Tab 3 EP-PS-247-3 Field Monitorinq Stratecv Notes 1.0 Dispatching of Field Teams 1.1 If OSCAR was not activated prior to your arrival at the EOF, activate OSCAR as soon as possible. Upon activation it will take up to 30 minutes for OSCAR to complete equipment checks and clear the South Gatehouse.
Note: When the OSCAR Iodine sampling equipment Is being source checked, RMS will alarm. Reset OSCAR Iodine channel on RMS by selecting the OSCAR Iodine channel and using [ALTJ[C] to reset the channel. Resetting the OSCAR gamma and particulate channels may also be desirable after OSCAR exits the South Gatehouse. That Is accomplished by selecting each of those channels and using [ALTJ[C] to reset each channel.
1.2 The ALPHA and BRAVO field teams should usually be deployed expeditiously upon activation of the EOF, even if a radioactive release has not yet occurred.
(One or both of these teams may be dispatched from the TSC prior to EOF activation.) In such cases the teams may be used to confirm the existence of background dose rates (EDE) in the areas surrounding SSES.
Note: Consider plume location when deploying these teams.
2.0 Field Team Monitoring Strategy - RMS is Available 2.1 Initially, all deployed Field Teams are to be used to traverse the potentially affected sectors to locate the plume and its centerline.
2.2. Once the plume is located and the affected sectors are identified:
2.2.1 OSCAR will be used to characterize/quantify the release by traversing the affected sector(s).
2.2.2 ALPHA and BRAVO field teams will then be used to track the plume direction and movement by monitoring the plume boundaries within the 10-mile EPZ. As conditions warrant, these teams may also be used to characterize plume centerline conditions.
2.2.3 At least one field team (ALPHA or BRAVO) should be kept on the east side of the Susquehanna River to facilitate coverage of the EPZ.
2.3 Once the plume has been characterized and the source of the release has been isolated, consult with the DAST and DASU to determine an appropriate reduction in plume traverse frequency and designate a low dose waiting area for OSCAR.
EP-AD-000-085, Revision 1, Page 1 of 3
Tab 3 EP-PS-247-3 3.0 Field Team Monitoring Strategy - RMS is Inoperable 3.1 Initially, all deployed field teams are to be used to traverse the potentially affected sectors to locate the plume and its centerline.
3.2 Once the plume is located and the affected sectors are identified:
3.2.1 OSCAR will be used to characterize/quantify the release by traversing the affected sector(s). As conditions warrant, OSCAR shall obtain a manual air sample at the highest reading location inside the plume.
3.2.2 ALPHA and BRAVO field teams will then be used to track the plume direction and movement by monitoring the plume boundaries within the 10-mile EPZ. As conditions warrant, these teams may also be used to characterize plume centerline conditions.
3.2.3 At least one field team (ALPHA or BRAVO) should be kept on the east side of the Susquehanna River to facilitate coverage of the EPZ.
3.3 Once the plume has been characterized and the source of the release has been isolated, consult with the DAST and DASU to determine an appropriate reduction in plume traverse frequency and designate a low dose waiting area for OSCAR.
4.0 Terrain Factors to Consider when Deploying Field Teams 4.1 Winds from the S sector could result in a significant backwash effect. This type of terrain-induced backwash could occur in the hills immediately north of SSES and at a number of other locations within several miles of the plant. High external dose rates and surface contamination levels characterize these backwash effects.
4.2 Winds from the S, SSW, SW, WSW, or W sectors can also result in:
4.2.1 The plume remaining within the river valley.
4.2.2 The plume traveling up Wapwallopen gorge, east of SSES.
4.3 Winds from the NNE, NE, ENE, E, ESE, SE, or SSE can result in the entrainment of the release in the updraft of the operating cooling tower(s). In this case, evaluate the use of upper level wind sensor information when determining field team placement.
4.4 Be aware that the plume may travel much faster than is indicated by the on-site wind speeds, particularly when the plume is traveling along the river valley.
4.5 Be aware that the complex terrain south and southeast of the plant and on the east side of the Susquehanna River has a negative effect on the accuracy of a MIDAS projection of the plume's location.
EP-AD-000-085, Revision 1, Page 2 of 3
Tab 3 EP-PS-247-3 In general, the further from the plant you get, the less reliable a MIDAS prediction will be on the plume's location.
5.0 Exposure Control Notes 5.1 Review the exposure control statements of RWP #8002 (E-Plan: Field Monitor Activities) and/or RWP #8001 (E-Plan: OSCAR Activities), as applicable.
5.2 Notify the DAST/DASU promptly when the field teams report any of the following conditions:
- Dose Rates > 1,000 mrem/hr
- Cartridge Readings > 1,200 cpm 5.3 Notify the DAST or DASU immediately if YTD exposure plus current SRD readings are within 200 mrem of a teem member's applicable dose limit and immediately position that team in a low background area. Do not send this team back into the plume without the direction of the DAST or DASU.
