VY-RAI-01 Please provide a section cross-reference between the Vermont Yankee Nuclear Power Station (VY) PDEP and NUREG-0654/FEMA-REP-1 to assist the U.S. Nuclear Regulatory Commission (NRC) staff in verifying that applicable evaluation criteria are consistent with proposed exemptions.
Response The following table provides a cross-reference of NUREG-0654/FEMA-REP-1, as well as the 10 CFR 50.47(b) Planning Standards, Appendix E.IV Planning Requirements to the applicable VY PDEP sections.NUREG-0654,Section II Planning Standard Planning Requirement VY PDEP Evaluation Criteria (10 CFR 50.47)** (Appendix E.IV)** Section 7.0 8.0 A (b)(1) A.1,2, 4,7 8.8.1.1 Figure 8.1 8.0 8.1 8.1.1 8.2 B (b)(2) A.1, 2,4,9; C.1 8.8.3 Table 8.1 10.4 Appendix D 3.7 8.1.1 C (b)(3) A.6, 7 8.2.3 Appendix C Appendix D BVY 15-009 / Attachment 1/ Page 2 of 24 NUREG-0654,Section II Planning Standard Planning Requirement VY PDEP Evaluation Criteria (10 CFR 50.47)** (Appendix E.IV)** Section 5.0 D (b)(4) B.1,2; C.1,2 5.0____ ___ ___ ___ _ _ ___ ___ ___ ___ ___ ___ ___ Appendix A 8.3 9.0 9.2 E (b)(5) A.6, 7; C.1,2; D.1, 3; E Table 9.1 11.1 Appendix D Appendix E 7.0 Table 7.1 F (b)(6) C.1; D.1, 3; E 9.2 Figure 9.1 12.1.2 G (b)(7) A.7; D.2 11.2 6.1 6.2 8.2 H (b)(8) E; G 9.2 12.4 Appendix B 6.2.5 1 (b)(9) A.4; B.1; C.2; E 10.0 Appendix A J (b)(10) C.1; E; 1 10.3 10.2 K (b)(11) E 10.3 10.4 Table 8.1 L (b)(12) A.6, 7; E 10.2 10.4 M (b)(13) H 8.2.4 N (b)(14) E9; F 12.1 Table 8.1 0 (b)(15) F 10.4 12.0 BVY 15-009 / Attachment 1/ Page 3 of 24 NUREG-0654,Section II Planning Standard Planning Requirement VY PDEP Evaluation Criteria (10 CFR 50.47)** (Appendix E.IV)** Section Table of Contents P (b)(16) G 12.0 Appendix E as exempted The above table has been added to the Permanently Defueled Emergency Plan (PDEP) as Appendix F. Attachment 2 of this response provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the addition of the above table as Appendix F.VY-RAI-02 Section 1.0, "Introduction" of the PDEP inaccurately states, "The analysis of the potential radiological impact of an accident in a permanently defueled condition Indicates that any[italics added] releases beyond the Site Boundary are below the Environmental Protection Agency's (EPA's) Protective Action Guide (PAG) exposure levels...." Please clarify that this statement applies to site-specific analyses provided for applicable"design-basis-accidents" not exceeding EPA PAGs at the site boundary, or provide technical justification that a spent fuel fire, if it were to occur, would not exceed EPA PAGs at the site boundary.
While unlikely, consideration is still given as an exemption for the possibility of a spent fuel fire that offsite government officials may determine warrants implementation of a protective action for the public in the vicinity of the VY facility.In addition, Section 1.2, "Scope" inaccurately states, "Because there are no postulated accidents that would result in dose consequences that are large enough to require offsite emergency planning..." Please clarify that site-specific analyses are provided for applicable "design-basis-accidents" not exceeding EPA PAGs at the site boundary and whether comprehensive (all hazards) emergency management planning may be used by offsite government officials to implement protective measures for the public as deemed warranted.
Response The statement concerning the analysis of the potential radiological impact of an "accident" in Section 1.0 is meant to apply to "design basis" accidents only. Similarly, the statement included in Section 1.2 of the PDEP is intended to apply to postulated "design basis" accidents.
In addition, the analyses show that after the spent fuel has decayed for 15.4 months, for beyond-design-basis events related to the spent fuel pool, the analyzed event is either not credible;sufficient time is available to take mitigative actions or, if needed, offsite protective actions using an all-hazards approach; or the radiological consequences of the event will not exceed the limits of the EPA PAGs at the exclusion area boundary.To ensure clarity, the statements in Sections 1.0 and 1.2 of the PDEP have been revised to include the phrase "design basis accidents." Section 1.2 is also revised to state that an all BVY 15-009 / Attachment 1 / Page 4 of 24 hazards approach to emergency planning may be used by government officials to implement protective measures for the public as deemed appropriate.
Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the revisions to Sections 1.0 and 1.2, described above.VY-RAI-03 VY's current Emergency Plan provides the following information in Section 3.5, "State Government Notification and Response":
Vermont Yankee is responsible for conveying specific accident information, radiological assessment information, and protective action recommendations to the State of Vermont, State of New Hampshire, and Commonwealth of Massachusetts.
VY exemption request, dated March 14, 2014 (ADAMS Accession No. ML14080A141) requested the following:
E.9.a. Provision for communications with contiguous
[italics added]Stateflocal governments w-ithin than plume oxposuro pathway EPZ. Such communications shall be tested monthly.Sections 3.1, "Overview of Permanently Defueled Emergency Plan" and 3.6, "State and Local Government Notification and Response" of the PDEP provide no reference to interfaces with the State of New Hampshire and the Commonwealth of Massachusetts.
Please provide documentation that the State of New Hampshire and the Commonwealth of Massachusetts have agreed that they no longer require notification from the VY in the event of a declared emergency or revise to address these notifications.
Notification of other contiguous States also needs to be addressed in Section 3.3(5) and Figure 9.1,"Notification Plan" of the PDEP.Response As states that are contiguous to the VY site, VY will maintain the capability to communicate with, and notify the state emergency management agencies of Vermont and New Hampshire of an emergency declaration.
Additionally, as a noncontiguous state, VY will maintain the capability to communicate with, and notify, the Commonwealth of Massachusetts of an emergency declaration because of its proximity to the VY site. As described in Sections 3.6 and 7.1 of the PDEP, VY maintains the capability to communicate with the state emergency management agencies on a 24-hour basis and convey specific accident information using the InForm Notification System (InForm).
As a backup to InForm, the commercial telephone can be used to notify the State Police of Vermont, New Hampshire and Massachusetts of any emergency.
Sections 7.1, 7.2 and 12.1.2 of the PDEP describe the monthly tests of the communications channels between VY and the states.Sections 3.1, 3.3 (Item #5). 3.6, 5.2, 5.3, 7.1, 7.2, 8.1.1 (Item #1), 8.3, 9.2.1 (Item #3), 11.1, 12.1.2, Table 7.1, Figure 9.1 and Appendix D (Letters of Agreement) of the PDEP have been revised to address the capability to communicate with and notify New Hampshire and Massachusetts of an emergency declaration.
BVY 15-009 / Attachment 1/ Page 5 of 24 Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the revisions to the sections described above.VY-RAI-04 Section 3.1 (3 rd paragraph) inaccurately states, "Because there are not postulated accidents that would result in off-site dose consequences large enough to require off-site emergency planning..." The NRC's evaluation of requested exemptions can consider credit for comprehensive (all hazards) emergency management planning, if needed, for an unlikely spent fuel fire or at the judgment of offsite government officials.
Elimination of the Site Area and General Emergency classifications is based on analyses of applicable design-basis-accidents.
Please revise accordingly to reflect that the capability exists to implement offsite protective action for the public, if needed, based on the judgment of offsite government officials using comprehensive (all hazards)emergency management planning.Additionally, in the unlikely event that there is a catastrophic loss of spent fuel pool (SFP) water inventory, there is a potential for an offsite release of radioactive material, although they may be a small fraction of the EPA PAG. Please provide further discussion on how the interfaces with State and local government agencies would be performed to support an offsite protective action decision, if deemed appropriate by respective government authority.
Response The statement included in Section 3.1 of the PDEP is intended to apply to postulated "design basis" accidents.
In addition, the analyses show that after the spent fuel has decayed for 15.4 months, for beyond-design-basis events related to the spent fuel pool, the analyzed event is either not credible; sufficient time is available to take mitigative actions or, if needed, offsite protective actions using an all-hazards approach; or the radiological consequences of the event will not exceed the limits of the EPA PAGs at the exclusion area boundary.To ensure clarity, the statement in Section 3.1 of the PDEP has been revised to include the phrase "design basis accidents." Section 3.1 is also revised to state that an all hazards approach to emergency planning may be used by government officials to implement protective measures for the public as deemed appropriate.
Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the revisions to Section 3.1, described above.In the unlikely event that there is a catastrophic loss of SFP water inventory VY maintains the capability to communicate with the state emergency management agencies on a 24-hour basis and convey specific accident information using the InForm Notification System (InForm).
As a backup to InForm, the commercial telephone can be used to notify offsite authorities of any emergency.
As described in Section 11.1 of the PDEP, notification is made within 60 minutes of emergency declaration or change in classification.
Due to the slow rate of the postulated event scenarios and the absence of immediate actions necessary to protect the public health and safety, the notification time of 60 minutes is appropriate.
In the permanently defueled condition, notification to offsite authorities will continue to include the classification of an emergency, the impact of a potential release of radioactive materials and sufficient information to support an BVY 15-009 / Attachment 1/ Page 6 of 24 offsite protective action decision utilizing an all hazards approach to emergency planning, if deemed appropriate by respective government authorities.
VY-RAI-05 Section 3.8, "Technical Support" of the PDEP states (in part), "augmentation.. .can be requested from various contractors." Please specify what functions are relied on in the PDEP for contractor support and identify whether contracts or letters of agreement are in-place with these contract organizations for response during an emergency at the VY facility.Response VY does not rely upon contractor support to implement the PDEP. Thus, there are no contracts or letters of agreement in place with any contract organizations to provide personnel to respond to an event requiring implementation of the VY Emergency Plan. However, if an emergency exceeds the capabilities of the VY emergency organization, additional resources are available within the Entergy fleet. Additional expertise could also be requested through a variety of contractors and private sector support organizations.
However, the necessary expertise would be dependent on the specific nature of the emergency and cannot be determined in advance.VY-RAI-06 Please provide an estimate of the time frame required to implement the SFP mitigation strategies outlined in Section 3.9 "Mitigation of Consequences of Beyond Design Basis Events" using designated on-shift personnel trained and available to perform these actions.Response See response to RAI-16.VY-RAI-07 NRC evaluation of exemption request in SECY-14-0066 considered that in the unlikely event of a beyond design-basis-accident, resulting in a radiological release due to a postulated zirconium fire, early offsite protective measures could be implemented.
Section IV.B.1 to Appendix E of Part 50 still requires that the licensee have the means to determine the magnitude of, and for continually assessing the impact of, a release of radioactive materials.
However, no reference to any type of dose assessment is provided in Section 6.0, "Emergency Response Facilities and Equipment" of the PDEP. Please describe in Section 6.0 of the PDEP on how VY addresses the capabilities to perform dose assessment to assess the magnitude of a potential radiological release.Response VY maintains and operates on-site monitoring systems needed to provide data that is essential for initiating emergency measures and performing accident assessment.
This includes monitoring systems for plant processes, radiological conditions, meteorological conditions, and fire hazards. The essential monitoring systems are incorporated in the EALs referenced in BVY 15-009 / Attachment 1/ Page 7 of 24 Appendix A of the PDEP. In addition to installed monitoring systems, VY has augmented onsite radiological assessment capability, including portable radiation and contamination monitoring instruments and sampling equipment.
Section 6.1 of the PDEP states that the Control Room is where plant systems and equipment parameters are monitored.
Control Room personnel assess plant conditions, evaluate the magnitude and potential consequences of abnormal conditions, initiate preventative, mitigating and corrective actions and perform notifications.
Sections 6.2 and 6.2.2 of the PDEP have been revised to address the capability to perform dose assessment and to assess the magnitude of a potential radiological release. Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the revisions to Sections 6.2 and 6.2.2.VY-RAI-08 Section 6.2.1, "Process Monitors" of the PDEP states, "Annunciator and computer alarms are provided for a variety of parameters including SFP cooling to indicate SFP level, temperature and pump status." Please clarify what specific parameters reflecting SFP cooling and level status will continue to be available in the Control Room in support of prompt classification and implementation of mitigation measures, if needed.Response The SFP pumps are monitored in the Control Room and locally near the equipment.
Control Room indication includes direct SFP temperature, fuel pool water temperature out of the heat exchangers (taken downstream of the pumps), pump run lights, pump discharge pressures, service water flow, Station Service Water System (SWS) to the Standby Fuel Pool Cooling Subsystem (SFPCS) heat exchanger discharge pressure and valve position lights. Local indication includes SFP water temperature into the heat exchangers, pump suction and discharge pressures, and heat exchanger discharge pressure.There are two narrow range channels of continuous remote indication of spent fuel pool water level in the control room. Each of these channels provides high and low annunciation on the Fuel Pool Filter Demineralizer Panel with a system trouble alarm and high and low level indicator lights in the Control Room. In addition, each of these channels provides input to the plant computer and there is local water level indication on the side of the SFP.There are two channels of continuous remote indication of the spent fuel pool water temperature in the Control Room. There are two channels of SFP water temperature to a common recorder that provides high temperature annunciation in the Control Room. In addition, there are two channels of SFP water temperature that provide input to the plant computer.There are two channels of continuous remote indication of Refueling Floor area radiation in the Control Room. Each of these channels provide high area radiation annunciation in the Control Room. A local alarm to notify personnel of high area radiation levels is also in place. In addition, each of these channels provides input to the plant computer.The manner in which process monitors are used for accident recognition and classification is provided in EALs referenced in Appendix A of the PDEP.
BVY 15-009 / Attachment 1/ Page 8 of 24 VY-RAI-9 Clarify whether meteorological parameters, discussed in Section 6.2.1 "Meteorological Capability" of the PDEP, are available in the Control Room and are adequate to support dose assessment activities.
Response Meteorological data is displayed in the Control Room and is adequate to determine the projected radiological conditions in the event of an accidental release of radioactivity to the environment.
Section 6.2.3, "Meteorological Capability" of the PDEP has been revised to indicate that the meteorological data is available in the Control Room and is used to determine the projected radiological conditions in the event of an accidental release of radioactivity to the environment.
VY has no plans to modify or alter data currently provided to the Control Room to support dose assessment activities.
Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the revisions to Section 6.2.3.VY-RAI-10 Section 7.3, "Emergency Response Organization
[ERO] Notification System" of the PDEP identifies the ERO Notification System as the primary means of activating the ERO upon declaration of an emergency, but provides no description of system capabilities.
Please describe the capabilities and communications methods used by the ERO Notification Systems to provide for the timely notification and augmentation of ERO personnel.
Response On-site staff are informed of an emergency condition through the use of the plant public address system and/or office telephone and/or wireless devices capable of receiving telephone calls and/or text messages.
In the event that personnel required to staff emergency positions are not on-site at the time an emergency is declared, they may be contacted by commercial telephone including land lines and/or wireless devices capable of receiving telephone calls and text messages.
Mobilization of the ERO will be conducted under the direction of the Emergency Director, according to personnel assignments and telephone numbers maintained in various telephone directories.
The system is tested as described in Section 12.1.2 of the PDEP.Sections 3.5 and 7.3 of the PDEP have been revised to address the capabilities and communications methods used to perform timely notification and augmentation of ERO personnel.
Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the revisions to Sections 3.5 and 7.3.
BVY 15-009 / Attachment 1/ Page 9 of 24 VY-RAI-1 1 Table 7.1, "Vermont Yankee Emergency Communication Matrix" of the PDEP provides reference to the Southwest Fire Radio. Is this radio tested on a set frequency similar to all of the other communications devices, as listed in Section 12.1.2, "Communications Tests"? In addition, please clarify why the Southwest Fire Radio is not described in Section 7.0, "Communications", but is listed on Table 7.1 as a backup means of communication with the State Emergency Operations Centers.Response VY maintains a multi-channel radio, referred to as the Mutual Aid Radio, in the Control Room that can be utilized to contact the Southwest Mutual Aid; Rescue, Inc.; Brattleboro Memorial Hospital and the State EOCs in the event that all other offsite channels of communication fail.The Southwest Fire Radio is not a stand-alone system, but is a single channel on the Mutual Aid Radio. The Southwest Fire Radio is tested on a monthly basis.Section 7.8 has been added to the PDEP to address the Mutual Aid Radio. Table 7.1 has been revised to indicate that the Mutual Aid Radio serves as a means to communicate with the State EOCs. Section 12.1.2 of the PDEP has not been revised to address periodic testing of the Mutual Aid Radio because the system is a communication channel with the state government of New Hampshire and is addressed in Item 1 of Section 12.1.2. Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the addition of Section 7.8 and change to Table 7.1.VY-RAI-12 Please describe the alternate external telephone line arrangement, described in Section 7.7, "Commercial Telephone System" of the PDEP, to address telephone equipment blockage in the local area. Is this referring to "microwave" communications listed In Section 7.8, "Emergency Power Supply for Communications"?
Response The alternate external telephone line arrangement consists of two distinct paths from the plant to the telephone company Central Office (CO) with no single failure point that would result in a loss of capability of the system. Additionally, Internet Protocol (IP) telephones are installed to provide additional diversity when added to the CO and Private Branch Exchange (PBX)telephones.
The alternate telephone line arrangement described in Section 7.7 of the PDEP does not refer to the "microwave" communication system. VY currently utilizes the microwave system to notify system load dispatchers of emergency conditions at the plant. In a permanently shutdown and defueled condition, VY will no longer supply electricity to the grid and there is no need to contact system load dispatchers to notify them of potential disruptions to the electricity supply. This communication system is not included in the PDEP and reference to "microwave" in Section 7.9 (as revised) of the PDEP has been replaced with "IP" to indicate that the IP telephones are provided with a redundant power supply.
BVY 15-009 / Attachment 1/ Page 10 of 24 Section 7.9 has been revised to replace "microwave" with 113" in accordance with this response.Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the change to Section 7.9.VY-RAI-13 Section 7.8 of the PDEP states, "All emergency communications (including all phones)located within the plant are connected to an emergency or redundant supply. Please describe the power source and duration for these emergency or redundant supplies.Response As a backup to the normal offsite power supply, a feed from the Vernon Hydroelectric Station can also be used as an additional source of backup power. Power can be provided to the station, including communication systems, using the Station Blackout (SBO) Diesel Generator (DG). The SBO DG has a dedicated fuel oil storage tank with a capacity sufficient for operation of the SBO DG at 100% rated load for at least 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.VY-RAI-14 Plan objective
- 5, listed In Section 3.2, "Objectives" of the PDEP, is to "establish an engineering support organization to aid the plant personnel in limiting the consequences of and recovery from an event." However, this is not addressed in Section 8.2,"Emergency Response Organization", or specifically Section 8.2.4, "Recovery Organization" of the PDEP. Please describe how this plan objective is under the PDEP.Response During an emergency, engineering personnel would focus on plant assessment and provide technical support to the ERO as requested by the Technical Coordinator.
To clarify how plan objective
- 5 is met, Section 8.2.1 of the PDEP has been revised to address engineering support to the Technical Coordinator for plant assessment and technical support.Sections 8.2 and 8.2.1 of the PDEP have been revised to address plan objective
- 5. Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the revisions to Sections 8.2 and 8.2.1.With respect to engineering support provided to the Recovery Organization, as described in Section 8.2.4 of the PDEP, planning for the recovery mode of operations involves the development of an organizational capability that can be adapted to any emergency situation.
The Emergency Director utilizes the normal plant and emergency organizations described in Sections 8.1 and 8.2 of the PDEP to staff the recovery organization and provide the radiological and technical expertise required to restore the plant to normal conditions.
VY-RAI-15 Section 8.2.4 of the PDEP provides a general overview of recovery expectations.
Please describe the position/title, authority and responsibilities of individuals who will fill key positions in the facility recovery organization, including technical personnel with responsibilities to develop, evaluate and direct recovery and reentry operations, consistent with NUREG-0654/FEMA-REP-1 Evaluation Criterion M.2.
BVY 15-009 / Attachment 1/ Page 11 of 24 Response As described in Section 8.2.4 of the PDEP, planning for the recovery mode of operations involves the development of an organizational capability that can be adapted to any emergency situation.
In a permanently shutdown and defueled condition, the only key position identified in the recovery organization is the Emergency Director.
Upon termination of an emergency and transition into the recovery phase, the Emergency Director assembles the recovery organization to address the specific emergency circumstances of the terminated event. The Emergency Director is responsible for: " Ensuring VY is maintained in a safe condition;
- Managing onsite recovery activities during the initial recovery phase;* Keeping corporate support apprised of VY activities and requirements.
The Emergency Director utilizes the normal plant and emergency organizations described in Sections 8.1 and 8.2 of the PDEP to staff the recovery organization and provide the radiological and technical expertise required to restore the plant to normal conditions.
VY-RAI-16 In reference to Table 8.1, "Minimum On-Shift and Staffing Requirements" of the PDEP, please response to the following:
- a. Has VY performed an on-shift analysis for ERO functions to ensure sufficient personnel will be able to respond to the limiting event, which is a catastrophic loss of SFP water inventory, using the minimum shift staffing as indicated in the Table 8.1, to verify that a SFP mitigation strategy can be promptly implemented using available on-shift personnel?
The response should include:* SFP mitigation strategies as described in Section 3.9 of the PDEP, and* All functional areas of the Table B-1 to address any potential collateral duties.Additionally, provide an update to Table 8.1 reflecting the on-shift personnel required to perform mitigation strategies for a catastrophic loss of SFP inventory.
Response An analysis of the time frame required to implement the SFP mitigation strategies outlined in Section 3.9 of the PDEP has been performed and indicates that the strategies can be implemented using the on-shift staffing complement (Shift Manager/Emergency Director, Non-certified Operator (NCO) and Radiation Protection Technician (RPT)) within two hours and without impacting the ability to meet all of the major functional areas of Table B-1 in NUREG-0654/FEMA-REP-1.
The two hour time frame is based on Performance Attribute 11 in Section 2.3.1, SFP Makeup Capability, of NEI 06-12, B.5.b Phase 2 & 3 Submittal Guideline (Reference 2): The system should be capable of being deployed within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> from the time plant personnel diagnose that external SFP makeup is required.
BVY 15-009 / Attachment 1/ Page 12 of 24 The specific event scenario utilized for this analysis involves a catastrophic loss of SFP level.The analysis of the time to initiate SFP mitigation strategies is based on the expected system configurations at the time the PDEP will be implemented (April 2016) and assumes that an engineering change has been completed to permanently relocate the B.5.b pump closer to its water source at the cooling tower deep basin and permanently makeup the associated suction and discharge hoses to reduce the time to implement.
This engineering change is scheduled to be completed prior to the end of 2015. It is further assumed that the intake structure and the fire protection system in the Turbine Building (TB) and/or Reactor Building (RB) is damaged which requires those structures to be isolated to support pressurizing the fire header successfully.
The Shift Manager retains the responsibility to make emergency classifications, notify the State and NRC, and activate the ERO in a timely manner, and is not distracted from emergency event oversight, including ERO leadership responsibilities.
The Shift Manager is capable of assessing, classifying and declaring an emergency condition within 30 minutes, notifying the states of Vermont, New Hampshire and Massachusetts within 60 minutes of emergency declaration and making notifications to the ERO of the need to augment.It is reasonable to expect that mitigating actions required to address a catastrophic loss of SFP can be performed using an on-shift RPT because credit is taken for existing area radiation monitors and associated alarms and NCOs are trained to self-monitor using radiation dose rate meters. In extreme conditions, the Radiation Protection Director would be responding within the required ERO two hour response time to assist in final implementation of the mitigating actions.The demonstration was performed on November 8, 2014. Calibrated stop watches were utilized to time the actions. Operators were stationed in the Auxiliary Operator break room. This location yields the longest time to reach the B.5.b storage shed to assemble/obtain the required equipment.
The external SFP strategy was used (PP 7019, Appendix G, Attachments 1, 2, 2A and 16) for the demonstration because it is considered the longest to implement.
The following results (times are identified in minutes) were obtained: T=0: Start. The NCO and RPT start from the Administration Building.
If they were to start from the Plant Support Building (PSB), then the time to obtain the required hoses, fittings and tools would be reduced accordingly.
It is assumed the NCO and RPT would discuss the required actions to coordinate their response.T=1 2: Time for the NCO/RPT to reach the B.5.b shed, obtain the required gear and return to Security Gatehouse
- 2. It is assumed that the Shift Manager would contact the Lead Security Shift Supervisor and request their support getting the gear through the gate house to reduce the delay. Security would work out the quickest means to support to minimize the delay.Upon entering the protected area, the NCO and RPT would separate to perform the following tasks concurrently:
RPT: T=24: Time after entering the Protected Area (PA) to make the required connections from the fire hydrant on the west side of the Containment Access Building (FH-2) to the RB penetration (SB-1 00-5 or 6). It is assumed that this task takes 12 minutes to account for handling of the hoses, tools and fittings by a person who will be new to handling fire equipment at the start of SAFSTOR. The time to accomplish is based on operator experience for operating the valves.
BVY 15-009 / Attachment 1/ Page 13 ot 24 T=39: Time to rotate the inside RB penetration (SB-100-5(6))
out of the way (assume 15 minutes per flange) (includes travel from outside to inside RB).T=59: Time to isolate the intake structure and TB/RB from the outer Fire Protection loop. A conservative estimate of 5 minutes per valve is utilized.
For this scenario, it is assumed that four (4) valves would need to be isolated.T=74: Time to rotate the outside RB penetration and make the final connection of the hoses. It is expected that the NCO and RPT would coordinate their actions to aid in making the connections.
Straps are available inside and out to hold the hose to the penetration.
