{{#Wiki_filter::;::::=- ENERGYSOLVTIONS Survey Package Worksheet for ARRRC-001 Package Identification No.: ARRR-C00l Prepared by: Paul C. Ely Location: Reactor Building: Inside Bioshield, Floors, Date Prepared: 5/17/2011 Walls and Wood Cover Material Area Classification: Preliminary Class 1 Reviewed By: Area Description This characterization survey includes the area inside the Bioshield. Surfaces include wood & metal flooring (cover) on top on reactor, metal floor inside Bioshield, concrete Bioshield interior walls and top of wood cover material. Historical Information The Bioshield is built over the reactor pool. There is no history of contamination in the area but this area has a higher probability for contamination due to the proximity of the reactor pool and reactor maintenance activities conducted poolside. There is a possibility of activation products due to neutron beams passing into this area during operation. This room is a Class 1 survey unit based on the increased possibility of contaminated and activated materials. Rev. O Page I of4

General Survey Instructions

1. Perform alpha scans at a speed not to exceed 1 detector width per second on 50% of floors on top of reactor (metal and wood cover material) using a 43-37 detector and 20% of wall surfaces using a 43-68 detector.

2. Choose a minimum of 10 measurement locations on floors (on top of Rx and on metal floor inside Bioshield),_§ locations on walls ( on top of Rx and inside Bioshield), and 4 locations on wood cover material (including elevated locations). If elevated areas were identified based on scan measurements, select the location of the highest activity for direct survey measurements. Perform direct alpha surface activity measurements independently at each of the 20 measurement locations for 1 minute each. Note: Due to high gamma background in general area (100 µR/hr and above) beta scans and beta direct measurements do not need to be performed.

3. Note any wall locations that exceed 40 cpm/100 cm2 total alpha activity and determine the extent of the elevated area. Note any floor locations that exceed 50 cpm/100 cm2 total alpha activity and determine the extent of the elevated area.

4. Collect a removable surface activity sample over an area of 100 cm2 in size at 100% of the locations chosen above, plus at judgmental locations at the discretion of the surveyor. A minimum of 20 removable activity measurement locations are required.

5. Perform at least 8 gamma direct survey measurements at 1 cm and at 1 m from the surface or source at locations chosen above. Record readings in µ.R/hr.

6. Prepare survey diagrams of walls, floors and wood cover material, with approximate dimensions and any unique features.

7. Note the locations of direct alpha, smears, and gamma fixed measurements and any samples. A sample of the wood cover material should be taken on the underside. Mark measurement and sample locations in the field using round adhesive backed circular stickers, markers, etc.

8. Record the maximum and average scan results, in cpm, on each wall and floor survey diagram.

9. Record the scan percentages completed for scans on each wall and floor diagram.

Ely Location: Reactor Building: Radioactive Material Date Prepared: 5/10/2011 Storage Room Floors, Walls and Ceiling Area Classification: Preliminary Class l Reviewed By: Area Description This characterization survey includes the surfaces inside the Radioactive Material Storage Room. All surfaces including floor, interior walls and ceiling, plus inventory/surveys of waste stored inside the room. Note: Waste will need to be removed from room before surveys. Historical Information The Radioactive Waste Storage Room (Rm. 45) did not exist in the original building plan but was created at a later time by installing walls and a locked door. There is no history of contamination in the room but it has a higher probability for contamination due to activities in the room. This room is a Class 1 survey unit based on the increased possibility of contaminated and activated materials. General Survey Instructions

1. Perform alpha + beta scans at a speed not to exceed 1 detector width per second on 50% of floors using a 43-37 detector and 20% of wall surfaces using a 43-68 detector. Listen to audible output using headphones, if available.

2. Choose a minimum of 10 measurement locations on floors, 7 locations on walls, and 3 locations on ceilings (including elevated locations). If elevated areas were identified based on scan measurements, select the location of the highest activity for direct survey measurements. Perform direct alpha and direct beta surface activity measurements independently at each of the 20 measurement locations for 1 minute each.

