2. After the Media Center is operational and the media briefings have begun, the frequency of formal news statement development may be reduced at the discretion of the Emergency News Manager. The primary source of providing information is through news briefings.

Written outlines, summaries, status boards and graphics supplement information presented orally in the briefings.

3. The Emergency Operations Facility (EOF) and the plant organization serve as primary sources of plant-related information for the Media Center.

5.5 Briefings News briefings are the primary source for providing information to the news media and will be conducted on a regular basis, or as events dictate.

ER 3.5 Page 6 Rev. 24 News briefings will be conducted according to the following guidance:

1. News briefings at the Media Center will be managed by the Seabrook Station Emergency News Manager. Seabrook Station is responsible for information concerning onsite status and conditions. Seabrook Station news briefing presentations are based on plant status information confirmed by the Response Manager.

2. Public Information Officers from the states are responsible for releasing information relating to the impact of the emergency on the health and safety the public including off site radiological effects. As each agency prepares its information and statements, designated state spokespersons will participate in the news briefings.

3. At the discretion of the Emergency News Manager, the Technical Advisor may also participate in the news briefing. In a protracted emergency, assistance from subject matter experts and FPL Group executives may be obtained.

4. News briefing preparation is coordinated with representatives of the NRC, FEMA, and state agencies that are present at the Media Center.

5. Following a news conference, the key points presented to the media information used to respond to questions may be summarized and provided to the Media Center staff.

6. Briefing outlines are distributed to the Media Center staff for reference in carrying out their assigned function. The briefing outlines are not intended to be distributed to the news media.

5.6 Responses to Media Inquiries Responses to media inquiries regarding the plant status or Seabrook Station emergency response actions are confined to the information provided in approved news statements or briefing summaries; however, inquiries regarding general information about Seabrook Station (e.g.

building, component or system descriptions, capacity, etc.) can be responded to using supporting written public information material and graphic displays.

1. ERO personnel authorized to address media inquiries are as follows:

"* Emergency News Manager

"* Senior company official in accordance with the Seabrook Team Management Manual (STMM), Directive 4.0, Communications

"* Technical Advisor

"* Media Center Support Staff designated by the Emergency News Manager

"* Other Seabrook Station or FPL Group technical experts as designated by the Emergency News Manager

ER 3.5 Page 7 Rev. 24 5.7 Rumor Control Rumor control is accomplished as follows:

1. Monitoring news media coverage of the emergency and identifying any incorrect or misleading information so that Seabrook Station or the States may take appropriate action.

2. Coordinating emergency public information with the state and federal agency public information officers and obtaining feedback on rumor trends from the state agency rumor control telephone banks.

3. Expeditiously addressing incorrect or misleading information and rumor trends during news briefings or by direct contact with the source of the information (e.g., media outlet).

4. Maintaining a recorded information line with updated information on Seabrook Station emergency response and plant status. This line is accessible to the general public via a toll-free telephone number published in the annual public information material distributed to residents in the Emergency Planning Zone (EPZ), and provided during news briefings.

5. Monitoring Internet web sites for incorrect or misleading information.

5.8 Media Requests

1. Media tours of the EOF-portion of the building maybe conducted if they do not interfere with emergency and recovery activities. Such visits shall be approved by the Response Manager and arranged by the Media Center Support Staff.

2. Interviews with experts associated with Seabrook Station shall be arranged by the Media Center Support Staff under the direction of the Emergency News Manager.

3. Media tours of Seabrook Station are contingent upon plant conditions. Requests for tours of Seabrook Station shall be approved by the Response Manager and the Security Coordinator and may be conducted by Media Center Support Staff.

5.9 State/Federal Coordination in the Media Center

1. Initial focus of the ERO Media Center staff will be on identification of Seabrook Station key message points for public dissemination.

2. As state/federal public information officials arrive at the Media Center, until Seabrook Station key message points are identified, the Emergency News Manager will assign Media Center staff to orient them to the Media Center and to assist them with establishing their state/federal Media Center operations.

3. After Seabrook Station key message points have been identified, the Emergency News Manager will take the lead in coordinating Media Center activities with state/federal public information officials and exchange key message points with them.

ER 3.5 Page 8 Rev. 24

4. After the exchange of key message points between the utility and state/federal public information officials, the Emergency News Manager will determine the readiness of state/federal officials to participate in joint media briefings.

5. If state/federal public information officials are not yet present in the Media Center, or if they are not prepared to participate in joint media briefings, the Emergency News Manager will determine the official status of local, state and federal response (e.g., states have been notified, State Emergency Operations Centers are activated, public information officials are enroute) and brief the media accordingly.

NOTE The public needs to perceive clearly the cooperation and teamwork between the state and utility emergency response organizations. It is incumbent on the Emergency News Manager to work actively with representatives in the Media Center to establish this perception.

ER 3.5 Page 12 Rev. 24 Figure 4 Media Relations Telephone Guidelines Review the following information before answering phones.

(1) Sources of Official Information for Media Relations Staff: The Media Relations Staff shall use official Seabrook Station, State of New Hampshire, and Commonwealth of Massachusetts news statements or news releases, oral information as related by the Emergency News Manager or designee, and general, factual information as contained in written public information materials.

As general guidance, the staff should feel free to relate general, factual plan information such as how many people are involved in the Seabrook Station response organization, etc.

(2) Receipt of Phone Calls: Answer all calls according to your function. People are calling a specific number for a specific purpose; they should immediately know they got the right number.

"Hello, Seabrook Station Media Center. This is (First and Last Name). May I help you?"

