1. Purpose The Peach Bottom Atomic Power Station (PBAPS) Low-Level Radioactive Waste Storage Facility (LLRWSF) is an existing facility for the storage of radioactive waste that is either being staged for shipment for disposal, or for waste storage if a disposal site is not available. The LLRWSF can also be used for decay in storage before shipment. Shielding analyses were performed as part of the original design and again in the early 1990’s (See References 1, 2, and 3). In general, those analyses were for drum storage filling the storage cells, with source terms considered appropriate at that time. These historical analyses, and the resulting design are conservative and yielded capabilities and storage flexibility that can address a wide variety of waste source configurations and radioactivity levels. However, the LLRWSF mission, as reanalyzed in this calculation, is specifically for the storage of Class B & C resin in Energy Solutions 8-120 High Integrity Containers (HICs). This may be required for an extended period of time due to disposal site unavailability. These types of waste, on average, may also contain more radioactivity that assumed in original design analyses. Shielding analyses in this calculation are designed to conservatively encompass not only PBAPS waste but also for the possibility that waste could be transported from the Limerick Generating Station (LGS) for storage in the LLRWSF. Analyses are based on container contact dose rates. This will be the primary operational parameter used to assure that waste will be stored such that offsite and onsite dose rate limits are met, and that the ALARA principle is followed.

2. Inputs

1. Based on recent operating experience, a bounding container from PBAPS is expected to be dewatered resin with a contact dose rate of 400 R/hr. This provides for some allowance for the use of a decay in storage period prior to transport to offsite locations. Bounding containers from LGS are to be treated as dewatered resin with a contact dose rate of 250 R/hr, which is considered a reasonable upper bound of immediately shippable waste with a high Co-60 content. Since PBAPS waste is bounding, all stored waste is analyzed as having a contact dose rate of 400 R/hr for central cells. Dose rates for peripheral cells are to be determined based on wall shielding evaluations.

2. Concrete shielding density is 140 lb/ft3, conservative and consistent with existing shielding calculations.

3. Dose rates to offsite receptors are controlled by 40CFR190 and limited to 1 mrem/year. This is a small fraction of the 40CFR190 limit for all nuclear fuel cycle activities of 25 mrem/year.

4. Dose rates in areas outside of, but in the immediate vicinity of the LLRWSF, will be limited to less than 1 mrem/hour, to assure that occupation doses in the LLRWSF vicinity will be within 10CFR20 limits and ALARA. This is an increase from the 0.25 mrem/hr criterion used in original design analyses, but consistent with values used at other Exelon nuclear power stations.


3. Assumptions

3.1 Verified Assumptions

1. Based on the fact that Co-60 can frequently dominate waste contact doses, and because it is the most conservative expected isotope for shielding purposes, a Co-60 only assumption is used. For shielding purposes, this is more conservative that isotopic mixes historically used in LLRWSF shielding analyses (See Attachment A).

2. Storage Cell configuration and dimensions are taken from Reference 4. 3. Waste container are simplified as simply waste in a 5 foot diameter cylinder filled to a 6 foot

height, with a specific gravity of 0.9, with radioactivity levels set to yield the identified contact dose limit. This same configuration and waste strength is then used in shielding analysis.

4. Waste cells, when filled; contain 4 layers of 4 containers each. Based on data collected and discussions with operators, the bottom of waste packages are set at 22.0, 124.5, 227.0, and 329.5 inches above the floor, which is treated as 36 feet below the bottom of cell shield plugs. Each container is centered in its quadrant of the cell. No credit is taken for any shielding effect of the tables that support these packages.

5. Waste cells are modeled based on a nominal 400 R/hr contact container. The central 15 cells are explicitly modeled in this calculation. As a reasonable approximation, Skyshine doses are considered proportional to the average contact dose rate of upwardly exposed containers, the number of such containers, and, effectively, the number of cells in use.

6. Based principally on the assumption 5, 15 full (16) container waste cells on the periphery, and the 5 half cells (south end) are approximated proportionately in terms Skyshine effects to the central cells’ results. This assumption is based on experience with these types of analyses.

