Intake Structure The Intake Structure and the accompanying discharge tunnels are shown on the figure below. This figure demonstrates that the Intake Structure (and the tunnels) are founded deeper than the base of the Upper Clay. The concern with these structures is that the lateral extent of the excavations is not clear from the construction drawings (i.e.. there was no as-built drawing that showed whether the excavation was stabilized by a sloped excavation wall or by sheeting or by a combination of construction methods). Also, the as-built cross-sections show a 1.5 ft to 3 ft clay fill layer that was, apparently placed during the backfill of the Intake Structure and Intake/Discharge Tunnel area. This layer was reported tied into the upper portion of the Upper Clay to the east and the lower portion of the Upper Clay to the west. It is believed, however, that the "tie in" to the west could not exist after the Intake/Discharge Canal was constructed since this appears to have resulted in the excavation of the clay. It is also likely that the "tie in" to the east can currently exist because it appears the excavation for the Turbine Building and, possibly the Intake/Discharge Canals resulted in the excavation of the Upper Clay to the east. | Intake Structure The Intake Structure and the accompanying discharge tunnels are shown on the figure below.

Introduction This Radiological Preliminary Assessment Report (PAR) and Site Investigation Report (SIR) addresses radiological concerns at the Oyster Creek Nuclear Generating Station (OCNGS). it was assembled, based upon discussions with NJDEP, as part of a request for a deferral of radiological ISRA investigations and remediations, in order to postpone issues of federal preemption and ISRA applicability until decommissioning of the OCNGS. It relies on an extensive database of historical information gathered by the seller, as well as more recent information assembled as part of buyer's due diligence. It does not duplicate all of the information already assembled and submitted to NJDEP on non-radiological issues, some of which may nonetheless be useful to NJDEP. It is submitted without waiving the issues of ISRA applicability and federal preemption raised in GPU Nuclear's application pending before NJDEP. The terms "radiological concerns", "radiological AOC(s)", "area(s) of concern", and "AOC(s)", as used throughout this document, mean any area of concern involving radiological substances regulated by the federal Nuclear Regulatory Commission (NRC) as a "source", "special nuclear" and/or "by product" material, as such terms are defined in and to the extent regulated under the Atomic Energy Act. By "Decommissioning" we mean the complete retirement and removal of OCNGS from service and the restoration of the Site on which OCNGS operates, as well as any planning and administrative activities incidental thereto, including but not limited to (a) the dismantlement, decontamination, storage, and/or entombment of the Plant, in whole or in part, and any reduction or removal, whether before or after termination of the NRC license for the Plant, of radioactivity at the Site, and (b) all other activities necessary for the retirement, dismantlement and decontamination of the Plant, all as regulated by, or required to comply with, all applicable requirements of the Atomic Energy Act and the NRC's or its successor's rules, regulations, orders and pronouncements thereunder, the NRC Operating License for OCNGS and any related decommissioning plan (see, e.g., 10 C.F.R. Parts 50.75, 50.82, 51.53, and 51.95)." Radiological monitoring activities associated with the OCNGS have focused on certain target radionuclides, particularly Cs- 137 and Co-60 and to a lesser extent Sr-90, as trend indicators for radiological contamination. Although there are literally hundreds of radioisotopes present at the plant, mostly in the active fuel in the reactor (most of which have short - seconds to days- half lives), because the fission and activation process is essentially a constant, physically defined process, the ratios between the various longer lived isotopes tend to be fairly constant, particularly when compared with time to similar portions of the process. Thus, radwaste and water transportable long-lived activity in the plant process streams changes little over time. Because of this, a few easily measured radionuclides can be used as surrogate indicators of the entire mix. NRC regulations require detailed analysis of various waste streams including the lower activity, and hard-to-detect nuclides. These periodic analyses provide convincing radioisotopic ratio data that show that the use of the surrogate indicators is an effective tool. When this mixture
ratio data is combined with the values of the NRC default soil guideline limits for decommissioning, the mixture information clearly shows that the unusual and hard to detect isotopes will not contribute significantly to dose to a member of the public or plant workers if remediation decisions are based on the concentrations of the surrogate indicators. Throughout this report, the existing conditions of radionuclide concentrations in soils are compared to the NRC decommissioning default guideline concentrations. This is intended to provide some indication of the limited extent of eventual remediation required when the plant eventually enters decommissioning. However, the NRC decommissioning soil guideline concentrations are not relevant to an operating nuclear power plant. The very existence of the Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) and the soil guidelines recognizes that conditions at operating facilities are not and will not be always consistent with the decommissioning criteria. This is clearly recognized as acceptable for continued operation by the NRC. During operation, the plant is expected to control effluents and maintain the dose to the public and plant workers at As Low As Reasonably Achievable (ALARA) levels. The presence of small amounts of plant related radioactivity in on-site soils or groundwater does not represent a significant or even measurable dose to the public or the plant workers. Throughout this report it is shown that the radionuclide activity currently in the soils at the Oyster Creek plant are not impacting the offsite environment. Doses to plant workers from the limited activity in the soils are also insignificant. The NRC residual activity guidelines assume that a family lives, grows food, and has a drinking water well, etc. on the property. The dose assessment is based on this scenario, and doses are limited to 25 mrem to this resident farmer family. This scenario is impossible at an operating plant. Workers do not live here, they do not grow food crops, and the drinking water is carefully monitored and shown to be unaffected, and is not withdrawn from shallow wells in the highest affected soil areas Even if all of the dose in the resident scenario was from the direct radiation from the activity in the soil, this equates to a dose rate of approximately 0.003 mrem per hour. Workers in the plant routinely enter areas where dose rates are 100,000 times higher than this. The areas where radiological impacts to soils are the greatest, e.g. in the vicinity of the old radwaste surge tank and the condensate storage tank, are not characterized by dose rates of 0.003 mrem per hour. The radioactive materials actually inside the tanks themselves are creating dose rates in the vicinity of the tanks that are thousands of times higher than 0.003 mrem per hour. Far more radiation dose would be accumulated by the plant workers removing the soils as a consequence of the proximity to the contained sources nearby than could ever be avoided by removal of the few thousandths of a mrem per hour being contributed by the soil activity. This Radiological PAR/SIR also documents the fact that any radionuclide contamination of the on-site soil or groundwater at the OCNGS has not impacted the off-site environment. This conclusion is supported by the results of an ongoing Radiological Environmental Monitoring Program that has spanned a period of more than 33 years and has resulted in the collection of more than 40,000 samples of air, surface water, ground water, rain water, sediment, fish, clams, crabs, vegetables and soil. Independent
environmental monitoring programs conducted by the NJ Department of Environmental Protection and the US Nuclear Regulatory Commission have confirmed these results. The results of this off-site Radiological Environmental Monitoring Program satisfy any requirement for a Baseline Ecological Evaluation and Ecological Risk Assessment as specified by the Technical Requirements for Site Remediation (NJ.KC. 7:26E).

Non-radiological areas of concern were addressed in a separate Preliminary Assessment, which was submitted to the NJDEP in December of 1999. Accordingly, this PAR does not address concerns at the adjacent Forked River site (which is addressed in ISRA Case No. E98542) nor does it address non-radiological concerns. I. Present a history of ownership and operations at the industrial establishment, in tabular form, from the time the site was naturally vegetated or utilized as farmland in accordance with NJI.A.C. 7:26E-3.1(c) L.i. (attach additional sheets as necessary). For the purposes of discussion, the property is divided into two portions. Parcel I is identified as the developed portion of the site located primarily within the "horseshoe" formed by the Intake and Discharge Canals west of Route 9 (identified as the Oyster Creek Nuclear Generation Station or "OCNGS"). Parcel 2 is identified as the area located cast of Route 9 which is primarily heavily vegetated and undeveloped (See Appendices L and M).

To the extent available the site history shall include an evaluation of the following sources of information: (1) Sanborn Fire Insurance Maps; (2) MacRae's Industrial Directory; (3) Title and Deed; (4) Site plans and facility as-built drawings; (5) federal, state, county and local government files; (6) The Department Geographic Information System. (7) and any additional sources which may be available for a specific site.
Site history is frequently an item where preliminary assessments are incomplete. The Industrial Site Recovery Act requires that a diligent inquiry be made., researching the site history back to January 1, 1932. Common answers to this question have inchuded 'Unknown", or "We are only a tenant on the site and have no knowledge of prior site history". Neither of these answers satisfies the requirement for a due diligent inquiry. To avoid having a PA found incomplete by the Department due to insufficient information, the site history must be researched. The following are ways of obtaining information regarding site history: title searches: contacting the local and county health officials and municipal agencies (for example, local fire and police departments, and local planning, zoning, adjustment boards); requesting any information these public agencies may have on the specific location; and, interviewing long time neighbors of the industrial establishment. Tenants should always request information from the landlord. The applicant should always document any attempts to locate this information to support a claim that a diligent inquiry has been conducted. If the prior site history demonstatems that the current building was built on vacant unimproved 2 02/26/00, 10:21 AM

APPENDIX A SITE HISTORY
APPENDIX A: QUESTION 2A DESCRIPTION OF PAST INDUSTRIAL OPERATIONS Western Portion of Property or OCNGS: The property inside the "horseshoe" (bounded on the east by US Route 9, and on the north, south and west by the Intake and Discharge Canals), was purchased by Jersey Central Power and Light Company (JCP&L), a subsidiary of GPU, Inc., from Norman C. and Elsie H. Finninger (husband and wife) on 1M28/61. This portion of the site is where the Oyster Creek Nuclear Generating Station (OCNGS) is presently located. The approximately 132-acre property is located in Lacey Township as a portion of Block 1001, Lot 4 (Deed Book 2144, pg. 484). Approximately 12.01 acres of land located in Ocean Township, along the south bank of Oyster Creek (Block 41, Lot 43) was also purchased as part of that transaction. Prior to construction of the OCNGS, the site was vacant and undeveloped. JCP&L purchased the land for the purpose of constructing the OCNGS. JCP&L initiated construction of the OCNGS in December of 1963 and commercial operation began on December 23, 1969. JCP&L operated the OCNGS until 1980 when GPUN, another subsidiary of GPU, Inc., assumed responsibility for operations. GPUN continues to operate the OCNGS for JCP&L, doing business as GPU Energy. Eastern Portion of Property: JCP&L purchased the "Finninger Farm Property", located across US Route 9 and east of the OCNGS, from NOR-RU-EL, Inc. on 6/28/66. The 548.07 acre property is located in Lacey Township as Block 100, Lots 1-20 & 20.01 and Ocean Township as Block 63, Lot 7 (Deed Book 2600, pg. 352). Prior to that purchase, the portion of the property located in Lacey Township (536.03 acres) was used for the raising of beef cattle while the 12.04 acre parcel located in Ocean Township was undeveloped. JCP&L purchased an undeveloped 25.25-acre parcel (Lacey Township Block 101, Lot 1) located adjacent to the north side of the Finninger Farm Property, from Mayer Construction Company on 3/8/71 (Deed Book 3110, pg. 357). As part of the land acquisition for the construction if the intake canal for the OCNGS, JCP&L purchased a 2.01 acre undeveloped parcel (Lacey Township Block 138, Lot 2) from Charles R. Pearl and Marie D. Pearl on 1/18/66 (Deed Book 2555, pg. 411), and an undeveloped lot comprising 1.01 acres (Lacey Township Block 139, Lot 11) from Wilnor Realty Company on 11/17/65 (Deed Book 2539, pg. 369).
APPENDIX B: QUESTION 2B DESCRIPTION OF MOST RECENT OPERATIONS Western portion of Proverty: OCNGS consists of a single boiling-water nuclear reactor and a turbine-generator to produce electrical power. This equipment and auxiliary support structum are located within the area bounded on the east by U.S. Route 9 and on the north, south and west by the intake/discharge canal. Three basic steps are involved in the process of producing electricity at the OCNGS. First, heat produced by fission in the nuclear reactor converts high purity water to steam. Second, the steam is used to drive a turbine so that some of the energy in the steam is converted to mechanical energy. Third, the turbine is connected to a generator which converts the mechanical energy of the rotating turbine into electrical energy. Saltwater from Barnegat Bay is used to cool the steam exhausted from the turbine and to condense the steam back into water. This condensed high purity water is returned from the main station condensers to the heat source to be converted into 'steam again to continue to drive the turbine. Eastern Portion of Property. The eastern portion of the site is primarily heavily vegetated and largely undeveloped. JCP&L/GPUN have used the property in the following manner: I. To deposit excavated/dredged soil and sediment during the construction of the intake and discharge canals for the OCNGS during the 1960's.
- 2. As a source of topsoil for re-vegetation projects on and around the OCNGS.
- 3. As an Environmental Laboratory (in buildings formerly located on the property) from 1975-1988.
- 4. To deposit dredged material resulting from periodic maintenance dredging in the intake and discharge canals. This material was all deposited at the location of the existing 17.5 acre upland Confined Disposal Facility during dredging projects in 1978, 1984 and 1997. The Confined Disposal Facility is discussed in Question 5, AOC-38.
- 5. As a location for environmental monitoring activities including continuous air monitoring, ground water monitoring and the planting of gardens to provide vegetables for radiological analyses.
- 6. The Barge Unloading Facility (AOC-7), located along the south shore of Oyster Creek (Discharge Canal) adjacent to U.S. Route 9, has been used to deliver large components, such as the turbine rotor, to the OCNGS. This facility is currently used on an intermittent basis by the Ocean County Engineering Department to load reef construction materials (concrete and used tires) onto vessels for delivery to artificial reefs in the Atlantic Ocean.

I APPENDIX C RADIOACTIVE SUBSTANCES/WASTE INVENTORY I I
APPENDIX C: QUESTION 3 Radioactive Substances/Waste Inventory The vastly predominant location for radioactive material is in the reactor building, in two locations. All remaining locations together contain one millionth or less of the activity in the reactor building. The reactor vessel contains the majority of this activity most of which is short lived (half-lives of seconds to days). Fuel performance/bum-up computer calculations show that there we hundreds of different radionuclides in active fuel. However, for practical purposes of radiation protection, the isotopes of most interest in active fuel are the short lived noble gases and iodines (e.g. Xe-133, Xe-135, Kr-88, 1-131, 1-133, etc.). The reactor is inside a full pressure suppression containment and contains 577 used / highly irradiated fuel elements. The second location in the reactor building that contains most of the remaining activity is the spent fuel pool. The spent fuel pool is used to store spent fuel for decay and cooling. The spent fuel pool is inside a secondary containment and currently contains 2420 spent fuel elements of various ages after discharge from about 1.5 years to about 30 years. Following a relatively short period of decay, the nuclide content of the discharged fuel decreases by several orders of magnitude. Major isotopes of interest following this cooling / decay period are Co- 60, which is present as a surface film, and Cs-137 which is in the fuel. Vastly smaller amounts of radioactive material are elsewhere throughout the plant. Short lived noble gases, activation gases (N-16) and radioiodines are present in the turbine building as a result of carry over and degassing into the main steam system. The Augmented Off-gas (AOG) building receives the non-condensable gases from the turbine / condenser system through the 30 minute delay line. The same radionuclides, less decay, (therefore no significant N-16 for example) are present in the AOG building. The New and Old Radwaste buildings contain liquid and solid waste processing. Therefore, dominant radionuclides in this building are consistent with those transported through depressurized water: soluble and particulate fission and activation products. The nuclide mixes associated with the solid waste streams are evaluated periodically per NRC requirements in 10 CFR 61. The majority of the activity in these buildings consists of Co-60, Cs-137, and Fe-55. The low-level Radwaste storage building contains waste that is packaged and staged for disposal and materials and equipment that is stored for re-use. Therefore, the activity in this building is consistent with the solid waste streams in the Radwaste processing buildings, and is dominated by Co-60, Cs-137, and Fe-55. The Radiological instrument calibration facility has several sealed sources of Cs- 137 that provide the dose rates needed to calibrate survey meters etc.

A number of these operational units and their associated appurtenances contain or transport radiological materials/wastes as part of the process. Each of these systems that contain or transport radiological materials/wastes, which pose as potential Areas of Concern (AOC) as defined in N.J.A.C. 7:26E, is listed below. Non-radiological areas of concern were addressed in a separate Preliminary Assessment, which was submitted to the NJDEP in December of 1999. I.A. BULK STORAGE AREAS AND APPURTENANVCES ABOVEGROUND STORAGE TANKS AND APPURTENANCES (AOCs 1- 4) AOC - 1A Condensate Storage Tank The Condensate Storage Tank ("CST") is a 525,000-gallon tank that provides bulk storage of condensate for use throughout the plant. The tank is located outside the west wall of the Turbine Building. Water for filling the CST is supplied from the demineralized water system. The CST provides a surge volume for the condensate system. The make-up and spill valves transfer water between the CST and the condensate system to absorb volume changes in the condensate system. The CST is located on a concrete rim support and has no secondary containment-OCNGS conducted a soil-sampling program for gamma-emitting radionuclides in the area of the CST and its associated Pump Shack. The results of the sampling program indicate detectable concentrations of Cobalt-60 (Co-60). Four (4) of the thirty-four (34) soil samples were above the Nuclear Regulatory Commission's ("NRC-) default decommissioning facilities of 3.8 picoCuries/gram (pCi/g). Co-60 was detected at concentrations of 157 pCi/g, 22 pCi/g, 20 pCi/g I 02/28/00, 1:25 PM
APPENDIX F: QUESTION 5 DESCRIPTION OF POTENTIAL AREAS OF CONCERN WITH PHOTODOCUMENTATION and 6.8 pCi/g. The two samples with the highest concentrations were associated with a valve and line leak and the two remaining concentrations were associated with bottom leakage from the CST. All samples in AOC-IA were collected in 1991. In addition to the soil data noted above, two monitoring wells (W-5 and W-6) are located hydrogeologicafly cross gradient of the area. The monitoring wells are sampled semi-annually as part of the Radiological Environmental Monitoring Program (REMP). Each well was sampled for gamma-emitting radionuclides associated with fission processes and tritium. The analytical results from these wells during 1999 indicated only tritium was detected in MW-5 at a concentration of 380 pCi/I (USEPA Drinking water standard for tritium is 20,000 picoCuries per liter (pCi/I)). No other plant specific radionuclides were detected in either well. Detailed information pertaining to the analytical samples and results referenced above can be found in Attachment I of this Appendix and in Appendix N.

