1.0 Purpose The purpose of this calculation is to demonstrate that the pH of the suppression chamber (torus) water remains continuously above 7.0 following a Loss of Coolant Accident (LOCA) for the 30-day duration of the accident. Based on! Section 6.5.2 of the Standard Review Plan, NUREG-0800 (Ref. 7.20), long-term iodine retention may be assumed only when -the equilibrium suppression chamber water pH is above 7.0. The pH transient of the suppression chamber water is evaluated in this calculation to determine whether the uncontrolled suppression chamber water pH remains above 7.0. If not, theleffect on final pH of adding sodium pentaborate to the suppression chamber via the Liquid Poison System (LPS) is subsequently .determined to verify that the suppression chamber water pH can be maintained above 7.0.

2.0 Methodology and Acceptance Criteria 2.1 Methodology The suppression chamber water pH .is calculated using the methodology described in NUREG/CR-5950 and in Grand Gulf Nuclear Station'Engineering Report GGNS-98-0039. Grand Gulf was one of the NRC's Alternate Source Term pilot plants.

This methodology considers the addition of the following acids and bases to the post-LOCA suppression chamber in the pH calculation:

1. Carbon Dioxide - Carbon dioxide is absorbed from the air to form the weak acid carbonic acid. This acid can reduce pH to a limiting value of approximately 5.65 (Ref. 7.13, §2.2.3) and is* bounded in the initial condition selected for the suppression chamber water. pH.

Therefore, carbonic acid is not expliciily computed but is accounted for in the pH calculation.

2. Hydriodic Acid - Hydriodic acid is produced by the release of iodine from the reactor core as fuel failure occurs. Hydriodic acid i's added to the suppression chamber during the Gap Release Phase and during the Early In-Vessel Phase only. This occurs for a two-hour period at the beginning of the LOCA per Regulatory Guide 1.183 (Ref. 7.10.2).

3. Cesium Hydroxide - Cesium hydroxide is produced by the release of cesium from the reactor core as fuel failure occurs. Cesium 1,ydroxide is added to the suppression chamber during the Gap Release Phase and during.the Early In-Vessel Phase only. This occurs for a two-hour period at the beginning of the LOCA per Regulatory Guide 1.183 (Ref. 7.10.2).

4. Nitric Acid - Nitric acid is produced by irradiation of water and air during the LOCA. Nitric acid is added to the suppression chamber continuously during the LOCA.

5. Hydrochloric Acid - Hydrochloric acid is produced by radiolysis of chlorine-bearing electrical insulationfjacketing during a LOCA. Only electrical cable exposed to free air or in cable trays is considered. Hydrogen chloride formed from cable enclosed in conduit or enclosures will be: contained in the conduit or enclosure and will not be available to form acid in the suppression chamber. Hydrochloric acid is added to the suppression chamber continuously during the*LOCA. Hydrochloric acid can also be produced by pyrolysis of chlorine-bearing electrical insulationfjacketing at temrperatures near 5720F -(Ref. 7.13, §2.2.5.3); however, since post-LOCA containment temperatures are much lower than this, pyrolysis is not considered herein.

6. Concrete Core Aerosols - Per NUREG/CR-5950 (Ref. 7.13, §2.3.2), aerosols from limestone concrete will contain the basic oxides CaO, Na2O, and K20. However, the aerosols are produced from the interaction of a molten core with concrete and, per SECY-94-302 (Ref.

7.21), core damage can be assumed to cease after the Early In-Vessel Phase. Therefore, concrete core aerosols are not considered in this calculation.

The acids and bases are combined ini the suppression chamber water and the resulting pH transient response is calculated for a 30-day period. This pH is the unbuffered suppression chamber water pH.

I NEP-DES-08 Rev-07

CALCULATION CONTi Project: Nine Mile PointNuclear Station Ret.

A final pH after 30 days is then recalculated considering the addition of sodium pentaborate from the LPS. This injection is manually initiated, so the pH transient is subject to the timing of the injection. Since only acids are addedto the suppression chamber water after the initial two-hour release of cesium hydroxide, the final pHiis the lowest pH that will be attained in the suppression chamber water.

2.2 Computer Programs The analysis performed herein utilizes! Microsoft Excel (Ref. .7.1), which is commercially available. The validation of Excel is implicit in the detailed review of all spreadsheets used in this analysis. All computer runs were performed using PC. No. 9098 -under the Windows NT operating system.

2.3 Acceptance Criteria The acceptance criterion is that the supp'ression chamber water pH is at or above 7.0 for the 30-day period of the LOCA so that iodine re-levolution is not a source term.

3.0 Assumptions 3.1 Hydrogen ion activity coefficients are ignored when calculating the pH of the suppression chamber water. Because the suppression chamber is initially filled with demineralized water, the ionic strength is low and any deviation from ideality is negligible for purposes of this calculation.

3.2 The reduction in reactor coolant system (RCS)/suppression chamber water mass due to steam addition to the post-LOCA containment is neglected. This is acceptable since the mass of steam in containment is a small fraction of the total mass of water in the suppression chamber.

3.3 The initial pH in the suppression chamber water and in the RCS is assumed to be at the minimum suppression chamber water Value, 5.5 (Design Input 4.1), expected during normal operation. Although the RCS generally; operates at a minimum pH of 5.6, this assumption is conservative because it leads to the lowest calculated pH.

3.4 The suppression chamber water is assumed to be sufficiently mixed so a single pH adequately represents the pool contents.. Per Design Input 4.14, there are at least 0.3 complete exchanges of water in the suppression chamber per hour. This is judged to provide adequate mixing.

3.5 The Cesium-133 reactor core inventory is conservatively not included in this analysis. Cesium-133 would form additional cesium hydrdxide in the suppression chamber water, increasing the pH. Exclusion of this stable isotope of cesium leads to a lower suppression chamber water pH.

