TECHNICAL REPORT               Project No. 29487-NCS0097 SUPPORTING                    ECR No. 09-00301 ENGINEERING CHANGE                         Rev. 0 REQUEST                       Date: 12/03/09 1.3      Evaluation Assumptions 1.3.1 For the purposes of this report, outside walls are not considered requiring a fire rating unless an exterior combustible (i.e., oil filled transformer, etc.) exists, which creates an exposure hazard.
1.3.2 Small quantities of grease (< one pound) or oil (< one quart) used as a lubricant in valves, motors, pans, damper operators and pumps will not be considered as contributing to a fire when contained within packing glands, bearings, or reservoirs.
1.3.3 Electric power and electric equipment such as motor control centers will not contribute significantly to the fire loading due to their metal enclosures. Similarly, totally enclosed electric motors are not considered to contribute significantly to fire loading.
1.3.4 It is assumed that a postulated fire is unlikely to exist if only electrical cables are involved. The construction of the specified electrical power, control, and instrumentation cable meets IEEE 383/UL 1277 which certify the cables non-propagational and fire resistance capabilities.
1.3.5 Electrical faults will be mitigated by selective tripping of breakers or blowing of fuses.
1.3.6 All cables, except festoon cables servicing the bridge crane, are in conduit.
1.4      Definitions 1.4.1 FIRE AREA- An area of a facility that is separated from other areas by complete fire barriers with at least a two hour rating. This includes walls, floors, and ceilings, with any openings therein protected with seals or closures having a fire resistance rating equal to that of the barriers.
1.4.2 FIRE ZONE- the subdivisions of fire areas (as defined above) which are subdivided by fire rated partitions or special separation.

TECHNICAL REPORT              Project No. 29487-NCS0097 SUPPORTING                     ECR No. 09-00301 ENGINEERING CHANGE                        Rev. 0 REQUEST                        Date: 12/03/09 1.4.3 HIGHLY PROTECTED RISK - The term involves the use and application of judgment and thus does not lend itself to a precise, fixed definition applicable, in all locations and situations. It has the same meaning and intent as is commonly understood when this or the term, improved risk, is used in the insurance industry. Generally, a Highly Protected Risk property is one that would qualify for complete insurance coverage by the Factory Mutual System, the Industrial Risk Insurers, and other industrial insurance companies that limit their insurance underwriting to the best protected class of industrial risk. The most evident characteristic of such a property is the existence of reliable, automatic fire extinguishing systems throughout all buildings of combustible construction or content where the building is vital to operational, continuity or may experience a large property loss from fire in the absence of an automatic extinguishing system.
1.4.4 DESIGN BASIS FIRE - A fire that is the most severe accident of this type. In postulating such a fire, failure of automatic and manual fire suppression provisions is assumed except for those safety class items/systems that are specifically designed to remain available (structurally or functionally) through the event.
1.4.5 FIRE HAZARD ANALYSIS - An analysis, documented in report form, which establishes a systematic approach to fire protection design which will ensure that all fire protection requirements are met and will facilitate a fire protection review.
The analysis is documented in report form in the facility project files and referenced by the Safety Analysis Report.
1.4.6 MAXIMUM CREDIBLE FIRE LOSS - The maximum loss that could occur from a combination of events resulting from a single fire. Any installed fire protection systems are assumed to function as designed. Due to the uncertainties of predicting human action, the effect of emergency response is generally omitted except for post-fire actions such as salvage work, shutting down water systems, and restoring production.
1.4.7 MAXIMUM POSSIBLE FIRE LOSS - The maximum possible loss that could occur in a single fire area assuming the failure of both automatic and manual fire extinguishing actions.

TECHNICAL REPORT              Project No. 29487-NCS0097 SUPPORTING                    ECR No. 09-00301 ENGINEERING CHANGE                       Rev. 0 REQUEST                       Date: 12/03/09 The facility is comprised of three major areas including a cell storage area (for storage of dewatered resins and high-level DAW), a warehouse storage area (for storage of Dry Active Waste) and a service area (for material transfer, treatment, and control operations).
A. The Cell Storage area contains 35 concrete storage cells for the storage of dewatered condensate and reactor water cleanup resins and other appropriately packaged materials. The inner cell walls are 1-2 thick while the outer walls of north, south and west perimeter cells are 3 feet thick. Each cell is covered with two overlapping removable concrete cell covers that are approximately 2 feet in thickness. Eighteen (18) cells are approximately 36 feet in depth. The east and west perimeter cells are somewhat larger to allow equal storage capacity due to crane hook coverage limits. Each of these cell will accommodate four (4) 8-120 high integrity containers (HICs) stacked upright to four (4) levels high. The containers are supported by stacking rack grids. Five additional partial cells are located along the south perimeter to allow full crane coverage of the adjacent cells. The partial cells are serviced by an auxiliary hoist of the overhead bridge crane.
B. Dry Active Waste (DAW) Storage Area is located adjacent to the Cell Storage Area and encompasses of 6,000 square feet in an open warehouse configuration. The thickness of the concrete wall adjacent to the cells is 2.5 feet and that of the remaining three walls is 1.5 feet.
Space for storage of approximately 80,750 cubic feet of compacted or non-compactible DAW is available.
C. Service Area adjoins both the Cell Storage Area and DAW Storage Area and included those areas required for the transfer, treatment. Control and accountability of the low-level radioactive waste to be stored in the facility.
: i.      Truck Bays- there are two truck bays (indoor and outdoor) for the receipt and shipment of low level radioactive waste. The indoor truck bay has a drain which leads to the facility sump system so that precipitation runoff from the transport vehicle will be contained for analysis prior to discharge.
ii. Control Room/Records Center - Within the facility main control room are the controls for the bridge crane which is used for the transfer and placement of waste containers, and the closed circuit television system which is used for remote operating capabilities. Also located adjacent to the control room is an area for the storage of radioactive waste storage and shipping records.
This area will also accommodate a data base computer system for Appendix E- 8 of 32