Media Relations staff members shall give reporters their full name, since they are acting as spokespersons.

Reporters are required by their employers to identify themselves as reporters, and they should do so automatically. If they do not, ask for their name and affiliation. If they are unwilling to give that, they are probably not real reporters.

Explain to such callers that you are not authorized to talk to callers who refuse to identify themselves; refer them to appropriate rumor control numbers or taped message, if appropriate. You are there to help reporters only; refer members of the public seeking information to rumor control numbers or the Information Line.

(3) Interviews: Media Center staff shall conduct only telephone interviews. Special requests for additional interviews will be taken, but with no guarantees given to the press; efforts will be made to satisfy appropriate requests.

Radio: Media Center staff members are allowed to give taped interviews to radio stations for broadcast, with an understanding and agreement beforehand that information will be limited to the constraints outlined in the previous section. In addition, Media Center staff are allowed to go "live" on air to answer questions, subject to the constraints listed above.

Newspapers: Media Relations staff members are allowed to give newspaper interviews on the phone for attribution, subject to the above constraints.

Television: Media Relations staff members are allowed to talk to television reporters on the phone for attribution. Media Relations staff members do not give videotaped interviews to television reporters; encourage reporters to come to the Media Center where they can get taped interviews with appropriate spokespersons.

ER 3.5 Page 13 Rev. 24 Figure 4 Media Relations Telephone Guidelines (Continued)

Interviews shall be given only while filling an ERO role. You should inform the individual interviewing you that once the emergency has been terminated, all subsequent requests for information should be directed to Seabrook Station Communications. You will not be available for further interviews once the emergency has been terminated.

(4) Release of Phone Numbers: Under no circumstances should staff release EOF, EOC or other facility telephone numbers. Release only State or Seabrook Station approved emergency information numbers, as posted. As the emergency is terminated and the Media Center is deactivated, provide the telephone number for Seabrook Station Communications for follow-up after the emergency.

(5) Faxing of News Statements: The Media Center does not have resources to telefax news statements to news organizations. If a caller requests that you fax them a news release, politely inform them that they should consult the wire services for latest news release updates.

(6) Calls from Utilities: Callers from other utilities should be politely informed that 1) your purpose is to respond to media inquiries and 2) for information on the emergency, they may call the Institute for Nuclear Power Operations (INPO) or the American Nuclear Society (ANS), or review wire service reports.

(7) Calls Concerning Injuries/Deaths: For inquiries concerning injured or dead plant personnel, you may provide confirmation as to such an occurrence, if known and officially confirmed by the Response Manager. Do not release any individual's name or personal information unless specifically authorized to do so by the Response Manager. (After the Emergency News Manager has released this information at a news briefing, the Media Center Staff will have the flexibility to repeat this information to reporters who ask.)

ER 4.3 Page 5 Rev. 22 1.0 OBJECTIVES This procedure specifies the onsite radiation protection practices implemented following the activation of the Radiological Emergency Plan.

2.0 RESPONSIBILITIES 2.1 Radiological Controls Coordinator (RCC)

Directs Health Physics activities from the Operational Support Center (OSC) during an emergency. These practices will be implemented to maintain personnel exposure as low as reasonably achievable (ALARA). In an emergency situation some Health Physics practices may be different from the standard. The RCC will use his best judgment in an emergency situation to determine if such practices are included in standard procedures or not.

2.2 Health Physics Coordinator (HPC)

Coordinates Health Physics activities in the Technical Support Center (TSC), including job planning, monitoring TSC radiological conditions, communicating in-plant and near-plant radiological conditions to the Emergency Operations Facility (EOF) and advising the Site Emergency Director. The RCC will perform the functions designated in this procedure for the HPC until that position is filled.

2.3 Health Physics Technicians Carry out emergency actions as directed by the RCC aiid outlined in the emergency procedures.

2.4 Short Term Emergency Director/Site Emergency Director Authorizes emergency dose limits exceeding 4,500 mrem/current year.

3.0 PRECAUTIONS Onsite radiological conditions following an emergency event may be radically different from those associated with normal station operations and maintenance.

4.0 PREREQUISITES An Alert, Site Area Emergency, or a General Emergency has been declared in accordance with Procedure ER 1.1, Classification of Emergencies.

5.0 ACTIONS 5.1 Operational Support Center Control Activities 5.1.1 Access Control

1. The Health Physics control point remains the primary access point to radiologically controlled areas, including those resulting from the emergency event.

ER 4.3 Page 6 Rev. 22

2. The Radiological Controls Coordinator (RCC) directs the radiation protection activities at the Health Physics control point.

3. The RCC assists the Operational Support Center Coordinator in implementing emergency response and mitigating actions.

4. The RCC determines the need to alter the normal access controls provided by the radiation work permits and standing radiation work permits. The RCC initiates the use of Emergency Team Briefing/Debriefing Form, ER 3.2F, and the Emergency Exposure Tracking, Figure 5.

5. The RCC directs and assigns Health Physics personnel as appropriate in support of emergency actions.

6. Following an evacuation, the RCC designates a new Radiologically Controlled Area (RCA) access point with acceptable radiological conditions and assigns personnel as appropriate.

