UVAP Continuing Characterization:
Pond Sediment Summary A pond, covering a surface area of approximately 1600 m2 and ranging in depth from approximately 2 to 4 m, is located just to the south of the University of Virginia Reactor Facility.
During Reactor Facility operation this pond received discharges from certain laboratory drains, floor drains, and other sources of non-sanitary wastewater from the building. Run off from the adjacent land areas drain directly into this pond; an overflow from the nearby storm drain also empties into the pond.
The pond was drained to expose and permit the sediments to dry for improved access and to
.facilitate radiological monitoring and sediment sampling. Thickness of sediments varied from a fraction of a meter to 2 meters depending on location.
Survey grid corners were marked, dividing the pond into 10-meter square sections and referenced to the centerline of the dam spillway. Sections containing greater than 25% pond surface were numbered I thru 22, starting in the southeastern corner section (Figure 1). Surface gamma scans were initially performed in each 10-meter square section to identify locations of elevated direct radiation. The results were logged per 1.5-meter wide lanes with the highest to lowest noted readings.
See attached survey UVAP-0245. Any discemable localized increase readings were denoted on the map and physically flagged for bias sampling.
Gamma scans of the drainage stream from the pond were performed for approximately 20 m below the spillway release point. Samples of sediment were obtained at 3 locations considered representative of the average stream conditions.
Samples were obtained from 16 statistical sample points and 18 biased sample locations (Figure 1).
A 2-inch diameter bucket auger and 2-inch PVC piping was used to collect samples. Continuous sampling was performed from surface to 6 inches beyond the interface of sediment/original soil or to auger refusal, whichever occurred first. Samples were placed in plastic bags or jars with each sample representing 6-12 inches of sediment depth. To the extent possible, a plastic sleeve was utilized to maintain an open sampling hole. Sampling tools were cleaned and surveyed for contamination, following each sample collection.
Samples of the pond sediments were screened by the on site gamma spectroscopy system, and ranged from 0.3 pCi/g to 4.0 pCi/g Cs-137. One sample indicated Co-60 at 1.6 pCi/g. Results are shown in Table 1.
Background sediment samples were obtained from the nearby Ragged Mountain Reservoir, upstream on the drainage feeding into the pond, and the soft rock face and fill dirt in the upper parking area. They were screened by the on site gamma spectroscopy system and results are shown in Table 2.
Samples from the UVAR pond, UVAR drainage and Ragged Mountain Reservoir were scanned for indication of increased direct gamma levels. Boreholes were gamma logged initially at 6",
then at 12" intervals to the borehole bottom. Some locations did require insertion of a sealed tube to maintain the borehole open during gamna logging.
Based on the on site gamma screening, gamma logging and direct beta readings, six of the highest activity samples were sent to the off site laboratory for analysis. Gamma spectroscopy and 10 CFR Part 61 analyses for transuranics, Sr-90, and other hard-to-detect radionuclides were performed.
Results ranged from 2.08 pCi/g to 3.46 pCi/g for Cs-137, no detectable Co-60 above MDC' level, 1.29 pCilg to 3.61 pCi/g Ra-226, 2.42pCi/g to 4.77pCi/g Th-232, and Pu-241 at 15.8pCi/g. Results are shown in Table 3.

UVAP Continuing Characterization:
Pond Sediment Summary Two background samples were also submitted to the off-site laboratory for analysis. Results are shown in Table 4.
The remaining unanalyzed samples (those not sent to the offsite laboratory) were retained and stored under chain of custody.
Based on the results of off site laboratory analyses, surface measurements, and gamma borehole logs, the levels and ratios of facility-derived contaminants were determined and no areas in the pond were identified to require remediation. This survey satisfies the continuing characterization requirements of Area 13 and 14 from the characterization report, Appendix A of the University of Virginia Reactor Decommissioning Plan.

UVAP Continuing Characterization:
Mezzanine Crawl Space Summary The Mezzanine Crawl Space is located on the mezzanine level of the UVAR facility. Access to the area is located in the main stairwelL The room is classified as a class 2 area with approximately 100-n 2 surface area. The room contains concrete block walls, precast concrete panel ceiling with steel support beams and a dirt floor.