Also note that the stable nuclide inventory is not provided in Reference 7.7. However, Reference 7.7 does include products from the activa tion of Cs-133 such as Cs-134, which is included in this calculation (see Attachment 1, Tables 1-2 and 1-4).

3.6 Since Reference 7.7 does not provide the reactor core inventory of stable isotopes, it is assumed that the quantity of lodine-127 is 30% 6f the quantity of Iodine-129. Based on the cumulative fission, yields presented in Reference 7.26 for thermal neutron fission of U235, U23, Pu239 , and Pu241, this value is greater than will actually occur in the reactor core. The ratio of Iodine-127 to lodineý-129 is computed in the table below based on Reference 7.26. Note that U21 does not undergo thermal neutron fission.

1) Recommended values from Reference 7.26 used herein.

Since iodine contributes to the post-LOCA suppression chamber water acidity, this assumption is conservative as it bounds the actual amount of Iodine-127 which may be in the reactor core.

3.7 It is conservatively assumed that 5% of the iodine released into containment produces hydriodic acid. Per Regulatory Guide 1.183 (Refj 7.10.2), 95% of the iodine released from the RCS is in the form of cesium iodide (Csl), 4.85%0 is in the form of elemental iodine, and 0.15% is in the form of organic iodide. NUREG-1465; (Ref. 7.14) indicates that at least 95% of the iodine entering containment from the RCS is in the form of cesium iodide with no more than 5% as I plus HI. Therefore, for this calculation, it is conservatively assumed that the combined I plus HI NEP-DES-08 Rev 07 M

quantity is the maximum 5% in order to maximize the acid contribution from iodine to the suppression chamber water.

3.8 Radiation dose calculations for gamma and beta total integrated dose (TID) in the drywell used as input are assumed to apply at electrical cable surfaces. Ifattenuation of air was not taken into account in the TID calculations (Ref. 7.6.2/7.6.3), this assumption is conservative in that it uses a higher radiation flux and computes a higher hydrochloric acid production rate. If attenuation of air was taken into account in the TID calcdulations (Ref.,7.6.2/7.6.3), this assumption is moot.

3.9 Assumptions made in the determination of the exposed cable inventory are listed in Attachment 3 and repeated (with minor changes) below for convenience.

All combustible Cable insulation is actually cable jacketing; therefore, the entire mass of cable is exposed to both gamma and betai radiation since no credit'is taken for shielding of the insulation from beta radiation.

All cable is free-air routed and not in cable trays; thus, no credit can be taken for shielding of some of the cables from beta radiation in cable trays (this assumption' conflicts with the combustible loading calculation, Reference 7.6.7, which assumes all cable is in trays; however, since Reference 7.6.7 assumes the cable location, the assumption of free-air routing is acceptable).

There is no cable in the suppression chamber (torus); this is acceptable since little, if any, cable is expected in the suppression chamber.

, Medium and high voltage cables are !not considered-when determining the typical cable size; this is acceptable since small cables maximize 'HCI production and the medium to high voltage power cables are larger thanithe cables identified in Reference 7.23. In addition, the quantity of medium and high voltage power cables inside primary containment is small as the only 5 kV (medium/large) cables in containment feed the reactor recirculation pumps (Ref.

7.29).

The chlorine content of the rubberj hose and plastic covers is unknown; therefore, it is assumed that these materials are PVC.

Filler material in the cables is included in the combustible load provided in Reference 7.6.7.

Therefore, the filler material is accounted for as chlorine bearing material in this calculation.

Oil. in primary containment is confined and therefore any chlorine which could evolve from the oil to form HCl need not be accounted for in this calculation.

3.10 The amount of sodium pentaborate !added to the suppression chamber as a buffer is conservatively assumed to be the minimum mass contained by the LPS injection tank 3.11 The minimum suppression chamber water temperature is modeled as 600 F. This temperature is used to determine the maximum suppression chamber water mass, given the volume. Given that cOntainment is located within the environmentally controlled reactor building, this value is judged to be acceptable for a minimum temperature.

3.12 The gamma radiation dose used herein lis increased by 5% to account for bremsstrahlung. This conservative increase is justified as follows:

I The fraction of beta energy that is converted to bremsstrahlung (or gamma radiation) is estimated using the equation (Ref. 7.24,!p. 110):

NEP-DES-08 Rev 07

Ref.

Fraction= k *Z *E where:,

Fraction = the fraction of beta energy converted to bremsstrahlung k = 0.7x103 per MeV Z = atomic number of the absorber E = energy of the beta particle [MeV]

For this calculation, absorption in air,. water, or PVC is considered, so a conservative value for Z would be 20. Similar to gamma energy, the beta energy is different for each radionuclide.

Assuming the average beta energy per decay is the same as the average gamma energy per decay, :and using a typical gamma energy of 1 MeV, the fraction converted to bremsstrahlung would be' Fractioh = 0.7x103

20 "1 = 1.4%

Inspection of the beta energies for noble gases, iodines, and cesiums in Reference 7.25 indicates that, for most radionuclides, the gamma energy per decay is higher than the beta energy per decay. Using a fraction of 5% is large enough to account for the. cases where the beta energy per decay is larger than! the gamma energy per decay, and to account for bremsstrahlung from pure beta emitting radionuclides.. Therefore, the assumption that the bremsstrahlung contribution to the dose is equal to 5% of the gamma dose is considered conservative.

4.0 Design Input 4.1- The initial suppression chamber water pH is maintained between 5.5 and 8.0 (Ref. 7.3.1). The suppression chamber water pH is no longer monitored at NMP1 per Reference 7.3.3; therefore, this value is taken from a prior (c. 2001) revision of the NMP1 Chemistry Manual.

4.2 For Reactor Conditions 3 (reactor thermall power > 25%) and 2 (reactor water bulk temperature >

212 0 F), the Action Level 1 acceptable RCS pH range is 5.6 < pH < 8.6. The Action Level 2 pH range is 4.9 < pH< 9.3 and the Action Level 3 pH range is 4.6 < pH < 9.6 (Ref. 7.3.2, p. 9).