5.1.2 Radiation Exposure Control

1. Normal Process

a. The issuance and use of TLD dosimetry devices is documented on Figure 5, Emergency Exposure Tracking.

b. Dose rate indicating devices or alarming dosimeters shall be used for actions that require entry to unsurveyed areas, areas with dose rates that may rapidly or significantly change and areas where insufficient light prevents viewing pocket dosimeter readings.

c. Consult with the Radiological Controls Coordinator on dosimetry requirements for each team to be deployed into the plant.

d. If SRPDs are issued to OSC personnel or personnel deployed into the plant, the RCC will instruct personnel to read SRPDs at appropriate frequencies based on prevailing radiological conditions.

e. Initiate a Figure 5 form for each team member.

f. The requirements of 10 CFR 20.1201 are not applicable for the assignment of emergency exposure extensions.

g. The RCC may authorize administrative limits up to 4,500 mrern/current year without approval of the Short Term Emergency Director (STED) or Site Emergency Director (SED).

2. Emergency Doses Above 10 CFR 20.1201 Limits

a. Approval for exceeding 4,500 mrem/current year shall be obtained from the STED or SED prior to initiating any action that has the potential to result in such exposure.

ER 4.3 Page 7 Rev. 22

b. The emergency dose limits and the criteria for authorizing their use are contained in Figure 2, Emergency Dose Limits.

c. Guidance on emergency occupational dose is listed in Figure 3, Dose Guidance.

d. The RCC or HPC initiates Figure 4, Emergency Dose Limit Extension, and confers with the STED or SED to determine appropriate action.

e. The STED or SED may issue a blanket emergency dose limit authorization if radiation levels at the Station will cause emergency center personnel to exceed normal limits before protective action is taken in accordance with Figure 1, Emergency Center Protective Action Criteria.

f. Radiation exposure incurred from obtaining and analyzing pass samples should not exceed the limits of 10 CFR 20.1201. Refer to Figure 8 for guidance on allowing sampling from the normal sample sink versus using PASS survey team.

3. Emergency Plan Radiation Work Permit (Eplan RWP)

a. The Eplan RWP is maintained in standby for emergency use.

b. The purpose of the EPlan RWP is to track dose and control radiation exposure during declared radiological emergencies.

c. The EPlan RWP has multiple tasks for various electronic alarm setpoints.

d. The EPlan RWP is issued and on HOLD.

e. The RCC will determine when to use the EPlan RWP and to take if off HOLD.

f. Use of the EPlan RWP may require modification of MGAC dose limits based on which task is selected by the RCC and the assigned individuals' current accumulated dose.

g. Dose alarms for some tasks may require emergency dose limit extensions per ER 4.3, Section 5.1.2, sub-section 2.

5.1.3 Egress Control

1. If radiological conditions permit, the Health Physics control point remains the primary RCA egress location.

2. Unless directed by the RCC, the following RCA egress controls are used during emergency conditions:

a. Whole body frisking,

b. Portal monitor checks,

ER 4.3 Page 8 Rev. 22

c. Applicable debriefings, and

d. Special dosimetry/equipment return.

3. Based on RCC direction, Health Physics will establish alternate egress control location(s) including contamination monitoring and dose information retrieval.

4. Contamination monitoring may be hindered by background radiation levels.

5.1.4 Radioactive Material/Contamination Control

1. Under emergency conditions, radioactive material and contamination controls are established at a level commensurate with the urgency and complexity of required actions.

2. The RCC and assigned Health Physics personnel determine controls either at the emergency team briefing or at the worksite.

3. Intentional movement of radioactive material outside the RCA requires approval and/or escort by Health Physics personnel.

5.1.5 Respiratory Protection

1. When selecting appropriate respiratory protection equipment, the RCC evaluates the benefit of respiratory protection versus the radiological hazard and interference with performing the required action.

2. The RCC will consider the criteria in Figure 1 to determine when emergency response personnel should wear a respirator. Respirators and filter canisters for emergency use are located in the OSC. A supply of this equipment is also available in the Security Building should the RCC determine that use of respiratory protection equipment is appropriate for Security personnel stationed or deployed from there.

3. For certain critical missions (e.g., life saving), the RCC may authorize use of a respirator by emergency response personnel who have not qualified for respirator use under the station respiratory protection program. In each case, the RCC will screen the emergency worker using the screening questions in Figure 7. Any "YES" answer to a screening question will preclude use of respirator by the individual emergency worker.

ER 4.3 Page 9 Rev. 22

4. The RCC determines the need to dispense potassium iodide (KI) tablets to emergency response personnel based upon a projected or actual thyroid committed dose equivalent (CDE) >5 rem. The thyroid CDE >5 rem threshold is based on the FDA recommended threshold for ingestion of KI by pregnant and lactating women (Ref. 6.17). Consider removing emergency response personnel who meet this description from the ERO.

A quick method to calculate the thyroid CDE using an RM-14 or equivalent count rate meter is as follows:

Place a frisker probe on the collection face of the cartridge and determine corrected counts per minute (ccpm).

3 Thyroid = (net cpm) x (stay time in hrs) x 5.2E-3 rem-ft CDE (rem) (vol ft3) cpm-hrs

5. When KI tablets are issued, thyroid intakes will be estimated by whole body counting.

6. Administering KI after an uptake may limit thyroid CDE depending on time after exposure.

7. Caution emergency response personnel of potential KI side effects if they are allergic to shellfish or iodide. Emergency response personnel who know they have such allergies should be replaced in lieu of directing them to ingest KI.

8. Log any issuance of KI tablets on KI Issue Log, Figure 6.

5.1.6 Use of the Radiation Data Management System

1. The RCC monitors the Radiation Data Management System at the OSC.

NOTE RDMS users should be aware that during elevated radiation conditions, the automatic performance of routine check source tests by the system could be inhibited per Reference 16.

