1.0 Purpose The purpose of this calculation is to demonstrate that the pH of the suppression pool 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 pool pH. is above 7.0. The pH transient of the suppression pool is evaluated in this calculation to determine whether the uncontrolled suppression pool pH remains above 7.0. If not, the effect on final pH of adding sodium pentaborate to the suppression pool via the Standby Liquid Control System (SLCS) is subsequently determined to verify that the suppression pool pH can be maintained above 7.0.

2.0 Methodology and Acceptance Criteria 2.1 Methodology The suppression pool 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 pool 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 pool pH. Therefore, carbonic acid is not explicitly computed -but is accounted for in the pH calculation.

2. Hydriodic Acid - Hydrioclic acid is produced by the release of iodine from the reactor core as fuel failure occurs. Hydriodic acid is added to the suppression pool 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 hydroxide is added to the suppression pool 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 pool continuously during the LOCA.

5. Hydrochloric Acid - Hydrochloric acid is produced by radiolysis of chlorine-bearing electrical insulation/jacketing 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 pool. Hydrochloric acid is added to the suppression pool continuously during the LOCA. Hydrochloric acid can also be produced by pyrolysis of chlorine-bearing electrical insulation/jacketing at temperatures near 5720 F (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, Na20, 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 in the suppression pool and the resulting pH transient response is calculated for a 30-day period. This pH is the unbuffered suppression pool pH.

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

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 suppression pool pH is at or above 7.0 for the 30-day period of the LOCA so that iodine re-evolution is not a source term.

3.0 Assumptions I 3.1 The maximum post-LOCA suppression pool volume is used in this calculation. This is conservative for the following reasons:

The concentration of nitric acid is based on the suppression pool submersion gamma TID values from Reference 7.6.3, which are based on a dilution volume which is smaller than the maximum suppression pool Volume used herein (see Attachment 2). Therefore, -the concentration of nitric acid, which is the main contributor to the acidity of the post-LOCA suppression pool (see Attachment 4, Table 4-1), is conservatively over-estimated when the maximum suppression pool volume is used. This conservatively minimizes the post-LOCA suppression pool pH. The over-estimation is a direct result of not reducing the submersion gamma TID to account for the suppression pool volume that is larger than the dilution volume upon which the TID is based.

A larger suppression pool volume would result in lower Concentrations of hydriodic acid and hydrochloric acid, as well as cesium hydroxide. However, since the contribution of cesium hydroxide to ;the post-LOCA suppression pool is orders of magnitude larger than the contributions of both hydriodic and hydrochloric acid (see concentrations in Table 4-1 of Attachment 4), a more dilute solution in which the cesium hydroxide concentration is lowest is conservative for minimizing the post-LOCA suppression pool pH.

Thus, use of the maximum post-LOCA suppression pool volume will result in the minimum post-LOCA suppression pool pH.

3.2 The reduction in. RCS/suppression pool mass due to steam addition to the post-LOCA containment is conservatively neglected. As discussed in Assumption 3.1, use of the maximum suppression pool mass is conservative.

3.3 The initial pH in the suppression pool and in the Reactor Coolant System is assumed to be at the minimum value, 5.3, 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 pool is assumed to be sufficiently mixed so a single pH adequately represents the pool contents. Per Design Input 4.14, there are a minimum of 0.3 complete exchanges of water in the suppression pool 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 hydroxide in the suppression pool, increasing the pH.

Exclusion of this stable isotope of cesium leads to a lower suppression pool pH. Also note that the stable nuclide inventory for NMP U2 is not provided in Reference 7.7. However, Reference 7.7 does include products from the activation 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 Iodine-127 is 30% of the quantity of Iodine-129. Based on the cumulative fission yields presented in Reference 7.26 for thermal neutron fission of U23, U2M, PuM, and Pu 241, this value is, greater than will actually occur in the reactor core. The ratio of Iodine-127 to Iodine-129 is computed in the table below based on Reference 7.26. Note that U23 does not undergo thermal neutron fission. -

1) Recommended. values from Reference 7.26 used herein.