3. Note any wall locations that exceed 40 cpm/100 cm2 total alpha or 450 cpm/100 cm2 total beta activity and determine the extent of the elevated area. Note any floor locations that exceed 50 cpm/100 cm2 total alpha or 1,500 cpm/100 cm2 total beta activity and determine the extent of the elevated area. (The elevated area limits are based on estimated backgrounds of 4 cpm/100 cm2 alpha and 250 cpm/100 cm2 beta on a 43-68 and estimated backgrounds of 15 cpm/100 cm2 alpha and 1,000 cpm/100 cm2 beta on a 43-37.)

4. Collect a removable surface activity sample over an area of 100 cm2 in size at 100% of the locations chosen in step #2, plus at judgmental locations at the discretion of the surveyor. A minimum of 20 removable activity measurement locations are required. Note removable results that exceed 10 dpm/100 cm2 alpha or 200 dpm/100 cm2 beta.

5. Perform a gamma scan survey of surfaces at a speed not to exceed 0.5 meters per second, on 20% of floor and 20% of the wall areas. Perform at least 10 gamma direct survey measurements at 1 cm and at 1 m from surfaces at locations chosen in step #2. Record readings in µR/hr.

6. Prepare survey diagrams of walls, floor and ceiling, with approximate dimensions and any unique features.

7. Inventory all waste items and obtain maximum exposure rate measurements at a distance of 10-cm and I-meter from each waste item for higher exposure rate items. For low exposure rates, obtain 1-cm and l 0-cm readings.

8. Note the location of all waste items on a survey diagram.

9. Note the locations of direct alpha, direct beta, smears, and gamma fixed measurements. Also mark measurement and sample locations in the field using round adhesive backed circular stickers, markers, or equivalent.

10. Record the maximum and average scan results, in cpm, on each wall and floor survey diagram.

11. Record the scan percentages completed for alpha/beta and gamma scans on each wall and floor diagram.

Ely Location: Waste Storage Tanlc Area: Sump Walls and Date Prepared: 5/10/2011 Cover, pad and soil in the area Area Classification: Preliminary Class 1 Reviewed By: Area Description This characterization survey includes the areas inside the waste sump pit that are dry, the Waste Storage Tanlc pads and the ground (soil) surface inside the shielded area beside the Waste Storage Tanks. [The Waste Storage Tanks are covered by another survey package.) Note: The sump pit may be a confined space. Do not place bead or other body parts in the sump pit. Use extensions to lower instrument for readings and to obtain smears. Historical Information The waste sump is used to collect potentially contaminated waste water from operations at ARRR. The waste water is collected in the sump and is pumped into the waste storage tanks for sampling and disposal. There bas been detectible activity in the waste water, but it was below approved release limits for the site. This is a Class 1 survey unit because activity has been detected in the waste water. General Survey Instructions I. Perform alpha + beta scans at a speed not to exceed 1 detector width per second on 50% of pads using a 43-37 detector and 50% of sump wall dry surfaces, if accessible, using a 43-68 detector. See Note above. Use extensions as necessary to reach into sump pit.

2. Choose a minimum of 7 measurement locations on pads and soil, and 3 locations on sump interior walls, if accessible. If elevated areas were identified based on scan measurements, select the location of the highest activity for direct survey measurements. Perform direct alpha and direct beta surface activity measurements independently at each of the 10 measurement locations for 1 minute each.

3. Note any wall locations that exceed 40 cpm/100 cm2 total alpha or 450 cpm/100 cm2 total beta activity and determine the extent of the elevated area. Note any pad or soil locations that exceed 50 cpm/100 cm2 total alpha or 1,500 cpm/ 100 cm2 total beta activity and determine the extent of the elevated area. (The elevated area limits are based on estimated backgrounds of 4 cpm/100 cm2 alpha and 250 cpm/100 cm2 beta on a 43-68 and estimated backgrounds of 15 cpm/100 cm2 alpha and 1,000 cpm/100 cm2 beta on a 43-37.)

