- 3. FSAR REFERENCES 3.1 Chapter 6 3.2 Chapter 7, Section 7.3
3.3 Other
Logic Drawing 25203-28150, Sh. 1-4
- 4. PLANT OPERATING REQUIREMENTS 4.1 The system functions are implemented by means of redundant sensors, instrument loops, logic and actuation devices.
-Independence is provided between redundant elements to preclude
( any interactions between channels during maintenance or in the event of channel malfunction. Redundant elements are electrically isolated from each other such that events affecting one element are not reflected in any other element. 4.2 The Engineered Safety Actuation System detects incident conditions t and initiates the safety features systems which are designed to localize, control, mitigate, and terminate such incidents. The Engineered Safety Features Actuation System is divided into four sensor channels (A, B, C, and D), two actuation channels, and two logic channels for sequentially loading the emergency l generators.
- 4.3 All process variables are transmitted as analog signals. Loss of voltage on the 4.16kV emergency bus is detected by potential transformers and bistables.
4.4 Four essential or vital power sources are provided for the ESAS. Two emergency diesel generators are provided to supply power to the actuated equipment of the protective systems in
- (, case of loss of offsite power.
-~
OP 2384 Page 3 Rev. 2 b . 4. 5 If offsite power is available, the safeguards equipment starts directly. If offsite power is not available, load shedding and sequencing are required for sequential loading of the diesel generators. , 4.6 Each actuation channel (1 or 2) of each of the following actuation signals can be initiated by'a pushbutton located on the main control board: SIAS, CSAS, CIAS, EBFAS, SRAS, MSI, and AEAS. Each pushbutton initiates all actuation groups of the associated signal within its respective actuation channel.
- 5. PREREQUISITES 5.1 120 VAC power is available through vital AC panels:
VIAC-1 (VA 10) Circuit Breaker 14 VIAC-1 (VA 10) Circuit Breaker 18 VIAC-3 (VA 30) Circuit Breaker 10 I VIAC-2 (VA 20) Circuit Breaker 17 j VIAC-2 (VA 20) . Circuit Breaker 18 ( VIAC-4 (VA 40) Circuit Breaker 12 [- 5.2 Detectors and bistables must meet calibration requirements as I per Technical Specification requirements,.Section 4.3.2.1.1.
- 6. PRECAUTIONS l
6.1 Do not test more than one channel at a time. l 6.2 When shutting down, ensure Main Steam Isolation Actuation trips ! are blocked prior to decreasing steam generator pressure below 520 PSIA. 6.3 The manual pushbuttons on C01 are used only to manually initiate l safeguards actuation. 6.4 When cooling down and depressurizing the Reactor Coolant System, ensure the Pressurizer Pressure Channel trips are blocked (SIAS Block) prior to decreasing coolant pressure below 1620 PSIA. i 6.5 Do not test a parameter in which one channel is already tripped. LL 1 l
OP 2384 Page 4 Rev. 2
.( 6.6 If an ESAS actuation has occurred and the signal cannot be reset, all equipment shall remain in the actuated condition unless (1) personnel or equipment safety will be affected, (2) specific operating procedures allow or require the signal to be cverridden, or (3) the equipment is n,ot required for the mode.
If the signal to any equipment is overridden, credit for operability shall not be taken and the requirements of the appropriate action statement met. Bypass (override) status of ESAS actuated components shall be determined per surveillance shift checks.
- 7. PROCEDURE 7.1 Power Application NOTE: This section should only be performed when the ESAS is initially de-energized.
NOTE: Refer to section 7.9 or 7.10 for restoration of ESAS cabinets (sensors and actuation) following loss of a ( vital instrument AC Bus (VA-10, 20, 30, or 40) or a fault resulting in sensor cabinet trips, actuation module trips, blown -15V, -15V, or +24V fuses on the actuation cabinets. 7.1.1 Bypass each sensor cabinet's inputs before energizing the cabinets. 7.1.2 Supply 120 VAC to the ESAS sensor cabinets and the actuation cabinets: a) At VIAC-1 CLOSE Breaker 14 (VA 1014) b) At VIAC-1 CLOSE Breaker 18 (VA 1018) c) At VIAC-2 CLOSE Breaker 17 (VA 2017) d) At VIAC-2 CLOSE Breaker 18 (VA 2018) e) At VIAC-3 CLOSE ireaker 10 (VA 3010) f) At VIAC-4 CLOSE Breaker 12 (VA 4012) 7.1.3 Reset any bistable module trip lamps (red) that are lighted, by depressing lamp. k m

, 7. 7 Auto Test Inserter (ATI) - Cabinet 5 NOTE:
The ATI unit performs a recurring test sequencing operation which -is repeated every 27 seconds. It generates the dual 2 as pulses whicn are routed to ' each channel bistable (in combinations) to simulate a
~
momentary fault trip for test purposes. Each channel is tested end-to-end in a programmed sequence. All test results are routed back to the 6N91 module over reset lines. Each bistable test status is synchronously sampled during its test time by timing pulses. The test results are indicated locally by a panel ATI fault lamp. The testing sequence order is: a) SG A Press, SG B Press, UV-2A, UV-4A,' Area Exhaust Radiation, RWST Level, Pressurizer Pressure, Containment Pressure Hi and Containment Pressure Hi-H1; using two channels at a time: ( Channels A and B, A and C, A and D, B and C, B and D, C and D. b) Containment Radiation Ch A, Containment Raalation Ch 8, Containment Radiation Ch C, Containment Radiation Ch D. c) Sequence A, Sequence B. 7.7.1 Refer to SP 2619A for shift check of ATI operation. l 7.8 Actuated Equipment Override
- NOTE
Components which receive ESAS actuation signals are provided with control schemes to allow override of the actuation signal and positioning / operation of the component to a condition other than that called for by ESAS. NOTE: Certain of the ESAS actuated components receive dual actuation signals, and overriding the actuation of ' the component with one actuation signal present also prevents actuation by the other signal. The following l components receiving dual actuation signals are of this type:
