DBNPS. Non-terrorism-based EALs should be used to address such activities (i.e., this may include violent acts between individuals in the OWNER CONTROLLED AREA.

Kl FOR THE GENERAL'PUBLIC - Recommending potassium iodide (Kl) for the general public is the responsibility of the State of Ohio Department of Health. The station will recommend to the State administrating Kl in accordance with· State procedures upon declaration of a General Emergency.

KNOWN IMPEDIMENTS TO EVACUATION - Those conditions that may affect the ability to evacuate a large portion of the population within the 'Emergency Planning Zone (such as inclement weather, roadway/bridge damage following a natural event). State or

' counties must have provided prior knowledge of these impediments to the utility prior to the Protective Action decision-making.

LAKE BREEZE - A meteorological condition that may occur on clear, sunny days. During a lake breeze, a radioactive release can travel inland, rise, reverse course in,an overhead return flow, and then return to land in a convoluted path.

MINIMUM RADIOACTIVE RELEASE PROTECTIVE ACTION ' .

RECOMMEND A TIO NS (PAR) - At a minimum a PAR will be issued for Subarea 1, Subarea 12, and affected downwind subareas within five miles.AND advise the general public to take Kl iri accordance with the Ohio Plan for Respbnse to Radiation 'Emergencies

, at Licensed Nuclear Facilit1es. . . .. ; . . .

3.13 MONITOR AND PREP ARE - Guidance provided to the population within the Emergency Planning Zone, typically for those Sheltering in Place. This advices the public to maintain ah awareness of the event through media broadcasts and subsequent Emergency Alert System messages. The public ~hould make preparations for evacuation ( or other protective

3.14

actions) as directed. . .

OFFSITE - Any area outside the Owner Controlled Area surrounding Davis-Besse Nuclear Power Station. · ·

RAPIDLY ESCALATING SEVERE ACCIDENT - This describes an accident in which there has been significant degradation of the.reactor core, 'and because of the accident, the integrity of Containment is challenged. It is postulated that this accident will result in a significant release of.radioactive 111a(erial and sub~equent dose to the public.

3.21

SHORT-TERM (PUFF) RELEASE-A contn;>lled venting ofradioactive gases (usually from Containment), sometimes referred to as a "puff' release. To be considered a shortterm release,jt must meet a_ll o.fthe following criteria: • Initiated by the operator, not the accident. • Performed in a controlled manner and able to be secured, if necessary • · Monitored by effluent radiation monitors ( e.g:, Station Vent radiation monitors) • Short-term (:S 1 hour) • Doses are less than EPA guidance

: \

TOTAL EFFECTNE DOSE EQUN ALENT (TEDE) - The sum of the deep-dose equivalent (for external exposure) and the Collllllitted Effective Dose Equivalent (for internal exposure).

4.0 RESPONSIBILITIES

5.0

4.1 The Emergency Director is responsible for directing protective actions for Station personnel and recollllllending protective actions to offsite officials for the Plume Exposure Pathway (IO-mile EPZ). · ·

4.2 The Dose Assessment Coordinator is responsible for collecting and analyzing offsite dose assessment data used to provide the basis for protective action recollllllendations.

ANY CONDITION THAT JUSTIFIES ISSU1NG AN OFFSITE PROTECTIVE ACTION REQUIRES~- GENERAL EMERGENCY DECLARATION. ·

O:ffsite Pr~tection Action Recommendations shall be made with · initial notification of a General Emergency.

• · Davis-Besse will always recommend EVACUATiON.of Subarea ·12 (Lake Erie) and when appropriate·subarea 10 (Wildlife area) due to lack of shelters in these areas.

• A SHELTERING PAR will NOT be issued for any subarea in which an EVACUATION PAR has already been recommended .

. : ~' .

6.2 Offsite Protective Actions

6.2.1 Refer to Attachment 1 to determine recommended Protective Action Recommendation.

.. CAUTION 6.2.2. · Protective Action Recommendations once issued start in motion a sequence of events in the 10-mile emergency planning zone that, if modified, have the potential to cause confusion that may hamper the orderly implementation of protective actions for the general public.