4. Collect a removable surface activity sample over an area of 100 cm2 in size at 100% of the locations chosen in step #2 (except soil locations), plus at judgmental locations at the discretion of the surveyor. A minimum of 10 removable activity measurement locations are required. Note removable results that exceed 10 dpm/100 cm2 alpha or 200 dpm/100 cm2 beta.

5. Perform a gamma scan survey of surfaces at a speed not to exceed 0.5 meters per second, on 50% of pad and 50 % of the sump wall dry areas that are accessible. Perform at least 10 gamma direct survey measurements at 1 cm and at 1 m from the surface or equipment at locations chosen in step #2. Record readings in µ.R/hr.

6. Prepare survey diagrams of walls and pads for each area, with approximate dimensions and any unique features.

7. Note the locations of direct alpha, direct beta, smears, and gamma fixed measurements. Also mark measurement and sample locations in the field using round adhesive backed circular stickers, markers, or equivalent.

8. Record the maximum and average scan results, in cpm, on each wall and pad survey diagram.

9. Record the scan percentages completed for alpha/beta and gamma scans on each wall and pad diairram.

ENERGYSOLUTIONS Survey Package Worksheet for ARRRC-005 Package Identification No.: ARRR-C00S Prepared by: Paul C. Ely Location: Bldgl Addition: Counting Roomjand Reactor Bldg: Conf Rm, Control Rm, Employee Locker Rm, GM Date Prepared: 5/10/2011 Office, Machine Shop, Office Supply Rm & South End Radiography Area Classification: Prelimina1y Class 2 Reviewed By: Area Description This characterization survey includes the Counting Room inside the Building 1 Addition, and the Conference/Lunch Room, the Control Room, the Employee Locker Room, the General Managers Office, the Machine Shop, the Office Supply Room and the South End Radiography Area inside the Reactor Building. All surfaces including floor, interior walls and ceilings, and equipment inside the room. Historical Information The Counting Room (9) is used to handle potentially radioactive samples, the Conference/Lunch Room was originally the Chemical Lab, the Control Room is in its original location, the Employee Locker Room was not shown on the original construction drawings but was added soon after construction, the General Managers Office was used as a film processing area before it was moved to its current location. The Machine Shop and the Office Supply Room were created after the Hot Cell was removed and the Machine Shop may at one time have been used to machine activated or contaminated items. The South End Radiography Area was not shown on the original construction drawings but was added after the N-Ray work started. There is no history of contamination in these areas but these areas have a possibility for contamination due to work activities in the area and are therefore Class 2 survey units. Rev. 0 Page I of5

General Survey Instructions

1. Perform alpha + beta scans at a speed not to exceed 1 detector width per second on 50% of floors using a 43-37 detector and 20% of wall surfaces using a 43-68 detector. Listen to audible output using headphones, if available.

2. Note any wall locations that exceed 40 cpm/100 cm2 total alpha or 450 cpm/100 cm2 total beta activity and detennine the extent of the elevated area. Note any floor locations that exceed 50 cpm/100 cm2 total alpha or 1,500 cpm/l 00 cm2 total beta activity and determine the extent of the elevated area. (The elevated area limits are based on estimated backgrounds of 4 cpm/100 cm2 alpha and 250 cpm/100 cm2 beta on a 43-68 and estimated backgrounds of 15 cpm/100 cm2 alpha and 1,000 cpm/100 cm2 beta on a 43-37.)

3. Choose a minimum of 20 measurement locations on floors, 5 locations on walls, and 5 locations on ceilings (including elevated locations). Distribute locations proportionately based on relative sizes of rooms or areas. If elevated areas were identified based on scan measurements, select the location of the highest activity for direct survey measurements. Perform direct alpha and direct beta surface activity measurements independently at each of the 30 measurement locations for 1 minute each.

4. Collect a removable surface activity sample over an area of 100 cm2 in size at 100% of the locations chosen in step #3, plus at judgmental locations at the discretion of the surveyor. A minimum of 30 removable activity measurement locations are required. Note removable results that exceed 10 dpm/100 cm2 alpha or 200 dpm/100 cm2 beta.