7. Assumptions 5 and 6 are considered extremely conservative with respect to possible filling strategies for the LLRWSF, for the following reasons:

a. All containers will not be worst case; and b. Only about 4 containers per year would be anticipated to require long term storage if

Class B and C waste cannot be shipped for disposal. This results in substantial decay as waste accumulates.

Nonetheless, this assumption is used since dose criteria are met even in this extreme.

3.2 Unverified Assumptions None.

5. Identification of Computer Programs The following computer programs are used in this calculation, along with spreadsheets. The programs below are qualified for safety-related use under the URS-Washington Division QA procedures.

1. MicroShield: A computer program used for evaluation of some simple geometry problems. This program uses point-kernel methodology as does the QAD-CGGP computer program used in Reference 1.

2. MCNP: A computer program used for complex geometry calculations including Skyshine analyses. This program uses Monte Carlo methodology as does the MORSE-CGA program used in Reference 2

These newer programs use a simpler and more sophisticated handling of input that, particularly in the MCNP case, facilitates more detailed input. Methodologies are effectively the same as previously used in LLRWSF shielding analyses.

6. Method of Analysis The shielding analyses in this calculation are based on management of LLRWSF loading principally based on observed container contact dose rates. The steps in these analyses are as follows:

A. An individual container MicroShield model is developed, along with selection of isotopic assumptions. Individual container MCNP models are developed to determine the source strength needed for a given contact dose rate.

B. An individual cell is modeled, with one, two, three, and four high stacking of filled layers. This model provides the basis for calculating dose rates immediately above the cell, and also creates a “surface source” from a cell that is used in the overall building Skyshine analysis.

C. A building model is prepared that models the 35 cells, with the central 15 having the “surface source” developed in step B.

D. A wall model is developed reflecting a filled cell to determine contact dose rate limitation for containers in the outside cells.

E. A spreadsheet is developed to turn the result discussed above into actual dose rate calculations. This is because the MCNP models are run on a dose rate per photon/second basis.

F. The dose results for shielding from historically analyzed transient conditions are adjusted based on new source terms and container geometries.

G. The above analyses are used to establish limitations on contact dose rates for containers placed in central and peripheral cells.

H. The above analyses also provide bases for assuring that dose rates limits outside of the building are met, and possibly a basis for Skyshine prediction that could supplement and support predictions based on exterior Thermoluminescent Dosimeters (TLDs).

7. Numerical Analysis

7.1 Isotopic Analysis Attachment A contains a MicroShield based justification for the use of an all-Co-60 based source term for shielding, rather than the historically used mix from Reference 1 and 2. This assumption is conservative, but not inordinately so.


7.2 VISED Geometry and MCNP Model Testing VISED is a visual editor for MCNP that provides visual images of model geometries, and also allows particle test illustrating source locations and scatter events. Attachment B contains these images and are discussed below with respect to individual models.

7.3 HIC Baseline Model Attachment C contains an MCNP run for modeling contact dose rates for a single HIC with a homogeneous waste source 6 feet high and 5 feet in diameter. Page 1 of Attachment B, top figure, shows the geometry. Surface crossing detectors are used at 1 inch (nominal contact) and 1 meter from the waste source. The horizontal lines segment the surface axially to allow the assessment of axial variation and to assure that peaking is considered. Surface crossing detectors can be thought of as tallying particles crossing the surface (angle corrected), dividing by the surface area to determine a fluence, and then applying a fluence to dose conversion factor as a function of photon energy. The net result is a rem/hr per photon/sec value. All MCNP analyses are run on a single photon per second source basis. This run is used to establish the amount of activity (photons/sec) necessary to yield a 400 R/hr contact container. This derivation is shown in the Spreadsheet in Attachment G.

