Cooper Nuclear Station, Docket No. 50-298, DPR-46 NRC Meteorological Question #1 With respect to statements in Section 4.2 (pages14 and 15) of Attachment I to the license amendment request (LAR) for Cooper Nuclear Station (CNS) dated October 13, 2008 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML082910768), concerning the control room atmospheric dispersionfactors (x/Q values), pleaseprovide reference citationsfor:
the hourly meteorologicaldatafiles, by name, previously submitted andfound acceptable by the U.S. NuclearRegulatory Commission (NRC) and 0       documents confirming the acceptabilityof the specific x/Q values presentedin Table 1 of the October 13, 2008, LAR.
Otherwise, NRC staff notes that Section 3.1.2 of the safety evaluation (SE) associatedwith CNS Amendment No. 196 (ADAMS Accession No. ML030560804) dated February21, 2003, states that the NRC staff had concerns about the quality of the data collectedfrom 1994 through 1998.
The x/Q values presented in Table 3 of the SE associatedwith Amendment No. 196 were based upon the single year of meteorologicaldata resulting in the limiting x/Q values ratherthan the entire 5-year period.In the SE, the NRC staff remarked that the licensee stated that a series of measures were initiatedin 1998 to improve the meteorologicalmeasurementsprogram and the NRC staff recommended that datafrom the improvedprogram be consideredfor use in any future calculations.Therefore,please explain how the hourly datafrom the upgraded meteorologicalprogram compare with meteorologicaldata measuredfrom 1994 through 1998, and demonstrate that use of the 1994 through 1998 data is acceptable.

===Response===
The Control Room Chi-Over-Q (X/Q) values used in the October 13, 2008 License Amendment Request (LAR) are from Calculation NEDC 99-031, Rev. 4, which was submitted to the Nuclear Regulatory Commission (NRC) on September 14, 2001 (NLS2001085) in support of the LAR related to the Design Basis Accident Radiological Assessment Calculational Methodology. This revision used five years of meteorological data for each run (previous revisions used one year of meteorological data for each run and selected the run for the year resulting in the highest values of x/Q). The submittal supported the issuance of License Amendment 187 by the NRC on October 23, 2001.

NLS2009037 Attachment Page 2 of 8 The X/Q values derived from this meteorological data are the basis for the LAR dated September 29, 2005 (NLS2005075) for Application of the Alternative Source Term (AST) for Reevaluation of the Fuel Handling Accident (FHA) Dose Consequences, which was approved by the NRC on September 5, 2006 as Amendment 222. The Control Room x/Q value for the Reactor Building ground level release during the first five minutes is the same as that used in the application approved in Amendment 222.
Regulatory Guide (RG) 1.183, Section 5.3, Meteorology Assumptions, states, "Atmospheric
*dispersion values (x/Q) for the Exclusion Area Boundary (EAB), the Low Population Zone (LPZ), and the Control Room that were approved by the staff during initial facility licensing or in subsequent licensing proceedings may be used in performing the radiological analyses identified by this guide." Use of the current X/Q values was based on this provision of the RG, and the X/Q values submitted previously, as stated in Section 4.2 of the LAR.
NRC Meteorological Question #2 Section 3.1.2 of the SE associatedwith Amendment No. 196 states that use of the diffuse source x/Q values for the CNS turbine building is acceptable on a case-specific basisfor modeling the dispersion of low level (i.e., 10 standardcubic feet per hour) main steam line isolationvalve leakage during a loss-of-coolant accident (LOCA) andfor modeling the dispersion of the 1 percent volume per day leakagefrom the condenserfor the control rod drop accident. Will these and other applicable criteriastill be met in the proposed license amendment? Will the set ofx/Q valuesfor the loss of offsite power (LOOP)case still bound the set ofx/Q valuesfor the non-LOOP case?

===Response===
Yes, the total Main Steam Isolation Valve (MSIV) leakage in the proposed license amendment
(< 212 scfh total for the Main Steam pathway when tested at > 29 psig) is greater than the total MSIV leakage used in the Loss of Coolant Accident (LOCA) dose assessment methodology approved by Amendment 196 (> 46 scfh combined main steam leakage). However, the increased MSIV leakage is still a small amount compared to the large free volume of the Turbine Building (less than 1 percent of the Turbine Building volume per day) and is still many orders of magnitude less than the release for a Main Steam Line Break (MSLB) accident. Therefore, the reasoning used in the Amendment 196 Safety Evaluation (SE) to justify the diffuse release from the Turbine Building remains valid even with the higher MSIV leakage in this proposed license amendment.
The Cooper Nuclear Station (CNS) response to the NRC request for additional information provided in Attachment 1 of Nebraska Public Power District (NPPD) letter NLS2002094 dated September 13, 2002, which is referenced in the Amendment 196 SE, provides a qualitative response explaining why the X/Q values for the Loss of Offsite Power (LOOP) case bound the X/Q values for the non-LOOP case. The X/Q values from the proposed license amendment for the diffuse release from the Turbine Building are only slightly smaller than those listed in Table 3 of the Amendment 196 SE. Therefore, the reasoning provided in the previous respohse

NLS2009037 Attachment Page 3 of 8 remains valid and the set of X/Q values for the LOOP case still bound the set of X/Q values for the non-LOOP case.
NRC Meteorological Question #3 The October 13, 2008, LAR requests approvalfor changes to the CNS technical specificationsto establish a higher leakage limitfor the newly defined main steam pathway and to credit the standby liquid control system for LOCA mitigation. Do changesproposed in the October 13, 2008, LAR introduce any new releasepathways or other changes in the dose scenario that would affect use of the currentlicensing basis x/Q values? If so, please provide the following information or cite references where the information has been previously docketed.
* Inputfiles (electronicfiles for data input into the ARCON96 computer code) and a discussion of assumptions used to generate the x/Q values and summary outputfiles.
These inputfiles should clearly indicate the release height, receptorheight, distance, and direction (with respect to true north)for each release/receptorpairanalyzed.
Figures which support the selection of the inputs and assumptions used to calculate all of the onsite x/Q values. Include a figure of the generalarrangementofplant structures, drawn approximately to scale and showing true north, sufficient to enable the NRC staff to make confirmatory estimates of the selected inputs and assumptions and resultantx/Q values. Highlight the postulatedrelease and receptor locations including control room locations that may experience unfiltered inleakage.

===Response===
No, the proposed changes in this LAR to increase the main steam leakage limit and credit Standby Liquid Control (SLC) for LOCA mitigation do not introduce any new release pathways or changes that would affect the use of the current licensing basis X/Q values. As stated in the response to meteorological question 2, use of a diffuse release from the Turbine Building is acceptable with the higher leakage for the main steam pathway in the proposed LAR. Crediting SLC for LOCA mitigation affects the suppression pool pH and has no effect on the X/Q values.
The EAB and LPZ X/Q values used in the proposed license amendment are essentially the same as the current CNS licensing basis values for a LOCA listed in Table 3 of the Amendment 196 SE for a stack release and the AST FHA values listed in Table 1 of the Amendment 222 SE for a ground level release. The only difference is that the fumigation period for the Standby Gas Treatment system elevated release was changed from the first half hour to the half hour period between 1.3 and 1.8 hours, which is the first half hour of the worst 2 hour exposure in accordance with RG 1.183. However, the fumigation x/Q value used in the AST LOCA analysis is the same as the current licensing basis value. The Control Room X/Q values are different than the current licensing basis values for a LOCA that are listed in Table 3 of the Amendment 196 SE. However, as stated in Section 4.2 of the LAR and the response to meteorological question 1, the revised calculation with these new Control Room x/Q values was previously submitted to the NRC on September 14, 2001. The meteorological data, release points, and receptor locations used in this revised calculation are the same as were reviewed and accepted by the NRC in

NLS2009037 Attachment Page 4 of 8 Amendments 196 and 222. As stated in Sections 4.1.3 and 4.2 of the LAR, the proposed AST LOCA dose consequence methodology includes an unfiltered Reactor Building ground level release during the first five minutes to account for the period of positive reactor building pressurization. The Control Room X/Q value used in this LAR for the ground level release from the reactor building is the same as the current licensing basis X/Q listed in Table 1 of the Amendment 222 SE for the first two hours of the AST FHA.
NRC Meteorological Question #4 Which x/Q values were used for assumed unfiltered inleakage into the control room and why are those x/Q values appropriate?

===Response===
The Control Room x/Q values used for the unfiltered in-leakage are the same as those used for the filtered intake. This is consistent with Section 3.2.1 of the Amendment 222 SE for the AST FHA radiological dose consequences, which states that a single receptor point at the Control Room air intake is used for both unfiltered and filtered inflow and unfiltered in-leakage. The response to question 3 on page 49 of Attachment 1 to the CNS AST FHA submittal dated September 29, 2005 (NLS2005075) provides additional information on the unfiltered Control Room in-leakage and the relationship to the Reactor Building release points. The AST LOCA dose consequences methodology uses the same total unfiltered leakage and the same Control Room XQ for the Reactor Building release, during the first five minutes, as the AST FHA.
Although the AST LOCA also uses Control Room X/Q values for the elevated and Turbine Building release points, the same reasoning applies to these as was used for the Reactor Building release points in the CNS AST FHA submittal. Therefore, use of a single receptor point at the Control Room air intake for both unfiltered and filtered inflow and unfiltered in-leakage is also acceptable for the AST LOCA radiological dose consequences.

