98-06 5.1 INITIAL CONDITIONS The exercise date is assumed to be Wednesday, October 28,1998. The plant has been shutdown since December of 1996, the fuel has been removed from the reactor vessel and is stored in the Spent Fuel Pool.

Decommissioning activities are progressing in accordance with the integrated schedule. The SFP Diesel is scheduled for routine load testing later this moming.

Radiation Protection Staff are preparing a HIC for transport from the Low Level Waste Storage Building. This should be completed by 1130 this moming.

All required equipment and systems are functioning or is available if needed.

Radiation Protection Staff are preparing a HIC containing radioactive filter media for transport to the Low Level l I

Waste Storage Building from the Fuel Building area. This should be completed by 1130 this moming.

All required equipment and systems are functioning or is available if needad.

l At approximately 0902, Security reports to the Control Room that they physically felt the ground shake and noticed the asphait outside of the Admin. Building has fractured and separated in several places.

Simultaneously several log books and manuals were noted to fall out of bookshelves in the Security Office.

Shortly after, the CMP dispatcher informs the Shift Manager (SM) that the National Weather Service has issued reports of an earthquake registering a five on the Richter Scale, initial indications are that the quake was centered off the coast of Maine, east of Acadia National Park, l

Shift personnelinitiate a walkdown in accordance with AOP-2-41 to determine if there has been any impact l I

on site. Up to this point, no alarms have been received in the Control Room regarding this event. Initial reports from site personnel result in the SM declaring an Unusual Event in accordance with Procedure l 2-50-0, Emergency Classification, Notification and ERO Activation, Event 2.2 - Natural and Destructive (

Phenomena Affecting the Site. l At approximately 0940, an after shock is felt which causes damage to the Spent Fuel Pool Cooling electrical circuits and results in the HIC being toppled off of the flat car outside of the Fuel Building Building. The contents of the HIC (filters) spill onto the ground, resulting in general area dose rates of approximately 7000 mrem /hr on contact and 800 mrem /hr at 1 meter.

l Operations staff continue to perform a walkdown of the plant, an isolated case of damage to the Spent Fuel Pool Building structural support is identified, the Spent Fuel Pool Cooling / Decay Heat Removal Fans' electrical circuits have been damaged and all fans have stopped operating. This is indicated on the PLC in the Control Room and the fan noise level decreases dramatically outside the SFP Building. These conditions satisfy the i criteria for an ALERT in accordance with Procedure 2-50-0, Emergency Classification, Notification and ERO Activation, Event 2.2 - Natural and Destructive Phenomena Affecting the Controlled Access Area and Spent Fuel Building Integrity.

l The Emergency Response Organization (ERO) should be activating and staffing the Technical Support Center (TSC). Based on initial evaluation of the situation, TSC Coordinators should determine the appropriate i support staff to mitigate the situation and provide support to the Control Room. l l

In order to ensure continued cooling to the SFP, the SM may request supplemental / emergency cooling of the SFP be evaluated / implemented by the TSC. In addition, Damage Control personnel should be dispatched to determine the extent of damage to the SFP Cooling system and propose a repair strategy.

The Radiological Assessment Staff should request general area and airbome surveys around the toppled HIC, the survey results should be assessed to determine potential Site Boundary dose rates. In addition, RP Sta'f

MAINE YANKEE Page 5.2-2 EMERGENCY PREPAREDNESS EXERCISE 9/1/98 98-06 should be directed to ascertain the extent of measurable radiation from the event and coordinate efforts to minimize exposure to repair teams in the area of the SFP DHR fans or those responsible for restoring cooling to the Spent Fuel Pool.

The Technical Response Staff should evaluate the structural integrity of the Fuel Building based on information provided by 60 servers and Damage Control Response personnel.

The exercise will progress based on the pnoritized repair efforts to restore SFP cooling (either via emergency cooling methods or repairs to the electrical circuit) and containing/up righting the toppled HIC.

The exercise may be terminated under the following circumstances:

a. When all emergency response actions have been completed in accordance with the exercise time sequence and objectives to be demonstrated have been addressed ; or
b. An actual plant emergency condition develops coincident with the exercise.

The Exercise Coordinator will take appropriate actions to coordinate exercise termination.

6.0 Succortino information l

This section contains information required to initiate the exercise activities and to direct the response l l along a preplanned event sequence. Information will be provided to the responders in the form of message cards. Message cards can contain information to be interpreted by the responder in order to take a response action, they may direct certain actions be taken and if in the judgement of the controller a desired action is not imminent. Plant parameters will also be made available on a periodica basis to allow responders to interpret the similated plant condition and make appropriate adjustments accordingly. Message and Command Cards have location designators based on where the card is to be issued (i.e. CR - Control Room, TSC- Technical Support Center, DCT#X- Damage i Control Team #X, RP- Radiation Protection, etc.)

Section 6.1 contains Message Cards. Message cards describe conditions being simulated, based on the scenario.

Section 6.2 contains Command Cards. Commands which direct a responder to take an action.

Section 6.3 contains Data Cards. Plant parameters reflecting the progress of the scenario relative to the predetermined time scale. All Data Cards will be made available to the ERO staff member at the Programmable Logic Controller terminal (PLC).

We felt the ground shake and then the HIC fell off of the flat bed trailer. The contents of the HIC, exposed filter media, have spilled onto the ground outside the rollup door to the building. Inital rad levels are as follows:

HIC contact reading 7000 mr/hr 1 meter from HIC = 800 mr/hr.

There is some contamination on the ground, we're in the process of taking a swipe.

No injuries are apparent and the extent of the situation is being assessed by available staff.

MAINE YANKEE Page 6.1-7 EMERGENCY PREPAREDNESS EXERCISE 9/1/98 98-06 THIS IS A DRILL TSC-M-1 To be provided to the Emergency Director upon arrival in the TSC Initial Conditions (at the start of the exercise) were as follows:

The exercise date is assumed to be Wednesday, October 28,1998. The plant has been shutdown since December of 1996, the fuel has been removed from the reactor vessel and is stored in the Spent Fuel Pool.

Decommissioning activities are progressing in accordance with the integrated schedule. The SFP Diesel is scheduled for routine load testing later this moming.

Radiation Protection Staff have been preparing a HIC for transport to the Low Level Waste Storage Building from the Fuel Building. This should be completed by 1130 this moming.
