Design Basis Dose Consequences and Recirculation Loop Margin Leakaa-e Rates Revision 0: Issued 2004 Revision 1:

Issued in 2008 as requested in AR A0725926 to be consistent with the FSARU discussion (Reference 12.a.4, Sections 3.1.1.1 and 6.3A.3) regarding the passive failure of the RHR pump seal occurring at 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after the start of the accident. Revision 0 assumes that the failure occurs at 23.7 minutes after LOCA initiation. The Revision 1 assumption of a passive leak at 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> is consistent with the NRC Standard Review Plan Section 15.6.5.B.

Revision 2:

The calculation is revised to increase the assumed containment spray delay time from 86.5 seconds to 106 seconds and to increase the assumed times to close control room dampers from 10 seconds at both units to 18 seconds at the unaffected unit and 44.2 seconds at the unit undergoing a Loss of Coolant Accident (LOCA). The increase is due to changes in the Emergency Safeguards Features (ESF) actuation delay times resulting from resolution of the 230kV degraded voltage issue (Reference 12.a.24). A spray delay of 106 seconds and the assumed damper closure times bound the maximum potential delays associated with resolution of this issue and include the limiting delays for LOCA initiation to Safety Injection (SI) signal generation/ actuation. This calculation evaluates only the radiological impact of the increased ESF delay and response times, not other potential impacts of the delay.

While preparing this revision, the need was recognized to use a more conservative spray iodine removal rate (Reference 12.a.27), a more conservative control room air flow rate (Reference 12.a.20),

a more conservative control room inleakage rate, and a more conservative distance to the Low Population Zone (LPZ) boundary (Reference 12.a.28). This revision includes these conservative inputs.

Revision 2 is issued 9/2011 pending implementation and will be issued final upon receipt of the License Amendment for License Amendment Request 11-06, PG&E Letter DCL-1 1-072.

Since the revision includes a change to current format, it is a full revision per CF3.1D4 5.7.2.a.1 and does not contain revision bars.

Purpose:

This design calculation evaluates the design basis control room and offsite dose consequences, and establishes the limiting margin leakage rates from post-LOCA recirculation loop components outside containment. This calculation supersedes PG&E Calculations N-167, STA-090 and STA-087. This calculation also evaluates the control room post accident dose consequences of the closure times of the control room ventilation system (CRVS) outside air isolation dampers, and provides the basis for the allowable closure times of these dampers.

2.

Background:

Calculation N-167 Revision 0 (Reference 12.a.1) was issued in 1994 to document the design basis (loss of coolant accident [LOCA]) control room and offsite doses from all leakage pathways. These include containment leakage, RHR pump seal leakage, and expected post-LOCA recirculation loop leakage. Calculation N-167 also determines various control room and offsite doses for a one-gpm recirculation loop leak.

Due to an increase in the assumed containment spray actuation delay time, Calculation STA-087 Revision 0 (Reference 12.a.2) was issued in 1998 to document the resultant change in control room and offsite dose consequences due to containment leakage. Since the spray delay time change did not impact the N-167 doses for RHR pump seal leakage and expected post-LOCA recirculation loop leakage, these values were used as-is in STA-087.

Calculation STA-090 Revision 0 (Reference 12.a.3) was issued in 1998 to determine the limiting margin leakage rate from post-LOCA recirculation loop components outside containment. The margin leakage rate is defined as the amount of leakage in excess of the expected leakage from recirculation loop components outside containment, whose dose consequences, when combined with the dose consequences from containment leakage and RHR pump seal leakage, will not exceed 10 CFR 100 and 10 CFR 50, General Design Criteria (GDC) 19 dose limits.

Prior to the issuance of STA-195 Revision 0, Section 9.4.1.2 of the FSARU (Reference 12.a.26) stated that the control room ventilation system outside air isolation dampers require about five seconds to close upon initiation of CRVS Modes 3 or 4. The source/basis for this closure time could not be determined. Since this damper closure time was sometimes difficult to achieve, AR A0528956 was initiated in April 2001 to request an evaluation of an acceptable tolerance band for this closure time. Revision 0 of this calculation, issued in 2004, provided the support for a 10-second allowable closure time which is reflected in the current FSAR (Reference 12.a.4, Section 9.4.1.3.7.2).

STA-087 Revision 1 (Reference 12.a.5) was issued to correct an input error that resulted in "double counting" a portion of the calculated dose totals. This error correction, along with increasing the CRVS outside air isolation damper closure time, results in changes to the design basis control room dose due to containment leakage. Since this change to the containment leakage dose component impacts STA-090 and impacts the dose calculations of N-167 that assume nominal control room infiltration, STA-195 Revision 0 superseded both of these calculations.

DCPP Form 69-20428 (04107110) CF3.1D4 Attachment 6 Design Calculation Page 4 of 226 DCA 90000019634 Part 002 Vs 00 (Legacy No. STA-195)

STA-195 Revision 1 was issued in 2008 as requested in AR A0725926 to be consistent with the FSARU discussion (Reference 12.a.4, Sections 3.1.1.1 and 6.3A.3) regarding the passive failure of the RHR pump seal occurring at 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after the start of the accident. Revision 0 assumes that the failure occurs at 23.7 minutes after LOCA initiation. The Revision 1 assumption of a passive leak at 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> is consistent with the NRC Standard Review Plan Section 15.6.5.B (Reference 12.a.19).

STA-195 is revised in Revision 2 to increase the assumed containment spray time delay from 86.5 seconds to 106 seconds. The additional assumed delay in CS delivery time is being assumed in the calculation to bound the maximum potential delay associated with resolution of the 230 kV degraded voltage issue described in SAP Notification 50301167. An additional six second delay from LOCA initiation to SI signal generation is included to provide consistency with the approach for determining the maximum overall containment spray delay time.

STA-195 Revision 2 also increases the control room damper closures from 10 seconds for both units to 18 seconds (non-LOCA unit) and 44.2 seconds (LOCA unit). These additional delays in CRVS inlet damper closure times are being assumed in the calculation to bound the maximum potential delays associated with resolution of the 230 kV degraded voltage issue described in SAP Notification 50301167, and to account for the limiting LOCA initiation to SI actuation time delay.

This revision evaluates only the radiological impact of the increased spray delay time, and not any other potential consequence of the increased spray delay time. Finally, this revision supersedes Calculation STA-087 since it changes the containment release doses based on the increased ESF delay and response times.

While preparing this calculation, the need was recognized to use a more conservative iodine removal rate (Reference 12.a.27), a more conservative distance to the LPZ boundary (Reference 12.a.28), a higher control room inleakage rate and a higher normal (Mode 1) CRVS intake air flow rate (Reference 12.a.20).

Revision 2 is issued 10/2011 pending implementation and will be issued final upon receipt of the License Amendment for License Amendment Request 11-06, PG&E Letter DCL-1 1-072. The LAR is associated with resolution of the 230 kV degraded voltage issue described above.

The LOCADOSE computer code (Reference 12.a.6) is used for this evaluation to calculate all control room and offsite doses. The code is installed and executed on PC0000256245, and has been verified and validated in accordance with PG&E's software quality assurance procedures (Reference 12.a.7).

3. Assumptions:

3.1. For all LOCADOSE calculations except those involving RHR pump seal leakage, the values assumed for individual core fission product inventories are calculated for a source term assuming approximately 105 percent full power operation (3580 Mw thermal) immediately preceding shutdown. The core source term is a composite of the source terms calculated for 3.5 percent enrichment and 4.5 percent enrichment (Reference 12.a.8) and is presented in Table 3.1. The composite is generated with the recognition that different isotopes have different maximum activities depending on assumptions regarding enrichment and burnup, with no particular combination of enrichment and burnup being obviously the most conservative. Four bounding source terms from Reference 12.a.8 are compared: 4.5% enrichment at 1000 MWD/tonU, 4.5%

enrichment at 50,000 MWD/tonU, 3.5% enrichment at 1000 MWD/tonU, and 3%

enrichment at 50,000 MWD/tonU. The highest concentration of each isotope is selected from the cases and listed as the Bounding Value in Table 3.1. This composite source term is assumed to exist in all fuel assemblies. This non-mechanistic but conservative approach was first used in Reference 12.a.1.

For the LOCADOSE calculations involving RHR pump seal leakage, the 24-hour post accident iodine fission product inventories are taken from Calculation RRA-4273-004-002 (Reference 12.a.23) and presented in Table 3.2.

3.2. Recirculation loop leakage and RHR pump seal leakage consists of 10% of the core iodine activity consisting of 99.75% elemental and 0.25% organic (Reference 12.a.4, Section 15.5.17.8).

3.3. Consistent with Regulatory Guide 1.4 (Reference 12.a.9), the following are assumed:

3.3.1. Airborne containment activity consists of 100% of the total core noble gas inventory (Section C.1 .b of Reference 12.a.9), and 25% of the total core iodine inventory consisting of 91% elemental, 4% organic and 5% particulates (Section C.I.a of Reference 12.a.9). At the initiation of the LOCA, all activity is assumed to be instantaneously released to the free containment volume and mixed uniformly (Sections C.I.a & b of Ref. 12.a.9).

3.3.2. Consistent with ICRP 2 (Reference 12.a.10) whose use is directed by Section C.2.d of Ref. 12.a.9, the following thyroid dose conversion factors are used for this calculation and are incorporated into the LOCADOSE computer code:

1-131 1.49E+06 (Rem/Ci) 1-132 1.43E+04 (Rem/Ci) 1-133 2.69E+05 (Rem/Ci) 1-134 3.73E+03 (Rem/Ci)

I -135 5.60E+04 (Rem/Ci) 3.3.3. Containment leakage is 0.1%/day (Reference 12.a.1 1) for the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and 0.05% from 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to 30 days (Section C.1 .e of Reference 12.a.9).

DCPP Form 69-20428 (04107110) CF3.1D4 Attachment 6 Design Calculation Page 6of 226 DCA 90000019634 Part 002 Vs 00 (Legacy No. STA-1 95) 3.4. A total control room infiltration rate of 70 cfm is assumed. This includes 10 cfm in leakage consistent with Reference 12.a.9 plus an extra 60 cfm as a contingency to bound any additional unfiltered in leakage to the control room envelope that may be identified during normal plant operation.

