JP E-L-83-4 Rev. 1 Page 3 of 66 ABSTRACT The St; Lucie Plant Unit No.
2 is provided with an Auxiliary Feedwater Actuation System (AFAS) designed to automatically actuate Auxiliary Feedwater System (AFW) components.
The AFAS.is actuated by Steam Generator low leveL Steam Generator and Feedwater header pressure inputs to AFAS are used to identify and isolate flow to a ruptured steam generator.
The current Technical Specifications require a semi-annual surveillance test of the AFAS automatic actuation logic, including the subgroup relays which control individual AFW components.
This analysis compares the change in AFAS availability resulting from an extension of this test interval to 18 months (refueling outage interval).
The results indicate an insensitivity of AFAS availability to this change.
If the AFAS is assumed not to be demanded during the test interval, the availability decreases from 0.9975 to 0.9953.
Anticipated transients, such as Loss of Main Feedwater, are expected to result in about 3 demands on AFAS per reactor year.
When these expected demands are included as effective system
- tests, the availability change resulting from the test interval extension is from 0.9982 to 0.9980.

JPE-L-83-4 Rev. 1 Page 7 of 66 INTRODUCTION The St.
Lucie Unit 2 Technical Specifications require the testing of the automatic actuation logic portion of the Auxiliary Feedwater Actuation System (AFAS). This includes de-energization of the subgroup relays which actuate Auxiliary Feedwater System pumps and valves.
This analysis examines the sensitivity of AFAS availability to the frequency of this test.
A fault tree of the AFAS was constructed, solved and quantified with the time between tests incorporated as a variable.
System availability was calculated for various test intervals.
The effect of including the expected operational demands on AFAS as system "tests" is also examined.
JP E-L"83-4 Rev. 1 Page 8 of 66 II.
AFAS S YSTEM DESCRIPTION The Auxiliary Feedwater Actuation System (AFAS) was designed by Combustion Engineering (CE).
The AFAS logic and hardware arrangement is similar to the CE Reactor Protection System.
A complete description of the AFAS appears in Section 7.3 of the St. Lucie Unit 2 Final Safety Analysis Report.
Figure 1 shows a simplified functional diagram of the AFAS and a brief description of the various subsystems is given below:
1)
Measurement Channels The AFAS receives, as input, signals from Steam Generator A and B level, pressure and Feedwater Header A and B pressure.
Four measurement channels are provided.
Any two channels providing a coincident trip signal will actuate AFAS.
The system is designed to allow the bypass of one channel and may be operated in a two-out-of-three logic configuration.
Figures 2, 3 and 4 show the measurement channel instrument loops.
2)
Steam Generator Rupture Logic Normally, a low-level condition in the Steam Generators will cause AFAS to actuate Auxiliary Feedwater (AFW) components to direct flow to the generators.
If a steam or feedline break
- exists, differential steam generator or feedwater header pressure willcause AFAS to isolate flow to the faulted generator.
Bistable device outputs are arranged to identify the ruptured generator.
Figure 5 shows a typical channel and Figure 6 develops the bistable relay contacts in the steam generator rupture logic. AFAS-1 actuates AFW components which provide (or prevent) flow to Steam Generator A, AFAS-2 controls flow to Generator B.
3)
Logic Matrices The bistable relay contacts are combined into 6 "AND" gates which represent all possible combinations of 2 of 4 channel inputs (AB, AC, AD, BC, BD, CD).
Each 2 of 4 logic matrix demnergizes four matrix relays which provide signals to the matrix ladders.
Figure 7 shows the AB logic matrix including the channel bypass circuitry.
Figure 8 shows the bypass switches and relays.
Note that the switch contacts are connected so as to allow bypass of only one channel at a time. A typical bistable/matrix relay and its transistor driver is shown on Figure 9.
4)
. Matrix Ladder
. Contacts of the matrix relays are arranged in series to form a six-input
."OR" gate (Figure 10).
Any open contact will de~nergize this path and provide a signal to its associated trip delay.
When the trip delay times out, the trip delay relay d~nergizes, which, in turn, d~nergizes four AFAS initiation relays (Figure 11).
JP E-L-83-4 Rev. 1 Page 9 of 66 6)
Actuation Logic The initiation relay contacts are combined in a "selective" 2 of 3 logic.
Coincident signals from matrix ladder combinations AB, AD, CB and CD will demnergize two, interposing relays.
This removes power from the subgroup actuation relays which control AFW components.
Of the ten actuation relays per channel, five,are latching and five are cycling.
When steam generator level increases to a given setpoint, the cycling relays will re-energize, closing AFW pump discharge valves to prevent overfilling a steam generator and/or allowing restoration of main feedwater.
The latching relays control AFW pumps and remain dern'nergized until AFAS is reset.
Figure 12 shows the actuation circuitry and Figure 13 a typical actuation relay.
Power Supply I
The four AFAS channels are powered from four 120 VAC Measurement Buses.
The bistables, bistable
- relays, matrix relays, initiation relays, interposing and actuation relays are energized by 12 VDC power supplies.
