LOIT Lesson Plans K&A: Knowledge of ac distribution system design feature(s) and/or interlock(s) which provide for the following: Interlocks between automatic bus transfer and breakersLearning Objective: Explain the operation of Switchgear NAN-S01 and NAN-S02 under normal operating conditions. REV 0 ES-401 Sample Written Examination Question Worksheet Form ES 401 - 5 PVNGS 2012 Reactor Operator NRC Exam Justification:The NAN-S01 and NAN-S02 buses are designed with the ability to allow a fast bus transfer from the unit auxiliary transformer source to the NAN-S03 and NAN-S04 source. The feature allows the 13.8 kV bus loads to remain energized in the event of a loss of the main generator, the normal in-house supply. If the main turbine/generator trips at 100% power, the reactor can remain critical following the load rejection as the reactor coolant pumps remain powered. The sequence of events and associated interlocks that

initiate a 13.8 kV NA fast bus transfer is listed below.In order to allow a NA fast bus transfer, the manual/auto transfer switch on the control room B01 panel must be in auto.The initiating event for a NA fast bus transfer is always a main generator trip . The activation of this lockout initiates the opening of the unit auxiliary transformer supply breakers, NAN-S01A and NAN-S02A.An automatic sync check is performed between the NAN-S01 to NAN-S03 and NAN-S02 to NAN-S04 bus. If the two sources are in sync, this contact is closed. Buses NAN-S03/S04 are checked for normal voltage and frequency. Both the unit auxiliary supply breaker and the bus tie breakers are checked for tripped 86 lockout relays. If both are reset, the close signal is allowed to pass on to the bus tie breakers, NAN-S03B/S04B. Correct: These 3 are required to have an automatic Fast Bus Transfer. A.Incorrect: 1 and 4 are correct but 6 is not. Lockout on the normal supply breaker would prevent the B.FBT from occurring. Candidate may believe a UAT Trip is required vice a Main Turbine Trip. Incorrect: 2 is correct, but 3 and 6 are not. Synch Check is automatically performed the C.synchroscope is not required for this check. Lockout on the normal supply breaker would prevent

the FBT from occurring. Incorrect: 4 is correct but 3 and 5 are not. Synch Check is automatically performed the D.synchroscope is not required for this check. UAT trip may be confused for the Main Turbine Trip

The

pressurizer can be vented remotely from the control room

through the following four paths (see UFSAR

Figure 18.II.B-1): 1. From the pressurizer vent through SOV HV-103, then through SOV HV-105 to the reactor drain tank (RDT). 2. From the pressurizer vent through SOV HV-103, then through SOV HV-106 directly to the containment

atmosphere. 3. From the pressurizer vent through SOVs HV-108 and HV-109, then through SOV HV-105 to the reactor drain

tank (RDT). 4. From the pressurizer vent through SOVs HV-108 and HV-109, then through SOV HV-106 directly to the

containment atmosphere. The RCGVS also includes the reactor head vent, which can be used along with the pressurizer vent to remotely vent gases

that could inhibit natural circulation core cooling during

post accident situations. However, this function does not

meet the criteria of 10 CFR 50.36(c)(2)(ii) to require a

Technical Specification LCO, and therefore the reactor head

vent is not included in these Technical Specifications. Pressurizer Vents B 3.4.12 BASES _______________________________________________________________________________ (continued) ________________________________________________________________________________ PALO VERDE UNITS 1,2,3 B 3.4.12-2 REVISION 34 APPLICABLE The requirement for the pressurizer vent path to be SAFETY ANALYSES OPERABLE is based on the steam generator tube rupture (SGTR) with loss of offsite power (SGTRLOP) and SGTR with loss of

offsite power and single failure (SGTRLOPSF) analysis, as

described in UFSAR 15.6.3 (Ref. 4). It is assumed that the

auxiliary pressurizer spray system (APSS) is not available

for this event. Instead, RCS depressurization is performed

by venting the RCS via a pressurizer vent path and throttling

HPSI flow. The analysis assumes venting to the containment

atmosphere via path 4 as described below. The results of the CENTS based analysis for SGTRLOP and SGTRLOPSF forwarded to the NRC in Reference 2 states that the

auxiliary spray was assumed to be unavailable and use of

pressurizer head vents was credited for de-pressurization.

