DCP 2&3-2077.OOSE REV. 0 PAGE is1 SECTION 1 - DESCRIPTION OF CHANGE D)ESIGN CHANGE TTLLE: CONTAiMENT ECUs SEQUENCE TIME MODIFICATTON

1. DESCRIPTION OF CHANGE 1.A REASON FOR THE CHANGE NRC Information Notice (A) 96-45 was issued on August 12, 1996 to alert licensees to a potential common-mode post-accident failure of the Containment Coolers (Emergency Cooling Units, or ECUs at SONGS). The failure involves water contained in the ECUs potentially flashing to steam during a design basis accident (LOCA or MSLB) with a concurent klss of preferred (offsite) power, or with a delayed sequencing of safety related equipment. In these cases, the ECU fan may force high temperature containment atmosphere across the cooling coils with no cooling water flow, causing the formation of steam in the cooling coils. The steam would reduce the heat transfer capability of the cooler, and may cause a hydrodynamic transient (water hammer) when the steam is abruptly condensed as cooling water becomes available. This problem was originally discovered at the Diablo Canyon Nuclear Generating Station.

Specificaly at SONGS, subsequent to a Safety Injection Actuation Signal (SIAS) and a Containment Cooling Actuation Signal (CCAS), with or without a loss of the normal preferred (offsite) power source, the start of the Component Cooling Water (CCW) Pump lags that of the Containment ECU fan start. Following a SIAS (automatic actuation of SIAS and CCAS occur concurrently) and a loss of nonnal preferred power, the CCW pump is tripped then sequenced to start at approximately 15 seconds following EDG breaker closure (Le. approximately 25 seconds after the accident signal). For an accilent signal without loss of preferred power, a CCW pump which is not currently running (in standby) would be started approximately 15 seconds after the accident signal occurred. During these scenarios, the ECU fans are started without any sequencing delay, either at the time of the ED&

breaker closure or at the time of the accident signaL Thus, the ECUs would be operating prior to the CCW pumps.

As a result of the the CCW pump sequencing delay, the Containment ECU fans operate with stagnant cooling water in the coils. Due to the incrased temperatures experienced in containment during post accident conditions, this stagnant water may be partially or completely evaporated by the operation of the ECU fan. Hence, initiating CCW flow to the ECU at the time the steam bubble exists would cause a sudden increase in CCW system pressure, quickly forcing the steam back into a liquid form.

The collapse of the steam bubble will result in an undesirable CCW system transient, creating a potentiilly damaging water hammer affect. The design of the Containment ECUs, with copper-nickel tubing and brazed conmections, makes them vulnerable to such hydrodynamic transients. If the CCW line should rupture, ECU heat removal would be lost and the subsequent loss of component cooling inventory would threaten operation of the CCW train.

DCP 2&3-2077.COSE REV. 0 PAGE 19 SECTION I - DESCRIPTION OF CHANGE Action Request (AR) 960801324 AR 960801324 was initiated to address the issues raised by IN 96-45, This AR discusses the Containment ECU operation during a design basis accident (LOCA or MSLB) with or without concurrent loss of preferred power. Three concerns were identified in the AR for the SONGS ECUs:

1. ECU Start Sequence (the ECU fans start prior to the CCW pump start)

NCR 960801324 Revision 0, Disposition item 3 recommends to delay the start time of the ECUs until after the CCW pump starts.

2. ECU Surveillance during Modes 1-4 (the ECU fan may be running at the time of accident initiation thus causing additional heat transfer and steam formation in the cooling coils)

3. Interruption of Cooling Water Flow (single failure which results in the loss of flow to the ECUs)

In each case, the potential exists for steam to be formed in the cooling coils of the ECU which may impact the ability of the CCW and the ECU systems to perform their design finctions. This DCP addresses only item I above. All other issues are addressed in the disposition of the related NCR 960801324.

Action Request (AR) 960900406 An additional design change included in this DCP is based on AR 960900406. This AR documented that a LOVS trip signal (4 seconds delayed LOVS/SDVS, or DGVSS) to Containment Dome Air Circulating Fan A074 is shared by the other Dome Fan A071 and the Control Room Emergency A/C (CREAC) Unit E418 in the same train. The LOVS reset signal (LOVS, SDVS or DGVSS reset relays VRI & VR2) is shared by both dome fans in a given train. Therefore, the loss of DC control power to fan A074 results in Fan A071 and the CREAC Unit E418 being inoperable. The same scenario applies to the Train B Dome Fans A073, A072 and CREAC Unit E419. The present design scheme could cause confusion to operators, create operational and maintenance restrictions and reduce the overall flexibility in operating these components.

IDCP 2&3-2077.OOSE REV. 0 PAGE 2 Io SECTION 1 - DESCRIPTION OF CHANGE 1LB FUNCTIONAL OBJECTIVE OF TE CHANGE I .B. 1 Background and Existing Configurations The CCW system for Units 2&3 is a closed loop intermediate heat removal system between radioactive or potentially radioactive systems and the Pacific Ocean. The CCW system has two completely redundant cooling loops. Two of the CCW pump motors are train aligned, and the third is a swing pump capable of being manually aligned to either the Train A or Train B. Each CCW loop supplies cooling water to two Containment Emergency Cooling Units (Train A, ME399 and ME40 1; Train B, ME400 and ME402). Following an accident that results in high containment pressure or low pressurizer pressure, a Safety Injection Actuation Signal (SIAS) and a Containment Cooling Actuation Signal (CCAS) are generated. Following a SIAS, two of the three CCW punps will start, one on each train. The SIAS causes the preferred Train A and Train B CCW pump to start at 15 seconds (approximately 25 seconds if a loss of preferred power has also occurred) after SIAS/CCAS initiation. In the existing configuration, a CCAS (with no time delay) causes the supply and return valves to the Train A and Train B ECUs to open (these valves are currently kept open during normal operation), and the ECU fans to start.

The discussion for existing configurations of the Containment Dome Air Circulating Fans and the Control Room Emergency A/C Unit circuit fimctions is included in DCP Sections I .B.3 and l B.4.

I.B.2 Containment ECUs Sequencing Time Control Circuit Modifications In order to increase the margin to forming steam in the ECUs, CCW flow needs to be established prior to starting the ECU fan. To reduce the potential for the formation of steam following the failure of a CCW pump, the ECU fan needs to trip (stop) when the CCW pump is not running. To accomplish this, modifications to the ECU start and stop circuits are made. These changes address NCR 960801324 Revision 0 Disposition item 3, and provide the following for each train of CCWIECU:

(a) Stop ECU fan with a CCAS present and no CCW pump running.

A CCW pump will not be running if either it was stripped due to loss of preferred power (LOVS trip) or if the pump was not running (in standby) at the time of the accident signal.

This new ECU interlock assures that if the ECU fan is running it will not continue to run with a CCAS present and no CCW pump running. If a CCAS is present, the ECU will be blocked from starting with no CCW pump running. The impact of the ECU fan coast down after tripping is addressed in NCR 960801324.

A:ASECT1 .WPD

DCP 2&3-2077.OOSE REV. 0 PAGE 2-SECTION 1 - DESCRIPTION OF CHANGE (b) Start ECU fan following a CCAS and the associated CCW pump running.

After a SLAS, the CCW pump is sequenced on after a delay of approximately 15 seconds (if it was not running) with no loss of preferred power. This ECU circuit modification will allow the ECU fan to start only if a CCW pump in the same train is running. Once the CCW pump starts, a timer in the ECU circuit introduces a nominal 5 second time delay before the ECU fan starts. Hence, the ECU fan is started approximately 5 seconds after the CCW pump starts. If at the time of the accident signal the CCW pump is already running, the pump continues to run and the ECU fan will start approximately 5 seconds after the accident signal.

This modification assures that the ECU fan is not started without a CCW pump running, and introduces a conservative time delay. There is no change to the ECU isolation valve logic included in this DCP.

If a loss of normal preferred power is associated with the accident scenario (CCAS and LOVS), the ECU start time will remain at 5 seconds after the CCW pump start, but will now be approximately 30 seconds (same as starting sequence 5) after the accident signal due to the Emergency Diesel Generator breaker closure time at approximately 10 seconds after the accident signal occurs. The additional 5 second delay for the start of the ECUs also facilitates a less severe EDG dynamic loading effect at starting sequence 4 (approximately 589kW) versus starting sequence 5 (approximately 331kW). See also Section l .D. 13 of the DCP.

In the absence of forced air flow around the ECU cooling coils, the rate of heat transfer is not expected to be great enough in the short term to form steam in the cooling coils. This is primarily based on the conduction heat transfer coefficient which is significantly lower than the forced convection heat transfer coefficient that dominates with the fan running.

For a design basis LOCA, the worst case event includes a loss of offsite power (LOVS). The LOVS maximizes the ESFAS response time due to the delayed sequencing associated with the diesel generator start. However, for an MSLB, the worst case accident does not include a LOVS. The availability of offsite power during an MSLB maintains forced circulation in the reactor coolant system (RCS) which supports a higher heat transfer rate across the steam generators and consequently a higher containnent temperature. Implementation of this design change increases the containment cooling response time. For a LOCA, the bounding scenario response time increases from 21.2 seconds to 47 seconds (with LOVS). For an MSLB, the bounding scenario response time increases to 37 seconds (no LOVS). These changes are well within the assumed start time as defined in calculation N-4080-026 (50 seconds for MSLB, 60 seconds for LOCA).

OCP 2&3-2077.OOSE REV. 0 PAGE SECTION I - DESCRIPTION OF CHANGE I.B.3 Containment Dome Air Circulating Fans Control Circuit Modifications This DCP also performs control and status indication circuit changes to the Containment Dome Air Circulating Fans A071, A072, A073 and A074. In Train A, A074 is the "mastere fan and A071 is the "slaver fan. In Train B, A073 is the "master" fan and A072 is the "slave" fan. Both fans (master and slave) of one train are currently stripped and sequenced "on" by control devices located in the circuit for the master fan. For example, the 2-out-of-4 loss of power trip logic (LOVS) is monitored by auxiliary relay 86-2 in the master fan circuit. Contacts from this relay are then used to trip both the master and slave dome fins. Removing the control power or otherwise disabling the master fan control circuit makes both fans inoperable and unable to trip on a LOVS. In order for operators to be alerted of tis condition, the loss of control voltage/inoperable status control room indication logic for the slave fan is modified in this DCP_ See NCR 960900406 Revision 0, Disposition item 2.

After DCP implementation, the slave fan (A071, A072) will illuminate the inoperable light on the ESF bypass inoperable status panel when the master fan control circuit is unavailable. If the master fan needs to be cleared for work (with no work needed on the master fan control circuit), the master fan breaker can be racked out and the master fan DC control power turned back on to make the slave fan operable. In this situation, the ESF bypass inoperable status panel will recognize the master fan as being inoperable and the slave fan as being operable.

This DCP also relocates the breaker position contact of the slave dome fan from the start circuit of the slave fan to the start circuit of the master fan. The master fan control circuit contains the load sequencing relay for both fans. This change will assure that the sequencing relay will not be deenergized before both the master and slave fan breakers are closed. The use of the breaker position contacts in the close circuit eliminates a continuous signal to the breaker close circuit mechanism.

This ensures that if the 480V loadcenter becomes de-energized and subsequently re-energized, the fans will not start immediately, but start only after their delayed sequencing period. This results in a less severe transient for the diesel generator upon bus re-energization. In the existing Unit 3 configuration, neither breaker position contact was included in the start circuit of these fans. This DCP modifies the Unit 3 circuitry to be the same design scheme as Unit 2. There have been no recorded filures to date with the current design in either Unit 2 or 3. However, this change results in a more robust design for this equipment.

