SUMMARY

The U.S. Department of Homeland Security's (DHS) Federal Emergency Management Agency (FEMA) Region IX National Preparedness Division, Technological Hazards Branch, evaluated an Off-site Plume Phase exercise (PPX) on November 2, 2016, in the Emergency Planning Zone (EPZ) around the Diablo Canyon Power Plant (DCPP). Out-of-Sequence (OoS) Interviews were conducted on October 12-13, and November 3, 2016. The findings in this report contain the final FEMA evaluation results, from the DCPP PPX and OoS Interviews, with final determinations made by the FEMA Region IX Acting Regional Assistance Committee (RAC) Chair and approved by the FEMA Region IX Regional Administrator.

The purpose of the PPX is part of the Radiological Emergency Preparedness (REP) Program to assess the level of State and local Off-site Response Organizations (ORO) preparedness in response to a radiological incident at DCPP. The PPX was held in accordance with FEMA's policies and guidance concerning the implementation of State and local ORO Radiological Emergency Response Plans (RERP) and procedures.

The previous biennial exercise at DCPP was conducted on May 21, 2014, and the qualifying emergency preparedness exercise was conducted on August 19, 1981. The scenario and the Extent-of-Play (BOP) agreement was reviewed, and approved, by FEMA Region IX Acting RAC Chair prior to the scheduled date of the PPX. There were no Area Requiring Corrective Action (ARCA) or Planning Issues from previous PPXs that required correction.

There were no Level 1 or 2 Findings, or Planning Issues identified during the PPX. In Summary: The State and local ORO demonstrated that their plans and procedures can be adequately implemented, and that there is a continued reasonable assurance that measures can be taken to protect the health and safety of the public in the event of a radiological incident at DCPP. 6 Unclassified After Action Report/Improvement Plan Radiological Emergency Preparedness Program (REP) Diablo Canyon Power Plant SECTION 1: EXERCISE OVERVIEW 1.1 Exercise Details Exercise Name Diablo Canyon Power Plant Type of Exercise Plume Phase exercise Exercise Dates October 12 -13, and November 2 -3, 2016 Program U.S. Department of Homeland Security/FEMA REP Program Scenario Type Radiological Emergency

SUMMARY

2.1 Exercise

Purpose and Design The Federal Emergency Management Agency administers the REP Program pursuant to the regulations found in Title 44 Code of Federal Regulations (C.F.R.) § 350, 351and352 (October 2011) and the FEMA REP Program Manual, (January 2016). Title Emergency Management and Assistance, 44 C.F.R. § 350 (October 2011) codifies 16 Planning Standards that form the basis for radiological emergency response planning for licensees, State, local, and tribal governments impacted by the EPZs established for each nuclear power plant (NPP) site in the United States of America. One of the REP Program cornerstones established by these regulations is the biennial exercise of Off-site response capabilities.

During a biennial exercises, State and local governments demonstrate their abilities to implement their plans and procedures to protect the health and safety of the public in the event of a radiological incident at the nuclear plant. The results of this exercise, together with the review.of the RERPs and procedures, the verification of the periodic requirements (set forth in NUREG-0654/FEMA-REP-1) enable FEMA to provide a statement with transmission of this final After Action Report to the U.S. Nuclear Regulatory Commission, that State and local plans and preparedness are:

Adequate to protect the health and safety of the public living in the vicinity of the nuclear power facility; and

That appropriate protective measures can be implemented Off-site in the event of a radiological incident occurring at the nuclear power facility.

2.2 Exercise

Demonstration Criteria and Core Capabilities Plume Pathway exercises are conducted to provide FEMA the opportunity to evaluate and assess emergency plans and associated implementing procedures, and facilities and equipment, which would be used in a radiological incident occurring at the nuclear power facility.

Core Capabilities span three of five Mission Areas. Mission areas serve as an 14 Unclassified After Action Report/Improvement Plan Radiological Emergency Preparedness Program (REP) Diablo Canyon Power Plant aid in integration and coordination to achieve the goal of a secure and resilient nation. Core Capabilities directly involve more than one mission area and are listed within each Mission Area as appropriate.

The followillg are classifications of those Core Capabilities, with associated Mission Areas, and related REP Program demonstration criteria evaluated during the PPX and OoS Interviews:

Protection Mission Area Core Capabilities are the product of diverse activities, and include the capabilities to safe guard the homeland against acts of terrorism and man-made or natural disasters.

Associated diverse activities include:

Develop protection plans that identify critical objectives based on planning requirements, provide a complete and integrated picture of the sequence and scope of the tasks to achieve the planning objectives, and implement planning requirements within the time frame contemplated within the plan using available resources for protection-related plans.

Implement, exercise, and maintain plans to ensure continuity of operations.

Protection Mission Area Core Capabilities is met by the demonstration of REP Program criterion:

I.a.I, 1.c.l, 3.a.l, 3.b.l, 3.c.2, Sa.I, and S.b.1. Mitigation Mission Area Core Capabilities focus on the premise that individuals, the private and nonprofit sectors, communities, and the Nation as a whole are made more resilient when the consequences and impacts, the duration and human cost to respond to and recover all adverse incidents are reduced. Associated diverse activities include:

Build and sustain resilient systems, communities, and critical infrastructure and key resources lifelines so as to reduce their vulnerability to natural, technological, and human-caused threats and hazards by lessening the likelihood, severity, .and du.ration of the adverse consequences.

