- Forwarded to Emergency Preparedness within seven (7) working days of approval.Symptoms 1.1 This procedure describes the immediate actions to be taken to recognize and classify an emergency condition.
1.2 This procedure identifies the four emergency classifications and their corresponding Emergency Action Levels (EALs).1.3 This procedure provides reporting requirements for non-emergency abnormal events.1.4 The following guidance is to be used by the Emergency Coordinator/EOF Director in assessing emergency conditions:
1.4.1 Definitions
and Acronyms are italicized throughout procedure for easy recognition.
The definitions are in Enclosure 4.10 (Definitions/Acronyms).
1.4.2 The Emergency Coordinator/EOF Director shall review all applicable initiating events to ensure proper classification.
1.4.3 The BASIS Document (Volume A, Section D of the Emergency Plan) is available for review if any questions arise over proper classification.
1.4.4 IF An event occurs on more than one unit concurrently, THEN The event with the higher classification will be classified on the Emergency Notification Form.A. Information relating to the problem(s) on the other unit(s) will be captured on the Emergency Notification Form as shown in RP/0/A/ 1000/01 5A, (Offsite Communications From The Control Room), RP/0/A/1000/015B, (Offsite Communications From The Technical Support Center) or SR/O/A/2000/004, (Notification to States and Counties from the Emergency Operations Facility).
2 RP/O/A/ 1000/001 Page 3 of 6 1.4.5 IF An event occurs, AND A lower or higher plant operating mode is reached before the classification can be made, THEN The classification shall be based on the mode that existed at the time the event occurred.1.4.6 The Fission Product Barrier Matrix is applicable only to those events that occur at Mode 4 (Hot Shutdown) or higher.A. An event that is recognized at Mode 5 (Cold Shutdown) or lower shall not be classified using the Fission Product Barrier Matrix.1. Reference should be made to the additional enclosures that provide Emergency Action Levels for specific events (e.g., Severe Weather, Fire, Security).
1.5 IF A transient event should occur, THEN Review the following guidance: 1.5.1 IF An Emergency Action Level (EAL) identifies a specific duration AND The Emergency Coordinator/EOF Director assessment concludes that the specified duration is exceeded or will be exceeded, (i.e.;condition cannot be reasonably corrected before the duration elapses), THEN Classify the event.1.5.2 IF A plant condition exceeding EAL criteria is corrected before the specified duration time is exceeded, THEN The event is NOT classified by that EAL.A. Review lower severity EALs for possible applicability in these cases.3 RP/O/A/ 1000/001 Page 4 of 6.NOTE: Reporting under 1OCFR50.72 may be required for the following step. Such a condition could occur, for example, if a follow up evaluation of an abnormal condition uncovers evidence that the condition was more severe than earlier believed.i 1.5.3 IF AND THEN A plant condition exceeding EAL criteria is not recognized at the time of occurrence, but is identified well after the condition has occurred (e.g.; as a result of routine log or record review)The condition no longer exists, An emergency shall NOT be declared.* Refer to AD-LS-ALL-0006 (Notification/Reportability Evaluation) for reportability 1.5.4 IF An emergency classification was warranted, but the plant condition has been corrected prior to declaration and notification THEN The Emergency Coordinator must consider the potential that the initiating condition (e.g.; Failure of Reactor Protection System) may have caused plant damage that warrants augmenting the on shift personnel through activation of the Emergency Response Organization.
A. IF An Unusual Event condition exists, THEN Make the classification as required.1. The event may be terminated in the same notification or as a separate termination notification.
B. IF An Aler4 Site Area Emergency, or General Emergency condition exists, THEN Make the classification as required, AND Activate the Emergency Response Organization.
1.6 Emergency
conditions shall be classified as soon as the Emergency Coordinator/EOF Director assessment determines that the Emergency Action Levels for the Initiating Condition have been exceeded.4 RP/O/A/1000/001 Page 5 of 6 2. Immediate Actions 2.1 Assessment, classification and declaration of any applicable emergency condition should be completed within 15 minutes after the availability of indications or information to cognizant facility staff that an EAL threshold has been exceeded.2.2 Determine the operating mode that existed at the time the event occurred prior to any protection system or operator action initiated in response to the event.2.3 IF The unit is at Mode 4 (Hot Shutdown) or higher AND The condition/event affects fission product barriers, THEN GO TO Enclosure 4.1, (Fission Product Barrier Matrix).2.3.1 Review the criteria listed in Enclosure 4.1, (Fission Product Barrier Matrix)and make the determination if the event should be classified).
2.4 Review
the listing of enclosures to determine if the event is applicable to one of the categories shown.2.4.1 IF One or more categories are applicable to the event, THEN Refer to the associated enclosures.
2.4.2 Review
the EALs and determine if the event should be classified.
A. IF An EAL is applicable to the event, THEN Classify the event as required.2.5 IF The condition requires an emergency classification, THEN Initiate the following:
- for Control Room -RP/O/A/1000/002, (Control Room Emergency Coordinator Procedure) o for TSC -RP/O/A/1000/0 19, (Technical Support Center Emergency Coordinator Procedure)" for EOF -SR/O/A/2000/003, (Activation of the Emergency Operations Facility)2.6 Continue to review the emergency conditions to assure the current classification continues to be applicable.