1.B.4 Control Room Emergency A/C (CREAC) Units Control Circuit Modifications This DCP modifies the control circuits for the Control Room Emergency A/C (CREAC) Units E418 and E419 so that they are independent from the Containment Dome Air Circulating "master" fan control circuitry. Currently, the CREAC units will trip from an auxiliary relay contact controlled by the master dome fan LOVS logic in order to strip this load from the 480V bus prior to load sequencing to the EDG. Currently, if the master dome fan control circuit is made inoperable, the CREAC unit is also inoperable and unable to strip on LOV'S. This DCP connects a spare 2-out-of-4 LOVS logic at the 4kV switchgear to the CREAC unit's trip circuit. The currently used contact of the auxiliary relay from the master dome fan control circuit will be removed from the CREAC unit's AASECTw.Wpo

IDCOP 2&3-2077.OOSE REV. 0 PAGE 2 SECTION I - DESCRIPTION OF CHANGE 1I.C IMPACT OF THE CHANGE ON SITE PROGRAMS Site Impact Form 26-404 is included in Section 10, which facilitates changes to Station procedures and programs. Items referred to below are related to the corresponding parts of the form that have a positive response.

I .C. 1 Operations Impact (a) ITEM A: The only requirements for establishing equipment/system operability are related to the post-modification testing which will verify that the changes to the ESFAS circuitry are performing as designed. Functional testing of the modification may be performed using existing surveillance procedures (modified to accommodate this DCP). All other requirements for establishing the operability of the Containment Cooling system and the Component Cooling Water system remain unchanged.

The master Containment Dome Air Circulating Fan control circuit will continue to be required (in service) for the slave dome fan to be operable. The ESF bypass inoperable panel will indicate the slave fan inoperable status when the master control circuit is not available.

(b) ITEM F: The control circuit design modifiation for the Containment Dome Air Circulating Fans and Control Room Emergency A/C (CREAC) Units will provide independence between the control circuis of this equipment. The CREAC control circuit LOVS trip function will be made totally irdepeent of the containment dome fan LOVS trip circuit. The two containment dome fans of the sane main will remain interlocked (LOVS trip and LOVS reset close), with the slave fan mopeable saums irdication policing this interlock. Master and slave dome fans are assigned separate inoperable status lights. This circuit modification will actuate the "slave:" dome fan inoperable status indication if the "master" dome fan circuit is made inoperable. See also (d) below.

(c) ITEM G: The design change adds an interlock to provide a delayed start of the ECU fan in response to a CCAS. Currently the ECU fan starts at time -0 following a CCAS and LOVS reset. Upon implementation of this change, the ECU fans will not start until 5 seconds after the CCW pumps start (nominally at 20 seconds after the accident signal if the CCW pump was not running). If the CCW pump is already unning, the ECU will start approximately 5 seconds after CCAS is initiated. If no CCW pump is running, the associated ECU fans will not start and will be stopped if already running. The ECU fans will automatically restart (after a 5 second delay) if a CCW pump on the corresponding train is starte Additional operating restrictions related to the ECUs, but not associated with the changes included in this DCP, can be found in the disposition to NCR 960801324. There are no changes to the manual control circuits for the ECUs.

(d) ITEM H: New components are powered from the 125VDC control power located at the 480V loadcenters. These power sources are existing, and no change is being introduced to revise the protection schemes or the power source daisy chain through the loadcenter sections.

C:5ETWPe1\o>CP2o7,7o~rCT1.WPO)

DCP 2&3-2077.OOSE REV. 0 PAGE 2- j SECTION 1 - DESCRIPTION OF CHANGE (e) ITEM I: For this DCP, failure of a CCW pump to start indication will remain unchanged.

Currently, circuit breaker status for the ECU fan is indicated by the breaker status lights at CR60.

There is no alarm to alert operators of a failed ECU start and this will remain as such.

The loss of control voltage/inoperable status indication for the Containment Dome Air Circulating Fans will be interlocked such that if the master dome fan becomes inoperable due to deenergization of the control circuit, the inoperable status indication will be generated for both the master and slave dome fans [e.g. (A074 and A071) or (A073 and A072)] at the control room inoperable status indicating lights. The inoperable status alarms are annunciated on windows 2(3)UA0057A56 and 2(3)UA0057B56 and the inoperable indication is on 2(3)HS0065 and 2(3)HS0066 at CR57. There are no physical changes to the bypass inoperable status panel lights or the annunciator windows themselves.

The Control Room Emergency A/C (CREAC) Unit LOVS trip will be made independent of the master Containment Dome Air Circulating Fan circuitry. Administrative controls (

Reference:

AR 96090406, Revision 0, Assignment OTH) now in place for the dome fans and CREAC unit at the circuit breakers for this equipment shall be removed after implementation of this DCP.

(f) ITEM J: The ECU fans will be interlocked to the CCW pumps in the same train with a CCAS present. See paragraph I C. I (c) above.

(g) ITEM L: See paragraph 1.C. I (c) & (e) above for the summary of changes being made in this DCP. The eisting Teclnical Specification surveillance procedures need to be revised to include the new interlocks as shown in this DCP.

1 C.2 Operations/Maintenance Impact (a) ITEM A: This DCP does not introduce any changes to plant mode or system alignment requirements associated with surveillance testing. In addition, the existing Technical Specification surveillance procedures need to be revised to include the new interlocks as shown in this DCP.

However, the disposition of NCR 960801324 does require that certain conditions be met prior to starting the ECU fan for surveillance testing. Refer to the NCR disposition for more information.

(b) ITEM B: The control room simulator will require a logic update based on this DCP for the following:

1. The ECU fans will be interlocked to the CCW pumps in the same train with a CCAS present.

The fan will start approximately 5 seconds after the associated CCW pump breaker closes.

2. The slave Cntnt Dome Air Circ. Fan inoperable status indication will be interlocked with the master dome fan control circuit.

SECTION 1 -DESCRIPTION OF CHANGE

3. The Control Room Emergency A/C Unit will trip directly from the LOVS relays and not via an auxiliary relay located in the master Cntmt Dome Air Circ. Fan control circuit.

See paragraph 1.C. 1 (c) & (e) above.

(c) ITEM C: The new Agastat relays will require calibration and testing to their assigned settings The relays of the ECU close circuit (62-1) are set at 5 seconds and the trip circuit relays (62-2) are set at 1 second. The SONGS Technical Specification SR3 .81.18 allows a maximum sequencing time tolerance of 10%/o of the time interval (5 +/-0.5 seconds for this case). For the 62-1 relays, the acceptance criteria for the Integrated ESE Test would be actual CCW pump breaker closure plus 5 +/-O.5 seconds. PCN-454 (in process) revises the tolerance indicated in SR3.8.1.18 to -10% of the relay setting or 2.5 seconds, whichever is larger (except for the 5 second load group which is -0.51+2.5 seconds). Thus, after the approval of PCN-454, the relay acceptance test criteria will be actual CCW pump breaker closure plus 5 seconds -0.5/+2.5 seconds. Relay 62-2 only removes the breaker trip signal after approximately one second and is not part of the load sequencing. Relays shall be included in the refudeing outage recalibration tests and other applicable or emergent component level programs.

(d) ITEM D: The ESFAS response time for the ECU fans and for the Emergency Diesel Generator loading are being changed as a result of tis DCP. The current start time for the ECU fans is at time = 0 seconds after CCAS and LOVS reset. Upon implementation of this DCP, the ECU fans will start 5 seconds after the CCW pumps start. Procedures used to verify ESFAS response time for the ECUs need to be updated accordingly [see subsection (f) below). The design modification results in a system response time change from 21.2 seconds to 47 seconds, but remains within the assumed response time specified in the safety analysis. The DCP also modifies the trip initiation for the Control Room Enmergcy A/C (CREAC) Unit. The trip is revised from an auxiliary relay located in the Cntmt. Dome Air Circ. Fan control circuit to the LOVS relay contacts located in the 4kV switchgear. The spare LOVS relay contacts which this DCP assigns to the CREAC unit are required to be included in applicable TS surveillance procedures.

(e) ITEM E: Class IE batteries and Emergency Diesel Generator loading calculations are affected by this change. The additional relay and 480V loadcenter breaker operation affect the battery loading within the first minute period only. However, the additional load does not affect the existing load profile used for cell sizing and surveillance test requirements of the battery. The ED& dynamic analysis during the load sequencing period is affected by the change in start time of the ECUs. Additional information is provided in Section 1.D. 13.

(f) ITEM F: The ECU fans will be interlocked to the CCW pumps in the same train with a CCAS present. Surveillance procedures which require starting the ECU fans (with a simulated CCAS) will be affected by the new interlock. See paragraph L.C. 1 (c) & (e) above for details. As a minimum, the following procedures may be affected by this modification:

This wiring will be connected between the breaker auxiliary switches of the two adjacent CCW pump breakers cubicles, and to a terminal block of the train aligned CCW pump. An existing hole with an installed bushing is available to run directly between the adjacent CCW switchgear compartments.

The auxiliary switches are a 4-pole array operated by the circuit breaker position mechanical arm that extends from the breaker cubicle below. The switches are currently not used (spare). Field modifications to the auxiliary switches will have to be made, or replacement switches shall be installed, in order to convert the existing momentary contacts (of which there are 2) to maintained.

The final configuration of the auxiliary switches will then be two normally open and two normally closed with maintained contacts. This configuration will facilitate the start and trip function permissive for the ECU control circuits. None of the devices or control circuits for the CCW pump itself are affected by this DCP.

Field cable from the 480V loadcenter will be terminated at the tenninal block for the train aligned CCW pumps P024 and P026. No field wiring is required at the swing pump P025 cubicle as these are connected internally to the train aligned pump.

The Containment ECU, Dome Air Cire. Fan and Control Room Emergency A/C Unit circuit breakers are located in these loadcenters. Each loadceter wi have four Agastat relays instaed for the ECUs.

Two Agastat relays will be installed in the auxiliary compartment directly above the ECU breakers.

These relays provide the timing function for one of the ECUs. Due to lack of space, the two additional Agastat relays for the other ECU will be installed in another auxiliary compartment.

Wiring from these relays shall be brought to the rear of the loadeenter, where required, to connect to field terminal blocks or to be run between loadcenter cubicles. Field work at the rear of the loadeter is in close proxiity to live bus bars, and must be done with proper insulating methods or with a bus outage.

One HMA relay in each loadeenter for the done fan loss of control power inoperable status indication shall also be installed in the auxiliary compainent. These must be wired into the control circuit of the "master" dome fan by routing the wires to the rear of the loadcenter and then across to the applicable vertical section.

Field cables will be terminated at the terminal blocks in the rear of each loadeenter.

(d) Field Cable Cables will be installed between the Class IE switchgear and the loadcenter for the CCW interlocks to the ECUs, and for the LOVS trip to the Control Room Emergency A/C Units. All cable routing remains within the switchgear room. Existing trays and conduits shall be utilized.

The Unit 2 cable installation as described above are covered by an FCN package for allowing work to be performed before the U2C9 outage. The FCNs required for this pre-outage work are referenced in Section 4 (Construction Summary, Unit 2) and in paragraph (e) below.

In addition, new cables are installed in the 4kV switchgear moms by utilizing existing raceways. Spare breaker auxiliary switches, test switches, loss of power relay logic and terninal blocks are utilized where available. Material is classified as Safety Related (Quality Class 11). In order to maintain the seismic qualification of the Agastat E7000 relays, they must be mounted in the vertical position only. Seismic Qualification Report, SQTR 93103302, documents the acceptability of the Agastat E7012PB004 relays. The Agastat model E7012PC004 is physically the same as the Agastat E7012PB004 relay with the only difference being the time delay of 1.5-15 seconds versus 0.5-5.0 seconds. A sufficient variety of E7000 series relays of various voltages and time delays were tested and qualified in SQTR 93103302, SQTR 93113777 and SQTR 94-0917. A review of the functions of model E7012PC004 compared to those models that were tested indicates that model E7012PC004 is seismically qualified based on similaity to those qualified by testing. Additional seismic qualification inforimation on the Agastat relays may be found in Procurement Engineering Evaltation PEE 94-01. The HMArelay, model number I2HMAllB6, is considered qualified as an in-ind replacenxt of original components. Due to the HMA relays (model number 12HMAI 1B6) new location in the 480v Load Center, review of the original 480v Load Center Panel qualification report (S023-302-3-18l) was required The review revealed that the original relay was qualified for use at a location very close to the top of the panel, similar to the location of the new installation, therefore, the relay is qualified for use in this application.