AOC - 4A Former Waste Surge Tank The Former Waste Surge Tank is a 100,000-gallon aluminum tank situated on a concrete rim support. The tank was historically used to store wastewater from the operational portion of the plant prior to treatment. The tank was removed from service in 1982 when a leak was detected in the base of the tank. Impacted soils were excavated and removed. OCNGS c,,onducted a soil-sampling program for gamma-emitting radionuclides associated with fission processes (e.g., Co-60 & Cs-137) in the area of the Surge Tank. The results of the sampling program indicate detectable concentrations of Co-60 and Cs-137. Of the one hundred seventeen (112) samples collected in 1982, 1992, and 1999 twenty-seven (27) exceed the NRC decommissioning guideline for for Co-60 and twenty-seven (27) of the samples exceeded the guideline for Cs-137. Concentrations of Co-60 ranged from below the method detection level to 1,100 pCi/g and concentrations for Cs- 137 ranged from below the method detection level to 390 pCi/g These maximum concentrations were the result of a spill in 1992. Detailed information pertaining to the analytical samples and results referenced above can be found in Attachment I of this Appendix and in Appendix N. OCNGS samples groundwater on a routine basis as part of the REMP. In 1999, fifteen (15) monitoring wells were sampled in March and again in September. The results of the analysis of the thirty (30) samples collected from the on-site groundwater monitoring well network revealed that Tritium was the only plant specific radionuclide detected. Tritium was found in eight of the wells in March and five of the wells in September with concentrations ranging from 140 pCi/L to 580 pCi/L well below USEPA's drinking water standard of 20,000 pCifL. These concentrations also reflect a significant decrease from the concentrations detected in 1998.

UNDERGROUND STORAGE TANK(S) (AOC-5) AOC -5 Waste Drop Tank The Waste Drop Tank (UST Registration No. NJ0043067, expiration 6-30-01) is a 2.00G-gallon lined fiberglass UST that is located immediately outside the southern wall of the Material Warehouse. The floor drain system in the Material Warehouse is connected to the Waste Drop Tank. The floor drains have been directed to the Waste Drop Tank since the construction of the facility. Drums of petroleum and other chemical products (non-radiological) are stored in the portion of the warehouse serviced by the drain system. The purpose of the Waste Drop Tank is to act as a secondary containment sump in the event of a spill or leak from the drums. As such, the tank was constructed with a chemically resistant internal lining. The Waste Drop Tank has no discharge lines; any material collected in the tank would be pumped out within 48 hours for off-site disposal. The tank was pumped out once when mop water from cleaning the warehouse floor was pushed into the tank drains and allowed to accumulate in the tank. Once discovered, the water was pumped out and disposed at an off-site wastewater treatment facility in accordance with 9 02/28/00, 1:25 PM

There are no radiological materials or wastes stored in these areas. In 1999, the OCNGS conducted a soil-sampling program in the fuel storage area. This area is located immediately adjacent the eastern drainage swale. The results of the sampling program indicate detectable concentrations of Co-60 and Cs-137. However, the concentrations detected were below the NRC decommissioning guidelines. Twenty (20) soil samples were collected late in 1992 and an additional thirteen (13) soil samples were collected in 1999. Analytical results from the soils indicated that none of the samples obtained in 1999 contained Co-60 and the highest concentration of Cs-137 was reported at 0.111 pCi/g, which is similar to the normal environmental concentration for this nuclide. The results of the 1992 samples indicated the highest concentrations of Co-60 reported was 0.0996 pCi/g and the highest concentration of Cs-137 was 0.211 pCi/g.

AOC-15 Southern Drainage Area The Southern Drainage Area collects water from the southern parking lots, Heli-Port and administration building. There are no radiological materials or wastes stored in the aforementioned areas. In 1999, the OCNGS conducted a soil-sampling program for the gamma-emitting radionuclides associated with fission processes (e.g., Co-60 & Cs-137) in the southern portion of the facility, which ultimately discharged its storm water to the southern drainage swale. The results of the sampling program indicate detectable concentrations of Cs-137 in three (3) of the eleven (I1) samples collected. However, all concentrations detected were below the NRC's soil guideline at decommissioning of 11 pCi/g Analytical results from the soils indicated that the highest concentrations of Cs-137 detected was 0.030 pCi/g, which is consistent with normal environmental background for this nuclide. Co-60 was not detected in any of the soil samples analyzed.

STORM SEWER COLLECTION SYSTEMS (AOC-16) AOC-16 Storm Sewer Collection Systems The storm sewer collection system at the OCNGS consists of a series of catch basins and underground storm water pipelines, which receive and transport. storm water throughout the station to various discharge points. Storm water discharges at the OCNGS are directed to the following: a The Intake/Discharge Canal in accordance with the permit limits and monitoring requirements of NJPDES Permit No. NJO005550, 0 a trench located adjacent to a wooded area, north of the Main Gate Entrance (discussed in AOC-13); 0 the water mound located at the northern portion of the OCNGS (discussed in AOC-18); and, 0 a storm drainage area south of the Main Gate Entrance (discussed in AOC-15). NFA - The Storm Sewer Collection System discharges are regulated under NJPDES. In addition, the drainage swales do not receive surface flow from production areas. Finally, information nthe receiving waters, the Canal. is discussed in detail below. 22 02/28/00, 1:25 PM
APPENDIX F: QUESTION 5 DESCRIPTION OF POTENTIAL AREAS OF CONCERN WITH PHOTODOCUMENTATION SURFACE WATER BODIES (AOC-17) AOC - 17 Intake/Discharge Canal The Intake/Discharge Canal was excavated during the construction of the OCNGS in the 1960's to provide cooling water for the facility operations. The Canal receives water from the Barnegat Bay, Oyster Creek and Forked River. Water from the Canal is ultimately discharged back to the Barnegat Bay. The soil and sediment excavated from the canal were used as fill at the site. Prior to the excavation of the canal, the land west of U.S. Route 9 was vacant and undeveloped, while the land east of U.S. Route 9 was used for beef cattle farming. Maintenance of the canal has included dredging activities in 1978, 1984, and 1997. Analytical results of dredge spoils sampling and analysis conducted as part of GPUN's request for interim closure of an Upland Confined Disposal Facility are discussed in AOC-38. Discharges to the canal are discussed in AOC-24. Oyster Creek Nuclear Generating Station samples the surface water, sediments, and aquatic life on a regular basis. In 1998 twenty-eight (28) surface water samples were obtained and analyzed for gamma-emitting radionuclides. One gamma-emitting nuclide, potassium-40 (K-40) was detected in 27 of the 28 analysis performed. Tritium (H3) activity was detected in one sample. Both of these radionuclides are naturally occurring and commonly found in salt water at or above the observed concentrations. No other plant specific radionuclides were detected in surface water samples. Five gamma-emitting radionuclides were detected in the 8 sediment samples collected during 1998. Four of these radionuclides, beryllium-7 (Be-7), potassium-40 (K-40), radium-226 (RA-226) and thorium-232 (Th-232), are naturally occurring and not attributable to plant effluents. Cesium-137 (Cs-137), which is a fission product, was detected in both background and indicator samples. Cs-137 was widely distributed and detected in considerable abundance as a result of fallout following atmospheric weapons tests and the 1986 Chernobyl accident. Cs-137 was released in small quantities from the plant in liquid effluents in past years. The results of the sediment-sampling program indicate that the presence of Cs-137 in the sediment of the facility discharge canal and nearby portions of the Barnegat Bay may be attributable in part to past liquid discharges from the facility. A review of sediment analysis results form 1994 - 1998 period shows Cs-137 was detected in 82% of the background and only 60% of indicator samples. However, Cs-23 02/28/00, 1:25 PM
APPENDIX F: QUESTION 5 DESCRIPTION OF POTENTIAL AREAS OF CONCERN WITH PHOTODOCUMENTATION 137 concentrations detected at the two indicator stations, which are closest to the facility discharge point, show concentrations consistently higher than those found at background stations. During the previous five years, the mean concentration of Cs-137 at background stations was 0.032 pCi/g-dry, while the average concentration at the two stations closest the effluent discharge was 0.093 pCi/g-dry. In addition, during the five year period, the highest concentration of Cs-137 at an indicator station was 0.240 pCi/g-dry, which was detected in March 1996. The highest concentration found at a background station during the same five year period was 0.067 pCi/g-dry. It is important to note that the highest concentration of Cs-137 observed in sediment (0.240 pCi/g-dry) was only slightly above the 0. 180 pCi/g-dry Lower Limit Detection specified by the Nuclear Regulatory Commission and only 12% of their Reporting Level for Cs-137 in fish and broad leaf vegetation (2.0 pCi/g-wet). Over the years, there has been a dramatic reduction in liquid discharges from the facility and there have been no routine discharges of liquid radioactive wastes since 1989. As a result of this reduction in liquid effluent, as well as the ongoing natural radioactive decay process, the level of Cs-137 in sediments continues to decrease. Concentrations of Co-60 were not detected in either indicator or background station sediment samples during 1998. No radionuclides attributable to effluent from the facility were found in samples of clams, crabs and fish collected during 1998. Detailed information pertaining to the analytical samples and results referenced above can be found in Appendix N. Defer Activities until Decommissioning based on the following information:
- Limited extent of radionuclides detected in the surface water, sediments, and aquatic life samples; and
- Limited concentration of radionuclides detected in the surface water, sediments, and aquatic life samples; AOC-18 Water Mound The water mound is a canal filled with fresh water for the purpose of maintaining a pressure head on the fresh water aquifers to prevent the intrusion of estuarine water from the Oyster Creek intake canal into the ground water. It was constructed in 1967 in accordance with the Second Interim Order issued by the New Jersey Board of Public Utility Commissioners on April 22, 1966.
24 02/28/00, 1:25 PM
APPENDIX F: QUESTION 5 DESCRIPTION OF POTENTIAL AREAS OF CONCERN WITH PHOTODOCUMENTATION Located on the south bank of the intake canal, just west of U.S. Route 9, the water mound is approximately 1,200 feet long, 30 feet wide at the top, and 15-20 feet wide at the bottom. The original depth was 8 feet with overflow drains to ensure a minimum water depth of 1.5 feet. Silt has accumulated in the water mound over the years, reducing the depth considerably. More than 30 years of sampling eleven monitoring wells located around the water mound have demonstrated that there has been no salt-water intrusion into local aquifers attributable to the operation of the intake canal for the Oyster Creek Station. NFA for this potential AOC because the water mound does not receive surface flow from areas containing radiological materials or wastes. D. DISCHARGE AND DISPOSAL AREAS WASTEWATER COLLECTION SYSTEMS - SEPTIC SYSTEMS, SEEPAGE PITS (AOC 20) AOC-19 Former On-site Wastewater Treatment Facility Prior to the connection to the Ocean County Utilities Authority in approximately 1982, sanitary wastes at the OCNGS were directed to a former on-site treatment facility. The former treatment facility was located approximately 200 fi south of the Reactor Building. Discharges to the treatment facility included floor drains in the following: the main office building, the Turbine Building bathrooms, the "clean" (non-radiologically contaminated) portion of the Turbine Building, and the plant engineering building (or the auxiliary office building). Treated liquids discharged to the canal at Discharge Serial No. (DSN) 004 under DSW Permit No. NJ 0005550. Solids were pumped into a steel underground holding tank. Olsen's Septic Service, a local contractor, pumped the tank out on an as-needed basis. Following the connection to the municipal treatment system, aboveground structures associated with the treatment facility were removed. In 1999, the OCNGS collected four soil samples around the former on-site wastewater facility. The results of the sampling program indicated detectable concentrations of Cs-137 in two (2) of the four (4) samples at concentrations 0. 11 pCi/g and 0.036 pCi/g below NRC decommissioning guidelines at decommissioning of I I pCi/g. Co-60 was not detected in any of the soil samples 25 02/28/00, 1:25 PM
APPENDIX F: QUESTION 5 DESCRIPTION OF POTENTIAL AREAS OF CONCERN WITH PHOTODOCUMENTATION analyzed. Detailed information pertaining to the analytical samples and results referenced above can be found in Attachment I of the Appendix and Appendix N. NFA - The former on-site Wastewater Treatment System received wastewater from the non-radiological portions of the site. The treatment system was cleaned prior to demolition. In addition, groundwater in the area of the former system is monitored on a regular basis. The analytical results from the site-wide monitoring program can be found in Appendix N. AOC-20 Seepage Pit The domestic water system at the OCNGS withdraws water from a 300 ft deep well finished in the Kirkwood Aquifer. This water is filtered through the plant's domestic water treatment system. Approximately 2,000 gallons per day are backwashed from this treatment system to a 6 ft by 9 ft concrete cylinder with a perforated bottom that is located within 125 feet of the plant's Discharge Canal. Presently, the plant's water treatment system is a fully containerized, mobile treatment system provided by a water treatment contractor. Originally, "hard coal filters" were used to filter the domestic water for the OCNGS, however, these were abandoned in favor of the more modem trailer-mounted system. The present trailer-mounted system uses sand as a filtering media in lieu of the original hard coal system. After water from the 300-fl deep Kirkwood well is processed by the plant's domestic water treatment system, it is also used as raw water for replenishing plant systems. To be used for this purpose, domestic water must be highly purified and demineralized. A second mobile treatment system equipped with ion exchange resins is used for this purpose. Periodically, it is necessary to exchange this second trailer-mounted fully containerized, mobile system with a regenerated system. The schedule for this exchange is not regular or calendar driven, but is dependent upon the quality of the output water. Operating experience to date has shown that a new trailer is needed about once every two months. To ensure that the water in the new system upon arrival at the OCNGS does not affect the high purity requirements of the OCNGS, it is necessary to flush the new system with domestic water that has already been filtered by the sand beds in the first trailer. Flushing is accomplished only when a new trailer-mounted system arrives on site. This new system flush consists of approximately 1,000 gallons of demineralized water, which is discharged to the 6 ft by 9-f4 concrete cylinder previously described. This flushing operation occurs each time that a new trailer arrives on site. 26 02/28/00, 1:25 PM
APPENDIX F: QUESTION 5 DESCRIPTION OF POTENTIAL AREAS OF CONCERN WITH PHOTODOCUMENTATION All of these activities are regulated by NJPDES Discharge to Ground Water Permit No. NJ0101966. This permit requires annual sampling of the backflush of the domestic water treatment system. Samples of the backflush are collected prior to discharge to the 6-ft by 9-ft concrete cylinder, representing the worst case, pre-dilution conditions. The specific sampling location is the pre-treatment building, 160 ft north of the 6-ft by 9-ft cylinder. Required analyses are pH, total dissolved solids (TDS), iron and manganese. There are no permit limits for these parameters; however, reporting to the NJDEP is required if the measured values exceed the historical range. In addition, a quarterly grab sample is required prior to discharging the regenerated treatment system flush to the 6-ft by 9-ft concrete cylinder. The specific sample location is the sample outlet just west of the pre-treatment building. Although no limits are imposed, analyses for pH, TDS, total iron, chlorides, total sodium and total petroleum hydrocarbons are required. The above-described discharges have almost no effect on groundwater quality. The direction of groundwater flow in the vicinity of the discharges is towards the OCNGS Discharge Canal and the Discharge Canal is within 125 feet of the discharge to groundwater. Therefore, only a very small volume of groundwater can actually receive this discharge and that volume eventually discharges to surface water (the Discharge Canal). In 1999, the facility conducted a soil-sampling program for the gamma-emitting radionuclides associated with fission processes (e.g., Co-60 & Cs-137) in the area of the Seepage Pit. The results of the sampling program indicate detectable concentrations of Cs-137. However, the concentrations detected were below the NRC decommissioning guideline of II pCi/g. Three (3) of the five (5) samples of Cs-137 obtained were below the method detection limit. The highest concentration reported for Cs-37 was 0.084 pCi/g, which is consistent with normal background for this nuclide. Co-60 was not detected in any of the five samples. Detailed information pertaining to the analytical samples and results referenced above can be found in Appendix N. Defer Activities until Decommissioning based on the following information:
# Limited extent of radionuclides detected in the soils (probably background); + Concentrations of the radionuclides detected in the soils were below the NRC's soil guideline for decommissioning facilities;

