Vogtle 3&4 Roadmap to Compliance Unit 3 MBDBE Project Milestone June 2019: Submit Communications Assessment (NTTF 9.3) NRC Deliverable / Inspection July 2019: 10CFR50.155 effective (est.) Vogtle 3&4 Site Milestone August 2019: OIP Submitted with six-month update EA-12-049 complete (4 months prior to Fuel Load)

Fuel Load 10CFR50.155 compliance @ fuel load Commercial Operation (COD) Unit 4 EA-12-049 complete (4 months prior to Fuel Load)

Submit FIP (60 days after U4 completion)

Fuel Load 10CFR50.155 compliance @ fuel load FLEX SER issued (est. 6 months after FIP)

Commercial Operation (COD)

FLEX/LOLA Inspections (~6 months after COD)

SNC Update - EA-12-051 Spent Fuel Pool Level Instrumentation (SFPLI)

• SER Issued (ML13329A878)

• SER Conclusions Basis:

• The licensees response to EA-12-051 is acceptable because, as described in APP-SFS-MSR-03, it includes provisions for SFP instrumentation arrangement, qualification, power sources, accuracy and display that are consistent with the requirements described in SECY-12-0025 and Commission Order EA-12-051.

• The proposed provisions for training related to the reliable SFP instrumentation are acceptable because they provide for the instrumentation to be maintained available and reliable through appropriate development and implementation of a training program including provisions for use of alternate power to the safety-related level instrument channels.

Focused Discussion: NTTF 9.3

• NTTF 9.3 Communication and Staffing Actions

• 50.54(f) Communications Assessment

• 50.54(f) Staffing Assessment

NTTF 9.3 Communications & Staffing Actions

• Operating Fleet in 2012:

• EP Rule issued in fall 2011, required staffing assessments per NEI 10-05 for single unit events

• Procedures and guidance addressed single unit events

• 50.54(f) Requested information on how sites would cope for an extended loss of AC power (ELAP) with existing procedures and guidance

• Majority of actions and vulnerabilities were within the first 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> of an event

• NRC Accepted a phased approach,

- Assessing current state with actions to cope with vulnerabilities

- Documenting capabilities post-FLEX

• Differs from Vogtle 3&4 FLEX program:

• AP1000 designed as stand alone Unit with separate control room staff and support equipment

• EP Rule effective with NEI 10-05 Study performed

• No interim actions needed since not operating yet

50.54(f) Communications Assessment

• Planned submittal to NRC in June 2019

• Similar in format to Vogtle 1&2 assessment (NL-12-2070)

• Portable handheld satellite phones for initial notification (housed in TSC/MCR)

• Utilize RapidCOM and RapidCase Satellite Communications equipment

- Timeline for RapidCOM allows Vogtle 1&2 FLEX deployment to take priority

• Design basis allows for required communication for off-site and select on-site locations

• Will Utilize Bullhorn/Self Mustering during an ELAP

50.54(f) Staffing Assessment

• Vogtle Electric Generating Plant - Units 3 and 4 60-Day Response to NRC Letter stated the Phase 1 & 2 staffing assessment will be completed prior to the full scale EP exercise which will be conducted prior to fuel load of Vogtle 3 (ML12131A540)

• Endorsed guidance NEI 12-01 states the Phase 1 staffing study for a Single Unit Plant is the NEI 10-05 study

• Until Vogtle 4 is operational, Vogtle 3 is considered a single unit plant

• Additionally, for a Multi-Unit site the Phase 1 study provides actions for vulnerabilities in the operating units

• Vogtle 3 &4 have no existing vulnerabilities

50.54(f) Staffing Assessment (contd)

• Proposal: Revise current commitment for NEI 12-01 Staffing Assessment from prior to Unit 3 fuel load (ML12131A540) to be prior to Unit 4 Fuel Load

• Conduct an NEI 12-01 Phase 2 Study to cover both Units 3&4

• Utilize the latest approved Emergency Plan Staffing at that time

• Justification

• AP1000 design requires minimal actions in first 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />

• NEI 12-01 Staffing Assessment concentrates primarily on first 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, with limited assessment from 6-24 hours, thus of little consequence in a 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> passive design

• Would utilize the proposed change to Fleet Emergency Plan Staffing

- Submission of 2019 assessment per FLEX 6-month update submittal (ML19056A206) would be invalidated