3.5. As noted above, this evaluation assumes the immediate release of activity to the containment at the start of the postulated LOCA. For additional conservatism, limiting values are assumed after LOCA initiation for the time delays associated with SI signal generation/actuation and resultant CRVS equipment operation. Additional delays in CRVS inlet damper closure times are assumed in the calculation to bound the maximum potential delays associated with resolution of the 230 kV degraded voltage issue (Reference 12.a.24). All equipment time delays and the event sequence of events are presented in Table 5.1.

3.6 To simulate a 10-second closure time of the CRVS outside air isolation dampers, the dampers are assumed to stay full open for 10 seconds resulting in no filtration of the pressurization flow during this period. This delay is in addition to the SI signal generation/actuation delays (Reference 12.a.4, Table 15.4.1-1 B) per Table 5.1.

3.7 The operation of CRVS and ABVS components as addressed by this evaluation was reviewed relative to resolution of the 230kV degraded voltage issue (Reference 12.a.24).

It was determined that the assumptions in this analysis relative to these systems is limiting. Since early and continued operation of the CRVS fans result in the maximum integrated control room doses, shutdown of this equipment at any time due to loss of offsite power or due to degraded 230 kV conditions would be less conservative (i.e.,

lower integrated dose). Similar for the ABVS, equipment shutdown results in less exposure per gallon of post LOCA recirculation loop leakage (see section 5.4). Thus, normal operation of all ABVS and CRVS equipment as assumed in this analysis is bounding.

3.8 The control room operator breathing rate is assumed to be the public breathing rate for the first 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> (3.47E-04 m3/s) after an accident and is conservatively applied for 30 days (Reference 12.a.9).

3.9 The dose at the EAB is calculated based on two hours following the fission product release per 10 CFR 100.11. The EAB dose calculation is discontinued after two hours by using a X/Q value equal to zero during this period.

3.10 For containment leakage, the control room airflow is conservatively treated as though the pressurization flow starts upon LOCA initiation (at time equal to zero in the LOCADOSE models). This is conservative since more activity is admitted to the control room than if a delay time and fan startup time were to be modeled. The normal CRVS inlet flow to both units is assumed to continue after LOCA initiation at full flow rate for ten seconds until the inlet dampers close. This is conservative since actual damper closure would decrease the flow rate as the flow area decreased.

DCPP Form 69-20428 (04107/10) CF3.1D4 Attachment 6 Design Calculation Page 7 of 226 DCA 90000019634 Part 002 Vs 00 (Legacy No. STA-195) 3.11 The CRVS inlet damper closure delay was not assumed to impact control room dose for auxiliary building leakage (the expected leakage case and the control room dose per one gpm post LOCA recirculation path leakage case (see Sections 5.2 and 5.4 for these.

leakage case descriptions, respectively). This conclusion is reasonable since the dampers will take less than a minute to close, and the earliest that post LOCA recirculation can commence is several minutes after LOCA initiation. Conservatism is already assured by the assumption that recirculation leakage starts at time zero. This assumption was established implicitly in Revision I to this calculation.

3.12 The RHR pump seal failure is assumed to occur at 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after LOCA (Reference 12.a.19). This leakage does not contribute to the two hour EAB dose calculation.

Similarly, the brief CRVS inlet damper closure delays following LOCA initiation do not impact control room dose for this leakage.

3.13 An expected recirculation leak r~te of 1910 cc/hr (approximately 0.008 gpm), as described in Input 4.7, is conservatively assumed to start coincident with the LOCA and to spill to an unfiltered area. This is conservatively treated as a separate dose source independent of detected leakage discussed in Reference 12.b.1.

3.14 The LPZ boundary has traditionally been set to 10,000 meters for dose consequence assessments. This calculation uses 6 miles for conservatism and to be consistent with Safety Evaluation Reports, however, 10,000 meters remains the distance in other analyses and for emergency evacuation planning. See Section 5.7 for further discussion.

4. Inputs:

4.1. The containment free volume is 2.55E+06 ft3 with a sprayed volume of 2.103E+06 ft3 and an unsprayed volume of 4.47E+05 ft3 (Reference 12.a.13).

4.2. Containment spray commences at 106 seconds following LOCA initiation (see Section 5.1 for LOCADOSE modeling discussion). This value includes the limiting delay of 100 seconds following SI signal generation (Reference 12.a.24) and is based on the analyzed scenario in which the high high containment pressure actuation signal occurs prior to the containment spray pumps being sequenced onto the emergency diesel generators. The overall 106 second containment spray delay includes six seconds to account for the limiting LOCA initiation to SI signal generation time delay (Reference 12.a.4, Table 15.4.1-11B).

4.3. The containment spray system has an elemental iodine removal rate of 29/hour and a decontamination factor (DF) cutoff of 100 (crediting spray for iodine removal is directed by Section C.1 .d of Ref. 12.a.9). The spray iodine removal rate had been 31/hour per Reference 12.a. 17, but a more conservative value of 29/hr is used in Revision 2 to this calculation per Reference 12.a.29 as discussed in Reference 12.a.27. The removal rate and DF for organic and particulate iodine are each zero.

4.4. The mixing flow rate from the sprayed to unsprayed containment volumes and vice versa is 94,000 cfm (Reference 12.a.18).

4.16 The normal unfiltered airflow to the control room is 4200 cfm (Reference 12.a.20) 4.17 The distance to the LPZ boundary for this calculation is 6 miles with associated atmospheric dispersion factors as discussed in Section 5.7 (Reference 12.a.28).