The Laydown Area is a gravel/soil area at which a temporary building was located in 1991 and 1992. Grit blasting was performed in the building. A four-foot high soil pile measuring approximately 50 ft by 25 ft is located in this area. The soil pile was generated during the construction of the new office building in 1994. OCNGS conducted a soil-sampling program for the gamma-emitting radionuclides in the area of the above referenced tank. The results of the sampling program indicate detectable concentrations of Cs-137. However, the concentrations detected were below NRC decommissioning guideline. Four (4) of the five (5) samples for Cs-137 obtained were below the method detection limit. The highest concentration reported for Cs-37 was 0.037 pCi/g, which is consistent with normal environmental background for this nuclide. Co-60 was not detected in any of the samples. Detailed information pertaining to the analytical samples and results referenced above can be found in Appendix N. Defer Activities until Decommissioning based on the following information:
- Limited extent of radionuclides detected in the soils (probably backgroud),

AOC-23 Undeveloped Area East of U.S. Route 9 The majority of the Property consists of undeveloped land located east of U.S. Route 9. This area (Finninger's Farm) was formerly used for raising beef cattle until purchase by JCP&L in 1966. Historical and recent uses for this area include:
- To deposit excavated/dredged soil and sediment during the construction of the intake and discharge canals for the OCNGS (AOC- 17);
- As a source of topsoil for re-vegetation projects on and around the OCNGS;
- As an office and marine-life sample processing facility (in a building formerly located on the property) for environmental consultants studying fish and other marine organisms in Barnegat Bay from 1975 through 1988. These activities included the preservation of samples of marine life in 10% formalin and 40% isopropanol.
- To deposit dredged material resulting from periodic maintenance dredging in the intake and discharge canals. This material was all deposited at the location of the existing 17.5 acre Upland Confined Disposal Facility during dredging projects in 1978, 1984 and 1997 (addressed in AOC-38); and,
- As a location for environmental monitoring activities including continuous air monitoring, ground water monitoring and the planting of gardens to provide vegetables for radiological analyses.
NFA for this potential AOC because the areas listed above have been addressed as separate AOCs or the activities conducted (source of topsoil and environmental monitoring activities) do not present potential impacts to soil/groundwater; and, there was no industrial activity in the remaining portion of the property. NON-CONTACT COOLING WATER DISCHARGES The OCNGS is authorized to discharge non-contact cooling water from the following outfalls in accordance with the requirements of NJPDES Permit No. NJ0005550 which was issued 10/21/94 and is effective 12/01/94 through 11/30/99 (renewal application submitted 05/28/99): 29 02/28/00, 1:25 PM
APPENDIX F: QUESTION 5 DESCRIPTION OF POTENTIAL AREAS OF CONCERN WITH PHOTODOCUMENTATION AOC-24A DSN 001 - Main condenser non-contact cooling water Discharge DSN 001 is located at the southern side of the land bridge that separates the Intake and Discharge Canals. Samples are collected at the outfall of DSN 001 for thermal parameters, and in the main condenser discharge tunnel just east of the chlorine monitor shed prior to the outfall or at the outfall of DSN 001 for all other parameters and reported monthly. The circulating water system supplies cooling water to the main condenser to condense low-pressure turbine exhaust steam. The circulation system consists of the circulating water system pumps and condenser along with a vacuum priming system. The four circulating water pumps each have a designed capacity of 11 5,000-gpm. Under normal operation, the four pumps deliver a total of 460,000 gpm, 450,000-gpm is supplied to the main condenser and 10,000 gpm is diverted to the Turbine Building Cooling Vater heat exchangers. The pumps discharge into 66-inch lines which direct flow to a 10.5 ft. square tunnel to the turbine building west wall. Circulating water enters and leaves the three condenser shells through 6-ft. lines. On the discharge side of the main condenser, the 6-ft. lines join into a 10.5-ft. square tunnel, which leads the water to the discharge canal. The tunnel itself serves as a seal well, since its roof is below minimum water level in the discharge canal. The 5-fi deicing recirculation tunnel runs below the water level back to the intake structure. The total depth of the intake structure is variable. The deepest part of the structure is approximately el. -2 1'. The eastern half of the structure is slightly shallower at approximately el. -18'. The structure appears to be founded on the Cohansey Formation. The clay in this area is shallower than el. -18.

APPENDIX F: QUESTION 5 DESCRIPTION OF POTENTIAL AREAS OF CONCERN WITH PHOTODOCUMENTATION ACTIVE OR INACTIVE PRODUCTION WELLS AOC-25 Production Wells Two production wells on site are installed in the Kirkwood Formation. The South Well (Permit No. 33-1095) is 300 feet deep, located near the Diesel Generator Building and is used for potable water, and as a source of make-up water for plant systems (AOC-IA). The North Well (Permit No. 3323652) is 162 feet deep, located north of the North Parking Area and is used for potable water and as a source of make-up water for plant systems (AOC-IA). The South Well is sampled on a quarterly basis as part of the routine REMP. The results for 1998 showed no plant specific radionuclides in water samples from the well. NFA for this potential AOC because the wells are in use and are tested in accordance with the requirements of the Safe Drinking Water Act; and the wells are maintained within secure areas. F BUILDING INTERIOR AREAS WITH POTENTIAL FOR DISCHARGE BUILDING INTERIOR AREAS (AOCs 26 - 37) AOC -26 Reactor Building The Reactor Building stands approximately 150 feet high with 42 feet extending below grade. It serves as a secondary containment unit and houses the primary containment dry well as well as the reactor vessel and its auxiliary systems. In addition, all refueling equipment, and the spent fuel storage pool are all located inside the Reactor Building. The dry well which houses the reactor vessel, is constructed of high-density reinforced concrete with an inner steel liner measuring 120 ft. high and 70 ft. in diameter. The Reactor Building has been designed as a secondary containment system for all operations conducted in the building. The building was designed and constructed specifically to eliminate the potential release of contaminants to the surrounding environment. The building walls are 3ft. thick reinforced concrete. The Reactor Building foundation is a 10-ft. thick steel reinforced concrete slab. Underlying the slab is a waterproofing system that consists of the following: a 3-inch 33 02/28/00, 1:25 PM
APPENDIX F: QUESTION 5 DESCRIPTION OF POTENTIAL AREAS OF CONCERN WITH PHOTODOCUMENTATION concrete leveling slab; a waterproofing membrane which extends to approximately 15-ft. below ground surface (bgs); and a 2-inch concrete protective slab. Groundwater in the area of the Reactor Building is generally located at 6 to 8 ft. bgs. As noted above, the reactor floor is approximately 42 feet below grade. Consequently, a breach in the Reactor Building floor or walls would result in groundwater entering the building. Since no groundwater has permeated the Reactor Building floor or walls, the integrity of building has been maintained. Four soil samples were collected within the vicinity of the Reactor Building in 1999. Concentrations of Co-60 were detected in three (3) of the four (4) soil samples at concentrations raging from 0.75 pCi/g to 1.75 pCi/g. Concentrations of Cs-137 were detected in all four (4) samples ranging from 0.145 to 10.3 pCi/g.

AOC - 27 Turbine Building The Turbine Building houses the turbine-generator, control room, main condensers, power conversion equipment and auxiliary systems. The turbine-generator consists of one high-pressure turbine, three low-pressure turbines, a generator and an exciter. Steam is supplied to the high-pressure turbine from the reactor. After being used to drive the turbines and generator, the steam is condensed in the main condensers and returned to the reactor vessel in the form of water through the condensate and feedwater pumps. There are two sets of tunnels entering or exiting the Turbine Building. These tunnels are used to provide non-contact cooling water to the condensers. The water is subsequently returned to the canal through the second set of discharge tunnels. The Turbine Building has been designed as a secondary containment system for all operations conducted in the building. The building was designed and constructed specifically to eliminate the potential release of contaminants to the surrounding environment. The building walls are 3ft. thick reinforced concrete and extend from the basement levels to the operating floor about 23 ft. above grade. The Turbine Building foundation is 6 ft. to 8-ft. thick steel reinforced concrete slab. The Turbine Building mat or foundation overlaps the Reactor Building mat where the two buildings abut. As noted above, the Turbine Building's bottom floor is approximately 23 feet bgs. Consequently, a breach in the Turbine Building floor or walls would result in groundwater entering the building. A detailed description of the building and information regarding the potential release of contaminants from this building is discussed in detail in Appendix M "Theoretical Release Study.

AOC-28 Stack The ventilation stack is 368 feet high with 26 feet extending below grade. The stack provides ventilation for the Reactor Building, Turbine Building and Radwaste facilities and is part of the facility's off-gas system. The air ejector and off-gas systems are designed to remove noncondensables from the main condensers and provide for their safe dispersal to the environment. Three steam jet air ejectors and one mechanical vacuum pump are used in a conventional arrangement for removing noncondensables from the main condensers. The nature of the noncondensables however, is quite different from that found in fossil-fueled plants: gaseous hydrogen and oxygen formed by radiolytic decomposition of the reactor water are the major constituents amounting to more than twice the volume of air in -leakage to the main condensers. The principal radioactive noncondensables are short-lived isotopes of nitrogen that occur normally in the boiling water reactor cycle. Ultimately, the system is designed to remove air and noncondensables from the main condensers, and delays radioactive materials in the hold-up pipe for decay. The exhaust from this system is discharged to the Exhaust Tunnel System and ultimately to the stack. The base of the stack is comprised of a 7-ft. steel reinforced concrete pad. The foundation includes the typical 3 part waterproofing system (leveling slab, waterproof membrane, and protective slab). The waterproofing system may extend around the entire foundation. A single sump (Sump No. 1-12) underlies the stack foundation. The sump has a 4-ft. diameter and is located west of the center of the stack. Two primary tunnels attach to the stack from the Reactor Building/Turbine Building and the Old/New Radwaste buildings. These tunnels are described above in AOC - 9. 36 02/28/00, 1:25 PM

AOC-29 Exhaust System Pipes Exhaust gases from the main condensers are transported to the Exhaust Stack via two pipes. The primary pipe starts as a 38-inch line from the condensers and is processed through the air ejectors. The pipe from the ejectors is a 48-inch line that is used as a 30-minute holdup line to delay decaying radioactive materials. The line from the ejectors leaves the Turbine Building and extends underground to the Exhaust Stack. The second line from the steam packing exhauster and the mechanical vacuum pumps starts as a 30-inch line and expands to 36-inches at the Exhaust Stack. This line also leaves the Turbine Building and proceeds underground to the Exhaust Stack. Once in the Exhaust Stack, the gases from both lines are filtered and monitored prior to dispersion.

The building was historically used for wastewater treatment. However, these operations were relocated to the New Radwaste Building. Currently, operations in the building include water purification and process waste disposal packaging. In addition, equipment used during plant operations for waste compaction and waste transfer is housed in the building. The Old Radwaste Building has been designed and constructed specifically to eliminate the potential release of contaminants to the surrounding environment. The building is a single story reinforced concrete structure with a two-story penthouse. A small basement area is located in the central portion of the building and a pipe tunnel extends from this building to the New Radwaste Building and the Exhaust Stack. The building is comprised of three primary sections, see Figure, two with shallow foundations and the third section (middle section) having a deep foundation. Each of the three sections is constructed on a reinforced concrete mat. Beneath the mat, the building has an impermeable liner that is situated above a concrete leveling pad.

AOC - 31 New Radwaste Building The New Radwaste Building is located northeast of the Reactor Building. The building is used for wastewater purification/treatment processing and waste disposal packaging. The New Radwaste Building has been designed and constructed specifically to eliminate the potential release of contaminants to the surrounding environment. The building foundation is constructed of approximately 4 ft. of steel reinforced concrete underlain by a 2-inch protective concrete layer, a waterproof membrane, and a 2-inch concrete leveling mat. The thickness of the leveling mat is variable (from 2 to 4 inches); hence the use of the term "approximately" is used in describing the foundation thickness. In 1999, the OCNGS conducted a soil-sampling program for the gamma-emitting radionuclides around the New Radwaste Building. The results of the sampling program indicate detectable concentrations of Co-60 and Cs-137. However, the concentrations detected were below the NRC decommissioning. Twenty-seven (27) samples were collected in 1981 and 1999. The highest concentration reported for Co-60 was 1.5 pCi/g and for Cs-137 the highest concentration 39 02/28/00, 1:25 PM

The building is used for staging radioactive materials prior to disposal or re-use. The Low Level Radwaste Building has been designed and constructed specifically to eliminate the potential release of contaminants to the surrounding environment. This building has a reinforced concrete walls and base mat. The upper walls and ceiling are steel truss work construction, with precast concrete exterior panels on the walls, while the lower walls are steel reinforced concrete. The top of the base mat of the building is at an elevation of 25 ft. above mean sea level. Information regarding the potential release of contaminants from this building is discussed in detail in Attachment I of this Appendix and in Appendix M "Theoretical Release Study". A detailed description of the building, sumps and tunnels is also provided in the aforementioned Appendix. The facility conducted a soil-sampling program for the gamma-emitting in the area of the Low Level Radwaste Storage Building. The results of the sampling program indicate detectable concentrations of Cs-137 in one of the four (4) samples obtained. However, the concentrations detected were below the NRC decommissioning guidelines. Analytical results for the samples indicated that three (3) of the four (4) samples were below the method detection limits for Cs-137.

AOC-39 Condensate Transfer Overboard Discharge Event On September 17, 1998, approximately 148,800 gallons of condensate transfer water was discharged to the Circulating Water discharge tunnel via the Fire Protection System, and ultimately released to the Oyster Creek discharge canal. Following the release, an investigation of potentially impacted surface water, sediments and biota (clams) was conducted. In surface water, tritium levels in the condenser intake were slightly elevated (330 +/- 110 pCi/L). The maximum tritium concentration observed in surface water samples (16,000 pCi/L) did not exceed the USEPA drinking water limit (20,000 pCi/L), and USNRC effluent limitations were not exceeded. Cobalt-60 was the only gamma emitting nuclide to be detected in surface water, detected in only one of 23 samples, downstream of the 30" header (2.0 +/- 1.2 pCi/L). All sediment samples from the Barnegat Bay and the intake canal were less than the limit of detection. In Oyster Creek sediment, Co-60 was detected in 4 of 16 samples. The maximum sediment concentration was 0.056 pCi/g, well below the NRC guideline of 3.8 pCi/g. All sediment samples were less than or equal to those observed in REMP samples prior to the release. Clams in Barnegat Bay were also sampled and determined to be non-detect for Co-60; this was consistent with previous REMP 44 02/28/00, 1:25 PM
APPENDIX F: QUESTION 5 DESCRIPTION OF POTENTIAL AREAS OF CONCERN WITH PHOTODOCUMENTATION sampling results. Tritium was not found in clams collected near the mouth of Oyster Creek, however, low levels attributable to natural background were found in clams from Stouts Creek to the north and Manahawkin Bay to the south. NFA:
- The concentrations of radionuclides measured in sediment, surface water and clams immediately following this event did not exceed any effluent limitations, drinking water standards or decommissioning guidelines;
+ Reduction in concentrations of radionuclides detected in surface water over time; and
- Reduction in concentrations of radionuclides in sediments.

APPENDIX F: QUESTION 5 DESCRIPTION OF POTENTIAL AREAS OF CONCERN WITH PHOTODOCUMENTATION AOC-40 Torus System Leak (May 2, 1980)
== Description:== The leakage of Torus system water from the containment spray heat exchangers into the station's service water discharge resulted in the release of an unknown quantity of radiologically contaminated water. The leakage that occurred during periods of system testing which occurred for each containment spray system approximately twice per month for 15 to 30 minutes. The Bureau of Radiation Protection was notified of the release, and when facility personnel assumed this satisfied NJDEP notification requirement, no other NJDEP offices were immediately advised. The notification process was immediately reviewed with facility personnel to prevent this oversight from reoccurring. In addition, as part of the facility's REMP it monitors a composite sampler immediately downstream of discharge point 004. The samples are obtained daily and analyzed weekly for gamma-emitting radionuclides and tritium. Information pertaining to surface water, sediment, and aquatic life sampling can be found in AOC-17. Resolution: The containment spray heat exchangers were completely retubed. Defer Activities until Decommissioning based on the following information:
- Estimated concentrations of the radionuclides released were well below effluent limitations; and
- Limited extent of radionuclides released to the discharge canal.
- Conservative calculations assuming worst case conditions demonstrated that the isotopic concentration of the discharge were well below the effluent limitations specified by the NRC;
- As described in the discussion of AOC-17 (Intake/Discharge Canal), extensive sampling of surface water, sediments and aquatic life has demonstrated that CO-60 was not detected in any environmental samples and Cs-137 was only found in sediments at concentrations slightly above the lower limit of detection.

