. P This Standing Order is intended to provide basic guidance for Operations to ensure consistent response at varying levels of unidentified RCS leakage. This Standing Order is not intended to change any responses or actions dictated by the CCOM, the Tech Specs,or any other Operational guidance.

Definitions:

Unidentified RCS Leakage Leakage from the RCS that has not been determined to be from a specific source. For example, iftotal RCS leakage has been determined to be 0.6GPM,but 0.4 GPM has been detmmined to be from 12 Charging Pump primary packing leakage, then the unidentified RCS leakage, as referred to in this Standing Order, would be 0.2 GPM.

r i

onsiderations:

Historical baseline RCS leakage for both units has typically been in the range of 0.1 GPM to 0.15 GPM following a refueling outage. This value tends to increase over the fuel cycle due to minor degradations of RCS sealing interfaces(e.$,

packing, etc...). Larger leakrates are typically seen very near the end of a fuel cycle (during times of increased CVCS diversion) due to inaccuracies in the diversion integrator, Calculated leakrate values will be greatly impacted by non-steady-state operation.

Consideration of minor changes in RCS leakrates should be given only when the RCS has been in steady-state conditions.

0 The sensitivity of the Containment Gaseous and Particulate detectors is based on a source term with 1%-failedfuel. Therefore, these detectors will be essentially blind to leakage within the range of this Standing Order.

0 The values presented in this Standing Order are to be considered general guidance. Plant conditions may dictate that actions be taken prior to these values being reached.

Any actions taken to attempt to identifysources of unidentified RCS leakage should be documented in the CRO logs (e.g., Quantifiedcharging pump primary leakage per OMA. No primary feakage detected.) This will ensure efficiency in the search, should it go over several shifts.

Small changes in RCS leakage may need to be trended over several shifts before actions to find leakage need to be taken.

B Single evolutions that cause the planned loss of RCS inventory (but ate not leakage)should be annotated in the CRO logs. Examples include large quantities of charging pump venting (such as restoring from maintenance), large diversion activities (such as rinsing a CVCS IX), etc,. .

BASES t BACKGROUND The s t a t i o n DC sources provide the AC emergency power system w i t h control power. I t also provides b o t h motive and

. control power t o selected safety related equipment and preferred AC vital bus power (via inverters). As required by Reference 1, Appendix I C , Criterion 39, the DC e l e c t r i c a l 1 power sources are designed t o have sufficient independence, redundancy, and testabil i t y t o perform their safety functions, assuming a single f a i l u r e . The DC sources also conform t o the recommendations of References 2 and 3. . I The 125 VDC electrical power sources consist O f .four independent and redundant safety related Class 1E DC channels. Each channel consists of one 125 VDC battery, the associated battery charger for each battery, and a l l the associated control equipment and intercomecti ng cab1 i ng .

During nor&l operation, 'the 125 VDC load i s powered'.from the battery chargers w i t h the batteries f l o a t i n g on the .

system. In cases where momentary loads are greater than 'the charger capability, o r a loss o f normal power t o the battery charger, ,the DC load is. automatically powered from t h e s t a t i o n batteries.

.The DC channels provide the control power for i t s associated Class 1E AC power 'load group, 4.16 kV switchgear, and 480 V load centers. The DC channels also provide a DC source t o the i'nverters, which i n turn power the AC v'i.ta1 b.uses.

The DC sources.are described i n mo.re detail in' the Bases for LCO 3.8.9 and f o r LCO 3.8.10. ' I Each battery has adequate storage capacity t o carry the

I' Each 125 VDC battery is separately housed i n a ventilated room apart from i t s charger and d i s t r i b u t i o n centers. Each channel i s separated physical 1y and el ectrical ly from the other channel t o ensure t h a t a single f a i l u r e i n one channel i does not cause a f a i l u r e i n a redundant channel.