TECHNICAL REPORT               Project No. 29487-NCS0097 SUPPORTING                    ECR No. 09-00301 ENGINEERING CHANGE                        Rev. 0 REQUEST                       Date: 12/03/09 recording waste receipt and shipment information, such as decay calculations, for shipping purposes.
iii. Local Control Room - A shielded local control room is located on the Cell Storage Area operating floor Level to provide line-of-sight viewing of the overhead bridge crane. This is necessary to accomplish such operations as transfer of HICs from stacking containers to shipping casks and movement of large contaminated items.
iv.      Access Control Area - Access to the waste storage areas is controlled by health physics personnel within the access control area. The health physics counting room and instrument room are located here as well as personnel decontamination area, sanitary facilities, and a protective clothing storage and change area.
: v.       Sump/Sump Pump Area - The facility hot sump tank and cold sump (concrete sump) and their associated pumps are located in this area. These sumps collect both the contaminated and non-contaminated liquids produced within the facility via a drain system.
vi.      Dry Active Waste Staging Area - The forklift truck storage area and the fire service valve room are located here. The forklift truck is used for the transfer and stacking of DAW containers within the facility.
vii. WAC Equipment Room - The W A C equipment room contains the air handling units for the Cell Storage Area, DAW Storage Area, Truck Bay, hot sump and DAW Staging Area. The air conditioning equipment serving the main control room/records center and the access control area are also located here.
viii. Electrical Equipment Room - The Electrical Equipment Roam contains the 480 volt switchgear from which the electrical components within the facility are powered. Two 480 volt motor control centers are also located here.
4.2    Important Processes, Equipment, and Cabling Amounts of waste to be moved into the storage area are limited to the size of one transportation vehicle at any given time. Stored waste is expected to be processed waste in the form of dewatered resin. Dewatered resin waste will be contained in high integrity containers (HICs) made of molded high-density polyethylene or poly HICs in metal shells. The HICs contain filtered vents and are corrosion resistant. The standard HIC will Appendix E- 9 of 32

TECHNICAL REPORT                Project No. 29487-NCS0097 SUPPORTING                      ECR No. 09-00301 ENGINEERING CHANGE                         Rev. 0 REQUEST                         Date: 12/03/09 be 8-120, but others containers sizes have been generated and are currently waiting for long-term storage.
Corrosive or reactive wastes are not authorized for LLRWSF storage without first processing to neutralize those conditions which may lead to corrosiveness or reactivity of the material to be stored.
The following paragraph describes the LLRWSF truck unloading/loading process.
A tractor-trailer is moved into the truck bay area. The tractor is disengaged and the truck removed from the facility. The truck bay doors are then closed. The ventilation system is shut down. The trailer's contents are removed by a remote-operated crane and hoisted into the storage area. The LLRWSF cranes are equipped with a winch system which permits them to be manually retracted over the truck bay without electrical power or functioning drive motors. The design of container lifting equipment is such that dropping a container is highly unlikely. Additionally, containers are constructed in accordance with DOT standards and are, therefore, highly resistant to impact damage. Consequently, the probability that a container drop will occur and the contents be released within the truck bay is low, and in any case will not credibly spread beyond the Truck Bay zone.
With the truck removed, significant sources of potential ignition are not available in the truck bay. Additionally, Automatic and Manual Fire Suppression and smoke detectors are provided for the truck bay. Consequently, the probability that any combustible contents will be released or exposed to any source of ignition within the truck bay is low, and with Truck Bay fire suppression systems installed, in any case will not credibly spread beyond the Truck Bay zone.
4.3     Epoxy Coating Data on epoxy utilization, thickness of application, type of epoxy (if used), etc. for the PBAPS LLRWSF were not provided to URS - Washington Division by Exelon.
Therefore, the following discussion and conclusions are based upon the assumed similar LaSalle County Station IRSF epoxy use. However, if available, Exelon confirmatory data searches are suggested. In any case, due to the Peach Bottom facility construction, a source of ignition for a fire in an open cell to initiate a wall or floor epoxy fire in the cell (if at all credible), initiating an epoxy fire that spreads throughout the cell and could potentially with enough time initiate a HDPE HIC fire event without such events being noticed by the operators involved with the operations during the cell being open is considered incredible.