Since iodine contributes to the post-LOCA suppression pool 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 (Ref. 7.10.2), 95% of the iodine released from the RCS is in the form of cesium iodide (Csl), 4.85% 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 quantity is the maximum 5% in order to maximize the acid contribution from iodine to the Suppression Pool.

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. If attenuation 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 calculations (Ref. 7.6.2/7.6.3), this assumption is moot.

3.9 The available G value for hydrochloric acid generation in electrical cable jacketing was developed based on material (Hypalon) with a variable chlorine content. The chlorine content of this material can be higher than the 16+2% chlorine content of the electrical cable jacket material, Chlorosulfonated Polyethylene (CSPE), specified at NMP Unit 2 (see description in NUREG/CR-5950, Ref. 7.13). Use of the available G value is conservative because the application of G involves only the mass of the cable and not the chlorine content; therefore, use of a G value for a higher chlorine content material leads to a higher hydrochloric acid production rate.

3.10 The amount of sodium pentaborate added to the suppression pool as a buffer is conservatively assumed to be the minimum mass contained by the SLCS injection tank.

3.11 Hydrogen ion activity coefficients are ignored when calculating the pH of the suppression pool.

Because the suppression pool is initially filled with demineralized water, the ionic strength is low and any deviation from ideality is negligible for purposes of this calculation.

3.12 The contribution ofthe ethylene propylene rubber (EPR) cable insulation to the hydrochloric acid production is corsidered negligible. This assumption is acceptable, particularly when considering Assumption 3.9, since the EPR cable insulation contains less than 1% chlorine by weight (Ref. 7.19).,

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

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

Fraction = k

Z

E where:

Fraction = the fraction of beta energy converted to bremsstrahlung k = 0.7x10o3 per MeV Z = atomic number of the absorber E = energy of the beta particle [MeV]

For this calculation, absorption in air, water, or CSPE 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:

Fraction = 0.7x10 3 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 frbm 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 pool pH is maintained between 5.3 and 8.6 (Ref. 7.3.1,p. 3).

4.2 The RCS pH is maintained between the following limits (Ref. 7.4, p. B3.4-8):

Mode PH Range 1 (>10% power) . 5.6:<pH5<8.6 2,3 5.6 5 pH S 8.6 All others 5.3 5 pH 5 8.6 For Mode 1 operation, the pH range above coincides with the Action Level 1 acceptable pH range (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. 11).

4.3 The volume of water (liquid and steam) in the Reactor Coolant System (RCS) during normal operation is 24,266 ft3, with a liquid fraction of 0.579. This corresponds to a total liquid mass of 644,850 Ibm and a total steam mass of 24,324 Ibm (669,174 Ibm total water mass). See p. 86 of Reference 7.6.5.

4.4 Linear absorption 'coefficients are determined from input in NUREG-1081 (Ref. 7.15) as follows.

4.8 The suppression 6hamber / drywell pressure is maintained between 14.2 psia and 15.45 psia (Ref. 7.2.2).

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

Iodines: 81.0 gram-moles Cesiums: 503.3 gram-moles The above core inventories are based on a core thermal power of 3,536 MWt (102% of licensed core thermal power, 3,467 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. The exclusion of the stable isotope is conservative as it would form cesium hydroxide (CsOH) which would raise the pH of the post-LOCA suppression pool. The stable, cesium would form cesium hydroxide since 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 pool is determined in Attachment 2 and is repeated below for convenience since it is input to the pH analysis.

The lower boundary is defined by the following endpoints:

4,558.6 gallons of 13.6 weight % sodium- pentaborate solution (SG=1.068).

4,288.0 gallons of 14.4 weight % sodium pentaborate solution (SG=1.071)

The specific gravity (SG) provided above is taken from Figure 1 of Reference 7.22.

It should be noted that the above weight percentages define the lower boundary of acceptable SLCS operation and are only valid for sodium pentaborate enrichments greater than or equal to 25 atom percent B-10.

