SECTION I:

SIDE EFFECTS AND MEDICAL STATEMENT DOSAGE AND SIDE EFFECTS PAGE 1 f 1

CAUTION Potassium Iodide should not be used by people allergic to Iodine. Keep out of reach of children. In case of overdose or allergic reaction, contact a physician or public health authority.

DIRECTIONS FOR ADULT USE: One (1) tablet once a day. DO NOT take tablet for more than 10 days.

SIDE EFFECTS:

Usually, side effects occur when people take higher doses for longer periods of time. Do not take more than the recommended dose and do not take dose for longer than the time that is recommended to you. Side effects are unlikely due to low doses over short periods of time. Possible side effects are skin rashes, swelling of salivary glands, and "iodism" (metallic taste, burning of mouth and throat, sore teeth and gums, symptoms of head cold, and sometimes stomach upset and diarrhea). A few people have an allergic reaction with more serious symptoms. These could be fever and joint pains, swelling of parts of the face and body, and severe shortness of breath, requiring immediate medical attention. Taking iodide may rarely cause overactivity of the thyroid gland, underactivity of the thyroid gland, or enlargement of the thyroid gland (goiter).

WHAT TO DO IF SIDE EFFECTS OCCUR:

If side effects are severe or if you have an allergic reaction, stop taking potassium iodide and call a doctor.

• SECTION I I:

Team Leader and Team Member document review of this form by checking the applicable boxes below. respectively.

Check all that apply.

Items 2 through 5 should be answered to the best of your knowledge.

1. have read Section I, "DOSAGE AND SIDE EFFECTS".

2. do not have a known sensitivity to Iodine, nor do have a medical condition that would make me reluctant to take Iodine tablets.

3. have a known sensitivity to Iodine.

4. have a medical condition that may negate my being able to take Kl tablets, e.g ..

hyperthyroidism, hypothyriodism, etc.

5. am currently taking thyroid hormone tablets.

6. am a Declared Pregnant Worker under provisions of, or hereby state my intention to declare pregnancy in accordance with, VPAP-2101, Radiation Protection Program.

9. MISCELLANEOUS GENERAL ASSUMPTIONS:

• Vent Vent: Auxiliary Building, Air Ejector(s). Safeguards (filtered).

Fuel Building (filtered). Containment Purge (filtered). Waste Gas Decay Tank area.

• Process Vent: Waste Gas Decay Tanks, Containment Vacuum.

• Containment leakage: MIDAS uses the higher of the two CHRRMS monitors to calculate the release.

• Air Ejector Monitors: MIDAS adds the Air Ejector release to the associated vent vent release. *

• Main Steam and AFWPT: MIDAS adds the flows from each "open" and "status unknown" valve to calculate the total flow for a particular steam line.

MIDAS sums the releases from all three steam lines and AFWPT to calculate the total release.

• For Vent Vents and Process Vents. MIDAS uses the highest radiation monitor indication on the affected pathway to calculate dose projections. *

• For "Quick Dose" defaults: Unidentified mix. ground level. all release points active. and noble gas and iodine.

• SPS MIDAS FLOW RATES:
