LI C-1 5-01 02 Enclosure Page 3 FC-RAI-03 Section 4.6, "Basis Document," to NEt 99-01, Revision 6, states, in part, that: "Because the information in a basis document can affect emergency classification decision-making

.."The NR~C staff expects that changes to the basis document will be evaluated in accordance with the provisions of Title 10 of the Code of Federal Regulations (10 CFR) paragraph 50.54(q), "Emergency plans.*" Please ensure that appropriate information is incorporated as related to how the technical basis doCUment will be maintained in accordance with 10 CFR 50.54(q).  :

FC-RAI-03 Response EP-FC-120 Emergency Plan Administration states:

4.1.3 Implementing Procedures, Administrative Procedures, and EP Documents

1. EP document changes shall be revised and processed per Attachment 2, EP Document Structure and Revision Process.

2. All document changes will receive a §50.54(q) evaluation per EP-F~C-120-1001. states:

2.3 Emergency Plan revision process:

1. Prior to implementation of Emergency Plan revisions PERFORM the following:

A. A §50.54(q) evaluation per EP-FG-120-1001.

FC-RAI-04 Section 4.7, "EAL/Threshold References to AOP (Abnormal Operating Procedure) and EOP [Emergency Operating Procedure] Setpoints/Criteria," to NEI 99-01, Revision 6, states, in part, that: "As reflected in the generic guidance, the criteria/values used in several EALs and fission product barrier thresholds may be drawn from a plant's AOPs and EOPs," The NRC staff expects that changes to AOPs and EOPs will be evaluated in accordance with the provisions of 10 CFR 50.54(q). Please ensure that verify that appropriate information is incorporated that ensures changes to AOPs or EOPs are screened to determine if an evaluation pursuant to 10 CFR 50.54(q) is required, FC-RAIo04 Response All EOP/AOP changes are required to be verified by the EOPIAOP Coordinator using the Verification Review Checklist (SO-G-74, Attachment 1). The checklist asks the following question: Is EOP/AOP change free of modifications, additions and deletions of any conditions in an emergency action level (EAL) indicator or basis? "No" response requires 50.54(q) evaluation by Emergency Preparedness. AOP-O1 Acts of Nature and AOP.07 Evacuation of Control Room are required to have Emergency Preparedness review.

FC-RAI-05 Section 4.6, "Basis Document," to NEI 99-01, Revision 6, states, in part, that: "A basis document is an integral part of an emergency classification scheme.

Page 4 classification, if necessary.' Emergency Planning implementing Procedure EPIP-OSC-1, "Emergency Classification," was provided for the NRC staff's review as part of the previous NEI 99-01, Revision 5 conversion request dated August 15, 2008 (ADAMS Accession No. ML082320484). Please provide a similar document that includes the addresses the following information:

• A "Purpose" section that reflects the intent of the EAL Basis Document, as provided in NEI 99-01, Revision 6;

• A site-specific Definition/Acronyms section that provides information consistent with NEI 99-01, Revision 6, Appendices A and B;

• An Operating Mode Applicability section that provides information consistent with NEl 99-01 , Revision 6, Section 3.5;

• An implementation guidance section that provides information consistent with NEt 99-01, Revision 6, Section 5; and

• A copy of the FCS classification aid used to facilitate event classifications, which is typically referred to as a "Wallboard."

FC-RAI-05 Response The above is provided in this response for review as Attachment 1 =Front Matter'~ and as "Procedure Matrix" job aide.

FC-RAI-06 For Initiating Condition (IC) RG1, radiation monitor (RM)-064 was removed from Table RI.

RM-064 is included in the currently approved AG1 EAL (ADAMS Accession No. ML13358A327). A justification for the removal of RM-064 was not provided in Attachment 2, Enclosure 2A, "EAL Comparison Matrix Document." Please provide justification for the removal of RM-064 from the RGI.

FC-RAI-06 Response Upon further review FOS has decided to maintain the RM-064 Post Accident Main Steam (Gas) monitor in the RG1 EAL Scheme.

FC-RAI-07 For IC RS1, Table R1 has monitors RM-063, RM-052, and RM-043 listed. IC AS1, in Revision 2a of TBD-EPIP-OSC-1A dated December 11, 2013 (ADAMS Accession No. ML13358A327), and the Revision 5 conversion request dated August 15, 2008, has RM-064 listed in addition to RM-063, but does not include RM-052 and RM-043. These changes are not identified in the Attachment 2, Enclosure 2A, "EAL Comparison Matrix Document." Please provide justification for the removal of monitor RM-064 and the addition of RM-052 and RM-043 to the EAL.

FC-RAI-07 Response Upon further review FCS has decided to maintain the RM-064 Post Accident Main Steam (Gas) monitor in the RS1 EAL Scheme.

SLIC-15-0102 Enclosure Page 5 The following has been added to the RS1 Comparison Matrix justification column to justify the addition of RM-052 and RM-043 rad monitors to the RSI threshold. *-

• RM-052 and RM-043 were added as they are typical radiological effluent pathway monitors with ranges that c~an detect EAL thresholds at RS1 levels as calculated by site calculation RP-AA-1 010 PC-I15-003 (RA 13-008) Rev. I included in this response as Attachment 3,..

FC-RAI-08 For Its RAl and RUl, the RM-057 value for an Alert classification is 1 .79E+08 counts per minute (cpm), while the RM-057 value for an Unusual Event classification is a higher value of 8.82E+08 cpm. Additionally, a note for IC RU1 Table fl3, "Effluent Monitor Thresholds," provides that "1.45E+-08 [cpm] as the upper range of the instrument." Both of these values are above the upper range of the instrument. Please verify that the provided RM-057 values are within the calibrated range of the instrumentation or revise accordingly.

PC-RAI-08 Response A review and recalculation of thresholds for RM-057 has resolved the issue with instrument overange, the upper indication of the instrument has been verified to be 1.45 E+08 cpm, the revised values are within this upper indication and have been used to update RAl and RU I thresholds with respect to RM-057. The revised calculation is contained in RP-AA-l1010 FC-1 5-003 (RA 13-008) Rev. 1.

FC-RAI-09 For ICe RAl and RU1, Table Rl, "Effluent Monitor Thresholds for Alert Classification,"

provides values for RM-043, RM-052, and RM-062 that are not significantly higher than the values provided by Table R3, "Effluent Monitor Thresholds for Unusual Event Classification." Please validate all RA1 and RUl threshold values and revise accordingly. This validation should include verification of appropriate separation between Unusual Event, Alert, Site Area Emergency, and General Emergency declarations.