Sodium pentaborate decahydrate has the chemical formula Na2B10O16-10H 20 (Ref. 7.22, §3.3.1) and a molecular weight of 590.224. In this calculation, "sodium pentaborate" actually refers to sodium pentaborate decahydrate for consistency with plant documentation.

The sodium pentaborate solution is maintained between 750 F and 85 0 F by internally located electric heaters (5ef. 7.3.4, §5.0(B), p. 4). Note that 750 F bounds the Technical Specification lower limit of 70°F (Ref. 7.2.1).

Each sodium pentaborate pump (2SLS-P1A and 2SLS-P1B) must be able to deliver > 41.2 gpm at a discharge pressure ? 1,235 psig (Ref. 7.2.1).

4.13 The chloride beating cable inventory is determined in Table 4-4 of Attachment 4. Information from DIT-NM-NPEE-001 (Ref. 7.19) is used to determine the chloride bearing cable inventory.

4.14 The limiting Design Basis Accident (DBA) LOCA is identified in UFSAR Section 6.2.1.1.5 (Ref.

7.11.1) as Case C of UFSAR Section 6.2.1.1.3 (Ref. 7.11.2), which corresponds to Case C of Reference 7.6.5., For this case, a minimum of one Low Pressure Core Injection (LPCI) pump is operable throughout the accident (Ref. 7.6.5, p. 21).

Cooper H21C-097. 0 5.0 Calculations 5.1 Suppression Pool Initial Conditions 5.1.1 Suppression Pool Volume The maximum suppression pool volume will be used in this calculation. This will result in the calculation of the lowest transient pH and is conservative (see Assumption 3.1). The total pool volume for this calculation is the sum of the maximum initial suppression pool volume plus the added RCS volume. The complete RCS mass is added to the suppression pool at the start of the LOCA.

The suppression pool liquid volume at the maximum water level is 154,400 ft3. The Reactor Coolant System (RCS) has a total volume of 24,266 ft3 , with a liquid fraction of 0.579. Once the RCS mass is added to the suppression pool, the total suppression pool volume is approximately 168,000 ft3 (Attachment 4, Table 4-9).

5.1.2 InitialpH The suppression pool is maintained at a pH between 5.3 and 8.6. Lower pH levels are conservative for this analysis, so an initial pH of 5.3 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 Modes 1, 2, and 3 and between 5.3 and 8.6 for all other Modes. A conservative initial pH of 5.3 is used for this analysis. The'choice of this conservative input does not impact the final result of this calculation.

The pH of the pool contents after addition of the RCS is 5.3.

5.2 Hydriodic Acid (HI)

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 pool.

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).

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) indicates that at least 95% of the iodine entering containment from the RCS is in the form of cesium iodide with normore 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 pool.

The formation of hydriodic acid in the suppression pool is equal to the molar addition of iodine.

Computations are shown in Attachment 4, Table 4-2. During the Gap Release Phase, 5% of the Gap Release Phase iodine release produces hydriodic acid in the suppression pool. During the EIV Phase, 5% of the EIV -Phase iodine release produces additional hydriodic acid in the suppression pool. 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 pool.

Per Regulatory Gtiide. 1.183, Table 1 (Ref. 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 5.3). 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 pool.

The formation of :cesium hydroxide in the suppression pool is equal to the molar addition of cesium not in theform of cesium iodide. Computations are shown in Attachment 4, Table 4-5.

The concentrationrs 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 pool by gamma radiation.

Per Section 2.2.4 of NUREG/CR-5950 (Ref. 7.13), the generation rate of HNO 3, G, is 0.007 molecules HNO 3 per 100 eV. This generation rate converts to 7.3x10.6 g-mole/liter per MegaRad as follows:

Computations are shown in Attachment 4, Table 4-3.

5.5 Hydrochloric Acid (HCI)

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

The types and amounts of cable are as shown in DIT-NM-NPEE-001 (Attachment 3). Two sizes of cable are present in the drywell, 750 MCM power cable and 1/0 ground cable. Jacketing material for both types is chlorosulfonated polyethylene (CSPE). This material contains 16+2%

chlorine. Note, however, that the hydrochloric acid generation rate is determined using the properties of Hypalon (see Assumption 3.9).