5. Methodology:

The recirculation loop margin leakage'rate is defined as the amount of leakage in excess of the expected leakage from recirculation loop components outside containment, whose dose consequences, when combined with the dose consequences from containment leakage and RHR pump seal leakage, will not exceed 10 CFR 100 and 10 CFR 50, General Design Criteria (GDC) 19 dose limits. To determine the margin, the dose components from all post-LOCA leakage sources (i.e., containment leakage, RHR pump seal leakage, expected recirculation loop leakage) and from control room ingress/egress are determined, and subtracted from the

DCPP Form 69-20428 (04/07/10) CF3.1D4 Attachment 6 Design Calculation Page 9 of 226 DCA 90000019634 Part 002 Vs 00 (Legacy No. STA-1 95) dose limit. The margin leakage is the dose margin divided by the dose per one gpm of recirculation loop leakage.

The LOCADOSE code is used to predict post accident doses at the control room, the Exclusion Area Boundary (EAB), and the Low Population Zone (LPZ). The leakage pathways contributing to dose (dose pathways) consist of leakage from the containment, normal leakage from post LOCA recirculation path piping in the Auxiliary Building (termed expected leakage), and leakage from a failed RHR pump seal assumed to occur 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after the LOCA. In addition, operations personnel in the control room are assigned a fixed control room egress/ingress dose.

Additional analyses are performed to develop dose rates per gpm of post LOCA recirculation path leakage in either filtered or unfiltered locations of the Auxiliary Building. The results of these calculations are then used with the available dose margin to determine the margin leakage rates for ABVS filtered and unfiltered post LOCA recirculation path leakage for the control room, EAB and LPZ. The limiting location provides the acceptance criteria for operational post LOCA recirculation leakage that is routinely identified and tracked via STP M-87 (Reference 12.b.1). STP M-87 scales the unfiltered leakage detected (if any) by a multiplication factor to generate an equivalent filtered leakage. The minimum acceptable value of the scaling factor for the various dose mechanisms is generated in Section 7 by ratioing the dose consequences for unfiltered to filtered leakage.

A description of each of the LOCADOSE models used to determine the control room and offsite dose components due to post-LOCA leakage is as follows:

5.1 Containment leaka-qe The containment leakage model for this evaluation is depicted below in Figure 5.1:

Figure 5.1: LOCADOSE Model Schematic Sprayred Re0ion 0. 1%/day Control Room Mqixing flow Atmospheric Dispersion (X/Q)

Unsprayed Region In LOCADOSE, the sprayed containment region is modeled as user-defined Node 2 and the unsprayed region as user-defined Node 3. By default in LOCADOSE models of this type, the environment is always Node 1 and the control room is always the last node (Node 4 in this case). This model is identical to the model used in Calculation STA-087 Revision 1 except as

DCPP Form 69-20428 (04/07/10) CF3.1D4 Attachment 6 Design Calculation Page 10 of 226 DCA 90000019634 Part 002 Vs 00 (Legacy No. STA-195) noted below.

The radioactivity release from containment is modeled as occurring immediately after the initiation of the LOCA. Containment spray is initiated at 106 seconds after LOCA initiation with an iodine removal rate of 29 per hour for elemental iodine. The activity in the upper containment region (sprayed volume of 2.103E+06 ft3) is mixed with the activity in the lower region (unsprayed volume of 4.47E+05 ft3) via a forced recirculation flow of 9.4E+04 cfm from two containment fan cooler units. The unfiltered release rates to the environment are assumed to be at the Technical Specifications maximum allowable leakage rate (L,) of 0.1%/day of the containment volume during the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of the accident and 0.05%/day of the containment volume from 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to 30 days.

The CRVS normal intake is assumed to be isolated upon receipt of the SI actuation signal caused by the LOCA. A total inflow of 6370 cfm (4200 cfm unfiltered normal supply flow, 2100 cfm filtered pressurization supply flow and 70 cfm unfiltered control room boundary in-leakage) is assumed while the normal intake dampers are open for both units. After 18 seconds, the normal intake dampers in the unaffected unit (the unit without the LOCA) are assumed to be fully closed, reducing the unfiltered normal supply flow rate by 2100 cfm. After 44.2 seconds, the affected unit's normal intake dampers are also closed and the CRVS is assumed to be in Mode 4 line up with a pressurization flow of 2,100 cfm, a recirculation flow of 2100 cfm, and a total infiltration flow of 70 cfm. A summary of the preceding scenario is presented in Table 5.1 and an expanded discussion of relevant CRVS operation is presented in Section 5.5.

5.2 Expected recirculation loop leakage Expected recirculation loop leakage of 1910 cc/hr (Input 4.7) is assumed to have existed prior to the LOCA and occurs throughout the 30-day analysis period. All leakage is assumed to have remained in the auxiliary building for a long period such that no partitioning occurs. Additionally, no ABVS filtration of the leakage is assumed to occur. The leakage is modeled in LOCADOSE with a single user-defined volume (Node 2) containing 4.69E+05 gallons of source activity (Input 4.5). The control room is Node 3, and the 1910 cc/hr leak occurs from Node 2 to the environment.