APPLICABILITY The DC sources are required t o be OPERABLE i n MODEs 1, 2, 3, 1 and 4 t o ensure safe u n i t operation and t o ensure that:

a. Acceptable fuel design limits and reactor coolant pressure boundary limits are not exceeded as a r e s u l t o f AOOs or abnormal transients; and b.' Adequate core cooling is provided, and containment '

The DC sources requirement for MODEs 5 and 6 are addressed

.in the Bases for LCO 3.8,5. I ACTIONS ' -

A.1' Required Action A . l requires the inoperable battery t o be replaced by the reserve battery w i t h i n four hours when one DC channel 'is inoperable due t o an .inoperable battery and the reserve battery is available.

BASES 1 BACKGROUND . The onsite Class 1E AC, DC, and AC vital bus Electrical Power Di s t r i buti on Systems are divided 5 nto two redundant and independent AC electrical power dS s t r i bution subsystems and four independent and redundant DC and AC vital bus

. electrical power distribution subsystems (Reference I, Chapter 8) .

The AC primary Electrical Power Distribution System consists of two 4.16 kV ESF buses, each having a t least one separate and independent o f f s i t e source of power as well as a dedicated onsite DG source. Each 4.16 kV ESF bus i s normally connected t o a preferred o f f s i t e source. After a loss of the preferred o f f s i t e power source t o a 4.16 kV ESF bus, the onsite emergency DG supplies power t o the 4.16 kV ESF bus. Control power for the 4.16 kV breakers i s supplied from the Class 1E batteries. Additional description of t h i s system may be found in the Bases f o r LCOs 3.8.1 and 3.8,4.

The 480 V system include the safety-re1 ated Ioad centers, motor control centers, and d.i stri buti on panel s shown i n Table B .3.8,9-1.

The 120 VAC vital buses are divided into four independent and isolated subsystems and are normally supplied from an inverter. The alternate power supply f o r the vital buses are non-Class 1 E 120 VAC Buses fed from a Class 1E ESF motor control center through the regulating transformer, and i t s use i s governed by LCO 3.8.7. Each constant voltage source transformer i s powered from a Class 1E AC bus.

There are four independent 125 VDC electrical power distribution subsystems The l i s t of a l l required Distribution Systems-Operating i s presented i n Table B 3.8.9-1.

OPERABLE.

Maintaining the AC, DC, and AC v i t a l bus electrical power distribution subsystems OPERABLE ensures that the redundancy incorporated into the design of ESF i s not defeated.

Therefore, a single failure w i t h i n any system or w i t h i n the electrical power d i s t r i b u t i o n subsystems w i 11 not prevent safe shutdown o f the reactor.

ACTIONS -

A.l With one or more required AC buses, load centers, motor control centers, or d i stri b u t i on panel s, except AC v i tal buses, inoperable and a loss o f function has n o t yet occurred, the remaining AC electrical power d i s t r i b u t i o n subsystems are capable of supporting the minimum safety functions necessary t o shut down the reactor and maintain i t i n a safe shutdown condition, assuming no single failure.

The overall reliability i s reduced, however, because a single failure i n the remaining power d i s t r i b u t i o n subsystems could result i n the minimum required ESF functions n o t being supported. Therefore, the required AC buses, load centers, motor control centers, and distribution panels must be restored t o OPERABLE status w i t h i n eight hours.

Condition A worst scenario is one train w i t h o u t AC power (i.e., no o f f s i t e power t o the train and the associated DG inoperable). In this condition, the u n i t i s more vulnerable t o a complete loss of AC power. I t i s , therefore, imperative t h a t the u n i t operator's attention be focused on minimizing the potential f o r loss of power t o the remaining train by stabilizing the u n i t , and on restoring power t o the affected train. The eight hour time limit before requiring I a u n i t shutdown in this condition is acceptable because of:

a , The potential for decreased safety i f the u n i t operator's attention i s diverted from the evaluations and actions necessary t o restore power t o the affected t r a i n , t o the actions associated w i t h taking the u n i t t o shutdown within this time limit; and

b. The potential f o r an event i n conjunction with a single failure o f a redundant component i n t h e t r a i n w i t h AC power.

