DESCRIPTION AND SAFETY ANALYSIS OF PROPOSED CNANGE NUMBER NPF-10/15-470 Proposed Change Number 470 is a request to_ revise Technical Specification (TS) 3.4.9,-" Pressurizer," for San Onofre Nuclear Generating Station (SONGS)
Units 2 and 3.
EXISTING TECHNICAL SPECIFICATIONS AND BASES Unit 2:- See Attachment 1 Unit 3: See Attachment 2 PROPOSED TECHNICAL SPECIFICATIONS AND BASES Unit 2: See Attachment 3 Unit 3: See Attachment 4 UPDATED FINAL SAFETY ANALYSIS REPORT (UFSAR) CHAPTER 15 SAFETY ANALYSIS Units 2 and 3 See Attachment 5 DESCRIPTION OF CHANGE This proposed change is a request to revise the allowed water level for pressurizer operability in both the Technical Specification 3.4.9 Limiting Condition for Operation (LCO) and Surveillance Requirement (SR) 3.4.9.1. The proposed allowed level for pressurizer operability is requested to be reduced to less than or equal to 57%. Technical Specification 3.4.9 currently requires the water volume to be less than or equal-to 900 ft (whichis 3
approximately 60% pressurizer level).
From certain safety analyses that were performed to support this reduction in pressurizer level it was determined that operator action time needed to be reduced from 30 minutes to 15 minutes to mitigate two types of events. These analyses are for Chemical Volume and Control System (CVCS) Malfunction and Inadvertent Emergency Core Cooling System (ECCS) Actuation During Power Operation. The adequacy of 15 minutes operator action time-has been demonstrated by SONGS operators. Early operator recognition and actions to mitigate pressurizer overfill events within approximately 5 minutes have been demonstrated by operator. response experience on the SONGS 2 and 3 simulator and also in: actual plant operating conditions. Additionally, the availability of operator alarms and indications in the SONGS control room further support the adequacy of this reduced operator action time. Two other events in the Updated Final Safety Analysis Report (UFSAR) Chapter 15 Safety Analyses take
. t credit for operator action in less than 30 minutes. lThese events are Dropped .;
Control Element Assembly (CEA)-and Boron Dilution; both credit operation action to mitigate the event within~15 minutes. -
- For information only, Technical Specification Bases 3.4.9.is to be revised to reflect a less than or equal to 57% Pressurizer level and to correct the l Background text by revising "2750 psig to "2750 psia."
Also for information, this' proposed change includes results-of the reanalysis of certain UFSAR Chapter 15 safety analysis events that are sensitive to pressurizer level (See attachment 5).
DISCUSSION i - A. Background
--The control room indicated pressurizer level indication Total Loop Uncertainty (TLU)wasrecalculatedaspartofaSouthernCaliforniaEdison(SCE) program to evaluate instrument loop uncertainties in instruments used for Technical Specification Surve111ances. This TLU calculation was performed using the
~
current instrument accuracy calculation methodology developed by SCE as part ,
of the TLU program. The recalculation yielded a control room indicated -
pressurizer level maximum TLU value of 3.9%. Incorporation of this TLt' value requires restricting Pressurizer Level to 57% (i.e., approximately 860 ft ),
3 which is less than the current Technical Specification 3.4.9 value of 900 ft'.
UFSAR Chanter 15 events that are sensitive to Pressurizer water volume were reanalyzed to accommodate the 3.9% TLU by assuming a bounding 4.0% TLU. The events are the Chemical and Volume Control System (CVCS) Malfunction with and
, without Concurrent Single Failure of an Active Component (UFSAR Sections.
15.5.2.1and15.5.1.1),InadvertentOperationoftheEmergencyCoreCooling
- System (ECCS)duringPowerOperation(UFSARSection15.5.1.2),andFeedwater 4-Systein Pipe Breaks (UFSAR Section 15.2.3.1). Additionally, " Inadvertent Operation of the ECCS During Power Operation was analyzed with concurrent single failure of an active component." The results of this analysis, which are bounded by the results of a Chemical and Volume Control System (CVCS)
M* .~ unction, will be added to the UFSAR as Section 15.5.2.2.

- The reanalysis of these events was performed using the approved CESEC-III computer code. The analytical value assumed for pressurizer level was 61%
-(i.e...theproposed57%TechnicalSpecificationvalue.andupto4.0%TLU).
.The results of the reanelyses are summarized as follows:
- 1. UFSAR Section 15.5.1.1, Chemical and Volume Control System -
Malfunction Summary of Analysis The CVCS' malfunction is classified as a moderate frequency event. The initiating malfunction is a failure of the pressurizer level control system which could initiate operation of all 3 charging pumps and' isolate letdown. Depending on the failure mode the pressurizer level control system may not automatically terminate the event, so that operator action would be required. Various pressurizer level and pressure control indications and alarms are available to alert the
- -operator of the event. Operator action within 15 minutes to correct the additional charging f'ow will terminate this event prior to filling the pressurizer. The operator action tir
- for this event was previously 30 minutes.
In order to support a reduction of the operator action time required for this event from 30 minutes to 15 min'utes SCE performed a simulation of this event on the Full Scope Simulator. Operators recognized and terminated this event on the Simulator in approximately 5 minutes.
Operator simulator training and available alarms and indications in the control room support early operator recognition. It is also important to note that the CVCS malfunction event occurred at SONGS Unit 3 on March 2, 1995. For this_ case operator action was implemented within approximately 5 minutes which terminated the event, demonstrating that an operator response time of 15 minutes can be accommodated.
2.- UFSAR Section 15.5.2.1 Chemical and Volume Control System Malfunction with a Concurrent Single Failure of an Active Component Summary of Analysis The CVCS malfunction with a single failure-is classif15d as an infrequent event. The results are similar to those discussed in Item 1 above with'the exception of the. single failure. The worst case single