4.7 The suppression chamber water temperature range is 60°F s T < 850F for continuous plant operation (Assumption 3.11 and Ref. 7.2.2). However, the maximum temperature can rise to 1100F before reactor shutdown is required (Ref. 7.2.2).

4.8 The initial suppression chamber / drywell, pressure is 14.7 psia, consistent with the original DBR containment suppression chamber heatup analysis as documented in UFSAR Table XV-32a (Ref.' 7.11.1).

4.9 The reactor core cesium and iodine inventories are determined in Attachment 1, and are repeated below for convenience since th'ey are input to the pH analysis. These quantities are conservatively based on the activities at time t=0 following a LOCA.

lodines: 43.2 gram-moles Cesiums: 268.6 gram-moles.

The above core inventories are based. on a core thermal power of 1,887 MWt (102% of licensed core thermal power, 1,850 MWt), consistent with Regulatory Guide 1.49 (Ref. 7.10.1).

It should be noted that the quantity of cesium given above excludes Cesium-133, which is stable, since it is not provided in Reference 7.7.1 The exclusion of the stable isotope is conservative as it would form cesium hydroxide (CsOH).which would raise the pH of the post-LOCAsuppression chamber water. The stable cesium would form cesium hydroxide since the number of moles of non-stable cesium is greater than. 95% of the number of moles of iodine (95% of cesium is released as cesium iodide, Csl - see Assumption 3.7).

4.10 The gamma (y)dose in the drywell, wetwell, and suppression chamber water is determined in Attachment 2 and is repeated below for convenience since it is input to the pH analysis. The submersion dose is calculated for both the minimum and maximum suppression chamber water volume Since it is dependent on the dilution volume.

The liquid poison tank contains a minimum of 1,325 gallons of boron bearing solution per Technical Specification 3.1.2 (Ref. 7.2.1). ' Sodium pentaborate solution with a minimum concentration of 9.423 weight % is used for the liquid poison (Ref. 7.6.4.a, p. 6). The specific gravity (SG) of this solution is 1.048 per Figure 1 of Reference 7.22. However, Reference 7.22 is for Unit 2 which uses boron with less B1 10 enrichment than Unit 1 (;-25 atom % for Unit 2 vs.

!62.5 atom % for Unit 1). Therefore, *Unit 1 will actually have a lower specific gravity. To account for this, a specific gravity of 1.0 is conservatively used for the LPS solution.

The above weight percentage (9.423 Mt %) is only valid for sodium pentaborate enrichments greater than or equal to 62.5 atom percent B-10 (Ref. 7.6.4.a, p. 6).

Sodium pentaborate decahydrate has the chemical formula Na 2 B* 0 *16 *10HpO (Ref. 7.22, §3.3.1) and a molecular weight of 585.984. 'This molecular weight is determined using a boron molecular weight of 10.387 [(0.625*10.013)+(0.375*1 1.009)] to account for the 62.5 atom percent B-10 enrichment (see Ref. 7.9 for isotopic masses of B-10 and B-11). In this calculation, "sodium pentaborate" actually refers to, sodium pentaborate decahydrate for consistency with plant documentation.

The sodium pentaborate solution shall be maintained between 70°F and 1050 F per the operating procedure (Ref. 7.3.4, p. 3). The low and high temperature annunciators are set at 650 F and 850 F, respectively (Ref. 7.4, §2.7). Note that the minimum temperatures bound the Technical Specification minimum allowable solution temperature of 40°F (Ref. 7.2.1, Figure 3.1;2b).

Each sodium pentaborate pump (NP02A and NP02B) has a 33 gpm rated capacity at 1,300 to 1,670 psig (Ref. 7.4,ý §2.1). However, the nominal capacity is 30 gpm per the Technical Specification (Ref. 7.2.1) and operating p~rocedure (Ref. 7.3.4, p. 3).

4.13 The chloride bearing cable inventory in! primary containment is determined to be 1,400 Ibm of free-air routed PVC jacketed cable with an outer diameter of 0.22 inches and a jacket thickness of 0.030 inches in Attachment 3. This mass also includes the mass of any cable insulation -and filler material.

4.14 The limiting Design Basis Accident (DBA) LOCA is identified in UFSAR Section VI-B.1.2 (Ref.

7.11.2) as an instantaneous double ended rupture (DER) of the RCS recirculation line (largest line in- containment). For this case, a diesel generator failure is the limiting single failure as it NEP-DES-08

results in only one core spray pump and one core spray topping pump being available per UFSAR Table XV-11 (Ref. 7.11.4). Given .1 that the reactor vessel depressurizes reasonably quickly! for a large break LOCA, the minimum flow rate from one core spray pump and one topping pump is expected to be between.2,000'to 3,000 gpm per UFSAR Table XV-9a .(Ref.

7.11.3)-. In addition, at least one containment spray pump will. be operable with a minimum flow rate of 3,600 gpm per UFSAR Table XV-32a (Ref. 7.1.1.1; also see p. VII-14a of .UFSAR). Thus, a minimum flow rate of. 5,600 gpm is expected when core .spray is actuated. This flow rate equates to approximately 0.5 complete exchanges of the water in the torus per hour (1 complete exchange in approximately

5.0 Calculations 5.1 Suppression Chamber Water Initial Conditions 5.1.1 'Suppression Chamber Water Volume The maximum and. minimum suppression chamber water volume, are used in this calculation. The total suppression chamber water volume for this calculation is the sum of the initial suppression chambter water volume plus the added RCS .volume. The complete RCS mass is added to the suppression chamber-at the start of the LOCA for the maximum volume case. The RCS mass is not added to the suppression chamber for the

.minimum volume case.