7.4 Skyshine Analysis Basic Cell Geometry The modeling of the LLRWSF is a classical “deep penetration” problem, both because of the 2 foot thick concrete shield overlying the storage cells, and the thickness of air through which the Skyshine analysis is being performed. Therefore, for variance reduction, this analysis is performed in two steps. The first step is to model an individual interior cell. MCNP runs are made for 1, 2, 3, and 4 layer stacking and included in Attachment D. For operational information, doses are also calculated at 1 inch above the cell cover. Page 1 of Attachment B, bottom figure, shows the geometry. Page 2 of Attachment B, top figure demonstrates that source particles, in fact, originate in the containers. Page 2 of Attachment B, bottom figure, demonstrates that behavior of the photon population being scattered by walls, and being transported through the cell cover. Additionally, a surface source is written to a file that collects data of particles exiting through top of the cell in terms of particle weight, direction, and energy. Lateral surfaces of the cell are one half of the wall thickness, and mirrored to simulate the effect of an infinite array for purpose of the cell being modeled. This surface source is used in the actual Skyshine analysis. Basic Skyshine Geometry The LLRWSF is simplified as shown in Page 3 of Attachment B, top figure. The DAW, adjacent compartment and the truck bay are conservatively ignored to maximize dose rates in the immediate vicinity of the LLRWSF. Page 3 of Attachment B, bottom figure demonstrates that the surface source generated in the cell model is properly translated over the 15 interior cells. The walls and roof above the cell are consistent with the design of these bodies, as previously analyzed. Page 4 of Attachment B, top figure shows the Skyshine model geometry. In essence, spherical surfaces are place concentrically around the waste center (also the modeled building center). Two types of surface crossing detectors are used. The first is based on photons crossing the ground surface, which is segmented by the concentric spheres. The detector distance is taken as nominally at


the midpoint distance between adjacent spheres. The second surface crossing detector is the surface of the spheres themselves, from the ground up to the waste height. The MCNP run for Skyshine assessment is in Attachment E, addressing the central 15 cells. This derivation of doses as a function of distance is shown in the Spreadsheet in Attachment G. Variance Reduction MCNP is a Monte Carlo analysis tool, and variance reduction techniques must be used to obtain acceptable statistics for complex geometries such as modeled in this analysis.

The first technique used is importance biasing through the shield cap cell atop the storage vaults. This shield has three inch segments, and importances such that particle splitting is applied to maintain the photon population through the shield.

Importances are also used in the Skyshine model to maintain photon population as a function of distance.

A source translation is also performed to write a surface source above a storage vault, which is then replicated above other vaults, and then re-run for Skyshine analysis.

Dose Conversion Factor Dose conversion factors are taken from ANSI/ANS-6.1.1 (1977) (Table H.2 of the MCNP Manual)

7.5 Wall Shielding Assessment Attachment F, shows the wall shielding model used to determine a limit on container contact such that a 1 mrem/hr dose rate would not be exceeded. Geometrically, this model uses the same arrangement of containers as the Skyshine analyses, but models a periphery cell, where the waste is somewhat further from the outside surface due to crane travel limitations. Here, the outside wall is segmented for variance reduction importance utilization. Attachment F contains the MCNP run for the wall shielding assessment. The Attachment G spreadsheet show the derivation of contact dose limits to assure that contact dose rates outside of the LLRWSF are less than or equal to 1 mrem/hr. The Skyshine contribution in the immediate vicinity of the IRSF is calculated to be negligible.

7.6 Intermittent Dose Considerations Reference 3 evaluated and provided the following results for various intermittent and upset conditions for the LLRWSF.


Because of the new all Co-60 assumption and the increase in contact dose rate these results should be multiplied by 4.5 (an extremely conservative factor given only an approximate increase in contact dose rate of a factor of 2) to increase the source term effects as detailed in Attachment A. These adjusted results remain acceptable.

8. Results

8.1 Dose Rates over Filled Cells Dose rates directly above cells are effectively a function of fill height, number of upwardly exposed containers and stacked height. This analysis has shown that it is unlikely that contact dose rates on top of the vaults will exceed 100 mR/hr. Even when filled four levels high with each HIC at 400 R/hr the average dose rate above the vaults is slightly under 100 mR/hr, with localized hot spots marginally over 100 mR/hr.

8.2 Skyshine vs. Distance The spreadsheet in Attachment G evaluates Skyshine based on the assumption that the central 15 cells are filled with 400 R/hr contact dose rate containers, and the peripheral cells are filled with 125 R/hr contact dose rate containers.

8.3 Wall Shielding Assessment The Attachment G spreadsheet shows that the dose rate on the lower radiation side of the shield wall remains ~ 1mR/hr even with the outer vaults filled with HICs up to 125 R/hr on contact.