APPENDIX F: QUESTION 5 DESCRIPTION OF POTENTIAL AREAS OF CONCERN WITH PHOTODOCUMENTATION AOC - 41 Northern Parking Area Soils from inside the protected area were excavated in 1982 to evaluate the construction of a building and later to adjust topography for paving. These soils contained detectable radionuclides. Following petition for approval from the NRC, these soils were relocated to the area that is now the north parking lot, between the Low Level Radwaste Storage Facility and the north domestic water pump house, placed in trenches, covered with soil and paved over. Based on extensive soil sampling conducted at the time, concentrations in this area are not expected to exceed the NRC decommissioning concentration guidelines due to mixing during relocation, and decay since placement. Defer Activities until Decommissioning based on the following information:
- Lack of impact to groundwater, the AOC has been capped; and
- Restricted access to the AOC.
AOC-42 Main Fuel Oil Storage Tank/ Berms The OCNGS excavated and removed soils to complete several projects throughout the site. If during the course of soil excavation contaminated soils are encountered, the soils are sampled and analyzed for fission related radionuclides. Soils containing low levels, but detectable, were placed in piles or in berm on-site. The berm surrounding the main oil storage tank, the berms behind the dilution pumps, the berm on the south side of the Independent Spent Fuel Storage Installation (ISFSI) and the berm around the waste surge tank have been constructed using these soils. In 1999, the OCNGS conducted a soil-sampling program for the gamma-emitting radionuclides associated with fission processes (e.g., Co-60 & Cs-137) in the berm and soils around the MTOST. The results of the sampling program indicate detectable concentrations of Co-60 in twelve (12) of the seventeen (17) samples collected. However, all concentrations detected were below the NRC's soil guideline at decommissioning of 3.8 pCi/g. The maximum concentration of Co-60 was 0.95 pCi/g. Concentrations of Cs-137 were detected in fifteen (15) of seventeen (17) samples. The maximum concentration of 3.2 pCi/g is below the NRC guideline of 11 pCi/g. Detailed information pertaining to the analytical samples and results referenced above can be found in Appendix N. 47 02/28/00, 1:25 PM
APPENDIX F: QUESTION 5 DESCRIPTION OF POTENTIAL AREAS OF CONCERN WITH PHOTODOCUMENTATION Defer Activities until Decommissioning based on the following information:
- Limited extent of radionuclides detected in the soils surrounding the building;
- Concentrations of the radionuclides detected in the soils were below the NRC's soil guideline for decommissioning facilities;
- Lack of impact to site wide groundwater; and
- Restricted access to the AOC.

APPENDIX H DISCHARGE HISTORY OF HAZARDOUS SUBSTANCES AND WASTES I.
APPENDIX H: QUESTION 7 Discharge History of Hazardous Substances and Wastes May 2,1980 (AOC.40) On May 2, 1980, the leakage of Torus system water from the containment spray heat exchangers into the station's service water discharge resulted in the release of an unknown quantity of radiologically contaminated water. The leakage that occurred during periods of system testing which occurred for each containment spray system approximately twice per month for 15 to 30 minutes. Conservative calculations assuming worst case conditions demonstrated that the isotopic concentrations of the discharge were well below the effluent limitations specified by the USNRC. The Bureau of Radiation Protection was notified of the release, and when facility personnel assumed this satisfied NJDEP notification requirement, no other NJDEP offices were immediately advised. The notification process was immediately reviewed with facility personnel to prevent this oversight from reoccurring. In addition, as part of the facility's REMP it monitors a composite sampler immediately downstream of discharge point 004. The samples are obtained daily and analyzed weekly for gamma-emitting radionuclides and tritium. Information pertaining to surface water, sediment, and aquatic life sampling can be found in AOC-17. March 2, 1992 (AOC-4A/B) The Former Waste Surge Tank is a 100,000-gallon aluminum tank situated on a concrete rim support. The tank was historically used to store wastewater from the operational portion of the plant prior to treatment. The tank was removed from service in 1982 when a leak was detected in the base of the tank. Impacted soils were excavated and removed. OCNGS conducted a soil-sampling program for gamma-emitting radionuclides associated with fission processes (e.g., Co-60 & Cs-137) in the area of the Surge Tank. The results of the sampling program indicate detectable concentrations of Co-60 and Cs-137. Of the one hundred seventeen (117) samples collected in 1982, 1992, and 1999
twenty-eight (28) exceed the NRC's guideline for decommissioning facilities of 3.8 pCi/g for Co-60 and twenty-seven (27) of the samples exceeded the guideline of 11 pCi/g for Cs-137. Concentrations of Co-60 ranged from below the method detection level to 1,100 pCi/g and concentrations for Cs-137 ranged from below the method detection level to 390 pCi/g. These maximum concentrations were the result of a spill in 1992. Some soils associated with the release were excavated, removed and disposed of in accordance with NRC regulations. The Surge Tank was removed from service and the lines were emptied cleaned, flushed and capped in-place September 17, 1998 (A OC - 39) On September 17, 1998, approximately 148,800 gallons of condensate transfer water was discharged to the Circulating Water discharge tunnel via the Fire Protection System, and ultimately released to the Oyster Creek discharge canal. Following the release, an investigation of potentially impacted surface water, sediments and biota (clams) was conducted. In surface water, tritium levels in the condenser intake were slightly elevated (330 +/- 110 pCi/L). The maximum tritium concentration observed in surface water samples (16,000 pCi/L) did not exceed the USEPA drinking water limit (20,000 pCi/L), and USNRC effluent limitations were not exceeded. Cobalt-60 was the only gamma emitting nuclide to be detected in surface water, detected in only one of 23 samples, downstream of the 30" header (2.0 +/- 1.2 pCi/L). All sediment samples from the Barnegat Bay and the intake canal were less than the limit of detection. In Oyster Creek sediment, Co-60 was detected in 4 of 16 samples. The maximum sediment concentration was 0.056 pCi/g, well below the NRC guideline of 3.8 pCi/g. All sediment samples were less than or equal to those observed in REMP samples prior to the release. Clams in Barnegat Bay were also sampled and determined to be non-detect for Co-60; this was consistent with previous REMP sampling results. Tritium was not found in clams collected near the mouth of Oyster Creek, however, low levels attributable to natural background were found in clams from Stouts Creek to the north and Manahawkin Bay to the south.
APPENDIX I REMEDIATION ACTIVITIES
APPENDIX 1: QUESTION 8 Description of Previous or Current Remediation Activities 1.0 Former Waste Surge Tank and Associated Lines (AOC-4A & 4B) The Former Waste Surge Tank is a 100,000-gallon aluminum tank situated on a concrete rim support. The tank was historically used to store wastewater from the operational portion of the plant prior to treatment. The tank was removed from service in 1982 when a leak was detected in the base of the tank. Impacted soils were excavated and removed. OCNGS conducted a soil-sampling program for gamma-emitting radionuclides associated with fission processes (e.g., Co-60 & Cs-137) in the area of the Surge Tank. The results of the sampling program indicate detectable concentrations of Co-60 and Cs-137. Of the one hundred seventeen (117) samples collected in 1982, 1992, and 1999 twenty-eight (28) exceed the NRC's guideline for decommissioning facilities of 3.8 pCi/g for Co-60 and twenty-seven (27) of the samples exceeded the guideline of 11 pCi/g for Cs-137. Concentrations of Co-60 ranged from below the method detection level to 1,100 pCi/g and concentrations for Cs-137 ranged from below the method detection level to 390 pCi/g. These maximum concentrations were the result of a spill in 1992. Some soils associated with the release were excavated, removed and disposed of in accordance with NRC regulations. The Waste Surge Tank was removed from service and the lines were emptied cleaned, flushed and capped in-place. 2.0 Northern Parking Area (AOC-41) Soils from inside the protected area were excavated in 1982 to adjust the topography prior to paving. These soils contained detectable licensed radionuclides. Following petition for approval from the NRC, these soils were relocated to the area that is now the north parking lot, between the Low Level Radwaste Storage Facility and the north domestic water pump house, placed in trenches, covered with soil and paved over. Based on extensive soil sampling conducted at the time, concentrations in this area are not expected to exceed the NRC decommissioning concentration guidelines due to mixing during relocation, and decay since placement.
3.0 Berms (AOC-42) The OCNGS excavated and removed soils to complete several projects throughout the site. If during the course of soil excavation contaminated soils are encountered, the soils are sampled and analyzed for fission related radionuclides. Soils containing low levels, but detectable, were placed in piles or in berms on-site. The berm surrounding the main oil storage tank, the berm behind the dilution pumps, the berm on the south side of the Independent Spent Fuel Storage Installation (ISFSI) and the berm around the waste surge tank have been constructed using these soils. In 1999, the OCNGS conducted a soil-sampling program for the gamma-emitting radionuclides associated with fission processes (e.g., Co-60 & Cs-137) in the berm and soils around the MFOST. The results of the sampling program indicate detectable concentrations of Co-60 in twelve (12) of the seventeen (17) samples collected. However, all concentrations detected were below the NRC's soil guideline at decommissioning of 3.8 pCi/g. The maximum concentration of Co-60 was 0.95 pCi/g. Concentrations of Cs-137 were detected in fifteen (15) of seventeen (17) samples. The maximum concentration of 3.2 pCi/g is below the NRC guideline of 11 pCi/g.

1.0 INTRODUCTION
URS Greiner Woodward Clyde (URSGWC) has prepared this report for the GPU Nuclear Corporation (GPU), US Route 9, Forked River, NJ. The scope of work for this project was to: Evaluate selected structures to determine if there is the potential for a release of radionuclides from a breach in the floor slab to impact soil and/or groundwater.
- 2. Evaluate probable flow paths for a release using 2 dimensional groundwater modeling and, if applicable, particle tracking analyses.
This scope of work is based on initial conversations between Ms. Beverly Good, Mr. Terry Hanlon and Mr. Jay Vouglitois of GPU and Mr. Michael Carnese (URSGWC). The scope of work was subsequently modified based on the initial review of the data and subsequent conversations between Ms. Good and Mr. Carnese. The structures originally to be evaluated, based on initial conversations, included the following:
- The New Radwaste Building; The Old Radwaste Building;
- The Reactor Building; The Turbine Building; and One unidentified tunnel.
During the course of reviewing the construction drawings it was determined that the unidentified tunnel was, in fact, a tunnel system that includes the following:
" New Radwaste to Old Radwaste; " Old Radwaste to Exhaust Stack; " Turbine and Reactor Buildings to Exhaust Stack; " The Intake Tunnel; and, " The Discharge Tunnel.

It was also discovered that the Intake Structure and Discharge Structures were constructed to a depth that potentially impacted the site hydrogeology because the depth of excavation of these structures resulted in the excavation of the clay layer separating the water bearing formations (the Cape May Formation and the Cohansey Formation). The change in the site stratigraphy, based on these excavations, had the potential to impact the planned 2-dimensional groundwater models by changing the hydrogeology between the major structures of concern (the Turbine Building, the Reactor Building, the Old Radwaste Building, etc.) as defined in the initial scope of work a~d the primary potential receptor, the Intake/Discharge Canal It was, therefore, necessary to add these structures to: 1) the summary of the site excavations; 2) the summary of the as-built drawings; 3) the geologic cross-sections; and 4) the two dimensional model cross-sections. This report is organized as follows: " Section 2: Summarizes the review of the as-built and excavation drawings; " Section 3: Summarizes the stratigraphy, hydrogeology and the impacts ofthe construction of selected structures on the stratigraphy and hydrogeology. This section also includes an evaluation of structures with foundations below the water table using fracture flow analysis. " Section 4: Discusses the results of the construction of two 2-Dimensional models using MODFLOW and MODPATH. " Section 5: Presents a summary of the previous sections with conclusions and recommendations; " Section 6: Discusses the limitations of the use of this material by GPU and others; " Section 7: References, including a list of the as-built drawings and other drawings provided by GPU. 1-2 linoJFCtSv.OAOIV,..,*m WISQEu PM URS Greiner Woodward-Clyde LIRS Greiner Woodward-Clyde 1-2
2.0 REVIEW OF CONSTRUCTION DRAWINGS The first task was a review of the as-built excavation drawings and the as-built foundation construction drawings. The purpose of the review was to: I. Determine the absolute elevation of the depth of the structure, including associated tunnels, if appropriate;
- 2. Determine the depth to which the initial construction excavation occurred (i.e., did the excavation extend deeper and wider than the structure).
- 3. Evaluate the depth of the structure relative to the local stratigraphy (i.e., the impacts on hydraulic communication between the Cape May Formation and the Cohansey Formation through excavation of the Upper Clay);
- 4. Evaluate the depth of the structure relative to the average depth of the water table aquifer.
- 5. Compile the information in a format useful for evaluating the potential impacts of the structures on the localized groundwater flow paths.
The interpretation of the "as-built" drawings, especially the excavation summary drawings was subject to some interpretation because of the following observations:
- The scale on the as-built drawings often was not "as-shown" because of changes in the size of the drawings when reproduced. It appears the drawings were, at some point, stored on microfilm and then reproduced from the microfilm. The reproduction was not to the scale of the original drawings.
" The survey (monuments) or structural reference points on the historic as-built excavation drawings are not on the current site plans (i.e., the survey monuments used for construction are not the current survey monuments used to register recent drawings). In addition, the building outlines on the as-built excavation drawings do not always agree with the current dimensions or layout of the buildings. " The as-built excavation drawings were all from different dates. The sequence of the drawings and the references to areas already backfilled indicates the excavations for the major structures listed above took place in several stages. URSGWC constructed a composite of the excavations, extrapolating (interpreting) as necessary between drawings of different areas or between drawings that indicated multiple excavations URS Greiner Woodward-Clyde 2-1 1-OMýý-P-- ý I- 4 13PM
in the same area (e.g., The area of the Stack appears to have been excavated as part of the excavation for the Reactor and Old Radwaste Buildings, partially backfilled and later excavated again to the depth of the foundation of the Exhaust Stack).
" The limits of the excavations as shown on the as-built drawings did not always coincide with stratigraphic information from soil borings advanced as part of subsequent geotechnical or environmental investigations. " The method of stabilizing the excavation was not always included on the excavation drawings. For example, there was no detailed excavation drawing for the Intake/Exhaust Tunnel. The standard slope used to maintain a stable excavation on most drawings was 1.5 to 1. There were, however, indications that shoring was used in place of sloping in selected areas. It could not be determined if the Tunnel excavation was one of these areas.
URSGWC compiled the as-built historical drawings into two drawings (Figures 2-1 and 2-2). Figure 2-1 shows the below grade vertical extent of the structures of concern, including the tunnel system. The Exhaust Tunnel System and the Discharge Structure locations have been transcribed from as-built drawings as accurately as was possible. Some of the finer details that would not impact the conclusions of this study have not been included. Features too small to accurately represent on a 1:20 scale drawing or features overshadowed by larger structures (e.g., sumps vs. tunnels) were not transcribed from the individual construction drawings to the composite drawing. These features would be too small to be evaluated on a 2 or 3 dimensional groundwater flow model (Section 4). A summary of the drawings reviewed as part of this study is included in Section 7, References. Figure 2-2 shows the estimates of the vertical and horizontal limits of the excavations implemented during construction. Conservative assumptions regarding the extent of excavations were made in areas where no as-built cross-sections were available based on the engineering practices demonstrated in areas with cross-sections. For example, all cross-sections indicated that for large excavations the sides were sloped at 1.5 ft. horizontal to I ft. vertical (1.5:1). Also, lacking additional information, URSGWC assumed excavation walls were sloped at 1.5:1. URSGWC attempted to resolve the conflicts between the soil boring logs and the as-built construction drawings.

2.1 APPARENT HISTORICAL EXCAVATION SEQUENCE The construction excavations, exclusive of the New Rad-Waste Building and the Intake
& Discharge Canal are summarized in three drawings: " Reactor and Turbine Area Excavation Plan and Sections, Dwg. 4007-3, 9/22/64; " Intake and Turbine Area Excavation and Backfill Plan & Sections, Dwg. 4006-2, 4/29/65; and " Reactor Area Backfill Details, Dwg. 4010-2, 8/22/65 All three drawings were revised for "As-Built Conditions" on 5/5/70. While no drawings indicate the sequence of the excavations, the Intake and Turbine Area Excavation drawing and the Reactor Area Backfill Details refer to completed excavations in the Reactor and Turbine Areas (this includes the Old Radwaste Building).
Reactor and Turbine Area Excavation Plan and Sections The Reactor and Turbine Area Excavation Plan indicated the entire Turbine Building footprint plus a buffer was excavated to elevation (el.) -13' 0". The Turbine Building area, exclusive of the deeper structures such as the Intake/Discharge Tunnel and sump pits, was backfilled to el. 6'-5". The slope of the excavation sidewalls, where shown, was at 1.5:1. This means the excavation extended a minimum of 54 ft beyond the base of the excavation. The dimensions of the excavation exceed the dimensions of the current building. The rectangles shown below show the relative size of the Turbine Building excavation (left) vs the relative size of the Turbine Building (right).