5.4 Initiate tracking of CDE Iodine and TEDE via the Calculation and Tracking Sheet for Estimated Iodine CDE and TEDE Doses form in Tab 7 of EP-PS-247 when:
- When directed by the DAST/DASU.

Tab 5 EP-PS-247-5 PPL EMERGENCY PERSONNEL DOSE ASSESSMENT AND PROTECTIVE ACTION RECOMMENDATION (PAR) GUIDE CHECK 0 1.0 Limits for EMERGENCY doses.
D 1.1 An EMERGENCY DOSE AUTHORIZATION (see EMERGENCY EXPOSURE EXTENSIONS) may be granted in order to protect facilities, and or equipment to substantially limit the escape of radioactive effluents or control fires. The maximum planned doses are:
1.1.1 Whole body (TEDE)(') dose shall not exceed 10 rem.
1.1.2 Dose to any organ (CDE)(2), including the skin and extremity (SDE)(3), shall not exceed 100 rem.
1.1.3 Dose to the lens of the eye shall not exceed 30 rem (LDE)(4).
o 1.2 An EMERGENCY dose authorization may be granted for life-saving actions or protection of large populations. The maximum doses are:
1.2.1 Planned whole body (TEDE)( 1 ) doses shall not exceed 25. rem.
1.2.2 Planned dose to any organ (CDE)( 2), including skin and extremity doses, shall not exceed 250 rem.
1.2.3 Dose to the lens of the eye shall not exceed 75 rem (LDE)(4).
1.3 RARE situations may occur in which a dose GREATER THAN those specified in SECTION 1.2 above for emergency dose would be unavoidable to carry out a lifesaving operation or to avoid extensive exposure of large populations. It is not possible to prejudge the risk that one should be allowed to take to save lives of others, therefore no upper limit has been established.
(1) The sum of the Effective Dose Equivalent resulting from the exposure to external sources and the Committed Effective Dose Equivalent incurred from all significant inhalation pathways during the early phase.
(2) The Committed Dose Equivalent to the thyroid from radioiodine.
Shallow Dose Equivalent.
(4) Lens Dose Equivalent.

Tab 5 EP-PS-247-5 PPL EMERGENCY PERSONNEL DOSE ASSESSMENT AND PROTECTIVE ACTION RECOMMENDATION (PAR) GUIDE CHECK0 2.0 For any EMERGENCY EXPOSURE OR ACCIDENTAL OVEREXPOSURE, the assessment actions in step 2 of the EMERGENCY EXPOSURE EXTENSIONS must be performed.
3.0 PROTECTIVE ACTIONS Q 3.1 Potassium Iodide 3.1.1 For thyroid doses that are strongly expected to exceed 10 rem (CDE) (2), ingestion of a KI dose of 130 mg (100mg - iodine) should be recommended, except as noted in paragraph 3.1.2, to personnel whose emergency assignment or qualifications do not allow other protective measures to be taken (e.g. respiratory protection, evacuation, relocation, etc.) to maintain the dose to the thyroid at less than 10 rem.
NOTE: HHS/FDA guidance is that adults over 40 years of age need take KI only in the case of a projected large internal radiation dose to the thyroid ( > 500 rem) to prevent hypothyroidism; the guidance is 10 rem for adults over age. 18 to age 40.
3.1.2 KI should not be administered to any emergency worker who:
- a. does not concur with its use, or
- c. has been directed by their Physician or Pharmacist to avoid ingestion of iodine and/or foods containing iodine such as shellfish.
(2) The Committed Dose Equivalent to the thyroid from radioiodine.
EP-AD-000-125, Revision 9, Page 3 of 13
Tab 5 EP-PS-247-5 PPL EMERGENCY PERSONNEL DOSE ASSESSMENT AND PROTECTIVE ACTION RECOMMENDATION (PAR) GUIDE CHECK0 3.1.3 Onsite issuance of KI for iodine prophylaxis requires the approval of the EMERGENCY DIRECTOR. Issuance to EOF and FIELD EMERGENCY MONITORING/SAMPLING TEAM personnel requires the approval of the RECOVERY MANAGER when the EOF has relieved the TSC of emergency management activities.
The EMERGENCY DIRECTOR will approve issuance prior to that time. These approvals must be documented on the POTASSIUM IODIDE (KI) TRACKING FORM.
3.1.4 Unless the EMERGENCY DIRECTOR or RECOVERY MANAGER instructs personnel to do otherwise, the RItablets should generally be taken as soon as possible after thyroid dose exceeding 10 rem CDE (2)is projected.
NOTE: Stable iodine (KI) is most effective when administered immediately prior to exposure to radioiodine. Significant blockage of the thyroid dose can be provided by administration within a few hours after uptake of radioiodine.
3.15 In the event a significant exposure to the thyroid is projected to continue over a period of several days the CONSULTING RADIOLOGICAL PHYSICIAN should be requested to provide a recommended KI dosage for subsequent KI usage. (See Emergency Telephone Directory for telephone number.)
3.16 Until input/advice from the CONSULTING RADIOLOGICAL PHYSICIAN is available, a quarter of a tablet should be taken on days of exposure that follow the day on which the initial full tablet dose (130 mg) was taken.