FC-RAI-09 Response A review and recalculation of thresholds for RUl and RA1 using the same isotopic mixture for both initiating conditions has resolved the issue with classification escalation, the revised values provide for proper progression between RU1 and RAI and have been used to update RIA1 and RUl. The revised calculation is contained in RP-AA-1010 FC-15-.003 (RA 13-008) Rev. 1.

FC-RAJ-1 0 For IC RUI, the proposed EAL 1 uses Table 2, "Effluent Monitor Thresholds," which provides "2X High Alarm set point" as threshold values. Additionally, the proposed EAL 2 uses Table R3, "Effluent Monitor Thresholds," as threshold values. As provided, Table R2 is a subset of Table R3 with Iwo exceptions. T"he exceptions are the thresholds for

LIC-1 5-0102 Enclosure Page 6 RM-052 and RM-062 on Table R3, which are significantly higher than the threshold values for RM-052 and RM-062 on Table R2.

a. Please justify using two tables that use different values to perform classifications for RU1 or revise accordingly.

b. Please explain the significant difference in the Table R2 and Table R3 threshold values for RM-052 and RM-062, or revise accordingly.

FC-RAI-10 Response Upon review the following changes were made to Table R2 and R3.

1. RUI EAL 1 contains effluent monitors that monitor non-continuous batch releases covered by discharge permits at FOS, the applicable effluent monitors are contained within the provided revised Table R2.

2. Radiation monitors RM-052 and 62, depending on which may be aligned to the auxiliar*i building exhaust stack, are only contained in the revised Table R3. Although these monitors may be used as the Waste Gas Decay Tank Release monitor for batch gas releases they are also the gaseous effluent monitors used for the continuous auxiliary building exhaust stack release, as such the RUl EAL 2 threshold in the revised Table R3 bounds both conditions.

3. RUl EAL 2 contains continuous release .patheffluent monitors, the applicable effluent monitors are contained within the provided revised Table R3.

FC-RAI-,11 For IC RUI, Table R3 is used to assess EAL #2, which includes both liquid and gaseous radioactivity radiation monitors. However, the RU1 basis discussion for EAL #2 only discusses gaseous radioactivity releases. Please explain why EAL #2 Basis discussion excludes liquid radioactivity releases.

FC-RAI-1 1 Response This has been corrected, RUt EAL #2 basis discussion now addresses both gaseous and liquid radioactivity releases.

FC-RAI-1 2 For IC RUl, Table R3 in Attachment 2, Enclosure 2C, "EAL Basis Document,' is different than Table R3 in the Attachment 2, Enclosure 2A, "EAL Comparison Matrix Document";

specifically:

• RM-043, RM-052, RM-062, and RM-057 have different values between the two tables; and

• RM-063 is included in Table R3 in the Attachment 2, Enclosure 2A, "EAL Comparison Matrix Document," and Table R3 in Attachment 2, Enclosure 2B, "EAL Red-Line Basis Document, but is not included in Table R3 of EAL RU1 of Attachment 2,, Enclosure 2C, "EAL Basis Document."

LIC-15-0 102 Enclosure Page 7 Please explain the apparent inconsistencies between Attachment 2, Enclosures 2A, 2B, and 2C, or revise accordingly.

FC-RlAI-1 2 Response A review has been performed on all attached documents for agreement between RUl Tables R2 and R3 and they have been revised to agree between all of the documents.

FC-RAI-1 3 The deviation for the wording in IC RU1 EAL 3 was not justified in the submittal. The addition of "Confirmed" pertains to the timeliness of EAL classification. Please provide justification for this deviation, or revise accordingly consistent with NRC-endorsed guidance.

FC-RAI-13 Response Agree, the word "Confirmed" has been removed from IC RU1 EAL 3.

FC-RAI-1 4 For lCs RA2, RS2, and RG2, the proposed EALs do not reflect enhanced spent fuel pool level instrumentation. Please provide EALs reflecting the planned installation of enhanced spent fuel pool level instrumentation for NRC pre-approval, or provide justification for not including at this time.

FC-RAI-14 Response Revised the sites proposed EALs to contain the associated RG2, RS2 and additional RA2 threshold related to the enhanced SFP level indicators being installed per NRC Order- EA 051. These EALs will be incorporated into the site's EAts when the enhanced spent fuel pool level instrumentation is available for use, in accordance with the discussion in Section 1.4, NRC Order EA-1 2-051.

FC-RAI-1 5 For IC RU2, the proposed EALs do not include site-specific refueling pathway level indications per NEK 99-01, Revision 6. Please provide site-specific level indications for RU2 that could be used to support timely and accurate assessments, including applicable mode availability for level instrumentation.

FC-RAI-15 Response Agree, the applicable refueling pathway instrumentation has been added to EAL RU2.

FC-RAI-1 6 For IC RA2, the proposed Basis discussion does not include the NEI 99-01, Revision 6, EAL AA2 guidance stating: "This IC applies to irradiated fuel that is licensed for dry storage up to the point that the loaded storage cask is sealed. Once sealed, damage to a loaded cask causing loss of the CONFINEMENT BOUNDARY is classified in accordance

LIC-1 5-0102 Enclosure Page 8 with IC E-HUI." Please justify excluding theNEi 99-01, Revision 8, EAL AA2 guidance that relates to RA2 applicability, or revise accordingly.

FC-RAI-1 6 Response Agree, the paragraph has been irncluded in EAL RA2 basis discussion as follows:

"This IC applies to irradiated fuel that is licensed for dry storage up to the point that the loaded storage cask is sealed. Once sealed, damage to a loaded cask causing loss of the CONFINEMENT BOUNDARY is classified in accordance with IC E-HU1Y.

FC-RAI-1 7 Please provide verification that the areas identified for IC RA3 reflect only those areas required for normal plant operations, cooldown or shutdown, or revise as necessary to support accurate and timely assessment. In addition, the note for the RA3 EAL references Table R4 versus Table R7. Please verify which table should be referenced, and revise accordingly.

FC-RAI-1 7 Response A) Amended the sites mode dependent areas Table in RAS to ensure that the stated areas are limited to those where access is required to operate equipment necessary for normal operations, safe shutdown, and cooldown. Areas that do not contain equipment requiring local operation are no longer reflected in these Tables.