The 750 MCM cable has ethylene propylene rubber (EPR) insulation, while the ground cable has no insulation. The insulation material does not contain chlorine (specified as <1%) and consequently does not contribute to HCI formation (see Assumption 3.12).

The mass of jacket material for each cable is computed based on the maximum guaranteed cable outer diameter (OD) and on the jacket thickness per NMP specification NMP2-E023A (Ref.

7.23) as shown on pages 22, 24, and 25 of attached DIT-NM-NPEE-001 (Attachment 3). A density of 1.55 g/cm 3 was used for Hypalon per Section 4.2 of NUREG-1081 (Ref. 7.15). Cable lengths are as identified in DIT-NM-NPEE-001 (Attachment 3). As-built cable lengths are located in cable tray and additional cable lengths are conservatively assumed to be in free air.

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 iniGGNS-98-0039, Revision 1, is based on the mass of cable jacket and on the radiation dose rate at the cable jacket surface 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 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. 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 acceptable.

Hydrochloric acid generation in bchlorine-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):

p = 0.099 cm' for gamma radiation p = 52.08 cm 1 for beta radiation Per NUREG/CR-5950 (Ref. 7.13) the G value for Hypalon is 2.115 molecules HCI per 100 eV.

The chlorine content of this material can be higher than the 16+2% chlorine content of the electrical cable jacket material, Chlorosulfonated Polyethylene (CSPE), specified at NMP Unit 2 ý(see description in NUREG/CR-5950). Use -of the available G value is conservative because the. application of G involves only the mass of the cable jacketing and not NEP-DES-08 Rev 07

the chlorine content. Therefore, use of the G value for Hypalon will overpredict the hydrochloric acid production rate when applied to materials with lower chlorine contents, such as the CSPE utilized in the cables at NMP Unit 2 (Assumption 3.9).

Hydrochloric acid formed by gamma. radiation is computed at varying times using the Total Integrated Dose (TID) for gamma radiation in the drywell multiplied by the generation rate. The total mass of cable, jacketing is determined and then used in the computation.

Hydrochloric acid formed by beta radiation is computed at varying times using the TID for beta radiation in the drywell multiplied by the generation rate. The mass of cable in cable tray is discounted by 50% to account for localized shielding from beta radiation in the tray.

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

The computations determining the hydrochloric acid generation are presented in Attachment 4, Table 4-4ý 5.6 Transient pH Calculation The transient pH was computed by combining the contributions of acids and bases. The concentrations of. [H*] and (OH] were summed and the net resultant concentrations from self-neutralization determined by the relationship:

where:

K, = dissociation constant for water x = [H*] and [OH] self-neutralized 7-[H'] = sum of acids added [g-mole/liter]

Z[OH] = 1sum of bases added [g-mole/liter]

Solving for x:

X= [OH-] + [H4 ] - VqOH-] + [H]-)2 - 4 x (JOH-][HW] - K.)

2 The dissociation constant is temperature dependent, and the temperature function is per the CRC Handbook (Ref. 7.17, consistent with correlation used in Ref. 7.12):

- log(K,) = 15.5129 - 2.24 x 10-2 T + 3.352 x 10--T 2 where:

T = temperature, *F Finally, the suppression pool pH is determined:

[H]= [H4 ]um x pH = - Iog([H*)

5.7 Sodium Pentaborate Addition Sodium pentaborate can be added via the Standby Liquid Control System (SLCS) to buffer the suppression pool, resulting in higher pH values.

The SLCS contains an aqueous solution of sodium pentaborate (Na 2Bl10O16 10H20). The solution is prepared by mixing borax (Na 2B40 7 .0H 20) and boric acid (H3B0 3) in a 1:6 stoichiometric molar ratio in distilled water (Ref. 7.22, §4.4). This yields sodium pentaborate (Na2 B1 oO16 or Na20*5B20 3) and water.

