Harris Nuclear Plant Pre-Submittal Meeting - November 8, 2018
License Amendment Request for Shearon Harris Nuclear Power Plant Emergency Plan Revision 2
Duke Energy Participants Jeff Robertson, Regulatory Affairs Manager David Thompson, Emergency Preparedness Corporate Manager Chuck Yarley, HNP Regulatory Affairs Engineer David Stih, HNP Emergency Preparedness Specialist 3
Summary 4
The LAR will revise the Emergency Plan as follows:
Currently per PLP-201 Revised PLP-201 TSC Exterior walls, roofs, and floor are built to Seismic Category 1, tornado, wind, and missile safety criteria.
Exterior walls, roof, and floor are designed and built to a nationally recognized building code Alerting, warning, and notification will be provided by sounding sirens, activation of tone-activated radios within five miles of the plant, and supplemented by announcements made through radio and television (EAS),
sound trucks, bullhorns, and knocking on doors.
Alerting, warning, and notification will be provided by sounding sirens and supplemented by announcements made through radio and television (EAS), sound trucks, bullhorns, and knocking on doors.
Background:
The Technical Support Center (TCS)
Located in the Fuel Handling Building Exterior walls generally built Seismic Category 1, tornado, wind, and missile safety-related criteria.
Interior Walls and Ceilings are built to the North Carolina Building Code.
There are roof and wall penetrations not built to nuclear safety-related criteria.
Background:
Currently, HNP ANS credits Sirens and Tone Alert Radios as primary.
Mobile Route Alerting is back-up.
Emergency Alert System (EAS) supplements both with notifications.
HNP supports Tone Alert Radios by:
Distribution to all residencies within 5 miles of the plant.
Yearly distribution of batteries.
Yearly guidance on purpose and operation.
Conducting annual testing and effectiveness surveys.
Background:
Original (pre-2008) ANS Design:
Used 69 Sirens Locations may be under 60 dBc FEMA approval was contingent on supplementing original design.
Current (Post-2008) ANS Design:
Uses 83 Sirens 60 dBc for essentially 100% population Supplemental system no longer needed.
FEMA, State, and county approval Req.
Proposed Changes:
For TSC:
The E-Plan will no longer state that the TSC is built to safety-related criteria.
Instead, E-Plan will state that the TSC is built to a nationally recognized building code.
8 For Tone Alert Radios:
The E-Plan will no longer include Tone Alert Radios as part of ANS.
Instead, E-Plan will rely on sirens only for primary alerting system.
Regulatory Guidance - TSC and ANS
10 CFR 50.54(q), Conditions of Licenses, Emergency Plans
10 CFR 50.47, Emergency Plans and 10 CFR 50, Appendix E, "Emergency Planning and Preparedness for Production and Utilization Facilities
NRC Regulatory Issue Summary 2005-02, Revision 1, Clarifying The Process For Making Emergency Plan Changes
NUREG-0654/FEMA-REP-1, Revision 1, Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants
NUREG-0696, Dated February 1981, Functional Criteria for Emergency Response Facilities
NUREG -0737 Supplement 1, Dated January 1983, Clarification of TMI Action Plan Requirements
FEMA-REP-10, Dated November 1985, Guide for the Evaluation of Alert and Notification Systems for Nuclear Power Plants, 9
Precedents The following LAR is an example of a recently approved Emergency Plan utilizing a siren-only ANS design:
Vogtle, Unit 3 and 4, 2017 - NRC agrees Tone Alert Radios no longer required per approved VEGP ANS design.
10
Conclusion LAR is required to correct nonconformance with TSC documentation.
The TSC design is robust, meets regulatory guidance to protect the public.
Change will also align ANS design with FEMA/Industry best practices.
Credits improved siren performance from 2008 ANS redesign.
Eliminates vulnerability to public and significant burden on the site.
Site and public coordination will no longer be required to distribute, install, and maintain Tone Alert Radios.