T=84: Time after making the final connections of the inside and outside fire hoses, the valves on FH-2 would start being throttled open to commence making up water to the fuel pool.NCO: T=42: Time to complete routing the hose from the RB 345 foot elevation to the 252 foot elevation including attaching the SFP diffuser to the fuel pool railing and installing straps to hold the fire hoses in place. It is assumed to take 30 minutes to be conservative based on the actual recorded time of 26 minutes 58 seconds for the single operator to complete.T=57: Time for the NCO to walk from the RB to the pump at the West Cooling Tower. Timing was performed utilizing the several paths possible to the location the B.5.b pump will be located.The time to walk through the West Security Owner Controlled Area access building and around the West Cooling Tower was 10 minutes 44 seconds. To be conservative, it is assumed to take 15 minutes to account for uncertainties based on weather/plant conditions.
T=69: Time for the NCO to start the pump once any leaks in the fire header have been isolated.Per the guideline, the pump would not be started until the header is isolated so that will coincide with the RPT isolating the header at T=59 minutes.Summary Successful implementation of the mitigating strategy was achieved within 84 minutes utilizing only the on-shift staffing (Shift Manager, NCO and RPT) required by the proposed PDEP currently undergoing NRC review. Specifically, the PDEP minimum on-shift staff is tasked with implementation of the mitigating strategy.
The Shift Manager retains the responsibility to implement the emergency plan. The NCO and RPT are capable of performing the actions necessary to implement the mitigation strategy without the need to mobilize off-site resources or the utilization of other on-shift personnel.
Table 8.1 of the PDEP has been revised to reflect the positions performing the mitigating strategy.Section 3.9 of the PDEP has been revised to correct the reference to the mitigation strategies order, EA-02-026.
BVY 15-009 / Attachment 1/ Page 14 of 24 VY-RAI-17 Sections 5.0, "Emergency Classification System" and 9.1, "Emergency Condition Recognition and Classification" of the PDEP state (in part), "VY maintains the capability to assess, classify, and declare an emergency condition in accordance with site procedures
....." Please identify a specific time frame, and supporting technical justification, where VY will maintain the capability required for the prompt classification of an emergency condition, based on the permanent shutdown and defueled condition of the facility, or provide a copy of the site procedure that provides this information?
Response The emergency classification levels that will be applicable at VY, in order of increasing severity, are a Notification of Unusual Event and Alert. Each of these emergency classes requires notification to offsite agencies, as designated in the PDEP, as well as to the NRC. The classification of emergencies up to an Alert is consistent with the regulations for an ISFSI in 10 CFR 72.32(a)(3) and the exemptions proposed in Reference 1.VY will maintain the capability to assess, classify, and' declare an emergency condition within 30 minutes after the availability of indications to plant operators that an emergency action level threshold has been reached. In the permanently defueled condition, the rapidly developing scenarios associated with events initiated during reactor power operation are no longer credible.The consequences resulting from the only remaining events (e.g., fuel handling accident)develop over a significantly longer period. The 30 minute classification time frame is consistent with that approved for Kewaunee Power Station (Reference 3). Section 9.1 of the PDEP has been revised to include the 30 minute time frame.VY-RAI-18 Section 10.1.1, "Initial Radiological Dose Projection" of the PDEP provides that VY has developed a method to quickly determine the projected radiological conditions at the site boundary.
Please provide further information on how this dose projection is performed using on-shift staffing identified in Table 8.1, and include a copy of the applicable implementing procedure.
Response During the initial stages of an emergency, the Shift Manager, or an individual designated by the Shift Manager, is responsible to perform the initial evaluation of radiological conditions.
This activity is identified as a responsibility of the Shift Manager in Section 8.1.1 of the PDEP.Additionally, the on-shift staffing includes a Radiation Protection Technician.
With VY permanently shutdown, the only design basis accident scenario will be a fuel handling accident (FHA) in the SFP and the predominant isotope that will be released from a FHA is Kr-85. It is no longer necessary to maintain a sophisticated dose assessment capability with associated hardware, software and training appropriate for an operating nuclear power plant and a simplified manual method can provide an effective replacement dose assessment capability.
Conceptually, the method used to predict a Site Boundary dose from a FHA in the SFP area is to multiply a radiation monitor reading by a dose conversion factor based on wind speed and stability class. VY currently maintains a manual method to evaluate off-site radiological conditions.
Specific procedures supporting the PDEP, including the procedure BVY 15-009 / Attachment 1/ Page 15 of 24 associated with Initial Radiological Dose Projection, have not yet been developed.
The procedure will be developed considering that after permanent shutdown and removal of fuel from the reactor, the only viable accident scenario is a FHA in the SFP and will be provided to the NRC in a supplemental response by June 30, 2015.VY-RAI-19 Section 10.3.1, "Site Personnel Accountability" of the PDEP provides that the goal of the personnel accountability process is to account for personnel at an Alert declaration.
Please clarify in the PDEP how the following NUREG-0654/FEMA-REP-1 evaluation criterion is addressed or provide justification for why criteria are no longer considered applicable:
[J.5] Each licensee shall provide for a capability to account for all individuals onsite at the time of the emergency and ascertain the names of missing individuals within 60 minutes of the start of an emergency and account for all onsite individuals continuously thereafter, In addition, describe the communication means intended to notify site personnel of accountability, since Section 7.5 of the PDEP only identifies that the Plant Intercom System is located in "many areas" throughout the plant.Response Upon declaration of an emergency, Control Room personnel announce the emergency classification over the plant page system. As described in Section 7.5 of the PDEP, during emergency situations, the system is used as the primary means for notifying plant personnel of the emergency and calling for any missing or unaccounted for personnel that may be in the plant. In a permanently shutdown and defueled condition, the inability to communicate with plant personnel because of noise is no longer a significant issue. The use of the plant page system, supplemented by Security sweeps as described below, is appropriate to notify plant personnel of an emergency declaration.
In accordance with site procedures, following announcement of an emergency classification, plant personnel are responsible for reporting to designated areas and aiding Security in the accountability process. The emergency classification announcement prompts Security to print a report detailing the locations of on-site personnel.
If personnel are not accounted for, the Control Room is notified and announcements are made using the plant page system. If personnel are still unaccounted for following announcements, Security will initiate sweeps to locate the missing individuals.
Section 10.3.1 has been revised to indicate that the goal of the personnel accountability process is to account for personnel within 60 minutes of an Alert declaration.
Section 10.3.1 has also been revised to indicate that plant personnel are responsible for reporting to designated areas following announcement of an emergency classification; the Control Room will initiate announcements using the plant page system if personnel are unaccounted for; and if personnel are still unaccounted for following Control Room announcements, then Security will initiate sweeps to locate the missing individuals.
Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the addition of Section 10.3.1.
BVY 15-009 / Attachment 1/ Page 16 of 24 VY-RAI-20 Section 10.3.3, "Decontamination Capability" of the PDEP is limited to a general discussion of personnel monitoring and decontamination.
Please describe how, or where, NUREG-0654/FEMA-REP-1 Evaluation Criteria K.5.a and K.6 are addressed for decontamination and on-site contamination control.Response Evaluation Criteria K.5.a requires the emergency plan to address action levels for determining the need for decontamination.
During emergency conditions, VY maintains normal plant decontamination and contamination control measures as closely as possible.
However, these measures may be modified by the Emergency Director should conditions warrant.Evaluation Criteria K.6 requires licensees to provide contamination control measures with respect to area access control, drinking water and food supplies and the return of areas and items to normal use. VY isolates and restricts the use of contaminated areas; monitors personnel leaving contaminated areas; controls access to potentially contaminated drinking water and food supplies; makes arrangements for transport of non-contaminated off-site supplies if the potential exists for contamination of on-site food or drinking water supplies that renders these supplies non-consumable; and restricts areas and contaminated items from returning to normal use until conduct of appropriate surveys and verification that the contamination levels are acceptable.
Section 10.3.3 of the PDEP has been revised to reflect standard station protocol described above. Additionally, the title of Section 10.3.3 has been revised to Contamination Control and Decontamination Capability to reflect the changes. Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the revisions to Section 10.3.3.VY-RAI-21 Section 10.4.1, "Medical Treatment" of the PDEP provides that initial on-site medical treatment is provided by on-site personnel.
Please provide further information on who these personnel are (e.g., on-shift, duty performed as a collateral function), and what level and frequency of training are they giving.Response Upon implementation of the PDEP, rescue and first aid treatment will be provided by two qualified, on-shift personnel (Control Room staff or other qualified personnel).
The members assigned rescue/first aid treatment duties will attend to normal plant duties until notified of an incident requiring a first-aid response.
Individual responsibilities then immediately change to the higher priority role. The health and safety of personnel take precedence over other normally assigned responsibilities.
Rescue/first aid duties of on-shift staff do not create a conflict between their normal and emergency duties.NUREG-0654/FEMA-REP-1, Revision 1, Evaluation Criterion 11.0.3 establishes guidance for use of Red Cross Multi-Media Training for individuals assigned to licensee first aid teams. This guidance was published in 1980. In the interim, Red Cross Multi-Media Training has been superseded by other courses. Because the suggested Red Cross Multi-Media course no longer BVY 15-009 / Attachment 1/ Page 17 of 24 exists, VY is unable to provide a direct correlation between its own training program and the Red Cross Multi-Media training course. However, VY notes that the Red Cross Multi-Media training program was intended to train a layperson to recognize simple first aid situations and provide minimal first aid care until the arrival of a professional medical response team. The Red Cross Multi-Media training course was an 8 to 16 hour1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> program. VY personnel who will be qualified to provide initial on-site medical treatment will, at a minimum, complete an 8-hour program based on the American Heart Association First Aid/CPR/AED course to meet the educational and examination requirements of its Basic First Aid and CPRIAED courses. The course provides critical skills needed to respond to and manage a first aid, choking or sudden cardiac arrest emergency in the first few minutes until emergency medical services (EMS)arrives. Students learn skills such as how to treat bleeding, sprains, broken bones, shock and other first aid emergencies.
This course also teaches adult CPR and AED use. Therefore, the content of the training course meets or exceeds the requirements of the superseded Red Cross Multi-Media training course identified in NUREG-0654-FEMA-REP-1.
Recertification of the members assigned rescue/first aid treatment duties will be conducted as required by the level of certification held by the individual.
Section 12.1.5 of the PDEP, specifies the frequency of medical drills that evaluate the training of the medical response provided by on-site personnel.
VY-RAI-22 Section 10.5, "Protective Actions for Onsite Personnel" of the PDEP states, "A range of protective actions to protect onsite personnel and how they will ensure continued ability to perform the functions of the emergency plan." Please describe this intended range of protective actions to protect onsite personnel and how they will ensure continued ability to perform the functions of the emergency plan, or provide reference to and a copy of applicable implementing procedure.
Response Protective actions for onsite personnel are addressed in Sections 10.2 through 10.4 of the PDEP consistent with the applicable guidance providing the Planning Standard J of NUREG-0654-FEMA-REP-1.
Section 10.2 of the PDEP describes measures to be taken to control radiation exposure for the VY ERO and augmented personnel.
These measures include emergency kits with self-reading dosimeters and maintenance of dose records. Section 10.3.4 of the PDEP addresses the use of plant supplied radiation protection equipment and gear to support the emergency response effort, including respiratory protection and protective clothing assigned to ERO members.Additionally, Section 10.3.1 of the PDEP describes the means and timely notification of plant personnel following an emergency declaration and provisions for completing accountability within 60 minutes of an Alert declaration.
Section 10.3.2 of the PDEP describes the provisions for evacuating all visitors and unnecessary contractors upon an Alert declaration and radiological monitoring of personnel evacuated from the site.Section 10.5 of the PDEP has been revised to reflect that a range of protective actions for onsite personnel are addressed in Sections 10.2 through 10.4 of the PDEP. Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the revisions to Section 10.5.
BVY 15-009 / Attachment 1/ Page 18 of 24 VY-RAI-23 Section 11.1, "Emergency Notification" of the PDEP states, "The format and contents of the initial message between the plant and State authorities are specified in notification procedures and have been established with the review and agreement of responsible state authorities." Please provide documentation that this commitment has been reviewed with responsible state authorities to address the permanent shut down and defueled condition of facility.
In addition, has the frequency and format/content of follow-up reports been discussed with responsible state authorities based on the requested change in notification time requirements and the permanently shut down and defueled condition of the facility?Response As described in Section 7.1 of the PDEP, VY maintains the capability to communicate with the state emergency management agencies on a 24-hour basis and to convey specific accident information using the InForm Notification System (InForm).
This system is currently in use at VY. Within InForm, an Emergency Message is composed using a structured emergency data input that provides a format for the user. The data entered is used by InForm to compose the Emergency Message that is sent electronically to offsite authorities.
Preparation of the Emergency Message using the emergency data input will be evaluated following permanent cessation of operations to determine the necessary data inputs to the Emergency Message with consideration given to VY's permanently defueled condition.
Specific procedures supporting the PDEP, including the procedure associated with initial notification and follow-up messages to offsite authorities, have not yet been developed.
However, in accordance with 10 CFR 50.47(b)(5), VY will develop a procedure establishing the format and content of initial and follow-up messages and the frequency at which the messages are provided.
The procedure will address the permanently shutdown and defueled condition and the format and content of the initial and follow-up messages will be mutually agreed upon with responsible offsite authorities in accordance with the guidance contained in Planning Standard E, Evaluation Criterion 1 of NUREG-0654/FEMA-REP-1, "Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants" (November 1980).With respect to the frequency of follow-up messages, Section 9.2.2 of the current revision of the VY Emergency Plan, at an Alert, follow-up information is provided to offsite emergency organizations as needed. Additionally, Section 11.2 of the current revision of the VY Emergency Plan states that follow-up reports are provided on an as-needed basis until such time that the emergency condition has been terminated.
State agreement with the as-needed basis of follow-up messages is acceptable as evidenced by the existing Letters of Agreement.
VY has not proposed any changes to the frequency of follow-up reports in Sections 9.2.2 and 11.1 of the proposed PDEP.VY will develop the format and content of the initial and follow-up messages and provide the proposed messages to responsible offsite authorities for review prior to May 31, 2015. As indicated in the response to RAI-32, Letters of Agreement in support of the PDEP will be developed with consideration given to NRC-approved Regulatory Exemptions and the Permanently Defueled Emergency Action Levels (PD EALs) still under NRC review. VY will provide the Letters of Agreement to the NRC in a supplemental response to this RAI by June BVY 15-009 / Attachment 1/ Page 19 of 24 30, 2015. The Letters of Agreement will address the format and content of initial and follow-up messages and the frequency of follow-up messages.VY-RAI-24 Section 11.2, "Public Information" of the PDEP refers to the dissemination of information during an event at VY. Please explain how the following NUREG-0654/FEMA-REP-1 evaluation criteria are addressed under the Entergy Corporate Communication protocols:
- [G.4.a] Designated spokesperson, which should have access to all necessary information;
- [G.4.b] Arrangements for the timely exchange of information among designated company/agency spokespersons; and* [G.4.c] Coordinated arrangements for dealing with rumors.Additionally, please clarify how Entergy corporate communications protocols will continue to support the capability of Federal, State and local emergency response organizations to disseminate appropriate information regarding an emergency at VY.Response Because the VY Joint Information Center (JIC) is planned to be vacated following implementation of the PDEP and the current dedicated JIC company spokesperson position is planned for elimination, Entergy Nuclear Operations, Inc. (ENO) has not determined at this time exactly which, if any, revisions are needed to the current Entergy Corporate Communications protocols to ensure that the NUREG-0654/FEMA-REP-1 evaluation criteria will be addressed.
For the same reasons, it has yet to be determined if the protocols will require revision to ensure that they will support the capability of Federal, State and local emergency response organizations to disseminate appropriate information regarding an emergency at VY.A comprehensive response to this RAI, including any identified revisions to the PDEP, will be provided in a supplemental response by June 30, 2015.VY-RAI-25 Please clarify why the following offsite support organizations listed in Appendix D,"Letters of Agreement" of the PDEP are not provided the opportunity to participate in biennial exercises or periodic drills, as described in Section 12.1.1, "Radiation Emergency Exercises and Drills" of the PDEP:* Vernon Fire Department, and* Town of Vernon.Response The Vernon Fire Department and the Town of Vernon are currently, and will continue to be, provided the opportunity to participate in biennial exercises and periodic drills.Section 12.1.1 of the PDEP has been revised to include the Vernon Fire Department and the Town of Vernon. Attachment 2 of this letter provides the revised PDEP with the proposed BVY 15-009 / Attachment 1/ Page 20 of 24 changes shown in strikethrough and underline format resulting from the revisions to Section 12.1.1.VY-RAI-26 Please clarify why Section 12.1.4, "Fire Drills" of the PDEP only lists the Vernon Fire Department for demonstration of coordination with the plant's fire brigade, but does not address participation by the Brattleboro Fire Department, which is listed as an off-site support organization in Appendix D, "Letters of Agreement" of the PDEP.Response The Brattleboro Fire Department is currently, and will continue to be, provided the opportunity to participate in annual fire drills.Section 12.1.4 of the PDEP has been revised to include the Brattleboro Fire Department.
Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the revisions to Section 12.1.4.VY-RAI-27 Please clarify whether the Medical Drills, as discussed in Section 12.1.5 of the PDEP, will involve the actual participation of the Brattleboro Memorial Hospital and Rescue Inc.Ambulance Service, as off-site support organizations listed in Appendix D of the PDEP.Response Annual medical drills with a simulated contaminated injured individual currently, and will continue to, involve the actual participation of the Brattleboro Memorial Hospital and Rescue Inc. Ambulance Service as off-site support organizations.
Section 12.1.5 of the PDEP has been revised to incorporate this clarification.
Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the revisions to Section 12.1.5.VY-RAI-28 Under Section 12.2, "Training" of the PDEP, please describe site-specific emergency response training for those offsite emergency organizations who may be called upon to provide assistance in the event of an emergency, as outlined in NUREG-0654/FEMA-REP-1 Evaluation Criteria O.1.a.Response VY offers training annually to offsite response organizations which may be requested to provide assistance in the event of an emergency at VY (e.g., law enforcement, fire-fighting, rescue, medical services, transport of injured, etc.). The training is structured to meet the needs of the specific organization being trained to align with the nature of the support to be provided by the organization.
Topics such as event notification, site access procedures, basic radiation BVY 15-009 / Attachment 1/ Page 21 of 24 protection and interface activities between the offsite organization and VY are included in the training.Section 12.2 of the PDEP has been revised to include a discussion of the training offered to offsite organizations.
Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the revisions to Section 12.2.VY-RAI-29 Please provide copies of Emergency Plan Training Procedure AP 3712 and the Emergency Plan Training Program Description, as referenced In Section 12.2 of the PDEP, which describes specific details of the training given on an annual basis.Response The current versions of Emergency Plan Training Procedure AP 3712 and the Emergency Plan Training Program Description support the current VY Emergency Plan and are not fully applicable to the PDEP. Revisions to AP 3712 and the Emergency Plan Training Program Description will be developed to support the PDEP and will be provided to the NRC in a supplemental response by June 30, 2015.VY-RAI-30 Under Section 12.5, "Responsibility for Planning Effort" of the PDEP, describe how training is provided to individuals responsible for the planning effort, per NUREG-0654/FEMA-REP-1 Evaluation Criteria P.1.Response The Emergency Planning Manager is responsible for maintaining an adequate knowledge of regulations, planning techniques and the latest applications of emergency equipment and supplies.
Training for this position includes, but is not limited to: 1. Training courses specific or related to emergency preparedness;
- 2. Observation of, or participation in, drills and/or exercises at other decommissioned nuclear power plants;3. Participation in industry review and evaluation programs;4. Participation in regional or national emergency preparedness seminars, conferences, committees, workshops or forums.Section 12.5 of the PDEP has been revised to include a discussion of the training provided to individuals responsible for the planning effort. Attachment 2 of this letter provides the revised PDEP with the proposed changes shown in strikethrough and underline format resulting from the revisions to Section 12.5.
BVY 15-009 / Attachment 1/ Page 22 of 24 VY-RAI-31 Appendix B, "Emergency Equipment Inventory" lists specific radiological monitoring instruments/equipment, but merely indicates that it be provided by other non-affected Entergy nuclear sites, as needed. Please list what procedures are in place to coordinate obtaining/transporting or remotely utilizing this equipment, and describe an estimated time frame when equipment would become available for use in support of an emergency at the VY facility.Response VY does not maintain specific Emergency Plan Implementing Procedures for obtaining or transporting equipment from other non-affected Entergy nuclear sites. However, VY does maintain contact information with other Entergy facilities.
In the event that equipment is required, it can be obtained through established lines of communications within the Entergy fleet. In the event that equipment is obtained from other non-affected Entergy nuclear sites, the supplying facility will provide VY with the applicable operating procedures for the specific equipment being provided.
Based on the proximity of other Entergy nuclear sites in the region (Pilgrim, Indian Point, Fitzpatrick), it is estimated that any equipment that is requested could be provided within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> of the request being made.VY-RAI-32 Appendix D of the PDEP discusses various active and in-force letters of agreement with various offsite support organizations.
Please provide copies for staff review of letters of agreement applicable to this proposed PDEP, which will be in-force upon VY's permanent cessation of operations.
Response VY's existing Letters of Agreement with the offsite support organizations support the current VY Emergency Plan and are not fully applicable to the PDEP, which will be implemented approximately 15.4 months after permanent cessation of operations.
Development of the Letters of Agreement in support of the PDEP will be developed with consideration given to NRC-approved Regulatory Exemptions and the Permanently Defueled Emergency Action Levels (PD EALs) still under NRC review.VY will develop the Letters of Agreement and provide them to the NRC in a supplemental response by June 30, 2015.The following RAIs are for Attachment 3, "Permanently Defueled Emergency Action Level Technical Bases," of Entergy's June 12, 2014 submittal:
VY-RAI-33 Please annotate in Section 1, "Purpose" whether this document will be maintained in accordance with 10 CFR 50.54(q).Response The document will be maintained in accordance with 10 CFR 50.54(q).
The first paragraph of BVY 15-009 / Attachment 1 / Page 23 of 24 Section 1.0 of the Permanently Defueled Emergency Action Level Technical Bases concludes with the following statement: "All recommendations for changes to this document or associated implementing procedures are reviewed in accordance with 10 CFR 50.54(q)." VY-RAI-34[Page 32 of 51] EAL PD, "[Permanently Defueled" AU-2.2, basis discusses that if the area radiation monitors cannot detect or display values at or above 25 mR/hr over normal, then survey instruments can be used.* Verify whether the ranges of ARM-14 "Rx Bldg West RefueG" and ARM-15 "Spent Fuel Pool" are capable of detecting and displaying radiation levels at or above 25 mR/hr over normal.* Which area radiation monitors are known to not be capable of detecting or displaying values at or above 25 mR/hr over normal?* What would be the timeliness of performing local radiation surveys?Response The area radiation monitors (ARMs) that would indicate that an EAL threshold has been exceeded are ARM-14 (Rx Bldg West Refuel) and ARM-15 (Spent Fuel Pool). Both ARM-14 and ARM-1 5 indicate in the Control Room and are capable of detecting and displaying radiation levels at or above 25 mR/hr over normal background levels.Because the ARMs that would indicate whether an EAL threshold has been exceeded are capable of detecting and displaying radiation levels at or above 25 mR/hr over normal background levels, the statements included in the Vermont Yankee Basis for EALs PD-AU2.2 and PD-AU2.1 related to plant area radiation monitors that are unable to detect or display a reading that is 25 mR/hr over normal levels have been removed consistent with this response.However, if performance of local radiation surveys is required, this action would be performed in a timely manner, primarily because VY maintains a Radiation Protection (RP) Technician on-shift as indicated in Section 8.1.3 and Table 8.1 of the PDEP. Furthermore, additional station personnel, including additional RP Technicians, would be onsite to support fuel movement.Attachment 2 of this response provides the revised Permanently Defueled Emergency Action Level Technical Bases with the proposed changes shown in strikethrough and underline format resulting from the revisions to PD-AU2.1 and PD-AU2.2.VY-RAI-35[Page 51 of 51] EAL E, "Independent Spent Fuel Storage Installation" HU-1.1 basis provides the actual EAL values. Please explain why these values are not provided in the EAL itself to allow for timely event classification.
Response When making an emergency classification, the VY Emergency Director is trained to consider all information having a bearing on the proper assessment of an Initiating Condition prior to making the declaration.
This information includes the EAL and the associated basis information.
In the case of the subject EAL, this review would also include the ISFSI Technical Specifications.
BVY 15-009 / Attachment 1/ Page 24 of 24 Providing the ISFSI Technical Specification allowable levels in the Basis, rather than the EAL would not impact the timeliness of an event classification.
However, to facilitate timely event classification, the threshold values will be placed in the EAL.Attachment 3 of this response provides the revised Permanently Defueled Emergency Action Level Technical Bases with the proposed changes shown in strikethrough and underline format resulting from the revision to E- HU1.1.REFERENCES

