Attachment 1 Letter Number 2.18.063 Response to Request for Additional Information - License Amendment Request to Revise the Pilgrim Nuclear Power Station Emergency Plan and Emergency Action Level Scheme to Address the Permanently Defueled Condition I

Letter Number 2.18.063 Page 1 of 3 A U.S. Nuclear Regulatory Commission (NRC) request for additional information (RAI) regarding a license amendment request to revise the Pilgrim Nuclear Power Station (PNPS)

Site Emergency Plan (SEP) was received by Entergy Nuclear Operations, Inc. (ENO) via electronic mail (email) dated October 12, 2018. ENO responses to the RAI request are provided below.

NRCREQUEST By application dated August 1, 2018, (Agencywide Documents Access and Management System (ADAMS) Accession No. ML 18218184), Entergy Nuclear Operations,' Inc., submitted changes to the site emergency plan (SEP) and emergency action level (EAL) scheme for the Pilgrim Nuclear Power Station (PNPS) for Commission review and prior approval pursuant to Section 50.90 of Title 10 of the Code of Federal Regulations (10 CFR). The proposed changes would revise the SEP and EAL scheme to reflect a permanently defueled condition.

The NRC staff has reviewed the licensee's submittal and determined that additional information is required to enable the NRG staff to make an independent assessment regarding its technical review.

NRC RAI-PNPS-1 Evaluation Criterion E.4 in Attachment 1 to NSIRIDPR-ISG-02 provides guidance on the contents of emergency messages based on the permanently shutdown .and defueled condition of the facility, and includes that licensee will communicate a "[m.] request for any needed onsite support by offsite organizations." However, the content of messages, as described in Section 5. 1.2, "Commonwealth and Local Government Notification," to Enclosure 1 of Entergy's August 1, 2018 letter, does not appear to address this criterion.

Please describe the method being used by the licensee for conveying this information to State and local organizations, or basis for not addressing this criterion in emergency message content.

ENO Response to RAI-PNPS-1 The commercial telephone network and the emergency messages described in Section 5.1.2 of the Permanently Defueled Emergency Plan (PDEP), "Commonwealth and Local Government Notification," are used to request any needed onsite support from offsite organizations. The list of information contained in the emergency messages, provided in Section 5.1.2 of the proposed PDEP, has been revised to specifically include a request for any needed support from offsite organizations. The revisions to the proposed PDEP are included in Attachment 2 of this response.

NRC RAI-PNPS-2 Evaluation Criteria N.1.a and bin Attachment 1 to NSIRIDPR-ISG-02 state, in part:

a. An exercise is an event that tests the integrated capability and a major portion of the basic elements existing within emergency preparedness plans and organizations.

Exercises shall be conducted as set forth in 10 CFR 50, as exempted, and in

Letter Number 2.18.063 Page 2 of 3 accordance with applicable portion to Section JV. G (Challenging Drills and Exercises) to NSIRIDPR-/SG-01, "Emergency Planning for Nuclear Power Plants."

b. The scenario should be varied from year to year such that all major elements of the plans and preparedness organizations are tested.

Please explain why there is no provision in Section 14.0, "Exercises and Drills," to Enclosure 1, page 25, of Entergy's August 1, 2018 letter, for exercises and drills being conducted as set forth in 10 CFR 50, and in accordance with applicable portion to Section JV.G to NSIRIDPR-

/SG-01, for the scenario to be varied from year to year.

ENO Response to RAI-PNPS-2 PNPS conducts exercises and drills in accordance with 10 CFR Part 50 and will continue to conduct exercises and drills as set forth in 10 CFR Part 50, as exempted, including the provision that exercise scenarios be varied from year to year, to the extent practicable, such that all major elements of the plans and preparedness organizations are tested. Section 14.0 of the PDEP, "Exercises and Drills," is revised to clarify that exercise and drills will be conducted as set forth in 10 CFR Part 50, and in accordance with applicable portion to Section IV.G to NSIR/DPR-ISG-01, for the scenario to be varied from year to year. The revisions to the proposed PDEP I

are included in Attachment 2 of this response.

NRC RAI-PNPS-3 Nuclear Energy Institute (NE/) 99-01, Revision 6, "Development of Emergency Action Levels for Non-Passive Reactors," dated November 2012 (ADAMS Accession Number ML12326A805) was endorsed by the NRG by letter dated March 28, 2013 (ADAMS Accession Number ML12346A463).

In "Recognition Category PD EAL Bases," to Attachment 1, page 21, PD-AA 1, EAL 3 states:

"Analysis of a liquid effluent sample indicates a concentration or release rate that would result in doses greater than 10 mrem TEDE or 50 mrem thyroid COE at or beyond the site boundary." However, it does not include the following NE/ language - "for one hour of exposure," nor is any justification provided for the difference.