NLS2009037 Attachment Page 5 of 8 NRC Accident Dose Consequence Question #1 Page I of the LAR dated October 13, 2008 (ADAMS Accession No. ML082910768) states that the requested license amendment represents a "selective scope" applicationof the alternative source term (AST) at CNS," however, the LAR includes a reanalysisof the design basis LOCA using the AST, commensurate with the regulatoryposition 1.2.1, "FullImplementation," of, Regulatory Guide (RG) 1.183, "AlternativeRadiologicalSource Terms for EvaluatingDesign BasisAccidents at NuclearPower Reactors." Therefore, please explain why selective implementation, as opposed to full implementation, of the AST is requestedfor CNS.

===Response===
CNS used RG 1.183 Regulatory Position 1.2.2 (2), selective scope, because we are only requesting implementation of AST-LOCA. We are not requesting implementation of the Main Steam Line Break or Control Rod Drop accidents at this time. Regulatory position 1.2.2 of RG 1.183, "Selective Implementation" states, in part, "Selective implementation is a modification of the facility design basis that" ... "or (2) entails re-evaluation of a limited subset of the design basis radiological analyses." (Emphasis added). This is consistent with our previous LAR for Application of the AST to Reevaluation of the FHA Dose Consequences, NLS2005075, dated September 29, 2005.
NRC Accident Dose Consequence Question #2 Analysis ALION-CAL-NPPD-3236-002, Rev. 1, as included in Enclosure I to the October 13, 2008, submittal, states that dose to the control room occupants due to direct shine was not calculated in the submitted analysis; instead it was calculated in the analysis NEDC 05-045, "LOCA Shine." Therefore, please eitherprovide NEDC 05-045, or thoroughly explain how the Rev. 1 direct shine dose to the CNS control room of 0. 319 rem total effective dose equivalent was calculated,as reportedon page 8 of Enclosure 1 to the October 13, 2008, LAR, NEDC 0 7-082, Rev. 2. Also, please provide all additionalinformation needed to characterizethe direct shine dose sourcesfollowing the postulatedLOCA, includingplume location, concentration,and orientationwith respect to the CNS control room.

===Response===
A copy of Calculation NEDC 05-045, LOCA Shine, is included as an enclosure to this response.
No other additional information is needed.
NRC Accident Dose Consequence Question #3 Page 16 of analysisALION-CAL-NPPD-3236-002, Rev. 1, states the following.
The no holdup (no mixing) assumption is included in the input by setting the fraction retained,Frac, within the volume in a unit of time at less than 0.1% and then solving for the reactorbuilding volume from the transientexhaust equation shown below.

NLS2009037 Attachment Page 6 of 8 Please explain how it was determined that a retentionfraction of 0. 1 percent was sufficiently low enough to model, or accuratelysimulate, no mixing.

===Response===
In calculation NEDC 05-045, the value of 0.06% was actually used, so that a rounded value for the Reactor Building volume of 200 ft3 could be used. The analysis examined the effect on the EAB Total Effective Dose Equivalent (TEDE) dose. As shown in Table 6-1 of the report, the EAB TEDE dose is dominated by the leakage from containment to the Reactor Building and the MSIV leakage directly to the environment. The latter effect is not a function of the no holdup assumption for the Reactor Building. As shown in the figure below, even with a 5% retention for the worst two hour EAB TEDE dose due to leakage through the containment to the Reactor Building to the environment, the dose only varies in the third significant figure. By using the 0.1%, the change, in dose estimate was in the fourth significant figure. The figure below illustrates that a higher value such as 1% could have been utilized; however to be more conservative the lower value of 0.1% was used. Note that the no mixing assumption does affect the EAB dose due to Engineered Safety Feature (ESF) leakage as it passes through the Reactor Building. However, ESF leakage would be in proportion to the containment leakage pathway which is approximately three times larger.