6.2.2 Notify offsite agencies and the NRC of the PARs and the affected subareas using RAEP-02110, Emergency Notification, and Initial Notification Form, DBEP-010.

a. IF these are revised P ARs THEN DO NOT downgrade a previously issued PAR for a specific subarea until the conditions that caused the PAR to be issued are fully under control. The new PAR should include those subareas that were previously evacuated or sheltered and any new subareas.

b. IF a lake breeze is occurring, the wind direction is unknown, or the wind direction is from between 162° and 277°, THEN inform the NRC that the release may enter Canadian territory.

c. IF TEDE doses are::'.: 1,000 mrem or thyroid dose::'.: 5,000 mrem are projected beyond 10 miles, THEN coordinate with state and county officials to determine appropriate PAR.

d. IF an Initial PAR was to Shelter a Subarea(s), and consultation with the State and County Emergency Management Agencies determine that it is safe to do so, THEN change the PAR from Shelter to Evacuate.

3.1 ALARA -As Low As Reasonably Achievable, means making every reasonable effort to maintain exposure~ to radiation as far below the dose limits in 1 OCFR20 as is practical and consistent with the purpose for which the. licensed activity is undertaken.

3.2 .• COMMITTED DOSE EQUN ALENT (CDE) - The dose equivalent to organs or tissues that will be received from an intake of radioactive material by an individual during the 50-year period following the intake.

3.3 DADS -The Data Acquisition and Display System is a computerized system, which provides plant parameters, meteorology data, dose calculations, and other related programs.

3.4 EMERGENCY PLANNING ZONE (EPZ) -The two zones that are established around a nuclear power station in which predetermined protective actions plans are needed .

. , 3.4.1 The first zone has an approximate radius of 10 miles for the plume exposure

pathway.

3.4.2 The seyond zone mt~ an ~ppr,~ximate i;adius of 50 miles for the ingestion exposure pathway._

v ,f.,

3.5 EVACUATION DOSE - The dose that a potential evacuee would receive if he or she were . op1:,mly, exposed durii;ig the1 evap~atipn; :.. .

', ~ ,· ,' : . (,. :-:-: . 3.6 EVACUATION EXPOSURE PERIOD -The period during which those people being

evacuatyd are exposed to the. Bdioactive plume. .

3. 7 EXPOSURE TIME - That period of time during which the off site population will be exposed to radiation a~ a resllh of an airborne rad~oactive release.

3.8 . HOSTILE ACTION,7 An act.toward DBNPS or its personnel that includes the use of violent force to destroy yquipment,. take:HOS.TAGES, and/or intimidate the licensee to achieve an end. This includes attack by air, land, or water using guns, explosives, PROJECTILEs, vehicles, or other .devices used to deliver destructive force. Other acts that satisfy the overal} 1ntent· may be· included. HOSTILE ACTION should not be construed to include acts of civil disobedienc~ or felonio1:1s acts that are not part of a concerted attack on

DBNPS. Non-terrorism-based EALs should be used to address such activities (i.e., this may include violent acts between individuals in the OWNER CONTROLLED AREA.

KI FOR THE GENERAL PUBLIC - Recommending potassium iodide (KI) for the general public is the responsibility of the State of Ohio Department of Health. The station will recommend to the State administrating KI in accordance with State procedures upon declaration of a General Emergency.

KNOWN IMPEDIMENTS TO EVACUATION - Those conditions that may affect the ability to evacuate a large portion of the population within the Emergency Planning Zone (such as inclement weather, roadway/bridge damage following a natural event). State or

· counties must have provided prior knowledge of these impediments to the utility prior to the Protective Action decision-making.

LAKE BREEZE - A meteorological condition that may occur on clear, sunny days. During a lake breeze, a radioactive release can travel inland, rise, reverse course in an. overhead return flow, and then return to land in a convoluted path.

3.12 · MINIMUM RADIOACTNE RELEASE PROTECTNE ACTION• RECOMMENDATIONS (PAR)-At a minimum a PAR will be issued for Subarea 1, Subarea 12, and affected downwind subareas within five miles AND advise the general public to take KI in accordance with the Ohio Plan for Response to Radiation 'Emergencies at Licensed Nuclear Facilities.