5. Perform a gamma scan survey of surfaces and penetrations (if applicable) at a speed not to exceed 0.5 meters per second, on 20% of floor and 20% of the wall areas. Perform at least 10 gamma direct survey measurements at I cm and at I m from the surface or source at locations chosen in step #3. Record readings in µ,R/hr.

6. Prepare survey diagrams of walls, floor and ceiling for each area or room, with approximate dimensions.

7. Note the locations of direct alpha, direct beta, smears, and gamma fixed measurements and all samples. Also mark measurement and sample locations in the field using round adhesive backed circular stickers, markers, etc.

8. Record the maximum and average scan results, in cpm, on each wall and floor survey diagram.

9. Record the scan percentages completed for alpha/beta and gamma scans on each wall and floor diagram.

I Survey Package Worksheet for ARRRC-009 Package Identification No.: ARRR-C009 Prepared by: Steve Croslin Location: Reactor Building - Business Office, Date Prepared: 5/10/201 l Accounting Office, Ladies Room, Men's Room Area Classification: Preliminary Class 3 Reviewed By: Area Description This characterization survey includes the following areas in the Reactor Building: Men's Room, Ladies Room, Business Office and Accounting Office (Rooms 14, 15, 18 & 19). Historical Information Rooms 14 and 15 are the Men's Restroom and the Ladies Restroom, respectively. They appear to have 12-in by 12-in vinyl floor tiles, false ceilings and drains that connect to the city sewer system. Room 18 includes a hallway and the Business Office and Room 19 is the Accounting Office. These offices have floors covered with industrial grade carpet and they both have false ceilings. No records indicating radiological or chemical use or storage were identified. This is a Class 3 survey unit based on a low potential for the presence of contaminated or activated materials. General Survey Instructions

1. Perform alpha + beta scans at a speed not to exceed 1 detector width per second on 20% of floors using a 43-37 detector and 20% of wall surfaces using a 43-68 detector. Listen to audible output using headphones, if available.

2. Choose a minimum of 20 measurement locations on floors and 10 locations on walls (including elevated locations). Distribute locations proportionately based on relative sizes of rooms or areas. If elevated areas were identified based on scan measurements, select the location of the highest activity for direct survey measurements.

Perform direct alpha and direct beta surface activity measurements independently at each of the 30 measurement locations for 1 minute each.

3. Note any wall locations that exceed 40 cpm/ 100 cm2 total alpha or 450 cpm/100 cm2 total beta activity and determine the extent of tl1e elevated area. Note any floor locations that exceed 60 cpm/100 cm2 total alpha or 1,500 cpm/100 cm2 total beta activity and determine the extent of the elevated area. (The elevated area limits are based on estimated backgrounds of 3 cpm/100 cm2 alpha and 340 cpm/100 cm2 beta on a 43-68 and estimated backgrounds of 7 cpm/100 cm2 alpha and 1,330 cpm/100 cm2 beta on a 43-37.)

4. Collect a removable surface activity sample over an area of 100 cm2 in size at 100% of the locations chosen in step #2, plus at judgmental locations at the discretion of the surveyor. A minimum of 30 removable activity measurement locations are required. Note removable results that exceed 10 dpm/100 cm2 alpha or 200 dpm/100 cm2 beta.

5. Perform a gamma scan survey of surfaces and penetrations (if applicable) at a speed not to exceed 0.5 meters per second, on 20% of floor and 20% of the wall areas. Perform at least 30 gamma direct survey measurements at 1 cm and at 1 m from the surface or source at locations chosen in step #2. Record readings in µ,R/hr.

6. Prepare survey diagrams of walls, floor and ceiling for each area or room, with approximate dimensions and any unique features.

7. Note the locations of, direct alpha, direct beta, smears, and gamma fixed measurements and all samples. Also mark measurement and sample locations in the field using round adhesive backed circular stickers, markers, or equivalent.