SUMMARY
DATE TBD REVISION DESCRIPTION 0 The analyses of the potential radiological impact of accidents while the plant is in a permanently defueled condition indicate that no design basis accident or reasonably conceivable beyond design basis accident will be expected to result in radioactive releases that exceed Environmental Protection Agency (EPA) Protective Action Guides (PAGs) beyond the site boundary.
The slow progression rate of postulated event scenarios indicate sufficient time is available to initiate appropriate mitigating actions to protect the health and safety of the public. Therefore, the Permanently Defueled Emergency Plan adequately addresses the risk associated with VY's permanently defueled condition and continues to provide adequate protection for plant personnel and the public. Exemptions from the applicable portions of 10 CFR 50.47(b), Appendix E to 10 CFR Part 50 and 10 CFR 50.47(c)(2) were previously approved by the Nuclear Regulatory Commission (NRC).Permanently Defueled Emergency Plan Revision 0 Revision Summary Page-i-ef-4Paqe i of vii I Entergy Vermont Yankee TABLE OF CONTENTS

1.0 INTRODUCTION
The Permanently Defueled Emergency Plan (PDEP) describes the station's plan for responding to emergencies that may arise at the Vermont Yankee Nuclear Power Station (VY) while in a permanently shutdown and defueled configuration.
VY has provided certification to the Nuclear Regulatory Commission (NRC) required by 10 CFR 50.82(a)(1)(i) and (ii) that the station has permanently ceased operations and that all fuel has been permanently removed from the reactor vessel. In this configuration, all irradiated fuel is stored in the Independent Spent Fuel Storage Installation (ISFSI) and in the Spent Fuel Pool (SFP). In this condition, no reactor operations can take place and the station is prohibited from emplacement or retention of fuel in the reactor vessel. An analysis of the possible design basis events and consequences is presented in the evaluation of the Updated Final Safety Analysis Report (UFSAR) accident assessment.
This PDEP adequately addresses the risks associated with VY's current conditions.
The analysis of the potential radiological impact of a-n-desiqn basis accidents in a permanently defueled condition indicates that any releases beyond the Site boundary are below the Environmental Protection Agency (EPA) Protective Action Guide (PAG) exposure levels, as detailed in the EPA's "Protective Action Guide and Planning Guidance for Radiological Incidents," Draft for Interim Use and Public Comment dated March 2013 (PAG Manual). Exposure levels, which warrant pre-planned response measures, are limited to onsite areas. For this reason, radiological emergency planning is focused onsite.1.1. Purpose The purpose of the PDEP is to assure an adequate level of preparedness by which to cope with a spectrum of emergencies that could be postulated to occur, including the means to minimize radiation exposure to plant personnel.
This plan integrates the necessary elements to provide effective emergency response considering cooperation and coordination of organizations expected to respond to potential emergencies.
1.2. Scope
The PDEP has been developed to respond to potential radiological emergencies at VY considering the permanently shutdown and defueled status. Because there are no postulated design basis accidents that would result in dose consequences that are large enough to require off site emergency planning, the overall scope of this plan delineates the actions necessary to safeguard onsite personnel and minimize damage to property.
If determined appropriate by government officials, protective actions may be implemented to protect the public using an all -hazards approach to emergency planning.The concepts presented in this plan address the applicable regulations stipulated in 10 CFR 50.47, "Emergency Plans" and 10 CFR Part 50, Appendix E, "Emergency Planning and Preparedness for Production and Utilization Facilities." Permanently Defueled Emergency Plan Revision 0 Page 1 of 5360 Entergy Vermont Yankee Exemptions to selected portions of 10 CFR 50.47(b), 10 CFR 50.47(c)(2) and 10 CFR Part 50, Appendix E were previously approved by the NRC.Permanently Defueled Emergency Plan Revision 0 Page 2 of 5,60 Entergy Vermont Yankee