NLS2009037 Attachment Page 7 of 8 NRC Accident Dose Consequence Question #4 Page 26 of analysis ALION-CAL-NPPD-3236-002, Rev. 1, states that the lower bound of the uncertainty in the ControlRoom Emergency FiltrationSystem intake flow was used to minimize the removal rate of radionuclidesfrom the control room following isolation. Please explain how it was determined that this treatment was indeed conservative, and that doing this does not inadvertentlyslow the buildup of activity in the control room, thereby reducing the accumulated dose.

===Response===
This issue concerns the choice of the lower bound for the Control Room filtered inflow, and the potential for radionuclide buildup. In order to assess this concern, cases were run and plots were made by varying the Control Room filtered inflow rate and checking this against the TEDE doses for the lower, nominal and upper bound filtered intake flows. Table 6-1 of the report shows that the MSIV leakage path is the most important component of the Control Room dose, hence that path was chosen for examination. The table below illustrates the effect of changing the intake flow on the control room TEDE dose. It can be seen that the lower bound value yielded the highest calculated doses for the Control Room TEDE. Based on the flowrate comparison, the lower bound flowrate was selected as the most appropriate for maximizing the estimated dose.

NRC Accident Dose Consequence Ouestion #5 Pleaseprovide a direct comparison of the elemental iodine removal efficiencies calculatedfor a condenser in NEDC-31858P-A, Rev. 2, and those calculatedfor CNS condenser.Also, please explain andjustify any deviations or extrapolationsfrom the methodology presented to calculate elemental iodine removal in the condenser in NEDC-31858P-A, Rev. 2.

===Response===
NEDC-31858P-A Rev.2, Appendix C does not contain calculated values of the elemental iodine removal efficiencies. No deviations or extrapolations from the methodology presented in NEDC-31858P-A Rev. 2, Appendix C for the calculation of elemental iodine removal efficiency have been taken. The main condenser effective filter efficiencies (1-C/Cm) are summarized in Alion Calculation ALION-CAL-NPPD-3236-002, revision 1, on page A36, as shown below.

Description:==

PURPOSE:
Phe purpose of this calculation is to determine the 30-day shine dose to a control room (CR) operator following a design
)asis LOCA. The following shine contributors are addressed: Outside Cloud, Reactor Building, Core Spray Line, JREFS Filter, and Drywell. The analysis is performed based on Alternate Source Term (AST) methodology. The results will be fed back into the AST LOCA calculation (NEDC 07-082) to give total TEDE dose. This calculation has been 3repared as Status 3 and will be as-built upon NRC approval of the AST methodology.
RESULTS AND CONCLUSIONS:
Phe 30 day control room exposure results (from Attachments 1 to 5) are as follows:
: 1. Outside Cloud             15.9 millirem
: 2. Reactor Building          0.004 millirem                                                                        I
: 3. Core Spray Line           28.4 millirem
: 4. CREFS Filter               245.7 millirem
: 5. Drywell Total 0.0005 millirem 290.1 millirem (without equilibrium daughters)
I Total    319.1 millirem (adds 10% for equilibrium daughters) USE THIS TOTAL Phe radiation exposure predominantly comes from the CREFS filter. The total exposure is a small fraction of the limits
,iven in 10 CFR 50.67(b)(2)(iii). Results are to be fed back into the AST LOCA calculation (NEDC 07-082) to give total PEDE dose.