List of Definitions and Acronyms NOTE: Definitions are italicized throughout procedure for easy recognition.
1.1 ALERT
-Events are in process or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant or a security event that involves probable life threatening risk to site personnel or damage to site equipment because of HOSTILE ACTION. Any releases are expected to be limited to small fractions of the EPA Protective Action Guideline exposure levels.1.2 BOMB -Refers to an explosive device suspected of having sufficient force to damage plant systems or structures.
1.3 COGNIZANT
FACILITY STAFF -any member of facility staff, who by virtue of training and experience, is qualified to assess the indications or reports for validity and to compare the same to the EALs in the licensee's emergency classification scheme. (Does not include staff whose positions require they report, rather than assess, abnormal conditions to the facility.)
1.4 CONDITION
A -Failure is Imminent or Has Occurred -A failure at the dam has occurred or is about to occur and minutes to days may be allowed to respond dependent upon the proximity to the dam.@ 1.5 CONDITION B -Potentially Hazardous Situation is Developing
-A situation where failure may develop, but preplanned actions taken during certain events (such as major floods, earthquakes, evidence of piping) may prevent or mitigate failure.1.6 CIVIL DISTURBANCE
-A group of persons violently protesting station operations or activities at the site.1.7 EXPLOSION
-A rapid, violent, unconfined combustion, or catastrophic failure of pressurized/energized equipment that imparts energy of sufficient force to potentially damage permanent structures, systems, or components.
1.7 EXTORTION
-An attempt to cause an action at the station by threat of force.1.8 FIRE -Combustion characterized by heat and light. Sources of smoke, such as slipping drive belts or overheated electrical equipment, do NOT constitute fires. Observation of flames is preferred but is NOT required if large quantities of smoke and heat are observed.1.9 FRESHLY OFF-LOADED CORE -The complete removal and relocation of all fuel assemblies from the reactor core and placed in the spent fuel pool. (Typical of a "No Mode" operation during a refuel outage that allows safety system maintenance to occur and results in maximum decay heat load in the spent fuel pool system).22 Enclosure 4.10 RP/O/A/1000/001 Definitions/Acronyms Page 2 of 5 1.10 GENERAL EMERGENCY
-Events are in process or have occurred which involve actual or imminent substantial core degradation or melting with potential for loss of containment integrity or HOSTILE ACTION that results in an actual loss of physical control of the facility.Releases can be reasonably expected to exceed EPA Protective Action Guidelines exposure levels offsite for more than the immediate area.1.11 HOSTAGE -A person(s) held as leverage against the station to ensure demands will be met by the station.1.12 HOSTILE ACTION -An act toward an NPP or its personnel that includes the use of violent force to destroy equipment, takes HOSTAGES, and/or intimidates the licensee to achieve an end.

Instructions For Using Enclosure 4.1 -Fission Product Barrier Matrix 1.1 If the unit was at Hot S/D or above, (Modes 1, 2, 3, or 4) and one or more fission product barriers have been affected, refer to Enclosure 4.1, (Fission Product Barrier Matrix) and review the criteria listed to determine if the event should be classified.
1.1.1 For each Fission Product Barrier, review the associated EALs to determine if there is a Loss or Potential Loss of that barrier.NOTE: An event with multiple events could occur which would result in the conclusion that exceeding the loss or potential loss thresholds is imminent (i.e. within 1-3 hours). In this situation, use judgement and classify as if the thresholds are exceeded.1.2 Three possible outcomes exist for each barrier. No challenge, potential loss, or loss.Use the worst case for each barrier and the classification table at the bottom of the page to determine appropriate classification.
1.3 The numbers in parentheses out beside the label for each column can be used to assist in determining the classification.
If no EAL is met for a given barrier, that barrier will have 0 points. The points for the columns are as follows: BFmkr Ualm PoQin RCS Potential Loss 4 Loss 5 Fuel Clad Potential Loss 4 Loss 5 Containment Potential Loss 1 Loss 3 1.3.1 To determine the classification, add the highest point value for each barrier to determine a total for all barriers.
Compare this total point value with the numbers in parentheses beside each classification to see which one applies.1.3.2 Finally as a verification of your decision, look below the Emergency Classification you selected.
The loss and/or potential loss EALs selected for each barrier should be described by one of the bullet statements.
28 Enclosure 4.12 Instructions For Using Enclosure 4.1 RP/O/A/1000/001 Page 2 of 2 EXAMPLE: Failure to properly isolate a 'B' MS Line Rupture outside containment, results in extremely severe overcooling.
PTS entry conditions were satisfied.
Stresses on the 'B' S/G resulted in failure of multiple S/G tubes.RCS leakage through the S/G exceeds available makeup capacity as indicated by loss of subcooling margin.Barrier EAL Failure Points RCS SGTR > Makeup capacity of one HPI pump in Potential Loss 4 normal makeup mode with letdown isolated Entry into PTS operating range Potential Loss 4 RCS leak rate > available makeup capacity as Loss 5 indicated by a loss of subcooling Fuel Clad No EALs met and no justification for No 0 classification on judgment I I_ Challenge Containment Failure of secondary side of SG results in a Loss 3 direct opening to the environment RCS 5 + Fuel 0 + Containment 3 = Total 8 A. Even though two Potential Loss EALs and one Loss EAL are met for the RCS barrier, credit is only taken for the worst case (highest point value) EAL, so the points from this barrier equal 5.B. No EAL is satisfied for the Fuel Clad Barrier so the points for this barrier equal 0.C. One Loss EAL is met for the Containment Barrier so the points for this barrier equal 3.D. When the total points are calculated the result is 8, therefore the classification would be a Site Area Emergency.
E. Look in the box below "Site Area Emergency".
You have identified a loss of two barriers.
This agrees with one of the bullet statements.
The classification is correct.29 Enclosure 4.13 RP/O/A/1000/001 References Page 1 of 1 I

