WSES-FSAR-UNIT-312.2-112.2RADIATION SOURCES 12.2.1CONTAINED SOURCESThe radiation sources used for the design and analysis of the shielding requirements are based on thedesign of plant operation including full power operation, shutdown conditions, refueling operations, and for various postulated accidents. They include the neutron and gamma fluxes outside the reactor vessel, the reactor coolant activation, fission and corrosion product activities, deposited corrosion product sources on reactor coolant equipment surfaces, spent fuel handling sources, and postulated core meltdown sources.

In addition, radiation sources for various auxiliary systems are also tabulated.

12.2.1.1Reactor Coolant Fission and Corrosion Product ActivityThe activity utilized for shielding calculations is shown in Table 11.1-2.

The basis for the above reactor coolant radioisotope concentrations is specified in Table 11.1-1, and themanner in which the concentrations have been derived is given in Subsection 11.1.1.1.12.2.1.2Neutron Fluxes Outside the Reactor Pressure-VesselThe maximum neutron spectra during full power operation, divided into 10 energy groups, for points on thetop and bottom of the reactor pressure vessel along the core centerline, and a point on the side of the vessel adjacent to the maximum axial power, are shown in Table 12.2-1. The neutron spectra in this table include the neutrons scattered from the concrete cavity wall and are used to determine the thickness of the primary shield wall.To determine the neutron flux streaming up the annulus between the reactor vessel and the reactor vesselcavity wall, a better definition of the neutron spatial and angular fluxes emergent from the vessel is developed by the computer program DOT(1).The calculation utilizes S 4 quadrature, 22 neutron energy groups, and 16 axial intervals from the corebottom to the upper guide structure. A vacuum boundary is used at the outer radius.The DOT generated data, summarized for convenience in the form of neutron leakage rates from axialintervals spaced along the vessel surface, is shown in Table 12.2-2. The equivalent scalar fluxes can be obtained by division of the leakage rates in the Table 12.2-2 by the surface area of the region.12.2.1.3Gamma Fluxes at Full Power OperationThe maximum gamma spectra during full power operation, divided into 14 energy groups, for points on thetop and bottom of the vessel along the core centerline, and a point for the side of the vessel adjacent to the maximum axial power, are shown in Table 12.2-3.

WSES-FSAR-UNIT-3 12.2-2 Revision 14 (12/05)12.2.1.4 Reactor Coolant N-16 Activity(DRN 03-2066, R14)

The N-16 activity in the reactor coolant which determines the shielding requirements for the secondary shield wall and portions of the Chemical and Volume Control System (CVCS) is discussed in Subsection 11.1.3.1. The N-16 activity at various points in the primary system, as well as the CVCS, is determined from the given activity at the reactor outlet nozzle, taking into account the decay due to the transit time between the nozzle and the point of interest as calculated on the basis of the maximum flow rate and

changes in density caused by cooling. (DRN 03-2066, R14)12.2.1.5 Reactor Coolant System Sources at ShutdownFollowing shutdown, residual radiation from the Reactor Coolant System is due to fission product decay gamma radiation emanating from the core; material activation sources, radioactive corrosion products which have deposited on surfaces, and the fission and corrosion products in the reactor water. The reactor vessel maximum decay gamma spectra, divided into eight energy groups for various times after shutdown, are shown in Table 12.2-4 for a point on the side of the vessel adjacent to the maximum axial

peak.The material activation spectra at the same location and decay time is shown in Table 12.2-5. The material activation sources include contributions from the vessel wall, barrel, shroud, and primary coolant water. Activation of the vessel insulation and supports is considered and evaluated on the basis of the fluxes computed to exist in the annular cavity space during full power operation. The fission and corrosion product reactor coolant inventory assumed to be present for shutdown is that specified in Table 11.1-2, corrected for decay up to the point in time of interest.

The activity of radioactive crud and its thickness on Reactor Coolant System surfaces have been evaluated using data from six pressurized water reactors. For the circulating crud, the observed activities were compared to activity values recommended for design by the Draft ANSI N237 Source Term

Specification, 1976. (DRN 03-2066, R14)(DRN 03-2066, R14)

Table 11.1-10 shows the expected maximum specific activities for deposited corrosion products. The residual activity due to deposited corrosion products is evaluated with the assumption of a thickness of