The buffer zone surrounding the excavation was, presumably, the additional area needed for construction related activities. Because of the proximity of the Reactor Building to the Turbine Building, the slope of the walls of the Reactor elevation infringed on the limits of the Turbine Building excavation as shown in the sketch below (note: the elevations shown are the approximate elevations of the depth of the excavation beneath each building): 4f Turbine Bldg Reactor Bldg.
-13'-6" -29'- 6" The detail section of the Reactor/Radwaste Buildings excavation demonstrates the Reactor Building excavation was to a depth of el.-29' 6" and that the Reactor Building was founded on original ground. Because the Reactor Building excavation was significantly deeper than the Turbine Building, the excavation was sloped upwards to el.
-13'0". The detailed sections also indicate the Old Rad-Waste Building excavation extended to el. 13'0", well below the depth of the foundation mat of the building. As with the Turbine Building, the horizontal limits of the base of the Reactor Building and Old Rad-Waste Buildings, is significantly larger than the size of the actual building footprints. The Turbine/Reactor excavation extended beyond the eastern limits of the Old Radwaste Building. This area was also excavated to a depth of approximately el. -14'. The invert of the deep portion of the Old-Radwaste Building slab is at el. +3' 6". 2.2 REACTOR BUILDING The pertinent features of the Reactor Building are summarized below. GreinerWoodwarci-Clyde URS Greiner URS Woodward-Clyde 2-4 24 a~ - in..,,. I, 1 Total Depth: The base of the 10 ft thick mat of the Reactor Building is at el. -29' 6". Approximately 52.5 ft below ground surface (assume ground surface elevation of +23' 0". The mat is, apparently, founded on Cohansey Formation (i.e., there is essentially no backfill beneath the mat). The Reactor Building is the deepest of all buildings on the Site. Foundation Construction: The Reactor Building mat is, as stated above, a 10 ft. thick steel reinforced concrete slab. Underlying the slab is a waterproofing system that consists of the following: 1) a 3 inch concrete leveling slab; 2) a waterproofing membrane; and. 3) a 2 inch concrete protective slab (see below). The waterproofing membrane apparently extends to an elevation of+5' 0" (with different construction details). SIMPLIFIED CROSS-SECTION OF FOUNDATION W/ WATERPROOFING

Sumps: Two sumps were identified on Dwg. 4097-7 (Reactor Building Foundation Plan and Sections). The invert of the sumps was shown as el. -23' 0". The invert of the Reactor Building mat is deeper in the areas of the sump, to maintain a total mat thickness of approximately 10 ft from the invert of the sump (i.e., mat depth of approximately el. - 33' 0". These sumps are small and so required the deepening of the mat in areas approximately 9 ft square. The sumps are not shown on the drawings or cross-sections. Backfill: As was stated above, the leveling slab appears to be founded on the Cohansey Formation, not backfill. Presumably, the additional excavation for the sumps was localized to the sump area (no excavation details were found). There are no excavation/backfill cross-sections in the sump areas.

2.3 TURBINE BUILDING The pertinent features of the Reactor Building are summarized below. Total Depth: The base of the 6 ft thick mat of the Turbine Building is at el. -6' 0". In the turbine areas the base is thicker (8 ft) therefore the base is deeper, el. -8' 0". The tunnel section of the building is at el. -14'. Please note that this conflicts with the maximum reported excavation depth of el. -13' as shown on the Turbine are as-built excavation drawing. The difference of one foot does not substantially impact the hydrogoelogic model. Foundation Construction: As stated above, the mat of the turbine building is either 6' or 8' thick steel reinforced concrete. The detail drawings show the same leveling slab, waterproofing membrane and water proofing membrane protection concrete as discussed in the Reactor Building construction section (the previous section). The excavation in the vicinity of the Turbine Building extended to approximately el. 13' 6" (near the completion depth of the Intake/Discharge Tunnel. The excavation cross-sections show the base of the tunnel structure to be founded on upper Cohansey. It appears the excavation did not extend deeper than the bottom of the tunnel.

Sumps: There are five sumps/pits in the turbine building. Three are small pits that are not shown on the summary figure, Figure 2-1. There is a pair of pits adjacent to the Intake/Discharge Tunnel that have inverts of el. -14' and el. -18 ft. These are shown on Figure 2-1 as a combined sump with multiple invert elevations. Backfill: As was stated above, the excavation drawings show the 8 ft and 6 ft mats were constructed on backfill. It appears the area of the Turbine Building was excavated to the planned depth of the intake/discharge tunnel, el. -14'-0". 2.4 OLD RADWASTE BUILDING The pertinent features of the Old Radwaste Building are summarized below. Total Depth: The total depth of the foundation for the Old Radwaste Building is variable (see below), including both shallow foundation and deep foundations. The shallow foundation portions are areas in which the top of the foundation slab is at el. 23' 0" (grade level). The bottom of the slab is el. 22' 4" to el. 21' 6", depending on the type of foundation construction. For the purpose of this report we will consider the average bottom of slab elevation for shallow foundation areas to be el. 22' 0". The bottom of the slab of the deep foundation portion of the building is el. 3' 6", exclusive of small area shown below. Variations in slab construction methods are discussed below.

We cannot resolve the differences. We have, therefore, used the base map provided by GPU for the base map on all plan view figures since the base map represents actual measurements not as-bualt construction documents. Foundation Construction: Much of the shallow foundation area, particularly the area east of the "deep foundation" portion of the building, is constructed with a variety of construction methods including:
- 8 inches of wire mesh reinforced concrete over 6 inches of gravel with a vapor barrier under the concrete;
- I ft 6 inches of steel reinforced concrete over 6 inches of gravel with or without a vapor barrier under the concrete; or
- 2 ft 6 inches of steel reinforced concrete over 6 inches of gravel with or without a vapor barrier under the concrete.
It is possible that there are additional variations on the designs discussed above. Detail drawings were not provided for the entire building. The foundation supports in these areas range from 2 ft by 2 ft steel reinforced grade beams (base at el. 21' 0") to steel reinforced footings (7 ft at base) founded at el. 15'. The floor is also segmented into several sections and so includes construction (i.e., expansion) joints. The construction joint detail shows the joints included an 8 inch thick poured joint filler. The detail did not show evidence of an underlying vapor barrier or water proofing membrane. The majority of the details reviewed for this report were from the eastern portion of the building, It is presumed that similar construction methods were used in the western portion of the building that has a shallow foundation. The foundation in the "deep foundation" portion of the building is 3 ft thick steel reinforced concrete and includes a water proof membrane. The maximum elevation to which the membrane extends could not be determined. The minimum elevation to which the membrane extends is el. 12' 0". The only variation in foundation elevation is in a shallower portion of the deep foundation portion of the building (see above) in which the slab thickness is reduced to 2 or 2.5 ft. Tunnels: There is a tunnel that extends from the Old Radwaste Building to the Exhaust Stack. This tunnel will be discussed as a separate section. 2-8 r.nnWcrsw.oa2w.,,*,e..,d,~ hvflflr. 13 UHS GreinerWooclwarcl-Clyde URS L~reiner Woodward-Clydle 2-8 1.o-0 7s*o 2*. * *,N,*.,.
Sumps: There is a minimum of one sump in the deep foundation portion of the building. In this area, the concrete thickness is maintained and so the bottom of the slab in the sump area is at el. 0' 0"(the elevation of slab minus elevation of the sump inside the building). There are two additional structures that may be sumps. There were no detailed cross-sections in this area; therefore, the depth of the sumps could not be determined. The sumps are small and have not been included in the final geologic and hydrogeologic cross-sections. Structures this size will not impact the model(s). Backfill: The excavation for this structure extended to el. -14. This means there is approximately 18 ft of fill beneath the base of the deep foundation section and approximately 36 ft of fill beneath the shallow foundation sections of the structure (exclusive of grade beams and footings). SIMPLIFIED EXCAVATION CROSS-SECTION (not to scale) er=120 ft. el. 3' 6" FILL TO EL. -14' 2.5 NEW RADWASTE BUILDING The pertinent features of the New Radwaste Building are summarized below. Total Depth: The foundation slab of the New Radwaste Building extends from el. 23' 6" to el. 19' 4". The base of the building is deeper in the sump areas or in the area of the tunnel to the Old Radwaste Building. The depth of a typical sump extends to el. 15' 4" (5 ft deeper than the normal slab. The bottom of the tunnel is at el. 7' 9" except in the area of the tunnel sump that extends to el. 3' 6".

Foundation Construction: The foundation is constructed of approximately 4 ft of steel reinforced concrete underlain by a 2 to 4 inch protective concrete layer, a water proof membrane, and a 2-inch concrete leveling mat. The thickness of the leveling mat is consistently 2 inches. The thickness of the protective layer is, as was stated above, variable (from 2 to 4 inches); hence, the use of the term "approximately" in describing the foundation thickness. The waterproof membrane appears to extend the height of the slab, sump or tunnel. Vertical waterproofing does not, however, include protective concrete. There is a note on one of the detail drawings stating the waterproof membrane was to be protected by fiberboard during backfilling of the excavation. Tunnels: There is a single tunnel leading from the New Radwaste Building to the Old Radwaste Building. The depth of the tunnel is, as was stated previously, el. 7' 9". A note on a detail drawing for the tunnel notes that it slopes downward towards the Old Radwaste Building. The finish elevation of the tunnel is not known because there were not detail drawings of the tunnel exclusive of those associated with the New Radwaste Building. Sumps: discussed above Backfill: There are no excavation drawings for the New Radwaste Building. The base of the slab and sumps is likely founded on fill of unknown thickness. Borings near the building suggest between 0 and 10 ft of fill that appears to be very similar to the Cape May formation. The base of the tunnel sump is at the top of the Upper Clay. This could have necessitated some excavation of the clay, perhaps on the order of 1-3 ft. The base of the tunnel, where it exits the south side of the New Radwaste Building, is approximately 2 ft above the top of the Upper Clay. URSGWC has assumed that the construction of the tunnel, near the New Radwaste Building, did not require any significant excavation of the Upper Clay (i.e., enough excavation to result in the change in the hydrogeologic characteristics of the Upper Clay near this structure). Without any information on tunnel construction methods or tunnel geometry (particularly where it enters the Old Radwaste Building), URSGWC URS Greiner Woodward-Clyde 2-10 Lwo- W-Pý
cannot determine if any excavation of the Upper Clay was required for other sections of the tunnel. 2.6 INTAKE STRUCTURE The pertinent features of the Intake Structure are summarized below. Total Depth: The total depth of the intake structure is variable. The deepest part of the structure is approximately el. -21'. The eastern half of the structure is slightly shallower at approximately el. -18'. The structure appears to be founded on the Cohansey Formation. The clay in this area is shallower than el. -18. In the figure presented below, the bottom of the fill is presumed to be the bottom of the intake structure (Dwg. 4006-2). SIMPLIFIED CROSS SECTION OF INTAKE STRUCTURE (not to scale) Discharge Tunnels Foundation Construction: The intake structure is generally constructed of 2 ft thick steel reinforced concrete. Detail drawings reviewed for this report did not indicate the presence of water proofing. Tunnels: The tunnels associated with this structure include the Intake Tunnel and electrical tunnel. The intake tunnel is discussed in Section 2.8.1. The electrical tunnel appears to be located at an elevation well above groundwater and so should not impact the conclusions of this report. Sum No sumps were observed on the drawings reviewed for this report. URS GreinerWoodward-Clyde 2-11
Backfill: The backfill, as seen in the cross-section presented above, does not appear beneath the Intake Structure. The clay fill layer is present (as shown above). The cross-section indicated the western limit of the clay layer is tied into the lower portion of the Upper Clay Formation. The clay fill layer then extends past the limits of the discharge tunnels and thins to 1.5 ft. The eastern terminus of the clay layer is the upper portion of the Upper Clay Formation. Additional details on the construction method and speculation regarding the function of this layer are presented in Section 2.8.1. 2.7 TUNNELS AND OTHER STRUCTURES Tunnels and, if necessary, tunnel segments are discussed individually in the following sections. 2.7.1 Intake/Discharge Tunnel The pertinent features of the New Radwaste Building are summarized below. Total Depth: The intake tunnel runs from the Intake Building to the Turbine Building. The interior of the intake tunnel is 10'6" by 10'6". The tunnel enters the Intake Structure from at approximately el.15'0". The Intake Tunnel slopes downward to el. 13'0" at the intersection with the Unit I Discharge Tunnel. From that point . the Intake and Discharge tunnel are a single structure with a maximum (top) el. of 13'0" and minimum (bottom) el. of 12'-O". The Unit I and Unit 2 Discharge Tunnels are nearly identical. Both tunnels have maximum elevations of 0'6", exclusive of the last 15 ft where the tunnel enters the Discharge Canal. At the terminus, the maximum tunnel elevation appears to be approximately el. +8. The base of the tunnel ranges from el.-15'6" (near Discharge Canal) to el. -14'0" (near the Turbine Building) (see below). Note that Discharge Tunnel No. 2 is deeper than Discharge Tunnel No. 1. The depth where Discharge Tunnel No. 2 crosses underneath Discharge Tunnel No. I is el. -16'6". The simplified figure presented below does not show the upward slope of the Intake Tunnel that takes place west of the western limit of the Discharge Tunnel. URS Greiner Woodward-Clyde URS 2-12 Griner ~ WodwardClyde -If~
Please note that the Unit 2 Discharge Tunnel crosses under the Intake Tunnel approximately 40 ft. from the Intake Building. This tunnel was intended to be the discharge tunnel for a second turbine/reactor. Consequently, the tunnel terminates north of the Intake Tunnel rather than connecting to existing Turbine Building. The sketch below shows Tunnel No. 2 passing under the Intake Tunnel. The western limit of Tunnel No. I is where the Discharge Structure joins the Discharge Tunnel.

U e.166\ Approx. 2 ft. concrete Discharge Tunnel No. 2 Foundation Construction: Burns and Roe Dwg. 4035 includes cross-sections of all three tunnels. The sections show that the tunnels are generally constructed of 2 ft thick concrete (see above). All three tunnels include a minimum of one expansion joint. The drawings reviewed as part of this report did not show evidence of a water proofing membrane.
Sumps: No sumps or pits were observed on the Intake and Discharge Tunnel drawings reviewed for this report. Backfill: The intake and discharge tunnels appear to be founded on native soil. The formation at the depth of the base of the Discharge Tunnels would have been the Cohansey Formation. The Upper Clay appears to have been excavated in the area of these structures. There were two cross-sections which indicated the backfill in the area of the tunnels and the Discharge Structure was the same fill as was used in the Reactor and Turbine Buildings (with the exception of a clay layer of variable thickness (1.5 to 3 inches) that abuts the sides of the tunnels). The possible function of this clay layer was not indicated in the construction drawings or the historical reports. Neither was the method of construction or lateral extent. URS GreinerWoodward-Clyde 2-13 UR GeieWodad.lye r~~m ff41-1-o~r ?
Dwg. 40062, "Intake and Turbine Area Excavation and Backfill Plan and Sections," indicates the following:
" The clay backfill layer discussed above is 3 ft thick west of Discharge Tunnel No. 2. " The clay backfill layer thins to 1.5 fit between Discharge Unit No. I and Discharge Unit No. 2. " The clay backfill layer slopes upward east of Discharge Tunnel No. I. " The clay backfill layer along the face (presumed the southern face) of the Intake Structure and Intake/Discharge Tunnels ends at the top ofthe Upper Clay Layer. " The area above the cooling water tunnel was originally backfilled to an elevation of 14' - 6". The backfill slopes upward to approximately el. 23' - 0" at the north-south road that parallels the face of the Turbine Building.
Unresolved issues regarding the backfill in this area include: " The lateral extent of the clay backfill layer; " The purpose of the clay backfill layer;
- The lateral extent of the tunnel excavation to the south and east; and
" The reason for constructing the clay backfill layer. A note on Dwg. 4006-2 stated: "Clay backfill to be placed in 6" max layers and compacted with sheepfoot roller per specs.... and with not less than 4 passes per layer." A note on Dwg. 4029 (Intake Structure Foundation Plan) stated: "After construction flood intake structure to el. -7' 0" prior to shutting of dewatering system. The clay layer, where horizontal, is el. -8' to el. -11' (3 ft thick or el. -8' to el. -8' to el. -6' 6". Combined, this information suggests the clay layer may have been constructed as part of the overall dewatering plan (i.e., to be able to stop dewatering to below el. -7' 6" because of the presence of the clay fill layer. The drawings indicate the presence of the upper clay at the terminus of the clay fill layer. This further supports the speculation that the clay layer is associated with the dewatering plan (i.e., perhaps forming a temporary hydraulic barrier limiting the vertical movement of groundwater). 2.7.2 Discharge Units The pertinent features of the New Radwaste Building are summarized below. URS GreinerWoodward-Clyde 2-14 fort- t, ,,, ,,, , i I .iL9 i3 P
Total Depth: As was stated above, there are two Discharge Units, No. I and No. 2. No. I is functional.