NRC Industry Notice 2007-26 on Combustibility of Epoxy Floor Coatings at Commercial Nuclear Power Plants defines a non-combustible material as:
: a. A material which in the form in which it is used and under the conditions anticipated, will not ignite, burn, support combustion, or release flammable vapors when subjected to fire or heat; and
: b. Material having a structural base of noncombustible material, as defined in a., above, with a surfacing not over 1/8-inch thick that has a flame spread rating not higher than 50 when measured using the test protocol of American Society for Testing and Materials (ASTM) E 84, Standard Test Method for Surface Burning Characteristics of Building Materials.
On July 22, 2009, URS - Washington Division personnel met with Mr. John De Barba, Field Technical Service Manager for PPG Protective & Marine Coatings, the current owner of Keeler & Long, to discuss the flame spread rating of the Keeler & Long epoxy surface finish 4500. Mr. De Barba initially provided test results performed in accordance with ASTM Standard E-84, indicating tested values of 45 for all thicknesses tested up to 25 mils dry film thickness. Mr. De Barba indicated that thicknesses above this level would not be applicable despite the Field Painting Specification, as cracking of the coating takes place above these thicknesses which would render them as unacceptable upon inspection. However, in response to a URS - Washington Division request for additional information regarding flame spread ratings of thicker Keeler & Long epoxy No. 3500, Mr. De Barba provided additional ASTM Standard E-84 test results of a flame spread index of 53.059 for coatings up to 30 mils in dry mil thickness.
Industry Notice 2007-26 indicates that epoxy floor coverings at the Donald C. Cook Nuclear Power Plant with thickness between 0.115 inches (115 mils) and 0.230 inches (230 mils) with flame spread ratings of 140 to 150, and at the Duane Arnold Energy Center with a flame spread rating of 110, were acceptable with respect to not causing fires to propagate. As Exelon IRSF epoxy floor coating thicknesses and flame spread Appendix E- 11 of 32

TECHNICAL REPORT              Project No. 29487-NCS0097 SUPPORTING                    ECR No. 09-00301 ENGINEERING CHANGE                        Rev. 0 REQUEST                        Date: 12/03/09 ratings are both less than one-half those considered acceptable with respect to combustibility at other plants, the Exelon IRSF epoxy floor coating is considered acceptable with respect to not causing fires to propagate.
In conclusion, although testing for up to 30 mils dry film thickness of KL3500 resulted in Flame Spread Rating slightly above 50, the epoxy coating is considered non-combustible based on:
x   Epoxy dry film thicknesses sufficient to result in flame spread ratings above 50 would be subject to cracking upon application, and therefore actual thicknesses would have flame spread ratings below 50.
x   Industry Notice 2007-26 actual plant data indicates non-combustibility of epoxies at much greater thicknesses and higher flame spread ratings.
4.4     Fire Protection Systems The Fire Protection System is designed in accordance with appropriate National Fire Protection Association, standards and with ANI (American Nuclear Insurers) recommendations. This system provides fire detection, audible and visual alarms, and fire extinguishing systems incorporating both automatic and manual features. Upon fire suppression system actuation, fixed fire extinguishing systems will automatically actuate in certain areas of the facility. Concurrently, audible and visual alarms will be activated locally, in the facility control room and in the main plant control room. In addition, a variety of manually operable fire extinguishing equipment will be available for manual control and extinguishing fires involving various classes of hazard.
4.4.1   Water Supply System - The water supply system consists of a new connection to the existing 8-inch fire main located at the North Warehouse. The existing fire main provides adequate water volume and pressure to meet the fire protection needs of the facility. An 8-inch flanged connection with a post indicator valve is used in the tie-in at the northwest corner of the North Warehouse. The underground supply main consists of an 8-inch cement-lined cast iron, pipe with cement-lined cast iron fittings.
A11 fittings are restrained and anchored in accordance with National Fire Protection Association (NFPA) Standard - NFPA 24.
4.4.2   Sprinkler System - Wet pipe sprinkler systems are provided for the protection of areas where combustibles will be stored or may accumulate including the facility control room/records storage area, the access control area, the Truck Bay, the DAM Staging Area, and the DAW Storage Area.
Appendix E- 12 of 32