8. Record the maximum and average scan results, in cpm, on each wall and floor survey diagram.

9. Record the scan percentages completed for alpha/beta and gamma scans on each wall and floor diagram.

Distribute locations proportionately based on relative sizes of rooms or areas. If elevated areas were identified based on scan measurements, select the location of the highest activity for direct survey measurements. Perform direct alpha and direct beta surface activity measurements independently at each of the 30 measurement locations for 1 minute each.

3. Note any wall locations that exceed 40 cpm/100 cm2 total alpha or 450 cpm/100 cm2 total beta activity and determine the extent of the elevated area. Note any floor locations that exceed 60 cpm/100 cm2 total alpha or 1,500 cpm/100 cm2 total beta activity and determine the extent of the elevated area.

4. Collect a removable surface activity sample over an area of 100 cm2 in size at 100% of the locations chosen above, plus at judgmental locations at the discretion of the surveyor. A minimum of 30 removable activity measurement locations are required.

5. Perform a gamma scan survey of surfaces and penetrations (if applicable) at a speed not to exceed 0.5 meters per second, on 20% of floor and 20% of the wall areas. Perform at least 20 gamma direct survey measurements at 1 cm and at 1 m from the surface or source at locations chosen above. Record readings in µR/hr.

6. Prepare survey diagrams of walls and floor for each area or room, with approximate dimensions and any unique features.

7. Note the locations of direct alpha, direct beta, smears, and gamma fixed measurements and all samples. Mark measurement and smear locations in the field using round adhesive backed circular stickers, markers, etc.

8. Record the maximum and average scan results, in cpm, on each wall and floor survey diagram.

Historical Information Rooms 14 and 15 are the Men's Restroom and the Ladies Restroom, respectively. They appear to have 12-in by 12-in vinyl floor tiles, false ceilings and drains that connect to the city sewer system. Room 18 includes a hallway and the Business Office and Room 19 is the Accounting Office. These offices have floors cover~d with industrial grade carpet and they both have false ceilings. No records indicating radiological or chemical use or storage were identified. This is a Class 3 survey unit based on a low potential for the presence of contaminated or activated materials. General Survey Instructions

1. Perform alpha + beta scans at a speed not to exceed 1 detector width per second on 20 % of floors using a 43-37 detector and 20% of wall surfaces using a 43-68 detector. Listen to audible output using headphones, if available.

2. Choose a minimum of 20 measurement locations on floors and 10 locations on walls (including elevated locations). Distribute locations proportionately based on relative sizes of rooms or areas. If elevated areas were identified based on scan measurements, select the location of the highest activity for direct survey measurements.

Perform direct alpha and direct beta surface activity measurements independently at each of the 30 measurement locations for 1 minute each.

3. Note any wall locations that exceed 40 cprn/100 cm2 total alpha or 450 q~rn/100 cm2 total beta activity and determine the extent of the elevated area. Note any floor locations that exceed 60 cprn/100 cm2 total alpha or 1,500 cprn/ 100 cm2 total beta activity and determine the extent of the elevated area. (The elevated area limits are based on estimated backgrounds of 3 cprn/100 cm2 alpha and 340 cprn/100 cm2 beta on a 43-68 and estimated backgrounds of 7 cprn/100 cm2 alpha and 1,330 cprn/100 cm2 beta on a 43-37.)

4. Collect a removable surface activity sample over an area of 100 cm2 in size at 100% of the locations chosen in step #2, plus at judgmental locations at the discretion of the surveyor. A minimum of 30 removable activity measurement locations are required. Note removable results that exceed 10 dprn/100 cm2 alpha or 200 dprn/100 cm2 beta.

5. Perform a gamma scan survey of surfaces and penetrations (if applicable) at a speed not to exceed 0.5 meters per second, on 20% of floor and 20% of the wall areas. Perform at least 30 gamma direct survey measurements at 1 cm and at 1 m from the surface or source at locations chosen in step #2. Record readings in µR/hr.

6. Prepare survey diagrams of walls, floor and ceiling for each area or room, with approximate dimensions and any unique features.