DCP 2&3-2077.OOSE REV. 0 PAGE 3,3 SECTION I - DESCRIPTION OF CHANGE 1.D.6 Plant Layout and Arrangement Requirements Relay installation, cable installation through existing raceways, and internal cabinet wiring detailed in this DCP do not require any changes to be made to the plant layout or arrangement documents.

I.D.7 Environmental Conditions Equipment is installed in the 4kV switchgear rooms, Control Building, elevation 50'. This area is defined as a mild environment per DBD-S023-TR-EQ, Table 0-1.

I.D.8 Safety Requirements Since this modification will be perforrned in the Control Building El. 50', no special radiological safety requirements are required for the installation of the relays, wiring and cables. This installation will involve working near energized equipment, therefore, appropriate caution shall be taken when working inside the energized switchgear. Standard Construction Safety Procedures shall be followed to prevent undue risk to the health and safety of the construction and the operation personnel.

1.D.9 Quality Class and Seismic Category Per Appendix 3.2A of the UFSAR, the 4kV switchgear and 480V loadcenters are Quality Class II, Seismic Category I (SONGS 2&3 Q-list, Document 90034). The additional devices for installation in the 4kV switchgear and 480V loadcenters are specified for Quality Class II, Seismic Category I application. Cables and wiring are classified for Quality Class II application.

ID. I0 Other Requirements (a) Fire Protection1lOCFRSO Appendix R I& new cables installed in the switchgear rooms will impact the combustible loading in this area as shown in the UFHA. Appropriate changes are included in this DCP. For Unit 2, a UFHA change has been provided with the FCN package that performed the installation, and an information only copy has been provided in Section 3 of the DCP. Other fire protection issues are addressed in form 26-292 "Fire Protection Checklist". Appendix R compliance document changes are included in Section 4E of the DCP.

Equipment modified in this DCP are classified as safe shutdown components. However, all cable installations in this modification remain within the switchgear room, and therefore are bounded by the existing analysis. New cables are added to the compliance document database. Also, Appendix R credited fuises in the control circuits of the CCW pumps, the ECUs and the Emergency A/C Units C:\NETWP61MDCP2077flXSECT 1 .WP

DOCP 2&3-2077.00SE REV. 0 PAGE $4 SECTION I - DESCRIPTION OF CHANGE are not being modified in this DCP. Therefore, this design change does not impact the IOCFR50 Appendix R IIf.IGILL compliance assessment. The Appendix R analysis postulates that for fires in specific areas, the CCW pumps have tripped and manual actions are taken to restart the CCW pumps.

The ECU fans will automatically restart (with CCAS present) when the associated CCW pump is started. Therefore, no additional manual actions related to the ECUs will be required as a result of the changes in this DCP.

(b) Security Criteria There are no security requirements associated with the modifications proposed in this DCP.

(c) Environmental Qualification The switchgear rooms are defined as a mild area (DBD-S023-TR-EQ, Table 0-1). All devices insalled by this modification will not affect the existing harsh area environmental qualification criteria as defined in 10CFR50.49, or any environmentally qualified equipment or function covered by the SONGS harsh area EQ program.

(d) ESFAS Response Time Procedure S023-XV-6 This procedure has been superseded by a memo from the IPRE. A revision to this memo is required based on changes included in this DCP. ESFAS response times are governed by the LCS changes included in Section 3E, and a copy of the revised memo dated November 25, 1996 is included in Section 3.F of this DCP.

1.D. II Environmental Regulatory Requirements The work associated with this DCP and the resultant installation are confined to the areas previously disturbed during site preparation and plant construction. This change is essentially confined to electrical control ciruits within the ESF switchgear rooms. As such, the proposed changes will not have any non-radiological environmental impact.

ID. 12 Radioactive Waste Treatment System/Personnel Exposure Impact This modification does not change any radioactive waste treatment systems (liquid, gaseous and/or solid); nor does it change any release quantities and personnel exposure from those previously identified.

DOCP 20&-2077.00SE REV. 0 PAGE Z5 l SECTION 1 - DESCRIPTION OF CHANGE I.D.13 Electrical Loads Class LE Battery Loading This modification installs additional relays connected to the Class IE batteries and revises the 480V breaker trip and close timing for the ECUs. The DC loading scenario assumes, prior to the accident signal, that both ECUs were running for a surveillance test per S023-3-3.13. This results in a worst case loading condition for the battery.

Based on the tripping and closing 480V breaker DC load burdens indicated in E4C-017 and the DC burden for the additional relays, there is a change to the Class 1E battery loading. This change is indicated in Calculation E4C-0 17, ICCNs C-47 (Unit 2) and C048 (Unit 3) for batteries 2(3)B007 and 2(3)BOO8.

The additioarl loading does not cocide with the first minute peak loading period and remains within the contingency load margin for the remaining periods of the battery discharge cycle. Therefore, for these two cases, the surveillance test profiles for the batteries remain unchanged.

The DCP changes result in a revised first minute peak for the Station Blackout (SBO) scenario battery load profile. The additional loading coincides with the first minute peak loading period but will remain within the contingency load margin for the remaining periods of the battery discharge cycle. The cell size margin remains unchanged since the first minute loading does not represent the dominant loading period under the SBO scenario.

Class 1E Bus Loading/Emergency Diesel Generator DC]) Loading Steady-state Class 1E bus loading isnot changed based on this DCP. Also, the post-accident steady-state EDG loading is not affected by this modification since the DCP changes only the load sequencing time for the ECU fans. Hence, only the dynamic analysis for the Class 1E 4kV bus loading is affected by this change. The sequencing of the ECU fan start time is based on CCW system requirements per UFSAR Sections 6.2 and 9.2 (see DCP Sections L.B.2 and 3B), and riot due to QANETWP611DCP2077M~SEGTI.WP0

DCP 2&-2077.00SE REV. 0 PAGE 36 I SECTION I - DESCRIPTION OF CHANGE diesel generator loading restrictions. Several scenarios require analysis:

(a) For the case where at least one CCW pump is running prior to a SIAS/CCAS with no LOVS, the ECUs will be sequenced "on" at approximately 5 seconds after the accident signal.

(b) For the case where the CCW pump is not running prior to a SIAS/CCAS with no LOYS, the ECUs will be sequenced "on' at approximately 20 seconds after the accident signal.

(c) For the case where the CCW pump and the ECU are running prior to a SIAS/CCAS with no LOVS, the ECU will continue to run.

(d) For the case where no CCW pump is runing prior to a SIASfCCAS with a LOVS, the ECUs will be sequenced "on" at approximately 30 seconds after the accident signal (i.e. approximately 20 seconds after EDG breaker closure).

For cases (a), (b) and (c) the preferred (offsite) power source is available. EDG loading is not affected in these cases.

For case (d), EDG loading is affected by shifting the start time of the ECUs from time t -0 seconds (EDO breaker closure) to a time approximately 5 seconds after the CCW pumps start. Hence, approximately 124kW of load is moved from time t - 0 to time t = -20 seconds. Since the time 0 diesel gemerator load is approximately 1000kW and the time t = 20 load increase is approximately 330kW, this change reduces the burden at the diesel generator's most severe loading time at t -0.

However, unlike other EDO sequenced loads, the start time for the ECUs is based on two 'series" Agastat tiners (the CCW pump tiner and ECU timer). Therefore, the ECU sequenced start time will be defined as CCW pump actual breaker closure plus 5 +/-0.5 seconds.

Prior to approval and implenentation of PCN-454, the ECU timer acceptance criteria is actual CCW pump breaker closure time plus 5 +/-0.5seconds. Subsequent to the approval of PCN-454, the ECU timer acceptance criteria will be actual CCW pump breaker closure plus 5 -05/+2.5 seconds. See Section 3.A of the DCP for information related to PCN-454.

The cases discussed above are analyzed in calculation changes E4C-082, ICCNs C-22 (Unit 2) and C-23 (Unit 3). All possible overlapping load groups considering an Agastat timer tolerance of +2.5 seconds are evaluated. The ICCNs indicate that the results of the sequencing modification are acceptable and meet the criteria of SONGS Technical Specification 3.8.1.

Figures lA, lB and IC which follow, provide load sequencing time interval and ECU/CCW system response time information.

DCP 2&3-2077.OOSE REV. 0 PAGE __2-SECTION 2 - 10CFR50.59 SAFETY EVALUATION 2.A Containment Emergency Cooling Units/Component Cooling Water System The following responses address modification to the ECU/CCW system as explained in Section I and NCR 960801324, Revision 0, Disposition item 3.

1. hMay the proposed activity increase the probability of occurrence of an accident evaluated previously in the safety analysis report?

Response: No.

The Containment Emergency Cooling Units (ECUs) in conjunction with the CCW system are used to mitigate accidents. Neither the ECU nor the CCW are capable of causing an accident.

Their safety function is to transfer post accident containment heat to the SWC system via the CCW heat exchanger. The proposed design modification includes a delay in the ECU fan starting time. The change in the start time of the fans has no potential for creating or increasing the probability of an accident.

Therefore, the proposed activity will not increase the probability of occurrence of an accident previously evaluated in the safety analysis report.

2. May the proposed activity increase the consequences of an accident evaluated previously in the safety analysis report?

Response: No.

A water hammer could rupture the piping in the ECU which forms the containment boundary.

The proposed design modifcations assures that the CCW pump is running before starting the ECU fins, thereby increasing the margin of forming steam in the ECUs. The new ECU fan start time will be within the start time assumed in the post accident containment-pressure and temperature analysis. Moving the ECU fan start time within the bound of containment pressure-temperature (P-T) analyses for the design basis LOCA or MSLB event inside containment has no potential for increasing the consequences of an accident previously evaluated.

The delayed start of the ECU fans has been analyzed and does not compromise the safety function of the Class IE electrical system, the Emergency Diesel Generator or the Class lE batteries.

Therefore, the proposed activity will not increase the consequences of an accident previously evaluated in the safety analysis report.

A:\SECT2A.WPD

DCP 2&3-2077.00SE REV. 0 PAGE 43 l SECTION 2 - IOCFR50.59 SAFETY EVALUATION

3. May the proposed activity increase the probability of occurrence of a malfunction of equipment important to safety evaluated previously in the safety analysis report?

Response: No.

The proposed design modification changes the ECU fan start time and trip circuits to assure that the CCW pump is in operation or starts prior to ECU fan start during a design basis accident.

It also assures that the ECU fans stop if no CCW pump is running. By moving the ECU fan start time to after the CCW pump start time, it minimizes the possibility that the high temperature containment atmosphere will be forced across the ECU cooling coils without forced component cooling water flow through the ECU coils. This issue was not previously addressed in the safety analysis report. This design modification is a corrective action as prescribed in NCR 960801324, Revision 0, Disposition item 3.

or With the proposed design modification, the overall actuation time for the ECU fans, with the ECU fan is still without loss of offiite power, will increase. This increase in starting time of within the bound of the time actually used in the containment pressure-temperature (P-T) analyses for the design basis LOCA or MSLB events. Changing the start time within the bound of the assumed start time in these P-T analyses has no impact on the results of the analyses.

Therefore, the proposed modification, which moves the ECU fan start time to after the CCW pump start time, assures the CCW system continued operability.