Licensing Basis: 1OCFR50.47b (4) A standard emergency classification and action level scheme, the bases of which include facility system and effluent parameters, is in use by the nuclear facility licensee, and State and local response plans call for reliance on information provided by facility licensees for determinations of minimum initial offsite response measures.NUREG 0654II.D.1 An emergency classification and emergency action level scheme as set forth in Appendix I must be established by the licensee.
The specific instruments, parameters or equipment status shall be shown for establishing each emergency class, in the in-plant emergency procedures.
The plan shall identify the parameter values and equipment status for each emergency class.PiS E-Plan Section D, EMERGENCY CLASSIFICATION SYSTEM States;*eg Guide 1.101, Rev. 3, August, 1992, approved the guidance provided by NUMARC/NESP-007, Revision 2, as an Alternative Methodology for the Development of Emergency Action Levels. Oconee Nuclear Site used the NUMARC guidance for the development of initiating conditions and emergency action levels. The emergency action levels provided in this section have been modified to implement the guidance provided in NRC Bulletin 2005-02, NEI guidance as endorsed in Regulatory Issue Summary 2006-12 and to support the implementation of NEI 03-12.Changes to ONS E-Plan Section D, EMERGENCY CLASSIFICATION SYSTEM documented under separate 50.54q evaluation.

HPI Forced cooling represents the failure of the steam generators to remove heat from the core. To use this mode of cooling indicates that all feedwater (both main and emergency) are not available for use and the pressure of the reactor coolant system is greater than or equal to 2300 psig. The power-operated relief valve must be opened to initiate the cooling through the high pressure injection system. In effect, a self-imposed loss of coolant is established.
This condition is classified as a potential loss of the reactor coolant system. HPI Forced Cooling is classified as an Alert from RP/0/A/1000/001 Enc. 4.1 Fission Product Barrier Matrix.,Conclusion:

Conclusion:
BL0C- 5!.Evaluation:
Current wording in Enc. 4.4.S.2.C states: "EOP directs feeding SG from SSF ASWP or PSW Pump. The installation of the PSW Pump enabled the Station to not require a blow-down of the SG's in order to commence feeding to achieve shutdown cooling, as the PSW pump is a high discharge head pump. The installation and use of the PSW pump provides a better margin of safety for the plant. The use of the PSW pump remains consistent with the technical bases of the EAL (NUMARC -NESP-007, IC -SS4 -Complete Loss of Heat Removal Capability EAL 1 Loss of core cooling and heat sink (PWR). Core exit thermocouple readings are considered to be the average of the five (5) highest thermocouple reading shown on the Inadequate Core Cooling Monitor. The SSF can provide the following:
(1) makeup to the Reactor Coolant Pump seals, (2) low pressure service water to the steam generators, (3) capability to keep the unit in hot shutdown for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> following an Appendix R fire. This change is then in keeping true to the basis as currently written.The basis provides, "This EAL addresses complete loss of functions core cooling and heat sink required for hot shut down with the reactor at pressure and temperature.
Under these conditions, there is an actual major failure of a system intended for protection of the public. Thus, declaration of a Site Area Emergency is warranted with the total loss of main and emergency feedwater with SSF and PSW unavailable coincident with degraded High Pressure Injection.
Escalation to General Emergency would be via Abnormal Rad Levels/Radiological Effluent, Emergency Coordinator Judgment or Fission Product Barrier Degradation ICs".Conclusion:
The proposed activity F] does / does not constitute a RIE.ffectiveness Evaluation Results LOCK6 The activity does continue to comply with the requirements of §50.47(b) and §50 Appendix E and the activity does not constitute a reduction in effectiveness.
