1.0 INTRODUCTION
The purpose of this document is to provide a description of the specific ATVS Mitigation System design proposed for implementation at the Byron and Braidwood Stations. The description is intended for the use of the Nuclear Regulatory Comission in evaluating the specific design for compliance to the ATVS rule of 10CFR 50.62(c)(1).

l February 1989 Rev. 6 2.0 ATWS HITIGATION SYSTEM DESIGN BASIS The Byrnn/Braidwood Stations ATWS Mitigatioa. te SAMS) design is based on the following requirements:
a.
The ATWS Rule (Reference 1) b.
ATVS Quality Assurance Requirements (Reference 2) c.
Westinghouse AMSAC Generic Design GJidance (Reference 3)
The foregoing documents provide the basis for the specific AMS system design as described in Section 3.0.

Februari 1989 Rev. 6 3.0 ATWS MIT!GATION SYSTEM FUNCTIONAL DESCRIPTION This section will functionally describe the proposed ATWS Mitigation System ( AMS) design for the Byron and Braidwood Stations. The operation of the proposed AMS is defined in Figure 3-1 and by the following descriptions.
3.1 ks_temOverview The required initiating actions of the AMS are as follows:
4 a.
initiate the auxiliary feedwater system, and b.
trip the main turbine.
The plant variable that is monitored to detemine loss of heat sink and provide for the actions described above is Steam Generator (SG) level.
Each steam generator is monitored by four existing sets of level instrumentation. Any of the four_ level measurements indicating low level is an indication of loss of heat sink f or that steam generator.
As shown in Figure 3-1, one AMS logic train with three logic subsystems is provided.
Both the main turbine trip and auxiliary feedwater actuation signals are initiated by this logic train.
For reliability, thrn redundant, identical logic subsystems are provided, and a two-out-of-three coincedence of the$e logic subsystems is required in initiate actuation.
3-1
- ~,. _
.. _ ~. _
February 1989 Rev. 6 Each AMS logic subsystem monitors the RPS Ch.1 SG 1evel transmitter frea each steam generator for a total of four level inputs. A three-out-of-four coincident logic scheme is employed to interrogate these SG level signals, therefore requiring three of the steam generators to indicate a loss of heat sint in order to actuate each subsystem. The AMS level setpoint will be 31 of narrow range span below the RPS Steam Generator level setpoint.
Two-out-of-three coincedence of the logic subsystem trips will actuate the auxiliary feedwater system (i.e., motor driven and diesel driven auxiliary feedwater pumps and related equipment) and trip the main turbine (through the emergency trip).
A time delay (approximately 25 seconds) is provided to ensure the reactor protection system will provide the first trip signal.
Arming of the AMS is automatic and is accomplished when both the C-20 power level (2 40% of nominal full power) permissives are achieved (see figure 3-1).
Upon a decrease in power below the C-20 power level the AMS will be automatically bypassed.
The C-20 power level permissive is developed in the AMS system b6 sed on turbine impulse chamber pressure.
Af ter an AMS initiation of the auxiliary feedwater system and
...ng of the main turbine, the AMS will self reset. That is, after AMS initiation as power decreases and af ter a time delay l
(approximately 360 seconds), the C-20 interlock will inhibit the logic thus allowing shutdown of the auxiliary feedwater system l

a Ff ruary 1989 Rev. 6 and reset of the main tur$fne trip. The time delay allows the MS to rem 6f n armed long enough to perform its function in the event of a turbine trip.
The logic pro +4 des for one inhibiting signal which is manually implemented under administrative control and prevents the logic from initiating its intended functions (i.e., start the auxiliary feedwater system and trip the main turbine).
This inhibiting signal results from the requirement that the MS must have the capability for testing daring power operation. When the operator selects the MS test /Dypass mode, the final MS actuation output devices (relays) are inhibited from operating and inadert sntly initiating the auxiliary feedwater system or tripping the main turoine dJring power operation.
Control nf the auxiliary feedwater system and main turbine are provided for by existing controls and are not in the scope of the MS design.
3.2 Main Control Room Interface The control room interface between the MS and the operator includes the following alarms and indications located at the main control boards:

- Inoperable alarm includes loss of power, module removed, and AMS in test /oypass.
3.3 Termination of Steam Generator Blowdown Steam generator blowdown will not be automatically terminated by the AMS.
Since the imediate effect of steam generator blowdown, in the event of an ATWS event, is to remove heat from the steam generator, automatic isolation is not necessary. Once AMS is initiated, steam generator inventory can be adequately satisfied with both trains of auxiliary feedwater operating. Auxiliary feedwater flow per steam generator will De approximately 320 gpm with maximum blowdown flow per steam generator of 90 gpm.