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

Na 2 B1 0 0, 16 . 10H 2 0 + 6H 2 0 <->2Na+ + 2B(OH)- + 8B(OH) 3 This buffers the pH in accordance with:

[anion]

pH = pK8 + log

[acid]

pH = pK, + log [B(OH)4]

[B(OH)3 ]

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) 10.1 temperature in 'F This correlation is, based on temperature data from 5-10TC (41-122°F). However, Reference 7.12.2 states the following regarding the correlation: "...linear extrapolation of this data to temperatures above 50 0 C is expected to result in conservatively high dissociation constants and correspondingly lower pool pH values." Therefore, use of this correlation with suppression pool temperatures greater than 122 0 F is conservative.

Due to the nature of.the correlation for the pentaborate dissociation constant, a bounding 30-day suppression pool temperature of 200°F is used. Use of a higher temperature than will actually exist results in a lower final pH.

The minimum volume of the SLCS injection tank is 4288.0 gallons and the concentration of the sodium pentaborate solution is 14.4% at that volume based on the decahydrate (includes water of hydration) as defined in Figure 3.1.7-1 of Technical Specification 3.1.7 (Ref. 7.2.1). Using the maximum controlled temperature of 85 0F, the minimum specific gravity is 1.068 (Ref. 7.22, Figure 1). The min.imum mass of sodium pentaborate can be calculated:

Mass = volume density

concentration Note that the mass of sodium pentaborate in 4,288 gallons of 14.4% solution is slightly less than the mass in 4,558.6 gallons of 13.6% solution.

The number of moles of sodium pentaborate added to the suppression pool is determined using a molecular weight of 590.224 since the concentration is based on the decahydrate. The amounts of anion and acid are 2 and 8 times this amount, respectively, by stoichiometry.

The equivalents of acid in the unbuffered suppression pool neutralize the equivalents of conjugate base and shift the equilibrium, so, by mass balance, pH = pK,6 + log 2 x mole SP - mole H÷ 8 x mole SP + mole H*

where:

mole SP = moles of sodium pentaborate added to the suppression pool mole HW - moles of acid in unbuffered suppression pool 5.8 Benchmark 5.8.1 Input for pH Calculation Benchmark The pH transient developed in this calculation is determined using a Microsoft Excel (Ref.

7.1) spreadsheet. In order to benchmark the spreadsheets, the design input from Grand Gulf Nuclear Station (GGNS) Calculation No. XC-Q1111-98013, Revision 1, "Suppression Pool pH Analysis," (Ref. 7.12.3) is input into the spreadsheets developed herein. Since Grand Gulf was an NRC pilot plant for Alternate Source Term implementation, the calculation has been accepted by the NRC and is part of the public record.

Case 1 of this GGNS calculation is used to benchmark the model herein. This case assumes that all source terms (except noble gases)-are deposited upon release into the suppression pool water. This maximizes the suppression pool dose and the generation of nitric acid.

Slight differences between the benchmark and GGNS curves beyond 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months are attributed to differences in methodologies between GGNS-98-0039, Revision 1 (Ref.

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 surface 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 NEP-DES-08 Rev 07

6.0 Results 6.1 The pH in the unbuffered post-LOCA suppression pool initially rises due to the influence of cesium hydroxide addition at the beginning of the LOCA, but falls to below a pH 7.0 between approximately 12 to 14 days (see Figure 4-1, repeated below for convenience). The final pH at 30 days without buffering is 4.4, so the suppression pool pH does not satisfy the Acceptance Criterion of a pH greater than 7.0.

6.2 Addition of sodium pentaborate via the Standby Liquid Control System (SLCS) buffers the suppression pool and results in a final pH at 30 days of 8.3. The suppression pool pH will satisfy the Acceptance Criterion of a pH greater than 7.0 with use of the SLC system. The SLCS should be used prior to the suppression pool pH falling below 7.0. When determining the appropriate time to inject the sodium pentaborate, the duration of injection should be considered as well as the amount of time to achieve a homogenous mixture in the suppression pool.