B) Added the following highlighted words to the RA3 basis section to ensure that the EAL Basis reflects that equipment for normal operation, safe shutdown, and cooldown is the concern of the EAL.

uAssuming all plant equipment is operating as designed, normal operation is capable from the Main Control Room (MCR). The plant is also able to transition Into a hot shutdown condition from the MCR. therefore Table R6 is a list of plant rooms or areas with entry-related mode applicability that contain equipment which require a manuaL/local action necessary to transition the plant from normal plant operation to cooldown and shutdown as specified in normal operating procedures (establish shutdown cooling), where if this action is not completed the plant would not be able to attain and maintain cold shutdown."

C) The note for the RA3 EAL now references the correct Table number reference.

FC-RAI-1 8 For IC FRU3, please provide justification for including the statement:" ... as determined by laboratory confirmation ... "in the plant-specific basis for declaration of an Unusual Event with elevated coolant activity, or revise accordingly consistent with NRC-endorsed guidance, as this could impact the timeliness of the assessment.

LIC-1 5-0102 Enclosure Page 9 FC-RAI-18 Response Agree, the following paragraph has been removed from RU3.

• "An Unusual Event is only warranted when actual fuel clad damage is the cause of the elevated coolant sample activity (as determined by laboratory cornlirmatlon). Fuel clad damage should be assumed to be the cause of elevated Reactor Coolant activity unless another cause is known,"

FC-RAl-i 9 Address the following under IC RC1, Potential Loss:

a. The proposed Fission Product Barrier (FPB) Threshold Potential Loss 2 does not reflect steam generator tube leakage, which could impact the ability to perform accurate and timely assessments. Please provide justification for this deviation, or revise accordingly consistent with NRC-endorsed guidance.

b. The proposed FPB Threshold Potential Loss 2 deviates from NRC-endorsed guidance in that, "Operation of a standby charging (makeup) pump is required."

The licensee proposes the following wording: "> the capacity of one charging pump in the normal mode (greater than 40 gpm [gallons per minute])." Please provide justification for this change, or revise accordingly, as it could imply that operators must determine an actual leak rate of 40 gpm or greater rather than determine that a second charging pump is required due to either an unisolable reactor coolant system (RCS) leak or steam generator tube leakage.

c. The proposed FPB Threshold Potential Loss 3 is related to a heat removal challenge and not "UNISOLABLE RCS leakage." Please provide further justification for this deviation, or revise consistent with NRC-endorsed guidance.

FC-RAI-19 Response

a. Agree, S/G tube leakage is now reflected in RC! Potential Loss threshold #2.

b. The following justification has been added to the Comparison Matrix:

The words "> the capacity of one charging pump in the normal mode (greater than 40 gpm)" is used since this would beathe earliest time that an additional charging pump could be aligned and discriminates the use Of reduced letdown flow (non-normal mode) to allow for a net increased capacity of a single charging pump as allowing continued operation without EAL declaration.

c. Agree, removed Potential Loss 3 from the RCS /S/G tube leakage sub category for RCS loss.

FC-RAI-20 For CT!, the proposed FPB Threshold Loss 1 deviates from NRC-endorsed guidance that, "A leaking or RUPTURED SG [steam generator)is FAULTED outside of containment." The licensee proposes the following wording: "> the capacity of one charging pump in the normal mode (greater than 40 gpm)." Please provide justification for this deviation, or revise consistent with NRC-endorsed guidance, as it implies that operators must determine an actual leak rate of 40 gpm or greater rather than determine that a second charging pump is required for a steam generator tube leak.

L C_-115-0102 Enclosure Page 10 FC-RAI-20 Response Agree, revised the wording to UA leaking or RUPTURED SG is FAULTED outside of containment" to be consistent with the endorsed guidance.

FC-RAI-21 For CT2, FPB Threshold Potential Loss la. threshold is provided as Tclad > 1550 degrees. Please verify that Tclad can be determined by the operators in a timely manner, or revise accordingly.

FC-RAl-21 Response Reviewed and revised to Core Exit Thermocouples, not T clad.

FC-RAI-22 For CT4, FPB Threshold Potential Loss 3 includes "and rising." This deviation could impact the timeliness and accuracy of classification. Provide justification for this deviation, or revise accordingly consistent with NRC-endorsed guidance.

FC-RAI-22 Response The following justification was added to the comparison matrix:

=Adde "and rising" to Potential Loss #3 to distinguish the transient condition where Containment Pressure may have exceeded the design pressure momentarily on a transient but due to containment safety equipment is now being reduced to below the design pressure, this type of condition would not be a potential threat to containment. Whereas exceeding design pressure with an increasing trend would pose a threat to containment."

FC-RAI-23 For CT4, FPB Threshold Potential Loss 5 does not include a 15 minute criteria for less than one train of containment spray. Provide additional justification for this deviation or revise accordingly consistent with NRC-endorsed guidance.

Fc-RAI-23 Response Agree, "per design for > 15 minutes" has been added to CT4 Potential Loss Threshold #5.

FC-RAI-24 For ICs MU3, MA3, and MS3, please justify why the words: "... as indicated by reactor power > 2%," were added to the EALs, or revise accordingly. Relying solely on a reactor power level of 2 percent is not consistent with EOP criteria as provided by NEt 99-01, Revision 6.

LIC-1 5-0102 Enclosure Page 11 FC-RAI-24 Response Revised to add T=and SUR is negative" to the existing reactor power indication to be consistent with guidance provided in EOPs.

FC-RAI-25 For IC MA3, please explain why "or manual" was not included in the third paragraph of the Basis discussion when the EAL includes both automatic and manual trips, or revise accordingly.

FC-RAI-25 Response Agree, "or manual" has been included in the 3rd paragraph of the Basis discussion.

FC-RAI-26 For IC MA4, under Table M2, "Significant Transients," please explain the following or revise accordingly:

a. Why the proposed Table M2 includes "ECCS [Emergency Core Cooling System)

Actuationer oscillations > 10%" versus "ECCS Actuation," as provided by NEi 99-01, Revision 6 and Attachment 2, Enclosure 2A, "EAL Comparison Matrix Document"?

b. Why the proposed Table M2 does not include a manual runback of greater than 25 percent?

FC-RAI-26 Response

a. Agree and proposed Table M2 corrected to stale "ECCS ActuationD on all enclosures.

b. FCS is not equipped with automatic or manual runback capability.

FC-RAI-27 For IC CU4, please explain why EAL #2 Basis does not include a procedure number, or revise accordingly.

FC-RAI-27 Response Agree and procedure number FC-1 188, Event Notification Form, has been added to the basis for CU4 EAL #2.