Figure 14 is a block diagram of the "A"channel power supplies.
The AFAS design allows testing of all portions of the
- system, including starting/cycling of AFW components.
The subsystem testing (as required by Technical Specifications) proceeds as follows:
Sensor Check 2) 3)
Every shift, the measurement channel outputs are checked against other channels and against their "as left" parameter values.
Bistable Trip Units A test signal is applied to the bistable input and varied until the trip action is noted.
Demnergization of the bistable relays is verified.
Logic Matrix Each 2 of 2 logic matrix (AB, AC, AD, BC, BD, and CD) is tested as well as the matrix relays and matrix ladders.
The test circuit makes use of double coiled (primary and secondary test) bistable and matrix relays.
With the matrix relay test coils energized, the matrix relay contacts will not dropout upon deenergization of the primary coil.
The bistable relay test coils are wired so that upon energization, their magnetic field opposes the primary coils and the bistable relay contacts drop out.
This arrangement allows testing the logic matrices and the matrix relay primary coils
~ without AFAS actuation.
A Matrix Relay Select Switch then allows the individual deenergization of the matrix relay test coils and, hence, dropout of the associated matrix relay contacts.
The matrix ladders are individually tested in this way, again, without AFAS actuation.
JP E-L"83-4 Rev. 1 Page 10 of 66 4)
Actuation Logic The AFAS test circuit allows de-energization of one initiation relay at a time. This opens one current leg of the selective 2 of 3 logic and loss of current is verified.
5)
Actuation (Subgroup) Relays Individual actuation relays may be demnergized to actuate the associated AFW component.
6)
Actuation Relay Group Test The actuation relay group is held energized by a test bus.
The lockout relays are d~nergized.
This verifies that there are no "sneak" circuits which willprevent demnergizing of the relay group.
A listing of the components actuated by AFAS is provided as Table 1.
JP E-L-83-4 Rev. 1 Page 11 of 66 III.
APAS FAULTTREE The primary purpose of testing standby systems such as AFAS is to ensure the probability that the system will fail to operate when demanded (system unavailability) is maintained acceptably low.
To predict the effect of test frequency on AFAS a
model is developed which calculates the system unavailability as a function of the system's components'navailabilities..Por the AFAS, the modelling methodology chosen was the fault tree approach.
The APAS fault tree appears as Pigure 16 with the fault tree discussion below.
The APAS system boundary was chosen in accordance with Regulatory Guide 1.22 definitions of protection system and actuation device.
Since APAS actuates a number of components, the modelling decision was made to consider the actuation path to one typical component.
Thus, the APAS availability calculated elsewhere in this report is the availability of AFAS to actuate a
single component.
The actuation device chosen is the circuit breaker for AFW motor-driven pump 2A.
Faults were developed to the component level for the pump circuit breaker, control circuit (Pigure 15), AFAS components and measurement channel instrument loops.
General assumptions made to guide the fault tree development appear below:
1)
Primary faults considered were open and short circuits of various APAS components.
2)
Only automatic actuation of AFAS was considered.
No credit for manual actuation locally (AFAS cabinets) or remotely (control room panel RTGB-202) was taken.
3)
Loss of 125 VDC control power to the circuit breaker control circuit was not developed or quantified.
, 4)
Test and maintenance contributions to AFAS unavailability were not considered.
That is, the contribution due to a
component's being unavailable because of a
test or due to scheduled or unscheduled maintenance is not included.
5), Common cause failures were not included in the fault tree.
Discussion of potential common cause failures appears in Section VIIof this r eport.
6)
A low level condition is assumed to exist in Steam Generator A. Neither steam generator is assumed to be ruptured.
7)
Four measurement channels are assumed operable.
No channel is in bypass.
8)
A coil short to power is the only fault considered for the Steam Generator rupture relay (Figure 6).
Faults leading to spurious actuation of the Steam Generator or Feedwater header differential pressure bistable were not modeled.
Assumptions 2, 3, 4 and 5 are conservative for this analysis.
By not including these contributions, the system unavailability is underestimated.
However, this tends to increase the importance of the actuation relays to AFAS unavailability.
Since the sensitivity of AFAS to actuation relay test frequency is the parameter of concern, these assumptions are conservative.

BASIC EVENT PROBABILITIES The basic events of the AFAS fault tree were identified and probability values calculated.
The AFAS components are in standby during reactor power operations.
For these components an average unavailability may be calculated by:
where Q = Unavailability (average) h = Component Failure Rate T = Fault Exposure Time and the fault exposure time is one-half the time between tests.
Failure rates were obtained primarily from the Interim, Reliability Evaluation Program (IREP) data base.
The "Parts Count"
- method, as described by Reference F, was used to estimate the failure rate of components for which data was not unavailable.
Test intervals were obtained from the St. Lucie Unit 02 Technical Specifications.
For the components tested under the automatic actuation logic surveillance requirement, the fault exposure time was left as a variable.
Table 2 lists the AFAS fault tree basic events and the component unavailability calculations.
JPE-L-83-4 Rev. 1 Page 13 of 66 V.