SIMPLIFIED DISCHARGE UNIT CROSS-SECTION (not to scale) approx. finish grade: el. 14' 6" el. -12ackfill 3 ft clay filllayer 1.5 ft clay layer Foundation Construction: The Units were constructed of 2 ft thick steel reinforced concrete. Detail drawings reviewed for this report did not indicate the presence of a waterproofing membrane exclusive oftarpaper at some joints. Tunnels: Discharge Unit No. I connects with the Discharge Tunnel that is discussed in Section 2.8.1. Discharge Unit No. 2 does not connect with a Discharge Tunnel because the second reactor was never built. Sumos: No sumps were observed on the drawings reviewed for this report. Backfill: The base of the Discharge Structures is founded on the Cohansey Formation. There were no drawings or cross-sections that indicated the presence of backfill beneath the Discharge Units. As with the Intake/Discharge Tunnels and the Intake Structure, the clay fill layer is present. The position and thickness of the clay layer is shown in the schematic presented above. Drawing Dwg. 4026 (Circulating Water System Sections and Details Sh. #3) indicated the use of retaining walls during the construction of the discharge units. This indicates that the Discharge Units, unlike the main structures, did not require 1.5 to I or 2 to I excavation slope walls on all sides to maintain the stability of the excavation during construction. Unfortunately, there were no drawings that indicated the location or limits of the retaining walls. 2-15 nowcs\.o.mr.,.,~n,..,e,, 2,2mg, 2PM GreinerWoodward-Clyde URS Greiner Woodward-Clyche 2-15

Foundation Construction: Base slabs were typically 2 ft to 2 ft 6 inches thick. The maximum thickness was 4 ft. Sidewall and ceilings were typically I ft 9 inches to 2 ft thick. Base slab construction appears to have included a waterproof membrane (note: the waterproofing detail referenced on the cross-sections was not included in the drawings reviewed for this report). There was one indication that the 3 layer system (leveling slab, membrane, protective slab) was used on portions of the tunnels. The extent to which this system was implemented could not be determined. It is not unreasonable to assume the three layer waterproofing system, similar to that observed on the major structures where below the water table, was used for the tunnel foundation slab with some modifications for the walls (again where below the water table). There were several references to fiberboard used to protect the walls or roof of the tunnel (presumably during backfilling). It would seem likely that the fiberboard was protective some type of waterproofing system that could be damaged during backfilling if not protected. Sumps: No sumps were noted.

Backfill: The entire ETS was constructed on backfill. The backfill in the Reactor/Turbine Area extends, at a minimum, to el. -14' (also the maximum depth of the Stack). The maximum depth of the ETS is el. 2' 6". Assuming I VAto I sidewall slopes for the excavation of the Reactor Building, the Turbine Building and the Stack, the area of the ETS must have been excavated to a depth greater than el. 2' 6". 2.7.4 Stack The pertinent features of the Stack (Chimney) are summarized below.

The sump directly under the Chimney extends to a depth of-14' 0" Foundation Construction: The octagonal foundation is constructed of 7 ft of steel reinforced concrete. The foundation includes the typical 3 part waterproofing system (leveling slab, waterproof membrane, and protective slab). The waterproofing system may extend around the entire foundation. Tunnels: see discussion of ETS above. Sumos:. As was stated above, a single sump underlies the stack foundation. The sump is 4 ft in diameter, located west of the center of the stack. URS GreinerWoodward-Clyde 2-21 1-OEMý- ý - A13M
Backfill: The foundation for the stack is likely on Cohansey Formation at the base of the sump and backfill under the remainder of the foundation. The Upper Clay has been excavated in this area. 2.7.5 New Radwaste Tunnel The New Radwaste Tunnel goes from the New Radwaste Building to the Old Radwaste Building. The pertinent features of the New Radwaste Tunnel are summarized below. Total Depth: The total depth of the New Radwaste Tunnel where it exits the New Radwaste Building is el. 7' 9". As was previously stated, the tunnel slopes downward towards the Old Radwaste Building. The depth at which it intersects the Old Radwaste Building is unknown because no construction drawings of the tunnel were provided. Foundation Construction: The only foundation information is from the detail sections on the New Radwaste Building drawings. The tunnel is constructed of 3+ ft thick steel reinforced concrete. The base of the tunnel is protected by a 4-inch protective slab, a water proof membrane and a 2-inch leveling slab. The waterproof membranes extends up the sides of the tunnel and was protected by fiberboard before backfilling. The sides of the tunnel are keyed to the top and bottom with 6-inch by 3-inch keys and 6-inch waterstop. Sumps: The sump at the base of the tunnel where it originates was discussed in the section on the New Radwaste Building. There are no tunnel drawings to determine if there are additional sumps along the length of the tunnel or at the tunnel terminus. Backfill: There are no excavation drawings of the New Radwaste Tunnel between the New Radwaste Building and the Old Radwaste Building. If the slope of the tunnel towards the Old Radwaste Building is minimal, the tunnel excavation should not have disturbed the Upper Clay formation. If, however, the tunnel slopes downward and enters the Old Radwaste Building in the deep portion of the building, portions of the Upper Clay would have been excavated. As-built construction drawings and excavation drawings will be evaluated by URSGWC if supplied by GPU. URS Greiner Woodward-Clyde 2-22 , . 1 -w,*-.j13M

SUMMARY
The detailed review of the excavation and construction drawings was intended to I. Determine the depth and, in some cases, the location of subsurface structures that have the potential to release radiologically contaminated material to the soil or groundwater;
- 2. Gather data concerning the construction of these structures (e.g., foundation thickness, presence of water proofing system) to allow GPU to evaluate the potential for construction methodologies to positively or negatively impact the potential for a release.
- 3. Combine construction data with stratigraphic and hydrogeologic data to construct an accurate conceptual site model and 2-dimensional groundwater models.

3.0 STRATIGRAPHY AND HYDROGEOLOGY 3.1 SITE STRATIGRAPHY There are five stratigraphic units found at the Site (exclusive of fill). These include (from shallow to deep): " The Cape May Formation; " The Upper Clay " The Upper Cohansey Formation; " The Lower Clay; and, " The Kirkwood Formation Descriptions of these formations are based on previous reports, principally the "Geotechnical Study, Proposed Radwaste and Off-Gas Buildings" (February 1975), the ."Phase II Report. Ground Water Monitoring System" (March 1984) , and additional boring log review is presented below. Formation thickness data is based on a review of boring logs from within the study area (Table 3-1) and outside the study area (not tabulated). There is limited information on the Lower Clay and the Kirkwood Formations since most borings were terminated in the Cohansey Formation. An additional source of data that could provide a large amount of additional stratigraphic information would be the pre-construction boring program of 1965. A limited amount of this information (three cross-sections) was reviewed. No boring logs were available to corroborate the cross-sections. No geotechnical boring logs from the original construction foundation studies were provided to URSGWC. Without the boring information it is difficult to identify stratigraphic boundaries because descriptors such as color, density, etc. are not available. Projections of stratigraphic boundaries were, therefore, estimated in areas where data was not available. Fill:
== Description:== The fill is a tan, medium to fine grained sand with trace to some silt. No evidence of soft sediment structures such as lenses of silt or coarse sand. The density is URS Greiner Woodward-Clyde UR 3-1Ge~eWodad-lye lW1~OW..~.n, IiJ2USOA
typically less than the Cape May. Based on the excavation pattern discussed above and the description of the fill, it appears likely that much of the fill is excavated Cape May. Thickness: The fill thickness from soil boring logs varies from 0 ft to 38 ft below ground surface (bgs) (el. 23' to el. -15'). The maximum thickness of fill was in the borings closest to the Turbine Building. The maximum fill thickness must be 53 fi (el. -30 vs. surface elevation of +23 ft) in the vicinity of the Reactor Building. This is based on the depth of the excavation for these structures (no boring log was found indicating 53 ft of fill.). Cape May:
Description:
The Cape May Formation is the youngest formation in the Oyster Creek Region. It is described as a light gray to tan medium to fine grained sand with trace to some silt and occasional coarse sand. It is generally poorly compacted. Thickness: The Cape May Formation in the study area varies from 0 ft to 21.5 ft thick. The variation is largely due to the amount of material excavated and replaced by fill as part of the excavation process. The thickness of the Cape May where not excavated is generally in the range of 17 to 20 ft (presuming a ground surface elevation of 23 fi). Upper Clay:
== Description:== The description is as follows: stiff to hard, gray, plastic organic clay containing inclusions (also described as lenses or partings) of dense fine sand with trace to some organic silt. The deposits of fine sand within the Upper Clay layer have high relative densities and are believed to be in the form of lenses or inclusions. Some boring logs describe the "sand lenses" as the dominant feature over a I to 5 ft. thickness. In the area southwest of the Turbine Building, approximately half of the total thickness of the Upper Clay, is silty sand (not clay). Thickness: The Upper Clay is typically on the order of 15 to 18 ft (where not impacted by excavation). Early reports suggest a thinning trend from east to west. This trend is best observed by reviewing information from outside the study area, specifically boring logs from the "West Site" and preliminary data from the Route 9 area. This data suggests the Upper Clay may be as thick as 25 ft east of Route 9 to 0 ft at the "West Site". The lack of a map identifying the locations of these borings makes correlation difficult and URS Greiner Woodward-Clyde 3-2 4. uno-C-..,.,,, Imfd. I, P
very speculative. The suggestion is, however, that there is a thinning trend from east to west but that the Upper Clay is present at 17 ft +/- 3 ft throughout the study area. Alternatively, it is possible that the conclusions drawn by previous investigators are based on a classification of the gray silty sand found in some borings as Upper Cohansey. The conclusion of this study is that the gray silty sand /sandy silt in question is part of the Upper Clay. This conclusion is reflected in the cross-section B-B'. Cohansey Formation:
Description:
Yellow-brown or tan, medium to fine sand with trace to some silt. Also contains pockets of coarse to fine sand, and occasional gravel and pockets of sandy silt. The lower portion of the Cohansey Formation was deposited in a beach or barrier bar environment, while the upper portion is a fluvial deposit. The upper portion can be identified by lower N-values (approximately 45) than the lower Cohansey (approximately 130). Thickness: The thickness of the Cohansey is estimated to be approximately 60-75 ft. There is not enough data to identify a pattern of the thickness of this formation as with the Upper Clay. Lower Clay:
== Description:== The clay is a dense gray medium to fine sand containing a trace to some organic silt and layers or inclusions of very stiff to hard gray organic clay. Thickness: The thickness of the lower clay is on the order of 10 to 20 ft. Again, there is very limited thickness information on this formation. The majority of the boring reviewed for this study terminate well above the Lower clay. Kirkwood Formation:
== Description:== This is a medium to fine sand with trace silt. Casagrande and Casagrande (1968) reported two hard clay layers within the Kirkwood formation at elevations less than -198 ft. Thickness: Unknown in the study area. URS GreinerWoodward-Clyde UR 3-3 renr odwr-Cye un-nIVbSIflP
3.2 CONSTRUCTION IMPACTS TO SITE STRATIGRAPHY This section will describe the impacts of excavation for selected structures on the site stratigraphy, the most noteworthy of which is the removal of the Upper Clay layer which acts as a hydrogeologic aquitard (i.e., a stratigraphic unit that is a partial barrier to hydraulic communication). Included are sketches of the structure depths with the relative depths of the stratigraphic units presented in an accompanying idealized stratigraphic column. This is intended to show the depth of building and the excavation relative to the stratigraphic column. The impacts of the construction on site stratigraphy is demonstrated on the sketches presented below as well as on the following figures: Figure 2-2 Estimated Limits of Excavation for Selected Structures Figure 3-1 Cross-Section A-A' (includes Old Radwaste Building, Reactor Building, Turbine Building and Intake Structure) Cross-Section B-B' (includes New Radwaste and Turbine Buildings) The "sketches" include the construction information from Section 2 and a simplified stratigraphic column that shows the approximate depth of the Upper Clay relative to the excavation and construction of the structure of interest. Reactor Building The Reactor Building excavation extended to approximately el. -30' (53 ft bgs). This excavation resulted in the removal of the entire Cape May, and Upper Clay Formations as well as part of the upper Cohansey Formation. The sketch presented below shows the estimated elevations of the Cape May, Upper Clay, and Cohansey formations relative to the estimated excavation depths. 3-4 Pftwrms~.,oo,2v,,,,.r,,,.,,, 6., 2flfl94 0 P)4 URS GreinerWoodward-Clyde URS Greiner Woodward-Clyde 3-4 'i-n-

Intake Structure The Intake Structure and the accompanying discharge tunnels are shown on the figure below. This figure demonstrates that the Intake Structure (and the tunnels) are founded deeper than the base of the Upper Clay. The concern with these structures is that the lateral extent of the excavations is not clear from the construction drawings (i.e.. there was no as-built drawing that showed whether the excavation was stabilized by a sloped excavation wall or by sheeting or by a combination of construction methods). Also, the as-built cross-sections show a 1.5 ft to 3 ft clay fill layer that was, apparently placed during the backfill of the Intake Structure and Intake/Discharge Tunnel area. This layer was reported tied into the upper portion of the Upper Clay to the east and the lower portion of the Upper Clay to the west. It is believed, however, that the "tie in" to the west could not exist after the Intake/Discharge Canal was constructed since this appears to have resulted in the excavation of the clay. It is also likely that the "tie in" to the east can currently exist because it appears the excavation for the Turbine Building and, possibly the Intake/Discharge Canals resulted in the excavation of the Upper Clay to the east.

It is not known (there are no excavation drawings) if the excavation for the construction of the New Radwaste Building was to the depth of the tunnel sump (el. 3' 6") near the tunnel sump only or if the entire building footprint was excavated to the depth of the tunnel sump. It is suspected that the deep excavation would have been performed only in the tunnel area because this is a relatively small portion of the footprint of the entire building.

New Radwaste Tunnel There is no information on the depth of the New Radwaste Tunnel exclusive of that information included in the discussion of the New Radwaste Building. 3.3 HYDROGEOLOGY 3.3.1 Regional Hydrogeology The following description was presented in the Phase I Groundwater Monitoring Report:
"Both the Cape May and the Cohansey Formations are unconfined aquifers while an artesian aquifer exists in the Kirkwood Formation. The water level in the unconfined aquifer fluctuates seasonally. Occasional thin clay layers in the Cape May and Cohansey formations may cause slightly artesian conditions in localized areas but, in general these two formations communicate hydrologically. Thin clay layers are especially prominent near the coast. A clay layer separates the Kirkwood from the Cohansey. The clay layer acts as a confining layer and artesian heads as high as 22 feet above msl have been found in the Kirkwood (JCP&L, 1972).
Water supplies in the area are derived from wells. These wells are generally 60 to 70 or more feet in depth, penetrating at least one clay boundary to preclude contamination from salt water intrusion or leachate from the many septic tanks in the area. The deeper wells penetrate the Kirkwood aquifer and yield higher quality water. There are also many shallower wells that provide domestic water supplies. On a regional scale, ground water flows generally to the southeast toward the coast, following the trend of the coastal basin sedimentary bedding...." 3.3.2 Site Hydrogeology The site hydrogeology is dominated by two factors: I) the Intake/Discharge Canal; 2) the excavation of the Upper Clay during construction. The excavation of the Upper Clay has resulted in a direct connection between the Cape May and the Cohansey Formations. URS* Greiner Wood/wardl-Clydle 34
East of the Reactor Building the water table is several feet above the Upper Clay. West of the Turbine Building the water table is several feet below the top of the Upper Clay. The construction of the Canal has further contributed to the change in the flow direction of the upper aquifer. Water level in the canal is approximately at sea level (presumed to be el. 0'). Before construction, the water level averaged less than 6 ft below ground surface (approximately el. 20'). Water table levels now average 12 ft below ground surface (approximately el. 12'). This is a result of the change in gradient towards the canal which is at el. 0'. URSGWC has tabulated the stratigraphic and hydrogeologic data collected during previous investigations. The data are tabulated as follows: Table # Name and
Description:
3-1 Summary of Stratigraphic and Hydraulic Conductivity Data: This table includes the stratigraphy and hydraulic conductivity data for former and existing well networks. In instances where data is missing, the boring or well installation log may have been missing of the data was incomplete. 3-2 Additional Hydrogeologic Data: Includes gradient, velocity and dispersivity data from previous work by URSGWC and others. The exact location of all of the data collection points is not known. 3-3 Water Table Elevations: Includes water table elevations and LNAPL thickness (if present). Data is primarily from the area of the diesel fuel spill. The table includes an evaluation of the amount of variation in elevation per well over the rounds of data presented in the table. 3-4 Water Table Elevations: Outer MonitoringNetwork: This is a round of water table elevations from the outer (background) monitoring network. Not all of the locations are shown on Figure 3-2 because some are beyond the area shown in the figure. This data is discussed below. Groundwater elevation data: URSGWC used the groundwater elevation data from the 1982 investigation because no other groundwater elevation data were available that included all of the necessary wells. The data collected quarterly by GPU only includes the wells associated with the diesel URS GreinerWoodward-Clyde 3-9 i '*oF_*Tr *geo4o*vtton*t,*v. a=( 1*4 13*
fuel oil recovery system. This system includes a large number of wells but all are clustered southwest of the area of interest. The background water quality monitoring network is only monitored annually and not at the same time as the quarterly monitoring for the diesel fuel spill. Seasonal Groundwater Elevation Variation: The data reviewed for this report suggest seasonal groundwater elevation variations are generally on the order of 1.5 to 2 ft (Table 3-3). The maximum variation observed was 4.8 ft; however, it could not be determined if this amount of variation was a function of the impacts of the extraction and injection system associated with the diesel fuel remediation system plus seasonal variation. Head Difference between Cape May and Cohansey: Table 3-4 suggests the groundwater elevation in the Cohansey formation is lower than the groundwater elevation in the Cape May. In particular, the water table in wells W-IA and W-2A is significantly lower than any other Cohansey wells. The head difference in these well pairs is on the order of 9 to 10 ft. The head difference in well pairs closer to, but outside of the area in which the Upper Clay was excavated is on the order of 5 to 6 ft. Based on a preliminary review of the survey data for the W-1 and W-2 well pairs it is suspected that there is an error in the survey data. Therefore, until this is resolved URSGWC suggests the data from these pairs is erroneous, GPU has, as part of other site work, re-surveyed these wells. The new data was not available for the preparation of this report. Well Year of Deep or Groundwater Difference Data Shallow Elevation (Shal. -Deep) W-5 1983 Shallow 8.78 W-5/6 Shal.