FC-RAI-28 For IC CU5, please explain how the addition of ".... due to the loss of decay heat removal..." to EAL 1 would not result in potential misclassification for an event other than a loss of decay heat removal that leads to an unplanned RCS temperature and/or RCS/reactor pressure vessel (RPV) pressure to rise. Please provide justification, or revise accordingly consistent with NRC-endorsed guidance.

LIC-1 5-0102 Enclosure Page 12 FC-RAI-28 Response Agree, the following has been removed from GU5 EAL =...due to loss of decay heat removal" And Added the following Note to CU5 to allow for quick reference by the SM / EDO since it will show on the 1 1x17 Procedure Matrix EALs:

S"A momentary UNPLANNED excursion above the Technical Specification cold shutdown temperature limit when heat removal function is available does not warrant classification" FC-RAI-29 For IC CA5, please explain how the addition of "... due to the loss of decay heat removal ..." to EAL 1 and, "... as a result of temperature rise due to loss of heat removal..."

to EAL 2, would not result in potential misclassification for an event other than a loss of decay heat removal that leads to an unplanned RCS temperature and/or RCS/RPV pressure to rise. Please provide justification, or revise accordingly consistent with NRC-endorsed guidance.

FC-RAI-29 Response Agree, the following has been removed from CA5 EAL "...due to loss of decay heat removal"

. And Added the following Note to GA5 to allow for quick reference by the SM / EDO since it will show on the 1lx17 Procedure Matrix EALs:

• 'A momentary UNPLANNED excursion above the Technical Specification cold shutdown temperature limit when heat removal function is available does not warrant classification" FC-RAI-30 For IC CG6, no justification is provided for the difference between the pr;oposed EAL and the guidance of NEi 99-01 Revision 6. Specifically, the endorsed guidance has two EAI~s, whereas the licensee proposes three EALs. [Note: The major difference is the numbering scheme and not the actual content of the EALs.] This change introduces a potentially different logic methodology, which could impact timeliness and accuracy of assessments. Please provide justification that the proposed changes will not impact the timeliness or accuracy of assessment, or revise accordingly consistent with NRC-endorsed guidance.

FC-RAI-3D Response Agree and this has been corrected. The EAL now contains EAL 1 and EAL 2 a., b. (with three bullets under it), and c. This coincides with the endorsed NEI 99-01 Rev. 6 CG1 IC. No content has changed.

LIC-1 5-0102 Enclosure Page 13 FC-RAI-31 For ICs CU6, CA6, CS6, and CG6, please provide further justification as to why the EALs for Reactor Vessel/Reactor Pressure Vessel Level are not in accordance with the guidance in NEI 99-01, Revision 6, or revise accordingly. The RCS level criterion was changed from "cannot be monitored" to "unknown". This change could impact the start time from the moment when the indication is lost to a judgment as to when RCS level becomes "unknown," which could impact the timeliness of the assessment.

FC-RAI-31 Response Agree, wording returned to "cannot be monitored."

FC-RAI-32 For IC CS6, please provide verification that FCS has both a Reactor Vessel Level Measurement System (RVLMS), as indicated in EAL #1, and a Reactor Vessel Level Indicating System (RVLIS), as indicated in EAL #2, or revise accordingly.

FC-RAI-32 Response Agree, corrected to reflect the FCS RVLMS only.

FC-RAI-33 For IC CA6, the Basis for EAL #1 provides "water level below 0 inches on Draindown Level indicator" as an indication that operator actions have not been successful in restoring and maintaining RCS level. Please explain why the basis for EAL #1 refers to a Draindown level indicator, when EAL #1 refers to an RVLMS level, or revise accordingly.

FC-RAI-33 Response Agree, CA6 Basis for EAL #1 corrected to reflect 14% RVLMS and now agrees with EAL #1.

FC-RAI-34 For IC HG1, the NRC staff is not clear of the intent of the last sentence in the Basis which states: "contained in non-public documents such as the Security Plan." Please revise accordingly to clarify.

FC-RAI-34 Response Agree, this sentence has been removed from HGt Basis.

FC-RAI-35 For IC HUJ3, the proposed EALs appear to cover a wider range than required by Appendix R. Please provide verification that the areas identified for this EAL are consistent with Appendix R guidance, or revise as necessary to support accurate and timely assessment.

LIC-15-0 102 Enclosure Page 14 FC-RAI-35 Response Agree, the table has been reviewed against the Appendix R guidance as well as the NFPA 805 analysis and has been revised to agree with this guidance.

FC-RAI-36 For IC HU3, please provide justification for deviation in excluding a fire within the independent spent fuel storage installation, or revise accordingly consistent with NRC-endorsed guidance.

FC-RAI-36 Response The Comparison matrix for HU3 now reflects the fact that the ISFSI is within the plant PROTECTED AREA and as such is not specifically contained within EAL #3 and #4.

And The following sentence has been added to the basis section of HU3.

• "ISFSI is not specifically addressed in EAL #3 and #4 since it is within the plant PROTECTED AREA."

FC-RAI-37 For IC H4U4, please verify that the "Strong Motion Seismic Event in Progress" alarm and the event indicator (SMA Control Panel) of an Operating Basis Earthquake are indicated in the Control Room.

FC-RAI-37 Response Verified and stated the alarm and event indicator indicate in the Control Room, this information is listed in the comparison matrix under the H-fU4 justifitation column.

FC-RAI-38 For IC HA5, please verify the areas identified for this EAL were developed in accordance with the NRC-endorsed guidance and reflect only those areas required for normal plant operations, cooldown or shutdown.

FC-RAI-38 Response A) Amended the sites mode dependent areas Table in HA5 to ensure that the stated areas are limited to those where access is required to operate equipment necessary for normal operations, safe shutdown, and cooldown. Areas that do not contain equipment requiring local operation are no longer reflected in these Tables.

B) Added the following highlighted words to HA5 basis section to ensure that the EAL Basis reflects that equipment for normal operation, safe shutdown, and cooldown is the concern of the EAL.

LIC-1 5-0102 Enclosure Page 15 "Assuming all plant equipment is operating as designed, normal operation is capable from the Main Control Room (MCR). The plant is also able to transition into a hot shutdown condition from the MCR, therefore Table H3 is a list of plant rooms or areas with entry-related mode applicability that contain equipment which require a manual/local action necessary to transition the plant from normal plant operation to cooldown and shu~tdown as specified in normal operating procedures (establish shutdown cooling), where if this action is not completed the plant would not be able to attain and maintain cold shutdown."