TECHNICAL REPORT               Project No. 29487-NCS0097 SUPPORTING                    ECR No. 09-00301 ENGINEERING CHANGE                        Rev. 0 REQUEST                       Date: 12/03/09 The sprinkler system design meets the requirements of NFPA 13, "Installation of Sprinkler Systems," for Ordinary Hazard Groups II and III.
Those areas where combustibles may accumulate and which are normally unoccupied are designated as Group II (DAM Storage Area). DAW is considered a Class A combustible material. Those areas where combustibles may accumulate and which are normally occupied are designated as Group III (control room/records storage area, access control area, Truck Bay, DAW Staging Area).
Sprinkler system actuation is accomplished by the melting of a fusible link on the sprinkler from the heat generated by a fire, releasing water only from those sprinklers which have opened. Water Flow in any sprinkler system feed main will cause actuation of the zone water flow detector switch, activating local and remote fire alarms, and signaling the existence of a fire condition at the annunciator panel. The sprinkler system isolation valve is supervised by either a position switch or operating controlled lock.
4.4.3 Standpipe and Hose Stations, Hydrant with Hose Cart House - The facility hose stations are provided for manual control and extinguishing of fires by facility personnel. They are designed and located in accordance with NFPA 14, "Installation of Standpipe and Hose Stations," to provide coverage for all areas of the facility. The design water flow and duration is 100 gpm for 30 minutes. Valves are provided for isolation of the standpipe and its risers from the facility fire protection supply system, and are supervised in the same manner as the sprinkler system isolation valve.
Each hose station is equipped with a 1-1/2 inch pressure restricting angle valve, a 100' length of 1-1/2 inch neoprene-lined collapsible fire hose, a swinging hose reel, a 2-1/2 gallon pressurized water fire extinguisher and a spanner wrench.
One 6-inch fire hydrant is provided for facility and/or fire department personnel. It is equipped with American National Fire Hose connection screw threads to be compatible with fire department hose fittings. A curb box operated valve is provided in the hydrant supply line to allow for isolation of the hydrant for repair.
A hose cart house is provided at the hydrant location for storage of firefighting equipment. It contains a hose cart, approximately 600 feet of 2-1/2 inch fire hose, approximately 400 feet of 1-1/2 inch fire hose and an equipment box containing items necessary to maintain reliable operation of the fire hose and hydrant systems. The fire hydrant and hose cart hose are located and installed in accordance with NFPA 24, "Outside Protection."

4.4.5   Alarms and Annunciators - In addition to the sprinkler system and its associated control initiated alarms and annunciations, there are manual pull box-type fire alarms on each floor of the facility and local and remote alarm bells. Flashing red alarm lights and buzzer units are provided to give audible and visual signals at both the facility control room and the main plant control room. The system is designed in accordance with NFPA 72D, "Proprietary Protective Signaling Systems.
Located in the facility control room, the fire annunciator panel monitors the power supply and provides all control and supervisory functions required for the sprinkler, standpipe and hose, manual fire alarm, low temperature detection, and in-duct smoke detection systems.
Fire conditions in the storage facility are divided into the following zones:
Zone 1 - Service Head Area Zone 2 - Truck Bay and DAW Staging Area Zone 3 - DAM Storage Area Zone 4 - Cell Storage Area, local control room, and fan room These conditions will appear on the facility fire annunciators panel and in the main plant control room as separate indications for each zone. Any fire condition received activates all facility fire alarm bells simultaneously.
A common trouble signal will be transmitted to the main plant control room from the facility annunciator panel for any trouble condition. The annunciator panel is provided with a battery backup should normal 120-volt AC power be interrupted.
Also, low temperature detectors are located in those areas of the storage facility in which water filled piping is installed and which are most susceptible to freeze conditions. The detectors are set to alarm at a temperature of 38o F (Normal facility temperature is maintained at a minimum of 40o F), utilizing normally closed contacts. These detectors provide trouble input to the facility fire annunciator panel, and are displayed as a single low temperature indication.
4.4.6   Operational Hazards - The application of water on fires in the vicinity of high voltage electrical equipment could constitute a life hazard to personnel due to the electrical conductivity of water. Adjustable pattern spray nozzles are installed with the hose stations. These adjustable water Appendix E- 14 of 32

This analysis focused on the areas involving Class B/C waste.
5.2    Ignition Sources Ignition sources in the LLRWSF storage bay are relatively limited. NFPA reported that 29% of fires initiates by an electrical ignition source and 34% by open flames. . In the LLRWSF, there is no human accessibility in the storage bay; therefore the only credible ignition source is failure of the crane cable and direct contact with the combustible material. As calculated in IRSF Storage Bay Fire HIC Spacing Assessment L-003429, Rev 000, such direct contact would be required for a period of 1,386 seconds to result in ignition.
In addition, Peach Bottom created procedures to minimize the risk of fire in the LLRWSF building such as loading/unloading containers, periodic surveillance, fire detectors and automatic suppression at some classifies Class III areas.