The suppression chamber water volume at the maximum water level is .86,000 ft3 . The

-.Reactor Coolant System (RCS) has a total mass of. 501,500 Ibm. Once the RCS mass is added to the suppression charmber, the total suppression: chamber water volume is approximately 94,000 ftW (Attachment 4, Table 4-9). The mixed water volume is based *on the initial density of the suppression chamber3 water.. The suppression chamber water volume at the minimum water level is 79,800 ft .

5.1.2 Initial pH The suppression chamber water lis maintained at a pH between 5.5 and 8.0. Lower pH levels are conservative for this analysis, so an initial pH of 5.5 is used. This pH also accounts for dissolved carbon dioxide.

The RCS pH is maintained at a pH between 5.6 and 8.6 for Reactor Conditions 2 and 3, and between 5.3 and 8.6 for AReactor Condition 1 (reactor water bulk temperature <

212 0F). Since the large break LbCA in which the entire RCS inventory is spilled to the suppression chamber is postulated to occur at full power, the pH at Reactor Condition 1 is not used. A conservative initial RCS pH of 5.5 (bounds 5.6) is used for this analysis. The choice of this conservative input does .not impact the final result of this calculation due to the small (<10%) RCS water mass relative to the suppression chamber water mass.

The pH of the suppression chamber contents after addition of the RCS is 5.5.

r W wdri Mrit- At-rir I M11 Hydriodic acid is formed by the post-LOCA release of elemental iodine (I)'and hydrogen iodide (HI) from the reactor core and its absorption in the suppression chamber water.

Per Regulatory Guide 1.183, Table 1 (Ref. 7.10.2), 5% of the iodine core inventory is released into containment during the Gap Release Phase and an additional 25% of the iodine core inventory is released into containment during the Early In-Vessel (EIV) Phase. The Gap Release Phase has an onset of 2 minutes and a duration of 30 minutes and is followed by the EIV Phase with a duration of 90 minutes per Table 4 of Regulatory Guide 1.183 (Ref. 7.10.2).

-Re.

The reactor core inventory of iodine, the Gap Release Phase iodine release, and the EIV Phase iodine release are determined in Attachment 1 and listed in Attachment 1, Table 1-1.

Per Section 3.5 of Regulatory Guide 1.183 (Ref. 7.10.2), 95% of the iodine released from the RCS is in the form of cesium iodide, 4.85% is in the form of elemental iodine, and 0.15% is in the form of organic iodide. Section 3.5 of NUREG-1465 (Ref. 7.14) and Section 4.2 of NUREG/CR-5732 (Ref. 7.16) indicate that at least 95% of the iodine entering containment from the RCS is in the form of cesium iodide with no more than 5% as I plus HI. For this calculation, it will be conservatively assumed~that* the combined I plus HI is the maximum 5% in order to maximize the acid contribution from iodine to the suppression chamber water.

The formation of hydriodic acid in the suppression chamber water is equal to the molar addition of iodine. Computations are shown in Attatchments 4 and 6, Tables 4-2 and 6-2. During the Gap Release Phase, 5% of the Gap Release Phase iodine release produces hydriodic acid in the suppression chamber water. During the EIV Phase, 5% of the EIV Phase iodine release produces additional hydriodic acid in th~e suppression chamber water. The concentrations are determined at the end of the Gap Release Phase, at one hour, and at the end of the EIV Phase.

The rates of addition during the Gap Release Phase and during the EIV Phase are linear- per Section 3.3 of Regulatory Guide 1.183*(Ref. 7.10.2). No additional hydriodic.acid is formed after the EIV Phase.

5.3 Cesium Hydroxide (CsOH)

Cesium hydroxide is formed by the release of cesium from the reactor core and its absorption in the suppression chamber water.

Per Regulatory Guide 1.183, Table 1 (R!ef. 7.10.2), 5% of the cesium core inventory is released into containment during the Gap Release Phase and an additional 20% of the cesium core inventory is released into containment during the Early In-Vessel. (EIV) Phase. The Gap Release Phase has an onset of 2 minutes and a duration of 30 minutes and is followed by the EIV phase with a~duration of 90 minutes per Table 4 of Regulatory Guide 1.183 (Ref. 7.10.2).

The reactor core inventory of cesium, the Gap Phase cesium release, and the EIV Phase cesium release are determined in Attachment 1 and listed in Attachment 1, Table 1-2.

Cesium released in the form of cesium iodide does not contribute to formation of cesium hydroxide. The quantity of cesium iodide is 95% of the molar quantity of iodine released, consistent with the determination of hydriodic acid production (see Section 5.2). The amount of cesium as cesium iodide is subtracted from the Gap Phase cesium release and the EIV Phase

.cesium. release to obtain the quantity' of cesium hydroxide in the post-LOCA suppression chamber water.

The formation of cesium hydroxide in the suppression chamber water is equal to the molar addition of cesium not-in the form of cesium iodide. Computations are shown in Attachments 4 and 6, Tables 4-5 and 6-5. The concentrations are determined at the end of the Gap Release Phase, at one hour, and at the end of, the EIV Phase. The rates of addition during the Gap Release Phase and during the EIV Phase are linear per Section 3.3 of Regulatory Guide 1.183 (Ref. 7.10.2). No additional cesium hydroxide is formed after the EIV Phase.

5.4 Nitric Acid (HNO 3)

Nitric acid is formed by irradiation of air and water in the suppression 'chamber by gamma radiation. Per Section 2.2'4 of NUREG/CR-5950 (Ref. 7.13), the generation rate of HNO3 , G, is 0.007 molecules HNO 3 per 100 eV. This generation rate converts to 7.3x10- g-mole/liter per MegaRad as follows:

Computations are shown in Attachments 4 and 6, Tables 4-3 and 6-3. ,

5.5 Hydrochloric Acid (HCI)

Hydrochloric acid is formed by radiolysis of chloride-bearing electrical cable in the drywell.

The chlorine bearing cable inventory is: determined in Attachment 3. The cable inventory is based on the NMP Unit 1 combustible loading calculation, SO.0-FPE-002 (Ref. 7.6.7).