7. Note the locations of, direct alpha, direct beta, smears, and gamma fixed measurements and all samples. Also mark measurement and sample locations in the field using round adhesive backed circular stickers, markers, or equivalent.

8. Record the maximum and average scan results, in cpm, on each wall and floor survey diagram.

9. Record the scan percentages completed for alpha/beta and gamma scans on each wall and floor diagram.

2. ~~a~~~~le~ minimum of 20 measurement locations on floors and 10 locations on walls ~il~including elevated locations). Distribute locations proportionately based on relative sizes of rooms or areas. If elevated areas were identified based on scan measurements, select the location of the highest activity for direct survey measurements. Perform direct alpha and direct beta surface activity measurements independently at each of the 30 measurement locations for 1 minute each.

3. Note any wall locations that exceed 40 cpm/100 cm2 total alpha or 450 cpm/100 cm2 total beta activity and determine the extent of the elevated area. Note any floor locations that exceed 60 cpm/100 cm2 total alpha or 1,500 cpm/100 cm2 total beta activity and determine the extent of the elevated area.

4. Collect a removable surface activity sample over an area of 100 cm2 in size at 100% of the locations chosen above, plus at judgmental locations at the discretion of the surveyor. A minimum of 30 removable activity measurement locations are required.

5. Perform a gamma scan survey of surfaces and penetrations (if applicable) at a speed not to exceed 0.5 meters per second, on 20% of floor and 20 % of the wall areas. Perform at least 20 gamma direct survey measurements at 1 cm and at 1 m from the surface or source at locations chosen above. Record readings in µR/hr.

6. Prepare survey diagrams of walls and floor for each area or room, with approximate dimensions and any unique features.

7. Note the locations of direct alpha, direct beta, smears, and gamma fixed measurements and all samples. Mark measurement and smear locations in the field using round adhesive backed circular stickers, markers, etc.

8. Record the maximum and average scan results, in cpm, on each wall and floor survey diagram.

9. Record the scan percentages completed for alplia/beta and gamma scans on each wall and floor diagram.

Historical Information This survey unit consists of the exterior walls of Demineralizer Building, the Heat Exchanger Building, the Compressor Building, the Maintenance Office and the Chemical Storage Shed (Areas 24, 26, 28, 25, & 46). No releases of radioactive material that would have resulted in contamination of exterior walls were identified in the Historical Site Assessment. This is a Class 3 survey unit based on a low potential for the presence of contaminated or activated materials. General Survey Instructions V

1. Choose a minimum of 20 measurement locations on exterior walls (4-5 on each building). Distribute locations proportionately based on relative sizes of buildings. Perform direct alpha and direct beta surface activity measurements independently at each of the 20 measurement locations for 1 minute each.

2. Note any wall locations that exceed 40 cpm/100 cm2 total alpha or 450 cpm/100 cm2 total beta activity and determine the extent of the elevated area. (The elevated area limits are based on estimated backgrounds of 3 cpm/100 cm2 alpha and 340 cpm/100 cm2 beta on a 43-68) v

3. Collect a removable surface activity sample over an area of 100 cm2 in size at 100% of the locations chosen in step

1. 1, plus at judgmental locations at the discretion of the surveyor. A minimum of 20 removable activity measurement locations are required. Note removable results that exceed 10 dpm/100 cm2 alpha or 200 dpm/100 cm2 beta.

V

4. Perform 20 gamma direct survey measurements at 1 cm and at 1 m from the surface or source at locations chosen in step #1. Record readings in µR/hr.

v

5. Prepare survey diagrams of exterior walls for each building, with approximate dimensions and any unique features.

V Identify exterior walls by side of building (e.g., north side of building).

6. Note the locations of direct alpha, direct beta, smears, and gamma fixed measurements. Also, mark measurement locations in the field using round adhesive backed circular stickers, markers or equivalent.

