SUMMARY

On September 26, 2017, a Radiological Emergency Preparedness Partial-Participation Plume Exposure Pathway Exercise was evaluated by the U.S. Department of Homeland Security/Federal Emergency Management Agency (DHS/FEMA) for the 10-mile Emergency Planning Zone (EPZ) around the Byron Station. The purpose of this exercise was to assess the capabilities of the State and local preparedness organizations in responding to a*radiological emergency. This exercise was held in accordance with the DHS/FEMA policies and guidance concerning the exercise of State and local Radiological Emergency Response Plans (RERPs) and procedures.

The previous exercise at this site was conducted on May 20, 2015. The qualifying emergency preparedness exercise was conducted on November 15, 1983.

  • The DHS/FEMA wishes to acknowledge the efforts of the many individuals who participated in this exercise. Ogle County and Winnebago County participated along with the State of Illinois Emergency Management Agency.

Protecting the public health and safety is the full-time job of some of the exercise participants and an additional assigned responsibility for others. Still others have willingly sought this responsibility by volunteering to provide vital emergency services to their communities.

Cooperation and teamwork on the part of all the participants were evident during this exercise.

This Final After Action Report/Improvement Plan contains the evaluation of the biennial exercise and the evaluation of the following out-of-sequence interviews arid activities:

Jefferson High School Evacuee Registration and Congregate Care interview Protective Actions for Schools interview for Meridian Community Unit School District

Unclassified Radiological Emergency Preparedness (REP) Program After Action Report/Improvement Plan Byron Station SECTION 1: INTRODUCTION 1.1 Exercise Basis On December 7, 1979, the President directed FEMA to assume the lead responsibility for all offsite nuclear planning and response. The DHS/FEMA activities are conducted pursuant to Title 44 of the Code of Federal Regulations (CFR) Parts 350 "Review and Approval of State and Local Radiological Emergency Plans and Preparedness," 351 "Radiological Emergency Planning and Preparedness" and 352 "Commercial Nuclear Power Plants: Emergency Preparedness Planning". These regulations are a key element in the Radiological Emergency Preparedness (REP) Program that was established following the Three Mile Island Nuclear Station accident in March 1979.

FEMA Regulation 44 CFR 350 establishes the policies and procedures for the DHS/FEMA initial and continued approval of State and local governments' radiological emergency planning and preparedness for commercial nuclear power plants. This approval is contingent, in part, on State and local governments' participation in joint exercises with licensee.

The DHS/FEMA responsibilities in radiological emergency planning for fixed nuclear facilities include the following:

Taking the lead in offsite emergency planning and in the review and evaluation of Radiological Emergency Response Plan and procedures developed by State and local governments; Determining whether such plans and procedures can be implemented on the basis of observation and evaluation of exercises of the plans and procedures conducted by State and local governments; Responding to requests by the U.S. Nuclear Regulatory Commission pursuant to the Memorandum of Understanding between the NRC and FEMA dated October 1, 2015, and; Coordinating the activities of Federal agencies with responsibilities in the radiological emergency planning process:

U.S. Department of Agriculture; U.S. Department of Commerce; U.S. Department of Energy; U.S. Department of Health and Human Services; U.S. Department of the Interior; U.S. Department of Transportation; U.S. Environmental Protection Agency; U.S. Food and Drug Administration; and U.S. Nuclear Regulatory Commission.

Unclassified Radiological Emergency Preparedness (REP) Program After Action Report/Improvement Plan Byron Station Representatives from these agencies serve on the DHS/FEMA Region V Regional Assistance Committee (RAC), which is chaired by the DHS/FEMA.

Formal submission of the RERP for Byron Station to FEMA Region V by the State of Illinois and involved local jurisdictions occurred on March 28, 1982. Formal approval of these RERP was granted by FEMA on September 12, 1984, under 44 CFR 350.

A Radiological Emergency Preparedness (REP) Partial-Participation Plume Exposure Pathway Exercise was conducted on September 26, 2017, and evaluated by the DHS/FEMA to assess the capabilities of State and local offsite emergency preparedness organizations in implementing their RERPs and procedures to protect the public health and safety during a radiological emergency involving the Byron Station. The purpose of this AAR/IP is to present the exercise results and findings based on the performance of the off site response organizations during a simulated radiological emergency.

The findings presented in this Final After Action Report/Improvement Plan are based on the evaluations of the federal evaluation team, with final determinations made by the DHS/FEMA Region V RAC Chair, and approved by the DHS/FEMA Headquarters.