SUMMARY
OF EMERGENCY PLAN 3.1. Overview of Permanently Defueled Emergency Plan In the event of an emergency at the plant, actions are required to identify and assess the nature of the emergency and to bring it under control in a manner that protects the health and safety of plant personnel.
This plan describes the organization and responsibilities for implementing emergency measures.
It describes interfaces with Federal, States of Vermont and New Hampshire, the Commonwealth of Massachusetts and local organizations which may be notified in the event of an emergency, and may provide assistance.
Emergency services are provided by local public and private entities.
Fire support services are provided by the Vernon and Brattleboro Fire Departments and Tri-State and Southwestern Fire Mutual Aid Networks.Law enforcement support services are provided by local, county, state, and federal law enforcement authorities, as appropriate.
Ambulance service is provided by Rescue, Inc.Medical services are provided by Brattleboro Memorial Hospital.I Because there are no postulated design basis accidents that would result in off-site dose consequences that are large enough to require off-site emergency planning, emergencies I are divided into two classifications:
- 1) Notification of Unusual Event (Unusual Event); and 2)Alert. This classification scheme has been discussed and agreed upon with responsible offsite organizations and is compatible with their respective emergency plans. According to the EPA PAG Manual, "Emergency Planning Zones (EPZs) are not necessary at those facilities where it is not possible for PAGs to be exceeded off-site." If determined appropriate by government officials, protective actions may be implemented to Protect the public using an all -hazards approach to emergency planning.VY is responsible for planning and implementing emergency measures within the Site.This plan is provided to meet that responsibility.
To carry out specific emergency measures discussed in this Plan, detailed emergency plan implementing procedures are established and maintained.
In addition to the description of activities and steps that can be implemented during an emergency, this Plan also provides a general description of the steps taken to recover from an emergency situation.
It also describes the training, drills, planning, and coordination appropriate to maintain an adequate level of emergency preparedness.
3.2. Obiectives
The basic objectives of this plan are: 1) To establish a system for identification and classification of the emergency condition and initiation of response actions;Permanently Defueled Emergency Plan Revision 0 Page 5 of -5360 Entergy Vermont Yankee
- 2) To establish an organization for the direction of activity within the plant to limit the consequences of the incident;3) To establish an organization for control of surveillance activities to assess the extent and significance of any uncontrolled release of radioactive material;4) To identify facilities, equipment and supplies available for emergency use;5) To establish an engineering support organization to aid the plant personnel in limiting the consequences of and recovery from an event;6) To establish the basic elements of an emergency recovery program;7) To specify a system for coordination with federal, state/commonwealth, and local authorities and agencies for offsite support organizations;
- 8) To develop a communications network between the plant and offsite authorities to provide notification of emergency situations;
- 9) To develop a training and Emergency Plan exercise program to assure constant effectiveness of the plan.3.3. Actions in an Emergencv This Plan is activated by the Shift Manager upon identification of an emergency situation based upon Emergency Action Level (EAL) criteria.
The emergency measures described in the subsequent sections and emergency plan implementing procedures are implemented in accordance with the classification and nature of the emergency at the direction of the Shift Manager. Regulatory authorities and offsite support organizations are notified in accordance with this Plan. The Shift Manager has authority and responsibility for control and mitigation of the emergency, including emergency response resources, coordination of radiological assessment activities, and recovery implementation.
If an emergency condition develops, the Shift Manager assumes the role of Emergency Director, including responsibilities for initiating emergency actions to limit the consequences of the incident and to bring the plant into a stable condition.
The individual must: 1) Recognize the emergency condition by observation of EALs;2) Classify the accident in accordance with the emergency classification system;3) Initiate emergency procedure(s) applicable to the event;4) Activate the plant emergency alarm system;Permanently Defueled Emergency Plan Revision 0 Page 6 of -5,60 Entergy Vermont Yankee
- 5) Notify state-authorities in Vermont, New Hampshire and Massachusetts using the InForm Notification System;6) Notify the NRC using the Emergency Notification System (ENS);7) Use the notification plan to notify appropriate personnel as set forth in Figure 9.1;and 8) Direct and coordinate all emergency response efforts until overall responsibility is assumed by the Emergency Director.3.4. Emergency Response Facilities The emergency response facilities, which are utilized by the Emergency Response Organization (ERO), are described in Section 6.0. Key site personnel are dispatched to perform accident assessments, implement corrective actions, and analyze accident data.3.5. Mobilization The mobilization scheme is based on the emergency notification system shown in Figure 9.1. The notification system utilizes the plant public address system (Gai-Tronics), dedicated telephone lines, and the ERO notification system to notify and mobilize plant personnel.
The mobilization scheme ensures that specific technical disciplines can be augmented within appropriate time frames. On-site staff are informed of an emergency condition through the use of the plant public address system, office telephone and/or wireless devices capable of receiving telephone calls and text messages.
In the event that personnel required to staff emergency positions are not on-site at the time an emergency is declared, they may be contacted by commercial telephone including land lines and/or wireless devices capable of receiving telephone calls and text messages.
Mobilization of the ERO will be conducted under the direction of the Emergency Director, according to personnel assignments and telephone numbers maintained in various telephone directories.
Section 8.2, Figure 8.1 and Table 8.1 outline the minimum staffing requirements for the ERO at VY.3.6. State and Local Government Notification and Response VY's Emergency Plan interfaces with the state-emergency response plans of Vermont, New Hampshire and the Commonwealth of Massachusetts.
Vernon, Vermont, in coordination with the emergency management agencies of Vermont, maintains the capability to communicate on a 24-hour per day basis.VY conveys specific accident information to the States of Vermont and New Hampshire and the Commonwealth of Massachusetts using the InForm Notification System.A cooperative arrangement exists among the Vermont and New Hampshire and the Commonwealth of Massachusetts State-authorities and VY concerning radiological Permanently Defueled Emergency Plan Revision 0 Page 7 of 5360 Entergy Vermont Yankee emergency preparedness.
VY's emergency classification system and notification I messages are reviewed with these States-/Commonwealth Of-VeFmOn-on an annual basis.3.7. Federal Government Notification and Response Notification to the NRC is made using the ENS as soon as possible after State/Commonwealth notifications and within 60 minutes of event classification or change in classification.
Once notified of an emergency, the NRC evaluates the situation and determines the appropriate NRC response.
Depending on the severity of the accident and the emergency classification declared, the NRC activates their incident response operations in accordance with the NRC Incident Response Plan. If the emergency warrants, the NRC notifies the Federal Emergency Management Agency (FEMA) and other appropriate federal agencies to activate the federal emergency response organization in accordance with the National Response Framework (NRF). The NRF makes available the resources and capabilities of federal agencies to support plant, state and local governments, as necessary to respond to the specific nature of the emergency.
Principal participants are the NRC, FEMA, Department of Energy (DOE), and Environmental Protection Agency (EPA).3.8. Technical Support In the event of an emergency that requires personnel and other support resources beyond those available within the VY organization, augmentation is available from other Entergy facilities and can be requested from various contractors.
Additional technical and manpower support are provided to VY through support plans listed in Appendix E.3.9. Mitigation of Consequences of Beyond Design Basis Events Strategies to mitigate a loss of SFP inventory and prevent a zirconium fire are contained within Appendix G, "Loss of Large Areas of the Plant Due to Fire or Explosion," of PP 7019,"Severe Accident Management Program." Appendix G of PP 7019 describes the equipment, resources (such as water supplies), procedures and strategies in place for movement of any necessary portable equipment that will be relied upon for prevention of a zirconium fire in the SFP. These mitigative strategies were developed as a result of NRC Order on Mitigative Strategies (EA-1-2-04902-026) and implement the requirements of License Condition 3.N, "Mitigation Strategy License Condition." Permanently Defueled Emergency Plan Revision 0 Page 8 of -51,60 Entergy Vermont Yankee 4.0 SITE DESCRIPTION
4.1. Facility
Description VY is located on the west bank of the Connecticut River immediately upstream of the Vernon Hydrostation, in the town of Vernon, Vermont. VY consists of a permanently shutdown boiling water reactor having a thermal rated power of 1912 MWt. An ISFSI is located on the plant site. The station, shown in Figure 4.1, is located on about 125 acres in Windham County, and is owned by Entergy, with the exception of a narrow strip of land between the Connecticut River and the VY property for which it has perpetual rights and easements from the owner, New England Power Company.The 10 CFR Part 50 license for VY no longer authorizes operation of the reactor;-
or emplacement or retention of fuel into the reactor vessel, as specified in 10 CFR 50.82(a)(2).
4.2. Area Characteristics and Land Use The site is bounded by the Connecticut River (Vernon Pond) on the east, by farm and pasture land mixed with wooded areas on the north and south, and by the town of Vernon on the west. Most of the land around the site is undeveloped.
The developed land is used for agriculture, dairying, and for residential areas within small villages.
The nearest residence is 1,300 feet from the Reactor Building and is one of several west of the site.The Vernon Elementary School (approximate enrollment of 250 pupils) is about 1,500 feet from the Reactor Building.
The nearest hospital, Brattleboro Memorial, is approximately five (5) miles north-northwest from the site.Permanently Defueled Emergency Plan Revision 0 Page 9 of &360 Entergy Vermont Yankee raidius Vermont YVankee Nuclear Power Station Vernon facinnaimy School CJUV'anor