Exelon loading and unloading procedures are followed to minimize fire potential risks. See Section 4.2 for loading/unloading procedure description. In case of an incredible fire in the truck bay, manual and automatic suppression, and the Peach Bottom fire brigade are available for immediate remediation.
Only during this transient loading/unloading event there is a possible fire risk, which would be controlled.

11.0 DESIGN BASIS FIRE DESCRIPTION Fire in a closed (covered) cell and fire initiation on a temporarily open cell are considered incredible.
The probability of having a source of ignition in the storage area is remote. The storage bay is lighted and during the transient process where an unique cell cover is off, operators are constantly monitoring the area. The possibility of a cable igniting (e.g., from a short circuit) and being in direct contact for the sufficient time required to ignite a HIC is unrealistic. Adjacent cells are maintained closed until cell is loaded/unloaded; this closure ensures no postulated ignition source could enter a cell, and also ensures insufficient oxygen would be available to sustain a postulated fire. Two manual hose stations are available at the top of cell for manual extinguishing of a fire event, see Attachment 6.4 - Fire Protection Equipment Location Sketch. In addition, the Peach Bottom Fire Brigade will respond to a fire in this area. Consequently, there is no credible fire scenario in the Storage Cell.
12.0 CONSEQUENCES OF DESIGN BASIS FIRE A postulated fire would be extinguished by manual suppression by the PB Fire Brigade. Any drainage will be collected in the cold/hot sump system until the sump reaches its maximum capacity and the cell drain lines begin to back up the flow. No fire spreading will occur in the adjacent cells since reinforced concrete will contain such an incredible fire for days.
Due to the availability of the fire suppression system and the wet nature of the stored resin, no resin burning resulting in radioactivity release is postulated.

In the event such an incredible fire occurs during a loading/unloading procedure when the cell is opened, personnel would be available and be able to see the fires initiation, and manual fire hoses and the fire brigade are adequate to prevent the fire from spreading within the LLRWSF storage area.

: 1. Introduction & Purpose The purpose of this calculation is to re-analyze the design basis event of Container Drop during waste handling for the Peach Bottom Low Level Radwaste Storage Facility (LLRWSF) for currently expected design basis source terms, including for radwaste received from the Limerick Station. This analysis is to demonstrate that the dose consequences of this bounding event do not exceed a small fraction (10 percent) of 10 CFR Part 100 dose limits, as per Reference (7), the General Information section of Generic Letter 81-38 entitled Storage of Low-Level Radioactive Wastes at Power Reactor Sites, and as suggested in the EPRI Guide (Reference (3)).

Assumptions 3.1 Technically Justified Assumptions 3.1.1 Analyses are for an actual resin isotopic mix from Limerick, based on a nominal 250 R/hr container to permit off-site shipment, and a Peach Bottom isotopic mix from Rev. 0 of this calculation (attached) adjusted to a nominal 400 R/hr container.
3.1.2 The crane in the LLRWSF can only carry one container at a time and therefore one container will be assumed to drop into an area below, permitting a relatively ready release for the drop accident.
3.1.3 A denser material will yield a high radioactivity content for a given contact dose. A lower density will yield a higher release fraction upon HIC failure from impact.
3.2 Assumptions that Require Verification There are no assumptions that require verification in this calculation.

: 5. Method of Analysis In general, these analyses determine or utilize:
(1) a bounding design basis container content; (2) fraction of contained activity released for airborne dispersion, from Ref. 6 (attached);
(3) appropriate dispersion factors; (4) resulting doses at the Exclusion Area Boundary (the bounding location for the assumed instantaneous ground level release) 5.1 Design Basis Container Activity The Chem-Nuclear system polyethylene HIC has an inner diameter of 60 inches and a fill line height of 72 inches. The HICs contents will have a bounding isotopic mixture from either Limerick or Peach Bottom. The Limerick HIC contents will have decayed for a period of 60 days and are at a contact dose rate of 250 rem/hr for Limerick waste, and 400 rem/hr for bounding Peach Bottom waste.
5.2 Internal Events 5.2.1   Container Drop In this accident, one container will be moved from the LLRWSF Storage Area, over the Local Control Room and then dropped at the North end of the building. This accident is illustrated in Figure 5.2-1. It is shown here that the container will free fall from a height of 170-9 and fall to an elevation 118. Upon impact the container will rupture and a fraction of resin will be released to the surrounding area.