2. As radiation levels change due to emergency conditions, the RCC may authorize new alarm setpoints, inputs required commands and notifies the Control Room of changes.

3. Not all monitor alarm setpoints can be changed at the RDMS console; these monitors will be set by the Control Room.

ER 4.3 Page 10 Rev. 22 5.2 Protected Area Radiological Surveillance and Control 5.2.1 Security Gatehouse Functions

1. All personnel exiting the protected area through the Security Gatehouse shall use the portal monitors to check for contamination if background radiation levels permit.

2. If an individual alarms a portal monitor twice, indicating the presence of contamination, Security shall notify the RCC and shall request the individual to remain on the protected-area side of the portal monitor until Health Physics personnel arrive.

3. If site evacuation has been ordered, contaminated individuals may be directed to the Remote Monitoring Area.

4. Security notifies the RCC if the background at the Security Gatehouse is causing spurious portal monitor alarms or if an alarm has occurred on local area monitors.

5. The RCC directs Health Physics personnel to respond to the Gatehouse or forward security command post as necessary.

6. Security notifies the RCC of alternate protected area access and egress points established due to site evacuation.

7. The RCC ensures that appropriate contamination monitoring equipment is assigned to the security location.

5.2.2 Assembly Area Monitoring

1. The RCC assesses the need to monitor personnel at assembly areas and onsite emergency facilities.

2. The RCC assigns Health Physics personnel to monitor the assembly areas for airborne radioactivity and background radiation.

3. Assembled personnel perform self-monitoring for contamination as directed by the RCC.

4. The Health Physics Coordinator advises the Technical Services Coordinator and/or Site Emergency Director of appropriate protective actions for the assembly areas.

5. The Health Physics Coordinator specifies the primary and alternate evacuation routes if such site evacuation is necessary based on actual or potential radiological conditions.

6. The RCC assigns Health Physics personnel to supervise monitoring of station evacuees at the Remote Monitoring Area.

ER 4.3 Page 11 Rev. 22 5.2.3 General Radiation/Contamination Surveillance

1. The RCC directs Health Physics personnel to monitor general station areas based on actual and potential radiological releases.

2. The RCC implements increased controls and monitoring as necessary, including placement of area TLDs, frisking stations and step-off pads.

5.3 In-Plant Surveillance and Control 5.3.1 Radiation/Contamination Surveys and Posting

1. The routine surveillance requirements of Procedure HD0958.17, Performance of Routine Radiological Surveys, are suspended until the RCC determines Station conditions are stable and general area surveillance is feasible.

2. The RCC establishes the emergency survey requirements based on actual or potential radiological conditions (i.e., refer to Post-Accident Engineering Manual for projected dose rates and guidance).

3. The RCC notifies the Operational Support Center Coordinator and Health Physics Coordinator of abnormal radiation survey results and advises on precautionary measures to control exposure during required entry to affected areas.

4. To the extent feasible, the RCC directs the posting of contamination areas, high radiation areas and isolation of extremely high radiation areas.

5.3.2 Airborne Radioactivity Monitoring, Sampling and Posting

1. Due to the potential for very high airborne activity along with possible high radiation levels, the normal sampling volume used may be reduced.

2. The RCC will develop a program for placement and changeout of low volume air samplers to monitor the possible migration of airborne radioactivity.

3. Battery-powered air samplers are used for grab samples when electrical power is not available.

4. Consider the use of silver zeolite for radioiodine sampling for speed of analysis when noble gas interference is suspected or when the gamma spectroscopy system is unavailable (Protected: Ref. 6.10).

CAUTION Do not use silver zeolite cartridges in explosive environments.

ER 4.3 Page 12 Rev. 22 5.4 DAC-Hour Accountability

1. The RCC directs the tracking of Derived Air Concentration-hours (DAC-hours) based on the authorized RCA access mode.

2. If necessary, whole body counting will be used to assess accumulated DAC-hours.

5.5 Dose Assessments 5.5.1 External Dosimetry Evaluations

1. The RCC will direct the special processing of an individual's TLD.

2. An EOF Dosimetry Return Card (ER 3.3, Figure 14) shall be completed for dosimetry returned to the EOF. Special requirements for readout or dose notification shall be indicated under the "Comments" section.

3. The dosimetry lab will forward a copy of or transmit all special processed TLD results to the RCC.

4. Emergency doses for individuals in excess of the annual limits of 10 CFR 20.1201(a) are to be subtracted from the current year planned special exposure limits for the individual.

5.5.2 Exposure Tracking I. Determine initial dose information from the most recent Exposure Status Report, FINIS-RPMS or from YTD Transit Card (ER 3.3, Figure 13), for previous unmonitored workers.

Using FINIS-RPMS to determine the current year to date (WBYTD) exposure for an individual:

RPEWBSUM[SS#, Security Badge (4 digit) or Name]

2. If the use of RWP/SRWP sign-in sheets is not practicable, personnel dose will be tracked using the Emergency Exposure Tracking, Figure 5.

3. The RCC will send the dosimetry of personnel accumulating emergency exposures of 4,500 mrem or greater to the EOF with a completed EOF Dosimetry Return Card (ER 3.3, Figure 14) for TLD processing.

5.5.3 Extremity Monitoring

1. The possibility of high localized areas of radiation in equipment and the reactor coolant increases significantly during many accidents. Extremity monitoring should be strongly considered for any maintenance/sampling evolutions.