5.0 EMERGENCY
CLASSIFICATION SYSTEM The emergency classification system covers an entire spectrum of possible radiological and non-radiological emergencies at the VY. The emergency classification system categorizes accidents and emergency situations, according to severity, into two emergency classification levels: Unusual Event and Alert.The incidents leading to each of the emergency classifications are further identified by certain measurable and observable indicators of plant conditions (EALs). EALs addressed in Appendix A aid the operator in recognizing the potential of an incident immediately and assure that the first step in the emergency response is carried out. The classification of the event may change as the conditions change. VY maintains the capability to assess, classify and declare an emergency condition in accordance with site procedures.
EALs and EAL bases were derived from NEI 99-01, "Development of Emergency Action Levels for Non-Passive Reactors" Rev. 6, for classifying emergencies.
Specifically, Appendix C of NEI 99-01, Rev. 6 contains a set of Initiating Conditions/
EALs for permanently defueled nuclear power plants that had previously operated under a 10 CFR Part 50 license and have permanently ceased operations.
The classification system referenced in NEI 99-01, Rev. 6 has been endorsed by the NRC and provides a standard method for classifying emergencies.
5.1. Unusual
Event EVENTS ARE IN PROGRESS OR HAVE OCCURRED WHICH INDICATE A POTENTIAL DEGRADATION OF THE LEVEL OF SAFETY OF THE PLANT OR INDICATE A SECURITY THREAT TO FACILITY PROTECTION HAS BEEN INITIATED.
NO RELEASES OF RADIOACTIVE MATERIAL REQUIRING OFFSITE RESPONSE OR MONITORING ARE EXPECTED UNLESS FURTHER DEGRADATION OF SAFETY SYSTEMS OCCURS.Unusual Event conditions do not cause serious damage to the plant. The purpose of the Unusual Event declaration is to: 1) provide for an increased awareness of abnormal conditions;
- 2) ensure that the first step in any response later found to be necessary has I been carried out; 3) bring the ERO to a state of readiness;
- 4) te-provide for systematic handling of information and decision-making, and 5) augment on-shift personnel, if deemed necessary by the Emergency Director.See Appendix A for a complete list of EALs corresponding to an Unusual Event.5.2. Alert EVENTS ARE IN PROGRESS OR HAVE OCCURRED WHICH INVOLVE AN ACTUAL OR POTENTIAL SUBSTANTIAL DEGRADATION OF THE LEVEL OF SAFETY OF THE PLANT OR A SECURITY EVENT THAT INVOLVES PROBABLE LIFE THREATENING RISK TO SITE PERSONNEL Permanently Defueled Emergency Plan Revision 0 Page 11 of .5360 Entergy Vermont Yankee OR DAMAGE TO SITE EQUIPMENT BECAUSE OF HOSTILE ACTION.ANY RELEASES ARE EXPECTED TO BE LIMITED TO SMALL FRACTIONS OF THE EPA PAG EXPOSURE LEVELS.The purpose of the Alert declaration is to: 1) activate the Emergency Response Organization to perform event mitigation and radiation monitoring, if required, 2) provide the State of Vermontoffsite authorities and the NRC with current information on plant status, and 3) ensure that all necessary resources are being applied to accident mitigation.
Plant responses associated with this event classification assure that sufficient emergency response personnel are mobilized and respond to event conditions.
Actual releases of radioactivity which exceed Technical Specification limits may be involved, thus radiation monitoring and dose projection may be required.See Appendix A for a complete list of EALs corresponding to an Alert.5.3. Emergency Classification System Review by State Authorities The emergency classification system specified above and the EALs presented in Appendix A, are reviewed with the state-authorities of Vermont, New Hampshire and Massachusetts annually.Permanently Defueled Emergency Plan Revision 0 Page 12 of 5360 Entergy Vermont Yankee
6.0 EMERGENCY
RESPONSE FACILITIES AND EQUIPMENT Following the declaration of an emergency, the activities of the emergency response organization are coordinated in the Control Room. Descriptions of VY facilities and assessment capabilities are presented below.6.1. Control Room The Control Room is where plant systems and equipment parameters are monitored.
Control Room personnel assess plant conditions, evaluate the magnitude and potential consequences of abnormal conditions, initiate preventative, mitigating and corrective actions and perform notifications.
The Control Room is the onsite center for emergency command and control.The Control Room crew coordinates all phases of emergency response and corrective action required to restore the plant to a safe condition.
Classification and subsequent declaration of the appropriate emergency condition by the Shift Manager results in activation of the ERO. The Control Room staff's attention focuses on mitigating the emergency as the ERO reports and is delegated emergency functions.
When activated, the ERO reports to the Emergency Director to assist the on-shift staff in the assessment, mitigation and response to an emergency and to support the dispatch of emergency teams. The composition of the ERO is addressed in Section 8.2.ERO activation may be modified or suspended if the safety of personnel may be jeopardized by a security event or other event hazardous to personnel.
The Control Room contains communications equipment, emergency radiation monitoring equipment, emergency respiratory devices, and an emergency kit containing protective clothing and other supplies.
The ERO has access to up-to-date technical documentation, including drawings, system information and procedures to enable mitigation planning and support of Control Room staff.A general assembly area for emergency mitigation and radiation protection personnel is maintained.
6.2. Assessment
Capability The activation of the Emergency Plan and the continued assessment of accident conditions require monitoring and assessment capabilities.
VY maintains and operates on-site monitoring systems needed to provide data that is essential for initiating emer-gency measures and performinq accident assessment, including dose assessment and assessing the magnitude of a release. This includes monitorinq systems for plant processes, radiological conditions, meteorological conditions, and fire hazards. The essential monitoring systems needed are incorporated in the EALs specified in Appendix A. This section briefly describes monitoring systems as well as other assessment capabilities.
Permanently Defueled Emergency Plan Revision 0 Page 13 of -5360 Entergy Vermont Yankee
6.2.1. Process
Monitors Annunciator and computer alarms are provided for a variety of parameters including the SFP cooling system to indicate SFP level, temperature and pump status.The manner in which process monitors are used for accident recognition and classification is given in the detailed EAL listings in Appendix A.6.2.2. Radiological Monitors A number of radiation monitors and monitoring systems are provided on process and effluent liquid and gaseous lines that serve directly or indirectly as discharge route for radioactive materials.
These monitors, which include Control Room readout and alarm functions, exist in order that appropriate action can be initiated to limit fuel damage and/or contain radioactive material.
The equipment
- 1) provides radiological surveillance capabilities;
- 2) warns personnel of a radiological release; 3) provides warning of certain plant malfunctions which might lead to a radiological release; and 4) prevents, or minimizes, the effects of an accidental release of radioactivity to the environment.
Plant instrumentation provide personnel in the Control Room with the following parameters necessary to perform dose assessment and determine the magnitude of a potential release:* Gaseous and liquid effluent monitor readings* Radiation levels* SFP area radiation levels Specific details on these monitoring systems such as location, type, etc., are contained in the UFSAR.In addition to installed monitoring systems, VY has augmented onsite radiological assessment capability, including portable radiation and contamination monitoring instruments and sampling equipment.
6.2.3. Meteorological
Capability The meteorological equipment at the site consists of wind-speed and direction transmitters, signal translators, and recorders.
In addition, the temperature measurement consists of recorders and resistance temperature detectors (RTDs). RTDs are used to monitor ambient temperature and calculate differential temperature.
Meteorological data is displayed in the Control Room. These meteorological data is used to determine the proiected radiological conditions in the event of an accidental release of radioactivity to the environment.
Permanently Defueled Emergency Plan Revision 0 Page 14 of -5360 Entergy Vermont Yankee In addition, VY has the capability to access additional meteorological information through offsite support services.

7.0 COMMUNICATIONS
Various modes of communication are available to plant staff to transmit information within VY and to various locations offsite during normal and emergency conditions.
A summary of the communication systems is defined in the communication matrix provided in Table 7.1 and outlined below.7.1. InForm Notification System The InForm Notification System is located in the Control Room. InForm consists of source and destination computers that take advantage of the internet to send Emergency Notification Forms to the States of Vermont, New Hampshire and the Commonwealth of Massachusetts.
This system is staffed on a 24-hour basis on both ends -the Control Room and the State Police dispatching points. InForm performs self-checks at frequent intervals and has the ability to notify personnel of any problems identified during the self-check.
InForm is tested monthly between the Control Room and the State/Commonwealth Police dispatching points.Backup to the InForm Notification System is the Nuclear Alert System (NAS).7.2. Nuclear Alert System The NAS can be used to notify the State/Commonwealth Police of Vermont, New Hampshire and Massachusetts of any emergency.
This system is a secure (dedicated) communications arrangement.
This system is staffed on a 24-hour basis in the Control Room and by the I State/Commonwealth Of VermontPol4ca Dispatchinq Points. The NAS is tested monthly between the plant and the State/Commonwealth agencies.The NAS links the Control Room and the Vermont Emergency Operations Center.Backup to the NAS phone system is the commercial phone system.7.3. ERO Notification System The ERO notification system is the primary means to activate the ERO upon declaration of an emergency, as directed by the Emergency Director.
In the event that personnel required to staff emergency positions are not on-site at the time an emerqency is declared, they may be contacted by commercial telephone including land lines and/or wireless devices capable of receiving telephone calls and text messages.
Telephone numbers are maintained in various telephone directories.
This system is tested as described in Section 12.1.2.Permanently Defueled Emergency Plan Revision 0 Page 16 of 5360 Entergy Vermont Yankee