I Please explain why the reference NE/ language is not included.

ENO Response to RAI-PNPS-3 The referenced NEI language was unintentionally omitted and is added to the Permanently Defueled Emergency Action Level Technical Bases Document (Enclosure 2 of the LAR).

These revisions are included in Attachment 3 of this response. Conforming changes are also made to the Permanently Defueled Emergency Action Level Scheme Matrix (Enclosure 3 of the LAR) and the Comparison Matrix for Permanently Defueled EALs Based on NEI 99-01, "Development of Emergency Action Levels for Non-Passive Reactors," Revision 6 (Attachment 2 of the LAR) and are included in Attachments 4 and 5 of this response, respectively.

Letter Number 2.18.063 Page 3 of 3 NRC RAI-PNPS-4 In "Recognition Category PD EAL Bases," to Attachment 1, page 28, PD-HU1, the following NE/ language is absent: "Escalation of the emergency classification level would be via IC PD-HA 1," nor is any justification provided for the difference.

Please explain why the reference NE/ language is not included.

ENO Response to RAI-PNPS-4 The basis language provided in NEI 99-01, "Development of Emergency Action Levels for Non-Passive Reactors," Revision 6 (NEI 99-01) for Permanently Defueled Emergency Action Level (PD EAL) PD-HU1 includes the statement, "Security events assessed as HOSTILE ACTIONS are classifiable under IC PD-HA 1." This language is present in the PNPS Basis for PD-HU1. The statement, "Escalation of the emergency classification level would be via IC PD-HA1," appeared redundant, and was not included in the PNPS Basis. The Comparison Matrix for Permanently Defueled EALs Based on NEI 99-01, "Development of Emergency Action Levels for Non-Passive Reactors," Revision 6, included as Attachment 2 of the LAR, included a Comparison column that stated that PNPS site-specific basis information was included.

However, omission of this statement was not specifically addressed.

To better align with NEI 99-01, the referenced NEI language is added to the Permanently Defueled Emergency Action Level Technical Bases Document (Enclosure 2 of the LAR).

These revisions are included in Attachment 3 of this response. Conforming changes are also made to Attachment 2 of the LAR and included in Attachment 5 of this response.

Attachment 2 Letter Number 2.18.063 Revised Pages of the PNPS Permanently Defueled Emergency Plan (Enclosure 1 of the LAR)

PNPS PERMANENTLY DEFUELED EMERGENCY PLAN 5.1.1 . Emergency Response Organization Activation On-site staff are informed of an emergency condition through the use of the facility 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 ERO positions are not on-site at the time an emergency is declared, they may be contacted by commercial telephone including land lines and/or wirel~ss 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.

5.1.2 Commonwealth and Local Government Notification Notification to the responsible Commonwealth and Town of Plymouth authorities is required within 60 minutes of the emergency classification.

The commercial telephone network serves as the primary means to provide emergency notification to Commonwealth and Town of Plymouth agencies. It is used to provide initial and updated notifications and for general information flow between these agencies.

PNPS, in coordination with the Commonwealth of Massachusetts, have established the contents of the initial emergency messages to be sent from PNPS in the event an emergency is declared. These messages contain the following information if it is known and appropriate:

  • Notification Type, i.e. "This is a Drill" or "This is an Actual Event."
  • Identity of caller and receiver of call
  • The date and time of classification and notification
  • Emergency classification
  • EAL identification and whether a release is in progress
  • Wind direction and speed
  • Response actions underway
  • Request for any needed onsite support by offsite organizations
  • Prognosis for.worsening or termination of event based on facility' information In the event the commercial telephone system is unavailable, wireless communications can be used to make emergency notifications. Ir:,

addition, electronic means may be used to transmit the notification message.

13 Revision TBD

PNPS PERMANENTLY DEFUELED EMERGENCY PLAN

  • Documenting all proceedings of the event and reviewing the effectiveness of the emergency organization in reducing public hazard and plant damage When plant conditions allow a transition from the emergency phase to the recovery phase, the Emergency Director conducts a plant emergency management meeting to discuss the recoverY organization. The actions taken by this organization concerning termination of the emergency proceeds in accordance with a recovery plan developed specifically for the accident conditions.

14.0 EXERCISES AND DRILLS Periodic exercises are conducted to evaluate major portions of emergency response capabilities. Periodic drills are conducted to develop and maintain key emergency response skills. Deficiencies as a result of exercises or drills are identified and corrected.

Exercises and drills shall be conducted as set forth in 10 CFR Part 50, as exempted, and in accordance with applicable portion to Section IV.G to NSIR/DPR-ISG-01, "Emergency Planning for Nuclear Power Plants."