All accessible interior surfaces are to be surveyed, including floors, interior walls and other surfaces. Historical Information The original Cooling Tower was replaced and is currently referred to as the Backup Cooling Tower. The original tower is approximately 8-ft by 16-ft by 7-ft tall with a painted steel shell, blower on top and redwood vanes on the interior. The newest Cooling Tower, which is routinely used, is approximately 6-ft by 5.5-ft by 8-ft tall with a painted steel shell, a blower on top and galvanized steel packing on the interior. No records indicating radiological use or storage were identified for the cooling towers. This is a Class 3 survey unit based on a low potential for the presence of contaminated or activated materials. General Survey Instructions 1. Perform alpha + beta scans at a speed not to exceed 1 detector width per second on 20 % of total surface area (20% of exterior and interior surfaces and floors, if accessible, on both Cooling Towers) using a 43-68 detector. Listen to audible output using headphones, if available.

2. Choose a minimum of 5 measurement locations on each Cooling Tower (including elevated locations). If elevated areas were identified based on scan measurements, select the location of the highest activity for direct survey measurements. Perform direct alpha and direct beta surface activity measurements independently at each of the :5_

measurement locations for 1 minute each.

3. Note any locations that exceed 40 cpm/100 cm 2 total alpha or 450 cpm/100 cm2 total beta activity and determine the extent of the elevated area. (The elevated area limits are based on estimated backgrounds of 4 cpm/100 cm2 alpha and 250 cpm/100 cm2 beta on a 43-68.)

Survey Package Worksheet for ARRRC-017 Package Identification No.: ARRR-COl 7 Prepared by: Steve Croslin Location: Waste Storage Tanks Date Prepared: 5/13/2011 Area Classification: Preliminary Class 1 Reviewed By: Area Description This characterization survey includes the exterior and accessible interior surfaces of the Waste Storage Tanks (Area 30). Note: The interior of the Waste Storage Tanks may be confined spaces. Do not place any part of the body inside tanks. Use an extension tool to obtain smears and for direct surveys. Historical Information The Waste Storage Tanks are located on the south end of the Reactor Building. There is a larger tank and a smaller tank. The smaller tank is out of service and lying on its side, awaiting repair. The larger tank is upright and standing on a concrete pad. This is a Class 1 survey unit based on the potential for the presence of contaminated or activated materials. General Survey Instructions 1. Perform alpha + beta scans at a speed not to exceed 1 detector width per second on 20 % of total surface area (20% of the exterior and accessible interior surfaces) using a 43-68 detector. Listen to audible output using headphones, if available.

2.

Choose a minimum of 10 measurement locations on the Waste Storage Tanks (including elevated locations). If elevated areas were identified based on scan measurements, select the location of the highest activity for direct survey measurements. Perfonn direct alpha and direct beta surface activity measurements independently at each of the 10 measurement locations for 1 minute each.

3. Note any locations that exceed 40 cpm/100 cm2 total alpha or 450 cpm/100 cm2 total beta activity and determine the extent of the elevated area. (The elevated area limits are based on estimated backgrounds of 4 cpm/100 cm2 alpha and 250 cpm/100 cm2 beta on a 43-68).

4.

1. 2, plus at judgmental locations at the discretion of the surveyor. A minimum of 10 removable activity measurement locations are required. Note removable results that exceed 10 dpm/100 cm2 alpha or 200 dpm/100 cm 2 beta.

5. Perform a gamma scan survey of surfaces and penetrations (if applicable) at a speed not to exceed O.5 meters per second, on 20% of the total area of both Waste Storage Tanks. Perform at least 10 gamma direct survey measurements at 1 cm and at I m from IO surface at locations chosen in step #2. Record readings in µR/hr.

6. Prepare survey diagrams or obtain photos of each Waste Storage Tank, with approximate dimensions and any unique features.

7. Note the locations of direct alpha, direct beta, smears, and gamma fixed measurements. Also, mark measurement and sample locations in the field using round adhesive backed circular stickers, markers, or equivalent.

8. Record the maximum and average scan results, in cpm, on each survey diagram.

9. Record the scan percentages completed for alpha/beta and gamma scans on each survey diagram.