Page: 5 of 7 NEDC:     05-045 Rev. Number:       1 Nebraska Public Power District DESIGN CALCULATIONS SHEET PURPOSE:
The purpose of this calculation is to determine the 30-day gamma shine dose to a control room (CR) operator following a design basis LOCA. The following shine contributors are addressed: Outside Cloud, Reactor Building, Core Spray Line, CREFS Filter, and Drywell. The analysis is performed based on Alternate Source Term (AST) methodology.
The results will be fed back into the AST LOCA calculation (NEDC 07-082) to give total TEDE dose. This calculation has been prepared as Status 3 and will be as-built to Status 1 upon NRC approval of the AST methodology.
ASSUMPTIONS:
Each of the shine contributors is described in its own attachment to this calculation, and the assumptions applicable to each contributor are identified in that particular attachment. In general, the dose point location in the, control room from all shine sources is taken to be the center of the Reactor Operator desk, as shown on drawing CNS-BLDG-442, because it is closer to the reactor building compared to the BOP station. In the case of CREFS shine, which is the largest shine contributor, the distance used was verified to not be unconservative with respect to where a BOP station operator would sit. Another general assumption that is very conservative is Occupancy Factor. Regulatory Guide 1.183 allows use of a 0.6 factor between 1 and 4 days, and a 0.4 factor after 4 days, to account for control room personnel changes. In cases where the source term is developed by directly using control room X/Qs, as in the case of CREFS shine, the source term already contains implicitly reduced occupancy factors because they are contained in the X/Qs. For other shine sources, this calculation conservatively imposes no reduced Occupancy Factors. As discussed in Attachment 4 (MAIN), equilibrium daughters will increase the shine dose by 8%. Since doses from shine sources were calculated without equilibrium daughters, the total "un-daughtered" dose is increased by 10% to conservatively account for this effect.
METHODOLOGY:
Each of the shine contributors is described in its own attachment to this calculation. In general, each attachment is organized into five parts: 1) General Notes, 2) RadTrad Output, 3) MicroShield Input, 4) Main (geometry and dose results), and 5) MicroShield Output. The specific methodology applicable to each shine contributor is described in each attachment. In general, the AST LOCA calculation (NEDC 07-082) determines post-LOCA control room dose from inhalation and control room cloud shine. The calculation also develops isotopic source terms for the five additional shine contributors mentioned above.
The LOCA shine calculation (NEDC 05-045) applies the source terms, develops a conservative model, and computes the shine doses to the control room from each shine contributor using the computer code Microshield v5.05. This code is classified Level 2 (for use in critical applications), as shown on the CNS IT website, and has received a completed Level 2 Software Quality Assurance Plan (SQAP) review (reference 1), in accordance with CNS procedure 11.4.2. Design inputs whose status is not "as built" have 5

Page: 6 of 7 NEDC:     05-045 Rev. Number:       1 been verified to not be calculation-critical to the information it contains, have been substantiated by other "as-built" information, and/or verified to have not substantially changed since original plant construction.
REVISION 1:
NEDC 05-045, Revision 0, was based on NEDC 07-082, Revision 0, "Radiological Dose Analysis for a Loss of Coolant Accident (LOCA) at Cooper Nuclear Station. NEDC 07-082 assumed an aggregate MSIV leakage rate of 200 scfh, and took credit for particulate and elemental deposition in the Main Steam Line. NEDC 05-045, Revision 1, is based on NEDC 07-082, Revision 1, which assumed an aggregate MSIV leakage rate of 300 scfh, removed credit for particulate and elemental deposition in the Main'Steam Line, and developed a condenser model based on NEDC 31858P-A (reference 2).
As a result of these changes to the, the corresponding changes to the individual Control Room shine contributors are as follows:
NEDC 05-045 CR Shine Contributor                             Revision 0            Revision 1
: 1. Outside Cloud                                  15.1 millirem        15.9 millirem

Drywell                                       0.0005 millirem       0.0005 millirem Total (without equilibrium daughters)             139.4 millirem       290.1 millirem Total (with 10% for equil. daughters)             153.3 millirem       319.1 millirem The Outside Cloud contributor increased slightly, as expected. The Reactor Building and Drywell contributors increased slightly, but below the number of significant digits reported in this calculation. The Core Spray Line contributor did not change from NEDC 05-045 Revision 0, because in the RADTRAD AST LOCA model (NEDC 07-082), the entire accident source term is conservatively assumed to be transported to the Suppression Chamber and not affected (or reduced) by MSIV leakage. Therefore, the AST LOCA RADTRAD compartment inventory output for the Suppression Chamber, used as input for the Core Spray Line case did not change. The CREFS Filter shine contributor was the most significant change.

Page: __ofA NEDC: 05-045 Rev. Number:        1-CONCLUSION:
The 30 day control room exposure results (from Attachments 1 to 5) are as follows:
: 1. Outside Cloud               15.9 millirem
: 2. Reactor Building            0.004 millirem
: 3. Core Spray Line             28.4 millirem
: 4. CREFS Filter                245.7 millirem
: 5. Drywell                     0.0005 millirem Total 290.1 millirem (without equilibrium daughters)
Total 319.1 millirem (adds 10% for equilibrium daughters)
USE THIS TOTAL The radiation exposure predominantly comes from the CREFS filter. The total exposure is a small fraction of the limits given in 10 CFR 50.67(b)(2)(iii) (reference 3), which states:
Adequate radiationprotection is provided to permit access to and occupancy of the control room under accident conditions without personnel receiving radiationexposures in excess of 0.05 Sv (5 rem) total effective dose equivalent (TEDE)for the durationof the accident.