The methodology for computing hydrochloric acid production in GGNS-98-0039, Revision 1 (Ref.

7.12.1) differs from that used in GGNS-98-0039, Revision 3 (Ref. 7.12.2). The hydrochloric acid production rate in GGNS-98-0039, Revision 1, is based on the mass of cable jacket and on the.

radiation dose rate at the cable jacket surace multiplied by a flux averaging factor. However, the hydrochloric acid production rate in GGNS-98-0039, Revision 3, is based on the cable jacket surface area and on the energy release per unit volume of containment, diminished by attenuation in air between the center of containment and the cable surface. Both methodologies use thesame G value (with units converted to rads in GGNS-98-0039, Revision 1) and the same expression for energy absorption fraction in the cable jacket. Consistent with Assumption 3.8, which, is conservative, the GGNS-98-0039,. Revision 1, methodology for hydrochloric acid production is used herein.. The benchmark (§5.8) demonstrates that both methodologies yield very similar results, and therefore the choice of the GGNS-98-0039, Revision 1, methodology used in this calculation is considered acc'eptable.

Hydrochloric acid generation in chlorine-bearing material in the cable is determined using the following equation from Appendix B of NUREG/CR-5950 (Ref. 7.13) and further developments from Grand Gulf Engineering Report GGNS-98-0039, Revision 1, Appendix A (Ref. 7.12.1):

Hydrochloric acid formed by beta radiatibn is computed at varying times using the TID for beta radiation in .the drywell multiplied by the 'generation rate. Since all cable is modeled as free-air routed, no localized shielding from beta, radiation for cables in cable tray is included.

The mass of hydrochloric acid. generated by gamma and beta radiation is divided by the post-LOCA suppression chamber water volume to determine the total concentration of HCl formed by irradiation of electrical cable as a function of time.

The computations determining the hydrdchloric acid generation are presented in Attachments 4 and 6, 'Tables 4-4 and 6-4.

5.7 Sodium Pentaborate Addition Sodium pentaborate can be added via the Liquid Poison System (LPS) to buffer the suppression chamber water, resulting in higher pH values.

The LPS contains an aqueous solution of sodium pentaborate (Na2B10O16.10H 20). The solution is prepared by mixing borax (Na2 B4*O*1OH 2O) and boric acid (H3BO 3 ) in a 1:6 stoichiometric molar ratio in distilled water (Ref. 7.22, §4.4). This yields sodium pentaborate (Na2B,00 16 or Na20,5B203) and water.

Sodium pentaborate dissociates in water lin accordance with the following equilibrium:

Na2 B1 0 0 16 o10H 2 0+6H2 0 <--O!2Na+ +2B(OH)- +8B(OH) 3 This buffers the pH in accordance with:

[anion]

pH = pK, + log [acid]

H= pKa + log [B(OH);] i

[B(OH),]

where:.

K,= equilibrium constant for the sodium pentaborate dissociation The sodium pentaborate dissociation constant is temperature dependent in accordance with the following correlation (Ref. 7.12.2, §6.1):

K, =(0.0585 T + 1.309) *1 10 1 temperature in OF This correlation is based on temperature data from 5-10°C (41-1220F). However, Reference 7.12.2 states the following regarding the correlation: "...linear extrapolation of this data to temperatures above 50 0C is expected to result in conservatively high dissociation constants and correspondingly lower pool pH values.ý' Therefore, use of this correlation with suppression chamber water temperatures greater than 122 0F is conservative.

Due to the nature of the correlation for tjie pentaborate dissociation constant, a bounding 30-day suppression chamber water temperature of 200°F is used. Use of a higher temperature results in a lower final pH.

The minimum volume of the LPS injection. tank is 1,325 gallons and the concentration of the sodium pentaborate solution is 9.423% at that volume based on the decahydrate (includes water of hydration) as defined in Technical Specification 3.1.2 (Ref. 7.2.1) and Reference 7.6.4.a. The specific gravity of this solution is 1.048 (Ref. 7.22, Figure 1). The minimum mass of sodium pentaborate can be calculated:

Both methodologies use the same G value (with units converted to rads in GGNS-98-0039, Revision 1) and the same expression for energy absorption fraction in the cable jacket. The benchmark also demonstrates that both methodologies yield very similar results.

The final suppression -pool pHji calculated by the spreadsheets herein is 4.07 in Comparison to 4.03 in the. GGNS calculation. This is considered sufficiently accurate to benchmark the model developed for this calculation.

Similarly, the model determining the final suppression pool pH following SLCS addition. is ibenchmarked. Both the model herein and the GGNS calculation predict a final pH of 8.46.

All cable in primary containment is modeled as PVC although it is probable that a great deal of this cable is a chlorosulfonated polyethylene (CSPE) such as Hypalon. The hydrochloric acid production rate for PVC is 3.7 times greater than for Hypalon.

All cable in primary containment is m deled as being free air routed. Thus, self shielding of

cable from beta radiation is ignored. I.This has a significant impact as beta radiation is the main source of HCl production due to its high (-1) absorption factor into the cable.

The core inventory of cesium-133 is ilot included in this analysis. This stable isotope would increase the pH in the post-LOCA slppression chamber water since'it would form cesium hydroxide.

6.4 Conclusions Therefore, based on the results presented in Sections 6.1 and 6.2,- the LPS is required at NMP Unit 1 to control the post-LOCA suppression chamber water pH. The LPS will not be required until approximately 9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months post LOCA, even postulating the worst case scenario, i.e. with the conservatisms listed in Section 6.3.

Nine Mile Point Nuclear Station Revision 0 Unit I Page 1-1 Attachment 1 Determination of Reactor Core Inventories Calculation No. H21C08/ 4V Nine Mile Point Nuclear Station Revision 0 Unit 1 Page 1-2 Purpose The purpose of this attachment is to document the inventory of all iodine and cesium isotopes in the reactor coire.