3.17 If a worker expresses concern with the use of KI and/or is unsure if it will interact with his/her current medication,
- a. the CONSULTING RADIOLOGICAL PHYSICIAN should be requested to provide input/advice to the individual concerning the administration and cessation of KI use prior to its ingestion by the individual. (See Emergency Telephone Directory for telephone number.)
°2) The Committed Dose Equivalent to the thyroid from radioiodine.

- b. control and track workers' dose, to limit their projected thyroid dose to 40 rem total organ dose. As warranted, ensure adjusted RWP controls and dose extensions are in place.
3.1.8 Should the projected dose to the thyroid not exceed 10 rem CDE (2)but the worker expresses the strong desire to use KI, the worker may do so at his/her own risk. In such case, the RPC or DASU as appropriate will inform the worker of the potential risks and benefits as described below and will recommend the person contact the CONSULTING RADIOLOGICAL PHYSICIAN for further guidance.
NOTE: Radiation exposure to the thyroid glands of adults does not appear to lead to cancer but has been shown to cause other deterministic effects (such as hypothyroidism resulting from thyroid ablation) from very high radiation doses to the thyroid.
For persons over 40 years of age, HHS/FDA recommends KI only for projected doses to the thyroid of above 500 rem, to prevent hypothyroidism.
The National Council on Radiation Protection and Measurement (NCRP Report No. 55) concludes that the risk of adverse effects from use of KI is on the order of 5 in 10 million.
In some cases, hyperthyroidism (excessive functional activity of the thyroid gland) is possible.
Those most at risk are patients with thyroid pathologies. This is most common in patients with goiter. This complication can be serious when the person also has heart disease. The risk of adverse effects is higher in adults of age 45 years and older, due to the frequency of diagnosed and sub-clinical thyroid disease and the use of certain prescription pharmaceuticals that would lead to a drug interaction.
(2) The Committed Dose Equivalent to the thyroid from radioiodine.
EP-AD-000-125, Revision 9, Page 5 of 13
Tab 5 EP-PS-247-5 PPL EMERGENCY PERSONNEL DOSE ASSESSMENT AND PROTECTIVE ACTION RECOMMENDATION (PAR) GUIDE CHECK 0 HHS/FDA observes that short-term administration of KI at thyroid blocking doses is safe. The risks of stable iodine administration include sialadenitis (an inflammation of the salivary gland), gastrointestinal disturbances, allergic reactions, and minor rashes.
Other risks may apply if repeated doses of KI are ingested.
3.1.9 If the individual states the intent to take KI absent a projected dose of 10 rem (CDE)(2) or more, the RPC or DASU will document in his/her logbook that individual's intent, that information on risks and benefits was described to the individual, and the statement that the individual was notified that ingestion was at the individual's own risk.
3.1.10 For an injured and/or contaminated worker sent to a hospital for treatment, the patient will be under the care of the attending physician. As such, plant procedures no longer apply and KI issuance will be at the discretion of the attending physician. The physician can rely on a senior Health Physics Technician Level II or Health Physics Management to provide the in-plant radiological data on which to base their decision.
Q 3.2 Protective measures should be implemented for EOF personnel at the direction of the DOSE ASSESSMENT SUPERVISOR, within the bounds of RWPs #8001 and #8002. Consultation with and approval by the RPC is needed for RWP revisions.
O 3.3 Exposures to members of local offsite support groups, (ambulance workers, fire fighters) shall not exceed 500 mrem (TEDE)(1) for the performance of support duties on the site of the Susquehanna SES.
°2) The Committed Dose Equivalent to the thyroid from radioiodine.
The sum of the Effective Dose Equivalent resulting from the exposure to external sources and the Committed Effective Dose Equivalent incurred from all significant inhalation pathways during the early phase.

Tab 7 EP-PS-247-7 CALCULATION AND TRACKING SHEET FOR ESTIMATED IODINE CDE AND TEDE DOSES USE THIS FORM:
(1,200 cpm frisker).
- 2. As directed by the TSC Dose Calculator or the DAST.
Methodology:
- 1. Initiate this form. Identify the affected team and the highest year-to-date (YTD) dose for any individual on the team.
- 2. Enter the time, current SRD dose and iodine to gamma ratio (Vy). (Note: Iodine to gamma ratio can be obtained from the RMS Emergency Field Monitoring Secondary Data ReporL)
The highest ratio obtained since tracking was Initiated shouldbe used (obtain from previously printed reports).
NOTE: If the SRD dose is less than 10 mrem enter "<10" in the SRD Dose Field, multiply the Vy times 10 and enter the CDE and TEDE doses as < dose value.
- 5. Notify the TSC Dose Calculator or DAST immediately and pull the team to a low background area if any member of a team reaches or exceeds the following:
TEDE = 3800 mrem CDE = 10,000 mrem TEAM: Year-to-Date (YTD) Dose:
Iodinelgamma Iodine CDE TEDE Date/Time SRD Dose(mrem) Ratio (VI) (mrem) (mrem)