5.3 RHR pump seal leakage RHR pump seal leakage is modeled in LOCADOSE with a single use defined volume (Node 2) containing 3.7322E+05 gallons of source activity (Input 4.6). The control room is Node 3. A leakage rate from Node 2 to the environment of 50 gpm starts at 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after LOCA initiation and lasts for 30 minutes (Input 4.8).

ABVS filtration is assumed for all leakage. To take into account a DF of 132 (Input 4.13) applied to the elemental iodine contained in the leakage, the corresponding ABVS filter efficiency of 90% (Input 4.12) is further increased by a factor of 132 resulting in an adjusted efficiency of:

SRHR = 100 x {1 - [(1 - 0.9)/132]} = 99.924%

5.4 Dose per one qpm of recirculation loop leaka-qe After the dose components from all post-LOCA leakage sources and from control room ingress/egress are determined, and subtracted from the dose limit, the remaining dose margin is converted to an equivalent recirculation loop leakage. Four LOCADOSE calculations are performed to determine the dose per one gpm of recirculation loop leakage for control room

DCPP Form 69-20428 (04/07/10) CF3.1D4 Attachment 6 Design Calculation Page 11 of 226 DCA 90000019634 Part 002 Vs 00 (Legacy No..STA-1 95) pressurization flow with and without ABVS filtration, and for control room infiltration with and without ABVS filtration. These calculations also provide similar dose per gpm values with and without ABVS filtration for the LPZ and EAB. For each dose component, the margin leakage is the dose margin divided by the dose per one gpm of recirculation loop leakage.

5.5 Control Room Ventilation System The CRVS has two input paths, unfiltered outside air via the normal intake path, and filtered outside air through a pressurization path. Figure 5.2 shows a schematic that is typical for Unit 1 and for Unit 2.

In normal or Mode 1 operation, 2100 cfm normal inlet flow enters the control room via Dampers MOD-3 and MOD-3A and Fan E-35 exhausts to atmosphere via MOD-8 and MOD-8A. An equivalent supply flow is provided via the other unit, for a total of 4200 cfm of unfiltered air. Fan S-35 is on, Fan S-98 off and Damper M-4 is closed. While there is recirculation, there is no filtered recirculation.

Upon receipt of an SI signal/Phase A isolation signal, CRVS Mode 4 (Pressurization) is initiated for the selected unit and Mode 3 operation is initiated on the other unit. Figure 5.2 shows a typical alignment in pressurization mode. Dampers MOD-3 and MOD-3A close to stop the normal supply flow of unfiltered air and the normal exhaust path isolates. Pressurization Fan S-98 starts and dampers MOD-1B and MOD-1C open, bringing in 2100 cfm of filtered air. Only one pressurization fan may be operated between the two units at any one time, so the total filtered airflow into the control room is 2100 cfm. Damper M-4 opens resulting in 1050 cfm of recirculation flow through filters per unit (2100 cfm total). The control room envelope is actually pressurized such that any leakage would be outward to atmosphere. Previous revisions of this calculation assumed a constant 10 cfm of unfiltered inleakage into the control room envelope.

This revision assumes an extra 60 cfm (for a total of 70 cfm) as a contingency to bound any additional unfiltered in leakage to the control room envelope that may be identified during normal plant operation.

The conservative sequence of events for this analysis assumes that the pressurization train starts immediately, since even though the flow is filtered, it adds radionuclides to the control room. The 70 cfm of inleakage is also conservatively added as starting immediately. The unaffected unit's normal inlet dampers start to close upon receipt of the SI actuation signal at 8 seconds. No closure is credited for 10 seconds such that full inlet flow is assumed for 18 seconds from the start of the event. The affected unit's normal inlet dampers are assumed to close at 44.2 seconds resulting in zero normal inlet flow at this time. The above sequence of events and associated control room envelope inlet flow summary is presented in Table 5.1.

This analysis, consistent with previous analyses, is performed separately for the unfiltered inlet flow (termed infiltration cases) and the filtered inlet flow (termed pressurization cases). The resulting control room doses are combined to get the total control room dose.

In both the infiltration and pressurization cases, the total outlet flow is set equal to the total inlet flow. Total flow is 6370 cfm for the first 18 seconds based on 4200 cfm unfiltered plus 70 cfm in-leakage plus 2100 cfm pressurization. The total outlet flow between 18 and 44.2 seconds is reduced to 4270 cfm. The total outlet flow after 44.2 seconds is 2170 cfm based on 70 cfm infiltration and 2100 cfm pressurization flow. This approach was verified to produce the same control room dose as that predicted by modeling both infiltration and pressuriiation flows simultaneously. Maintaining the separate files demonstrates that though the unfiltered flow is small in integrated airflow compared to filtered flow over 30 days, the dose from the infiltration case is more than one third of the total control room thyroid dose.

In this calculation, each dose pathway's unfiltered infiltration inlet flow is modeled in a LOCADOSE model scenario labeled "xxx-inf2" where "xxx" is "con" for containment leakage,

DCPP Form 69-20428 (04/07/10) CF3.1D4 Attachment 6 Design Calculation Page 12 of 226 DCA 90000019634 Part 002 Vs 00 (Legacy No. STA-195)

"rhr" for RHR seal failure, "exp" for expected leakage, "unf" for the 1 gpm of unfiltered recirculation loop leakage, and "fil" for the 1 gpm filtered recirculation loop leakage. The number 2 indicates Revision 2 of the calculation.