Methodology:

The reactor core inventory is calculated using GE document GE-NE-A41-00097-00-01, DRF A41-00097-00, "Nine Mile Point Unit 2 24-Month Cycle Fission Product Inventory Evaluation,"

(Ref. 7.7 in main body). Case 3, which addresses a single batch core with 1,400 Effective Full Power Days (EFPD) and 34,000 MWd/ST Expected Core Average Exposure (CAVEX), is conservatively used to determine the inventories. The inventory at both t=0 and t=30 days (720 hours0.00833 days 0.2 hours 0.00119 weeks 2.7396e-4 months ) is calculated to demonstrate that the values at t=0 are conservative.

The use. of the Unit 2 fission product inventory isjconsidered bounding for Unit 1 for the following reasons. First, the inventory of short lived nuclides is nearly proportional to power level, so that for these nuclides normalized activities (Ci/MWt)! generated at a power level of 3,467 MWt would be essentially identical to normalized activitieýs generated at a power level of 1,850 MWt.

Second, the in'ventory of long lived nuclides is more dependent on burnup. The average burnup at the end of cycle for Unit 1 is approximately 30,000 MWd/ST [(44,000 MWd/ST)*(2/3)] based on an equilibrium reload batch discharge exposure of 44,000 MWd/ST and the replacement of approximately 1/3 of the core during each refueling (UFSAR Section IV-A.1.0, main body Reference 7.11.8). Therefore, the use of the 34,000 MWd/ST Unit 2 activities is bounding for long lived nuclides.

GE-NE-A41-00097-00-01 presents the activity in! Ci/MWt. To convert this to core inventory, the methodology on p. 29 of the Radiological Healthl Handbook (Ref. 7.8 in the main body) is used.

3.7x10 10 disintegrations per second per Curie Once the total core inventory~I is known, the fractions released during the gap release phase and early in-vessel (EIV) phase are determined in accordance with the guidance provided in Table 1 of Regulatory Guide 1.183 (Ref. 7.10.2 in main body). This table is summarized below for alkali metals such as cesium and halogens such as iodine.

1. Stable cesium is conservatively not included in the cesium inventory.

2. The mass of iodine-127 is assumed to be 30% of the mass of iodine-129.

Results The results below are taken from Tables 1-1 through 1-4.

Nine Mile Point Nuclear Station I Revision 0 Unit 1 Page 2-1 Attachment 2 Determination of; Radiation Doses SI- _

Calculation No. H21C08$

Nine Mile Point Nuclear Station Revision 0 Unit 1 Page 2-2 Purpose The purpose of this attachment is to document the gamma and beta radiation dose in the drywell, wetwell, and suppression chamber water.

Methodology Beta Dose-The beta radiation dose is taken from Calculation S3.1 1-DWLOCA-BETA, Revision 0 (main body Reference 7.6.2). I The beta dose in S3.1 1-DWLOCA-BETA is presented for three scenarios:

1. No halogen plate-out (p. 41) 2.- For plate-out of elemental iodines (p. 48), arid

3. For instantaneous plate-out (p. 50).

Since the values for the scenario with no hal1ogen plate-out are greater than the other two scenarios and hence more conservative, they are used herein. The values reduced by 50% to account for self shielding are used herein.

The beta dose for Unit 2 is smaller than for Unitil because Unit 2 assumes all halogen activity is plated out while Unit 1 assumes it is airborne. Fior the Unit 2 beta dose calculation, 100% of the noble gases are airborne, *iodines are reduced by suppression pool scrubbing, and 100% of remaining iodines are plated out (Calculation PR-C-19-C, p. 5). For Unit 1, 50% of the iodines are assumed to remain airborne along with 100% of the noble gases in the. beta dose calculation (Calculation S3. 11 -DWLOCA-BETA, p. 3).

Since the penetrating ability of beta radiation i§ orders of magnitude less than that of gamma radiation, the beta dose from the suppression chamber water is considered negligible -in comparison to the suppression chamber submersion gamma dose. Therefore, the suppression chamber submersion beta dose is not modeled.'

Drywell and Wetwell Airborne Gamma Dose The gamma radiation dose is formulated using the total integrated dose (TID) from. NEDO-.

24290 (main body Reference 7.27) and the Unit 2 gamma radiation dose profile from Calculation PR-C-21-Q, Revision 1 (main body Reference 7.6.3). The Unit 1 gamma radiation dose is obtained by normalizing the Unit 2 prof ile to the Unit 1 6 month TID (provided in Table 4-3 of NEDO-24290) as follows:

TIDul_airbme = TlDu2_.rto6 * (TIDui 6mo / TlDu2_6rAo)

The drywell and wetwell airborne accident. gamma TID is taken from Zone 1 in Table 4-3 of

NEDO-24290. The Zone 1 TID is for the drywvell with no vessel shield and bounds all other zones analyzed in NEDO-24290, including the wetwell, and therefore is'conservative.

i Calculation No. H21C08OI Nine Mile Point Nuclear Station Revision 0 Unit 1 Page 2-3 Suppression Chamber Water Submersion Gamrna Dose' The Unit 1 suppression chamber water submersion gamma dose is scaled from the Unit 2 suppression pool submersion gamma dose provided in PR-C-21-Q. The Unit 2 submersion gamma dose is taken from environmental zones PC 175101, PC 196112, and PC 215121, which represent the suppression pool, in PR-C-21-Q.

The Unit 1 submersion gamma dose is scaled by the core thermal power (P) and dilution volumes (V). This scaling is consistent with ýPR-C-21-Q, where the TID is determined as follows:

TID = DCF* (AN)

The DCF is a dose conversion factor [rad/(Ci/6c)], A is the amount of activity released to the suppression pool [Ci], and V is the dilution volumne (volume of the suppression chamber water)

[cc]. From this expression it is clear that the TID can be scaled.

