What is EPLAN Purpose?
- Describe organization
- Classify emergencies per severity
- Defines/Assigns responsibilities
- Outlines course of actions
- Presents post-emergency plans, restore normal
- Defines methods/process to inform public
Which facility serves as the point of origin for the Environmental Teams and Repair Teams?
OSC
Which facility is responsible for providing Protective Action Recommendations?
EOF
At onset of incident, the EC has what NON-DELEGABLE responsibilities?
- Notify Offsite Response and Emergency Orgs (EOD relief later)
- Provide PAR’s (EOD relief later)
- Reclassify events
- Determine need for site evac
- Activate ERO for Alert or Higher
How is transfer of EPLAN command and control accomplished? And what duties?
Form EP-0240
EC-TSC = Classifications, Exposure controls, KI EC-EOF = PAR's, Notifications
When would the EC or EOD authorize deviation from the Safety Manual and related Safety procedures?
- Extreme Circumstances
- Maintain/Restore Core Cooling
- Mitigate Off-Site release in progress
- Fuel damage is imminent
- EPLAN is ALERT or higher classification
Who is responsible for dispatch and tracking of Emergency Teams? And what actions are URGENT?
The EC has responsibility
- Firefighting, Search and Rescue, Lifesaving
- Bomb Search
- HAZMAT (Urgent to High)
The EC controls AO access into plant areas, but what does he NOT direct for AO’s?
Plant Manipulations
- The OSC gives AO direction (on-shift AO’s are directed from CR)
If the SM is physically unable to fulfill EPLAN requirements, what is done both when a transient is IN PROGRESS and NOT IN PROGRESS?
NOT = CRS is responsible for EPLAN
IN PROGRESS = CRS is responsible to assign an EC qualified individual (other units SM’s, etc)
If it is suspected that multiple units may meet or exceed an EAL prior to initial classification, who is designated as On-Shift EC?
U1 Shift Manager
Describe UNUSUAL EVENT
- Potential Degradation of Safety
- Indicate Security threat
- No release requiring off-site expected
- Activates ON-SHIFT ERO
- Notify NRC, State, County
Describe ALERT
- Actual or Potential substantial Degradation
- Threat due to Hostile Action
- Release are expected to be Limited
- Activate All ERO
- Prompt follow up to off-site authorities
Describe Site Area Emergency
- Major Failures of plant functions
- Hostile Action (intentional damage/malicious)
- Releases shouldn’t exceed EPA PAG beyond site
- Activate ALL ERO
- Assembly/Accountability of ONSITE
- ONSITE non-essential must be evacuated on SAE
Describe General Emergency
- Actual or Imminent Core Degradation/Melt
- Potential Loss of CTMT integrity
- Hostile Action (loss of facility control)
- Releases will exceed EPA PAG off-site
- Prompt NRC, State, County notification
- ONSITE EVAC required
- State of AZ response, evacuate public
* PAR consideration now at GE only level
What can indicate an EAL classification?
- Instrument reading
- Equipment Status Indicator
- Measurable Parameter
- Discrete, Observable Event (or phenomenon)
What are the EAL Recognition Categories?
R = Radiological F = Fission Product Barrier S = System Malfunction H = Hazard E = ISFSI C = Cold
When would we enter the EP-0901 Classification?
Any situation where an EAL may have been exceeded or when a classification change may be necessary for an emergency event already in progress
When multiple simultaneous events occur, which classification is used?
The highest EAL reached
- If 2 events in same category, use more specific
If we “Miss” a classification, what do we do?
- Event is reported to NRC within 1 Hour of discovery of undeclared event/condition (per 10CFR50.72)
- Also notify State/Local per agreements
If an EAL is briefly met during an expected (normal) plant response, do we make an emergency declaration?
Or do we declare when an EAL is Momentarily met but corrected by an operator?
NO in both cases (if we hadn’t declared before correction by Operator in case 2)
Per EP-0903, how do we determine if abnormal Radioactive Release is “In-Progress”?
- Effluent monitor readings 3X Normal/Expected
- SGTR with steam release to atmosphere
- Airborne activity found via survey
- Effluent grab samples > Expected
- > ALERT alarm on RU-148/149
A radioactive release in excess of Federally approved limits is indicated when?
- High alarm on any effluent monitor
- Dose projection/sample > .05 mrem/hr TEDE at Site boundary
- Radiation survey ? .05 mrem/hr DDE at Site Boundary
- Grab samples > ODCM Section 3 Limits
When do we make Protective Action Recommendations (PARS)?
When offsite doses are expected to exceed Protective Action Guides (PAG’s)
- Based on Emergency Classification, Status of Fission Product Barriers, and offsite doses
Why do we issue Potassium Iodide?
Reduce potential Thyroid Doses