0.16 mg. crud/cm 2 for steam generator tubing and a 1.5 mg. crud/cm 2 for piping and system crud level. (DRN 03-2066, R14)The current FSAR design basis source terms are based on draft ANSI standard N237. Extended Power Uprate used ANSI/ANS-18.1-1999 as the basis for source terms. An evaluation of the two source terms and the change in the flux-to-dose conversion factors between ANSI 6.1.1 1977 and ANSI 6.1.1 1991 indicate that the EPU source terms are bounded by the current FSAR design basis source terms. (DRN 03-2066, R14)12.2.1.6 Pressurizer ActivityThe liquid section of the pressurizer has source terms due to plateout of radioactive crud plus dispersed fission and corrosive product activity in the water.The maximum deposited activity for the liquid section, assuming a crud film thickness of 1.5 mg. crud/cm 2 , is derived from the values of Table 11.1-10. As an upper limit, the liquid section will have WSES-FSAR-UNIT-3 12.2-3 Revision 309 (06/16) dispersed fission and corrosion product activity equal to the primary coolant activity with one percent failed fuel specified in Table 11.1-2.

The activity in the steam section is due to the bu ildup of the gaseous fission products Xe and Kr from one percent failed fuel. This activi ty is shown in Table 12.2-6.

12.2.1.7 Contained Sources in Other Plant Systems The source intensity in equipment and pipelines handling radioactive fluids is det ermined from activity in the reactor water by considering the processes t hat the reactor water has undergone prior to entering equipment and piping (dilution, filtering, demi neralization, delay, change of phase, etc.)

In all cases the process or combination of proce sses leading to the highest activity is considered for conservatism. The maximum inventory of activity in the various components of the Chemical and Volume Control System, Boron Management System, Fuel P ool System, Safety Injection System and Waste Management System are listed in Tables 12.2-7, 12.

2-8, 12.2-9, 12.2-10 and 12.2-11, respectively.

12.2.1.8 Spent Fuel and Spent Fuel Pool The maximum and expected fission and corrosion product activi ties in the spent fuel pool are specified in Table 11.1-17.

The source terms employed to determine the minimu m water depth above spent fuel and shielding walls around the spent fuel pool, as well as shielding of the s pent fuel transfer tube, are given in Table 12.2-12.

The activities shown in that table are equilibrium co re activities based on 105 percent of full power core conditions.

(LBDCR 16-016, R309)

The spent fuel pool contains greater than 8 cores as described in Subsection 9.1.2. (LBDCR 16-016, R309)

(DRN 99-2362, R11)

To size the shield for the transfer tube, the hottest el ement is assumed to be trans ferred. Its activity is that computed from the assumption of a homogenous core inventory (Table 12.2-12) and an overall peaking factor of 1.80. (DRN 99-2362, R11) 12.2.1.9 Accident Sources (DRN 03-2066, R14)

The accident source terms which are employed to determine shielding requirements for emergency accessways and containment shielding, as well as potential doses to equipment inside containment following a loss-of-coolant accident (LOCA) are shown in Table 12.2-13. Table 12.2-13 assumes a release to containment of the activity stated in TID 14844 (2), namely 100 percent noble gasses, 50 percent halogens, and 1 percent rema ining fission product inventory.

The accident sources for the main control room are shown in Table 15.6-18. (DRN 03-2066, R14)

The accident sources for the Safety Inject ion System are shown in Table 12.2-10. (LBDCR 13-009, R307) 12.2.1.10 Low Level Radioactive Waste Storage Facility The Low Level Radioactive Waste Storage Facilit y (LLRWSF) was added as part of LDCR 95-0059 for storage of radioactive waste awaiting disposal.

The radiation protection design of the LLRWSF, in terms of shielding and dose estimates is based upon the dose rates of the waste containers in the facility when the facility is filled to capability. Table 11.4-11

includes anticipated waste volumes by type for a fully loaded facility. The design basis radiation levels for

the wastes to be stored in the facility are bas ed on Waterford 3 historical source terms. (LBDCR 13-009, R307)

WSES-FSAR-UNIT-3 12.2-4 Revision 307 (07/13)

(LBDCR 13-009, R307)

The radiation shielding configuration of the LLRWSF is designed in accordance with the dose rate criteria per 10CFR20, FSAR and site procedures for both the site boundary and for restricted areas. The nearest

site boundary to the LLRWSF is River Road which is approximately 980 ft away. The facility is designed so that the maximum offsite dose rate at the si te boundary from the waste stored in the LLRWSF will be maintained < 0.05 rem/yr which is 10% of the allow able. The restricted area is the area surrounding the LLRWSF which will be controlled by the Radiation Protection Group for purposes of protection of

individuals from exposure to radiation and radioactive materials. The facility is designed so that the maximum dose when the facility is fully loaded at approximately 60 ft. away is 0.3 mrem/hr.