AFAS UNAVAILABILITYCALCULATION The AFAS fault tree was solved for minimal cutsets and the component unavailabilities substituted for the basic events.
This results in the following expression for the fault tree top event probability:
QAFAS = 1.4E-3+ 4.2E-7 x T
+ 5.1 E-12 x T2 where QAFAS = Failure of AFW Pump 2A Circuit Breaker to close automatically upon Steam Generator 2A Low-Level T = k (Time between Automatic Actuation Logic Tests)
In the fault tree solution, the following approximations were made:
1)
Cutsets up to order 3 were retained.
Higher order cutsets were truncated.
2)
The measurement channel components were grouped into a
"super-component".
The cutsets obtained were therefore simply the combinations of three of four channels failing which results in system failure.
Since common cause failures were not quantified, these probabilities were negligible contributions to system unavailability.
JP E-L-83"4
. Rev. 1 Page 14 of 66 VI AFAS SENSITIVITYTO SURVEILLANCEFREQUENCY The equation developed in the preceding section is used to estimate AFAS availability as a function of time between tests.
Two cases were evaluated.
Table 3 lists AFAS availability for various test intervals assuming there are no demands on AFAS arising from plant transients.
This is conservative in that a number of anticipated plant transients will place a demand on the Auxiliary Feedwater System
- and, hence, on AFAS.
Prom Reference G, the transients expected to result in an APAS demand were identified as well as their mean occurrence frequency.
Table 5
summarizes this information.
The APAS availabilities are recalculated in Table 4 by assuming that the operational demands on AFAS are effective system tests and that the surveillance required by Technical Specifications is an additional system test.
Table 4 calculations also assume that failures of the AFAS when demanded are identified and corrected.
The results indicate a relative insensitivity of AFAS to changes in test intervaL Without considering the operational demands on AFAS (Table 3) a 20096 increase in test interval (6 months to 18 months) results in a decrease in calculated AFAS availability from 0.9975 to 0.9953.
When the effect of the expected frequency of demands on AFAS is considered (Table 4), the same increase in test interval results in calculated availability decreasing from 0.9982 to 0.9980.
JPE-L-83-4 Rev. 1 Page 15 of 66 VIL COMMON CAUSE CONSIDERATIONS The preceding section shows that AFAS availability is not significantly affected by changes in test intervaL The fault tree analysis assumes, however, that the component failures identified (basic events) are independent.
This. section consideres common cause failures among the actuation logic components.
Of particular concern are the actuation (subgroup) relays since all the remaining AFAS subsystems may be tested without actuating plant equipment.
The discussion below identifies the potential common causes of multiple actuation relay failure and the mitigating design or operational factors:
1)
Manufacturer/Design The actuation relays are all supplied by Electro-Mechanics, Inc. of New Britain, Connecticut.
They are open, medium duty, general purpose relays.
A review of design specifications indicates that these relays are adequate for their DC and AC load switching applications.
2)
Environmental (Temperature, Humidity, Moisture, Radiation, Pressure)
The AFAS cabinets are located in the Control Room and are not subject to environmental extremes.
The maximum heat load within an AFAS bay is about 500 watts.
There are two fans on the bottom of each bay ('A, B, C, and D) for cooling.
An "AFAS Trouble" alarm is provided for loss of bay cooling.
3)
Out of Tolerance Voltage, Voltage Spikes - The bistable power supplies, which maintain the actuation relays energized, are provided with fault protection circuitry.
The relays are pr otected against overvoltage conditions by this circuitry and, in addition, they are designed to withstand short voltage spikes.
The relay contacts which form the actuation path in AFW component control circuits are normally open and close to actuate the component.
Thus, a postulated surge in the control circuit would not be expected to affect the AFAS actuating path.
3)
Corrosion - The actuation relay contacts are silver cadmium oxide. This, combined with the mild enviromental conditions, minimizes the possibility of normally open contacts developing an electrically resistive oxide layer.
5)
Maintenance - The relays are protected by a clear shield in the AFAS bays.
This protects the relays against damage while performing maintenance on other AFAS components.
The only expected maintenance on the actuation relays is replacement upon failure.
Based on available failure data, the
-relays are not expected to fail frequently.
This, coupled with post-
- maintenance testing of the system minimizes the possibility of common-cause maintenance induced failures.
6)
Dust, Dirt - The control room HVAC system includes filters to remove
.. particulate matter from the chilled air. Periodic maintenance of the AFAS willreveal any abnormal build up of dirt on the actuation relays.
JPE-L-83-4 Rev. 1 Page 16 of 66 VIII. CONCLUSION The discussion supra shows that, by extending the AFAS actuation logic test
- interval, no significant change in AFAS availability occurs.
Based on the calculations of section 6,
an increase in test interval from 6 to 18.months (refueling outage interval) decreases AFAS availability from 0.9975 to 0.9953.
When the expected number of operational demands on AFAS is included, the availability decrease is from 0.9982 to 0.9980.
The AFAS design, operation and maintenance also minimizes the possibility of credible common causes of multiple failures.