e FeDruary 1989 Rev. 6 4.0 PLAq iPECIFIC DESIGN DETAILS The following section provides the plant specific design details as requestec by the NRC. Each topic is addressed in the order in which they are listed in Reference 4.
4.1 Diversity The ATWS Hitigation System ( AMS) design for the Byron and Braidwood Stati(ns uses equipment which is largely diverse from that used in the Reactor Protection System (RPS). AMS inputs are derived from the existing SG 1evel and C-20 instrumentation which is located in the RPS Westinghouse 7300 protection cabii As.
The AMS SG level and C-20 inputs are isolated from the existing instrumentation loop signals Dy Technology for Energy (TEC)
Analog Si nal Isolators.
These isolators are classified as safety related. Af ter isolation the signals are fed to SAIC (Science Applications International Corporation) Distable units which generate the SG low level and C-20 loge inputs to the SAIC Solid State Logic System. The Solid State Logic System provides imp'ementation of the coincidence logic, pertnissives, test-inhibits, time delays and other AMS functions. Outputs frorr the logic system are then used to trip the turbine and start auxiliary feedwater via a number of interposing relays. The interposing relays interlocking safety related circuits are classified as safety related.
These relays will be Struthers Dunn relays.
4-1
Tebruary 1989 Rev. 6 Major comoonents of the AMS are therefore provided by manufacturers who are diverse from those used in the Westinghouse 7300 protection cabinets and Westinghouse solid state logic cabinets.
4.2 Logic Power Supplies The AMS logic will De powered through a non-safety related 24 VDC uninterruptable power supply (UPS) purchased from Lambda j
Electronics specifically to power tM AMS cabinet. This UPS will have a current limit of 5.7 amps.
Normal power to this UPS will De from a 120 VAC, non-safety related, and non-battery backed bus.
A 15 amp breaker in the distributic, anel will limit the maximum current available at the AMS cabinet, UPS input.
Inside of the AMS cabinet, the UPS power supply and its 120 VAC input power will De isolated by distance and barriers from the rest of the cabinet equipment.
Thus the maximum credible fault of the power supply and its associated cables would be limited to its 5.7 amp at 24 vde output.
The guidelines in 10CFR50.62 ( ATWS Rule) state that:
The AMS power supply is not required to be safety-related.
The AMS must be capaDie of performing its safety-related function foilowing a 1oss of of fsite power.
The AMS logic power must be independent from the power supply for the Reactor Trip System, 4-2
February 1989 Rev. 6 The AMS logic power must be independent from the power supply for the Reactor Trip System.
A new UPS, as the AMS power supply, complies with the guidelines in 10CFR50.62 as discussed below:
q a.
Safety Classification of AMS Power Supply The new UPS shall De non-safety related.
l b.
Operation Following loss of Offsite Power Since the AMS cabinet is powered from an ur.interruptable de source (i.e., internal batteries and voltage regulator),
the system is capable of performing its function following a loss of offsite power.
Power will be available for at least one hour after a loss of all AC power.
c.
Independence From Reactor Trip System Power Supply Since the AMS Cabinet will be powered from a new UPS, with its own battery charger, the AMS logic power supply is totally independent from the Reactor Trip System power supply.

February - 1389-Rev. 6 4.3 Safety-Related Interface Two safety-related interfaces exist between the AMS and existing safety related circuits. The first is the
. interface between the AMS and the SG 1evel and C-20 instrumentation circuits. As previously discussed in Subsection 4.1, analog signal isolation is provided by-the.
use of Technology for Energy Corporation analog signal isolators. The second is the interface between the AMS and the auxiliary feedwater circuits.
Isolation is provided by the use of Struthers Dunn relays. The existing criteria-for physical separation between reactor protection, ESF, and non-safety system wiring _will also be utilized.
- 4.4 Quality Assurance
. Safety-related components which are part of the AMS will De i
procured with the appropriate quality assurance-required =

' for safety-related equipment. All other_ components in the AMS design will be procured using the quality assurance l~
requirements stated in Generic Letter 85-06 (Reference 2).
ll l
- All activities _ involved in -the construction, maintenance L
and operation of _the AMS will De in accordance with the eighteen items of the above referenced generic letter and other Connonwealth Edison Company quality control requirements.
l 4-4
. ~ - -
FeDruary 1989 Rev. 6 4.5 Maintenance Bypasses Maintenance at power can be accomplished by taking the AMS out of service administratively (main test / bypass switch) and removing electrical power.
It is recomended that the main test / bypass switch located in the AMS cabinet, be
]
placed in the test / bypass mode to ensure that maintenance activities do not result in spurious actuation of the AMS output relays.
Loss of power to the AMS or placing the AMS in test mode will result in an AMS inoperable main control al arm. This alarm along with other AMS alarms and indicating lights will be grouped and located on the main control board utilizing human factors engineering prac ti ces.
4.6 Operating Bypasses ine AMS shall De automatically armed coincident with power above C-20 (40% of nominal full power) as a permissive.
Bypass of the AMS shall De automatically initiated if the power is reduced below C-20.
The C-20 power level is measured by two transmitters. The transmitters will measure first stage impulse chamber pressure at the high pressure turbine.
The basis for the 40% of full power l
setpoint is provided in 0/G-87-10 (Ref. 5). The automatic Dypass of the AMS is indicated in the control room via an l