The projected waste containers curie content is list ed in Table 12.2-11. The location of the LLRWSF is shown in Figure 1.2-2. (LBDCR 13-009, R307)

(LBDCR 13-010, R307) 12.2.1.11 Original Steam Generator and Reactor Vessel Head Storage Facility

In support of the Waterford 3 (W3) SG/RVCH Repl acement Project, the Original Steam Generator Storage Facility (OSGSF) was added as a part of Steam Generators / Reactor Vessel Head replacement project. The Original Steam Generator Storage Facilit y (OSGSF) is located outside of the Protected Area and within the site Owner Controlled Area. The OS GSF is located well away from any safety-related onsite systems, structures, or co mponents. The OSGSF is designed as a non-safety related structure to be used to provide secure storage until site deco mmissioning of the two Original Steam Generators (OSGs), the Original Reactor Vessel Closure H ead (ORVCH) and Original Control element Drive Mechanisms (OCEDMs) that were removed and replaced during the W3 SG/RVCH Replacement

Outage.

The location of the OSGSF is shown on FSAR Figure 1.2-2.

The movements of the OSGs, ORVCH and OCEDMs into the OSGSF were accomplished through an open side to the building facing Plant North towards Warehouse 5B. The closure of these openings has been accomplished by means of pre-cast concrete panels sealed to the OSGSF walls that minimize airflow through the panel joints.

The design of a reinforced concrete floor account ed for supporting the loads anticipated during facility construction and offloading and storage of the OS Gs, ORVCH and OCEDMs. The floor slab was elevated two (2) feet above finished grade of 16' so that surface water coul d drain away from the building.

The OSGSF floor was coated to create a barrier to prevent leaching of contamination into the floor.

The 24" wall concrete thickness has been established to allow unrestricted personnel access to the

outside of the building in accordance with the NRC unr estricted access criteria found in 10 CFR 20. The OSGSF roof will not be accessed by members of the public, and thus, the 10 CFR 20 dose limit of 100 mR/yr is not applicable to the OSGSF roof.

The OSGSF is designed to provide adequate cl earance between the stored components and wall surfaces to permit personnel to visually inspect these areas if needed.

The perimeter fence is equipped with a lockable gate wh ich is controlled by Radiation protection. The dose rate at the perimeter fence is as depicted on Table 12.3-1. The OSGSF is designed for adequate

flood protection for the OSGs, ORVCH, and OCEDMs. The OSGSF is not designed for occupation except for the capability to perform in spections. Accordingly, the interior of the OSGSF is not required to meet emergency egress requirements or to have insta lled ventilation systems. Similarly for the purpose of long term storage of the OSGs, ORVCH and OCEDMs , which requires no occupancy of the facilities by personnel, the OSGSF is not designed for any water, wastewater, electrical , or telephone services.

The building concrete shielding design meets the radiological requirements of 40 CFR 190, 10 CFR 20 and plant license requirements, and provides adequate shie lding to limit the contact dose rate to 0.1 mR/hour on the exterior wall surface of the building. (LBDCR 13-010, R307)

WSES-FSAR-UNIT-3 12.2-5 Revision 308 (11/14)

(LBDCR 13-010, R307)

The OSGSF roof is equipped with watertight membrane r oofing system to preclude moisture instrusion in the storage facility.

The floor sumps with an external access are provided as common collection point for any liquid within the OSGSF. The sampling port will be used to sample any in ventory that collects within the sump, as well as to remove such inventory without requiring entry into the OSGSF.

Two ground water sampling wells have been added down gradient from the OSGSF to monitor

groundwater impact assuming an unlikely release of c ontaminated water from the OSGSF. Monitoring will be performed to identify and mitigate radiologica l contamination that could reach groundwater. (LBDCR 13-010, R307)

(LBDCR 13-0020, R308) 12.2.1.12 Independent Spent Fuel Storage Installation (ISFSI)

In order to provide adequate spent fuel storage capac ity for WF3, Entergy has established an ISFSI at WF3 on a site located south of the four large water storage tanks that are situat ed at the south end of the WF3 plant area, just west of the switchyard, within the Protected Area. The ISFSI pad is sized to store 72 HI-STORM storage casks, with each cask capable of st oring 32 spent fuel assemblies, which is adequate to meet the projected WF3 spent fuel storage needs over the life of the nuclear power plant.

