1. Purpose and Objective In order to prevent iodine re-evolution following an accident, the pH of the Suppression Pool should be maintained above 7.0. The chemistry of this phenomenon and methods of pH control are discussed in References 5.1 and 5.5.

The Objective of this calculation is to detenrmine the pH of the Suppression Pool following a Loss of Coolant Accident based on the use of Alternative Source Terms as deflned in References 5.4 and 5.6. The pH values are detennined, as a function of time, with and without the addition of the sodium pentaborate in Ihe Standby Liquid Control System. The conditins required to maintain the Suppression Pool at a pH above 7.0 are determined.

2. Methodology and Acceptance Criteria This calculation is based on the methodology developed for the equivalent calculation done for t'he Grand Gulf Nuclear Station, Unit I as revised December 2000. [Ref. 5.1 & 5.2]. The calculation formulas developed in these documents are accepted without independent verification. These references are included in this calculation as Attachments F and G. The accuracy of translation of the equations in these documents into spreadsheet cell formulas is verified by duplicating the Grand Gulf calcutation. This verification is presented as Attachment E and accurately duplicates all of the Grand Gulf results.

As noted in this calculation, injection of sodium pentaborate solution by the Standby Liquid Control System is a required function in order to control post-LOCA pH in the suppression pool, and prevent iodine re-evolution. Based on the worst case beginning of cycle condition, injection should be completed within about. 30 hours after the start of the DBA-LOCA. Therefore, manual initiation is acceptable. Manual initiation of SBLCS is expected early in a DBA-LOCA as a result of emergency operating procedures and severe accident guidelines, particularly for events resulting in fuel damage that would be consistent with AST source terms. Acceptance Criteria: Per the guidance of Appendix.A of Regulatory Guide 1.183 [Ref. 5.6], the Suppression Pool pH should be controlled at values of 7 or greater following loss of coolant accidents.

3. Assumptions/Engineering Judgements

 "    The Suppression Pool is assumed to be well mixed so that the pH at any time can be represented by a single value.
 "    For cable parameters, the cable data presented in Attachment A is used. It includes the exposed termination length of what is in a raceway. As a conservative estimale of the cable lengths in free air, an additional 5% of the raceway's totals are assumed to be in free air. A 10% contingency on the cable surface, reported in Attachment A, is also included. Radiolysis of surface coatings on the steel and concrete surfaces in the Drywell and Containment would not be significant contributors, since the coatings utilize non-chlorinaled polymers.

4. Design Input Cable Data Cable lengths, diameters, and average jacket thickness are developed separately and presented in Attachment A.

Temperature Suppression Pool temperatures are taken from UJFSAR, Rev.15 Figure 14.6.12A. Since this revised curve extends only to 14 hours, the older UFSAR, Rev 14 curve, Figure 14.6-12 was used to extend the data to 278 hours and extrapolate to 720 hours. The older curve gives slightly lower temperatures in the area of overlap and is therefore conservative (Lower temperatures give higher calculated pH values). Extrapolation of the semilog plot is acceptable since the calculated pH is rather insensitive to temperature. At 30 days (720 hours) it requires a 36 FP increase to reduce the pH by 0.1.

CALCULATION No. PM-1056 REV. No. 0 PAGE4 of 15 Sodium Pentaborate mass in SBLC Tank Per Technical Specification SR 3.1.7.7, the minimum B-10 stored in the SBLC tank is 162.7 lbs. In order to prepare this calculation, total boron is needed. The highest vendor supplied enrichment from Reference 5.7., included as attachment H, is 63.5 atom % B-10. For this calculation, 65 atom % B-i1] enrichment is assumed. Since B-10 has an atomic weight of 10.01, this gives 7373 gram-atoms of B-10 and 11,342 gram atoms of total boron. Since the formula of Sodium Pentaborate is Na2B,0Ot6 X10H 20, there are 1134 gram-mols of the pentaborate in the SBLC Tank. This calculation is performed on the pH calculation spread sheet at the top of columns U -Y. Suppression Pool Volume The limiting Tech. Spec. volume [Ref.5.8] is 122,900 cu. ft. from Tech. Spec.

Thfe following, equation, valid during the Early Vessel Release Phase, includes the release during the Gap Release Phase. See analysis in Reference 5.1 (Section 3.1 and Equation 3-1d). Iodine and cesium core inventories are calculated for both beginning and end of cycle (BOC and EOC) conditions (See Attachnent B for a discussion of the assumed BOC conditions). Since EOC conditions result in increased inventory of both acidic (iodine) and basic (cesium) compounds, pH values are calculated for both conditions. For conservatism, the EOC radiation doses are used for the BOC calculation.

Radiolysis of surfthce coatings on the steel and concrete surfaces in the Drywell and Containment would not, be significant contributors, since the coatings utilize nonchlorinated polymers. The calculation of the resulting concentration in the Suppression Pool is based on the equations in Section 3.3 of Reference 5.1 [see Ref. 5.2, Equations 5-1, 5-2, and 5-3]. These equations are in turn based on the following G value for HCI production in Hypalon chlorinated polymer given in Reference 5.5.