Higher The instances in which the head difference between the Cape May and the Cohansey Formations is much lower are all in areas in which the Upper Clay has been excavated. This confirms the effectiveness of the Upper Clay as an aquitard. Hydraulic Conductivity: Hydraulic conductivity and other aquifer parameters are tabulated in Tables 3-1 and 3-1. This data will, on an as needed basis, be discussed in Section 4 of this report. 3.4 FRACTURE FLOW ANALYSIS In 1996 Woodward-Clyde prepared a letter report titled: "Groundwater Flow Calculations: Cask Drop Study - Reactor Building." This addressed the hypothetical scenario of dropping a cask of fuel rods onto the slab at the base of the Reactor Buildings. Presumably the cracks would have resulted in a pathway for the entrance of groundwater into the structure. A copy of this letter report is included as Appendix A. Most of the structures included in the current report (including the Reactor Building) are, in part, below the water table (note: in some instances only part of the footprint of the structure is below the water table). We have evaluated the relationship of groundwater elevation to structure depth by applying the analyses used in the Cask Drop Study to all structures. The primary flow mechanisms investigated in the Cask Drop Study were: a) flow through fractures using fractured rock analyses; and, b) "piping" (flow of soil as a viscous liquid through the cracks. The initial study demonstrated that "piping" was not a concern; consequently, we have eliminated the piping calculations from the current analysis as well. The fracture flow analyses are summarized in Tables 3-5 and 3-6. Table 3-5 summarizes the pertinent building data (e.g., slab depth, slab thickness, etc.), groundwater elevation at the building and shows the calculate volume of water required for equilibrium to exist between the aquifer and the building interior (i.e., the water level inside the building URS GreinerWoodward-Clyde 3-I1 LIR GeierWodwrdClde d .it,11P
-lhtS~~4~,,w.
2-
equals the water level outside the building). Using this information, Table 3-6 shows the calculated fracture flow rates for each structure using the formula used in the Cask Drop Study which is presented in Appendix A. The time to reach equilibrium is then calculated by dividing the volume necessary to reach equilibrium by the flow rate (the last row of Table 3-5). Tables 3-5 and 3-6 incorporate the fracture flow formulas presented in Appendix A into an electronic spreadsheet format. URSGWC can provide these tables electronically so that the flow rates and time to equilibrium can be calculated under different conditions (e.g., fewer fractures, high or lower water table, different hydraulic conductivities, etc.). The equilibration times presented are conservative (i.e., biased high) because:
- 1. A high hydraulic conductivity (approximately one order of magnitude higher than the observed average hydraulic conductivity) was used thus generating a higher than expected fracture flow rate;
- 2. A single flow rate was used to estimate the time to equilibration even though the flow rate would decrease as the difference in head between the aquifer and the building interior would decrease as the water level inside the building increased;
- 3. The number (4) and length (42 ft) of the fractures is appropriate to a catastrophic event (i.e., the cask drop scenario) but may be larger than necessary for an "average" release scenario; and,
- 4. The portions of the structures that are below the water table include a water proof membrane below the slab (see Section I) and on the sides of the structures that are at
.or below the water table. This means the event causing the fracture would have had to create not only a breach in the slab but would also have had to breach the integrity of the water proofing system.
The results of the evaluation of ground water elevation vs. foundation elevation and the fracture flow analysis are summarized below.

" Total Volume (gallons): the volume of water necessary to fill the interior of the structure to the same elevation as the surrounding water table or to the top of the structure if the structure (e.g., the Discharge Tunnel) is completely submerged (i.e., bring inside to outside conditions to equilibrium). " Q(flow): the flow rate of water through the fracture in gallons per minute " Time to equilibrate: the amount of time for the water level inside the structure to equal the water level outside the structure (note: if the structure is submerged this is the amount of time to fill the structure). This data demonstrates the potential for releases from most structures of concerns is limited because the groundwater table is above the top of the base slab (the mat). This creates a positive hydraulic head on the slab that would prevent a release from migrating out of the building. The exceptions to the positive head scenario are: I. The New Radwaste Building: This building, as was stated in Section 1, is a slab on grade. The base of the slab is at el. 19'-4". This is above the groundwater elevation of approximately cl. 10'.
- 2. The Old Radwaste Building: This building is partially a slab on grade with shallow grade beams and shallow footings. There is not, consequently, a positive head preventing a release from impacting soil and groundwater for that portion of the building. The central portion of the building is, however, deeper. The calculations presented on Table 3-5 and 3-6 (and above) are for the center section only.

In order to address the potential for releases from the New Radwaste Building and the shallow portions of the Old Radwaste Building, 2-dimensional groundwater flow models have been constructed. These models will be discussed in Section 3. ORS Greiner Woodward-Clyde 3-'14 j - , *,, 0
4.0 TWO-DIMENSIONAL MODELING 4.1 MODEL SELECTED The most universally accepted commercially available numerical groundwater modeling code is MODFLOW, developed in 1988 by Michael G. McDonald and Arlen W. Harbaugh of the United States Geological Survey (USGS). MODFLOW is widely considered to be the industry standard for groundwater flow modeling due to its versatility and ease of application to a variety of groundwater flow problems, including two and three-dimensional flow problems in rectangular as well as radial coordinate systems. MODFLOW is named after its modular program structure, in which different "packages" may be called by the main program to simulate rivers, streams, drains, pumping wells, constant head cells, recharge, and evapotranspiration. A variety of matrix-solving numerical engines may also be called by the main program to perform the finite-difference calculations. MODPATH is the companion particle-tracking code to MODFLOW. MODPATH allows for forward or backward particle tracking of particles in the flow field, as computed using MODFLOW. Particles can be "released" at any location within the saturated zone. Multiple particles can be released in one model run. MODFLOW and MODPATH were selected as the groundwater flow and particle tracking codes to be used for hydrogeologic modeling at the Site because of their ease of use, familiarity to the industry and hydrogeologic community, and applicability to the Site. Applicability was determined by evaluating the goals of GPU and evaluating the ability of MODFLOW and MODPATH to meet those goals. The goals of the modeling phase of this program, as understood by URSGWC were: " Create a two-dimensional hydrogeologic model that included selected structures and calibrate the model using available hydrogeologic data;
- Include modifications to the stratigraphy (excavation of the Upper Clay aquitard) that resulted from the construction of the Reactor Building, the Turbine Building, and other selected structures;
" Evaluate the potential for a theoretical release of a radionuclide to impact downgradient receptors (groundwater and surface water). URS Gremner Woodward-Clyde 4-4-1 .fO1T\.O2=v, 4 rl'I S
MODFLOW and MODPATH were used to create a 2-dimesional hydrogeologic model that:
- 1. Included structures that could potentially impact stratigraphy because of their size and depth;
- 2. Adequately represents the current hydrogeologic conditions based on available data; and,
- 3. Could evaluate the potential migration path of a particle released from a structure of concern (i.e., could a particle released from a building or other structure containing radionuclides impact the canal through a groundwater vector?)?
4.2 MODEL CONSTRUCTION Two separate steady-state groundwater flow models were developed for two separate site vertical cross-sections. The first flow model simulated groundwater flow and particle transport from the Old Radwaste Building along a vertical cross-section through the Old Radwaste Building, the Reactor Building, and the Turbine Building to the Intake Structure and the Discharge Canal, from the east-northeast to the west-southwest along cross-section A-A' (Figure 2-1). The second model simulated groundwater flow and particle transport from the New Radwaste Building along a vertical cross-section through the New Radwaste Building and the Turbine Building to the Discharge Canal, from the north-northeast to the south-southwest along cross-section B-B' (Figure 2-1). Figure 3-1 shows the limits of stratigraphic layers and construction backfill for each cross-section (i.e., geologic cross-sections including major subsurface structures). Both models use the same boundary conditions. One edge of the model is the center of the discharge canal, assumed to be the point of discharge for the Cape May and Cohansey Aquifers at the Site. The other edge of the model is located at a topographic high point, near New Jersey Route 9, assumed to be the location of a local groundwater divide separating groundwater flow to the east towards the Atlantic Ocean from flow to the west towards the discharge canal. The impermeable base of the model is the top of the Lower Clay. The top of the model is the ground surface. Both models consist of 75 twenty-foot wide columns and 30 layers of two-foot and five-foot thicknesses. The models encompass cross-sections 1500 feet long and extending from the ground surface at approximately elevation +23 feet to the bottom of the Cohansey Aquifer at an elevation of approximately -70 feet.

4.3 CALIBRATION Both models were calibrated to the 12/20/83 water table elevations that were measured by Woodward-Clyde and presented in the March 1984 Phase 11 Report, Ground Water MonitoringSystem. Calibration was achieved through varying the recharge and hydraulic conductivity parameters within acceptable ranges until a close match (i.e., within one order of magnitude) was made between the model hydraulic head along the cross-section and the hydraulic head measured on 12/20/83 and interpolated along the cross-section. The following table summarizes the calibrated model hydraulic conductivity: Soil Type Calibrated Model Calibrated Model Horizontal Hydraulic Vertical Hydraulic Conductivity (ft/s) Conductivity (ft/s) Cape May Formation (undisturbed) 6 x 10"' 6 x 10" Backfill I x 10" 1 x 10` Upper Clay 5 x 10` 5 x 10" Cohansey Formation (undisturbed) 7 x 10"' 1 x 10-, Silt at bottom of canal I x l01 I x 10-Hydraulic conductivities used in the model are generally slightly lower than those calculated based on field measurements; however, all values are within the expected range for the type of soils present at the site. Recharge was applied to the top active layer of the model to represent precipitation that migrates through the unsaturated zone to recharge the groundwater. A maximum recharge value of 20 inches per year was assumed to be representative of the Oyster Creek site. This maximum value was applied to the center portions of the models that were not completely paved or covered by structures. For cross-section A-A', a recharge of 20 inches /year was applied to the unpaved area near the canal and to the area east of the Old Radwaste Building. For cross-section B-B', a recharge of 20 inches/year was applied to the area north-northeast of the New Radwaste Building. A reduced recharge value of 15 inches/year was applied to account for portions of the site that are partially paved. For cross-section A-A', this recharge value was applied to the area to the west of the Turbine Building. For cross-section B-B', the 15 inches/year recharge value was applied to the area between the canal and the Turbine Building and the unpaved portions GreinerWoodward-Clyde URS Greiner URS Woodward-Clyde 4-3 4-3 I ,ROWCTSrqOo.2,,,,n,,,, d,~ I - ROMUS'/$ 2ýýon ýo lint.,, HIS. 12iý 1 11]
between the Turbine Building and the New Radwaste Building. Areas of the site that are completely paved or covered by structures were not assigned any recharge. 4.4 RESULTS AND CONCLUSIONS The results of the modeling indicate: I. The Intake/Discharge Canal is the ultimate receptor for groundwater in the Cape May formation and Cohansey Formation in the area of the major structures addressed by this report (Figure 2-1);
- 2. A "particle" released in the groundwater from the areas beneath the Old Radwaste Building and the New Radwaste Building migrates downgradient to the Canal. This means that a discharge impacting groundwater in the are of the New Radwaste Building or the Old Radwaste Building could ultimately impact the canal.
- 3. The depth below grade of the Turbine Building and Reactor Building is not, based on available hydrogeologic data, sufficient to prevent a discharge from the New and Old Radwaste Buildings from reaching the Canal (note: a three dimensional model could indicate a different preferred pathway such as around the sides of the deepest structures).
Both models are based on historic hydrogeologic and stratigraphic data that shows that the construction of the Canal and the excavation associated with the construction of the structures addressed in Sections 2 and 3 has resulted in major changes to the hydrogeologic regime including the localized reversal of the direction of groundwater flow in the Cape May and Cohansey formations. Data collected from the historic hydrogeologic studies conducted before and after the construction of the Reactor and Turbine Buildings support this conceptual model. The particle tracking portion of the modeling did not include potential impacts of solubility, dispersion, advection, adsorption, etc. on contaminant fate and transport. These, and other factors not included in "particle tracking" could result in a reduction of contaminant concentrations to below regulatory guidelines and/practical quantitation limits.

4.5 LIMITATIONS OF MODEL A numerical model attempts to represent continuity in space and time using a set of discrete information. The models assume that hydraulic conditions at the site are static and unvarying in magnitude and direction. It assumes homogeneous and uniform hydraulic and geologic properties of each soil type. The use of a two-dimensional model to represent a three-dimensional system may oversimplify the groundwater flow regime. Certain Site features may not be represented since they are beyond the extent of the two dimensional cross-section. The discretization of the model grid was designed to maximize computational efficiency while providing detail in the model; however, the coarseness of the grid spacing limits the placement and depiction of the model features. Despite these inherent limitations, the two dimensional numerical groundwater flow and particle tracking models calibrate to site conditions and reasonably predict particle movement downgradient in the direction of the canal. 4-5 - - ~M Woodwarcl-Clyde Greiner Woodward-Clyde URS Greiner 4-5 flOSECTfl.OC?.W*.,.
5.0 CONCLUSION
S 5.1 CONSTRUCTION AND STRATIGRAPHY This section summarizes the findings of Sections 2 and 3. 5.1.1 Impacts of Construction on Site Stratigraphy and Hydrogeology The construction of the Reactor Building, Turbine Building, Intake & Discharge Structures, etc. (Sections 2 and 3 of this report) resulted in the excavation of the Upper Clay. the aquitard separating the Cape May Formation from the Cohansey Formation. The construction of the Intake/Discharge Canal also resulted in the excavation of the Upper Clay. The largest impacts of these operations were: " The water table aquifer in the Cape May formation and the underlying Cohansey aquifer are in direct communication in areas in which the Upper Clay has been removed. " The groundwater flow direction of the water table aquifer and, at a minimum the upper portion of the Cohansey have been reversed. The groundwater in both the Cape May and the Cohansey formerly flowed east, towards Bamegat Bay. Groundwater in the vicinity of the plant now flows west towards the Canal. " A groundwater trough (i.e, a depression of the piezometric surface) has been created in areas in which the Upper Clay has been excavated. The elevation of the water table aquifer is now less than the average elevation of the Upper Clay in areas west of Route 9. The sketch shown below demonstrates the change in the water table elevation resulting from the construction of the Canal and the excavation of the Upper Clay.

el. 23' el. 6 el. -14' NOT TO SCALE Groundwater levels in the water table aquifer have, reportedly, dropped several feet in areas between Route 9 and the Canal. Pre-construction water levels in the Cape May formation were higher before the construction of the canal and the main (i.e., deep) buildings. 5.1.2 Construction, Stratigraphy and Release Potential The features of each structure are summarized in tabular format below. The summary includes a qualitative evaluation of the potential for a release of radiological material within the structure to impact soil or groundwater beneath the structure based on data discussed in the previous sections of this report. The qualitative terms used for building release potential are: " Low: high positive groundwater head relative to the top of the base slab of the building; thick slab (>4 ft); waterproofing present; long equilibration time calculated in fracture flow analysis (minimum 10 yrs) " Medium: low but positive head relative to the top of the building; no confirmation of waterproofing present; " Higth: slab above groundwater; slab less than 3 ft thick; no confirmation of waterproofing during slab construction. These "qualitative terms" are to be used only in the context of this report and for this property only based on the data presented in the previous sections of this report. It is important to note that these terms are not intended to be used ad and indication of the potential for actual release. They do not infer the actual site conditions or the presence or absence of release vectors because:
- 1) No foundation inspections were performed (i.e., no fractures were observed)
Gremner Woodward-Ciyde URS Greiner Woodward-Clyde 5-2 5-2 rnorcrs .ON nr, - ly2IflQ, 2n in- ,-
- 2) All fracture flow analyses are "theoretical" and no quantitative fracture data is available;
- 3) It is not known if significant amounts of radiologically hazardous materials are or were stored in areas with the most negative evaluation characteristics (e.g., thin slab, no positive groundwater head, no waterproofing, etc.). The absence the storage of radiologically hazardous material reduces, if not eliminates, release potential; and,
- 4) There were contradictions between "as built" excavation drawings and later soil borings that could not be resolved.
- 5) These terms have no basis in any "regulatory" framework (e.g., NJDEP, NRC, etc.)
The remainder of this section evaluates the structures of concern. In some instances, the buildings or structures of concern have been evaluated separately (e.g., Reactor Building, Turbine Building). In other instances, structures have been evaluated as a group (e.g., the Exhaust Tunnel System). Reactor Buildine Feature Description Total Depth (Abs.