In this calculation, each dose pathway's filtered pressurization inlet flow is modeled in a LOCADOSE model scenario labeled "xxx-pre2" where "xxx" is "con" for containment leakage, "rhr" for RHR seal failure, "exp" for expected leakage, "unf" for the 1 gpm of unfiltered recirculation loop leakage, and "fil" for the 1 gpm filtered recirculation loop leakage.

Consistent with previous revisions of this calculation and to allow better quantification of the impact of changes on flow path dose contributions, the dose contributions due to infiltration and pressurization are determined in separate models (i.e., the "-inf2" and "pres2" case pairs discussed above). Each case pair could be run as a single case (and would be more physically realistic) using a common CRVS exhaust flow rate that is the total of the infiltration and pressurization flow rates. Since the cases are separated, it is intuitive that the same exhaust flow should be used in each case pair. (Note that mass balance is not maintained but this is not a necessary property in the LOCADOSE calculational framework.) Using the same exhaust flow for the case pairs is numerically correct since LOCADOSE uses the inlet flow to determine the quantity of radionuclides entering the control room, and the outlet flow to model the reduction in radionuclide concentration due to exhaust. Additionally, sensitivity runs verify that the combined dose of the inf2 and pre2 cases exactly equals the resultant dose should both the infiltration and pressurization flows be modeled simultaneously.

5.6 Spray Termination LOCADOSE has the ability to track the time that the sprays have lowered the Iodine concentration to the point where a specified DF is achieved. Calculation N-167 (Reference 12.a.1) established a DF of 100 as a reasonable lower limit to spray efficiency per Reference 12.a.17 and its use is continued in this calculation.

5.7 Atmospheric Dispersion Factors at LPZ Boundary The Atmospheric Dispersion Factors (X/Q values) used for the LPZ in Reference 12.a.1 were apparently selected from Regulatory Guide (RG) 1.4 assuming a distance of 10,000 meters.

However, the original Diablo Canyon Safety Evaluation Report (SER) described X/Q values that appear appropriate for 6 miles. Specifically, X/Q values from the SER are, for 0-8 hours, 8-24 hours, 1-4 days, and 4-30 days: 2.40E-5, 4.8E-6, 1.5E-6, and 3.4E-7 sec/m 3, respectively. The respective X/Q values from Reference 12.a.1 are: 2.20E-5, 4.75E-6, 1.54E-6, and 3.4E-7 sec/m3. Itwas decided, for this calculation, to use the more conservative value (i.e., the larger of each X/Q) for each distance, which generally corresponds to 6 miles.

The sources for these values are charts in Regulatory Guide 1.4. Using the shorter distance of 6 miles (conservatively rounded down to 9600 meters for use in the tables), and bounding all the X/Q values used historically, suggests X/Q values for 0-8 hours, 8-24 hours, 1-4 days, and 4-30 days of: 2.40E-5, 4.8E-6, 1.54E-6, and 3.4E-7 sec/m 3 , respectively. Figures 5.3 and 5.4 show the support for these values. Note that in Figure 5.4, the value of 1.54E-6 sec/m 3 is higher than indicated by the graph and the value in the original SER was lower at 1.5E-6 sec/m 3.

However, 1.54E-6 sec/m 3 is conservative and consistent with Reference 12.a.1.

7. Body of Calculation:

As described in Section 5.5, two calculations are performed for each dose pathway - one for the control room with pressurization flow and no infiltration, and one for the control room with infiltration and no pressurization flow. The offsite doses at EAB and LPZ determined from each calculation are identical since no parameters impacting these doses are changed.

For illustrative purposes and similar for all calculations (as previously discussed above), the LOCADOSE files associated with the control room infiltration case (each named with prefix "xxx-inf2" where "xxx" is "con" for containment leakage, "exp" for expected leakage, "rhr" for RHR seal failure, "unf" for the 1 gpm of unfiltered recirculation loop leakage, and "fil" for the 1 gpm filtered recirculation loop leakage) are presented in the Attachments and are described as follows:

" Radiation transport input model (for the transport of radiation from the release point to the environment - input file xxx-inf2.lti

• Dose consequences model - input file xxx-inf2.ldi

• Isotopic library - input file con-inf2.lib (other cases use identical libraries)

• Dose calculation results - output file xxx-inf2.lto The isotopic library input file is the same for each calculation and is only presented once since only the file name changes from calculation to calculation. Also, the radiation transport output file (i.e., xxx-infi.lto) for each calculation is not included in the appendices. See the attached CD for all files associated with each calculation.

Similar files are created with titles xxx-pre2 for the pressurization cases. These files differ from the xxx-inf2 files only in terms of the air flow rate to the control room. EAB and LPZ doses are identical between the xxx-inf2 and xxx-pre2 files.

Table 7.1 presents a description of each calculation, the file name for each calculation and the appendix that lists the content of each file for that calculation.