The criteria utilized in the FEMA evaluation process are contained in:

NUREG-0654/FEMA.:-REP-1, Rev. 1, "Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants," November 1980; FEMA Radiological Emergency Preparedness: Exercise Evaluation Methodology, as published in the FEMA Radiological Emergency Preparedness Manual, dated January 2016.

The exercise was conducted to test the offsite emergency response capabilities of State and local governments in the I 0-mile Emergency Planning Zone (EPZ) surrounding the Byron Station.

Each jurisdiction and functional entity was evaluated based on its demonstration of exercise criteria delineated in the FEMA REP Program Manual, dated January, 2016. Appendix E, Extent-of-Play, contains detailed information on the selected exercise criteria and the extent-of-play agreements used for this exercise. Presented below are definitions of the terms used in this report relative to the criteria demonstration status.

M - Met: The status of a REP exercise evaluation area criterion indicating that the participating OROs demonstrated all demonstration criteria for the evaluation area criterion to the level required in the extent-of-play agreement with no Level I Findings, Level 2 Findings or Plan Issues assessed in the current exercise and no unresolved prior Level 2 Findings.

1 - Level I Finding: An observed or identified inadequacy of organizational performance in an exercise that could cause a finding that offsite emergency preparedness is not adequate to provide reasonable assurance that appropriate protective measures can be taken in the event of a radiological emergency to protect the health and safety of the public living in the vicinity of a nuclear power plant.

2 - Level 2 Finding - An observed or identified inadequacy of organizational performance in an exercise that is not considered, by itself, to adversely impact public health and safety.

P -Plan Issue -An observed or identified inadequacy in the ORO's emergency plan or implementing procedures, rather than in the ORO's performance.

N - Not Demonstrated - Exercise criteria that were not demonstrated as scheduled during this exercise and the reason( s) they were not demonstrated.

Unclassified Radiological Emergency Preparedness (REP) Program After Action Report/Improvement Plan NARRATIVE

SUMMARY

Initial Conditions - 0755 CDT

  • Byron Station The Operating Crew will be briefed at 0700 and is expected to take the shift by 0755.

The crew will be directed to continue full power on Unit 1 and Unit 2. There is electrical bus work in progress on the 2B River Screen House Transformer, and therefore Bus 045-01 is cross tied to Bus 045-02. The OC Service Water Pump is undergoing an impeller replacement, and is in day 10 of 20 of the work window. Finally, the 2A Diesel Generator has an Operability Surveillance (2BOSR 8.1.2-1) that is scheduled to start at 0900 today.

ALERT-0810 At 0800 the National Weather Service will issue a Severe Thunderstorm WARNING for Ogle County that is in effect until 0830. The WEC (Work Execution Center) Supervisor has a weather radio that he listens to, and will call the Control Room Simulator with this information. The crew will respond by entering 0(1)(2)BOA ENV-1, and will contact all out buildings to inform them of the storm along with delaying the 2A DG Surveillance.

The wind speed will climb from 0800 to 0810 to -55mph at its peak. At 0810 multiple pieces of debris from a truck carrying lumber on German Church Road (which runs N-S along the side of the plant) will impact the OA SX Cooling tower causing the OA/OB/OC

  • fans to trip due to the damage. The Security Guard in the BRE (Bullet Resistant Enclosure) will report the visible damage to the Control Room. The crew will respond per BAR 0-37-B6 and lBOA PRI-7 which requires an EO be dispatched to investigate the cause of the trip. The dispatch of an EO may be delayed due to safety concerns from the high winds.

The Shift Manager will declare an ALERT (MA5) due to high winds causing visible damage to a Safety System required by Tech Specs for the current operating mode. The ERO will be activated via PA and Everbridge notifications. Command and Control will be transferred to the EOF and TSC when the facilities are activated. Notifications to the State will be made via the NARS system from the Control Room Simulator.

At 0825 the A Circ Water Pump will trip due to high differential pressure across the A Traveling Screen from debris in the intake. The crew will respond per BAR 0-38-A-l l and OBOA SEC-11. This again requires dispatching an EO to investigate, but it may be delayed due to the safety concerns from the high winds. The crew will be able to successfully start the B Circ Water Pump if attempted.

Between 0825 and 0840 the wind speed will reside back to -25mph where it will stay for the remainder of the scenario. When wind speed comes back down, the crew should dispatch operators in accordance with the procedures if not already done.

Equipment Malfunctions 64

Unclassified Radiological Emergency Preparedness (REP) Program After Action Report/Improvement Plan Byron Station The following set of casualties will be tracked, evaluated, and prioritized by the ERO.

Some, if not all, of the response actions will come from the OSC after command and control is turned over to the TSC and EOF.