ER 4.3 Page 13 Rev. 22

2. Used extremity dosimeters along with a zeroed low- and high-range SRPD shall be returned to the Dosimetry Records personnel in the EOF for TLD readout. The location of the extremity dosimeter (e.g., left hand, right hand) shall be identified in the "Comments" section of the EOF Dosimetry Return Card (ER 3.3, Figure 14). (Protected: Ref. 6.11) 5.5.4 Bioassavs The RCC will establish the frequency and type of bioassay monitoring program implemented based on available air sample data, number of personnel exposed/contaminated, and the extent of their exposure/contamination.

5.5.5 Abnormality Evaluations When relatively large doses are involved, any discrepancy between dosimeter or expected dose and the TLD dose should be investigated immediately and referred to the RCC for final disposition.

5.6 Decontamination 5.6.1 Offsite Use procedure ER 4.6, Offsite Monitoring and Decontamination, for monitoring and decontamination of evacuated onsite personnel and emergency responders assigned to offsite facilities.

5.6.2 Personnel

1. During normal operations the goal of personnel decontamination, is the complete removal of the contamination. In an emergency situation this goal may change to reducing contamination levels as quickly as possible to an acceptable level.

2. The RCC will establish the acceptable level for personnel decontamination.

5.6.3 Area and Equipment The RCC will determine the need and direct the methods to be used for major equipment or area decontamination.

5.7 Medical Emergency

1. The time needed for proper radiological precautions (i.e., clothing, respiratory, etc.) may not be available in a medical emergency. The Health Physics Technician assigned to the medical emergency will monitor personnel doses as needed.

2. The RCC will supply Health Physics personnel as necessary to assist in maintaining radiological conditions as stable as possible without delaying the treatment/transport of the victim.

3. Health Physics personnel will respond in accordance with Health Physics Department procedures.

ER 4.3 Page 14 Rev. 22 5.8 RCA Fire

1. The RCC will direct the radiological actions to be performed for a fire in the RCA.

2. Self-contained breathing apparatus is the only acceptable respiratory protection to be used in the vicinity of a fire.

5.9 Post-Accident Sampling Radiological considerations for post-accident sampling are taken into account by the following:

1. Design of the PASS panel intended to limit exposure to personnel operating the panel.

2. Sampling techniques prescribed by post-accident sampling and analysis procedures designed to limit personnel exposure and spread of contamination.

3. Pre-deployment briefings by the Chemistry Coordinator and Radiological Controls Coordinator of PASS team personnel per form ER 3.2F, Emergency Team Briefing/Debriefing Form.

ER 4.3 Page 24 Rev. 22 Figure 8 Decision Guidance For Use of RCS Normal Sample Path Versus PASS The following guidance for using the normal sample path with elevated RCS activity is derived from HPSTID 00-013:

Letdown Monitor PASS Survey Port Recommendation Reading (mR/hr) Reading (R/hr)

Notes: 1) Normal letdown or RH letdown in service (not RH slipstream, RM-6520 is bypassed during slipstream operation).

2) Determined using RO-7 mid range probe with beta shield installed.

This guidance is based on the calculated dose to obtain and analyze a 60 ml RCS liquid and strip gas sample.

3. Estimating Team Dose to Obtain a PASS Survey Port Reading When evaluating the dispatch of a PASS survey team, the team dose (50% WB to HP Technician, 50% WB to Chemistry Technician, and 100% Extremity to HP Technician obtaining the dose rate) may be estimated using the sample room radiation monitor.

"* The estimated team extremity dose (mrem) equals 20 times the sample room monitor reading (mR/hr).

"* The dose rate in front of the open PASS Survey Port may be estimated by using the sample room radiation monitor reading and applying a multiplier of 115 to obtain the estimated extremity dose rate in front of the survey port with the shield plug

ER 4.3 Page 28 Rev. 22 Figure 11 Evaluating Gamma Dose Rate Decay of RCS Samples in Archive or RCS Activity for Future Sampling and Handling Decayed dose rates on RCS samples obtained and held for future analysis or to be obtained following some decay period post reactor (Rx) shutdown may be determined using the plotted data in Chart 3. T=0 is specific to Rx shutdown (SD); therefore, comparisons must be made between the time obtained and the time desired (e.g., the delta between a sample archived at 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> post Rx SD and 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> post Rx SD is 0.4/0.08 = a factor of 5 lower dose rate). This may also be used to decay a previously obtained Letdown Monitor or PASS Survey Port value or normal sample panel dose estimate when evaluating future RCS sample team activities.

ER 5.3 Page 3 Rev. 19 1.0 OBJECTIVES This procedure provides instructions for the operation of METPAC, a software package developed to produce dispersion and offsite dose estimates during an accidental release of radioactive material.

2.0 RESPONSIBILITIES 2.1 METPAC Operator Operates the METPAC system.

3.0 PRECAUTIONS

1. Periodically check on the quarter-hour for significant changes in meteorological conditions.

2. Do not terminate the program in the middle of a run; this may crash the program. Return to Screen One and select Q to terminate.

3. The dose rate projections produced by this procedure represent a best estimate. If projections from in-plant parameters are significantly different from those measured in the environment, it may be due to inaccuracies in meteorological modeling and/or release rate estimates. The results obtained from this procedure should be carefully analyzed since they may form the basis for protective action recommendations to the public.

4. The existence of a seabreeze can significantly affect plume transport and diffusion as predicted by METPAC. Seabreeze effects occur primarily from April through September during the daylight hours. Necessary conditions include sunny days when the sun warms the ground and the ground surface air temperatures rise significantly above the ocean and bay water temperatures.