3.13 MONITOR AND PREPARE- Guidance provided to the population within the Emergency

· Planning Zdne, typically for those Sheltering in Place. This 'advices the public to maintain an awareness of the event through media broadcasts and subsequent'Emergency Alert System messages. The public should make preparations for evacuation ( or other protective actions) as directed. ' .

OFFSITE - Any area outside the Owner Controlled Area surrounding Davis-Besse Nuclear Power Station. ·

RAPIDLY ESCALATING SEVERE ACCIDENT- This describes an accident in which there has beeh significant degradation: of the reactor core, and because of the accident, the integrity of Containment is challenged. It is postulated that this accident will result in a significant release of radioactive material and subsequent dose to the public.

3.19 SHELTERING-The use of a structure for radiation protection from an airborne phime and from deposited radioactive material. A wood frame home without a basement is the • assumed structure for sheltering in the Davis;..Besse EPZ.

3.20 SHORT-TERM (PUFF) RELEASE-A controlled venting ofradioac_tive gases (usually from Containment), sometimes referred to as a "puff' release. To be considered a shortterm release, jt must meet all of the following c:riteria:, • Initiated by the operator, not the accident. • P~rformed in a controlled manner and able to_ be secured, _if necessary • Monitored by effluent radiation monitors ( e.g:, Station Vent radiation monitors) • Short-teqn (:S 1 hour) . • Doses are less than'EP A guidance

3.21 TOTAL EFFECTIVE DOSE EQUIV AI,ENT (TEDE)-The sum of the deep-dose equivalent (foi; external exposure) ami'the Committed Effective Dose Equivalent (for internal exposure). · ·

.4.0 RESPONSIBILITIES

5.0

4.1 The Emergency Director is responsible for directing protective actions for Station _personnel and recommending protectiv~ actions to offsite officials for the Plume Exposure Pathway (10-mile EPZ). ·

4.2 The Dose Assessment Coordinator is responsible for collecting and analyzing offsite dose assessment data used to provide the basis for protective action recommendations.

. ' NOTE 6.2· ·


• ANY CONDITION THAT WSTIFIES ISSUING AN OFFSITE PROTECTIVE ACTION REQUIRES A GENERAL EMERGENCY ·DECLARATION. ·

• Offsite Protection Action Recommendations shall be made with initial notification of a General Emergency.

• . Davis~Besse will ~lways recoininend EVACUATION of Sub~ea 12 (Lake Erie) and when appropriate Subarea 10 (Wildlife area) due to lack of shelters in these areas.

• A SHELTERING PAR will NOT be issued for any subarea in which an EVACUATION PAR has already been recommended.

. . ! . . . . . .

6.2 Offsite Protective Actions

6.2.1 Refer to Attachment 1 to determine recommended Protective Action Recommendation.

·CAUTION 6.2.2 Protective Action Recommendations once issued start in motion a sequence of events in the 10-mile emergency planning zone that, if modified, have the potential to cause confusion that may hamper the orderly implementation of protective actions for the general public.

6.2.2 . Notify offsite agencies and the NRC of the PARs and the affected subareas using RAEP-02110, Emergency Notification, and Initial Notification Form, DBEP-010.

a. IF these are revised P ARs THEN DO NOT downgrade a previously issued PAR for a specific subarea until the conditions that caused the PAR.to be issued are fully under control. The new PAR should include those subareas that were previously evacuated or sheltered and any new subareas.

b. IF a lake breeze is occurring, the wind direction is unknown, or the wind direction is from between 162° and 277°,

. THEN inform the NRC that the release may enter Canadian territory.

c. IF TEDE doses are::::: 1,000 mrem or thyroid dose::::: 5,000 mrem are projected beyond 10 miles, ( THEN coordinate with state and county officials to determine appropriate PAR.

d. IF an Initial PAR was to Shelter a Subarea(s), and consultation with the State and County Emergency Management Agencies determine that it is safe to do so, THEN change the PAR from Shelter to Evacuate.