FC-RAI-39 For IC HU6, the EAL #2 Basis discussion on "Manual isolation of power to ... " appears to contradict the information in EAL #2 and is not in accordance with NRC-endorsed guidance. Please provide clarification, or revise accordingly.

FC-RAI-39 Response Agree, removed the following from HU6 EAL #2 basis information:

• 1 Manual isolation of power to a SAFETY SYSTEM component as a result of leakage is an event of lesser impact and would be expected to cause small and localized damage. The consequence of this type of event is adequately assessed and addressed in accordance with Technical Specifications."

The first four are the UNUSUAL EVENT (UE), ALERT, SITE AREA EMERGENCY (SAE), and GENERAL EMERGENCY (GE). These ECLs are entered by satisfying the Initiating .Condition (IC) through meeting an Emergency Action Level (EAL) of the IC provided in this section of the Annex. The ECLs are escalated from least severe to most severe according to relative threat to the health and safety of the public and emergency workers.

UNUSUAL EVENT (UE): Events are in progress or have occurred which indicate a potential degradation of the level of safety of the plant or indicate a security threat to facility protection has been initiated. No releases of radioactive material requiring offsite response or monitoring are expected unless further degradation of safety systems occurs.

ALERT: Events are in progress 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.

SITE AREA EMERGENCY (SAE): Events are in progress or have occurred which involve an actual or likely major failures of plant functions needed for protection of the public or HOSTILE ACTION that results in intentional damage or malicious acts; 1) toward site personnel or equipment that could lead to the likely failure of or; 2) that prevent effective access to equipment needed for the protection of the public. Any releases are not expected to result in exposure levels which exceed EPA Protective Action Guideline exposure levels beyond the site boundary.

GENERAL EMERGENCY (GE): Events are in progress 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 Guideline exposure levels offsite for more than the immediate site area.

EMERGENCY CLASSIFICATION LEVEL (ECL): One of a set of names or titles established by the US Nuclear Regulatory Commission (NRC) for grouping off-normal events or conditions according to (1) potential or actual effects or consequences, and (2) resulting* onsite and offsite response actions. The emergency classification levels, in ascending order of severity, are:

• UNUSUAL EVENT (UE)

• ] ALERT

• SITE AREA EMERGENCY (SAE)

• ] GENERAL EMERGENCY (GE)

INITIiATING CONDITION IC):An event or condition that aligns with the definition of one of the four EMERGENCY CLASSIFICATION LEVELS by virtue of the potential or actual effects or consequences.

EMERGENCY ACTION LEVEL (EAL)I: A pre-determined, site-specific, observable threshold for an INITIATING CONDITION that, when met or exceeded, places the plant in a given EMERGENCY CLASSIFICATION LEVEL.

An emergency is classified by assessing plant conditions .and comparing abnormal conditions to ICs and EALs, based on the designated Operational Condition (MODE). Modes 1 through 5 are defined in the Technical Specifications (T.S). "Defueled" Mode (D) was established for classification purposes to reflect conditions where all fuel has been removed from the Reactor Pressure Vessel.

FCS does not use Standard Technical Specifications for CE PWRs. FCS does not use an operating mode for plant conditions with the reactor subcritical, Tcold greater than or equal to 210 °F, and Tavg less than or equal to 515°F, the only difference between FCS Modes 4 and 5 is the reactor coolant boron concentration, and FCS does not have a defueled mode. To ensure the intent of the NEI 99-01 scheme is met, the following stipulation is added that states:

"Unless specific criteria are identified in the "Applicable Modes" section of an EAL, the plant shall always assume to be in the higher Operating Mode (numerically lower) during transitions between modes for the purposes of Emergency Classification (i.e., if Tcold is 246°F, the plant is considered to be in Operating Mode 3 if no temperatures are specified)."

U U1 f1 fltalvii-t I5./OLIl11.4 Individuals responsible for the classification of events will refer to the Initiating Condition and EALs on the matrix of this document. This matrix will contain l~s, EALs, Mode Applicability Designators, appropriate EAL numbering system, and additional guidance necessary to classify events, it may be provided as a user aid.

The matrix is set up in six Recognition Categories. The first is designated as "R" and relates to Abnormal Radiological Conditions / Abnormal Radiological Effluent Releases. The Second is designated as "F" and relates to Fission Product Barrier Degradation. The third is designated as "M" and relates to hot condition System Malfunctions. The fourth is designated as "CU and relates to Cold Shutdown /

Refueling System Malfunctions. The fifth is designated as "H" and relates to Hazards and Other Conditions Affecting Plant Safety. The sixth is designated "E-H" and relates to ISFSI Malfunctions.

The matrix is designed to provide an evaluation of the Initiating Conditions from the worst conditions (General Emergencies) on the left to the relatively less severe conditions on the right (Unusual Events). Evaluating conditions from left to right will reduce the possibility that an event will be under classified. All Recognition Categories should be reviewed for applicability prior to classification.

The Initiating Conditions are coded with a two letter and one number code. The first letter is the Recognition Category designator, the second letter is the Classification Level, "Un for (NOTIFICATION OF) UNUSUAL EVENT, UA"~for ALERT, "S"I for SiTE AREA EMERGENCY and "G" for GENERAL EMERGENCY.

The EAL number is a sequential number for that Recognition Category series. All ICs that are describing the severity of a common condition (series) will have the same number.

The EAL number may then be used to reference a corresponding page(s), which provides the basis information pertaining to the IC:

• , EAL

,, Mode Applicability

• , Basis Classification is not to be made without referencing, comparing and satisfying the specified Emergency Action Levels.

A list of definitions is provided as part of this document for terms having specific meaning to the EALs.

References are also included to documents that were used to develop the EALs.

Ft. Calhoun Station Omaha Public Power District References to the Emergency Director means the person in Command and Control as defined in the Emergency Plan. Classification of emergencies is a non-delegable responsibility of Command and Control with responsibility assigned to the Shift Manager (Main Control Room), the Control Room Coordinator (Main Control Room), the TSC Site Director (Technical Support Center), or the EOF Emergency Director (Emergency Operations Facility).

Although the majority of the EALs provide very specific thresholds, the Emergency Director must remain alert to events or conditions that lead to the conclusion that exceeding the EAL is IMMINENT. If, in the judgment of the Emergency Director, an IMMINENT situation is at hand, the classification should be made as if the EAL has been exceeded. While this is particularly prudent at the higher ECL (as the early classification may provide for more effective implementation of protective measures), it is nonetheless applicable to all ECLs.