-Box.
4.7 Means for Bypassing The main test / bypass switch as discussed in Sections -3.1 and 4.5 is a permanently installed toggle switch with two positions:
normal and test /oypass. The main test /0ypass switch is located in the MS cabinet and is the only means provided for oypassing -the entire system. An operating bypass switch is provided to allow bypassing of any one bistable during system operation. This allows on-line testing and calibration of the analog instrument-loops without degrading system operacion or reliability. Other means for bypassing as specifically excluded by the guidance are not used.- The main test / bypass switch will De included in the overall human factors engineering review of the system.
4.8 Manual' Initiation 1
Manual actuation of the AMS is not provided. Manual initiation of auxiliary feedwater and manual tripping of the turbine can be accomplished by the operator at existing controls provided on the main control boards.

4.9 Electrical Independence From Existing Reactor Protection System And Other Safety Related Circuits The interface between the SG 1evel and C-20 instrumentation loops and the AMS is made through Technology for-Energy Corporation (TEC) Model 156 Nuclear Qualified Analog Isolators. These isolators, which are located in a mild environment, have been fully qualified by the vendor according to the guidelines set forth in the applicable IEEE Standards. The maximum credible voltage / current transient which the non-safety-related (output) side of the circuits would be exposed to is approximately 30 volts DC and 10 amps due to the current limiting voltage regulator installed on the output of the UPS power supply circuit and due to the distance and barrier isolation of the 120 vac UPC input power.
Appendix A of AMSAC Generic SER criteria has been satisfied by the TEC Model 156 isolator as-follows:
A)- Attachment 1 of this document are diagrams which show how the maximum credible transients were-applied during the TEC testing. These diagrams also include short, ground, and open testing.
B) The TEC Model 156 isolator has been tested to demonstrate that the isolator would provide isolation during maximum credible transient of 120VAC at 20 amps 4-7

f February 1989 Rev. 6 and 2000VDC at 20 mA and dJring other transients'such as shorts, opens, and grounds. This testing is documented in TEC Reports 156-TR-02 and 156-TR-03.
These tests envelope any credible voltage and current levels present in the AMS cabinet.
C) See Item B above.
0)L The pass / fail acceptance criteria for the TEC isolator will be that the isolation capaci11ty of the assembly is not degraded during or after the transient.
E)- The TEC isola +, ors were tested to IEEE 323-1974 and 344-l 1975 as documented in TEC Reports 156-TR-02 and 156-TR-03.
This environmental and seismic testing envelopes the Byron /Braidwood station requirements for the installed location.
F). -The TEC isolator has been successfully tested to-determine susceptibility, at 10V/M from 20-50 MHZ and l
15 V/M from 100-500 MHZ with a spot check from 500 to 1000-HZ. The stainless steel case will also De grounded.which generally eliminates electromagnetic interferences.

s-February 1989 Rev. 6 The design of the' isolators is based on an inherently fail-safe principle which ensures isolation, even if all power is removed from the device.
It should be noted that the TEC isolators are protected by both in-line circuit fuses and internal fuses on the isolator outputs.
The AMS output interface to the safety related auxiliary feedwater circuits is provided at the output rr. lays via coil ~ to contact separation. The proposed out>ut relays are Struthers Dunn auxiliary relay Type 219. Thes e relays, which are located-in-a mild environment, will De certified to operate in the environment in which they are located.
The results of the seismic testing, already performed, envelope the Byron /Braidwood Stations requirements.
In-addition, the relays have been functionally tested. The
- maximum credible voltage and current transient which the non-safety-related side of the-circuits would be exposed to is approximately-30 volts de at 10 amps (i.e., tne AMS -
caDinets where the relays-are located, are powered from a
- 24 volt DC System which is current limited to 5.7 amps).

