SAMPLING METHODS TO BE USED WHILE PERFORMING ENVIRONMENTAL SURVEILANCE IN

THE VICINITY OF THE BEAVER VALLEY NUCLEAR POWER STATION (BVNPS)

Air samples shall be routinely collected by and shipped to the lab by no later than Tuesday.

Water samples shall be collected and shipped to the lab by the 15th of each month. If samples cannot be collected due to extreme severe weather or other unforeseen circumstances, arrangements shall be made to collect the samples as soon as possible after the scheduled collection date, and an explanation must be noted on the Laboratory Sample Data Sheet.

Chemical preservatives such as hydrochloric acid (HC1) are to be added to some water samples.

Review Material Safety Data Sheet (MSDS) before using such chemicals, and follow the safety precautions outlined. MSDS must be carried by individuals collecting samples when this type of chemical is used or transported.

AIR SAMPLES

Air particulates are collected on 47mm, 0.80µm filter papers, or glass fiber filters. Air iodine is collected in a triethylenediamine (TEDA) impregnated carbon cartridges mounted in tandem with an air particulate filter in a sample holder assembly. The average sampling rate is two to three cubic feet per minute (CFM).

In accordance with established sampling procedures, filter papers and carbon cartridges are changed weekly by ODH contract personnel. Samples are then shipped to the ODH Laboratory located in Reynoldsburg, Ohio for analysis. At the laboratory, gross beta analysis is performed on each filter paper. The weekly filter papers are composited for quarterly gamma isotopic analysis. The carbon cartridges are analyzed for the presence of iodine-131 (I-131).

AIR SAMPLER PROCEDURES

The quick disconnect filter assembly should be loaded and unloaded in the office. This will minimize possible loss of filter paper, or damage to filter by rain, wind, snow, etc.

LOADING THE QUICK DISCONNECT ASSEMBLY

1. Unscrew the top portion of the assembly.

2. Place filter 47mm filter in place.

3. Screw top back on.

4. Unscrew middle section of assembly.

5. Check the seal, which sits under the cartridge to insure it is still intact and not damaged. Notify ODH Bureau of Radiation Protection if a new one is needed.

6. Place carbon cartridge inside assembly making sure the arrow on side of cartridge is facing the direction of the air flow path.

7. Screw sections back together securely so that there is no rattling noise when assembly is shaken.

AIR SAMPLER OPERATION

1. Turn off the sampler pump.

2. Record the running (in hours).

3. Zero the running time meter.

4. Record the flow rate volume for end of the sampling period. (Note: This is also the start reading for the next sample).

5. Remove sample assembly via the quick disconnect and replace with the newly loaded sample assembly.

6. Turn the sampler pump back on.

7. Complete data sheet, to include weekly total volume and running time and unload sample assembly in the office.

UNLOADING THE ASSEMBLY AND SAMPLE SHIPPING

1. When removing the filter papers USE TWEEZERS. The air filter should be handled with care when dust loading is observed because particulate matter is easily removed from the filter invalidating the sample.

2. Place filter paper in 47mm plastic petri slide dish so that the collection side is facing up.

Place lid on petri slide dish and secure with tape. Denote sample location and date collected on petri slide.

3. Remove cartridge, denote sample location and collection date on cartridge and place in sealable baggie and seal.

4. Place prepared petri slides, cartridges and completed white sample data sheet(s) from each location into 12 x 15 Tyvek envelope.

5. Remove paper from quick strip closure and seal the envelope.

SURFACE WATER SAMPLES

A one-gallon and a two-liter grab samples of untreated water are to be collected by the 15th of each month from the raw water intake at the East Liverpool Water Treatment Plant which draws water from the Ohio River. The one-gallon sample is collected in a cubitainer to which 5 milliliters of hydrochloric acid (HC1) is added*; and the two-liter sample is collected in a container to which no hydrochloric acid is added. Both samples are shipped on the collection day to the Laboratory in Reynoldsburg, Ohio, for analyses. Gross beta and gamma isotopic analyses are performed on each of the monthly water samples, and tritium analysis is performed on the quarterly composites of the monthly samples.

BVNPS operates a continuous water-sampling device at this location. Although ODH and BVNPS personnel sample water from the same point, the sample collection is independent and not split.

* Transfer 5 milliliters of hydrochloric acid to the one-gallon cubitainer using a pipette and pipette bulb. NEVER PIPETTE BY MOUTH.

SHIPPING INSTRUCTIONS FOR ALL SAMPLES

1. Ship sample(s) with copy of lab order to Bureau of Public Health Laboratory at:

Bureau of Public Health Laboratories Radiochemistry Section 8995 E. Main St., Bld 22 Reynoldsburg, OH 43068