A shift of onsite wind direction from offshore to onshore (onshore being defined as winds from 22E clockwise to 173E) occurring sometime during daylight hours can be indicative of a seabreeze front passing the site. Existence of a seabreeze front inland from the site can be confirmed by comparing onsite wind data with wind data from inland stations (e.g., Concord NWS).

If an inland seabreeze front exists, the plume will rise several hundred feet above ground upon reaching the front and be directed back towards the shoreline. As a result, there will be (i) little dose inland from the seabreeze front, and (ii) a low dose elsewhere between the seabreeze front and the shoreline where the plume passes several hundred feet overhead in the return flow.

5. When the containment failure model is executed in "batch execution" mode and produces a release duration of less than one hour, a thyroid shelter protection factor of 0.5 should be manually applied to the total thyroid dose. (Protected: Ref, 6.3)

ER 5.3 Page 4 Rev. 19

6. If steam line pressure is indicated as less than 50 psig, enter 50 psig as the steam line pressure.

7. All times must be entered in 24-hour-clock notation.

8. All items must have proper values. No error checking is done until after the user has completed the input screen. If there are errors with the input, the terminal will beep, a message will appear above the input screen and the cursor will automatically move to the input location that is in error. The correction values must be inputted followed by a (CR).

Once the value has been corrected, the program will continue error processing.

9. In the event that the Wide Range Gas Monitor (WRGM) is inoperable and the WRGM Backup Monitor has been activated, initiate Figure 4, WRGM Backup Monitor Data Calculation Sheet, and input the Effective WRGM Stack Concentration and Release Rate from this form as the STACK CONCENTRATION and STACK RELEASE RATE on the Radiological Data Screen.

10. Data entry limitations can be recognized by use of the "Prompt" selection.

11. Refer to the Technical Description of the SB METPAC System for isotopic breakdown of LOCA types.

12. The two-phase flow release pathway from a Main Steam Line (MSL) incorporates correction factors for the calculation of TEDE and thyroid CDE. (Protected: Ref. 6.12)

13. Monitor response entries will calculate offsite dose rate conditions based on an assumed mixture of noble gas and iodine concentrations. (Protected: Ref. 6.9)

14. METPAC assumes a default release duration of 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

4.0 PREREQUISITES For purposes of requiring offsite dose assessment (i.e., a METPAC run), a release is defined as follows:

1. Wide Range Gas Monitor (WRGM) High Alarm (RM-6528-4),

2. Main Steam Line Monitor High Alarm with an OPEN ASDV or SRV on the affected main steam line,

3. The results of effluent analysis or site boundary monitoring indicate a dose rate greater than or equal to 0.06 mrem/hr.

ER 5.3 Page 5 Rev. 19 5.0 ACTIONS 5.1 METPAC Operator

1. Turn on the METPAC Operator's computer and printer. Each piece of hardware can be turned on manually or all units can be powered through a master switch on the multiple outlet strip in which the units are plugged. The system should display a menu screen with 3 alternative programs:

- METPAC

- INGEST - (The METPAC Operator's computer will operate INGEST)

- ODPS

2. Turn on the Dose Assessment Specialist's computer and printer. The Dose Assessment Specialist's METPAC system may be used either to review postulated worst case release scenarios or to provide a backup to the METPAC Operator's system.

3. At the prompts, type in METPAC on either system followed by a carriage return (CR).

The system should begin executing the METPAC program and current analysis conditions will be outputted on the screen at this time. Refer to Figure 2 for information on special keys used by METPAC.

4. If the METPAC system does not execute, the user may reload the system with the backup diskettes which are available in the Dose Assessment Area, as follows:

a. Turn on the system.

b. After entry of date and time, load the METPAC reload disk 1 into drive A.

c. Type: A:Reload (CR).

d. Follow any further instructions as specified on the screen (usually for loading other disks).

This procedure should return METPAC to its original state. Any analysis previously performed will be lost.

5. Obtain a logger trend printout with data needed to run METPAC from the Technical Assistant. In the event that a logger trend printout is not available, obtain this information from the Technical Assistant or Health Physics Coordinator (in the TSC) as necessary, and record the data on the METPAC Input Data Log, Figure 7.

6. If the system is functioning properly, the Main Menu screen should appear. Select one of the following six options by moving the cursor key up or down to the option to be selected. For more information on METPAC Options refer to Figure 1, Options.

1 - START NEW ACCIDENT

ER 5.3 Page 6 Rev. 19 2 - CONTINUE ACCIDENT 3 - ELIMINATE LAST 1/4 HOUR ANALYSIS 4 - OBTAIN OUTPUT 5 - BATCH EXECUTION Q- QUIT

7. Upon selecting option I (START NEW ACCIDENT), the user will be prompted to keep previous data. The user should enter Y to initiate a new accident analysis. Entering N will return the user to the Main Menu screen to select another option.

8. Refer to specific screen entry instructions in Figure 8, METPAC Data Entry Screen Guidance. Enter the appropriate parameters for the various screens by using the information on the logger trend or Figure 7, METPAC Input Data Log. A listing of all METPAC function keys is presented in Figure 9, METPAC Function Key Listing.

9. Depress the EXIT function key (F10) to start the next quarter-hour analysis. This will clear the screen and display the first input screen.