envelope the maximum expected credible voltage and current levels present in the AMS cabinets.
The relays are rated 10 amps non-in4uc'Jve and 3 amps inductive at 120VAC. The re'iays are rated 3 amps non-inductive and 1 amp inductive at 125YDC. The relays are inherently fail-safe because power is not required for the relays to function as isolation d* vices. Typically electromagnetic interference is not a problem with relays.
Mor' -detailed documentation addressing aualification and testing is available in the Westinghouse offices.
4.10 Physical Separation From Existing Reactor Protection System The AMS hardware is located in its own cabinet which is separate from the existing reactor protection system cabinets. Actual isolation of the SG 1evel, C-20, and aux-feedwater circuits will be done in the AMS cabinet.
Isolators, safety related relays and wiring within the AMS ceDinet will be physically separated to meet all existing 4-10

separation requirements. Likewise all existing criteria for physical separation of re'ai: tor protection, ESF, and non-safety system wiring external to the AMS cabinet will also be followed.
4.11 Environmental Qualification The AMS caDinet is located in a mild environment. The environmental parameters for the location, Zone A1, are-o listed in the Byron /Braidwood FSAR Table 3.11-2.

Isolation devices shall be provided with seismic qualification in accordance with the basis for plant licensing.
4.12 Testability at Power The AMS is designed to allow testing of the bistable units, solid state and relay logic system, and final AMS output relays during power operation as well as below the C-20 power level permissive. AMS testing at power will be performed once every 6 months. AMS testing at power is subdivided into three areas which are described individually below.
a.
Testing of bistable units - The logic train requires six bistables (one per steam generator plus two C-20's) which are housed in three dual bistable modules mounted in the logic subrack assembly.
An Operating Bypass selector switch on the test panel will allow the testing of any one bistable at a time.
Selection of a bistable with this switch will introduce a selectable logic tripped or not tripped signal to the logic system regardless of bistable state. Thus, calibration or test of that Distable can be 4-12
l i
s-February 1989 Rev. 6 accomplished without introducing a f alse trip signal into the logic system. The bypassing of this bistable will be alamed in the control room and indicated locally. Test points on each bistable front panel allows monitoring of the process variable voltage, the setpoint voltage and the reference voltage.
b.
Testing of system logic (solid state and relay) - Since the bistables are tested individually, it is not possible to force more than one bistable into a trip status simultaneously f rom the Operating Bypass switch. To artificially initiate the system logic for testing, external logic test input test switches are provided for each bistable output.
3 The six logic test input switches art cly functional if the master test / bypass switch is in the test / bypass.
posi ti on. This position of the mastei test / bypass switch is alamed via the AMS inoperable alarm in the control room, is indicated via status light in the control room, and is indicated locally.
4-13
f t
i-February 1989 Rev. 6 Each logic test input switch is a three position toggle with each position accomplishing the following respective function:
Logic Test Input Swi tch Position Function Norm Allows the bistaDie output to directly operate the logic system Test-Trip Disconnects the bistable output f rom the logic and forces a logic "1" creating an artificial " trip si tua ti on."
Test-Norm Disconnects the bistable output f rom the logic and forces a logic "0" creating an artificial "non-trip or
=
normal situation."
Each logic test input switch will be used to simulate Distable inputs to the three logic subsystems. When the proper combination of 3 out of 4 steam generator level trips and the 2 reactor power trips are simulated, then the three logic subsystems will trip and that will result in AMS SG 1evel pretrip and AMS anned local indicating lights being lit. Af ter the appropriate time delay an output tripped light will

4-14
w a
February 1989 Rev. 6 An individual logic bypass switch is provided for each of the three logic ="bsystems. When the master test / bypass switch i3 in the test / bypass position, these individual logic bypass switches will force the associated logic subsystem output to the "untripped" state regardless of logic inputs. This feature allows testing of the 2 out of 3 logic functions.
c.
Testing of final AMS output relays - The testing circuits used for the final AMS output. relays and final actuated devices at power will De similar to the testing schemes used in the Byron /Braidwood Safeguards Test Cabinets.
However, for the purpose of the AMS, testing of the final AMS output relays and final actuated devices will be limited to a continuity test only of the circuits and not full actuation of the final devices (control relay which operates the auxiliary feedwater pump, for example).
Continuity testing of the circuits will De used
- because, the AMS is not safety-related, any additional periodic cycling of safety related system components in the auxiliary feedwater system l
as a result of AMS testing should be limited in order to maximize the qualified life of those components, and l

- i tripping _of the turbine at power is obviously unacceptable.
A complete off-line end to end test will be performed once each refueling outage.- This test will simulate inputs to transmitters and monitor proper actuation of output relays.
A test procedure will be prepared once the system hardware is purchased.
4.13 Completion of Mitigative Action Once initiated tb AMS actuation-signal will go to completion except as delayed by the 25 second time delay.
The C-20 permissive is delayed 'from de-energizing for 360 seconds ao ensure that the C-20 permissive is present so that AMS operates.