3.2 Classification, Instrumentation and Transient Events All classifications are to be based upon valid indications, reports or conditions.

Indications, reports or conditions are considered valid when they are verified by (1) an instrument channel check, or (2) indications on related or redundant indications, or (3) by direct observation by plant personnel, such that doubt related to the indication's operability, the condition's existence, or the report's accuracy is removed. Implicit in this is the need for timely assessment.

Indications used for monitoring and evaluation of plant conditions include the normally used instrumentation, backup or redundant instrumentation, and the use of other parameters that provide information that supports determination if an EAL has been reached. When an EAL refers to a specific instrument or indication that is determined to be inaccurate or unavailable, then alternate indications shall be used to monitor the specified condition.

During an event that results in changing parameters trending towards an EAL classification, and instrumentation that was available to monitor this parameter becomes unavailable or the parameter goes off scale, the parameter should be assumed to have been exceeded consistent with the trend and the classification made if there are no other direct or indirect means available to determine if the EAL has not been exceeded.

The assessment of some EALs is based on the results of analyses that are necessary to ascertain whether a specific EAL has been exceeded (e.g., dose assessments, chemistry sampling, ROS leak rate calculation, etc.); the EAL andlor the associated basis discussion will identify the necessary analysis. In these cases, the 15-minute declaration period starts with the availability of the analysis results that show the EAL to be exceeded (i.e., this is the time that the EAL information is first available).

Month 20xx FC 3-5 Mont 2Ox FC3-5EP-XX-XXXX (Revision xx)

Ft. Calhoun Station Public Power District Ft. alhon SttionOmaha Planned evolutions involve preplanning to address the limitations imposed by the condition, the performance of required surveillance testing, and the implementation of specific controls prior to knowingly entering the condition in accordance with the specific requirements of the site's Technical Specifications.

Activities which cause the site to operate beyond that allowed by the site's Technical Specifications, planned or unplanned, may result in an EAL being met or exceeded. Planned evolutions to test, manipulate, repair, perform maintenance or modifications to systems and equipment that result in an EAL being met or exceeded are not subject to classification and activation requirements as long as the evolution proceeds as planned and is within the operational limitations imposed by the specific operating ticense. However, these conditions may be subject to the reporting requirements of 10 CFR 50.72.

When two or more EAts are determined, declaration will be made on the highest classification level.

Concerning ECL Downgrading, OPPD Nuclear policy is that ECts shall no_.t be downgraded to a lower classification. Once declared, the event shall remain in effect until no Classification is warranted.

There may be cases in which a plant condition that exceeded an EAL was 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), and the condition no longer exists. tn these cases, an emergency Should not be declared. Reporting requirements of 10 CFR 50.72 are applicable, the guidance of NUREG-1022, Event Reporting Guidelines 10 CFR 50.72 and 50.73 and the Reportability Reference Manual, should be applied.

3.3 Mode Applicability The plant-operating mode that existed at the time that the event occurred, prior to any protective system or operator action initiated in response to the condition, is compared to the mode applicability of the EALs. If an event occurs, and a lower or higher plant-operating mode is reached before the emergency classification can be made, the declaration shall be based on the mode that existed at the time the event occurred.

For events that occur in Cold Shutdown or Refueling, escalation is via EALs that have Cold Shutdown or Refueling for mode applicability, even if Hot Shutdown (or a higher mode) is entered during any subsequent heat-up. In particular, the Fission Product Barrier Matrix EALs are applicable only to events that initiate in Hot Shutdown or higher.

If there is a change in Mode following an event declaration, any subsequent events involving EAts outside of the current declaration escalation path will be evaluated on the Mode of the plant at the time the subsequent events occur.

Ft. Calhoun Station Ft. aihon SttionOmaha Public Power District 3.4 Emergency Director Judgment Emergency Director (ED) Judgment EALs are provided in the Hazards and Other Condition Affecting Plant Safety section and on the Fission Product Barrier (FPB)

Matrix. Both of the ED Judgment EALs have specific criteria for when they should be applied.

The Hazards Section ED Judgment EALs are intended to address unanticipated conditions which are not addressed explicitly by other EALs but warrant declaration of an emergency because conditions exist which are believed by the ED to fall under specific emergency classifications (UE, Alert, SAE or GE).

The FPB Matrix ED Judgment EALs are intended to include unanticipated conditions, which are not addressed explicitly by any of the other FPB threshold values, but warrant determination because conditions exist that fall under the broader definition for a significant Loss or Potential Loss of the barrier (equal to or greater than the defined FPB threshold values).

3.5 Fission Product Barrier (FPB) Threshold A fission product barrier threshold is a pre-determined, site-specific, observable threshold indicating the loss or potential loss of a fission product barrier.

FPB thresholds represent th'reats to the defense in depth design concept that precludes the release of radioactive fission products to the environment. This concept relies on multiple physical barriers, any one of which, if maintained intact, precludes the release of significant amounts of radioactive fission products to the environment, The primary FPBs are:

EU Fuel Clad (FC)

• Reactor Coolant System (RCS)

[] Containment (CT)

Upon determination that one or more FPB thresholds have been exceeded, the combination of barrier loss and/or potential loss thresholds is compared to the FPB IC/EAL criteria to 'determine the appropriate ECL.

In some accident sequences, the ICs and EALs presented in the Abnormal Radiation Levels/ Radiological Effluent (R) Recognition Category will be exceeded at the same time, or shortly after, the loss of one or more fission product barriers. This redundancy is intentional as the former ICs address radioactivity releases that result in certain offsite doses from Whatever cause, including events that might not be fully encompassed by fission product barriers (e.g., spent fuel pool accidents, design containment leakage following a LOCA, etc.).

Month 20xx FC 3-7 Mont 2Ox FC3-7EP-XX-XXXX (Revision xx)

Ft. Calhoun Station Omaha Public Power District 3.6 Fission Product Barrier Restoration Fission Product Barriers are not treated the same as EAL threshold values.

Conditions warranting declaration of the loss or potential loss of a FPB may occur resulting in a specific classifcation. The condition that caused the loss or potential loss declaration could be rectified as the result of Operator action, automatic actions, or designed plant response. Barriers will be considered re-established when there are direct verifiable indications (containment penetration or open valve has been isolated, coolant sample results, etc) that the barrier has been restored and is capable of mitigating future events.