A reference Grid system was -used for this survey. The grid was set at 1-meter intervals with the grid starting location being the southwest corner of the room.

- 1. Surface Scan Surveys Scans of wall, overhead and other surfaces were performed using a Ludlum Model 43-68 handheld 125 cm 2 gas proportional detector with a Ludlum Model 2221 ratemeter/scaler. Scanning was accomplished by moving the detector over the surface at a speed of approximately 10 cm per second (approximately 4 inches per second). The distance between the detector and the surface was maintained at a practical minimum, consistent with surface conditions.
Gamma scans were performed using a Ludlum Model 44-10 handheld sodium iodide detector with a Ludlum Model 2221 ratemeter/scaler. The scan was performed by moving the detector in a serpentine pattern, while advancing at a speed of approximately 0.5 m per second. The distance between the detector and surface was maintained within 5 cm.
The count rate was monitored by means of the audible signal output, and when an increase in instrument response above the ambient level was noted, the surveyor paused for several seconds to confirm the conditions. The observed lowest to highest range was recorded on the associated survey map. Two slightly elevated reading were noted during the scan of the dirt floor and marked for soil sampling. No other increases were noted above ambient levels during all other scan. See attached surveys UVAP-0570, 0573 and 0574
- 2. Integrated Direct Surface Beta Radioactivity Measurements Measurements of surface alpha-plus-beta radioactivity was performed using a Ludlum Model 43-68 handheld 125 cm gas proportional detector coupled to a Ludlum Model 2221 ratemeter/scaler. The expected alpha activity is minimal, <10% and all detected counts are considered to from beta activity. Counts were integrated for a one-minute counting interval. Two measurements were performed. The first was a surface measurement, performed in the typical manner (i.e., with the detector face uncovered); this measurement included contributions from beta particles emitted from the surface and interactions of ambient gamma photons with the detector. The second measurement was performed at the same location with the detector face covered by a layer of wood approximately 1.27 cm (l2-inch thick). The detector response for this second measurement is representative of the contribution from gamma radiation only. The difference between measurements with an uncovered (unshielded) detector and covered (shielded) detector represents the level of beta activity. Measurements were performed at elevated locations as 5/19/03
UVAP Continuing Characterization:
Mezzanine Crawl Space Summary identified by scans and at locations representative of the general surface area. Results for these static readings ranged from 286 dpm/lOOcm 2 to 2195 dpm/l OOcm 2 .
- 3. Smear Sample Collection and Analysis Smear samples for removable activity were collected by wiping a 5 cm (2-inch) diameter cloth disc over approximately 100 cm 2 (15.5 in2 ) areas of the surface, while applying moderate pressure. Smear samples were obtained at each location of direct surface activity measurement. Smear samples were counted for alpha and beta radioactivity on a Tennelec automatic gas proportional counter. All smear results were less than MDA for beta (22.99 dpmflOOcm 2 ) and alpha (19.04 dpm/lOOcm 2 ).
- 4. Volumetric Sample Collection and Analysis Soil samples were obtained by hand auguring, at 9 locations in the dirt floor, 0 to 6-inches in depth. Samples were submitted for on site gamma isotopic analyses. No facility related activity was detected. The samples were placed on a chain of custody and stored onsite. See Table 1 for results.
- 5. Conclusions Based on results of these surveys, no remediation is required. The mezzanine crawl space is ready for Final Status Survey.

UVAP Continuing Characterization:
Reactor Plant Stack Summary The University of Virginia Reactor (UVAR) Facility plant stack is located on the east side of the Reactor Confinement Building. The plant stack is 58-feet in total height running from the Mezzanine floor to 4-feet above the Confmement Building. The plant stack is made out of red brick and contains two duct liners; one 14-inch diameter made of transite and one 8-inch diameter made of terracotta. The 14-inch duct is the exhaust from the fume hoods in room M019, the hot cell, the beam port closures, and the bulk access facility. The 8-inch duct is the exhaust flue from the boiler and was replaced in approximately 1992 with a new metal duct running along the outside of the plant stack.
The plant stack also contains the air inlet and exhaust ducting to the reactor room.