CALCULATION No. FM-1056 REV. No.0 PAGE 9 of 15 Effect of Sodium Pentaborate (SBLC) Addition The pH of the suppression Pool can be increased by the addition of Sodium Pentaborale from the Standby Liquid Control (SBLC) System. The limiting value (minimum weight) from Reference 5.7 is 210.6 lbs, but fbr conservative the more limiting value from Technical Specification SR 3.1.7.7 of 162.7 lbs is used. The limiting value is used since it minimizes the number of'moles available for buffering. Addition of Sodium Pentaborate introduces a buffer into the Suppression Pool which will maintain the pool at a pH corresponding to the following equation: [Ref. 5.1, See. 6.1, p. 21]. pH = pK, + logio ([anion] / [acid]) 6-14 with data for K. fitted by the equation K, =(0.0585

7. Summary of Results and ConcJusions The post accident Suppression Pool pH is calculated as a function of time after accident initiation. The results are shown below in Figures 7-1 and 7-2 for Beginning of Cycle (BOC) and End of Cycle (EOC) conditions respectively. These graphs are based on Excel spreadsheet calculations presented in Attachment C (Sheets I and 5). The inputs to the pH calculation of radiation. doses and the Iodine and Cesium inventories are presented in Attachment B.

The BOC (actually early cycle) condition produces the lowest pH and is therefore the limiting case. Without addition of sodium pentaborate from the Standby Liquid Control (SBLC) System, the pH in the Suppression Pool could drop below pH 7 after 30 hours, reaching pH 3.5 at 30 days. Therefore, SBLC addition is required to prevent iodine re-evolution. With timely SBLC addition, the Suppression Pool remains above pH 8 at 30 days (720 hours).

Purpose The purpose of this attachment is to provide a conservative basis for the calculation of Hydrochloric Acid addition to the suppression pool from radiolysis of exposed chloride-bearing materials inside the drywell during post-Loss of Coolant Accident (LOCA) conditions. The primary exposed chloride-bearing materials are the DuPont Hypalon (or Hypalon-like chlorosulfonated polyethylene rubbers from other manufacturers, such as Okonite) jackets typically used on containment power and control cable. Post-LOCA in-containment radioactivity exposure to these materials can lead to radiolytic breakdown with free chlorine radicals available for carryover as hydrochloric acid to the suppression pool by containment sprays or condensation, with resulting decreases in suppression pool pH. Cables in sealed metal conduits can be excluded from consideration, as there is no mechanism for any significant HCI produced to be released through the conduit (even if connections are assumed to leak, the HCI vapor formed is so chemically reactive that no significant amount would remain unreacted and available for release).

2. Background and Approach PBAPS Station Electrical Engineer Dale Shallcross developed a listing of the total drywell exposed cable inventory from the INDMS database. The resulting data on cable types and codes, location and length were tabulated and provided to WGI. Following subsequent WGI discussions with Mr.Shallcross on December 26, 2002, he confirmed the data would be a conservative approximation if an additional 10% of cable area is used to account for any missed cable and ifa 5% free air addition is made. He also provided by fax of that date a listing of cable codes vs. their maximum cable outer diameter. This data for each unit were listed in the following spreadsheets with the formulas shown on the last 2 pages (corresponding to the first and last page of the spreadsheets for each unit).

Mr. Shallcross also indicated that there is no cabling underwater or in the air space of the suppression pool. Hypalon may be used not only as an external cable jacket material, but also as a filler inside the jacket. Therefore, to conservatively account for such Hypalon use and in accordance with the equivalent assumptions used by Grand Gulf in Reference 5.2 of Calculation PM-1056, an equivalent chlorine-containing material thickness of 80% of the cable radius is used, considered as 100% Hypalon. Additional conservatism is provided by inclusion of all cable types as if they are all Hypalon or Hypalon-equivalent jacketed.

3. Results The data was used to develop individual and total cable volumes and the resulting volume-average cable radius [derived as the square root of the quantity (Total Cable Volume divided by pi and the Total Cable Length)]. The Hypalon thickness was then derived as 80% of this average cable radius. The calculations indicate that Unit 2 has the greater surface area of 1,837,364 square centimeters, and Unit 3 has the greater Hypalon average thickness of 0.70514 centimeters. For conservatism, this combination of the worst case from each unit is used.

PBAPS pH Calc., Draft Rev. 0 Attachment B Part 1: Determination of Post-LOCA Drywell/Torus and Suppression Pool Integrated y and 13 Energy, and Suppression Pool Integrated Doses for Suppression Pool pH Determination Part 2: Core Cesium and Iodine Determination

Part 3: Drywell and Torus Gamma Mean Free Path Determination

1. Part I Purpose The purpose of this analysis is to determine Post-LOCA Drywell/Containment and Suppression Pool Integrated y and 13energies, and Suppression Pool Integrated Doses for Suppression Pool pH Determination. This data is used in Attachment C of this calculation to detennine the radiolytic generation of acid input to the suppression pool.