The reestablishment of a FPB does not alter or lower the existing classification.

However the reestablishment of the barrier should be considered in determining future classifcations should plant conditions or events change.

3.7 Definitions CONTAINMENT CLOSURE: The procedurally defined actions taken to secure containment and its associated structures, systems, and components as a functional barrier to fission product release under existing plant conditions.

EXPLOSION: A rapid, violent and catastrophic failure of a piece of equipment due to combustion, chemical reaction or overpressurization. A release of steam (from high energy lines or components) or an electrical component failure (caused by short circuits, grounding, arcing, etc.) should not automatically be considered an explosion. Such events may require a post-event inspection to determine if the attributes of an explosion are present.

FIRE: Combustion characterized by heat and light. Sources of smoke such as slipping drive belts or overheated electrical equipment do not constitute fire.

Observation of flame is preferred but is NOT required if large quantities of smoke and heat are observed.

FISSION PRODUCT BARRIER (FPB) THRESHOLD: A preo-determined, site-specific, observable threshold indicating the loss or potential loss of a fission product barrier.

HOSTAGE: A person(s) held as leverage against the station to ensure that demands will be met by the station.

Month 20xx FC 3-8 Mont 2Ox FO3-8EP-XX-XXXX (Revision xx)

Ft. Calhoun Station Ft Clhou StaionOmaha Public Power District HOSTILE ACTION: An act toward a Nuclear Power Plant (NPP) or its personnel that includes the use of violent force to destroy equipment, take HOSTAGES, and/or intimidate the licensee to achieve an end. This includes attack by air, land, or water using guns,' explosives, PROJECTILEs, vehicles, or other devices used to deliver destructive force. Other acts that satisfy the overall intent may be included. HOSTILE ACTION should not be construed to include acts of civil disobedience or felonious acts that are not part of a concerted attack on the NPP. Non-terrorism-based EALs should be used to address such activities (i.e.,

this may include violent acts between individuals in the owner controlled area).

HOSTILE FORCE: Any individuals who are engaged in a determined assault, overtly or by stealth and deception, equipped with suitable weapons capable of killing, maiming, or causing destruction.

IMMINENT: The trajectory of events or conditions is such that an EAL will be met within a relatively short period of time regardless of mitigation or corrective actions.

NORMAL LEVELS: As applied to radiological IC/EALs, the highest reading in the past twenty-four hours excluding the current peak value.

OWNER CONTROLLED AREA (OCA): The property associated with the station and owned by the company. Access is normally limited to persons entering for official business.

PROJECTILE: An object directed toward a Nuclear Power Plant (NPP) that could cause concern for its continued operability, reliability, or personnel safety.

PROTECTED AREA: An area that normally encompasses all controlled areas within the security protected area fence.

REFUELING PATHWAY: All the cavities, tubes, canals and pools through which irradiated fuel may be moved or stored, but not including the reactor vessel below the flange.

RUPTURED: The condition of a steam generator in which primary-to-secondary leakage is of sufficient magnitude to require a safety injection.

SAFETY SYSTEM: A system required for safe plant operation, cooling down the plant and/or placing it in the cold shutdown condition, including the ECCS.

These are typically systems classified as safety-related.

SECURITY CONDITION: Any Security Event as listed in the approved security contingency plan that constitutes a threat/compromise to site security, threat/risk to site personnel, or a potential degradation to the level of safety of the plant. A SECURITY CONDITION does not involve a HOSTILE ACTION.

Meth l~ogy for Development of Radiological Efl uent Emergency Action Levels

RP-AA-1O010 FC-15-003 (IRA 13-008)

PAGE 2 OF 74 REV. 1 This anatysis documnents the methodology for development of effluent emergency action levels (EAL) from the guidance found in NEI 99-01 Rev 6. The process monitor thresholds are to be used to supplement dose assessment during the early phases of a radiological accident. This analysis supersedes all previous versions of RA-03-004. Radkg~jial Analysis RA 13-008 revision 1 is now documented in RP-AA-10a 0 FC-1,5-XXX revision 1 A revised analysis is required, because th .site is implementing a more recent version of NEI 99-01 and therefore the actin levels are being updated to:rmeet the new revision.

Revision 1 of this analysis calculates the CEDE from iodine for the thresholds readings indicatng a notificatio of unusual event conditton, These thresholds are now based on a Total Effecve Dose Equivalent for these conditions rather than whole body dose Radiation Monitor readings are also corrected for inst"ument uncertainty and differences for the range of isotopes that could be detected in the effluent (Ref. 4). The th~resholds for RM-0S4 were revised to asstume a release through a lo-pesure steam safety rather than the condenser and change is consistent wit the dose assessment program Unried RASCAL Interface (UJRI).

1) The source termn used in this calculation is based on the predominate radlonuclides that effect offite dose. These radlonuclides are *XB and Ir1l and are consistent with the Offsite Dose Calculation Manual (ODCM), The primary calibration of the effluent rad~aton montors uses '=Xe to develop monitor efficencies.

2) The initatng conditions for each EAL is basedion doses at the sit boundary of 0.1, 10, 100, and 1,000 mrern Total Effctv Dose Equivalent ('TEDE-) inone hour forte time periods found in reference (1), or 50. 50d, 5,000-mrern for the thyroid dose_ In accordance with reference (1), NOUE is based on a multtle of the high alarm effluent set point (,4<), wh~idh are approximately equal tn 0.1 mremlyr see Methods section. In the case of action levels for Alert, Site Area and General Emergency a comparison of Total Effective Dos Equ~valent (TEDE) and Committa Dose Equivalent (CDE") to the thyroid are calculte~d (Ref. 1).

3) This analysis use annual average meteorology to calcuJte monitor thresholds as defined the ODOM and normal oper'atonal alignments Norm-l alinments are used because EALs are based on the most probable accident scenano Use of average meteorology is cwisnlset wit the guidance inreference (1).

4) The mronito indcto is based on a single release pathway. A correction for instrumenet unctinty (15%) an~d a 10% tolerance to account for the differences in detector sensitiviy for the range of isotopes detected. This this correction is con'sisten wihthe O0CM meth~odology.

5) The Condenser is assumed operatioal durig a Steam: Generator Tube Rupture (SGTR) arnd: t effluent is meonitored by RM-057 or if arigned to Auxiliary Building stad< monitored by RM-063. However, if 1the site loses off-site power, the steam sefetles and atmospheric dump valves Will opens and this; reease path is monitored by RM-064;I otherwise, the evacuation pumps will remain operabional to rnaintain Condenser Vacuum. These EAts should be based on the most probably accident event, however dose assessment pertormed using actual conditions is always the most approp:riate method of classifying (reference 1).