: 6. Numeric Analysis 6.1 Bounding Design Basis Container Contents Bounding HICs generated at Peach Bottom are assumed to have a contact dose rate of 400 R/hr. A container with this contact dose rate may require a hold in storage for a decay period. Containers shipped from Limerick are assumed to have a maximum contact dose rate 250 R/hr, because of limitations on dose rates exterior to a transport package.
Shielding analyses have been performed on an all Co-60 basis to simulate worst case conditions. However, a design basis event involving postulated airborne releases and inhalation doses must consider relative inhalation dose conversion factors. For this reason, isotopic mixes for the bounding resin sources were evaluated using the following process.
: 1. For Limerick, RWCU phase separator characteristics from UFSAR Table 11.4-8 Expected Radionuclide Inventories of Solid Waste Management System Components were used. For Peach Bottom, Table 1 from Reference (6)
Design Basis RWCU Resin was used.
: 2. These 2 mixes were each placed in a nominal HIC to determine a contact dose rate, using MicroShield. For Limerick, a decay before container loading period of 60 days was assumed, and the resulting mix of isotopes adjusted using MicroShield to result in the 250 R/hr contact dose container for Limerick and the 400 R/hr contact dose for Peach Bottom.
: 3. These isotopic mix concentrations were then multiplied by effective inhalation dose conversion factors from FGR-11 (Reference 5) and then summed to

CALCULATION No L-003430                     REV. 001                       PAGE 8 determine which mix would yield the maximum inhalation dose. The result of this step was that Peach Bottom had the bounding isotopic mix.
: 4. With the bounding isotopic mix in a container, the contents were adjusted proportionally to yield the design basis 400 R/hr Peach Bottom Container, which based on both isotopics and contact dose rate limits, is bounding.
: 5. Accidents are evaluated based on multiplying the following factors: (1) Container Contents; (2) the number of containers affected; (3) the release fraction applicable to the event, from Reference 6; (4) the Peach Bottom EAB X/Q for ground level releases, from Reference 6; (5) a Breathing Rate of 3.47E-4 m3/s, from Reference 6; and (6) Dose Conversion Factors from Reference (5).
: 7. Results This calculation was performed to evaluate the Peach Bottom LLRWSF internal design basis event of a container drop as a bounding event. The methodology is conservative as discussed below. The calculated doses are:
Event                     Calculated Dose                      Limit Container Drop                            0.736 rem                       2.5 rem Some of the conservatisms applied in this calculation are listed below.
i Containers are assumed to have a contact dose rate of 400 R/hr, which is the maximum anticipated in the LLRWSF.
i As historically used, Release Fractions for container drop use a conservative NUREG-1320 based dry powder spill scenario to determine an airborne fraction.
The worst case Powdex-like resin is expected to be wet and to be less easily made airborne. Larger bead resin would be even less likely to become airborne. The assumed drop is from the maximum release height with a resulting calculated airborne release fraction of 0.0294, which is rounded to 0.03.
i All airborne activity is assumed to be instantly released to the environment from the LLRWSF. No particle settling is assumed either in the LLRWSF or in transit to the EAB.
: 8. Conclusion By performing this evaluation, it has been concluded that a container drop of a Peach Bottom HIC is a bounding event. The level of conservatism includes significant safety factors for calculating an effective dose release to the EAB through a container drop.
Doses from the bounding internal events in the LLRWSF are within 10% of 10 CFR 100 limits.

The container is assumed to hold the maximum amount of activity observed, over the last five years, in an RWCU resin liner. The container is assumed to drop from the maximum crane lift height to the floor in an empty storage cell.
A very conservative set of assumptions is used to establish the amount of activity which becomes airborne and leaves the LLRWSF. Accident meteorological assumptions are those previously established for PBAPS design basis accidents.
The purpose of this calculation is to provide assurance that calculated doses from this accident are well within 10 CFR 100 limits at the Exclusion Area Boundary. Since this accident is modeled as a puff release, doses at the LPZ would be significantly lower.
Utilization of this calculation by persons without access to the pertinent factors and without proper regard for its purpose could lead to erroneous conclusions. Should it become desirable to use this calculation to support design or station activities other than those explicitly specified in this section, the responsible engineering branch (as noted in block 4 of the cover sheet) shall be contacted to ensure that the purposes, assumptions, judgments, and limitations are thoroughly understood.

This mix is a composite of two historical containers. The first container's contents are from the worst case container handled over the last 5 years, for whole body dose purposes. 1-131 content was taken from the worst case container for thyroid dose purposes.
The methodology for airborne release is based on guidance from NUREG-1320 (Ref. 2) for unconfined powder spills. NUREG-1320 provides algorithms based on empirical data.
Airborne material from powder spills occurs because of shear forces as the material falls, and on rebound as the material hits the floor. In the dropped container case, no shear contributions would be expected since the material remains in the container during the fall.
Additionally, the dewatered resin is of a consistency of wet sand, so a dry powder assumption is considered conservative for rebound purposes. Also the ruptured container is still likely to limit particulate rebound to a significant extent. No credit is taken for this phenomenon.
The airborne activity is conservatively assumed to be instantly mixed in the LLRW free air space above the storage area; and to be instantly released. This analysis is done without taking any credit for (1) gravitational settling before exhaust from the LLRWSF; (2) building ventilation system shutoff; and (3) plateout which would be expected as some fraction of the material comes in contact with available surfaces.
The safety related UE&C computer code SPECISO (Ref. 3) is used to convert isotopic data into the source terms in units of Mev/dis.Ci.
Data from PECO (Ref. 4) for X/Q is used to generate the X/Q at the distance from the LLRWSF to the EAB (see attachment A-2). The dose conversion factors for calculating the inhalation total body dose are taken from Reg Guide 1.109 (Ref. 5).