The delayed start of the ECU fans has been analyzed and does not compromise the safety lE function of the Class 1E electrical system, the Emergency Diesel Generators or the Class batteries. The 5 second delay timer with a tolerance of +/-0.5 seconds meets the requirements of load SONGS Technical Specification SR 3.8.1.18 (+/-10%of design interval) for diesel generator sequencing. The modification also meets the proposed technical specification change of PCN-454, which requests a change to the tolerance of the 5 second load group to -0.5/+2.5 seconds.

The proposed modification will meet the design specifications for the material, equipment and construction practices. Seismic and separation criteria are met in performing the required changes to the 4kV switchgear and the 480V loadcenters. Relays added are of a type already The utilized in this equipment, and circuits are properly protected by interrupting devices.

UFSAR safety evaluations are based on control circuits as a whole, independent of the number of devices in a specific circuit. Therefore, adding devices to the existing control system would have no impact on the previously evaluated probability of the ECU control system failure.

The additional Class IE battery loading is analyzed and found to be acceptable. The operation of equipment important to safety is not compromised by this modification. Therefore, this design change will not adversely affect the capability of the Class IE 4kV and 480V electrical systems and the Class IE batteries. The proposed change does not degrade the performance of this equipment and their related safety functions in the mitigation of the accidents and events evaluated in the UFSAR Chapter 15.

A-sECT2A.WPD

DCP 2&3-2077.OOSE REV. 0 PAGE 4 4 SECTION 2 - IOCFR50.59 SAFETY EVALUATION Therefore, the proposed activity will not increase the probability of occurrence of a malfunction of equipment important to safety evaluated previously in the safety analysis report.

4. May the proposed activity increase the consequences of a malfunction of equipment important to safety evaluated previously in the safety analysis report?

Response: No.

The proposed modification will move the ECU fan start time with a CCAS signal after the CCW pump start time to assure the ECUs and the CCW systems are not susceptible to water hammer due to steam forming inthe ECU cooling coils prior to the start of the CCW pumps. The change will be accomplished without jeopardizing the overall ECU actuation time assumption used in the containment pressure-temperature (P-T) analyses for the design basis LOCA or MSLB events. The proposed modi&cation to the ECU circuh assures that during a design basis accident the CCW pump is running priorto the ECU fan starting, and that the ECU fan trips if the CCW pump is not running.

The analyzed consequences of any previously postulated malfunction of equipment important to safety will remain unchanged after this change is implemented.

Therefore, the proposed modification will not increase the consequences of a malfunction of equipment important to safety previously evaluated in the safety analysis report.

5. May the proposed activity create the possibility of an accident of a different type than any evaluated previously in the safety analysis report?

Response: No.

The proposed activity moves the ECU fan start time within the bound of the accident analyses and has no potential for creating the possibility of an accident of a different type than any evaluated previously in the safety analysis report A change in start time of the idle fan cannot create the possibility of any accident. The CCW system remains operable and will perform its safety function. Neither the ECU nor the CCW are capable of causing an accident.

The proposed modification will not affect the operation of the Class 1E electrical distribution system or the Class lE batteries. There are no reasonable or credible accident or event scenarios potentially associated with the Class lE electrical distribution system nor the Class IE batteries, affected by this design change, that are different from any of those previously evaluated in the UFSAR.

Therefore, this proposed change will not create the possibility of an accident of a different type than previously evaluated in the safety analysis report.

SECTION 2 - IOCFR50.59 SAFETY EVALUATION Technical Specification SR 3.8.1.18 indicates surveillance requirements to verify time intervals for the emergency diesel generator load sequencing. This proposed modification remains within the design bases as specified in the Technical Specification Bases 3.8.1. The proposed modification is also in compliance with the proposed new bases for SR 3.8.1.18 included in PCN-454. Thus, it is assured that Emergency Diesel Generator loading will not be overburdened to the point which would degrade its performance, or jeopardize its capability to achieve its designed safety function. Based on this proposed change, the ECU sequenced start time is dependent upon the CCW pump's start time. The safety margin of the emergency diesel generator is neither reduced nor compromised based on the delayed start of the ECU.

This is because the worst case load sequencing time for the Emergency Diesel Generator is at breaker closure (sequence tine t - 0). In addition, the margin of safety for the Class 1E batteries is not impacted. The battery load changes, based on this proposed change, do not occur at the most liniting period of the battery load profile. The battery load profile, available design margin and required surveillance test loading remain intact. Thus, the capability of the Emergency Diesel Generators and Class IE batteries to perform their required safety functions is fully maintained.

For a design basis accident scenario, existing calculations for the switchgear room remain bounding for the added heat load from the two Agastat relays in the 4kV switchgear.

Therefore, this proposed change will not reduce the margin of safety as defined in the basis for any technical specification.

DOP 2&3-2077.OOSE REV. 0 PAGE 47 SECTION 2 - 10CFR50.59 SAFETY EVALUATION 2.B Containment Dome Air Circulating Fans/Control Room Emergency A/C Units The proposed modification affects the start circuit clearing function and the inoperable status indication circuit for the Containment Dome Air Circulating Fans. The change consists of circuit modifications to the Containment Dome Air Circulating Fans A071, A072, A073 and A074. In Train A, A074 is the "m4 aster" fan and A07I isthe "slave" fan. In Train B, A073 is the "master" fan and A072 is the "slave" fan. Both fans (master and slave) of one train are stripped and sequenced 'on" by control devices located inthe circuit for the master fan. For load stripping, an auxiliary relay is used in the master dome fan circuit. This relay is actuated by the 2-out-of-4 LOVS logic relay contacts. The relay provides contacts for both the master and slave dome fan trip circuits. For starting, the time sequence for both fans iscontrolled by a timing relay in the master dome fan circuit. Again, a contact of this timer is used in the start circuit for the slave fan. Hence, removing the control power or otherwise disabling the master fan control circuit makes both fans inoperable. In order for operators to be alerted of this condition, the loss of control voltage/inoperable status control room indication logic for the slave fan is modified. The slave fan inoperable status indication will be changed to include a signal from the master fan via a new relay installed in the master fan control circuit. Thus, the inoperable condition for the master fan will also illuminate the slave fan control room inoperable status indicating light. This circuit enhancement will provide improved status information for plant operators.

The proposed modification also relocates the breaker position contact of the slave dome fan from the start circuit of the slave fan to the start circuit of the master fan. The use of the breaker position contacts in the close circuit eliminates a continuous signal to the breaker close circuit mechanism.

Clearing the start circuit signal is desirable if the bus should become de-energized for a short time and then re-energize. This allows the the dome fans to be re-sequenced onto the bus. The master fan control circuit contains the load sequencing relay for both fans. This change will assure that the sequencing relay will not be de-energized before both the master and slave fan breakers are closed, allowing a positive start of both dome fans.

The proposed rnodiication changes the control circuits for the Control Room Emergency A/C (CREAC)

Units E418 and E419 so that they are independent from the Containment Dome Air Circulating master fan control circuitry. Currently, the CREAC units are tripped via an auxiliary relay contact controlled by the master dome fan LOVS logic in order to strip this load from the 480V bus prior to load sequencing to the EDG. If the master dome fan control circuit is made inoperable, the CREAC unit is also inoperable and unable to strip on LOVS. The modification connects a spare 2-out-of-4 LOVS logic located at the 4kV switchgear directly to the CREAC unit's control circuit. The currently used contact of the auxiliary relay from the master dome fan control circuit will be removed from the CREAC unit's trip circuit and made spare. This results in a CREAC unit LOVS trip which is independent of the LOVS trip for the dome fans The CREAC start circuit, specifically the LOVS reset relays, was already independent from the dome fan circuit, and thus remains unchanged in this proposed modification.

IDCP 2&3-2077.OOSE REV. 0 PAGE 43' SECTION 2 - IOCFR50.59 SAFETY EVALUATION The following responses address modification to the to the Containment Dome Air Circulating Fans and the Control Room Emergency A/C Units circuit functions as explained in Section 1 and AR 960900406.

I. May the proposed activity increase the probability of occurrence of an accident evaluated previously in the safety analysis report?

Response: No.

The operational design basis of the Containment Dome Circulating Fans as explained in the UPSAR Section 9.4.1.2 remains valid. The modification and related installation activities meet the design, material and construction standards applicable to the Class 1E electrical equipment being modified. The modified start circuit and inoperable status indication circuit do not cause a change or have an effect upon any other system interface that would result in increasing the likelihood of an accident.

The proposed modification affects the LOVS trip circuit for the Control Room Emergency A/C (CREAC) Units. The LOVS trip circuit logic remains intact, only its initiating device is changed.

The xodification change the initiating device from an auxiliary relay contact in the Containment Dome Air Circulating Fan circuit to the LOVS logic relays directly, located in the 4kV switchgear. Hence for the CREAC unit LOVS trip circuit, the change eliminates an additional circuit component. The modified circuit results in increased reliability of the trip operation by providing a LOVS trip that is independent from the dome fan circuit. The operational design basis of the CREAC unit as explained in the UFSAR Section 9.4.2.2 remains valid. The modification and related installation activities meet the design, material and construction standards applicable to the Class IE electrical equipment being modified. The trip circuit modification does not cause a change to any other system interface that would result in increasing the likelihood of an accident.

Therefore, the proposed activity will not increase the probability of occurrence of an accident previously evaluated in the safety analysis report

2. May the proposed activity increase the consequences of an accident evaluated previously in the safety analysis report?

Response: No.

The Containment Dome Air Circulating Fans and the Containment Emergency Cooling Units operate in conjunction with the containment heat removal system following a design basis accident. There are a total of four dome fans, two fans per safety train. The proposed modifications to the fan units involve only the start circuit clearing function and the inoperable status indication. These two functions play no direct role in mitigating the radiological consequences of an accident. The start signal from the automatic safety function (ESFAS) for a CCAS is not being modified. The inoperable status of the Containment Dome Fans remains C:'NETWP61OCP2,O77O\SECT250WPD

DOCP 2&3-2077.OOSE REV. 0 PAGE 4 i l SECTION 2 - 10CFR50.59 SAFETY EVALUATION governed by SONGS Technical Specification 3.6.8. The proposed modification does not change, degrade or prevent actions described or assumed for an accident previously discussed in the UFSAR.

The Control Room Emergency A/C (CREAC) Unit maintains the control room temperature during emergency operation as described in the UFSAR Section 6.4.4.3. The proposed modification of the trip circuit for the CREAC unit does not affect the automatic safety function (ESFAS) from the Control Room Isolation (CRIS) or Toxic Gas Isolation Actuation (TGIS)

Systems. The LOVS trip function logic remains intact, only its initiating device changes. The LOVS trip circuit is improved by directly utilizing the loss of voltage relays located in the 4kV switchgear, rather than through the use of an auxiliary relay. Control room habitability requirements as indicated in the UFSAR Section 6.4 are fully maintained.

Therefore, the proposed activity will not increase the consequences of an accident previously evaluated in the safety analysis report.

3. May the proposed activity increase the probability of occurrence of a malfunction of equipment important to safety evaluated previously in the safety analysis report?

Response: No.

The proposed modifications for the Containment Dome Air Circulating Fans and the Control Room Emergency A/C (CREAC) Unit will meet the design specification for the material, equipment and construction practices. Seismic and separation criteria are met in performing the required changes to the 4kV switchgear and the 480V loadcenters. Circuits are properly protected by existing knemupting devices. The operation of equipment important to safety is not compromised by this modification. This proposed design change will not adversely affect the capability of the Class 1E electrical switchgear and batteries, nor does it degrade their performance and related safety functions in the mitigation of the accidents and events evaluated in the UFSAR Chapter 15.

For the master Dome Air Circulating Fan, parallel breaker position switches are utilized in the start circuit. This allows the sequence timer to de-energize only when there is a confirmed closure of both master and slave dome fan circuit breakers. This results in a more robust design for the dome fan start circuit, with a decreased likelihood of having a failed start. The additional relay being installed in the master dome fan control circuit plays no direct role in controlling the fan. Its only function is to monitor the loss of control voltage and indicate the condition at the slave fan inoperable status indicating light. The relay is properly protected by an existing control circuit breaker. This design is conservatively judged as being risk neutral.