Table 7.2 presents the calculated control room and offsite doses using the LOCADOSE models described above and in Section 5, Methodology. By inspection, the thyroid dose is the limiting dose for the control room and offsite locations, so only the thyroid doses need be considered for margin leakage rate determinations. Using the doses in Table 7.2, the margin leakage rates are determined below based on:

Margin leakage (ML) = dose margin / dose per one gpm recirculation loop leakage (filtered or unfiltered)

Control Room For filtered leakage:

MLfiltered = (30 - 20.70) rem / 22.091 rem/gpm = 0.421 gpm For unfiltered leakage:

MLunfiteed = (30 - 20.70) rem / 219.82 rem/gpm = 0.042 gpm

EAB For filtered leakage:

MLfiltered = (300 - 118.223) rem / 98.2 rem/gpm = 1.851 gpm For unfiltered leakage:

MLunfiltered = (300 - 118.223) rem / 977.1 rem/gpm = 0.186 gpm LPZ For filtered leakage:

MLfiltered = (300 - 22.761) rem / 26.61 rem/gpm = 10.40 gpm For unfiltered leakage:

MLunfiltered = (300 - 22.761) rem / 264.80 rem/gpm = 1.047 gpm

8. Results:

The calculated dose rates are shown in Table 7.2. The dose that is the greatest fraction of its respective regulatory limit is the control room personnel thyroid dose of 20.70 rem relative to the GDC 19 criterion of 30 rem.

The margin leakage rates for the control room and offsite locations are summarized below:

Dose Location Filtered/Unfiltered Margin Leakage (gpm)

Control Room Filtered 0.421 Control Room Unfiltered 0.042 EAB Filtered 1.851 EAB Unfiltered 0.186 LPZ Filtered 10.40 LPZ Unfiltered 1.047 Table 7.2 also includes minimum scaling factors for use in Reference 12.b.1 for converting leakage in unfiltered areas into leakage within filtered areas.

9. Margin Assessment:

The calculated dose margins and margin leakage rates are shown in Table 7.2.

The margins established in STA-195, Revision 1, are decreased in Revision 2 due to the additional containment spray delay, slightly more conservative control room flow assumption (the unit dampers closing at 18 and 44.2 seconds), more control room inleakage, and the more conservative iodine removal rate. The limiting dose margin in Revision 1 was 18.45 rem (30 rem - 11.55 rem) for Control Room personnel thyroid dose relative to the limit of 30 rem. In this calculation the margin is reduced to 9.30 rem which is a decrease of 9.15 rem or reduction of 50% from the Revision 1 margin.

The limiting margin leakage rate is decreased from 1.85 gpm filtered to 0.421 gpm filtered, and from 0.186 unfiltered to 0.042 unfiltered. Each constitutes a 77% reduction in leakage rate.

10.

Conclusion:

All criteria regarding maximum post-LOCA doses are met. Table 7.2 presents the calculated dose margins and margin leakage rates.

The limiting margin leakage rate is for the control room with 0.42 gpm filtered and 0.0421 gpm unfiltered.

Including the infiltration due to the assumed delays in closure of the CRVS normal inlet air isolation dampers and the increase leakage rate, and including the delay in spray to 106 seconds after SI signal initiation, the total control room thyroid dose is 20.70 rem. The total dose in Revision 1 of this calculation is 11.55 rem, hence the total increase in dose is 9.15 rem.

However, since all reported doses are below the applicable regulatory criteria, increasing the closure times of the normal inlet dampers and delaying spray to 106 seconds is deemed acceptable.

Notes:

1 - Consistent with STA-1 95 Revision 1 and for ease of modeling, CRVS fans running during Mode 4 operation are assumed to be running at time zero. Since supply fan operation increases control room dose, maximizing fan run time by coincidentally assuming all fans operating at time zero is conservative. Per design for Mode 4 operation, one normal supply fan (S35-38) and one booster fan (S39-41) per unit is running, and one pressurization fan (S96-99) total is running. (See Section 5.5 for a schematic showing these fans and associated dampers) 2 - Six sec delay from LOCA initiation to SI signal generation (Reference 12.a.4, Table 15.4.1-1 B) 3 - Two sec delay from SI signal generation to actuation (Reference 12.a.24, Table 2) 4 - MOD-3, 3A in each unit are normally open and MOD-2, 2A are normally closed. Infiltration is 2100 cfm per unit.

5 - Ten sec delay assumed for inlet damper closure (Ref. STA-1 95 Rev. 2) 6 - 28.2 sec delay from SI signal generation to DGs loading onto 4kv buses (Reference 12.a.24, Table 2) 7 - 100 sec (limiting) delay from SI signal generation until containment spray begins (Reference 12.a.24, Table 2) 8 - The containment spray stops based on iodine concentration assuming DF = 100, therefore this time for spray termination is an output of the model, not an assumed input (see Section 5.6).

1. Proposed Activityllmplementing Document No: Unit Imp Dec Rev No:

STA-195 (9000019634), Design Basis Dose Consequences and Recirculation [0 1 [02 ED J&2 2 Loop Margin Leakage Rates Briefly describe what is being changed and why; SCOPE Calculation STA-195: As the Analysis of Record (AOR), determines and documents the radiological dose following a Loss of Coolant Accident (LOCA). This Includes the offsite dose release to demonstrate compliance to 10 CFR 100, and the control room personnel dose to demonstrate compliance with GDC 19. These results are then used to establish the post-LOCA recirculation loop allowable leakage rates.

CHANGES STA-195 Changes (1) Decrease the containment spray Iodine removal rate from 31 hr 1 to 29 hr".