Power Operation i Sumary of Analysis -
An inadvertent operation'of the ECCS is classified as a moderate-frequency event. The . initiating cause is an unplanned increase. in:
reactor coolant: inventory due to operator error that. erroneously _
~
actuates a safety: injection actuation signal- (SIAS). The inadvertent -
-SIAS' activates all three charging pumps, isolates letdown-flow, starts.
theboricacidmakeup(BAMU)-pumps, shifts.chargingpumpsuctiontothe highly borated BAMU tanks, starts the. safety injection pumps, and isolates instrument air to containment. The boration causes a reduction- -
- in Reactor Coolant. System (RCS) temperature and associated shrinkage in pressurizer-liquid volume, which partially mitigates the excess charging
' flow. A reactor. trip eventually-occurs on high pressurizer-pressure or on low steam generator pressure during the plant cooldown. As a result of the boration af the RCS, the consequences of this event are less 4
adverse than the CVCS malfunction event described in UFSAR Section 15.5.1.1 and there is at least as much time for operator' action as in the CVCS malfunction event. Therefore, there is at least 15 minutes for the operator-to correct the malfunction and prevent filling of the .
Pressurizer..
- 4. UFSAR Section 15.5.2.2 Inadvertent _0peration of.the ECCS During Power Operation with a Concurrent Single Failure of an Active Component Sumary of' Analysis The inadvertent Operation ~of the ECCS with a single failure is classified as aniinfrequent event. The results are similar to those discussed in Item 3 above with the exception of the single failure.- The
.worst-case single failure postulated for this event is the loss of-F
- offsite' power at the time of reactor trip. ' As a result of the boration t of the RCS, there is at-least as much time for operator action as-in the CVCS malfunction with conctrrent single failure event described _in UFSAR.

Pressurizer.
- 5. UFSAR Section 15.2.3.1, Feedwater System Pipe Breaks 1m atry of Analysis Thr. feedwater system pipe break is classified as a limiting fault . event.
The initiating event is a break in a pipe in the main feedwater system.
- A rupture of a feed line will.cause rapid reduction of the liquid inventory in the affected steam generator and therefore create a partial loss of the secondary heat sink. This leads to heatup of the RCS and an increase in RCS-pressure. A reactor trip could occur through either a low Steam Generator Water Level Trip, a low Steam Generator Pressure Trip, or a High Pressurizer Pressure Trip. Loss of non-emergency AC power was assumed at the time of reactor trip.
Operator action to mitigate the event is assumed to occur 30 minutes after initiation of the event. Peak RCS pressure will remain below the acceptance criteria of 120%.of design pressure, and no water will be released through the pressurizer safety valves for the maximum RCS pressure case.
C. Plant Operation Accounting for the pressurizer level control room indication TLU of 3.9%
(boundingsafetyanalysisvalueof4.0%)intheTechnicalSpecification effectively lowers the allowed pressurizer level for operability. Currently, i the Technical Specifications specify a level for operation at less than or equal to 900 cubic feet (which corresponds to approximately 60% level). With
-a TLU value of 4.0%, the Technical Specification control room indicator value needs to be reduced to 57% to be consistent ~f t'i the safety analyses which were done at 61% pressurizer level. The norni full power pressurizer level for plant operation is approximately 53%. Administrative controls have been implemented to ensure that the pressurizer level does not exceed 57% during operation. SCE has determined that steady state pressurizer operation above 57% during power operation has not occurred.
SAFETY ANALYSIS
- 1. Will operation of the facility in accordance with this proposed change involve a significant increase in the probability ur consequences of any accident previously evaluated?
Response: No The limiting events impacted by this Technical Specification change have been reanalyzed. These events are the Chemical and Volume Control System (CVCS) Halfunction and CVCS Malfunction With a Concurrent Single Failure of an Active Component, Inadvertent Operation of the Emergency Core Cooling System (ECCS) During Power Operation (Including Single Failure of an Active Component), and Feedwater System Pipe Breaks. The probability of these events is not changed by the restriction of the pressurizer level to 57%. An operator action time of 15 minutes has been identified for the CVCS nialfunction and inadvertent ECCS operation events. Based on the availability of operator alarms and indications and operator Simulator training, 15 minute operator action is sufficient to recognize and mitigate the inadvertent CVCS or ECCS operation.
Therefore, this change will not involve an increase in the probability or consequences of any previously evaluated accident.
- 2. Will operation of the facility in accordance with this proposed change create the possibility of new or different kind of .ccident from any previously evaluated?
Response: No This amendment request does not involve any change to plant equipment or operation. All the events identified in Chapter 15 of the Updated Final SafetyrealysisRepcrt(UFSAR)wereevaluatedtodeterminetheimpactof the cham in pressurizer level. In addition to the normally analyzed Inadvertent Operation of the ECCS During Power Operation event a concurrent single failure of an active component was considered in this evaluation. The analysis of this event with single failure of an active component produced consequences that are bounded by the CVCS malfunction with 31ngle failure of an active component. No new or different kind of accident wl11 be created as a result of this Technical Specification change. Therefore, this change does not create the possibility of a new or different kind of accident from any previously evaluated.
