1.0 INTRODUCTION

The Ford Nuclear Reactor (FNR) at the University of Michigan, in Ann Arbor, MI, is being decommissioned.

The decommissioning activities are described in University of Michigan Decommissioning Plan for the Ford Nuclear Reactor; Chapter 4 of that Decommissioning Plan describes the Final Status Survey Plan for demonstrating that the decommissioning has been effective in satisfying Nuclear Regulatory Commission (NRC) criteria for termination of the license and to permit unrestricted future use of the facility.

NRC Default Screening Values have been selected as radiological criteria for the building surfaces and surface soil. Sampling to date has indicated residual concentrations of radionuclides are typically within their respective Default Screening Values.However, there is one small region of subsurface soil, containing concentrations of C-14, potentially slightly greater than the Default Screening Value for C-14 of 11.6 pCi/ g. This location is in the vicinity of the foundation drain around the perimeter of the FNR building.

C-14 has not been identified at other locations in the FNR, and the source of this contaminant is not known. The volume of potentially contaminated subsurface soil is this location is estimated to be less than 50 m 3; for calculation purposes, 50 m 3 was the assumed volume. This document describes the development of a Derived Concentration Guideline Limit (DCGL) for C-14 in subsurface soil associated with the FNR foundation drain.DCGL calculations were based on a dose limit of 25 mrem/y for likely future land use scenarios.

Calculations were performed, based on deterministic analysis, for a time period out to 1000 years, using RESRAD, Version 6.5. The most restrictive DCGL for the various scenarios and time periods was selected for C-14 in the subsurface soil.2.0 SCENARIO DESCRIPTION It is assumed that the University will have institutional control of this site for a period of 100 years, and in the immediate future, after deconammissioning is completed, that the former FNR facility will be used by the University primarily as offices, classrooms, and laboratories.

After the institutional control period ends, the land could be rezoned for industrial, recreational, or residential use. Three scenarios (A-industrial worker on site, B-building occupancy for educational purposes, and C-off-site resident)were considered for current use conditions.

The contamination is limited to a small volume (<50 m 3) of subsurface soil, located beneath approximately 5 m of clean cover and about 4 m above the saturated zone; contaminated soil is at least 500 m from the nearest off-site residential area; and surrounding off-site areas are urban and subsistence farming is not currently a potential land use. The off-site resident scenario was therefore not considered of potential significance and was not evaluated further. Another two scenarios (D- subsistence farming and E- recreational use) were evaluated for the period following institutional control.Scenario A (current on-site industrial worker) assumes that certain outdoor work activities will result in removing clean overburden, exposing the contaminated soil. Workers would perform maintenance and construction operations on the surface of the exposed contaminated soil for a period of 3 months (500 hr/yr or 0.0571 yr), after which the clean overburden would be replaced.

The worker would also be exposed annually for 3 months (0.0571 yr) during renovation activities inside the building.

The 41 June 2012 worker will not ingest contaminated water, plant, fish, meat, or milk obtained from the site. Direct exposure is to an individual, immediately on the other side of the building wall/floor from the contaminated soil, and the calculation assumed uncovered soil. Because radiological decay would result in slightly lower doses for the industrial use scenario after 100 years of institutional control than for the same scenario during the first 100 years, that scenario was not evaluated beyond the 100 year time period.Scenario B (building occupant) assumes presence in the building 2000 hr/yr (0.2283 yr). The occupant would be potentially exposed to external radiation from covered contaminated soil. Exposure to airborne contamination and internal radiation from ingestion of water, plants, meat, milk, and fish, impacted by the contaminated soil are not considered potential exposure pathways.Scenario D (future subsistence farmer) assumes residential use of the site after the institutional control period. The resident farmer would be exposed to direct radiation and to internal radiation from inhalation of contaminated dust, and ingestion of water, plants, meat, milk, and fish and incidental ingestion of soil. All water used by the resident farmer for drinking, irrigation, and household use would be drawn from a deep well, adjacent to the former FNR facility.