TID, / TID 2 = [DCF *(AN,)] / [DCF*(A 2N 2)]

or, since the DCF is a constant, TID 2 = TID 1 * (A2/Al) * (V1N 2) -

Since activity is directly proportional to core thermal power level (see Attachment 1), P, the above expression is also equivalent to:

TlDuj sub = TIDu 2_sub * (Pu1/Pu) * (VuNu1)

General Comments on Gamma Dose Determinations It should be noted that all Unit 2 radiation dose profiles used herein are for the originally analyzed core thermal power level of 3,323 MWt, not the uprated core thermal power level of 3,467 MWt. This has no impact on the results Of this analysis.

Both the drywell/wetwell airborne gamma dose and the suppression pool submersion gamma dose are increased by 5% to account for bremsstrahlung.

Results The radiation'doses to be used are shown in T"bles 2-1 and 2-2.

Nine Mile Point Nuclear Station Revision 0 Unit 1 Page 3-1 Attachment 3 Determination of Primary Containment Exposed Cable Inventory I.

jft/o/o.S : Calculation No: H21C08/-t Nine Mile Point Nuclear Station I Revision 0 Unit 1 Page 3-2 Purpose The purpose, of this attachment is to determine the primary containment exposed cable inventory.

It is expected that NMP Unit 1 will require use of the Liquid Poison System (LPS) based on previous experience, regardless of how the cable inventory is determined. Therefore, use of the conservative methodology presented herein is considered acceptable.

Mass of Cable Insulation/Jacketing in Primary Containment Since cable insulation and jacketing is combustible, it is included in the combustible load for fire area/zone FA3/R1, "RB 225' to:el. 332' Primary Containment Torus Area" (Ref. 1, p. B5). The total combustible load for FA3/R1 is given ;in the following table. Quantities from the combustible loading calculation (Ref. 1) andi Table 3.1.1 of Appendix 10A (Fire Hazards Analysis) to the UFSAR are presented since they are different. For the purposes of the post-LOCA suppression chamber water pH calculatidn, the calculation (Ref. 1) values are used.

Combustible Material Quantity (Ref6 1) Quantity (Ref. 3 - UFSAR)

Cable insulation. 744 744 Rubber '_ 36 n/a

-Oil 1,104 1,310 Wire insulation 25 2541 Plastic 180 n/a Motor insulation . 363 250 Of the combustible loads listed above, the cable insulation, wire insulation, motor insulation, rubber, and plastic could be chlorine-bearing material. The total weight of these materials is 1,364 .Ibm [744+36+41+180+363], of which .1,148 Ibm [744+41+363] is .insulation. This inventory excludes cable routed in conduit anrd junction boxes (Ref. 1, p. 5, Assumption 1),

which is consistent with the methodology used to determine HCI production for pH analyses.

The rubber hoses and plastic covers on lead blankets (Ref. 1, p. A25) are included since they may contain chlorine and therefore may contribute to HCI production. The mass of the rubber and plastic are modeled the same as cable jacketing. Oil may include chlorine-bearing compounds such as chlorinated solvents, but is enclosed and would contain any HCI that might be formed.

Note that the total chlorine bearing material weight for Unit 1 (1,364 Ibm) is greater than that for Unit 2 (-620 Ibm per Ref. 2, p. 4-7). For conservatism, 1,400 Ibm is used for the post-LOCA suppression chamber water pH calculation.

Chemical Composition of Cable Insulation/Jacketing There are three types of cables used at Nine Mile Point Unit 1: power cable, control cable, and instrumentation cable. All of these cable types can contain a chlorine -bearing insulation or jacket material. Per Section IX-B.3.4 of the UFSAR (Ref. 3), some of the possible chlorine bearing insulation and jacket materials are neoprene, polyvinyl chloride (PVC), chlorosulfonated polyethylene (CSPE), and Hypalon (a CSPE).; It is noted that this differs slightly from the 600V cable specifications (Refs. 6-8) which state that the cable jacketing is all black CSPE. The chemical properties of these materials are provided below:

57% Ref. 5 52.2.5.1 Ref. 4, Kerite CSPE n/a n/a 18% Ref. 2, p. 3-28 Weight % chlorine varies from 24-43% per NUREG/CR-5950 for commercial product with filler.

Thus, based on the above information, it is Conservative to model all cable insulation and jacketing in containment as PVC. Note that this differs from NMP Unit 2 in which the majority of cable in containment is Kerite CSPE, conservativlely modeled as Hypalon.

The rubber hose and plastic covers are also modeled as PVC since more detailed information regarding their chlorine content is not available.

Properties of PVC Insulation/Jacketing The properties of cable insulationfjacketing required for the post-LOCA 'suppression chamber water pH analysis are as follows: density, linear absorption coefficient, and radiation G value.

These properties are provided below for PVC. 1 Per Reference 10 (p. 6-200), the specific gravity of flexible PVC ranges from 1.16 to 1.7; thus, the density ranges from 1.16 to 1.7 g/cm . N6te that the-density of Hypalon, 1.55 g/cm 3, is similar (Ref. 1.1, p. 13).

Since carbon, is a major constituent of PVC, (C 2H3Cl)n, the following values relating the linear absorption coefficient (a) to material density (p) !from Reference 11 (p. 13) can be used:

ap = 0.06371cm 2/g an/p = 33.6 c m2/g For the purposes of this calculation, a smaller linear absorption coefficient is conservative since it leads to greater radiation penetration and lhence a greater quantity of insulation/jacketing.

affected by radiation. Therefore, when determining the linear absorption coefficient, the lower

'bound PVC density (1.16 g/cm 3) is used. !This leads to the following linear absorption coefficients for PVC:

= 0.0739 cm" [(0.0637 cm 2/g)*(1.16 g/cm 3)]i ao = 38.976 cm' [(33.6 cm 2ig)*(1.16 g/cm 3)]

The G Value for PVC is 7.7 molecules HCI per i,100*eV in a vacuum at room temperature, which is greater than the 2.1 molecules HCI per 100' eV G value for Hypalon in a vacuum at room' temperature (Ref. 4, §2.2.5.2). The G value ýin a vacuum at room temperature is meant to represent a balance between the increased HCI production at elevated temperatures expected during accidents and the neutralization potential of fillers in the cables. Although the neutralization potential of fillers in PVC jacl~etedhnsulated cable is less than in Hypalon jacketed/insulated cable per. NUREG/CR-5950J the G value in a vacuum at room' temperatures is still considered acceptable for the following reasons:

Calculation No. H21C08ft4 Nine Mile Point Nuclear Station Revision 0 Unit 1 Page 3-4

The NMP Unit 1 primary containment vessels (drywell and pressure suppression chamber) are purged with nitrogen to maintain less than 4% oxygen per UFSAR.Section VI-E.1.1 (Ref.