10. After completing each dose projection run, obtain the "Tracking Report" printout. Verify the METEOROLOGY data on the Tracking Report against the Logger Trend or Figure 7 input data. Ensure that LOWER Wind Speed, Wind Direction and Delta Temperature values were used, except in the case of a Stack Release when UPPER Wind Speed, Wind Direction and Delta Temperature values must be used. Turn over results to the Dose Assessment Specialist (DAS) for review and validation. If the DAS is not available, report information to the EOF Coordinator. (Protected: Ref. 6.13)

11. If time permits, the METPAC Operator should try to generate a hardcopy of one projected map per fifteen-minute period and should not go beyond 30 minutes without a graphic printout. The map hardcopy is generated by depressing function key F9.

12. The Status Board Report should be used for status board updates. The Status Board Report is generated by depressing function key Fl, followed by function key F4. If the system cannot access the Status Board Report (function keys Fl, F4), fill out a Radiological Status Board Update Form, available in Procedure ER 3.3, Emergency Operations Facility Operations. Make necessary changes and direct the information to be posted on the status board by the Dose Assessment Personnel.

13. Ensure copies of the latest printouts are made and delivered, or are placed appropriately for pickup.

14. Maintain a file of printouts and logger trends. Maintain completed METPAC Input Data Logs (Figure 7) if used in place of logger trends.

ER 5.3 Page 7 Rev. 19

15. Continue to obtain updates on plant radiological release and meteorological information using the logger trend printout, or Figure 7 if necessary. When possible, make time advance projection(s) by advancing through the input screens. This assumes the meteorological and radiological data have not changed. Use Option 3 (eliminate last 1/4 hour of accident) when more than one projection has been made and current data becomes available. Option 2 (CONTINUE ACCIDENT) and the edit mode should be used to change the first projection time of analysis to that of the latest data. This procedure minimizes the amount of new data that must be input.

16. When appropriate, return to the main menu and select "QUIT" to exit METPAC program.

17. Turn in all data sheets and printouts from METPAC to the Dose Assessment Specialist.

ER 5.3 Page 12 Rev. 19 Figure 4 WRGM Backup Monitor Data Calculation Sheet This figure is to be used to calculate the "Effective" WRGM Stack Concentration and "Effective" WRGM Stack Release Rate from the output of the WRGM Backup Monitor (WBM).

1. Obtain the WBM reading from the Technical Support Center:

A = WBM reading = mR/hr

2. Determine the Time After Shutdown (TAS) and obtain the WBM Correction Factor (WBMCF) from the table below:

TAS in hours WBMCF

=1 0.175 If TAS does not match listed TAS hours, round down 2 0.183 (e.g., if TAS = 8, use TAS 7 WBMCF 0.252) 5 0.223 7 0.252 10 0.294 20 0.437 50 1.10 70 1.71 100 2.13 200 2.26 500 2.27 700 2.25 1000 2.18 B = WBM Correction Factor (WBMCF) = igCi/cc mR/hr

3. Obtain the Stack Flow Rate from Logger Trend, Main Plant Computer Data Point RM-6528-4 "PF PLANT VENT DISCH FLOW" or Figure 5, Plant Vent Stack Flow Summarization, and convert to cc/sec as necessary*

C = Stack Flow Rate = CFM x 472 cc/Sec = cc/sec CFM

4. Calculate the Effective WRGM Stack Concentration and Release Rate:

D = Effective WRGM Stack Concentration = A x B = ACi/cc E = Effective WRGM Stack Release Rate = C x D = "_Ci/sec

ER 5.3 Page 13 Rev. 19 Figure 5 Plant Vent Stack Flow Summarization The following list represents the operating fans and respective flow rates for the various modes of plant operation. All flows are in CFM.

If a fan is shut down, assume a total stack flow reduction of 50% of the shutdown fan flow value. For example, if WAH-FN-13A is shut down, normal conditions stack flow would be 276,160-(151,620/2)(.5)=238,255 CFM. Only the fans listed below should be considered when calculating flow reductions.

ER 5.7 Page 3 Rev. 23 1.0 OBJECTIVES This procedure provides instruction for operation of the Offsite Dose Projection System (ODPS).

This software program projects the Total Effective Dose Equivalent (TEDE) and adult thyroid Committed Dose Equivalent (CDE) dose rates and doses at the site boundary, and 2, 5 and 10 miles. It also assists in the determination of the emergency classification level and protective action recommendations.

2.0 RESPONSIBILITIES 2.1 Shift Manager/Short Term Emergency Director Performs or directs operation of the ODPS in the Control Room.

2.2 Work Control Supervisor Operates ODPS at the direction of the Shift Manager/Short Term Emergency Director.

2.3 Health Physics Coordinator Operates ODPS in the Technical Support Center (TSC).

3.0 PRECAUTIONS

1. The program can be exited at only two locations. The first appears at the end of input data entry-, the second appears at the end of an ODPS execution. To exit, type -1 followed by the enter key.

2. Operation of this program requires meteorological data from the onsite meteorological monitoring system.

3. Monitor response entries will calculate offsite dose rate conditions based on an assumed mixture of noble gas and iodine concentrations. (Protected: Ref. 6.9)

4. ODPS maybe run from the following Main Plant Computer System (MPCS) terminals in either the Control Room or TSC.

a. Shift Technical Advisor (STA) work station

b. Shift Manager work station

c. The TSC terminal at the Health Physics Coordinator's work station.

5. In the event that the MPCS terminals become inoperable, backup laptop computers with ODPS are maintained in the Control Room and in the TSC.

6. When available, the meteorological data used for ODPS run should be the 15 minute average values.

ER 5.7 Page 4 Rev. 23

7. The step-by-step program operating instructions contained in this procedure are for reference purposes as needed by the ODPS Operator.