Nearby surface water sources and shallow wells are not considered adequate to sustain a subsistence farmer. Two versions of this scenario were considered-one with the clean soil cover in place and one with the clean sol cover removed (intrusion) thus exposing the contaminated soil. Because the intrusion scenario would not occur until after the 100 year institutional control period, intrusion was assumed to occur at the 100 year point and the 1, 3, 10 and 30 year times were considered starting at that point in time. Because of the relatively long half life of C-14 no radiological decay was considered to have occurred prior to discontinuation of institutional control.Scenario E (future recreational use) assumes that an individual camps on the site two weeks per year and engages in recreational activities, such as biking and hiking. During that time drinking water would be drawn from a surface water pond that captures run-off from the site and fish would be obtained from that pond. The recreationist does not ingest plants, meat, or milk obtained from the site.3.0 PATHWAYS AND KEY PARAMETERS Potential radiation doses resulting from multiple exposure pathways are considered in this analysis for all exposure scenarios.

These pathways include: (1) direct exposure to external radiation from contaminated soil material, (2) internal radiation from inhalation of contaminated dust, (3) internal radiation from incidental ingestion of on-site soil, (4) internal radiation from ingestion of plant foods grown in the contaminated area and irrigated with an on-site water source, 42 June 2012 (5) internal radiation from ingestion of meat from livestock raised on site and fed with fodder grown in the contaminated area and irrigated with water drawn from an on-site well or pond (the water ingested by livestock is also drawn from an on-site water source), (6) internal radiation from ingestion of milk from livestock raised onsite and fed with fodder grown in the contaminated area and irrigated with on-site well water or pond water (the water ingested by milk cows is also drawn from on-site water source), (7) internal radiation from ingestion of fish from a pond located down nearby the contaminated area, (8) internal radiation from drinking water from a deep well, (9) internal radiation from drinking water from an on-site water source (pond water), (10) internal radiation from ingestion of plant foods grown off-site and irrigated with contaminated well water, (11) internal radiation from ingestion of meat from livestock raised off-site and fed with fodder grown off-site but irrigated with contaminated well water (the water ingested by livestock is also drawn from a deep well, (12) internal radiation from ingestion of milk from livestock raised off-site and fed with fodder grown off-site but irrigated with contaminated well water (the water ingested by milk cow is also drawn from the well), and (13) ingestion of fish from an off-site surface water source.Table 1 summarizes the applicable exposure pathways for all scenarios and Table 2 lists the key parameters for the applicable exposure pathways.

With exception of dimensions, cover depth, exposure time, and a few scenario-specific parameters, RESRAD Default values have been used for these calculations.

Table 3 contains a list of parameters.

Although they may be listed in Table 3, some parameters are not used in the calculations because the applicable pathway has been suppressed.

CALCULATIONS Printouts of computer runs for the exposure scenarios are attached as an appendix to this report. Dose estimates for I pCi/g (at t = 0) of C-14 soil contamination are summarized in Table 5. Values less than 1E-02 mrem/pCi/g would result in DCGL values greater than 2500 p/ Ci/ g; that value is therefore used as a lower dose bound.Table 4 Annual Dose from 1 pCi/g of C-14 for Evaluated Scenarios Time (yr) Dose (mrem)Industrial Building Subsistence Recreationist Worker* Occupant Farmer 5m Om Cover Cover 0 <1E-02 <1E-02 NA NA NA 1 <1E-02 <1E-02 NA NA NA 3 <1E-02 <1E-02 NA NA NA 10 <1E-02 <1E-02 NA NA NA 30 <1E-02 <1E-02 NA NA NA 100 NA NA <1E-02 <1E-02 <1E-02 300 NA NA <1E-02 <1E-02 <1E-02 1000 NA NA <1E-02 <1E-02 <1E-02* Sum of dose from indoor and outdoor activities Estimated annual dosed from all of the scenarios evaluated were less than 1E-02 mrem/y for a 1 pCi/g concentration of C-14. The concentration of C-14 in subsurface soil would therefore have to exceed 2500 pCi/g to deliver an annual dose of 25 mrem, based on any of these four scenarios..

That concentration is therefore selected as the subsurface soil DCGL for residual C-14 at the FNR site. Criteria for other subsurface soil concentrations of other radionuclides, associated with the former FNR operations, will be the conservative Default Screening Values for surface soil.54 APPENDIX A Printouts of RESRAD Computer Runs 16 RESRAD, Version 6.5 T-s Limit = 30 days 05/04/2012 12:28 Page Summary :JUMC14_rOa_5m File : C:\RESPADFAMILY\RESRAD\6.5\USERFILES\UM\CI4\IWCl4_ROAOM.RAD