9.0 EMERGENCY
RESPONSE 9.1. Emercency Condition Recognition and Classification VY maintains the capability to assess, classify, and declare an emergency condition.
in accordance with plant procedures, within 30 minutes after the availability of indications to plant operators that an emergency action level threshold has been reached. foll,;inq ide-R4iciatiGn of thcII aprite emergcncy Glasszific~ati(on lcvc!.Section 5.0 presents the emergency classification system used for categorizing the wide spectrum of possible emergency conditions into one of two emergency classes. The process of condition recognition, immediate response to correct the condition, event classification, and initiation of the appropriate emergency implementing procedures are critical responsibilities of the Shift Manager and the on-shift crew.Site procedures contain the listing of conditions that represents each of the two emergency categories and the detailed EALs that allow the Shift Manager to determine the emergency classification.
Once the emergency is classified, the applicable emergency implementing procedure is initiated, the ERO is activated and the notification of offsite authorities is initiated.
The activation of the ERO brings to the assistance of the on-shift personnel the various support elements described in this plan. Specific support elements are implemented as detailed in the emergency implementing procedures.
See Appendix E for a listing of these procedures.
9.2. Activation
of the Emergency Response Organization Classification of an accident condition requires that the plant staff recognize that pre-established EALs associated with an emergency condition, as defined in Appendix A, have been reached or exceeded.
Depending upon the specific action levels attained, the Shift Manager declares one of the following:
Unusual Event or Alert. The Shift Manager activates the ERO if plant conditions reach predetermined EALs.9.2.1. Unusual Event Response Appendix A defines the conditions that require the declaration of an Unusual Event. An Unusual Event does not activate the ERO, but may require augmentation of on-shift resources to address the event. Offsite emergency organizations are notified for informational purposes, and aid from offsite fire, medical, and security organizations may be required depending on the nature of the event.The response required as a result of this declaration of a Unusual Event varies according to the specified event, but a general summary of actions taken is described below: 1. The emergency condition is recognized and classified by the Shift Manager who instructs Control Room personnel to announce the emergency classification over the plant page system;Permanently Defueled Emergency Plan Revision 0 Page 28 of 5,360 Entergy Vermont Yankee
- 2. The on-duty and selected plant personnel respond as directed by the Shift Manager and assume assigned functions;
- 3. Control Room personnel notify the Vermont, New Hampshire and Massachusetts State-authorities;
- 4. The NRC is notified;5. Other support is requested as necessary;
- 6. The Emergency Call-in Method is implemented as shown in the notification plan (Figure 9.1);7. Additional personnel report to the plant as requested by the Shift Manager;8. The Shift Manager/Emergency Director directs the activities of emergency response personnel;
- 9. If necessary, appropriate emergency medical, fire department, or law enforcement agencies are notified and requested to respond;10. The public information representative is notified and handles public information associated with the event; and 11. The Shift Manager/Emergency Director terminates the Unusual Event status and closes out the event with a verbal summary to offsite authorities or escalates to higher level emergency classification.
The Unusual Event status will be maintained until an escalation in emergency class occurs or the event is terminated.
Offsite authorities will be informed of the change in the emergency status and the necessary documentation will be completed as specified in site procedures.
9.2.2. Alert
Response An Alert requires actions to assure that sufficient emergency response personnel are mobilized to respond to the accident conditions at the site. Notification is made to State/Commonwealth officials and follow-up information is provided as needed to offsite emergency organizations.
In an Alert, the steps listed in the Unusual Event Response section (except for the termination process) and the following are performed:
- 1. ERO report to the Emergency Director;2. The Emergency Director/Shift Manager directs the evacuation of all visitors and unnecessary contractors from the plant;Permanently Defueled Emergency Plan Revision 0 Page 29 of .5360 Entergy Vermont Yankee
- 3. If sufficient personnel are not available onsite, off-duty personnel are called in as specified in the emergency implementing procedures;
- 4. The Emergency Director assumes total responsibility for overall emergency response actions and recovery;5. The Emergency Director reaches agreement with offsite authorities concerning de-escalation or termination of the event, and closes out the event by verbal summary to off site authorities.
If an event is a reportable occurrence, a written summary is issued to these authorities in an appropriate time frame through distribution by the Emergency Director.The Alert status shall be maintained until termination of the event or de-escalation in emergency class occurs. The plant may enter recovery operation without de-escalating from a declared Alert. Off-site authorities will be informed of the change in the emergency status and the necessary documentation shall be completed as specified in site procedures.
9.3. Emergency
Termination Criteria An extensive review of plant parameters including SFP parameters and process and radiation monitoring systems, in conjunction with the pre-established EALs is required to terminate an emergency.
When plant conditions allow de-escalation in the emergency class, the Emergency Director directs the emergency response organization to perform certain response actions prior to implementing any change. These actions include: 1. Notification of all plant emergency management personnel of the pending change;2. Notification of offsite authorities of the pending change;3. Notification of corporate support services of the pending change;4. Coordination of media releases concerning the transition; and 5. Announcement of the transition over the plant page system.Termination of an emergency status is the responsibility of the Emergency Director.
The decision will be based on the following considerations:
- 1. Conditions no longer meet an EAL and it appears unlikely that conditions will deteriorate; Permanently Defueled Emergency Plan Revision 0 Page 30 of 5360 Entergy Vermont Yankee
- 2. Plant releases of radioactive materials to the environment are under control (within Technical Specifications);
- 3. In-Plant radiation levels are stable or decreasing, and are acceptable given plant conditions;
- 4. Operability and integrity of power supplies, electrical equipment and plant instrumentation including radiation monitoring equipment is acceptable;
- 5. All required notifications have been made;6. Radiological and plant conditions permit resumption of normal occupational exposure limits to continue mitigation/repair activities.

Radiological Assessment 10.1.1. Initial Radiological Dose Projection VY has developed a method to quickly determine the projected radiological conditions at the Site boundary.
During the initial stages of an emergency, the Shift Manager or designated individual is responsible to perform the initial evaluation of radiological conditions.
The initial evaluation is accomplished in accordance with site procedures.
10.2. Radiological Exposure Control During a plant emergency, abnormally high levels of radiation and/or radioactivity may be encountered by plant personnel.
All reasonable measures shall be taken to control the radiation exposure to emergency response personnel providing rescue, first aid, decontamination, emergency transportation, medical treatment services, or corrective or assessment actions within applicable limits specified in 10 CFR Part 20.Table 10.1 specifies the guidelines on emergency dose limits for personnel providing emergency response duties consistent with Table 2-2, "Response Worker Guidelines," provided in the EPA PAG Manual. The Shift Manager/Emergency Director has the responsibility to authorize emergency dose commitments in excess of 10 CFR Part 20 limits. This authorization is coordinated with the assistance of the Radiation Protection Coordinator.
Exposure to individuals providing emergency functions will be consistent with the limits specified in Table 10.1 with every attempt made to keep exposures As Low As Reasonably Achievable (ALARA).The Radiation Protection Coordinator is responsible for developing emergency radiological protection programs for ERO and augmented personnel.
Emergency kits are provided with self-reading dosimeters.
Each member reporting to the site will be provided a Dosimeter of Legal Record (DLR). Dose records will be maintained based upon the results of the self-reading dosimeters.
This information is cross-referenced with the DLR data. The capability exists for the emergency processing of DLRs on a 24-hour per day basis.Emergency workers are instructed to read self-reading dosimeters frequently, and DLRs may be processed with increased periodicity.
10.3. Protective Measures 10.3.1. Site Personnel Accountability The goal of the personnel accountability process is to account for personnel at-within 60 minutes of an Alert declaration.
Accountability for an Unusual Event is at the discretion of the Emergency Director.
Plant procedures require Security personnel to maintain a list of personnel entering or leaving the site during a site evacuation.
In accordance with site procedures, following announcement of an emergency classification, plant personnel are Permanently Defueled Emergency Plan Revision 0 Page 33 of -5360 Entergy Vermont Yankee responsible for reporting to designated areas and aiding Security in the accountability process.The Emergency Director, Technical Coordinator and Radiation Protection Coordinator are responsible for accounting for their staff. An organizational sign-in method which enhances this reporting process is maintained.
All reports are provided to the Emergency Director, who initiates search and rescue actions for any missing personnel.
Plant security provides assistance for this accountability effort and aids in the control of personnel during extended emergency operations.
If personnel are not accounted for, the Control Room is notified and announcements are made using the plant page system. If personnel are still unaccounted for following Control Room announcements, Security will initiate sweeps to locate the missing individuals.
Accountability may be modified or suspended if the safety of personnel may be jeopardized by a Security event or other event hazardous to personnel.
10.3.2. Site Egress Control Methods All visitors and unnecessary contractors are evacuated from the plant upon an Alert declaration.
All personnel are monitored for radioactive contamination prior to leaving the site. Portable radiation survey meters are available to frisk personnel for suspected contamination.
If a Code Red Security event has been declared, evacuation and accountability may put personnel at risk. In these security situations, evacuation and accountability may be suspended until directed by Security.Plant evacuees are advised of evacuation procedures prior to being released.10.3.3. Contamination Control and Decontamination Capability During emergency conditions, VY maintains normal plant decontamination and contamination control measures as closely as possible.
However, these measures may be modified by the Emergency Director should conditions warrant.VY maintains contamination control measures to address area access control, drinking water and food supplies, and the return of areas and items to normal use.a. Contaminated areas are isolated as restricted areas with appropriate radiological protection and access control. Personnel leaving contaminated areas are monitored to ensure both themselves and their clothing are not contaminated.
Supplies, instruments, and equipment that are in contaminated areas or have been brought into contaminated areas will be monitored prior to removal. Items found to be contaminated, will be decontaminated using normal plant decontamination technigues and facilities or may be disposed of as radioactive waste.Permanently Defueled Emergency Plan Revision 0 Page 34 of -5360 Entergy Vermont Yankee
- b. Should the potential exist for contarnination of on-site food or drinking water supplies that renders these supplies non-consumable, VY will make arrangements for transport of non-contaminated off-site supplies.c. VY permits areas and items to be returned to normal use following conduct of appropriate surveys and verification that contamination levels have returned to acceptable levels.VY maintains an in-plant decontamination facility.
Waste generated through the use of this system is collected and processed by the plant liquid radwaste system. Survey instrumentation for personnel "frisking" and sensitive body burden monitoring equipment are available in various plant locations.
Decontamination is performed under the direction of the Radiation Protection Coordinator.
10.3.4. Use of Onsite Protective Equipment and Supplies The plant supplies of personnel radiation protection equipment and gear are utilized to support the emergency response effort. Equipment such as respiratory protection gear and protective clothing is assigned to emergency response organization members and plant response personnel in accordance with established plant radiation protection criteria.10.3.5. Fire Fighting Strategies have been developed for firefighting and fire protection in specific critical areas of the plant. The Fire Protection Program describes the fire protection organization and individual responsibilities.
10.4. Aid to Affected Personnel 10.4.1. Medical Treatment In-plant medical supplies are provided on-site. Initial on-site medical treatment is provided by on-site personnel.
Arrangements exist with Brattleboro Memorial Hospital as indicated in Section 8.2.3.1. The agreement includes a commitment by the hospital to accept and treat plant personnel with routine industrial injuries as well as injuries complicated by radioactive contamination or radiation exposure.
The hospital maintains the capability and facilities to provide decontamination.
The hospital participates in medical emergency drills.10.4.2. Medical Transportation Arrangements exist with Rescue, Inc., to provide 24-hour ambulance service for emergency transportation of plant personnel for offsite treatment.
The ambulance service is capable of radio communications with the hospital while en route with a patient.

Emergency Notification The Shift Manager is responsible for the notification of an emergency declaration to the I States of Vermont and New Hampshire and the Commonwealth of Massachusetts.
Notification is made within 60 minutes of emergency declaration or change in classification.
Due to the slow rate of the postulated event scenarios in the accident analysis and the absence of immediate actions necessary to protect the public health and safety, the notification time of 60 minutes is appropriate.
The format and contents of the initial message between the plant and State/Commonwealth authorities are specified in notification procedures and have been established with the review and agreement of responsible state authorities.
I The Department of Public Health of Vermont, New Hampshire and Massachusetts may request the following information from VY: 1. Date and time of the incident;2. Emergency classification;
- 3. Status of the facility;.4. Whether a release has occurred, is occurring, or is anticipated to occur;5. Actual or projected dose rates at the Site boundary;Follow-up reports are provided as additional information describing the emergency situation becomes available and on an as-needed basis until such time that the emergency condition has been terminated.
11.2. Public Information Any emergency generates a continuous and intensive demand for up-to-date information.
As part of its normal corporate structure, Entergy maintains a corporate public affairs office.Upon declaration of an Unusual Event or Alert, information is disseminated to the public and briefings will be held with pertinent media organizations in accordance with Entergy corporate communication protocols.
Additionally, Federal, State and local emergency response organizations maintain the capability to disseminate appropriate information regarding an emergency at VY.VY maintains a public inquiry phone for media and public use. During an emergency, a pre-recorded message will provide up-to-date status reports regarding the situation.

1.0 PURPOSE
This document provides the detailed set of Emergency Action Levels (EALs) applicable to the Vermont Yankee Nuclear Power Station (VY) and the associated Technical Bases using the EAL development methodology found in NEI 99-01, "Development of Emergency Action Levels for Non-Passive Reactors," Revision 6 (NEI 99-01, Rev. 6). As a Permanently Defueled Station, VY will use the Recognition Category "PD" (Permanently Defueled) providing a stand-alone set of ICs/EALS for a permanently defueled nuclear power plant to consider for use in developing a site-specific emergency classification scheme. (Permanently defueled station ICs and EALs are addressed in Appendix C of NEI 99-01, Rev. 6.) All recommendations for changes to this document or associated implementing procedures are reviewed in accordance with 10 CFR 50.54(q).This document should be used to facilitate review of the VY EALs, provide historical documentation for future reference and serve as a resource for training.
Decision-makers responsible for implementation of AP-3125, Emergency Plan Classification and Action Level Scheme, may use this document as a technical reference in support of EAL interpretation.
The expectation is that emergency classifications are to be made as soon as conditions are present and recognizable for the classification, but within 60 minutes or less in all cases of conditions present. Use of this document for assistance is not intended to delay the emergency classification.
2.0 DISCUSSION
2.1 Permanently
Defueled Station NEI 99-01 provides guidance for an emergency classification scheme applicable to a permanently defueled station. This is a station that generated spent fuel under a 10 CFR Part 50 license, has permanently ceased operations and will store the spent fuel onsite for an extended period of time. The emergency classification levels applicable to this type of station are consistent with the requirements of 10 CFR Part 50 and NUREG-0654/FEMA-REP-1,"Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants, Rev. 1" (NUREG-0654).
In order to relax the emergency plan requirements applicable to an operating station, the owner of a permanently defueled station must demonstrate that no credible event can result in a significant radiological release beyond the site boundary.
It is expected that this verification will confirm that the source term and motive force available in the permanently defueled condition are insufficient to warrant classifications of a Site Area Emergency or General Emergency.
Therefore, the generic Initiating Conditions (ICs) and Emergency Action Levels (EALs)applicable to a permanently defueled station may result in either a Notification of Unusual Event (Unusual Event) or Alert classification.
2.2 Independent
Spent Fuel Storage Installation Selected guidance in NEI 99-01, Rev. 6 is applicable to licensees electing to use their 10 CFR Part 50 emergency plan to fulfill the requirements of 10 CFR 72.32 for a stand-alone Independent Spent Fuel Storage Installation (ISFSI). The emergency classification levels applicable to an ISFSI are consistent with the requirements of 10 CFR Part 50. The initiating Permanently Defueled EAL Technical Bases Vermont Yankee Nuclear Power Station Rev. 0 Page 4 of 52 conditions germane to a 10 CFR 72.32 emergency plan (as described in NUREG-1567) are subsumed within the classification scheme for a 10 CFR 50.47 emergency plan.The analysis of potential onsite and offsite consequences of accidental releases associated with the operation of an ISFSI is contained in NUREG-1 140, "A Regulatory Analysis on Emergency Preparedness for Fuel Cycle and Other Radioactive Material Licensees" (NUREG-1 140).NUREG-1 140 concluded that the postulated worst-case accident involving an ISFSI has insignificant consequences to public health and safety. This evaluation shows that the maximum offsite dose to a member of the public due to an accidental release of radioactive materials would not exceed 1 rem Effective Dose Equivalent.
Regarding the above information, the expectations for an offsite response to an Alert classified under a 10 CFR 72.32 emergency plan are generally consistent with those for an Unusual Event in a 10 CFR 50.47 emergency plan (e.g., to provide assistance, if requested).
Also, the licensee's Emergency Response Organization (ERO) required for 10 CFR 72.32 emergency plan is different than that prescribed for a 10 CFR 50.47 emergency plan (e.g., no emergency technical support function).

