RED path for FR-P.1 , Pressurized Thermal Shock, exists on RCS Loop 1

on the FR-O, Status Trees.

Which ONE of the following identifies when the transition to FR-P.1should be made?

A.

Immediately transition to FR-P.1 from E-3 because FR-P.1 provides actions to limit cooldown and

repressurization of the RCS.

B.

Remain in E-3 until the cooldown is complete and then transition to FR-P.1 only if the RED path still

exists because the cooldown is needed to allow depressurization of the RCS.

C.

Remain in E-3 until the cooldown is complet e and then transition to FR-P.1 even if the RED path no

longer exists because the cooldow n is needed to allow depressurization of the RCS.

D.

Remain in E-3 until the safety injection is terminated, then transition to FR-P.1 only if the RED path still

exists because FR-P.1 provides actions to limit cooldown and repressurization of the RCS.

DISTRACTOR ANALYSIS

a.

Incorrect. Plausible, since the normal rules of usage would require implementation of FR-P.1 as soon

as the condition was confirmed to exist.

b.

Incorrect. Plausible since a stagnant loop condition will exist in the loop associated with the ruptured

SG with the RCPs off. CAUTION prior to the cooldown step in E-3 states that the anticipated red or

orange path on FR-P.1 does not require implem entation until after SI termination has been

accomplished.

c.

Incorrect. Plausible since a stagnant loop condition will exist in the loop associated with the ruptured

SG with the RCPs off. CAUTION prior to the cooldown step in E-3 states that the anticipated red or

orange path on FR-P.1 does not require implementation until after SI termination has been

accomplished.

d.

CORRECT. A stagnant loop condition will exist in the loop associated with the ruptured SG with the

RCPs off. CAUTION prior to the cooldown step in E-3 states that the anticipated red or orange path

on FR-P.1 does not require implementation until after SI termination has been accomplished. E-3

Note prior to Step 43 directs the operator to begin reevaluating for PTS/Cold Overpressure conditions.

An evaluation of PTS is delayed to this point since the active SI would contribute to the erroneous

red/orange path.