Fraction airborne = 1 x 10-8     X H21 Pp        (Ref.2, page 4.71)
Where        H  = Spill height, cm Pp = Powder density g/cm 3 H      = 170'-9" - (118) - (6) = 46'-9" = 1424.94 cm Where 170'-9" is the elevation of the hook, 118' is floor elevation and 6' is a nominal length of the liner. Hook and floor elevations are taken from Ref. 6.
Since Ref. 1 does not provide resin density for this particular shipment, this density is determined by taking the average of 5 other waste shipments, See Table 2. The resulting density is:
Pp = 0.69 g/cc Therefore, fraction airborne = lxlO- 8 x (1424.94)2 1(6.9E-Ol) = 0.0294 TABLE 3 shows the total Ci. released from dropped liner.

D,: = 0.25 E-" X (Ref. 7 , page 1.3-2)
Where D,,' = gamma dose rate from an infinite cloud (rem/sec)
E"y = average gamma energy per disintegration (Mev/dis)
X       =   concentration of gamma emitting isotope in the cloud(curie/m3)
This equation can be written as:
D y = 0.25 x X/Q x Ei (E-"i XCi)
Where D" = gamma dose from an infinite cloud (rem)
E"yi = average gamma energy per disintegration per isotope i Ci = curie released of isotope i of the liner X/Q = atmospheric dispersion parameter used for the determination of the ground-level concentration ( sec/m 3 ). See derivation below under" Accident X/Q Value".
Computer code SPECISO is used to generate the average gamma energy per disintegration.
TABLE 4 shows the use of SPECISO output to generate E-"i for each isotope. Also TABLE 5 shows the result.

Dt'Y = X/Q x B x E(C j x    DFJ    (from Ref. 5 [Reg. Guide 1.109])
Where Dt'Y = total body inhalation dose (rem)
B     = breathing rates 3.47E-04 m3/sec for time interval between 0 - 8 hrs (from Reference 7).
X/Q = atmospheric dispersion parameter (from Ref. 4) used for the determination of the ground-level concentration ( sec/m3 ). See derivation below under" Accident X/Q Value".
C j = quantity of isotope i released during the accident (curies)
DF j = total body dose conversion factor for isotope i (rem/Ci)
(from Reg Guide 1.109)
TABLE 6 shows the internal whole body dose.
THYROID DOSE The thyroid dose can be calculated using the above formula, substituting thyroid dose factors for DFi .
Total iodine releases are taken based on the highest value observed over the last 5 years in any RWCU resin liner at PBAPS (See Attachment A-I).
Table 6 shows the thyroid dose from iodines. This dose is then combined with thyroid dose contributions that are part of the whole body dose.
The total thyroid dose is 0.215 rem, which is well below the 300 rem dose limit of 10 CFR 100.

(This attachment is Ref. 4.) Then the two-hour accident X/Q values are plotted as a function of distance to allow interpolation for the distance of 442 meters(
distance from the LLRW to the EAB).
Distance from the LLRW to the EAB The Exclusion Area Boundary per FSAR Figure 2.2.5 is 2700 Ft. from center of each reactor building. The distance from the center of the unit 3 reactor building to the center of the LLRW is 1250 Ft.
Therefore, the distance from the LLRW to the EAB is estimated to be 1450 Ft. or 442 meters.
Figure 1. shows the two -hour accident X/Q as a function of distance. According to this plot the X/Q value for the distance of 442 meters is 9.2E-04 sec/ m3 .