3.1 Emergency
Classification Level One of a set of names or titles established by the US Nuclear Regulatory Commission (NRC) for grouping off-normal events or conditions according to (1) potential or actual effects or consequences, and (2) resulting onsite and offsite response actions. The emergency classification levels, in ascending order of severity, are:* Unusual Event* Alert 3.1.1 Unusual Event Events are in progress or have occurred which indicate a potential degradation of the level of safety of the plant or indicate a security threat to facility protection has been initiated.
No releases of radioactive material requiring offsite response or monitoring are expected unless further degradation of safety systems occurs.Purpose: The purpose of this classification is to assure that the first step in future response has been carried out, to bring the operations staff to a state of readiness, and to provide systematic handling of unusual event information and decision-making.3.1.2 Alert Events are in progress or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant or a security event that involves probable life threatening risk to site personnel or damage to site equipment because of HOSTILE ACTION. Any releases are expected to be limited to small fractions of the EPA PAG exposure levels.Purpose: The purpose of this classification is to assure that emergency personnel are readily available to respond if the situation becomes more serious or to perform confirmatory radiation monitoring if required, and provide offsite authorities current information on plant status and parameters.
3.2 Initiating
Condition An event or condition that aligns with the definition of one of the two emergency classification levels by virtue of the potential or actual effects or consequences.
Discussion:
An Initiating Condition (IC) describes an event or condition, the severity or consequences of which meets the definition of an emergency classification level. An IC can be expressed as a continuous, measurable parameter (e.g., radiation monitor readings) or an event (e.g., an earthquake).
Appendix 1 of NUREG-0654 does not contain example EALs for each ECL, but rather Initiating Conditions (i.e., plant conditions that indicate that a radiological emergency, or events that could lead to a radiological emergency, has occurred).
NUREG-0654 states that the Initiating Conditions form the basis for establishment by a licensee of the specific plant instrumentation readings (as applicable) which, if exceeded, would initiate the emergency classification.
Thus, it is the specific instrument readings that would be the EALs.Permanently Defueled EAL Technical Bases Vermont Yankee Nuclear Power Station Rev. 0 Page 6 of 52
3.3 Emergency
Action Level A pre-determined, site-specific, observable threshold for an IC that, when met or exceeded, places the plant in a given emergency classification level.Discussion:
EAL statements may utilize a variety of criteria including instrument readings and status indications; observable events; results of calculations and analyses; entry into particular procedures; and the occurrence of natural phenomena.
4.0 GUIDANCE
ON MAKING EMERGENCY CLASSIFICATIONS
4.1 General
Considerations When making an emergency classification, the Emergency Director must consider all information having a bearing on the proper assessment of an IC. This includes the EAL plus Notes and the informing Basis information.
All emergency classification assessments should be based upon valid indications, reports or conditions.
A valid indication, report, or condition, is one that has been verified through appropriate means such that there is no doubt regarding the indicator's operability, the condition's existence, or the report's accuracy.
For example, validation could be accomplished through an instrument channel check, response on related or redundant indicators, or direct observation by plant personnel.
The validation of indications should be completed in a manner that supports timely emergency declaration.
For ICs and EALs that have a stipulated time duration (e.g., 15 minutes, 60 minutes, etc.), the Emergency Director should not wait until the applicable time has elapsed, but should declare the event as soon as it is determined that the condition has exceeded, or will likely exceed, the applicable time. If an ongoing radiological release is detected and the release start time is unknown, it should be assumed that the release duration specified in the IC/EAL has been exceeded, absent data to the contrary.A planned work activity that results in an expected event or condition which meets or exceeds an EAL does not warrant an emergency declaration provided that 1) the activity proceeds as planned and 2) the plant remains within the limits imposed by the operating license. Such activities include planned work to test, manipulate, repair, maintain or modify a system or component.
In these cases, the controls associated with the planning, preparation and execution of the work will ensure that compliance is maintained with all aspects of the operating license provided that the activity proceeds and concludes as expected.
Events or conditions of this type may be subject to the reporting requirements of 10 CFR 50.72.The assessment of some EALs is based on the results of analyses that are necessary to ascertain whether a specific EAL threshold has been exceeded (e.g., gaseous and liquid effluent sampling, etc.); the EAL and/or the associated basis discussion will identify the necessary analysis.
In these cases, the declaration period starts with the availability of the analysis results that show the threshold to be exceeded (i.e., this is the time that the EAL information is first available).
Permanently Defueled EAL Technical Bases Vermont Yankee Nuclear Power Station Rev. 0 Page 7 of 52 While the EALs have been developed to address a full spectrum of possible events and conditions which may warrant emergency classification, a provision for classification based on operator/management experience and judgment is still necessary.
The NEI 99-01 scheme provides the Emergency Director with the ability to classify events and conditions based upon judgment using EALs that are consistent with the ECL definitions (refer to PD-HU3 and PD-HA3). The Emergency Director will need to determine if the effects or consequences of the event or condition reasonably meet or exceed a particular ECL definition.
4.2 Classification
Methodology To make an emergency classification, the user will compare an event or condition (i.e., the relevant plant indications and reports) to an EAL(s) and determine if the EAL has been met or exceeded.
The evaluation of an EAL(s) must be consistent with the Notes. If an EAL has been met or exceeded, then the IC is considered met and the associated ECL is declared in accordance with plant procedures.
When assessing an EAL that specifies a time duration for the off-normal condition, the EAL time duration runs concurrently with the emergency notification time duration.4.3 Classification of Multiple Events and Conditions When multiple emergency events or conditions are present, the user will identify all met or exceeded EALs. The highest applicable ECL identified during this review is declared.
For example:* If an Unusual Event EAL and an Alert EAL are met, an Alert should be declared.There is no "additive" effect from multiple EALs meeting the same ECL. For example: 0 If two Alert EALs are met, an Alert should be declared.Related guidance concerning classification of rapidly escalating events or conditions is provided in Regulatory Issue Summary (RIS) 2007-02, "Clarification of NRC Guidance for Emergency Notifications During Quickly Changing Events." 4.4 Classification of Imminent Conditions Although EALs provide specific thresholds, the Emergency Director must remain alert to events or conditions that could lead to meeting or exceeding an EAL within a relatively short period of time (i.e., a change in the ECL is IMMINENT).
If, in the judgment of the Emergency Director, meeting an EAL is IMMINENT, the emergency classification should be made as if the EAL has been met. While applicable to all emergency classification levels, this approach is particularly important at the higher emergency classification level since it provides additional time for implementation of protective measures.4.5 Emergency Classification Level Upgrading and Downgrading An ECL may be downgraded when the event or condition that meets the highest IC and EAL no longer exists, and other site-specific downgrading requirements are met. If downgrading the ECL Permanently Defueled EAL Technical Bases Vermont Yankee Nuclear Power Station Rev. 0 Page 8 of 52 is deemed appropriate, the new ECL would then be based on a lower applicable IC(s) and EAL(s). The ECL may also simply be terminated.
The following approach to downgrading or terminating an ECL is recommended:
ECL Action When Condition No Longer Exists Unusual Event Terminate the emergency in accordance with plant procedures Alert Downgrade or terminate the emergency in accordance with plant procedures.
As noted above, guidance concerning classification of rapidly escalating events or conditions is provided in RIS 2007-02.4.6 Classification of Short-Lived Events Event-based Ils and EALs define a variety of specific occurrences that have potential or actual safety significance.
By their nature, some of these events may be short-lived and, thus, over before the emergency classification assessment can be completed.
If an event occurs that meets or exceeds an EAL, the associated ECL must be declared regardless of its continued presence at the time of declaration.
Examples of such events would be an earthquake or an explosion.
4.7 Classification
of Transient Conditions Many of the ICs and/or EALs contained in this document employ time-based criteria.
These criteria will require that the IC/EAL conditions be present for a defined period of time before an emergency declaration is warranted.
In cases where no time-based criterion is specified, it is recognized that some transient conditions may cause an EAL to be met for a brief period of time (e.g., a few seconds to a few minutes).
The following guidance should be applied to the classification of these conditions.
EAL momentarily met during expected plant response -In instances where an EAL is briefly met during an expected (normal) plant response, an emergency declaration is not warranted provided that associated systems and components are operating as expected, and operator actions are performed in accordance with procedures.
EAL momentarily met but the condition is corrected prior to an emergency declaration
-If an operator takes prompt manual action to address a condition, and the action is successful in correcting the condition prior to the emergency declaration, then the applicable EAL is not considered met and the associated emergency declaration is not required.It is important to stress that the emergency classification assessment period is not a "grace period" during which a classification may be delayed to allow the performance of a corrective action that would obviate the need to classify the event; emergency classification assessments must be deliberate and timely, with no undue delays.Permanently Defueled EAL Technical Bases Vermont Yankee Nuclear Power Station Rev. 0 Page 9 of 52 4.8 After-the-Fact Discovery of an Emergency Event or Condition In some cases, an EAL may be met but the emergency classification was not made at the time of the event or condition.
This situation can occur when personnel discover that an event or condition existed which met an EAL, but no emergency was declared, and the event or condition no longer exists at the time of discovery.
This may be due to the event or condition not being recognized at the time or an error that was made in the emergency classification process.In these cases, no emergency declaration is warranted; however, the guidance contained in NUREG-1 022, "Event Report Guidelines 10 CFR 50.72 and 50.73," is applicable.
Specifically, the event should be reported to the NRC in accordance with 10 CFR § 50.72 within one hour of the discovery of the undeclared event or condition.
The licensee should also notify appropriate State and local agencies in accordance with the agreed upon arrangements.
4.9 Retraction
of an Emergency Declaration Guidance on the retraction of an emergency declaration reported to the NRC is discussed in NUREG-1022.

Total Effective Dose Equivalent Definitions The following definitions are taken from Title 10, Code of Federal Regulations, and related guidance documents.
Alert Events are in progress or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant or a security event that involves probable life Permanently Defueled EAL Technical Bases Vermont Yankee Nuclear Power Station Rev. 0 Page 11 of 52 threatening risk to site personnel or damage to site equipment because of HOSTILE ACTION.Any releases are expected to be limited to small fractions of the EPA PAG exposure levels.Unusual Event Events are in progress or have occurred which indicate a potential degradation of the level of safety of the plant or indicate a security threat to facility protection has been initiated.
No releases of radioactive material requiring offsite response or monitoring are expected unless further degradation of safety systems occurs.The following are key terms necessary for overall understanding the NEI 99-01 emergency classification scheme.Emergency Action Level (EAL): A pre-determined, site-specific, observable threshold for an Initiating Condition that, when met or exceeded, places the plant in a given emergency classification level.Emergency Classification Level (ECL): One of a set of names or titles established by the US Nuclear Regulatory Commission (NRC) for grouping off-normal events or conditions according to (1) potential or actual effects or consequences, and (2) resulting onsite and offsite response actions. The ECLs, in ascending order of severity, are: " Unusual Event" Alert Emergency Action Levels A pre-determined, site-specific, observable threshold for an Initiating Condition that, when met or exceeded, places the plant in a given emergency classification level.Initiating Condition (IC)An event or condition that aligns with the definition of one of the two emergency classification levels by virtue of the potential or actual effects or consequences.
Selected terms used in Initiating Condition and Emergency Action Level statements are set in all capital letters (e.g., ALL CAPS). These words are defined terms that have specific meanings as used in this document.
The definitions of these terms are provided below.CONFINEMENT BOUNDARY The barrier(s) between areas containing radioactive substances and the environment.
EXPLOSION A rapid, violent and catastrophic failure of a piece of equipment due to combustion, chemical reaction or over pressurization.
A release of steam (from high energy lines or components) or an electrical component failure (caused by short circuits, grounding, arcing, etc.) should not Permanently Defueled EAL Technical Bases Vermont Yankee Nuclear Power Station Rev. 0 Page 12 of 52 automatically be considered an explosion.
Such events may require a post-event inspection to determine if the attributes of an explosion are present.FIRE Combustion characterized by heat and light. Sources of smoke such as slipping drive belts or overheated electrical equipment do not constitute FIRES. Observation of flame is preferred but is NOT required if large quantities of smoke and heat are observed.HOSTAGE A person(s) held as leverage against the station to ensure that demands will be met by the station.HOSTILE ACTION An act toward a NPP or its personnel that includes the use of violent force to destroy equipment, take HOSTAGES, 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 overall intent may be included.
HOSTILE ACTION should not be construed to include acts of civil disobedience or felonious acts that are not part of a concerted attack on the NPP. 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).HOSTILE FORCE One or more individuals who are engaged in a determined assault, overtly or by stealth and deception, equipped with suitable weapons capable of killing, maiming, or causing destruction.
IMMINENT The trajectory of events or conditions is such than an EAL will be met within a relatively short period of time regardless of mitigation or corrective actions.INDEPENDENT SPENT FUEL STORAGE INSTALLATION (ISFSI)A complex that is designed and constructed for the interim storage of spent nuclear fuel and other radioactive materials associated with spent fuel storage.NORMAL LEVELS As applied to radiological IC/EALs, the highest reading in the past twenty-four hours excluding the current peak value.OWNER CONTROLLED AREA The area outside the Protected Area, owned by Entergy.Permanently Defueled EAL Technical Bases Vermont Yankee Nuclear Power Station Rev. 0 Page 13 of 52 PROJECTILE An object directed toward a NPP that could cause concern for its continued operability, reliability, or personnel safety.PROTECTED AREA An area which normally encompasses all controlled areas within the security protected area fence as depicted in Drawing 5920-13013, Protected Area Fence.SECURITY CONDITION Any Security Event as listed in the approved security contingency plan that constitutes a threat/compromise to site security, threat/risk to site personnel, or a potential degradation to the level of safety of the plant. A SECURITY CONDITION does not involve a HOSTILE ACTION.UNPLANNED A parameter change or an event that is not 1) the result of an intended evolution or 2) an expected plant response to a transient.
The cause of the parameter change or event may be known or unknown.VISIBLE DAMAGE Damage to a component or structure that is readily observable without measurements, testing, or analysis.
The visual impact of the damage is sufficient to cause concern regarding the operability or reliability of the affected component or structure.