3). Therefore, the G value in a vacuum is reaistic for NMP Unit 1

Since all 600V cable jacketing is actually CSPE per the cable specifications (Refs. 6-8), it is probable that much of the insulation combustible load is CSPE or Hypalono. Therefore, the application of the PVC G value to the entire insulation mass is conservative.

Thus, the G value to be used herein* for PVC is 7.7 molecules HCl per 100 eV. Note that this represents an HCI production 3.7 [7.7/2.1] times greater for the radiolysis of PVC than for the radiolysis of Hypalon. This is the primary difference between the use of PVC versus, Hypalone.

It should also be noted that the use of the G value in a vacuum at room temperature is consistent with the G value suggested for use with Hypalon in NUREG/CR-5950 (Ref. 7.13).

Grand Gulf, an NRC pilot plant for AST implementation, also adopted the G value in a vacuum at room temperature for Hypalon in Engineering Report GGNS-98-0039 (Ref. 12, Appendix A).

Selection of Typical Cable Size The typical cable size is selected based on the NMP Unit 1 cable specifications (Refs. 6-8).

Typical cable 'sizes are presented in the following table.

A typical cable size is selected which maximizes predicted HCI production. Based on the flux averaging factor and absorption fraction (Ref. 2, §5.5), the minimum cable outer diameter and minimum jacket thickness yield conservative results. For smaller cables with thin jacketing, the amount of radiation applied to the jacket is nearly equal to the incident radiation on the surface; hence HCI production is greatest with said cables.

Therefore, a cable with an outer diameter of 0.22 inches and a jacket thickness of 0.030 inches is used for the pH analysis.

Modeling Assumptions The following assumptions are used in the determination of the. primary containment cable inventory. The cumulative effect of these assumptions is extremely conservative.

" Assume all combustible cable insulation is actually cable jacketing; therefore, the entire mass of cable is exposed to both gammaI and beta radiation since no credit is taken for

.shielding of the insulation from beta radiation

Assume all cable is free-air routed and not in cable trays; thus, no credit can be taken for shielding of some of the cables from beta radiation in cable trays (this assumption conflicts with the combustible loading calculation, Reference 1, which assumes all cable is in trays; however, since Reference 1 assumes the cable-location, the assumption of free-air routing is acceptable)

No cable, is assumed in the suppression chamber (torus); this is acceptable since little, if any, cable is expected in the suppression chlamber

OVA* Calculation No. H21C08pt Nine Mile Point Nuclear Station Revision 0 Unit 1. Page 3-6 Final Medium and high voltage cables are not considered when determining the typical cable size; this is acceptable since small cables maximize HCI production and the medium to high voltage power cables are larger than the cables identified in References 6-8. In addition, the quantity of medium and high voltage power cables inside primary containment is small as the only 5 kV (medium/large) cables in containment feed the reactor recirculation pumps (Ref. 9).

The chlorine content of the rubber hose. a'nd plastic covers is unknown; therefore, it is assumed that these materials are PVC.

It is assumed that any filler material in the cables is included in the combustible load provided in Reference 1. Therefore, the filler material would be accounted for as chlorine bearing material in this calculation.

It is assumed that the oil in primary containment is confined and therefore any chlorine which could evolve from the oil to form HCI rneed not be accounted for in this calculation.

Summary of'Cable Inventory in Primary Containment For the post-LOCA suppression chamber water pH analysis, the primary containment cable inventory is as follows:*.

1,400 Ibm of free-air routed PVC jacketed cable with an outer diameter of 0.22 inches and a jacket thickness of 0.030 inches References

1) Pool Volume is computed as follows: (msp / psp)*28.31685 lft

2) The HI, HCI, and CsOH concentrations calculated inTables 4-2, 4-4, and 4-5 are based on the SP volume from Table 4-9.

To adjust for the SP volume as it changes throughout the LOCA, the concentration from Tables 4-2, 4-4, and 4-5 is multiplied by the following factor. VaSIN 5 p where Vbws* is the volume in Table 4-9 and VSP is calculated in this sheet:.

3) The HNO 3 concentration does not directly utilize the SP volume and therefore is not adjusted as described in Note 2. However, the HNO 3 generation is based on pH2o=1000 g/l. To account for the density in the post-LOCA SP, the concentration from Table 4-3 is multiplied by ps-P / 1000 g/l

1) Pool Volume is computed as follows: (msp / psp)*28.31685 Vft3 -

2) The HI, HCl, and CsOH concentrations calculated in Tables 4-2, 4-4, and 4-5 are based on the SP volume from Table 4-9.

To adjust for the SP volume as it changes throughout the LOCA, the concentration from Tables 4-2, 4-4; and 4-5 Is multiplied by the following factor: VbNsp where Vbasi is the volume in Table 4-9 and VSP is calculated in this sheet.

3) The HNO 3 concentration does not directly utilize the SP volume and therefore is not adjusted as described in Note 2. However, the HNO 3 generation is based on pH2= 1000 g/l. To account for the density in thepost-LOCA SP, the concentration from Table 4-3 3

is multiplied by psP / 1000 gA