The second Completion Time for Required Action A . l establishes a limit on the maximum time allowed f o r any i combination of requi red distribution subsystems t o be inoperable during any single contiguous occurrence of failing t o meet the LCO. If Condition A is entered while, f o r instance, a DC bus i s inoperable and subsequently restored OPERABLE, the LCO may already have been not met f o r up t o two hours.

B.l With one o r more AC v i t a l buses inoperable and a l o s s of Function has n o t yet occurred, the remaining OPERABLE AC v i t a l buses are capable o f supporting the minimum safety functions necessary t o s h u t down the u n i t and maintain i t i n the s a f e shutdown condition. Overall re1 iabi 1i t y i s reduced, however, since an additional single f a i l u r e could result i n the minimum required ESF functions not being supported. Therefore, the AC v i t a l bus must be restored t o OPERABLE status w i t h i n two hours by powering the bus from an I associated inverter via DC o r the non-Class 1E 120 VAC bus powered by an ESF motor control center through a regulating I transformer .

Condition B represents one o r more AC v i t a l buses without power; potentially b o t h the DC source and the associated AC source are non-functioning. I n this situation, the u n i t is [

significantly more vulnerable t o a complete l o s s of a l l noninterruptible power. I t is, therefore, imperative t h a t the operator's attention focus on stabilizing the u n i t ,

minimizing the potential f o r loss of power t o the remaining v i t a l buses, and restoring power t o the affected v i t a l bus.

a. The potential f o r decreased safety by requiring a change i n u n i t conditions (i.e., requiring a shutdown) and not allowing stable operations t o continue;

b.

A t t h i s time, an AC t r a i n could again become inoperable, and v i t a l bus d i s t r i b u t i o n restored OPERABLE. This could continue indefinitely.

This Completion Time allows f o r an exception t o the normal "time zero" for beginning the allowed outage time atclock.ll This will result in establishing the "time zero" a t the time the LCO was i n i t i a l l y not met, instead of the time Condition B was entered.

The overall r e l i a b i l i t y i s reduced, however, because a single f a i l u r e in the remaining DC electri cal power d i stri buti on subsystem could result i n the minimum required ESF functions not being supported.

Therefore, the DC bus must be restored t o OPERABLE status w i t h i n two hours by powering the bus from the associated battery or charger.

A. Secure the remaining RCPs to prevent exceeding pump curve limits.

B. Throttle HPSl flow to allow for backflow from the affected S/G as RCS depressurization continues.

4.Lower TBV controller output to avoid exceeding cooldown rate limits when HPSl injection begins.

0. Increase RCS depressurization using Main Spray to lower the leak rate into the affected S/G.

A is incorrect, at 485"F, pumps can be run to 850 PSIA.

B is incorrect, HPSl throttling is not permitted below 101" PZR level.

C is correct, HPSl injection will start at about 1270 PSIA and will increase RCS cooldown rate as Cooler RWT water is injected.

D is incorrect, although depressurization is a main goal of the procedure, with these conditions, the RCS cooldown rate would be exceeded if injection occurs before steaming rate is reduced.

A. Align a HPSl pump to the suction of a CS PP if discharge pressure lowers and amps fluctuate.

43. Verify Containment Sump level rises as RWT level lowers and, after RAS has initiated, place a second CC HX in service.

c. Prior to RAS, place both CS PPs in PULL TO LOCK. Verify sump level is greater than 28". When RAS actuates, place a second CC HX is in service.

D. When RWT level lowers to 4 feet, throttle CS PP discharge valves per EOP attachments. After RAS has initiated, verify flow less than 1300 GPM.

A is incorrect, but aligning a CS PP to the suction of a HPSl PP is directed in the EOP if a HPSl is cavitating.

B is correct per EOP 5, Rev.19 Section IV, steps P and S.

C is incorrect, but there is direction to verify the sump has at least 28l of water in it.