Based on the proposed modification, the CREAC unit will strip via the 2-out-of-4 LOVS relay logic directly, and not via an auxiliary relay located in the master dome fan circuit. This eliminates a circuit component, makes the two control circuits independent, and results in a more CANETWP61kDCP20707RSECT2BC.WPD

DCP 2&3-2077.OOSE REV. 0 PAGE 56 SECTION 2 - IOCFR50.59 SAFETY EVALUATION simple and reliable design for the CREAC LOVS trip function. This design is conservatively judged as being risk neutral.

Therefore, the proposed activity will not increase the probability of occurrence of a malfunction of equipment important to safety evaluated previously in the safety analysis report.

4. May the proposed activity increase the consequences of a malfunction of equipment important to safety evaluated previously in the safety analysis report?

Response: No.

There are no new consequential effects related to the malfunction of equipment important to safety based on the proposed modification. The operation of equipment important to safety is neither changed nor compromised. The malfunction of the equipment important to safety has been analyzed previously in the UFSAR and its consequences remain unchanged.

Therefore, the proposed modification will not increase the consequences of a malfunction of equipment important to safety previously evaluated in the safety analysis report.

5. May the proposed activity create the possibility of an accident of a different type than any evaluated previously in the safety analysis report?

Response: No.

No new postulated accident is introduced by this proposed modification. The change will not affect the operation of the Class 1E electrical distribution system, the Emergency Diesel Generators or the Class 1E batteries. The 480V breaker for the Control Room Emergency A/C Unit will trip as presently designed, and the design modification will not affect the sequencing of loads onto the Class IE 4.16 kV buses. All control circuit devices are properly protected by existing circuit breaker There ale no reasonable or credible accident or event scenarios potentially associated with the Class 1E electrical distribution system or the Class 1E batteries, affected by this design change, that are different from any of those previously evaluated in the UFSAR Chapter 15.

Therefore, this proposed change will not create the possibility of an accident of a different type than previously evaluated in the safety analysis report.

SECTION 2 - 10CFR50.59 SAFETY EVALUATION

6. May the proposed activity create the possibility of a malfunction of equipment important to safety of a different type than any evaluated previously in the safety analysis report?

Response: No.

No new failure modes are introduced by this proposed modification. New circuits and relays are properly protected by existing circuit breakers. An additional breaker position switch (52b) is being introduced into the master dome fan control circuit from the slave dome fan circuit breaker. The potential circuit failure due to the slave dome fan breaker position switch (52b) being in the incorrect state does not prevent the safety related equipment from starting. Failure modes of the Class IE electrical equipment as shown in the UFSAR Table 8.3-8 remain unchanged.

Therefore, this proposed change will not create the possibility of a malfunction of equipment important to safety of a dierent type than any previously evaluated in the safety analysis report.

7. Does the proposed activity reduce the margin of safety as defined in the basis for any technical specification?

Response: No.

The proposed modification address the start circuit clearing function and the inoperable status alarms for the Containment Dome Fans, and revises the trip scheme for the Control Room A/C Units. This does not specifically impact any part of the technical specifications of SONGS.

However, the modification to the inoperable status indication for the dome fan will provide operators with more realistic alarm condition information for this equipment This will provide a system enhancement to better ensure adherence to Technical Specification 3.6.8. The modification does not change the Emergency Diesel Generator loading nor does it affect the Class lE electrical system. All changes remain within the criteria set forth in the SONGS Technical Specification 3.8. Also, battery load changes as a result of this modification remain within the requirements as explained in the Technical Specification Bases B 3.8.4. The margin of safety for the Class lE batteries is not impacted. The requirements for the batteries' surveillance testing, including the load profile, remain unchanged.

For the master Dome Air Circulating Fan, parallel breaker position switches are utilized in the start circuit. This allows the sequence timer to de-energize only when there is a confirmed closure of both master and slave dome fan circuit breakers. This results in a more robust design for the dome fan start circuit, with a decreased likelihood of having a failed start. The additional relay being installed in the master dome fan control circuit plays no direct role in controlling the fan. Its only function is to monitor the loss of control voltage and indicate the condition at the slave fan inoperable status indicating light. The relay is properly protected by an existing control circuit protective device.

CAtNETWPBI\00P20'7IOSECT2BC.WPO

DCP 2&3-2077.00SE REV. 0 PAGE 52 SECTION 2 - IOCFR50.59 SAFETY EVALUATION Based on the proposed modification, the CREAC unit will strip via the 2-out-of-4 LOVS relay logic directly, and not via an auxiiaiy relay located in the master dome fan circuit. This eliminates a circuit component, makes the two control circuits independent, and results in a more simple design for the CREAC LOVS trip function.

The heat load for the 4kV switchgear room is affected by the additional relays. Specifically, for an SBO event, the GE HMA relay to be installed introduces approximately +3 watts. This is considered negligible and is documented in the appropriate calculations. The existing analyses remain bounding.

Therefore, this proposed change will not reduce the margin of safety as defined in the basis for any technical specification.

SR 3.8.1.18 indicates that every 24 months, it must be verified that for EDG load sequencing the "interval between each sequenced load block is within +/- 10% of design interval for each emergency and shutdown load programmed time interval load sequence". For the existing plant configuration, the ECUs are started at the time = 0 sequence, since their start circuits presently do not include timers. The changes are required due to the condition of having the ECUs sequenced "on" time dependent upon the CCW pump start time. Therefore, the surveillance requirement change included in this DCP indicates that the ECU start time is dependent upon the actual CCW pump start time plus 5 +/-0.5 seconds. This start time tolerance meets the +/-10% interval tolerance requirements of the technical specification. The Technical Specification Bases for 3.8.1.18 will be updated accordingly. This bases change will be in effect only before PCN-454 is approved (see below). This update will be tracked by Site Program Impact AR 961100984 (two assignments, one for each unit).

PCN-454 (Proposed Change NPF-10115454) is an amendment curmntly with the NRC to revise SR 3.8.1.18. The amendment request is to revise the acceptance criteria for the sequence timers from +/-10%

of the time interval to +/-10% of the relay setting or 2.5 seconds, whichever is greater (with the exception of the 5 second load group which is -0.5, +2.5 seconds). PCN-454 adds a new table to the Technical Specification Bases, Table B3.8.1-l DG Load Sequencing Timer Acceptance Criteria. After PCN-454 is approved, the new Table B3.8.1-1 will be updated (if and when this DCP is implemented) in each unit to reflect the impact of this DCP. This update will be tracked by Site Program Impact AR 961100984 (two assignments, one for each unit). Pages labeled " Information Only" are included in this section to indicate the impact this DCP has on PCN-454. This DCP does not depend on or require the approval of PCN-454.

CCW pumps / Containment ECUs fan intejiocks are being added to delay ECUs start time until after CCW pumps started. During a design basis event (when CCAS is present), the ECUs will start 5 seconds after the CCW pumps starts, with or without the LOVS. If the ECU fans are running with a CCAS present and the COCW pump stops, the associated ECU fans will trip. The ECU fans will automatically restart after the CCW pump start if a CCAS is still present. This will ensure that the CCW pump is running before starting the Containment ECU when CCAS is present.

Describe Why Change is Necessary (Attach additional pages as required):

CCW Pumps I Containment ECUs fan interlocks are required In orderto increasing in the Emergency Cooling Units (ECUs). The ECUs start time needs to be the margin to forming steam delayed until after the CCW Pumps started.

The fans and motors are designed to operate sn the containment post-accident environment. The containment emergency fan cooler system is designed in accordance with the codes and standards listed in Appendix 3.2A. Design parameters for the containment emergency fan cooler system are shown in table 6.2-34. The heat removal capability of the containment emergency fan coolers versus containment temperature for the maximum component cooling water inlet temperature is provided by figure 6.2-60.

6.2.2.2.2.3 SVstem 2peration. The containment emergency fan cooler system is an ESF system that is not in use during normal plant operation. system operation is initiated automatically upon sensing high containment pressure or low pressurizer pressure, as discussed in paragraph 7.3.1.1.8.

The containment isolation valves on the component cooling water supply and return lines to the fan coolers are normally open. A Containment Cooling Actuation Signal (CCAS) will open the CCW valve(s) if one or both are closed and start the fans. containme fan cooler system is fully Ioprational with nV4"4peconds, _JThe basis for this time period is give "In table . the emergency cooling mode, once initiated, continues until containment building atmospheric pressure

A. The assumptions concerning the sources and amounts of energy considered and the analyses of the containment pressure transient following a LOCA and a MSLB accident inside the containment are contained in subsection 6.2.1. These analyses show that the containment emergency fan cooler system, in conjunction with the CSS and the shutdown heat exchangers, is capable of removing sufficient heat energy and subsequent decay heat from the containment atmosphere to ensure the accident peak pressure is below the containment design pressure. Accident analyses assume the occurrence of a single failure that results in the loss of one fan cooler train and one containment spray train.

Curves showing sump water temperature, heat generation rates, heat removal rates of the containment emergency fan cooler system, and containment total pressure, vapor pressure, and temperature as a function of time for minimum ESF performance (one fan cooler train and one containment spray train) are given in the figures of subsection 6.2.1. These curves are calculated based on the fan cooler 3/96 6. 2-238 2Revision 11

?he total heat load to the ccw system during normal plant operation _s approximately 40 x 10f Stu/h. The flowrato is approximately 12,000 gal/min.

9.2.2.2.3.3 Plant Cooldown and Shutdown. During plant cooldown and shutdown.

two conponont coolg watier pimps and two ccponent cooeling water beat exchangers are in service supplying cooling water to both critical loops and to the noncritical loop even though only one pump and one heat exchanger are required for safe shutdown.

Plant cooldown and shutdown is Conducted in two phases. The first phase takes place during the first 3-1/2 hours when the reactor coolant is cooled from a hot shutdown tiperatur. of 545-F to 350'! by bleeding steam from the steam generators through the turbine bypass to the condenser. The second phase of shutdown occurs after approximately 3-1/2 hours when the reactor coolant is cooled from 350-F to the refueling temperature within about 27-1/2 hours after 1U shutdown. The two shutdown heat exchangers are placed in service during the second phase to continue plant cooldown and to rmv@ decay heat. The O shutdown heat exchangers maintain the plant at a refualing temperature of 0 appsoiioately 130*? after 27-1/2 hours. During and after the aecond paase of shutdown, the caponent cooling water syst services the shutdown heat exchangers. O NOTE: Initiation of shutdown cooling (SM) at 3.S hours is a plant design feature, not a limiting design basis condition. tnder certain extreme conditions, SW will not be initiated until after 3.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months to maintain Lccvsupply temperature S 105'. operating SDW at 27.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months is also a design feature, not limiting design basis condition. Under extreme conditions, shutdown may require greater than 27.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months to maintain the CCW supply temperature - lOS'1.

Although both shutdown heat exchangers are required to achieve cooldown at this design rate, one shutdown heat exchanger using component cooling water from one critical loop provides cooldown capability, but at a reduced rate.

A local mechanical level indicator is provided on each component cooling water surge tank for safe shutdown in the event of fire when other level indications are lost.

The total heat load and required flowrate for the component cooling water system during plant shutdown is as follows:

Shutdown at 3-1/2 hours: approxlmatly 315 x 1O0 Btulh with two heat exchangers and two pumps operating

Shutdown at 27-1/2 hours: approximatly 230 x 106 Btu/h with two heat exchangers and two pumps operating 9.2.2.2.3.4 Emerornv ti Upon receipt of a CDS. the noncritical loop is isolated from the critical loop by closing the supply and return valves. The noncritical loop containment isolation valves close. The cooling water flow to the spent fuel pool heat exchangers is temporarily interrupted at this time but nay be re-supplied when required by manual alignment of valves. The SIAS ensures the component cooling water pump on each loop is started with Table 8.3-1 time delay to provide cooling to the necessary components.