NEP-DES-08 RevO07 Calculation No. H21C-097 Nine Mile- Point Nuclear Station Revision 0 Unit 2 Page 1-1 Attachment I Determination of Reactor Core Inventories

Attachment. 1 Calculation No. H21 C-097 Nine Mile Point Nuclear Station "Revision 0 Unit 2 - Page 1-2 Purpose The purpose of this attachment is to document the inventory of all iodine and cesium isotopes in the reactor core.

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.

Reference 7.7 presents the activity in Ci/MWt. To convert this to core inventory, the methodology on p. 29 of the Radiological Health Handbook (Ref. 7.8 in the main body) is used.

XN ln(2)._N tl/2.M~tl/2 In(2).Na =3.7x1010 XN [Ci1 In(2)-Na g'm = 37x1010.Mt/

where:

XN specific activity [dis/sec/gm]

N number of atoms per gram [atoms/gm]

tI r2 half life [sec]

Na Avogadro constant [atoms/mole]

M molecular weight [gm/mole] = [amu]

3.7x1 010 disintegrations per second per Curie Once the total core inventory 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 I 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.

Group Core Inventory Fraction Released into Containment Gap Release Phase I Early In-Vessel Phase Total Halogens 0.05 I 0.25 0.30 Alkali Metals 0.05 0.20 0.25 Notes/Assumptions See the text in the main bodyfor the basis for these items.

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.

Therefore, use of the values at time=0 is both reasonable and conservative.

Attachment 2 Calculation No. H21C-097 Nine Mile Point Nuclear Station Revision 0 Unit 2 Page 2-2 Purpose The purpose of this attachment is to document the gamma and -beta radiation dose in the drywell, wetwell, and suppression pool.

Methodology Beta Dose The beta radiation dose is taken from Calculation PR-C-19-C, Revision 3 (main body Reference 7.6.2). In order to account for power uprate from 3,323 MWt to 3,467 MWt, the beta dose presented in the calculation is increased by 1.36%.

The beta dose in PR-C-1 9-C is presented for both a drywell surface area of 275,000 ft2 and 200,000 ft2. Since the values for a drywell surface area of 200,000 ft2 are greater and hence more conservative, they are used herein.

Both halogen plate-out and airborne dose are included in the total drywell and wetwell beta dose.

Since the penetrating ability of beta radiation is orders of magnitude less than that of gamma radiation, the beta dose from the suppression pool is considered negligible in comparison to the suppression pool gamma dose. Therefore, the suppression pool beta dose is not modeled.

Gamma Dose The gamma radiation dose is taken from Calculation PR-C-21-Q, Revision 1 (mrain body Reference 7.6.3). In order to account for power uprate from 3,323 MWt to 3,467 MWt,. the gamma dose presented in the calculation is increased by 1.36%.

The drywell and wetwell airborne gamma dose is taken from environmental zone PC 289684.

The long-term gamma dose in this zone bounds that in all other environmental zones analyzed

........ .. -in

. PR-C-21 -Q jand therefore-is conservative.'-........ .............. ... .. .. . .

The suppression pool submersion gamma dose is taken from environmental zones PC 175101, PC 196112, and PC 215121, which represent the suppression pool.

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

It is recognized that the suppression pool submersion gamma dose is based on a dilution volume of 160,000 ft3 (PR-C-21-M, main body Reference 7.6.6). Since this volume is different than that used in this calculation, the impact of a different suppression pool volume is addressed. The total integrated dose (TID) is determined as follows:

TID = DCF * (ANV)

Where DCF is a dose conversion factor [rad/(Ci/cc)], A is the amount of activity released to the suppression pool [Ci], and V is the volume of the suppression pool [cc]. From this expression it Calculation No. H21C-097 Nine Mile Point Nuclear Station Revision 0 Unit 2 Page 2-3 is clear that, since the DCF and A do not change for this analysis, a change in suppression pool volume results in:

TID 1 / TID 2 = [DCF *(ANIV)] I[DCF*(AIV 2 )]

or TID 2 = TID1 * (VlN1 2)

Since, for this analysis, the maximum post-LOCA suppression pool volume, approximately 168,000 ft3 , is used (see main body Assumption 3.1), it is conservative to use the suppression pool submersion gamma dose from PR-C-21-Q without adjustment for suppression pool volume.