See Design Inputs this calculation Procedure 3.4.7 Rev. 29 NEDC 31858P-A Summary Of Design Verification (Attach Additional Sheet(s) If Needed):
The only changes to this calculation from Rev 0 was due to an increase in the aggregate
.leakage rate of the MSIV from 200 to 300scfh and eliminated the credit for deposition in the Main Steam Line. This also included a condenser model for filter deposition based on NEDC 31858P-A. This calculation meets the requirements of the current revision of Procedure 3.4.5 for revising design calculations. Microshield values changed based on the changes to MSIV leak rate and changes of in assumptions on deposition previously credited in the main steam lines and condenser.
Conclusions (Attach Additional Sheet(s) If Needed):
The changes to the calculation provide higher doses than Rev 0 and this calculation met the requirements for implementation of the revision. Therefore, it should be implemented.

NEDC 05-045 Rev. I                                                       Attachment 1                                                               Page 1l 1 - Outside Cloud Shine - General Notes 1 Table 1-1 input is taken from Attachment I within Attachment 1 of calculation NEDC 07-082 (LOCA calc).
2 Table 1-2 manipulates input data from Table 1-1 to fit the geometry of the specific situation being considered.
Cumulative isotopic activities (Ci) released at various times are given in the Alion results. This table combines three separate computations. The first is the computation of isotopic release rate (Ci/sec). For each time interval, the average release rate is computed by taking delta isotopic activity released (Ci) and dividing by delta time (h) and dividing by 3600 (sec/h) to give Ci/sec.
The second computation takes the X/Q (sec/m3) (see Table 2-13 in the LOCA calc) for that time interval and multiplies it by the release rate (Ci/sec) to give concentration in Ci/m3. X/Q's are very conservatively selected by time, by release location, and by position. By time, the worst X/Q for the time interval is selected. By location, the worst X/Q at the CR is taken, irrespective of actual release point.
By position, X/Qs are themselves computed to represent cloud centerline concentration. In actuality, the concentration falls off exponentially from plume centerline (RG 1.145). This analysis conservatively uses the cloud centerline concentration at the CR intake.
The third computation takes the concentration and multiplies it by the volume (m3) being modeled, to give total Curies occupying that volume. This ensures a conservatively large cloud inventory, for example, by not placing curies that have been released too far away (as in a semi infinite cloud), when, in fact, cloud geometry could preclude that from happening.
800 feet is selected as cloud radius and cloud height because a sensitivity study on radius showed that 99% of the maximum dose is reached as the radius is increased to 740 feet. The 800 foot values used correspond to between 1 and 4 mean free paths distance for 0.2 to 2 MeV gammas in air, which technically validates this assumption. The volume of a cylinder whose radius and height are 800 feet is 4.555E7 m3. As a check on conservation of curies, the total cloud inventory (Curies) just computed is compared against the total inventory that has been released up until now. It shows that the computed cloud inventory is high by a factor of 200 at 0.5h and 35 at 2h. The reason for the conservatism is that the cloud is assumed to be at the centerline concentration throughout, rather than at an exponentially average concentration. However, this conservatism is being retained.
All three computations are done as one, but have been described here separately to facilitate understanding. Let's see an example to see how it all works. Take the 0.5h time interval and the Cs-134 isotope. From Table 1-1 the inventory at 0.5h is 2.455 curies, so during the first time interval the average release rate is 2.455 Ci / 0.5h x 1h/3600s. The example chooses to not simplify until the end in order to show all the factors used in the computation. The cloud concenrtation is obtained by multiplying the release rate by the X/Q (sec/m3), which is given in Table 2 as 4.15E-3. So, then the cloud concentration.= 2.455 Ci / 0.5h x 1h/3600sec x 4.15E-3 sec/m3.
Finally, multiplying the cloud concentration by the cloud volume gives the cloud inventory. So, the cloud inventory = 2.455 Ci / 0.5h x 1h/3600sec x 4.15E-3 sec/m3 x 4.555E7 m3 = 2.58E+02 Ci. This matches Table 1-2.