8. All items must have proper values within a defined range. Error checking is done as each value is entered. Entry of an invalid value causes a message to appear at the bottom of the screen. The program will continue when an acceptable input value is entered.

9. In order to obtain data from the MPCS, a file containing the data must be available. The data in this file will be read and used for displaying input values which the operator will have the option of changing. Any changed values will be displayed in bold type.

4.0 PREREQUISITES A release of radioactive material has occurred as indicated by one of the following:

1. Wide Range Gas Monitor (WRGM) high alarm (RM-6528-4),

2. Main Steam Line Monitor high alarm with an OPEN Atmospheric Steam Dump Valve (ASDV) or safety relief valve (SRV) on the affected line,

3. The results of effluent analysis or site boundary monitoring indicate a dose rate greater than or equal to 0.06 mrem/hr.

5.0 ACTIONS 5.1 ODPS Operator

4. The computer will display the date check prompt:

Current date is DAY MM-DD-YYYY Enter new date (mm-dd-yy):

a. If date is correct, press the enter key and the program moves to time check prompt. If date is incorrect, input current date using mm-dd-yy format then press the enter key. The program responds with the time check prompt:

Current time is HH:MM:SS Enter new time:

b. If time is correct, press the enter key. If time is incorrect, input current time using 24-hour clock format, hhbmm:ss, then press the enter key.

NOTE If running on a non-STA work station and depending upon the computer Disk Operating System, the date and time checks performed in steps a and b, above, may be repeated. If so, perform steps a and b again, and then proceed to step 5.

5. Obtain data needed to run ODPS from logger trend printouts, the main plant computer system, or other plant indicators.

NOTE RDMS group trend 14, EPLAN MONITORS, maybe used as a ready source of ODPS input data.

a. If a downloaded MPCS data file is available or logger trend printouts are used, it is not necessary to enter run input data on form ER 5.7B, ODPS Worksheet. (If needed, refer to Logger Trend Instructions, which are listed in Figure 4.)

b. If both downloaded MPCS data files and logger trend printouts are unavailable, enter run input data on form ER 5.7B. (If needed, refer to Dose Assessment Data Points, which are listed in Figure 1.)

ER 5.7 Page 6 Rev. 23

6. Enter input data at the various prompts listed below and follow each entry with the enter key.

7. IS THE PLANT ALREADY IN A G.E.? (Y/N) Enter based on the emergency classification in effect at the time of the ODPS run.

8. TIME AFTER SHUTDOWN (HRS) Input the time duration between the reactor shutdown or trip to the time of analysis. Use hours and decimal fractions of hours (0-1000 hours).

CAUTION If a release is indicated through more than one of the following pathways, run the program once for each pathway and use the most conservative PAR result (e.g., if PAR Group A is indicated for one run and PAR Group B is indicated by another run, use PAR Group B).

9. RELEASE PATH (STACK=l, STEAM=2, CONT=3, UNMON=4) Depending on the release path, input the number that corresponds to a stack release (1), main steam line release (2), containment release (3), or unmonitored release (4).

ER 5.7 Page 13 Rev. 23 Figure 3 Plant Vent Stack Flow Summarization The following list represents the operating fans and respective flow rates for the various modes of plant operation. All flows are in CFM.

If a fan is shut down, assume a total stack flow reduction of 50% of the shutdown fan flow value. For example, if WAH-FN-13A is shut down, normal conditions stack flow would be 276,160 (151,620/2)(.5)=238,255 CFM. Only the fans listed below should be considered when calculating flow reductions. Smaller support fans not listed below (e.g., WAH-FN-125) should not be considered in a flow reduction calculation.

ER 5.7 Page 14 Rev. 23 Figure 4 Logger Trend Instructions The main plant computer logger trend is a printed report of selected plant parameters to support accident assessment, including offsite dose projections. Once enabled, the logger trend report will print out every quarter hour until the report is disabled. The logger trend may run in the background, that is, continue printing while using the main plant computer terminal to look at other parameters.

Using a main plant computer keyboard, initiate the logger trend as follows:

1. From the main menu screen, select "LOGS."

2. From the LOGS menu screen, select "FREE FORMAT."

3. Push F1 function key (ACTIVATE).

4. Enter number corresponding to TSC LOG or EOF LOG.

Using a main plant computer keyboard, disable the logger trend as follows:

WRGM Backup Monitor Data Calculation Sheet This form is to be used to calculate the "Effective" WRGM Stack Concentration and "Effective" WRGM Stack Release Rate from the output of the WRGM Backup Monitor (WBM).

1. Obtain the WBM reading from the Technical Support Center:

A = WBM reading = mrem/hr

2. Determine the Time After Shutdown (TAS) and obtain the WBM Correction Factor (WBMCF) from the table below:

TAS in hours WBMCF

<1 0.175 If TAS does not match listed TAS hours, round 0.183 down (e.g., if TAS = 8, use TAS 7 WBMCF 2

0.252).

3. Obtain the Stack Flow Rate from Logger Trend, Main Plant Computer Data Point "PF PLANT VENT DISCH FLOW" or Figure 3, Plant Vent Stack Flow Summarization, and convert to cc/sec as necessary:

C = Stack Flow Rate = CFM x 472 cc/Se.. cc/sec CFM

4. Calculate the Effective WRGM Stack Concentration and Release Rate:

D = Effective WRGM Stack Concentration = A x B = tCi/cc E = Effective WRGM Stack Release Rate = C x D = 4Ci/sec ER 5.7A Rev. 21 Page 1 of I