Results The radiation doses to be used are shown in Tables 2-1 and 2-2.

SUBJECT:

Determination of exposed cables In the NMP2 Drywell.

PURPOSE:

Cables installed Inthe NMP2 Drywall containing chlorine-bearing materials may release HCI via rediolyals when exposed to various forms of radiation. This DIT estimates the lengths and sizes of cables Installed In the Drywall, that am Installed In cable tray or free air. It also provides Information on cable insulation and jacket material. The user of this DIT can use this information to calculate the exposed surface area of cable jacket material, and the volume of cable jacket and cable insulation material contained by these exposed cables.

ASSUMPTIONS.

1. The calculation results of 'HCI released via rediolysls' may be used in a safety related applicatiori: therefore this DIT will be prepared as Safety Related.

2. The user will calculate cable jacket surface area. and cable jacket and insulation volume from data provided herein.

3, Over-estimates of cable length and size are In a conservative direction for the user of this DIT's data.

4. The Drywall is a plant area Whiere virtually all scheduled cables am Installed in conduit Exceptions are the power cables to the RCPs and their associated free air drops from tray to motor junction boxes. Other scheduled cables are Installed in conduit.

Other potential exceptions may exist for non-scheduled short lengths of lighting or receptacle power cables, or aluminum sheathed cables, etc.

EVALUATION:

1. The user of this DIT is Interested In exposed cable only. Exposed cable Is routed Inopen cable tray or free air. Cable muted in enclosed raceway. Ie. conduit, flexible conduit, pull boxes, etc.. and cable contained Inside equipment. I.e. termination boxes, motors, etc., will not be considered. A review of the Installation specification E061A Indicates that free air cable muting Is typically only allowed as cables enter and exit the cable trays. Therefore, this DIT estimates the cable lengths and sizes of those that are muted Incable tray. There may be some aluminum sheathed or metal clad cable routed in some areas, and the potentlal exists of small quantities of lighting or receptacle cable. These cable types can be muted without the use of a raceway utilizing simple supports and have an overall jacket. Therefore, for conservatism, it will be estimated that the amount of cable Insulation and jacket matarial for cables of this construction is equal to the amount contained in the cable trays.

2. A detailed search of NMP2 cable tray, penetration wirng dis rams, conduit plan and arrangement drawings was performed to 6OP04030203-REV4.doc Rev. Date: 04-19-2004 Calculation No. H21C-097 Nine Mile Point Nuclear Unit Station

.Revision ,. 0 Page 3-4 DESIGN INFORMATION TRANSMITTAL -CONTINUATION PAGE .3 Form SOP-0403-02-03. Revision 4 L'- Z.i Identify any cable tray that is installed in the primary containment Cable tray drawings EE-034AA and EE-034Z for Reactor Building El. 215'. and drawings EE-034AG and EE-034AF for Reactor Building El. 289' indicate that ther are no trays installed In the Drywell or Suppression Pool for these elevations. Cable tray locations were verified utilizing the tray support drawings EE-340H and EE.340G.

3. Cable tray drawings EE-034AB and EE-034AC for Reactor Building El. 240', and drawings EE-034AD and EE-034AE for Reactor Building El. 261' indicate that there are cable trays installed In the Drywall for these elevations. The following are the approximate lengths of tray as shown on the drawings. Where actual tray segment lengths are listed on the drawings, the values were conservatively rounded up to the nearest fool. In addition, where cable trays segment lengths are not listed on the drawings, the tray length has been conservatively estimated by scaling the lengths from the drawing. The following era the resulting scaled lengths:

El. 240' 50-ft. (EE-034AC)

Df0- (EE-034AB)

Sub Total 50-t.L El. 261' 40-ft. (EE-034AD) 1-

& (EE-034AE)

Sub Total 130-ft.