The WF3 ISFSI operates under the conditions of the general license in accordance with 10 CFR Part 72 regulations. The spent fuel storage cask designs t hat are approved for use under the general license are listed in 10 CFR 72.214. The HI-STORM 100 Cask System has been approved for use, and is listed in 10

CFR 72.214. The design basis for the HI-STORM 100 Cask System is provided in the Final Safety Analysis Report (FSAR) for the HI-STORM 100 Cask System and as supplemented by changes made by

Entergy Operations, lnc., the gener al licensee, from the HI-STORM FSAR under the provisions of 10 CFR 72.48. Amendment No. 5 to the HI-STORM 100 Co C is being used as the licensing basis for the WF3 ISFSI and dry cask storage activities.

ISFSI operations is evaluated under the WF3 ISFS I 10 CFR 72.212 Evaluation Report, which includes the Radiological Evaluation for the ISFSI as required by 10 CFR 72.104. (LBDCR 13-0020, R308)

12.2.2 AIRBORNE RADI OACTIVE MATERIAL SOURCES

Equipment cubicles, corridors, and areas normally occupied by operating personnel can contain small amounts of airborne radioactivity as a result of equipment leakage. For the purpose of evaluating the

potential exposure to personnel from th is activity. This subsection pr esents a description of the sources of activity and the models and parameters used to ev aluate airborne radionuclide levels in the Reactor

Auxiliary Building, the Reactor Building, the Fuel Handling Building and the Turbine Building. Table 12.2-14 includes assumptions, parameters and sources of ai rborne radioactivity used in the analysis. The sources are determined for each area assuming that leak age occurs in that area and that the leaking fluid contains a fraction of the reactor c oolant activity. This fraction is determined from process consideration of leaking fluid (amount of filtering, degassing, demineralization etc. prior to leak). The leak rate is based on typical data from operating plants. The equilibri um airborne concentration is then determined by use of the standard equation of build-up and removal, w here build-up is caused by leakage and removal both by radioactive decay and ventilation.

The isotopic airborne concentrations as a fracti on of maximum permissible concentration in air (10CFR20) were calculated for those areas nor mally occupied by operating personnel and where a potential for high exposure exists. These values are presented in Table 12.2-15 and indicate that the dose to a critical organ of a worker, adjusted on the basis of weekly occupancy, would be well below the

maximum allowable limit. Furthermore, the dose calculated based on these values would be highly conservative because the maximum permissible conc entrations (MPCs) given in 10CFR20 are based on infinite cloud assumptions while volumes of the applicable areas are limited.

WSES-FSAR-UNIT-3 12.2-6 Revision 308 (11/14)

(DRN 99-2362, R11)

A more detailed room by room analysis is performed fo r the Reactor Auxiliary Building. In this case airborne radionuclide concentrations in the form of C/MPC were calculated as well as the whole body dose, in mrem per hour occupancy, resulting from inhalation and external exposure. The inhalation and external whole body dose conversion factors were ta ken from Table E-7 of Regulatory Guide 1.109, for the adult group Calculation of Annual Doses to Man fr om Routine Releases of Reactor Effluents for the purpose of Evaluating Compliance with 10CFR Part 50, Appendix I (Revision 1) and Table D-3 of WASH 1258 (3), respectively. The WASH-1258 values for a semi-infinite cloud model result in highly conservative dose values. The assumptions used in the analysis are ess entially the same as those listed in Table 12.2-14. The differences are that for gas eous releases the iodine partition factor is assigned a valve of 1.0, and 0.05 for liquid leakage associated with the steam generator blow down heat exchanger, tank and pumps. Table 12.2-16 lists the results of the equipment and equipment leakage rates. (DRN 99-2362, R11)

A negligible amount of radioactivity is expected to be released due to removal of reactor vessel head, movement of spent fuel or relief valve venting. T herefore, contribution from these sources to airborne activity are not considered.

WSES-FSAR-UNIT-3 12.2-7 Revision 307 (07/13)

The airborne concentration of a radioisotope in an ar ea having a constant leak rate, source strength and exhaust rate, can be calculated by the equation given bel ow. Radionuclide concentra tions in other areas such as corridors are calculated assuming the air in the corridor can be contaminated by exhaust from nearby areas.

(DRN 02-110, R12)

FSAR Table 12.2-15a and 12.2-16a provide isotopic airborne concentrations as a function of derived air

concentration (DAC) from 10 CFR 20, Appendix B. (DRN 02-110, R12)