14.1 Exercises Biennial exercises shall be conducted to test the timing and content of implementing procedures and methods and to ensure that emergency personnel are familiar with their duties. Offsite organizations are offered the opportunity to participate to the extent assistance would be expected during an emergency declaration. However, participation by offsite organizations is not required, nor are offsite response organizations evaluated.

14.2 Drills Communication checks with offsite agencies, fire drills, medical drills, radiological monitoring drills and health physics drills are performed as indicated in the following sections.

14.2.1 Medical Drills Medical emergency drills, involving an individual who is simulated to be injured and contaminated, are conducted at least annually. The local ambulance service and Beth Israel Deaconess Hospital - Plymouth are invited to participate in an annual exercise and/or scheduled drill(s) to demonstrate and practice the receipt and treatment of contaminated patients. Involvement by hospital and medical transport services may be included as part of any drill or exercise.

14.2.2 Accountability Drills An accountability drill shall be conducted annually. This drill shall include identifying the locations of all personnel onsite. This drill can be performed as part of any drill or exercise.

25 Revision TBD

PNPS PERMANENTLY DEFUELED EMERGENCY PLAN

  • Objective(s)
  • Date, time period, place and participating organizations
  • Simulation lists
  • Timeline of real and simulated events
  • A narrative summary
  • List of controllers and participants The scenario varies year to year. Within an eight-year period, the scenario content is varied to test all the major elements of the Emergency Preparedness Program.

The final scenario shall be approved by a designated member of senior facility management. Drill/Exercise confidentiality must always be maintained.

14.4 Critique/Evaluation Critiques will evaluate the participant's performance during a drill or exercise.

The ability of participants to self-evaluate weaknesses and identify areas of improvement is the key to successful exercise/drill conduct.

Exercise and drill performance objectives are evaluated against measurable demonstration criteria. As soon as possible following the conclusion of each drill/exercise, a critique, including participants, controllers, and evaluators, is conducted to evaluate the ability of the participants to meet the performance objectives. Deficiencies are identified and entered into the corrective action system.

A written report is prepared including the evaluation of designated objectives.

The report evaluates and documents the participants' response to the emergency situation. The report will also contain reference to corrective action and recommendations resulting from the drill/exercise.

15.0 RADIOLOGICAL EMERGENCY RESPONSE TRAINING Radiological emergency response training is provided to those who may be called on to assist in an emergency. PNPS Management is responsible to ensure all members of the Emergency Response Organization receive the required initial training and continuing training.

15.1 Emergency .Response Training The training program for ERO personnel is based on applicable requirements of Appendix E to 10 CFR Part 50 and position-specific responsibilities as defined in the PDEP. Emergency response personnel in the following categories receive initial training and annual retraining.

27 Revision TBD

Attachment 3 Letter Number 2.18.063 Revised Pages of the Permanently Defueled Emergency Action Level Technical Bases Document (Enclosure 2 of the LAR)

Attachment 1 Recognition Category PD EAL Bases

3. Analysis of a liquid effluent sample indicates a concentration or release rate that would result in doses greater than 10 mrem TEDE or 50 mrem thyroid COE at or beyond the site boundary for one hour of exposure .

. 4. Field survey results indicate EITHER of the follow ing at or beyond (site-specific dose receptor point):

(-

  • Closed window dose rates greater than 10 mR/h r expected to continue for 60 minutes or longer.
  • Analyses of field survey samples indicate thyroid COE greater than 50 mrem for one hour of inhalation.

This IC addresses a release of gaseous or liquid radio activity that results in projected or actual offsite doses greater than or equal to 1% of the EPA Protective Action Guides (PAGs). It includes both monitored and un-monito red releases. Releases of this magnitude represent an actual or potential substantia l degradation of the level of safety of the facility as indicated by a radiological release that significantly exceeds regulatory limits (e.g., a significant uncontrolled release).

Radiological effluent EALs are also included to provi de a basis for classifying events and conditions that cannot be readily or appropriately classified on the basis of facility conditions alone. The inclusion of both facility cond ition and radiological effluent EALs more fully addresses the spectrum of possible accid ent events and conditions.

The TEDE dose is set at 1% of the EPA PAG of 1,000 mrem while the 50 mrem thyroid COE was established in consideration of the 1:5 ratio of the EPA PAG for TEDE and thyroid COE.

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.

The radiation monitor that detects gaseous radio activity effluent release to the_

environment is the Reactor Building Ventilation Exha ust (RBVE) monitors RM-1705-32A/B on Panel C910 (ref .1 ).

Complete assumptions and inputs for these EAL thres hold values are documented from the calculation in PNPS082-CALC-001 Revision 0, PD-AAL Gaseous Effluent EAL Threshold (ref. 2).

The threshold of > 2. 75E5 is limited to a maximum value of 8E+5 cps to assure an on-scale readable value.