During a DBA-LOCA, analyzed using Alternative Source Terms (AST), radioactivity is released from the reactor, first during a 1/2 hour gap release period, and then during an early in-vessel release period. Activity is then removed froin containment by decay only for conservatism and simplicity.

2. Approach This attachment calculates the total integrated ?yand 13energy released into drywell/containment at specific points in time, and total y plus 13Dose in the Suppression Pool water. For conservatism in this calculation, all activity is instantly distributed into the drywell and containment airspaces. The data is then used by the spreadsheets in Attachment C to calculate the change in the pH of the pool water as a function of time.

Initial activity in the core is taken from Reference 5.11. Release fractions and timing are per R.G. 1.183, Table 1. For simplicity, and because of its negligible effect, no credit is taken for the 121-second minimum anticipated time before the start of gap activity. No credit is taken for natural' deposition or suppression pool scrubbing. This maintains aerosols airborne to conservatively simulate theoretical plateout contributions. In general, significant amounts of plated-out material are likely to be washed into the suppression pool by condensed vapor flow or containment spray. Simultaneously, all non-noble gas releases are assumed to be instantly transported to, and uniformly mixed in, the suppression pool water. The calculation of the dose in the pool water, and the integrated energies from radiation in drywell/containment, parallel each other, up to the point of determining the total integrated y and 13energy released into containment at the specific time-steps used by Entergy in their GGNS Suppression Pool pH Analysis Calculation (No. XC-Q1 111-98013); the basis for this part of the Peach Bottom AST analysis.

t= time (hours) When the above values are obtained for each isotope, the Activity in Containment can be calculated at given times, and subsequently the energy from the activity can be calculated in the following manner: Total Time Integrated Activity in Drywell/Containment at Specific Times (t hours) 2 a,i,,, = ( ') x (1 - eI't ) + A, a(2)1,,,,,= total activity in containment at 2 hours (Ci) a,,,,,,*= total time integrated activity released through 2 hours (Ci-hours) 2= decay constant, variable depending on isotope (hours-') t= time (hours) At this point, the above equation is used to calculate the activity at the given timesteps, due to 7 P3 and radiation and the values are sunmmed for all contributing sources, as used in the GGNS analysis model. Finally, the activity's radiation energy concentration is calculated by dividing over the airspace volume of containment. Subsequently, this data is input into the spreadsheet of Attachment C to calculate the concentration of HCI that results in the pool (due to the release of chlorine from the radiolysis of cables in primary containment), and its contribution to the pH transient. Of additional concern is the formation of Nitric Acid (HNO3), which contributes to the transient calculated in Attachment C, by serving to lower the pH in the pool. Any activity from sources found inunediately in the pool water is a factor in this acid's formation; therefore a dose to the water must also be calculated. Because the noble gas sources stay gaseous and do not mix with the pool water, we need only to consider non-noble gas sources in this calculation. As stated P3 earlier, up to the point of determining the total integrated y and energy released into containment at the specific time-steps, the calculation, of the dose in the pool water, and the integrated energies from radiation in containment parallel each other. As before, the activities at given timesteps are summed for all contributing sources and the radiation energy concentration is calculated. However, the Entergy designed spreadsheet used in Attachment C uses a dose value for its calculation directly to HNO3 concentration, so it was necessary to convert the energy concentration (MeV/cm 3) to dose (Mrad). The conversion factor PM-1056, Rev. 0, Attachment B, Page B-4 of B-14

was detenrined to equal 1.60209E-14 (Mrad/(MeV/cm3)h. When all concentrations were converted to doses, the y and P3 values were sumnmed and input into Attachment C to calculate the concentration of HNO 3 formed, and its contribution to the pH transient. Part 2: Core Cesium and Iodine Determination Cesium and Iodine released from the core during the DBA-LOCA have an impact on suppression pool pH. lodines can contribute to the formation of hydriodic acid, HI, and cesiums contribute to formation of Cesium Hydroxide, CsOH. There is significantly more Cesium available and released from the core than Iodine. Therefore, these materials lead the suppression pool to be basic essentially from the beginning of fission product release. The quantities of Cesium and Iodine, tabulated on page B-14, were taken from the PBAPS Loss of Coolant Accident (LOCA) calculation's attached Source Terms. Part 3: Drvwell and Containment Gamma Mean Free Path Determination Gamma mean free paths in the drywell are used to conservatively assess the size of the contained cloud that will irradiate cable. The determination of these values is perforned in a manner identical to that used for the GGNS assessment. That is, for the drywell, the entire radius of 34 feet from the reactor center to the drywell wall is used, neglecting shielding provided by the vessel and shield.