9. Conclusions Analyses in this calculation demonstrate the following:

1. The central cells could be filled with 400 R/hr contact dose rate containers, and the peripheral cells filled with 125 R/hr contact dose rate containers, and the dose rates outside of the LLRWSF, both onsite and offsite, would meet dose rate limits and goals. In fact, this is a likely upper bound on expected containers, and substantial decay in storage would reduce the likelihood of approaching the calculated exterior dose rates.

2. Dose rates immediately over a cell filled with 400 R/hr contact containers could approach high radiation conditions (> 100 mrem/hr). Cells filled to less than 4 layers high would have significantly lower dose rates over the cells, and be expected to have proportionally lower external dose effects.

3. Intermittent doses are higher than those calculated in PM-0759 but are still acceptable. 4. The calculated dose rate to the nearest offsite residence location is less than 1 mrem/year, even

with the bounding source assumptions. 5. Realistically, dose rates outside of the building from Skyshine are unlikely to exceed 10% of the

calculated values, given more realistic HIC contact dose rates and decay effects. 6. Dose rates in the immediate vicinity of the walls will be proportional to container contact dose

rates in the near vicinity, and are considered predictive, though multiple containers are assumed to contribute.

7. Results from this calculation could be used to predict doses to 40CFR190 receptors, but in any case these doses are expected to be small compared to dose goals and very small compared to regulatory limits.

paul.reichertText BoxOf the above 241 R/hr dose, Co-60 contributes ~45%. Fission product contribute 1/3, and based on other mixes evaluated, cannot dependably displace Co-60. Therefore, an all Co-60 assumption will be used. This conclusion also applies to otheractivation products.

Since the Co-60 fraction from the 1.17 and 1.33 MEV photons is 1.11E4 mR/hr, and the design analysis is for 400 R/hr, forconservatism, the source is increased by 400/111 or 3.6. Additionally the new containers have a 5 foot diameter, and thecontainers analyzed in PM-759 had a 4.5 foot diameter. Therefore, the total correction is 3.6*(5/4.5)^2 = 4.5.

Single HIC MCNP Geometry: Nominal Container with waste treated as 5 feet in diameter and 6 feet high. Left view is section through a container with surface at 1 inch from waste and at 1 meter. The former is used as a contact. To the right is a plan view. The detecting surface are on the waste surface, 1 inch, and 1 meter away. Doses are determined based on particles crossing these surfaces. The horizontal lines are used to axially segment these surfaces to calculate axial peaking. This MCNP run forms the basis for determine photons/sec required for a 400 R/hr contact dose container.

A top of this shield is used as to create a surface source file recording the position, direction, energy, and particle weight for photons leaving the top. The source is used later to perform skyshine analyses. Separate runs are made and dose rates above the cell calculated for 1, 2, 3, and 4 layers of 4 containers.

Single PBAPS LLRWSF Waste Cell Source Particle Display: This display verifies that the source particles are, in fact, started in the waste packages.

Single PBAPS LLRWSF Waste Cell Collision Display: This display shows photon collisions, in the containers, in surrounding shielding, and to a limited extent, in the air in the cell. The display depth is selected so that back wall collisions are not shown.


PBAPS LLRWSF Simplified Geometry for Skyshine Analysis (Inside Building): These section and plan views show the LLRWSF, simplified to only include the storage cell area. This maximizes the dose rates calculated near the building

Surface Source Effect Illustration While cells and walls are shown, the effect of the filled cells is based on an array of the surface sources derived in the cell model. The plan view to the left is below the two foot thick cell shield caps. The plan view to the right shows a source particle display that illustrates the source array effects. The net effect of this array is checked to confirm that it is consistent with the results for doses over individual cells.


PBAPS LLRWSF Simplified Geometry for Skyshine Analysis (Outside Building): To calculate skyshine dose effects a cylinder and a series of spherical surfaces surround the building. These surfaces are used both for particle splitting and as surface crossing detectors. The horizontal ground surfaces is segmented by the cylinder and spheres to yield average doses in rings surrounding the LLRWSF. The spherical surfaces are also used, up to a limited height, to calculated doses vs. distances .