For development, it was assumed that the plant had operated under a 10 CFR § 50 license and that the operating company has permanently ceased plant operations.
Further, the company intends to store the spent fuel within the plant for some period of time.When in a permanently defueled condition, the plant licensee typically receives approval from the NRC for exemption from specific emergency planning requirements.
These exemptions reflect the lowered radiological source term and risks associated with spent fuel pool storage relative to reactor at-power operation.
Source terms and accident analyses associated with plausible accidents are documented in the station's Final Safety Analysis Report (FSAR), as updated. As a result, each licensee will need to develop a site-specific emergency classification scheme using the NRC-approved exemptions, revised source terms, and revised accident analyses as documented in the station's FSAR.Recognition Category PD uses the same ECLs as operating reactors; however, the source term and accident analyses typically limit the ECLs to an Unusual Event and Alert. The Unusual Event ICs provide for an increased awareness of abnormal conditions while the Alert ICs are specific to actual or potential impacts to spent fuel. The source terms and release motive forces associated with a permanently defueled plant would not be sufficient to require declaration of a Site Area Emergency or General Emergency.
A permanently defueled station is essentially a spent fuel storage facility with the spent fuel is stored in a pool of water that serves as both a cooling medium (i.e., removal of decay heat) and shield from direct radiation.
These primary functions of the spent fuel storage pool are the focus of the Recognition Category PD ICs and EALs. Radiological effluent IC and EALs were included to provide a basis for classifying events that cannot be readily classified based on an observable events or plant conditions alone.Appropriate ICs and EALs from Recognition Categories A, C, F, H, and S were modified and included in Recognition Category PD to address a spectrum of the events that may affect a spent fuel pool. The Recognition Category PD ICs and EALs reflect the relevant guidance in this document (e.g., the importance of avoiding both over-classification and under-classification).
Nonetheless, each licensee will need to develop their emergency classification scheme using the NRC-approved exemptions, and the source terms and accident analyses specific to the licensee.
Security-related events will also need to be considered.

It includes any gaseous or liquid radiological release, monitored or un-monitored, including those for which a radioactivity discharge permit is normally prepared.Nuclear power plants incorporate design features intended to control the release of radioactive effluents to the environment.
Further, there are administrative controls established to prevent unintentional releases, and to control and monitor intentional releases.
The occurrence of an extended, uncontrolled radioactive release to the environment is indicative of degradation in these features and/or controls.Radiological effluent EALs are also included to provide a basis for classifying events and conditions that cannot be readily or appropriately classified on the basis of plant conditions alone. The inclusion of both plant condition and radiological effluent EALs more fully addresses the spectrum of possible accident events and conditions.

If the effluent flow past an effluent monitor is known to have stopped Vermont Yankee Nuclear Power Station Permanently Defueled EAL Technical Bases Rev. 0 Page 18 of 52 Attachment 1 -Recognition Category PD EAL Bases due to actions to isolate the release path, then the effluent monitor reading is no longer valid for classification purposes.Releases should not be prorated or averaged.
For example, a release exceeding 4 times release limits for 30 minutes does not meet the EAL.EAL PD-AU 1.1 addresses radioactivity releases that cause effluent radiation monitor readings to exceed 2 times the limit established by a radioactivity discharge permit. This EAL will typically be associated with planned batch releases from non-continuous release pathways (e.g., radwaste, waste gas).The high alarm setpoint for the Stack Gas Monitor RM-17-156/157 (Gas-1 or Gas-2) is established to ensure the ODCM release limits are not exceeded. (Reference 3)In a permanently shutdown and defueled condition, the only credible scenario for releasing gas would be to damage spent fuel during handling.The high alarm setpoint for SW Discharge Hdr Discharge Monitor (RM-1 7-351) is established to ensure the ODCM release limits are not exceeded.

Vermont Yankee Basis: This EAL addresses a release of gaseous or liquid radioactivity that results in detectable levels offsite that are below 1% of the EPA PAGs and reflects the condition of an uncontrolled release of gaseous or liquid radioactivity that results in detectable levels at the site boundary.
It includes both monitored and un-monitored releases.
Releases of this magnitude represent an actual or potential substantial degradation of the level of safety of the plant as indicated by a radiological release that could potentially exceed regulatory limits (e.g., a significant uncontrolled release).With VY permanently shutdown, the only radionuclide of any significance available to be released in gaseous form is the noble gas Kr-85. Kr-85 decays emitting a low abundance gamma and is therefore not a significant contributor to TEDE.The gaseous release portion of this EAL is not based on any particular dose value, but rather on effluent radiation monitor readings equivalent to 90% of of the full scale reading of the monitors (Reference 11).The liquid release portion of this EAL is based on a counts per second value equivalent to 10 mrem TEDE (Reference 11).Vermont Yankee Nuclear Power Station Permanently Defueled EAL Technical Bases Rev. 0 Page 22 of 52 Attachment 1 -Recognition Category PD EAL Bases Radiological effluent EALs provide a basis for classifying events and conditions that cannot be readily or appropriately classified on the basis of plant conditions alone. The inclusion of both plant condition and radiological effluent EALs more fully addresses the spectrum of possible accident events and conditions.
Classification based on effluent monitor readings assumes that a release path to the environment is established.
If the effluent flow past an effluent monitor is known to have stopped due to actions to isolate the release path, then the effluent monitor reading is no longer valid for classification purposes.In a permanently shutdown and defueled condition, the only credible scenario for releasing gas would be to damage spent fuel during handling.Vermont Yankee Basis Reference(s):

ARM #14 Rx Bldg West Refuel" ARM #15 Spent Fuel Floor Vermont Yankee Basis: This IC addresses elevated plant radiation levels caused by a decrease in water level above irradiated (spent) fuel or other UNPLANNED events. The increased radiation levels are indicative of a minor loss in the ability to control radiation levels within the plant or radioactive materials.
Either condition is a potential degradation in the level of safety of the plant.A water level decrease will be primarily determined by indications from available level instrumentation.
Other sources of level indications may include reports from plant personnel or video camera observations (if available).
A significant drop in the water level may also cause an increase in the radiation levels of adjacent areas that can be detected by monitors in those locations.
The effects of planned evolutions should be considered.
Note that PDAU2.1 is applicable only in cases where the elevated reading is due to an UNPLANNED water level drop.Loss of inventory from the spent fuel pool may reduce water shielding above spent fuel and cause unexpected increases in plant radiation.

Areas that meet this threshold include the Control Room. There are no permanently installed Control Room area radiation monitors that may be used to assess this EAL threshold.
Therefore these thresholds must be assessed via local radiation survey (Reference 1).An emergency declaration is not warranted if any of the following conditions apply: " The increased radiation levels are a result of a planned activity that includes compensatory measures which address the temporary inaccessibility of a room or area (e.g., radiography, spent filter or resin transfer, etc.)."

The Alert declaration will also heighten the awareness of OROs, allowing them to be better prepared should it be necessary to consider further actions.This IC does not apply to incidents that are accidental events, acts of civil disobedience, or otherwise are not a HOSTILE ACTION perpetrated by a HOSTILE FORCE. Examples include the crash of a small aircraft, shots from hunters, physical disputes between employees, etc.Reporting of these types of events is adequately addressed by other EALs, or the requirements of 10 CFR 73.71 or 10 CFR 50.72.PD-HAI.1 is applicable for any HOSTILE ACTION occurring, or that has occurred, in the OWNER CONTROLLED AREA. This includes any action directed against an ISFSI that is located within the OWNER CONTROLLED AREA.The NRC HOO will communicate to the licensee if the threat involves an aircraft.
The status and size of the plane may be provided by NORAD through the NRC.In some cases, it may not be readily apparent if an aircraft impact within the OWNER CONTROLLED AREA was intentional (i.e., a HOSTILE ACTION). It is expected, although not certain, that notification by an appropriate Federal agency to the site would clarify this point. In this case, the appropriate federal agency is intended to be NORAD, FBI, FAA or NRC.

Hazardous event affecting equipment necessary for spent fuel cooling.EAL: PD-HU2.1 a. The occurrence of ANY of the following hazardous events: " Seismic Event (earthquake)
- Internal or external flooding event" River water level >250 ft. MSL (plant grade)* Intake water level < 210 ft. MSL" High winds or tornado strike* FIRE* EXPLOSION" Other events with similar hazard characteristics as determined by the Shift Manager AND b. The event has damaged at least one train of a system needed for spent fuel cooling.AND c. The damaged train(s) cannot, or potentially cannot, perform its designed function based on EITHER: 0 Indications of degraded performance e VISIBLE DAMAGE Vermont Yankee Basis: This IC addresses a hazardous event that causes damage to at least one train of a system needed for spent fuel cooling. The Service Water System and SFP Cooling systems are the systems necessary to maintain SFP cooling. The damage must be of sufficient magnitude that the system(s) train cannot, or potentially cannot, perform its design function.
This condition reduces the margin to a loss or potential loss of the fuel clad barrier, and therefore represents a potential degradation of the level of safety of the plant.Plant Grade is 250 ft. MSL. The maximum water level experienced at the site was 231.4 ft. MSL.The Maximum Probable Flood is 252.5 ft. MSL. Since the entrances to all structures containing equipment necessary for cooling are at elevation 252.5 ft. MSL, they are protected against the MPF. However, water level in excess of plant grade may result in a loss of accessibility.(References 1, 2, 3) Gradients, ranging from 248 feet to 254 feet, are available on the north side of the intake structure wall to assist in classifying this event.Vermont Yankee Nuclear Power Station Permanently Defueled EAL Technical Bases Rev. 0 Page 44 of 52 Attachment 1 -Recognition Category PD EAL Bases Intake water level less than 210 feet indicates low river water conditions which may threaten the operability of the spent fuel pool cooling system. Intake Bay Level Gauge LI-104-9 on Control Room Panel CRP-9-6 as well as direct observation at the intake structure can be used to ascertain this initiating condition threshold.
For EAL PD-HU2.1a, the last bullet is not intended to address component failures within the system such as pump bearing failures, electrical grounds or shorts in a pump, failure of valves, etc. Declaration of an event due to the failure of a component would be based on PD-SU1.1.For EAL PD-HU2.1c, the first bullet addresses damage to a system that is in service/operation since indications for it will be readily available.
For EAL PD-HU2.1c, the second bullet addresses damage to a system that is not in service/operation or readily apparent through indications alone. Operators will make this determination based on the totality of available event and damage report information.
This is intended to be a brief assessment not requiring lengthy analysis or quantification of the damage.Escalation of the emergency classification level could, depending upon the event, be based on any of the Alert ICs; PD-AA1, PD-AA2, PD-HA1 or PD-HA3.Vermont Yankee Basis Reference(s):

No releases of radioactive material requiring offsite response or monitoring are expected unless further degradation of safety systems occurs.Vermont Yankee Basis: This IC addresses unanticipated conditions not addressed explicitly elsewhere but that warrant declaration of an emergency because conditions exist which are believed by the Emergency Director to fall under the emergency classification level description for an Unusual Event.The Emergency Director is the designated onsite individual having the responsibility and authority for implementing the Vermont Yankee Emergency Plan. The Shift Manager (SM)initially acts in the capacity of the Emergency Director and takes actions as outlined in the Emergency Plan implementing procedures.
If required by the emergency classification or if deemed appropriate by the Emergency Director, emergency response personnel are notified and instructed to report to their emergency response locations.
In this manner, the individual usually in charge of activities in the Control Room is responsible for initiating the necessary emergency response, but plant management is expected to manage the emergency response as soon as available to do so in anticipation of the possible wide-ranging responsibilities associated with managing a major emergency (Reference 1).Vermont Yankee Basis Reference(s):

Vermont Yankee Technical Specifications Vermont Yankee Nuclear Power Station Permanently Defueled EAL Technical Bases Rev. 0 Page 48 of 52 Attachment 2 -Recognition Category E EAL Basses 8.2 Attachment 2 -Recognition Category E EAL Basis Recognition Category E provides a set of ICs/EALs for an ISFSI. An ISFSI is a complex that is designed and constructed for the interim storage of spent nuclear fuel and other radioactive materials associated with spent fuel storage. A significant amount of the radioactive material contained within a cask must escape its packaging and enter the biosphere for there to be a significant environmental effect resulting from an accident involving the dry storage of spent nuclear fuel. Formal offsite planning is not required because the postulated worst-case accident involving an ISFSI has insignificant consequences to the public health and safety.An Unusual Event is declared on the basis of the occurrence of an event of sufficient magnitude that a loaded cask confinement boundary is damaged or violated.
This includes classification based on a loaded fuel storage cask confinement boundary loss leading to the degradation of the fuel during storage or posing an operational safety problem with respect to its removal from storage.Vermont Yankee Nuclear Power Station Permanently Defueled EAL Technical Bases Rev. 0 Page 49 of 52 Attachment 2 -Recognition Category E EAL Basses Table E-1: Recognition Category "E" Initiating Condition Matrix UNUSUAL EVENT E-HU1 Damage to a loaded cask CONFINEMENT BOUNDARY.Vermont Yankee Nuclear Power Station Permanently Defueled EAL Technical Bases Rev. 0 Page 50 of 52.
Attachment 2 -Recognition Category E EAL Basses E -Independent Spent Fuel Storage Istallation Damage to a loaded cask CONFINEMENT BOUNDARY Category: Initiating Condition:
EAL: E-HU1.1 Damage to a loaded cask CONFINEMENT BOUNDARY as indicated by a radiation reading greater than two times the ISFSI Technical Specification allowable levels.Two times the ISFSI Technical Specification allowable levels equate to: a 2.88 mR/hr on the top of the overpack or* 1.90 mR/hr on the side of the overpack, excluding inlet and outlet ducts.Vermont Yankee Basis: This IC addresses an event that results in damage to the CONFINEMENT BOUNDARY of a storage cask containing spent fuel. It applies to irradiated fuel that is licensed for dry storage beginning at the point that the loaded storage cask is sealed. The issues of concern are the creation of a potential or actual release path to the environment, degradation of one or more fuel assemblies due to environmental factors, and configuration changes which could cause challenges in removing the cask or fuel from storage.The existence of "damage" is determined by radiological survey. The Technical Specification multiple of two times is used here to distinguish between non-emergency and emergency conditions.
The emphasis for this classification is the degradation in the level of safety of the spent fuel cask and not the magnitude of the associated dose or dose rate. It is recognized that in the case of extreme damage to a loaded cask, the fact that the dose rate limit is exceeded may be determined based on measurement of a dose rate at some distance from the cask.Minor surface damage that does not affect the storage cask boundary is excluded from the scope of this EAL.Two times the ISFSI Technical Specification allowable levels equate to: a 2.88 mR/hr on the top of the overpack or* 1.90 mR/hr on the side of the overpack, excluding inlet and outlet ducts.