Yes Section: 3.8.1.1 AND PCN-454 B. DESCRIPTION Summary of Change (Attach additional pages and/or marked up pages as required):

Containment Emergency Cooling Units (ECUs) fan interlocks are being added to delay the start time of the ECUs until after the start of at least one Component Cooling Water (CC" Pump. During a design basis accident with SIASICCAS present, the ECUs will start approximately 5 seconds after the CCW pumps (with or without a loss of voltage signal (LOVS). In addition, the ECUs will stop if there is no CCW pump running, or the running CCW pump has stopped. This change affects the Emergency Diesel Generator (On Site Power) load sequencing as indicated in UFSAR Table 8.3-1.

Describe Why Change is Necessary (Attach additional pages as required):

The interlock and delay functions are required for increasing the design margin to avoid forrning steam.

Currently, this may occur in the ECU coils during a DBA when the ECU fans start prior to the CCW pumps.

The fans and motors are designed to operate in the containment post-accident environment. The containment emergency fan cooler system is designed in accordance with the codes and standards listed in Appendix 3.2A. Design parameters for the containment emergency fan cooler system are shown in table 6.2-34. The heat removal capability of the containment emergency fan coolers versus containment temperature for the maximum component cooling water inlet temperature is provided by figure 6.2-60.

6.2.2.2.2.3 tM. Overation. Th. containment emergency fan cooler system is an ES? system that is not in use during normal plant operation. system operation is initiated automatically upon sensing high containment pressure or low pressurizer pressure, as discussed in paragraph 7.3.1.1.8.

lhe containment isolation valves on the component cooling water supply and return lines to the fan coolers are normally open. A Containment Cooling Actuation Signal (CCAS) will open the CCV valve(s) if one or both are closed and start thefans.$ The emer n fan cooler system Is fully operational withi The basis for this time period is given in table sia e ey cooling mode, once initiated, contiwues until containment building atmospheric pressure reaches 2 lb/in2 g.

A. The assumptions concerning the sources and amounts of energy considered and the analyses of the containment pressure transient following a LOCA and a KnB accident inside the containment are contained in subsection 6.2.1. These analyses show that the containment emergency fan cooler system, in conjunction with the CSS and the shutdown beat exchangers, Is capable of removing sufficient beat energy and subsequent decay heat from the containment atmosphere to ensure the accident peak pressure is below the containment design pressure. Accident analyses assume the occurrence of a single failure that esults in the loss of one fan cooler train and one containment spray train.

Curves showing wip water temperature, beat generation rates, heat removal rates of the containment emergency fan cooler system, and containment total pressure, vapor pressure, and temperature as a function of time for minium ES performance (one fan cooler train and one containment spray train) are given in the figures of subsection 6.2.1. These curves are calculated based on the fan cooler 3/96 6. 2-238 Revision II

Maximum permissible fire loading - 160,00 Note 1: The maximum permissible loading is based on an evenly distributed loading of combustible materials.

Note 2: The quantity of cable insulation -called out above is based on 25%

fill for all cable trays that are filled with cable up to 25% full by volume. For cable trays that are more than 25% full, the actual percentage fill has been used. This is extremely conservative, since very few trays are filled to greater than 25% and the actual plant average tray fill is significantly lower.

Design Basis Fire The design basis fire is postulated to be a fire that reaches a maximum temperature of 1650'F and would involve cable insulation.

The design basis fire is conservatively based on the simultaneous total combustion of all combustibles in the area.

Fire Protection Equipment Manual fire fighting equipment is available within the area and in adjacent area 2-AC-50-29. Ionization smoke detectors, located within the area, provide early warning alarm in the control room.

The Component Cooling lWater System is designed to respond Q; automatically to Engineered Safety Feature Actuation Signals as follows:

.1 SIAS (Safety Injection Actuation Signal) ensures one component cooling water pump on each loop is started.

.2 CIAS (Containment Isolation Actuation Signal) isolates the non-critical loop by closing the supply and return valves to/from both loops, and isolates the cooling supply and return lines to the cooled components located within the 0 Containment. The affected components in the Containment are C served by the non-critical loop and consist of the reactor coolant pump motor and bearing coolers, and the Control Element Drive Mechanism (CEDN) coolers.

.3 CSAS (Containment Spray Actuation Signal) opens the return line stop valves allowing cooling water flow through the shutdown heat exchangers.

0.

.4 CMS (Containment Cooling Actuation-Signal) opens the o component cooling water supply and return lines to the four containment emergency cooling units.

The ECU fans are inteiocked to the CCW pumps. During a design basis event (when CCAS ispruent), the ECUs will star 5 seconds after the CCW pump stas, with or without the LOVS. If a CCW pump fins to start, the associated ECU fr will not start.

(Continued) 2.1.3 General Control Schema (Continued)

.1 (Continued)

The Containment Chilled Water System removes heat from the Normal Cooling Units. During normal operation one Chilled Water Pump is operating and other pump is in standby, one Chiller Unit is operating and the other Chiller Unit is secured. Chiller Unit capacity is maintained in proportion to chilled water load by the Chiller Capacity Control System to maintain the chilled water Dutlet temperature at -43°F.

During normal operations two reactor cavity fans, one Dome Air Circulator and all four Lower Level Circulating fans are operating continuously to provide adequate air circulation and cooling to all regions of conta nment.

During normal operation one CEOM cooling unit Is operating and the second unit is in standby. Each units inlet isolation damper, and Component Cooling Water isolation valves open and close when the unit starts and stops.

The Normal Purge and Recirculation Filtration Subsystem is used to purge containment after shutdown. The Mini-purge system Is used to purge the containment during normal power operations.

The Tendon Gallery Cooling Subsystem is operated continously to allow access into the Tendon Gallery.

.2 CONTAINMENT EMERGENCY VENTILATION SUBSYSTEMS During normal operations one Dome Air Circulator is operating to provide adequate air circulation in the dome. The remaining Dome Air Circulators and the Emergency Cooling Subsystem are not normally operating, but automatically start upon receipt of a Containment Cooling Actuation Signal (CCAS) caused by pressurizer pressure <18O6 psia or containment pressure >2.95 psig.

Component Cooling Water isolation valves to the Emergency Cooling Units open upon receipt of the CCAS signal.

This table indicates the ESFAS response times for major safety related equipment following a postulated design basis accident. The ECU response time is being revised from 21.2 seconds to 47.0 seconds for SIAS from a Pressurizer Pressure Low signal. For SIAS from a Containment Pressure High signal, the ECU response time is changed from 21.0 seconds to 46.8 seconds. There is no change to the LCS bases due to modifications in this DCP.

The response times listed in Section 3.3.100, Table 3.3.100-2 includes only the hardware response time for each ESFAS function. These response times exclude two (2) seconds of time considered in the accident analysis for the containment pressure to reach the analysis high pressure setpoint from occunrence of a design basis LOCA or MSLB event. See Figure 1C in Section 1D.13 of this DCP for details.

3. Memorandum for File dated July 26, 1996, "Plant Protection System Response Time Documents, San Onofre Nuclear Generating Station Units 2 and 3" PURPOSE This Memorandum for File provides a "Supplement A" to Reference I incorporating the response time change for starting the Emergency Cooling Unit (ECU) fans after Safety Injection Actuation Signal (SIAS) / Containment Cooling Actuation Signal (CCAS) actuation APPLICABILITY This Memorandum for File is applicable to San Onofre Nuclear Generating Station Units 2 and 3.

DISCUSSION Reference 2 changes the start time for the Containment Emergency Cooling Unit (ECU) Fans such that the ECU Fans will start running only after the associated Component Cooling Water (CCW) Pump has started. This change will minimize the potential for flashing of the stagnant CCW in the ECU cooling coils prior to CCW flow initiation. Minimizing flashing of CCW within the ECU will minimize the potential for water hammer and subsequent damage to the ECU that would otherwise happen when CCW flow is established through the ECU after a Safety Injection Actuation Signal (SIAS) I Containment Cooling Actuation Signal (CCAS) Post-LOCA or Post-MSLB. The ECU fan start time will be changed from 0.4 seconds after SIAS/CCAS actuation with Offsite Power available or 0.4 seconds after closure of the Emergency Diesel

-0.5 seconds (relay response time) + 0.4 seconds (ECU fan breaker response time) after the associated CCW Pump motor breaker has closed.

In accordance with Reference 3, the new ECU fan time response values will also be incorporated in the applicable DBDs when the revisions to the applicable DBDs are completed to incorporate the first principle document information for Plant Protection System Actuation Response Times.

UFSAR Section 15.1.3.1 Steam System Piping Failures The Main Steam Line Break (MSLB) is classified as a limiting fault and is defined as a pipe break in the Main Steam (MS) System. The conclusions presented in Calculation N-480-007, Revision 2, "Containment Pressure and Temperature from MSLB at Various Power Levels," indicate that the worst case MSLB is a 7.4765 ft2 break area inside Containment while at an initial Reactor Power of 102% and a failure of one train of Containment Emergency Cooling Units (ECUs) and Containment Spray with offsite power available. The mass and energy release data for this worst case MSLB is documented in Combustion Engineering (CE) Letter S-CE-4.007, dated June 29, 1977.

CE Letter S-CE-2604, dated March 1, 1976, states the availability of offsite power permits continued Reactor Coolant Pump (RCP) flow. Maintaining RCP flow maximizes the rate of primary to secondary heat transfer which maximizes the rate of mass/energy release. A MSLB between one of the Main Steam Isolation Valves (MSIVs) and its associated Steam Generator (SG) will result in that SG blowing down to a dryout condition. With a MSLB inside Containment, the affected SG blows down to dryout resulting in Containment pressurization and challenge to Containment integrity.

Calculation N-4080-027, Revision 0, "Containment PIT Analysis for Design Basis MSLB," includes the assumptions stated above. CCN 2 to Calculation N-4080-027, Revision 0, "Containment PST Analysis for Design Basis MSLB - Supplement B," also assumes 7.5% degraded Containment Spray Pumps (1,600 gpm spray flow) and start time of Containment Spray and ECUs delayed to 50 seconds after accident initiation. Note that since Offsite Power is assumed available during this accident, the I0 seconds normally assumed for Emergency Diesel Generator (EDG) startup and output breaker closure is not

D1:Pw2e3-2o7z~tbSe REV ° 1 included in the assumed Containment Spray and ECU stot time. N-4080-027, Revision 0, Supplement B. assumes either a pre-accident Containment pressure of 0.0 psig (14.7 psia) or +1.5 psig (16.2 psia). N4080-027, Revision 0, Supplement B, calculates peak Containment pressure of 56.6 psig and 58.7 psig, respectively. Both calculated peak Containment pressures remain less than the Containment design pressure of 60 psig.

Assuming a pre-accident Containment pressure of either O.0 psig or +1.5 psig and a pre-accident Containment temperature of 120*F, N-4080-027, Revision 0, Supplement B, 427.7 0 F and 421 .60 F, respectively.

calculates peak Contaignent vapor temperatures of Both 427 .7F and 421.6 0 F are greater than the 300'F Containment design temperature, however, the time duration vapor temperature is above 300F is sufficiently brief to prevent heating the Containment structural materials beyond their design limits. Assuming a pre-accident Containment pressure of 0.0 psig instead of +1.5 psig results in a slightly higher short-term peak vapor temperature because the lower Containment air inventory reduces the total Containment heat capacity.

UFSAR Section 15.2 Decrease in Heat Removal by the Secondary System (Turbine Plant)

UPSAR Section 15.2.3.1 Feedwater System Pipe Breaks Feedwater System Pipe Breaks are classified as limiting fault incidents. A Feedwater System Pipe Break may occur due to a pipe failure in the Main Feedwater System (MFW).

A Feedwater System Pipe Break may produce a total loss of normal feedwater and a blowdown of one SG. The Feedwater System Pipe Break event is more severe with a Loss of Normal AC Power (Loss of Offsite Power) because of the loss of forced primary coolant flow, turbine load, Pressurizer (PZR) level and pressure control, and steam bypass control. The culmination of these events is a rapid decrease in the heat transfer capability of both Sss and eventual elimination of one SG's heat transfer capability. The result is a RCS heatup and pressurization.

The Feedwater Line Break event only poses a challenge to Containment Integrity if the pipe break occurs inside Containment. The limiting Feedwater System Pipe Break inside Containment is that which occurs in the Main Feedwater pipeline between the Main Feedwater Check Valve and the SG. This accident will result in blowdown of the SG.

This event is bounded by the MSLB inside Containment. The energy release into Containment for the Feedwater System pipe break from the SG is much smaller than the MSLB because SG inventory spilled into Containment is in the subcooled to saturated liquid state until the SG water level drops below the Main Feedwater inlet to the SO. The enthalpy of the feedwater from the SG is about 530 BtuIlbm, whereas the enthalpy of saturated steam from the SG is about 1196 Btu/lb. (over double the enthalpy of that for the feedwater). After the SG water level drops below the break, then saturated steam is released into Containment.

jcp# 2P3- 2077. o oSE RS O ST 6 UFSAR Section 15.6 Decrease in Reactor Coolant Inventory UFSAR Section 15.6.3.3 Loss of Coolant Accident A Loss of Coolant Accident (LOCA) is considered a limiting fault based upon the expected frequency of occurrence of a LOCA. This UFSAR section covers the spectrum of LOCAs from Small Break to Large Break LOCAs. A failed open PSV is also included in this UFSAR section. The Design Basis LOCA assumes a Loss of Normal AC Power (Loss of Offsite Power) concurrent with the most limiting singe failure which is the failure of one EDG to start on the Loss of Voltage Signal (LOVS).

results in the loss of one train of ECCS, Containment Cooling, The loss of that EDO Containment Spray, and the associated support systems for that train. With only one train of ECCS, Containment Cooling, Containment Spray, etc., available for mitigation of the LOCA, the most limiting radiological releases to the public result.

Calculation N-480-026, Revision 0, "Containment P/T Analysis for Design Basis LOCA" includes the assumptions given above. Calculation N-4080-026, Revision 0, CCN 1, "Containment PYT Analysis for Design Basis LOCA - Supplement assumptions of 7.5% degraded Containment Spray flow and A," also includes the assumes Containment ECU start time consistent wit Containment Spray initiation at 60 seconds after accident initiation. The 60 seconds includes the 10 second EDG startup and time. Calculation N4080-026, Revision 0, Supplement A, performsoutput breaker closure the Containment P/T Analysis assuming either a pre-accident Containment LOCA psig (14.7 psia) or +15 psig (16.2 psia) to demonstrate the pressure of 0.0 peak Post-LOCA Containment Pressure remains below the 60 psig design pressure. The calculated peak Containment pressures are 55.1 psig and 57.0 psig, respectively. Both calculated peak Containment pressures remain below the Containment design pressure of 60 psig. Assuming a pm-accident Containment pressure of either 0.0 psig or +1.5 psig and a Containment pre-accident temperature of 120'F, N-4080-026, Revision 0, Supplement A, calculates peak Containment vapor temperatures of 295.4WF and 294.90 F, respectively, which are bounded by the Containment structural material design temperature of 300F. Assuming a pre-accident Containment pressure of 0.0 psig instead of +

1.5 psig results in a slightly higher short-term peak vapor temperature because the lower Containment ai inventory reduces the total Containment heat capacity.

The analyses of any other high energy, medium energy, or low energy pipe breaks assumed to occur in Containment are bounded by either the Design Basis LOCA or Design Basis MSLB.

Calculation N-4080-003, Revision 5, "Containment Spray (CS) and Emergency Cooling Unit (ECU) Actuation Times," is being revised (ICCN C-1) to change the ECU fan start time from 0.4 seconds after SIAS/CCAS actuation or 0.4 seconds after EDO output breaker closure if Offsite Power is lost to the associated Engineered Safety Features (ESF) bus to 5.0 seconds +2.5 seconds/-0.5 seconds (ECU fan relay response time) ÷0.4 seconds (ECU fan breaker closure time) after associated CCW Pump motor is powered whether Offsite Power is available or is lost. The maximum delay time for ECU fan start time will be 49 seconds after accident/event initiation

D2CP# 2 77.0OSE 03-2 Rw 0 ST /27 which, in accordance with Calculation N-4080-003, Revision 5, ICON C-I, will include the 10 second EDG startup and output breaker closure time following a Loss of Qffsite Power. If Offsite Power remains available, the maximum ECU fan start time will be 39 seconds after accidentlevent initiation. In any case, the ECU fans will start between 4.9 seconds and 7.9 seconds (ECU fan relay time +0.4 seconds for ECU fan breaker closure) after their associated CCW Pump breaker has closed energizing the CCW pump motor. The post accident/event opening time for the Motor Operated CCW Containment Isolation Valves for the ECUs will not be changed. The CCW ECU Isolation Valves will be full open either 12 seconds after SIAS/CCAS actuation or 12 seconds after EDG output breaker is closed assuming SIAS/CCAS actuation with concurrent loss of Offsite Power to the associated ESE bus(es).

1. May the proposed activity increase the probability of occurrence of an accident evaluated previously in the safety analysis report?

Response: No.

The Containment ECUs, in conjunction with the CCW System, are used for the mitigation of accidents/events that result in rising Containment temperature and pressure. This design modification changes the ECU System post-accident response time such that the ECU fans start after the associated CCW Pump is running. This design modification will minimize the potential for CCW system water hammer within the ECU cooling coils.

ECU System response time is only associated with SIAS/CCAS actuation. The ECUs are normally idle during plant operation and start automatically following an accident or event which results in rising containment temperature and pressure. The response time for ECU fan start is not a precursor or initiator of any accident or event previously evaluated in the UFSAR.

Therefore, the proposed activity will not increase the probability of occurrence of an accident previously evaluated in the UPSAR.

2. May the proposed activity increase the consequences of an accident evaluated previously in the safety analysis report?

Response: No.

The Containment ECUs, in conjunction with the CCW System, are used for the mitigation of accidents/events that result in rising Containment temperature and pressure. The design basis of the ECU is the mitigation of the Large Break LOCA (Reactor Coolant System Cold Leg break) inside Containment with concurrent Loss of Offsite Power and assumed single failure rendering one Containment Cooling train unavailable and the mitigation of a MSLB inside Containment with Offsite Power available and assumed single failure rendering one Containment Cooling train unavailable. This design modification changes the ECU System post-accident response time such that the ECU fans start only after the

DM42,f3-207R V0 sH associated CCW Pump is running. This modification will minimize the potential for CCW system water hammer within the ECU cooling coils. ECU System response time is associated with actuation upon receipt of a SIAS/CCAS actuation.

Calculation N-4080-026, Revision 0, Supplement A has evaluated the LOCA response assuming availability of only one train Containment Spray and one train of ECUs with concurrent loss of Offsite Power. This calculation assumes the ECUs begin operating at 60 seconds Post-LOCA. The actual maximum setting for ECU fan start time is +7.9 seconds after associated CCW Pump start time (+7.5 seconds for ECU fan relay response and +0.4 seconds for ECU fan breaker closure) or about 49 seconds Post-LOCA initiation. Therefore, the ECU fan start time is 11 seconds sooner than the start time assumed in the Design Basis Analysis of Record for LOCA in Calculation N-4080-026, Revision 0, Supplement A and is bounded.

Calculation N-4060-008, Revision 4, "Post-LOCA Containment Leakage Doses to EAB LPZ," calculates total Post-LOCA dose at the Exclusion Area Boundary and the Low Population Zone based upon an assumed Design Basis LOCA inside Containment with Loss of Offsite Power and assumed single failure rendering one tain of Containment Spray and ECUs unavailable. This calculation assumes Contaiment leakage rates based on Regulatory Guide 1.4 which requires the use of the maximum leak rate allowed by Technical Specification (TS) Limiting Condition for Operation (LCO) 3.6.1 (the Containment leakage rate is established by I0CFR50, Appendix J, modified by approved exemptions). This calculation assumes the initiation of the available train of Containment Spray and ECMs at 1 minute (60 seconds) Post-LOCA. Therefore, the ECU fan start time is 11 seconds sooner than the start time assumed in the Design Basis Analysis of Record for LOCA offsite dose due to release of radioactivity from Containment provided by Calculation N-4060-008, Revision 4 and is bounded. The analysis of record for the Offsite Dose consequences of a MSLB inside Containment is Asea Brown Boveri (ABB)

Design Analysis A-SG2-FE-0100, Revision 00, "SONGS-2 Cycle 9 RAR Dose Assessment." This calculation does not use Containment Spray or ECU initiation as input parameters to the analysis, therefore, the MSLB inside Containment Offsite Dose analysis is unaffected by this design modification. Therefore, this modification does not increase the Offsite Dose for the Design Basis LOCA or Design Basis MSLB inside Containment and the release of radioactivity to the public is not increased.

Calculation N-4080-027, Revision 0, Supplement B has evaluated the MSLB response assuming only one train Containment Spray and one train of ECUs with Offsite Power available. With Offste Power remaining available, all four RCPs are assumed to remain running which results in a greater energy release into Containment. This calculation assumes the ECUs begin operating at 50 seconds Post-MSLB because EDG startup and breaker closure time is excluded. The actual maximum setting for ECU fan start time is

+7.9 seconds after associated CCW Pump start time (+7.5 seconds for ECU fan relay response and +0.4 seconds for ECU fan breaker closure) or about 39 seconds Post-MSLB initiation. Therefore, the ECU fan start time is 11 seconds sooner than the start time

When CCW flow is established, the steam trapped in the ECU cooling coils could cause water hammer and damage cooling coils. This issue was not previously addressed in the UFSAR. This design modification is a corrective action as directed by Action Request (AR) 960801324.

aZf 3 - 077. OOSE 2 °R s J 30 (ECU fan breaker closure time) after CCW Pump start does not alter the function or capability of the ECU. Delaying the ECU fan start until after CCW Pump is running does not reduce the heat removal capability of the ECU. This design modification will slightly increase the overall response time of the Containment Emergency CoQingWystemto a SIAS/CCAS actuation signal. The delayed starting time for the ECU fans remains within the bounds of the applicable analyses of record for the design basis LOCA and design basis MSLB as noted in the response to IOCFR50.59 Question 2, above. However, the design basis assumptions for the analyses of record for LOCA and MSLB are not compromised by this modification.

The delayed start of the ECU fans has been analyzed and does not compromise the safety function of the Class 1E electrical distribution system, the EDGs, or the Class 1I batteries, nor does it reduce their margin of safety. The 5 second delay timer with a tolerance of + 0.5 seconds meets the requirements of SONGS TS Surveillance Requirement (SR) 3.8.1.18 ( 10% of design interval) forEDG load sequencing. This modification also meets the requirements of proposed TS change PCN-454 which requests a change to the tolerance of sequenced loads to either +10% of the timer setting or +/-2.5 seconds of the timer setting, whichever is greater with the exception of the 5 second time delay relay which has a tolerance of +2.5 seconds/-0.5 seconds.

This design modification will meet the design specifications for the material, equipment, and construction practices. This design modification does not affect any other ECU, CCW, or Containment system operations, interactions, or functions. Seismic Category I specifications and separation criteria for redundant safety related equipment are maintained by this design modification for changes implemented to Class IE 4.16kV switchgear or 480V loadcenters. Each train of ECUs and CCW Systems remains separate and redundant. This design modification does not introduce any common failure modes to the ECU Systems, CCW Systems, or their associated control circuits. Single failure criterion requirements are maintainedL The added relays are identical to a type of relay already utilized in this equipment and circuits are properly protected by interrpting devices. The additional Class IE battery loading associated with the additional relays has been analyzed and remains bounded by the battery loading analyses. Therefore, this design modification does not adversely affect the capability or function of the Class IE 4.16kV and the 480V electrical distribution subsystems or the Class 1E batteries. This design modification does not degrade the performance of this equipment and their related safety functions for the mitigation of any of the accidents or events previously evaluated in the UFSAR.