The Characterization survey included the 14-inch duct, 8-inch duct, reactor room exhaust inlet, and top plenum area. A flue brush was used to obtain a volumetric sample from the interior of the 8-inch flue running the length of the plant stack. The HEPA filter and associated ducting, inline from the hot laboratory Room M019 fume hoods exhaust, was removed and discarded.
Co-60 has been determined to be the major facility related contaminant. The Decommissioning Plan provides a Derived Concentration Guideline Level (DCGL) of 7100 dpm/lOOcm 2 total activity and 710 dpm/lOOcm 2 removable activity for CO-60.
- 1. Surface Scan Surveys Scans of surfaces at the inlet and exhaust of the each flue, reactor room exhaust inlet, and plenum area were performed using a Ludlum Model 43-68 handheld 125 cm2 gas proportional detector with a Ludlum Model 2221 ratemeter/scaler. Scanning was accomplished by moving the detector over the surface at a speed of approximately 10 cm per second (approximately 4 inches per second). The distance between the detector and the surface was maintained at a practical minimum, consistent with surface conditions.
Gamma scans were performed using a Ludlum Model 44-10 handheld sodium iodide detector with a Ludlum Model 2221 ratemeter/scaler. The scan was performed by moving the detector in a serpentine pattern, while advancing at a speed of approximately 0.5 m per second. The distance between the detector and surface was maintained within 5 cm.
The count rate was monitored by means of the audible signal output, and when an increase in instrument response above the ambient level was noted, the surveyor paused for several seconds to confirm the conditions and marked the location for activity determination by static count. The observed lowest to highest range was recorded on the associated survey map. See survey UVAP-0400 and UVAP-0571.
The beta/alpha scans ranged from 263 cpm to 982 cpm. The gamma scans ranged from 7400 cpm to 17,800 cpm.
- 2. Integrated Direct Surface Beta Radioactivity Measurements Measurements of surface alpha-plus-beta radioactivity was performed using a Ludlum Model 43-68 handheld 125 cm 2 gas proportional detector coupled to a Ludlum Model 2221 ratemeter/scaler. The expected alpha activity is minimal, <10% and all 5/19/03
UVAP Continuing Characterization:
Reactor Plant Stack Summary detected counts are considered to from beta activity. Counts were integrated for a one-minute counting interval. Two measurements were performed. The first was a surface measurement, performed in the typical manner (i.e., with the detector face uncovered); this measurement included contributions from beta particles emitted from the surface and interactions of ambient gamma photQns with the detector. The second measurement was performed at the same location with the detector face covered by a layer of wood approximately 1.27 cm (l 2-inch thick). The detector response for this second measurement is representative of the contribution from gamma radiation only. The difference between measurements with an uncovered (unshielded) detector and covered (shielded) detector represents the level of beta activity. Measurements were performed at elevated locations as identified by scans and at locations representative of the general surface area. Direct integrated readings ranged from 136 dpm/lOOcm 2 to 3146 dpmllOOcm 2 .
- 3. Smear Sample Collection and Analysis Smear samples for removable activity were collected by wiping a 5 cm (2-inch) diameter cloth disc over approximately 100 cm2 (15.5 in2) areas of the surface, while applying moderate pressure. Smear samples were obtained at each location of direct surface activity measurement. Smear samples were counted for alpha and beta radioactivity on a Tennelec automatic gas proportional counter. Smear sample activity ranged from <MDA (22.99 dpm/lOOcm 2) to 124 dpm/lOOcm 2 .
- 4. Ducting Survey A volumetric sample was obtained utilizing a cleaning brush pulled through the 8-inch boiler flue. Svabs were obtained from the inlet and outlets of both the 8 and 14-inch ducts. These samples were submitted for on site gamma isotopic analyses. Results from the swab obtained from the top of the 14-inch duct indicated the presence of U-238 at detectable levels. All other samples indicated no reactor facility related isotopes. Gamma spectroscopy reports are attached. Samples were managed under chain-of-custody procedures and stored for additional counting or offsite analysis.
- 5. Conclusions Static surveys and the volumetric sample did not indicate facility related activity above the DCGL. Based on results of these surveys, no remediation is required. The plant stack and associated ventilation is ready for Final Status Survey. This survey satisfies the continuing characterization requirements of Area 3 from the characterization report, Appendix A of the University of Virginia Reactor Decommissioning Plan.