: 1. For extreme conservatism, the Outside Cloud is modeled as a large cylinder extending upward from the control building roof. Use a cylinder radius approximately 20 times the largest above equivalent radius (i.e., roof), say 800 feet, and a height of also 800 feet. This begins to substantially approach an infinite cloud in size. A sensitivity study on radius showed that 99% of the maximum dose is reached as the radius is increased to 740 feet. The 800 foot values used correspond to between 1 and 4 mean free paths distance for 0.2 to 2 MeV gammas in air, which technically validates this assumption.
: 2. Conservatively use an end cyl model to put source nearest the dose point.
: 3. Conservatively assume that the dose point is on the cylinder axis.
: 4. Assume a uniform cloud concentration within the cloud itself within a given time period, based on the highest CR X/Q for that time period. This is extremely conservative because plume centerline concentrations are used to specify the X/Q factors used in typical dose analyses, whereas, actual concentration falls off exponentially from plume centerline (RG 1.145).
: 5. MicroShield calculates a constant dose rate (mR/hr) for each time interval from concentrations that based on the average release (Ci/sec) for that interval and the highest X/Q for that interval (sec/m3). For time intervals before the time at which the peak dose rate occurs, a bounding approach is used which selects the highest dose rate for the interval. This is conservative because it takes the bounding value for the entire interval. For time intervals after the peak dose rate, a linear average is used, which is conservative since the dose rate drops off exponentially, rather than linearly.

: 1. Model the RxB as a cylinder having equal volume.
: 2. Use an end cyl model to put source nearest the dose point; in this configuration the cylinder turned on it's side. It's equivalent diameter is based on equal face area (see above). Cylinder "height" is RB N-S dimension.
: 3. Conservatively assume that the dose point is on the cylinder axis.
: 4. The North RxB wall is 1.5 feet thick (about half) and 3.0 feet thick (about half). For conservatism, use 1.5 feet.
: 5. In order to simplify the model, all the floors between RxB basemat and El 1001 do not credit horizontal shielding from the floors. This counts off-axis elevations, which is very conservative. Same thing for vertical shielding (e.g., walls, including drywell), which very conservatively counts off-axis locations. It also very conservatively counts distant souces that would otherwise be shielded.
: 6. CB south wall between 903 and 918 is modeled as 2 feet instead of 1.5 feet in order to simplify the model. This is acceptable because the contributions would be from Source that is off-axis and would contribute only a small amount, due to floor and wall shielding.
: 7. For time intervals before the peak dose rate (see graph), a bounding approach is used, selecting the highest dose rate for the interval. For time intervals after the peak dose rate, a linear average is used, which is conservative since the dose rate drops off exponentially.

NEDC 05-045 Rev. 0                                                       Attachment 3                                                                  Page 1 3 - Core Spray Line Shine - General Notes 1 Table 3-1 input is taken from Attachment I within Attachment 1 of calculation NEDC 07-082 (LOCA calc).
2 Table 3-2 manipulates input data from Table 3-1 to fit the geometry of the specific situation being considered.
Since Table 3-1 gives activity inventories (Curies) to the suppression pool, the average activity concentrations (Ci/ft3) are conservatively computed by dividing the inventories by the minimum suppression pool volume less 5%, given in the MAIN section (page 5) as 83,485 ft3.
Table 3-2 takes these concentrations and applies them to CS Line Segment #1, which is located between RB floor elevations 903'-6" and 931'-6". From the MAIN section (page 5), the pipe ID is 1 ft and the pipe length is 30 ft, which gives a volume (computed here) of 23.56     ft3.        To obtain activity inventories (Curies) of CS Line Segment #1, the concentrations are multiplied by the pipe volume just calculated.
In summary, Table 3-2 activity inventories (Curies) in CS Line Segment #1 are computed by taking the suppression pool inventories from Table 3-1, dividing them by 83,485, and multiplying them by           23.56 Similarly, Table 3-3 focuses on CS Line Segment #2, which is located between RB floor elevations 931'-6" and 958'-3". The activity concentrations are the same as described earlier for Segment #1, however, the length is different. From the MAIN section (page 5),
the pipe ID is 1 ft and the pipe length is 50 ft, which gives a volume (computed here) of         39.27 ft3.           In summary, Table 3-3 activity inventories (Curies) in CS Line Segment #2 are computed by taking the suppression pool inventories from Table 3-1, dividing them by 83,485, and multiplying them by               39.27 3 Table 3-1 is sorted by RadTrad sort #. Table 3-2 is sorted by MicroShield iso # by re-sorting Table 3-1.