Feature Description resolved because no excavation drawings were available for this structure.. Head on Base of Slab Not applicable. Fracture Flow Analysis Not applicable Release Receptors Soil and Groundwater. Release Potential Medium: Approximately 4 ft of steel reinforced concrete with waterproofing. No head of groundwater preventing release from impacting soil or groundwater Intake Structure and Discharge Structure: These structures do not readily lend themselves to the type of qualitative assessment defined above. Both structures have a positive head on the slab but,
- 1) presumably do not contain material (water) that is radiologically hazardous;
- 2) are, in some fashion, open to the Intake and Discharge Canal and so may not be amenable to the same type of fracture flow analysis as the other structures;
- 3) were not considered potential release structures in GPU's initial scope of work.
These structures were considered significant more for their potential to impact the direction of groundwater flow in the water table aquifer (they extend well below the piezometric surface) and in the evaluation of the area in which the Upper Clay was no longer present (i.e., Is the Upper Clay consistently absent from the Old Radwaste Building to, and including, the Intake and Discharge Canal. The orientation and depth of these structures, as presented on Figures 2-1 and 3-1 may impact the flow path for a potential release if a three-dimensional model is constructed at some future date. Tunnels and Other Structures The tunnel network is more complex than initially anticipated. There are six segments to the Exhaust Tunnel System. Three are shown on the sketch below.

To Old Radwaste u Segment A EXHAUST STACK D ~Segjment B Approximately 68 ft. There are three additional segments leading to the Old Radwaste Building, the Reactor Building and the Turbine Building. In effect, these form a single subsurface structure which includes the area in which the tunnel segments meet and ultimately enter the Exhaust Stack. There are some consistent features of the ETS, regardless of the segment:
" The floor and wall thickness is generally in the are of 2 ft. " The foundation of the tunnels are waterproofed. The walls are also waterproofed but the method of waterproofing could not be determined for all segments. " The tunnels generally slope towards the Exhaust Stack. " The head on the slab is generally low because the tunnels are only partially submerged beneath the water table.
URSGWC calculated the infiltration rate and total time to equilibrium for individual tunnel segments. The average of individual segments is 2.8 years. This calculation presumes that the tunnel segments are distinct and disconnected structures. If, however, the presumption is made that the segments function as a single structure and there is one set of foundation cracks from a single event, the equilibration time is much longer, approximately 17 years. This estimate will increase if the area of the remainder of the ETS structure (stippled pattern) shown in the above sketch exclusive of the tunnels (solid gray color) is included in the calculation of the total are of the ETS. Under this scenario, the estimate to equilibrium is in excess of 25 years. URS GreinerWoodward-Clyde URS Griner 5-6 Wodwarc-Clyde WiT9C2Vp*.efl W i
5.2 TWO DIMENSIONAL MODEL The 2-Dimensional Model (MODFLOW) was used to combine the known information on site stratigraphy and hydrogeology with the construction information (e.g., building depths, excavation extent, etc.) into a single working hydrogeologic model. MODPATH was then used to determine if a contaminant released from a structure of concern could negatively impact groundwater and surface water. The models were not used to evaluate those structures with a positive head on the floor slab. It was assumed that the positive head on the slab would prevent a release from migrating from the inside of the building to the outside of the building. The MODFLOW 2-dimensional models, therefore, accurately reflect the hydrogeologic conditions in the area of the Reactor and Turbine Buildings. This is demonstrated by the fact that an acceptable calibration of the model was achieved and the hydraulic conductivities used for the stratigraphic units are within the acceptable range of variation from the average observed hydraulic conductivities, particularly given the complexity of the sections resulting from multiple subsurface structures and their impact on local stratigraphy. MODPATH confirmed that a discharge impacting groundwater in the are of the New Radwaste Building or the Old Radwaste Building could ultimately impact the canal. Additional contaminant transport and hydrogeologic data is necessary to refine the model. 5.3 DATA GAPS The data gaps identified in this report are as follows: I There is no information regarding the tunnel from the New Radwaste Building to the Old Radwaste Building. 2 There is no excavation as-built for the New Radwaste Building. The depth of the excavation underneath the building could not be determined, 3 The exact nature of the waterproofing could not be determined for all structures. Gaps are discussed in Sections 2 and 3. 4 There are no excavation drawings for the Intake and Exhaust Tunnel. URS Greiner Woodward-Clyde 5-7
5 There is no recent groundwater elevation data that includes enough wells to draw water table aquifer contours across the entire site. The well network exists but is no longer monitored. 6 There is no groundwater elevation data east of the plant. This means the location of the groundwater divide (i.e., water flowing west to the canal vs. water flowing east to Bamegat Bay) could only be estimated. 7 The panicle tracking models demonstrate a release to groundwater east of the Reactor Building could impact the Canal. The particle tracking models cannot evaluate contaminant fate and transport characteristics that could limit the horizontal extent of a theoretical plume (e.g., release volume, release concentration, solubility, dispersion, advection, adsorbtion, etc.). The elimination of these gaps could be used to: a) create a more accurate conceptual model; b) better calibrate the mathematical model; and, c) better determine the potential extent of impact of a contaminant release.

Subject:
Groundwater Flow Calculations: Cask Drop Study - Reactor Building Oyster Creek Nuclear Generating Station Forked River, New Jersey Gentlemen: Woodward-Clyde Consultants (WCC), has completed a groundwater flow and soil piping analysis associated with the hypothetical cracking of the slab of the Reactor Building in the Cask Drop Study for the Oyster Creek Nuclear Generating Station. This letter report is divided into four sections: introduction, groundwater flow, piping flow, and conclusions. Our review of geotechnical considerations is presented in a separate letter-report.
1.0 INTRODUCTION
Under the hypothetical scenario of dropping the cask of fuel rods onto the slab at the base of the Reactor Building, the cracks formed in the slab create a pathway for the entrance of groundwater into the building. Because the slab elevation is below the water table elevation, and because the elevation of water in the building is also below the water table elevation, a positive inward pressure exists through the cracks, resulting in inward flow through the cracks. The conditions causing this inward flow will change only if the water level inside the building becomes equal to or greater than the outside water table elevation. As shown in the following calculations, it would take approximately 8.7 years of water seepage through the cracks for the water level inside the building to reach that state. Should the cracks in the slab form, two separate flow mechanisms will occur. The hydraulic gradient across the slab will induce flow of groundwater through the cracks. This groundwater flow is limited by the hydraulic gradient across the slab, and the flow rate of water through the aquifer, according to the hydraulic conductivity of the geological formation. The groundwater flow rate into the building will gradually diminish over time as the head inside the Reactor Building rises, however it will be a long-term seepage effect. A calculation of the groundwater flow rates through the cracks is presented in Section 2 of this document. Wayne Office P.O. Box 290

April 16, 1996 Woodward-Clyde Page 2 The hydraulic gradient across the slab also will induce stresses in the soil directly below the cracks to a level higher than the strength of the soil. The saturated soil will locally lose all strength and will flow as a viscous liquid through the crack until it reaches an equilibrium. This phenomenon is known as piping, and is expected to be a short-term, relatively small quantity flow. Piping flow is limited by the hydraulic gradient across the crack and the soil friction against the sides of the crack. An approximation of the piping static equilibrium is presented in Section 3 of this document for the purposes of establishing the maximum extent of piping flow. In general, piping effects are estimated to be short-term and minimal in effect, with high soil friction limiting piping to flow within the crack. 2.0 GROUNDWATER FLOW 2.1 Assumptions
- 1. A simplification of the groundwater flow scenario is presented in Figure 1.
- 2. The aquifer at the base of the building is hydraulically connected with the Cape May water table aquifer. (Backfill area around building did not include replacement of upper clay layer following construction.) This assumption is conservative because the Cohansey aquifer has a lower head than the Cape May aquifer. Therefore, by using the head of the Cape May aquifer, a higher gradient exists below the slab. The head in the Cohansey aquifer is higher than the level of water in the building and would not cause outflow if used. Using the head for the Cohansey aquifer would reduce the flow rate into the building.
3
- 3. Material below the building slab is Cohansey sand with hydraulic conductivity K '&lxlO" cm/s. This is conservative since aquifer tests on both aquifers indicate this value is an upper limit of aquifer conductivity.
- 4. The head in the water table aquifer and therefore the head at the base of the slab is 40 feet.
This is a parameter taken from site measurements.
- 5. Water leakage from the cracked torus will result in an initial head inside the building of 5.41 feet. This is a parameter taken from simulation predictions.
- 6. The water in the aquifer will instantaneously fill the 10' thick crack, creating a differential head across the crack of 24.59 feet. Because this analysis is steady-state, this assumption allows the aquifer of water outside the building to become hydraulically connected with the water flowing into the building.

April 16, 1996 Woodward-Clyde Page 3
- 7. Flow into the cracks will not affect the static head of the aquifer. The aquifer is very large in comparison to the size of the cracks and is not expected to experience drawdown. This assumption is conservative because it allows a maximum gradient over time.
- 8. Four cracks are created with width 0.125 inches (= 0.0104 feet) and lengths of 42 feet.
This is a parameter resulting from structural simulations.
- 9. Any piping and running sands have stabilized, and only water flow is taking place. Water flow is a separate process from piping flow and will occur once piping has stabilized.
- 10. A hydraulic flow distance of 40 feet is assumed as a representative flow distance through the aquifer. This is a conservative assumption since it represents a minimum flow path distance from the water table to the base of the building.
2.2 Approach
- Flow through cracks is equivalent to flow though fractured rock using the following formula for hydraulic conductivity of a single fracture (Dominico and Schwartz, p. 87).
- p. gb2 Kf - 12pt where PW = Density of water = 62.37 lbm/ft3 2 g = gravitational acceleration = 32.2 ft/s b fracture width = 0.125 in = 0.0104 ft 2
P 2.359 x 10.5 lbf-sec/fl " Flow through the aquifer is governed by the aquifer hydraulic conductivity. K aquifer hydraulic conductivity = I x 10.3 cm/s = 3.28 x 10-5 ft/s " The hydraulic conductivity controlling flow into the Reactor Building is governed by the aquifer hydraulic conductivity and the fracture hydraulic conductivity according to the following formula: 50feet 40feet 10 feet KT K Kf where KT = the total effective conductivity of the flow regime near a fracture 40 feet = assumed travel distance for flow in aquifer 10 feet = travel distance for flow in fracture LAPROJECMS6E04626\LTh2.DOC / 064I6-96 / wyn
April 16, 1996 Woodward-Clyde Page 4 50 feet = total effective travel distance for flow into the building 0 Flow into the Reactor Building is computed using the following formula: ah Q=KT An-dL where Q total volumetric flow rate A total fracture opening area = 42 feet x 0.0104 feet n number of fractures = 4 dh head drop across the fracture = 30 feet dL length of the fracture = 10 feet 2.3 Computations 0 Fracture hydraulic conductivity is calculated as: 6 2 . 3 7 1bm g lbf (0.0104) 2 pt 2 ft .Ibm. g Kf = p,,12--gb -6

- Because the aquifer hydraulic conductivity is much smaller than the fracture hydraulic conductivity, the aquifer hydraulic conductivity is the controlling factor in calculating the flow into the Reactor Building through the fractures.
- Flow into the Reactor Building is calculated as:
0 = KT A ah = 4.1 x 10- ft/ s.- 42ft. 0.0104ft-4 24.59 ft = 1.76 x 10-4 ft 3 /s = 0.079 gpm

" This volumetric flow rate represents a high flow rate at the initial time of water influx. As the head inside the building increases, the head differential will drop, thus decreasing the flow rate. 1APFLOJECTS6EO4626\LTPLL0Cc 104-16-96 / -p
April 16, 1996 Woodward-Clyde Page 5 2.4 Sensitivity Analysis
- Since fracture flow does not govern the flow regime, aquifer parameters are the only factors that could affect flow calculations.
- If aquifer hydraulic conductivity were 10-2 cm/s instead of 10-3 cm/s, the resulting flow rate would be 0.79 gpm.
- If the water did not fill the cracks instantaneously, the head differential would be 34.59 feet instead of 24.59 feet and the resulting flow rate would be 0.11 gpm.
2.5 Conclusions Even assuming that the flow rate is constant over time, and that the flow rate is as high as 0.79 gpm, it would take approximately 8.7 years to fill the 140' x 140' Reactor Building to the level of the water table. 3.0 PIPING FLOW 3.1 Assumptions
- 1. A simplification of the piping flow scenario is presented in Figure 2.
- 2. The aquifer at the base of the building is hydraulically connected with the Cape May water table aquifer. (Backfill area around building did not include replacement of upper clay layer following construction.) (see section 2.1 for a description of this assumption).
3
- 3. Material below the building slab is Cohansey sand with hydraulic conductivity K = 1x10" cm/s.
- 4. The head in the water table aquifer and therefore the head at the base of the slab is 40 feet.
- 5. Water leakage from the cracked torus will result in an initial head inside the building of 5.41 feet.
- 6. The differential pressure across the slab is 34.6 feet. This is a conservative assumption since in actuality the flow through the crack will only be subject to this initial head differential and will be reduced over time. By using this value it assumes that the soil will be subject to the maximum stresses.

- 7. Flow into the cracks will not affect the static head of the aquifer.
- 8. 4 cracks of width 0.125 inches (= 0.0104 feet) at the top and 6 inches (0.5 feet) at the bottom, with lengths of 42 feet.
- 9. The piped soils are at rest in a static equilibrium. No dynamic effects are considered. This assumption is conservative since additional head losses would occur as a result of dynamic effects.
- 10. A dry density of the soil, p, is taken to be 2.0 g/ml.
- 11. The friction angle for the sand, 4, is taken to be 35 degrees. This is a standard value for sand against concrete.
- 12. The coefficient of earth pressure (lateral pressure) is taken to be Ko = I - sin 4 0.43.
3.2 Approach Assuming that the piped soil is at static equilibrium in the crack, a determination of the height to which the soil would rise inside the building may be made. Using the diagram in Figure 2, the static upwards and downwards forces can be balanced according to the following force balance equation: Fb =W+ Ff where Fb = the upward buoyant force per unit length of the crack W = the weight of the soil in the crack and above the crack per unit length of the crack Ff the downward friction force opposing the upward flow per unit length of the crack 3.3 Calculations In order to determine these forces, a number of definitions are presented: g gravitational constant p = density of water = 1.0 g/ml p = density of the soil = 2.0 g/ml Pb = buoyant density = p, - p 1.0 g/ml 7, = specific gravity of water = pg IAPROJECTSW\E04626\LTR2.DOC 104-16-96 wyn
April16, 1996 Woodward-Clyde Page 7
- specific gravity of the soil = pog = 2y.
Yb = buoyant specific gravity = y. - y. = YW S = friction angle for sand = 350 Ko = lateral pressure coefficient = 1 - sin 4 = 0.43 z = depth of soil inside building to reach static equilibrium Ah = head differential across the crack = 34.6 feet wt width of crack at top of slab = 0.125" = 0.0104' W), width of crack at bottom of slab = 6.0" = 0.5'. h = height of crack = 10 feet 2 A = area of crack interior in cross-section = 2.55 ft
- The static forces may be expressed in terms of the above parameters, according to the following equations:
Fb =y. Ah w, W= y, A, +y,wz Ff =2hCKoY(z+5fi).tanO Substituting in the above force balance equation gives:
- y. Ah wb = y, A, +yw,z +2hCKoyb(z+5fi).tanb Substituting the above values gives:
y 34.6'-0.5'= 2y , 2.55ft2 +2y .0.0104'-z +2.10'-0.43-0.7-5' y, +2.10'-0.43-0.7-z$7 Simplyfing and rearranging gives an expression for z:
-17.9 = 6.04 z z<0 A value for z of less than zero indicates that the friction force is sufficiently strong to prevent any water/soil mixture from moving completely through the crack and into the building under the process of piping. Soil will flow into the crack, but it will not have sufficient buoyant force to push it through the crack to the other side.
3.4 Conclusions The above static analysis for piping flow equlibrium shows that even under the gross assumptions made, with no regard for dynamic effects, the calculated value for the maximum height the soil could reach in the crack as a result of piping is less than the height of the crack.

April 16, 1996 Woodward-Clyde Page 8 Under this conservative scenario, piping will result in a filling Of the crack with sand, after which the sand will stop moving and water will continue to flow through it. 4.0 OVERALL CONCLUSIONS In assessing the overall risk of radionuclide mobilization through the cracks created in the concrete slab under the Reactor Building, neither the piping flow nor the groundwater flow calculations indicate any possible method for water to leave the building under the conditions of positive inflow pressure. It is only after the overly conservative estimated time of 8.7 years, could the head inside the building even potentially reach an equilibrium with the surrounding aquifer, and even then only should the head inside the building rise to a level higher than the surrounding aquifer, could outflow actually occur. In addition, molecular diffusion of dissolved radioactive substances downward through the fractures into the underlying aquifer is not possible while there is a positive inflow pressure. In summary, the findings of the groundwater analysis indicate no risk of radionuclide transport in groundwater out of the Reactor Building in an eight-year period following the cracking of the slab, assuming no further disturbance of the slab and no further hydraulic loading inside the building. Should you have any questions, please do not hesitate to call. Sincerely, Attachments cc: Dr. Stephen C.