PROJECT    Low Level Radwaste Storage Facility SHEET     let   OF   5.3              DATE        DATE SUBJECT    Container Drop Accident Analysis                J.O. 7112.287 COMPUTER SPREADSHEET VERIFICATION In this calculation a QUATRO-PRO spreadsheet is used to evaluate whole body dose.
Therefore, a method of hand calculation is used to verify the QUATRO-PRO spreadsheet.
1- External Whole Body Doses:
A- Cr-51 From TABLE 4 total released for Cr-5l is 1.25E-Ol Ci and mev/dis is 3.25E-02.
Therefore, the external whole body dose for Cr-5l is = 0.25 . X/Q . E--y . C
         = 0.25x (9.2E-04) x (3.25E-02) x (1.25E-Ol) = 9.34E-07 rem, with QUATRO-PRO the number is 9.34E-07 rem.
B- Co-60 From TABLE 4 total released for Co-60 is 4.44 Ci and mev/dis is 2.50.
Therefore, the external whole body dose for Co-60 is =0.25 . X/Q . E--y . C
         = 0.25x (9.2E-04) x (2.50) x (4.44) = 2.55E-03 rem, with QUATRO-PRO the number is 2.56E-03 rem.
2- Internal Whole Body Doses:
A- Cs-137 From TABLE 2 total released for Cs-137 is 2.07 Ci and from TABLE 5 dose factor for Cs-137 is 5.35E-05 mrem/pCi.
Therefore, the internal whole body dose for Cs-137 is = X/Q . B . C . DF
        =(9.2E-04)x (3.47E-04)x (2.07)x (5.35E-05)x (lE+09) = 3.535E-02 rem, with QUATRO-PRO the number is 3.539E-02 rem.
B- H-3 From TABLE 2 total released for H-3 is 8.45E-05 Ci and from TABLE 5 dose factor for H-3 is 1.58E-07 mrem/pCi.
Therefore, the internal whole body dose for H-3 is = X/Q . B . C . DF
        =(9.2E-04)x (3.47E-04)x (8.45E-05)x (1.58E-07)x (1E+09) = 4.262E-09 rem, with QUATRO-PRO the number is 4.260E-09 rem.

==Dear AI:==

As per your recent telephone request, we have computed accident X/Q values out to 50 miles for the Peach Bottom reactor vents and off-gas stack.          These calculations have been made according to the guidelines of Regulatory Guide 1.145, using the 8/67 through 7/71 meteorological data base.
These calculatiol\s were previously sent by telecopier to yourself and to D. A. Klein of Bechtel on December 13 and 14, 1979.
Vent X/Q The vent X/Q values were computed assuming a ground-level release, using winds from the 75-ft. level of Tower 2, uncor-rected for source elevation. The resul ts of these calcula-tions for the various time periods following an accident are shown in Figure 1. The maximum values occurred in the SE sector at each distance.
The two-hour accident X/Q values are plotted as a function of distance in Figure 2. As you can see, the plot is fairly smooth, and any interpolation between the receptor points given in Figure 1 should produce a negligible error.
Off-Gas Stack X/Q The off-gas stack X/Q values for the various time periods following an accident are shown in Figure 3.                  It should be noted that in the interest of time, these calculations have J     been made in a very conservative manner, assuming the highest terrain of all 16 sectors for each receptor distance.
As per Regulatory Guide 1.145, stack fumigation has been / '
assumed to occur for the first one-half hour of the accident.
Gu ide 1.145 is primarily des igned for EAB and LPZ evalua-tions, and gives no guidance on how far downwind fumigation should be assumed to occur.        After consultation with Joe Levine of the NRC Hydro-Meteorological Branch, we decided to correct only those receptors within 1 mile for stack fumiga-tion.

Mr. Alan Marie December 18, 1979 Page 2 Due to both the meteorology and terrain, the maximum two-hour X/Q at each receptor distance did not always occur in the same sector. At close-in receptors (less than 4,600 m) the
"_ ~ two-hour X/Q values were caused by the very unstable
  ~urs. The very unstable case occurs predominantly with ESE and SE winds, putting the maximum values at the close-in distances in the WNW and NW sectors.             At the farther dis-tances, as the terrain becomes higher, the .5% two-hour X/Q values are caused by the stable case and occur in the NE and ENE sectors. Therefore, the X/Q's in Figure 3 are the maximum sector values at each receptor distance.
A plot of the maximum two-hour X/Q versus distance from the off-gas stack is shown in Figure 4. Due to both the fumiga-tion and terrain corrections, the plot is quite "bumpy" with several peaks. It is for this reason that we did not use a uniform receptor spacing in Figure 3, and instead chose the appropriate distances such that no peaks would be missed if one were to interpolate X/Q values between the receptor dis-tances.
As I have stated earlier, the off-gas stack calculations were done very conservatively for the sake of time.                    If the re-sulting isodose curves are too high, we could produce a less conservative set of X/Q's if given more time. However, until we actually do it, I cannot make an estimate on how much lower the numbers would be.
Sincerely yours,
                                          *.B,t     Jk~_.-

Analysis

== Description:==
Spreadsheets were used to execute arithmetic manipulations of numbers, for various applications within the attachments of this analysis. As a first step, it was verified that the spreadsheets duplicated the calculated values. All of the inputs were checked for consistency with their source and their use, and all results were checked for consistency with expected values. Spreadsheet formula pages are included with the calculations.
The attached computer output has been reviewed, the input data checked, And the results approved for release. Input criteria for this analysis were established.