Total. 180-ft.

4. To verity the above scaled cable tray lengths, the TRAK 2000 raceway report (Ref. 41 was reviewed for the raceways Identified on the above drawings. The Identified cable trays contain the cables feeding the Reactor Recirculation Pumps. The TRAK 2000 Information for these raceways installed in the Drywell provide the following installed lengths:

2TJ012N 70-FT 2TJO15N 39-FT 2TJO22N 8-FT Total: 19441.

Ifcable lengths are to based on cable tray lengths, this ODTwould estimate a 210-ft total cable tray length.

5. To Investigate the cables Installed between the electrical penetrations and the Reactor Recirculatton Pumps (RCP), and Installed In the abovementioned cable tray, the As-BuIlt Cable Report [Ref. 5] was reviewed. The as-buflt cable reports Identifies the cable Identficatton number, the number of cables, the type of cable, Its racaway's Installed length, the cable's calculated length and Its actual length. The actual length exceeds the cable tray length to allow for free air length. termination length, and actual Installed length. The below'summarizes the Installed cables' types and lengths:

cc: HELMUT R KOPKEISargenfundy@Sorgentlundy 08/11104 G444 PM Subject Cable Inventory for pH Analysis Bob, I've been using your data as Input to the calculation of the pH In the Suppression Pool In Unit 2. Its a nice analysis and has much of the Information I need, but I'd like to confirm a few additional details to properly use the data.

Your data will be used to calculate the formation of HCI by.radlolysis of chlorine-bearing materials. As I understand itLonly the jacketing contains chlorine; the insulation Is made of EP or some other material that does not contain chlorine. Therefor, I need to determine the amounts of jacketing only. The radiolysla -

calculation Is sensitive to depth because radiation Is absorbed as it passes through the materiel. Because of this, besides the total weight of jacketing I also need data which Identify the jacket OD and the Jacket thickness.

The Cable Inventory you prepared concludes that there Is a total of 200 LF of tray in the Drywall which is used for Reactor Recirculation Pump power cables. It also uses a jacket and insulation weight of 6.4 lb per foot for cable In this tray, but doesn't Identify the basis for this unit weight. Your email dated 7120 indicates 1/c 750 MCM cables are used plus a 1/0 ground cable. Is the 6.4 lb per foot weight based on the total insulation and jacketing for three power cables plus one ground cable (i.e.. 600 LF 750 MCM cable and 200 LF 110.cable)? Are there any other cables in the tray?

The Cable Inventory also assumed additional exposed cable equal in weight to the Recirculation Pump power cables. Again. I need to use a.jacket.OD and thickness for the pH calculation. Would this additional cable be power cable or would it include smaller diameter control cable? Perhaps a reasonable assumption would be a mix of both.

I need to get the additional Information for all cables In the cable tray and elsewhere In the Drywall as described above. Your emall dated 7/20 provided the cable OD and the jacketing thickness for 1/c 750 MCM power cable. Please provide similar data for other cables and quantities by type of cable.

I would appreciate inclusion of a summary results table such as the following In your analysis. This would help me understand the data and provide a reference to be used for input to the pH calculation.

Cable Total length Jacket wt Jacket OD.- Jacket thickness 750 MCM power 600 LF xxx lb/kft 1.94 In 110 ml 1/0 ground 200 LF xxx tb/kft x.xx In xxx mill etc.

The final calculation is due to the client on August 24 and must be reviewed and approved before then. I need to receive an updated Cable Inventory to use as Input no later than Monday, August 16 to support the schedule.

Thanks, Jeri 312-269-6234

1) Pool volume is computed as follows: (msp / psp)*2 8 .3 1 68 5 lift3

2) The HI, HCI, 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: Vasis/Vsp where Vba,. 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= 1 0 0 0 g/I. To account for the density in the post-LOCA SP, the concentration from Table 4-3 3

is multiplied by Psp / 1000 g/Il