At 0830 the IB Feed Pump will trip and develop a steam leak from the Turbine Stop Valve. The crew will respond per BHC 1-16-BCI and start the IA Feed Pump (motor driven). Operators will be dispatched to isolate the steam leak but will find the handwheel on the 1MS-072A is free spinning due to a broken key. MM's will be required to be dispatched to assist in closing the valve.

At 0850 a Rod Control Urgent Failure alarm will come in and the crew will respond per IBOA ROD-2. The IM's, when dispatched, will discover a loose card in the IBD Rod Control Cabinet. This can be fixed.

At 0855 the CC Surge Tank level transmitter (1LT676) will fail low causing an alarm to come in and makeup to the CC Surge Tank to automatically start. The crew will respond per IBOA PRI-6 and attempt to isolate the WM makeup source via 1CC183 from the control room but will be unsuccessful. When EO's are dispatched to locally isolate the makeup they will find the tank overflowing to the Floor Drain System. The first isolation valve (1 CC 185) will have a 90° operating handle free moving. The second isolation valve (1 CC9454A) will have an EST (Equipment Status Tag) on the handwheel stating that the valve is mechanically bound in the open position. MM' s will be required to be dispatched to assist in closing the 1CC185 valve.

At 0900 the IA SX Pump will trip due to an overcurrent condition. The crew will respond per BHC 12-Al and IBOA PRI-7 and start the IB SX Pump. When EM's are dispatched to look at the breaker they will find char marks around the Control Power fuse and an acrid odor. There are no indications of flame or smoke.

SITE AREA EMERGENCY - 0920 CDT At 0910 the D RCS Loop will develop a significant LOCA (Loss of Coolant Accident) of

-IOOOgpm.

The crew will respond by tripping the reactor and manually actuating Safety Injection.

Phase A Isolation actions will not automatically actuate for the B Train, and the Control Room operators will have to manually align the equipment. This condition constitutes a concurrent ALERT (FAI) due to a Loss of the RCS (RC.I). The transient incurred from the LOCA will cause localized spots in the core to exceed temperature limits and fuel damage will occur. This will be evident by Containment radiation level rising significantly.

The IA Aux Feed Pump will start, but will experience a broken motor shaft preventing flow from being developed. When a team is dispatched they will find sparks emanating 65

Unclassified Radiological Emergency Preparedness (REP) Program After Action Report/Improvement Plan Byron Station from around the shaft and a loud grinding noise. The crew will trip the IA Aux Feed Pump.

At 0920 the Containment radiation level will exceed 1950R/hr and peak at 2250R/hr.

The Station Emergency Director will classify a SITE AREA EMERGENCY (FSl) due to the Loss of the RCS and Loss of the Fuel Clad, and the EOF will notify the State via the NARS system. Additionally, a station assembly will be enacted by the TSC (this will be a real assembly, not simulated).

GENERAL EMERGENCY - 1030 CDT Containment pressure will rise due to the LOCA with a peak of around -1 Opsig. If the crew were to attempt to start the IA Containment Spray (lB is out of service) to combat the rising Containment pressure, an overcurrent condition will be experienced on the IA CS Pump. At 1010 the ID RCFC (Reactor Containment Fan Cooler) will trip due to an overcurrent condition. When a team is dispatched they will find the breaker in a tripped position, and will be able to reset the breaker to restart the ID RCFC.

At 1030 the Containment Penetration P95 will fail causing a rapid drop in Containment pressure and a release into the 451' Aux Building elevation. After the initial Containment pressure drop, it will trend to 3 psig over the remainder of the scenario. A radioactive release in progress will commence as the Unit 1 and Unit 2. Aux Building Vent Stack monitors rise initially to 5.0E+04 uCi/sec. The release will be from URJ Path H ( <RCS><Containment><Aux Building><Filters><Stack><Environment>) and will rise to a peak of 6.0E+07 uCi/sec at 1100.

The Station Emergency Director will classify a GENERAL EMERGENCY (FGl) due to Loss of Fuel Clad, Loss of RCS, and Loss of Containment. The EOF will develop PARs to Evacuate IL Sub-areas 19, 23, 25 and will notify the State via the NARS system.

Field Monitoring Teams will be sent to strategic locations downwind (from 290) to track the plume. Dose Assessments will not yield any areas exceeding Protective Action Guidelines.

The Ops crew will enter cooldown (lBEP ESl.2) and could use S/G PORVs as an option for cooldown. There is no leakage between the primary and secondary systems, so this will not add to the radioactive release.

Exercise Termination - -1230 CDT The exercise will be terminated after all participating facilities have demonstrated their objectives sufficiently. After termination, all facilities will conduct a critique of their performance.