The UFSAR safety evaluations are based upon control circuits as a whole, independent of the number of devices in a specific circuit. Therefore, installing additional devices to the existing ECU fan control system would have no impact on its previoulsy evaluated probability of failure.

Therefore, the proposed modification will not increase the probability of occurrence of a malfunction of equipment important to safety previously evaluated in the UFSAR.

that the This design modification changes the ECU fan start time and trip circuits to assure a design basis LOCA or MSLB inside CCW pump is running prior to ECU fan start during Containment. This design modification also ensures the ECU fan trips if its associated time to CCW pump trips with a SIAS/CCAS signal present. Delaying the ECU fan start after the CCW Pump start time allows the forced CCW circulation through the ECU cooling coils prior to establishing forced flow of the high temperature Containment atmosphere through the ECU and prevent water hammer from occurring in the ECU cooling coils. This design modification will not compromise the assumptions used in the analyses of record for the design basis LOCA or design basis MSLB.

This design modification does not affect any other ECU, CCW, or Containment system operations, interactions, or functions. Each train of ECUs and CCW Systems remains failure separate and redundant. This design modification does not introduce any common requirements are modes to the ECU Systems or control circuits. Single failure criterion are maintained. The failure modes and effects analyses for the ECUs and the CCW system or not altered by this modification. The consequences of previously analyzed failures malfunctions of equipment important to safety are not altered by this design modification.

The consequences of a malfunction of equipment to safety previously evaluated in the UFSAR were based upon an ECU start time of 60 seconds post-accident. The maximum actual start time for the ECU is 49 seconds assuming a Loss ofQffsite Power, hence, the modified ECU fan starting circuit function is bounded by the previous anaysis.

Therefore, the proposed modification will not increase the consequences of a malfunction of equipment important to safety previously evaluated in the UFSAR.

5. May the proposed activity create the possibility of an accident of a different type than any evaluated previously in the safety analysis report?

Response: No.

the This design modification changes the ECU fan start time and trip circuits to assure that LOCA or CCW pump is in operation or starts prior to ECU fan start during a design basis MSLB inside Containment. This design modification also ensures the ECU fan trips if its associated CCW pump trips.

6. May the proposed activity create the possibility of a maunction of equipment important to safety of a different type than any evaluated previously in the safety analysis report?

Response: No.

This design modification changes the ECU fan start time and trip circuits to assure that the CCW pump is nunning prior to ECU fan start during a design basis LOCA or MSLB inside Containment. This design modification also ensures the ECU fan trips if its associated CCW pump trips. Delaying the ECU fan start time to after the CCW Pump start time allows the forced CCW circulation through the ECU cooling coils prior to establishing forced flow of the high temperature Containment atmosphere through the ECU and prevent water hammer from occurring in the ECU cooling coils. This method of operation of the ECIJs Post-LOCA or Post-MSLB after this design modification ensures the CCW system and the ECUs will perform as designed. All previously analyzed Failure Modes and Effects analyses remain unchanged by this design modification. Although ECU fan start will be tied to associated CCW Pump start rather than directly after SIAS/CCAS, any consequences of an ECU fan failure remain unchanged from the previous UFSAR analysis.

There are no new component or system failure modes created by this design modification.

The UFSAR safety evaluations are baseu upon control circuits as a whole, independent of the number of devices in a specific circuit. Therefore, installing additional devices to the existing ECU fan control system would have no impact on its previoulsy evaluated probability of failure.

No new electrical system failure modes are introduced by this design modification. New circuits and relays are properly protected by existing circuit breakers. Failure modes of the Class IE electrical equipment provided in UFSAR Table 8.3-8 remain unchanged.

There are no reasonable or credible alternative failure modes associated with the lE Electrical Distribution subsystems, the CCW System, or the Containment ECUs affected by this design change that could result in a maifunction of equipment important to safety different than any previously analyzed in the UFSAR. Therefore, this proposed change will not create the possibility of a malfunction of equipment important to safety of a different type than any previously evaluated in the UFSAR.

The Containment Spray System and Containment Cooling System limit g1kft~erature and pressure that could be experienced following a Design Basis Accident (DBA). The limiting DBAs considered relative to containment temperature and pressure are the LOCA and MSLB. The DBA LOCA and MSLB are analyzed using computer codes designed to predict the resultant Containment pressure and temperature transients. No DBAs are assumed to occur simultaneously or consecutively. The postulated DBAs are analyzed with regard to containment ESF systems, assuming the loss of one ESF bus, which is the worst case single active failure, resulting in one train of the Containment Spray System and one train of the Containment Cooling System being rendered inoperable.

TS 3.6.6.2, "Containment Cooling Systems," Mode 4, requires that two Containment Cooling trains shall be OPERABLE. The Containment Cooling System limits the temperature and pressure that could be experienced following a DBA.

The DBA LOCA and MSLB are analyzed using computer codes designed to predict the resultant Containment pressure and temperature transients. No DBAs are assumed to occur simultaneously or consecutively. The postulated DBAs are analyzed with regard to Containment ESF systems, assuming the loss of one ESF bus, which is the worst case single active failure, resulting in one train of the Containment Cooling System being rendered inoperable. Note that in Mode 4, the stored energy in the Reactor Coolant System (RCS) and the Steam Generators is much lower than when operating in Modes 1, 2, or 3, therefore, unlike TS 3.6.6.1, only the Containment Cooling System is required to be OPERABLE.

This prevents the Containment sump fluid from increasing in temperature during the recirculation phase following a LOCA, and provides a gradual reduction in the temperature of this fluid as it is supplied to the RCS by the Safety Injection Pumps. The CCW System is designed to perform its function with a single failure of any active component, assuming a Loss of Offsite Power.

T his design modification is also in compliance with the proposed new basis for SR3.8.1.18 incliided inPCN.-454. Thus, it is assured that EDG loading will not be overburdened to the point which would degrade its performance, or jeopardize its capability to achieve its designed safety function. With implementation of this design modification, the ECU sequenced start time is dependent upon the CCW pump's start time. The safety margin of the EDG is neither reduced nor compromised based on the delayed start of the ECU. This is because the worst case load sequencing time for the EDO is at breaker closure (sequence time t = 0). In addition, the margin of safety for the Class IE batteries is not impacted. The battery load changes, based on this design modification, do not occur at the most limiting period of the battery load profile.

The battery load profile, available design margin and required surveillance test loading remain intact. Thus, the capability of the EDGs and Class IE batteries to perform their required safety functions is fully maintained. For a design basis accident scenario, existing calculations for the switchgear room remain bounding for the added heat load from the two Agastat relays in the 4.16 kV switchgear.

Calculation N-4080-026, Revision 0, Supplement A has evaluated the LOCA response assuming availability of only one train Containment Spray and one train of ECUs with concurrent loss of Offsite Power. This calculation assumes the ECUs begin operating at 60 seconds Post-LOCA. The actual maximum setting for ECU fan start time is +7.9 seconds after associated CCW Pump start time (+7.5 seconds for relay response and +0.4 seconds for ECU breaker closure) or about 49 seconds Post-LOCA initiation. Therefore, the ECU fan start time is 11 seconds sooner than the start time assumed in the Design Basis Analysis of Record for LOCA in Calculation N-4080-026, Revision 0, Supplement A and is bounded.

Calculation N-4060-008, Revision 4, 'Post-LOCA Containment Leakage Doses to EAB LPZ," calculates total Post-LOCA dose at the Exclusion Area Boundary and the Low Population Zone based upon an assumed Design Basis LOCA inside Containment with Loss of Offsite Power and assumed single failure rendering one train of Containment Spray and ECE~s unavailable. This calculation assumes Containment leakage rates based on Regulatory Guide l4 which requires the use of the maximum leak rate allowed by Technical Specification (TS) Limiting Condition for Operation (LCO) 3.6.1 (the Containment leakage rate is established by IOCFR5O, Appendix J, modified by approved exemptions). This calculation assumes the initiation of the available train of Containment Spray and ECUs at 1 minute (60 seconds) Post-LOCA. Therefore, the ECU fan start time is 1 seconds sooner than the start time assumed in the Design Basis Analysis of Record for LOCA offsite dose due to release of radioactivity from Containment provided by Calculation N-4060-008, Revision 4 and is bounded. The analysis of record for the Offsite Dose consequences of a MSLB inside Containment is Asea Brown Boven (ABB)

Design Analysis A-SG2-FE- 100, Revision 00, "SONGS-2 Cycle 9 RAR Dose Assessment." This calculation does not use Containment Spray or ECU initiation as input parameters to the analysis, therefore, the MSLB inside Containment Offsite Dose analysis

DC.PE 2X3-2,77.00E REV 0 SH4T 13 is unaffected by this design modification. Therefore, this modification does not increase the Offsite Dose for the Design Basis LOCA or Design Basis MSLB inside Containment and the release of radioactivity to the public is not increased.

Calculation N-4080-027, Revision 0, Supplement B has evaluated the MSLB response assuming only one train Containment Spray and one train of ECUs with Offsite Power available. With Offsite Power remaining available, all four RCPs are assumed to remain running which results in a greater energy release into Containment. This calculation assumes the ECUs begin operating at 50 seconds Post-MSLB because EDG startup and breaker closure time is excluded. The actual maximum setting for ECU fan start time is

+7.9 seconds after associated CCW Pump start time (+7.5 seconds for relay response and

+0.4 seconds for ECU fan breaker closure) or about 39 seconds Post-MSLB initiation.

Therefore, the ECU fan start time is 11 seconds sooner than the start time assumed in the Design Basis Analysis of Record for MSLB in Calculation N-4080-027, Revision 0, Supplement B and is bounded.

LCS 3.3.100 Table 3.3.100-2, "ESF Response Times," Item 2.a.(5)(c), response time for ECU Fans to a SIASICCAS actuaion on Pressurizer Pressure -Low condition is being changed from 21.2 seconds to 47.0 seconds; and, Item 3.a.(4)(c), response time for ECU Fans to a SIASICCAS actuation on Containment Pressure -High is being changed from 21.0 seconds to 46.8 seconds. These changes to LCS 3.3.100 are being implemented by DCP 2&3-2077.OOSE. The new response time settings remain conservative to the assumed start time for the ECU fans post-accident analyses of record as noted above and the margin of safety provided by the basis for LCS 3.3.100 is not compromised by this change.

All other high energy, medium energy, or low energy pipe breaks in the Containment are bounded by either the LOCA or MSLB accidents inside Containment and mitigation of these accidents/events is accomplished by one train of two ECUs and one Containment Spray train when the unit is operating in either Mode 1, 2, or 3 or by one train of two ECUs in Mode 4, only. The Containment ECUs are not required for mitigation of any pipe breaks outside Containment or any other assumed events.

When the unit is operated in either Mode 1, 2, 3, or 4, two trains of two ECUs, each, must be operable and available for accident mitigation (reference 10CFR50.59 Question 7 response). Each train of ECUs is independently capable of performing the required safety functions. This design modification does not introduce any new common failure modes.

The single failure criterion requires that an accident mitigation system must be able to perform its safety function assuming the worst case possible single failure. Assuming occurrence of an accident/event requiring ECU operation, at least one train of ECUs will be functional and capable of performing the required safety functions should an assumed single failure render the other train unavailable. The single failure criterion will not be affected by this design modification.

Therefore, this proposed change will not reduce the margin of safety as defined in the 1DCP, ZPt.. - 2 077, =0osE~REV SH 3 Therefore, this proposed change will not reduce the margin of safety as defined in the basis for any technical specification.