(2) Redefine the Low Population Zone (LPZ) Boundary (2)(a) Decrease the distance from 10 km to 6 miles. "

(2)(b) To be consistent with the 6 mile LPZ boundary distance change In Item 2a, increase the following LPZ atmospheric dispersion factors (X/Q):

(2)(b)(1) 0-8 hour: from 2.2E-5 to 2.4E-5 s/m3 3

(2)(b)(ii) 8-24 hour. from 4.75E-6 to 4.8E-6 sem (3) Increase the delay time for Containment Spray (CS) delivery time from 86.5 seconds to 106 seconds (which Includes a six second delay from LOCA Initiation to SI signal generation).

The spray delay time of 86.5 seconds assumed in the AOR Is calculated based on time to signal Initiation, diesel generator start time, the sequence load time, end containment spray pipe fill time. [Note: The 86.5 second delay was not added to the FSAR when an earlier LOCA dose AOR (STA-087 Revision 0) was issued in 1998 to specifically address this new delay (previously 81.5 seconds). The 66.5 second delay was reported to the NRC via a routine 10 CFR 50.59 report via PG&E Letter DCL-02-049 dated 4/26/02.] The increase In spray delay time from 86.5 seconds to 106 seconds Is due to potential delays associated with the undervoltage scenario described in SAPN 50301167.

Per PG&E -Design Input Transmittal DIT-50301167-1-0, the 106 second spray delay is comprised of. 1) a limiting delay of six seconds between LOCA Initiation and SI signal generation per FSARU Table 15.4.1-11B, and 2) a limiting delay of 100 seconds between the SI signal generation time and start of containment spray into containment per PG&E DIT-50301167-1-0, Table 1. In order to Incorporate the longer delay times Into the licensing basis, additional analysis Is also being performed (such as containment Integrity analyses) but which Is outside the scope of this LBIE AD. This calculation revision Includes the maximum potential containment spray delay Impact on LOCA radiological dose associated with resolution of the 230 kV degraded voltage Issue described In SAP Notification 50301167.

(4) Increase the Initial Control Room Ventilation System (CRVS) Intake air flow rate for normal (Mode I operation) from 2100 cfm to 4200 cfm.

The sublject AOR assumes that the Initial flow rate is increased from 2100 cfm total to 2100 cfm per unit (per DCM S-23F, Section 4.3.2) or 4200 cfrn total. This Intake flow rate is reduced to 2100 cfm total when the non LOCA unit Inlet dampers are assumed to close.

(5) Increase the delay time of the normal CRVS Inlet damper closure from 10 seconds to 18 seconds on the unit not experiencing the LOCA, and from 10 seconds to 44.2 seconds on the unit experiencing the LOCA.

The current damper closure delay time for both units Is ten seconds from receipt of the SI actuation signal, which is assumed to occur at time zero. In addition to the existing ten second delay and to change the time zero of the analyzed sequence to the time of LOCA Initiation, this activity will add the following additional damper closure delays to both units' dampers: 1) a limiting delay of six seconds between LOCA Initiation and SI signal PG&E Diablo Canyon

Form 69-10430 (07106110) TS3.1D2 Attachment 8.1 LBIE Screen - Applicability Determination Page 2 of 3 generation per FSARU Table 15.4.1-11B, and 2) a limiting delay of two seconds between the SI signal generation time and SI actuation per PG&E DIT-50301 167-1-0, Table 1. Also, the closure of the LOCA unit's intake dampers will be delayed until EDG start and loading due to degraded 230 kV voltage. PerTable 2 of the DIT, the EDGs are assumed to load onto the 4 kV buses at 26.2 seconds after SI actuation. In summary, the non-LOCA-unit Inlet damper closure delay is 18 seconds (6 + 2 + 10) and the LOCA unit Inlet damper closure delay Is 44.2 seconds (6 + 2 + 26.2 +10).

(6) Increase the assumed control room envelope infiltration rate from 10 cfm to 70 cfm.

The infiltratlon rate was increased as a contingency to bound any additional unfiltered In leakage to the control room envelope that may be Identified during normal plant operation.

REASONS FOR CHANGES STA-1 95 is being revised to Include bounding equipment operation delays associated with resolution of the 230 kV degraded voltage Issue and provide more conservative values for selected Input parameters. Furthermore, Item (5) corrects a previous error that Incorrectly used a single unit value of 2100 cfm. The actual Mode I Intake air flow to the control room envelope Is 2100 cfm per unit (per DCM S-23F Section 4.3.2), or 4200 cfm total.

5. Remarks: (Use this section to provide sufficient justification(s) per TS3.JD2, step 5.1.3 for determlnatidns In step 2 and conclusion In step 3.)

2.a: The proposed activity involves a change to the Facility Operating Ucense since the input assumption changes for the increased CS delay time and Increased CRVS Inlet damper closure time yields dose results that exceed the 10 CFR 100 and GDC 19 limits without offsetting input assumption changes for other Input parameters. Chapter 15 of the current FSARU does not specifically allow the LOCA radiological consequences analysis input changes to be rbvised in order to maintain the consequences within the 10 CFR 100 and GDC 19 limits. The proposed activity must therefore be submitted to the NRC for approval to allow the proposed LOCA radiological consequences analysis Input changes to be Incorporated Into the FSARU and to allow the offsetting analysis Input changes to maintain the consequences within the 10 CFR 100 and GDC 19 limits.