The staff has reviewed and accepted the results of the

analysis. The staff's detailed evaluation has been reported

in Amendment No. 149, which increases power to 3990 MWt for

Unit 2 and incorporates replacement steam generator (Ref. 3). The pressurizer vent paths satisfy Criterion 3 of 10 CFR 50.36 (c)(2)(ii). _______________________________________________________________________________ LCO The LCO requires four pressurizer vent paths be OPERABLE. The four vent paths are: 1. From the pressurizer vent through SOV HV-103, then through SOV HV-105 to the reactor drain tank (RDT). 2. From the pressurizer vent through SOV HV-103, then through SOV HV-106 directly to the containment

atmosphere. 3. From the pressurizer vent through SOVs HV-108 and HV-109, then through SOV HV-105 to the reactor drain

tank (RDT). 4. From the pressurizer vent through SOVs HV-108 and HV-109, then through SOV HV-106 directly to the

containment atmosphere. Pressurizer Vents B 3.4.12 BASES ______________________________________________________________________________ (continued) _______________________________________________________________________________ PALO VERDE UNITS 1,2,3 B 3.4.12-3 REVISION 48 LCO A vent path is flow capability from the pressurizer to the (continued) RDT or from the pressurizer to containment atmosphere. Loss of any single valve in the pressurizer vent system will

cause two flow paths to become inoperable. A pressurizer

vent path is required to depressurize the RCS in a SGTR

design basis event which assumes LOP and APSS unavailable. ______________________________________________________________________________ APPLICABILITY In MODES 1, 2, 3, and MODE 4 with RCS pressure 385 psia the four pressurizer vent paths are required to be OPERABLE.

The safety analysis for the SGTR with LOP and a Single

Failure (loss of APSS) credits a pressurizer vent path to

reduce RCS pressure. In MODES 1, 2, 3, and MODE 4 with RCS pressure 385 psia the SGs are the primary means of heat removal in the RCS, until shutdown cooling can be initiated. In MODES 1, 2, 3, and MODE 4 with RCS pressure 385 psia, assuming the APSS is not available, the pressurizer vent paths are the

credited means to depressurize the RCS to Shutdown Cooling

System entry conditions. Further depressurization into MODE

5 requires use of the pressurizer vent paths. In MODE 5 with

the reactor vessel head in place, temperature requirements

of MODE 5 (< 210°F) ensure the RCS remains depressurized.

In MODE 6 the RCS is depressurized. ______________________________________________________________________________ ACTIONS A.1 If two or three pressurizer vent paths are inoperable, they must be restored to OPERABLE status. Loss of any single

valve in the pressurizer vent system will cause two flow

paths to become inoperable. Any vent path that provides

flow capability from the pressurizer to the RDT or to the

containment atmosphere, independent of which train is

powering the valves in the flow path, can be considered an

operable vent path. The Completion Time of 72 hours is

reasonable because there is at least one pressurizer vent

path that remains OPERABLE. Pressurizer Vents B 3.4.12 BASES _______________________________________________________________________________ (continued) ________________________________________________________________________________ PALO VERDE UNITS 1,2,3 B 3.4.12-4 REVISION 0 B.1 If all pressurizer vent paths are inoperable, then restore at least one pressurizer vent path to OPERABLE status. The

Completion Time of 6 hours is reasonable to allow time to

correct the situation, yet emphasize the importance of

restoring at least one pressurizer vent path. If at least

one pressurizer vent path is not restored to OPERABLE within

the Completion Time, then Action C is entered. C.1 If the required Actions, A and B, cannot be met within the associated Completion Times, the plant must be brought to a

MODE in which the requirement does not apply. To achieve

this status, the plant must be brought to at least MODE 3

within 6 hours, and to MODE 4 with RCS pressure < 385 psia

within 24 hours. The allowed Completion Times are

reasonable, based on operating experience, to reach the

required plant conditions from full power conditions in an

orderly manner without challenging plant systems. _______________________________________________________________________________ SURVEILLANCE SR 3.4.12.1 REQUIREMENTS SR 3.4.12.1 requires complete cycling of each pressurizer vent path valve. The vent valves must be cycled from the

control room to demonstrate their operability. Pressurizer

vent path valve cycling demonstrates its function. The

frequency of 18 months is based on a typical refueling cycle

and industry accepted practice. This surveillance test must

be performed in Mode 5 or Mode 6. SR 3.4.12.2 SR 3.4.12.2 requires verification of flow through each pressurizer vent path. Verification of pressurizer vent

path flow demonstrates its function. The frequency of

18 months is based on a typical refueling cycle and industry

accepted practice. This surveillance test must be performed

in Mode 5 or Mode 6. Pressurizer Vents B 3.4.12 BASES ______________________________________________________________________________ PALO VERDE UNITS 1,2,3 B 3.4.12-5 REVISION 31 REFERENCES 1.