: 1. Assume the radionuclides released to the suppression pool. are evenly distributed in the pool.
: 2. Maximize the concentration in the water by conservatively neglecting the volume of the reactor coolant in the RPV, reactor coolant piping, and CS piping. Conservatively use the low suppression pool water level at lowest of uncertainty band. This is much less than the minimum value in USAR Table V-2-1 (or XIV-5-4), so is therefore very conservative.
: 3. No credit is taken for radioactive decay from the suppression pool to to CS line in question.
: 4. CS line routing is given on isometric drawing 2602-2. The portion of CS piping below RxB elevation 903'-6" is assumed to contribute neglegibly to the CR dose because of two factors. First, the north reactor building wall below elevation 903'-6" is greater than 4 feet thick (CNS-BLDG-432, 433), which is significantly greater than the 1'-6" thick wall that conservatively will be used in the model above 903'-6". Second, the floor slab thickness at elevation 903'-6" is.1'-9" thick (4239), which reduces the dose contribution from piping below 903'-6" to a small fraction of the dose from piping above 903'-6", due to the greater attentuation and greater distance.
: 5. The North RxB wall is 1.5 feet thick (about half) and 3.0 feet thick (about half). For conservatism, use 1.5 feet.
: 6. For CS Line Segment #1 (between El. 903'-6" and 931'-6"), conservatively assume that the line is the full floor-to-floor slab distance long and the dose point is on the cylinder end plane. No credt is taken for shielding from the floor slab at El. 931'-6".
: 7. For CS Line Segment #2 (between El. 931'-6" and 958'-3"), assume that the line is a straight horizontal pipe 45 feet long (full run length) in E-W direction (conservatively neglects self-shielding due to skewed angle), and the dose point is on the cylinder midplane and at the same elevation (conservatively neglects additional shielding thickness due to skewed angle).
: 8. Conservatively neglect CR floor slabs.
: 9. For time intervals before the peak dose rate (see graph), a bounding approach is used, selecting the highest dose rate for the interval. For time intervals after the peak dose rate, a linear average is used, which is conservative since the dose rate drops off exponentially.

: 1. Use RO desk as dose point. The distance to the BOP station (position behind the BOP desk) is about 5 inches closer than the distance tothe RO station (position behind the RO desk); however, it is exactly equal to the distance to the-RO desk (center).
Therefore, for conservatism, the RO desk (center) is used for the dose point for this source, since the RO station is used as the dose point for the remaining shine sources due to its greater proximity to each of the sources.
: 2. Assume that radionuclides are uniformly distributed in CREFS filter.
: 3. Assume that the CREFS filter is a homogeneous composition of charcoal and air. Conservatively assume that it is 60% air, based on VM 1682 (see Filter worksheet).
: 4. Assume that the CREFS filter is just a single (not stacked) NUCELL module. This is conservative because it allows for less self.
shielding due to the charcoal itself, yet is not overly conservative since amount of self-shielding from charcoal and air is small.
: 5. Assume that CREFS filter can be approximated as a square cylinder having equal volume. Use an end cyl model with dose point on axis for conservatism.
: 6. Conservatively neglect shielding from structural steel members in the adsorber tray and CREFS filter housing.
: 7. Conservatively neglect shielding from structural steel members in the control consoles and cabinets.

For example, a radionuclide in the source term list may not simply decay and disappear, but decay into another radionuclide that decays and contributes to dose. This is the case for four daughter radionuclides (Ba-1 37m, Pr-144, Rh-1 03m, Rh-1 06) in the source term list used for AST LOCA shine. To exclude or include daughters is a user-selected option in MicroShield. The following results include equilibrium daughters.

5 - Drywell Shine - MAIN
: 1. Model the drywell as a cylinder whose bottom face is at elevation 931'-6" (dwgs 2061, 2066) and whose top face is approximately at elevation 991'-6" (dwg 2066), for a length of 60 feet; and whose diameter is 35'-1" (CBI dwg 1); for simplicity use 35 feet. The reason that the bottom face is set at 931'-6" is because the floor extends all the way to the control room, providing considerable "double' shielding compared to just the RxB wall. This makes contributions from sources below 931'-
6" negligible by comparison to those above. Furthermore, since total curie inventory is used in the dose analysis, placing the entire inventory above El 931'-6" is very conservative.
: 2. For simplicity, the shielding afforded by the reactor vessel is conservatively neglected.
: 3. Between these elevations the drywell shell ranges in thickness between 3/4 inch and 2-5/8 inches. For conservatism use 3/4 inch. The air gap is neglected, which conservatively moves the dose point closer by 2 inches.
: 4. Conservatively assume that the dose point is on the cylinder midplane.
: 5. The North RxB wall is 1.5 feet thick (about half) and 3.0 feet thick (other half). For conservatism, use 1.5 feet.
: 6. In order to simplify the model, all RxB floors between El 903'-6" and El 976'-0", inclusive, are very conservatively assumed to not provide any shielding. This credits sources far off of midplane elevations, which is very conservative. Same thing for RxB walls, which very conservatively credits distant souces. Same thing for drywell floors, walls, and structures. This is an extremely conservative, but simplifying assumption.