Assess risk and disaster resilience so that decision makers and responders can take informed action to reduce their entity's risk and increase their resilience.

Mitigation Mission Area Core Capabilities is met by the demonstration of REP Program criterion:

l.d.l, Le.I, 3.d.1, 3;d.2, 4.a.2, 4.a.3, Sa.I, and S.b.l. Response Mission Area Core Capabilities emphasizes saving and sustaining lives, stabilizing the lS Unclassified After Action Report/Improvement Plan Radiological Emergency Preparedness Program (REP) Diablo Canyon Power Plant incident, rapidly meeting basic human needs, establishing a safe and secure environment, and supporting the transition to recovery.

Associated diverse activities include:

Mobilize all critical resources and establish command, control, and coordination structures within the affected community and other coordinating bodies in surrounding communities and across the Nation.

Enhance and maintain command, control and coordination structures, consistent with the National Incident Management System.

Establish physical access through appropriate transportation corridors and deliver required resources to save lives and to meet the needs of disaster survivors.

Identify, assess, and mitigate worker health and safety hazards and disseminate health and safety guidance and resources to response and recovery workers.

Deliver medical countermeasures to exposed populations.

Response Mission Area Core Capabilities is met by the demonstration of REP Program criteria:

La.I, Le.I, Le.I, 2.a.l, 2.b.1, 2.b.2, 2.c.l, 3.a.l, 3.b.l, 3.d.1, 3.d.2, 5.a.l, and 5.b.L 2.3 Scenario and Extent-of-Play Agreement Summary The November 2, 2016, PPX was based on a scenario of events occurring at DCPP that will invoke emergency response actions to be carried out by the OROs. A technical review of the scenario was completed on October 21, 2016, by FEMA, and indicated that it was adequate to support demonstration of DHS/FEMA requirements, as well as selected site evaluation criteria per the EOP agreement and as provided in the REP Program Manual, (January 2016). A summary of the DCPP PPX scenario is as follows: (Times listed below were for planning purposes only.) Initial conditions at DCPP have both units at 100% power and operating at normal operating temperature and pressure.

0809: Containment fan cooling unit, CFCU 1-4, develops a large leak. DCPP operators isolate the leak and electrically disable CFCU 1-4. 16 Unclassified After Action Report/Improvement Plan Radiological Emergency Preparedness Program (REP) Diablo Canyon Power Plant 0833: Significant mechanical damage to a limited number of fuel pins is caused by loose part. Loose parts finally lodging in upper area of fuel assembly, and Unit 1 shutdown initiated per operating procedure.

0929: Centrifugal charging pump, CCP 1-3, experiences an overcurrent condition, but breaker 52-HG-11 fails to open. Auxiliary transformer 1-2 4kV Bus G feeder breaker 52-HG-13 opens, and 4kV Bus G is de-energized and locked out. 1002: Unit 1 main turbine auto-stop oil pressure rapidly decreases when an oil line threaded fitting fails causing a main turbine to "trip" and initiate a reactor trip signal. The reactor fails to trip, and additional fuel damage occurs. The rector is successfully tripped, from Control Room 90 seconds later. 103 7: A loss of coolant accident occurs causing Containment Area High Range Radiation Monitors RM-30/31 to indicate rising radiation levels in containment.

Containment Exhaust Isolation Value RCV-11 disk mechanically fails and rotates slightly off its seat due to manufacturing defect. 1047: Containment High Radiation Monitors RM-30/31 read> 80 R/hr. This constitutes a potential loss of the containment fission product barrier. (PAR to Evacuate Protective Action Zone (PAZ) 1 & 2, & surrounding Ocean out to 5 Nautical Miles) 1126 :_Containment loss and radiological release due to containment exhaust isolation value RCV-12 also rotates off its seat due to common-mode failure as RCV-11, initiating an Off-site radiological release. Radiological release is monitored by plant vent effluent monitors. (PAR Upgrade to Evacuate PAZ 3) 1326: Radiological release is terminated by repairing and closing mechanical damper MD-35, downstream in the effluent pathway. 1330: ENDEX -Approximate time set for exercise termination.

Extent-of-Play Agreement Summary: The purpose of the EOP agreement is to identify, and negotiate, demonstration criteria and any 17 Unclassified After Action Report/hnprovement Plan Radiological Emergency Preparedness Program (REP) Diablo Canyon Power Plant planned deviations from the implementation of the applicable plans that will be evaluated during the exercise.

Applicable plans include the state of California NPP Emergency Response Plan, the California Department of Public Health (DPH) NPP Emergency Response Procedures (also contained within the State NPP Plan), and San Luis Obispo County NPP Emergency Response Plans and Procedures.

The State and OROs will implement applicable elements in these plans and procedures.

The expected outcome of the OR Os is that they demonstrate reasonable assurance that the public can be protected during a NPP incident.

The expected outcome of State participation, in the exercise, is to support OROs in their effort for them to demonstrate reasonable assurance that the public can be protected during a NPP incident.

Pursuant to FEMA policy, federal agencies are not evaluated during an evaluated exercises or drill. Federal actions that result in State or ORO non-compliance of an evaluation area may be documented by the evaluator but will not result in any finding. The FEMA Lead Evaluator and the State Lead ORO Exercise Controller will terminate the exercise when all parties agree that all the required demonstration criteria have been adequately demonstrated and evaluated.