5) The radieinde~s used inthe varous process monitrsare assumed to have a relatively fiatI energy response. The only exception is RM-064 because RM-a64 uses a GM-Detector. However, GM-detectors exhibit a flat energy response above 0.1-MeV and over respond s~hl'*y to energies below 0.1-MeV. A Nal detector is in RM-057 and these detectors are very seositive and responses accurately to very low gamma energies. All the other detectors are beta scdintlators, which exhibit flat energy response reference (9). The lowest energy typically measured at a nudlear power plant is approximately .03-MeV, the effective energy of '=Xe. Since tbese process monitors are calibrated using t~Xe, so their response will sllghtky overestimate to the acial count: rate. resultng in a conservative response* A 10% tolerance is applied to account from these potential difference and is consistent with the ODCM.

Fort Calhoun must have a formal set of theshold conditions that require plant personnel to take specific actions concerning notifying local governments when olf-orrnai indicators in the effluent monitors are recognized. The level of response and the codtin leading to these responses were evakuaedl and documnentxed NEI 99-01 Rev. 8. These guidelines were developed by NE! and endorsed by the NRC to provide a systematic approach for the basis of tihe revised EALs.

In revision 8, it was recognized that the condition described by the radiological initiating conditions (IC) might result In radiological effluenlt values beyond the operating or display range of the insteled effluent monitor. in those cases, revision B provides guidance=...

that the EAL values should be determilned with a margin sufficent to ensure that an accurate monitor reading is available. For example, an EAL monitorreading might be set at 90% to 95% of the highest accurate monitor feading. This prov~s~ii notwithstanding, ilf ih eastimatd/calculated monitor reading Is greater than approximately 110% of the highest-accuratemonitor reading, then develope, may choose not to include the monitor as an indi'cationand identify an afternate EAL threshoid"(referencel1).

The dose consequences from these events start at a small fraction of the EPA PAG e.g.,

tess th~an 10-millirer to 100-inlilirern TEDE, escalatng to those of the EPA PAG for a General Emergency. The calculatin of these ad~ion levels uses a simprlife approach to TEDE and CDE, which assumes the main radlonudkies are 1=Xe and *1. Site boundary doses are calculated using a Gaussian plume distnbutlon to determine the gross count rate or radioactive concentrations. By using, an action level 'based on a site boundary dose for a given period of time (1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />) a monitr set point (threshold) is calculated. TEDE is th sum of Intral and external radiation exposure and those isotopes noted above best estimate the major external and internal dose:,.

The todine release rate can be calculate by using the bdlne to noble gas ratio (k* 0.007 or 0.065 for secondary reeases) and mulptying it by tii noble gas release rate(Qrj.

Substituting k0.Q,= for Q~and Q* Into the TEDE equation, the following formula can be Q the gross release rate (noble gas) corresponding to the action level dlose rate (H) at the site boundary. The process radiation monitors are calibrated using '3wXe. Solvng for Q, the equation is rewritten:

The monitor set points for asNOUE is based on 2X the ODOM limit and is based on Technical Specification section 5.16 (g), at 5 times the Imit (0.1-rem/yr for Noble Gases) as set for in10 CFR 20 for members of the public (note reference (14): 10 CER 20 Appendix B ). Therefore, the dose equivalent equals 500-rn rm/yr (TEDE). The folowing calculation shows the dose in any one hour for a NOUE at2 traes the limit (reference 1):

,settng the external dose conversion factors to zero (0), the werg.hb0ng factor to 1. and using the CDE thyroid dose EAL for H . Since the FALs for an NOUE are based on 2X the TEDE annual Ilmits (500-mremn/yr) and is Wrchluded inthe TEDE calculation of CEDE a specifi thyroid dose is not calculatead (refernce 1).,

The process effluent monitors are capable of measuring Instantaneous releases of roa~ctiit that correspond to a Notification of and Unusual Event (NOUE) and in some cases a SiTE AREA emergency. When condibons escalta* the process effluent monitors will over range, and th high range accident moitors0 wif provide indicatio. The only exception is RM-043 the Radwaste Processilng Building. However, the actual source term In this building is not sfcin to cause a release tht* would require a General emergency reterenre (12).

Radiati0n monitor RM-064 is an off-line acoident irange monitor used to monitor the main steam lines and has a low efficec (30.4-cpmn/iCi/cc). Therefore, small changes in count rats will result in Larger measured cocnrain of radioactiiy. For normal levels of reactor coolant this radiation monlor is not good indict~or for cdassifiation and other opeaioa method:s should be cosdee.

For Auwilriy Building releases monitor RM.062 is th~e normally aligned monitor and will prov:de indicatio of a stack rees until the monitor exceeds 5x108-cpm, when valves flow.  ;

When the radiation level detects decreases to )es the 5x10'3 pCi/crm3 RM-062 w~il automaticaly return to normal sample flow (reference 13).

The monitor count rates or stack concentrations were! calculated using the guidelines foundl in reference (I). For example, a sustained count rote of 3.37x10 4 -cpm on RM-043 would correspond to a TEDE dose of 2x500-mrem (i,000-rrem) in one year under average mete~ological conditions,.

A Notiiation of Unusual Event (NOUE) addresses a potential or actual decrease inth level of safetyof the plant asinditd by aradlo/lcalreleases thatexceeds regutatory commitments for an extended period. Foat Calhoun has 'incorporated features intenh'ded to conlrol the release of radioactive effluents to the e'nvironment. Further, these are administrative controls established to prevent unintentional releases, or control and monitor intentional releases. These controls are loae In the Offshe Dose Calculatin Manual. The ocourrence of ext~ended, uncontrolled mrad'oective releases to the envimrnment is Indictive of degradation inthese features and/or controls.

In accordance with reference (1) readitngs that exceed two limes the Technical Speiicto limit and not terminated within 60 mwiutes; th a NOUE shall be declared.

For an ALERT emergency' classfifcation EAL, there exists a potential or actual decrease in the level of safety of the plant as Indicated by ,a radk*0oglcaI releae that exceeds regulatory commitments for an extended period. Therefore, tn accordance with reference (1) a reading on any effluent monitor that exceeds 1Q-norero TEDE or 50-mrem CDE thyroid inone hour for 15 minutes or longer an ALERT s!ait be dclared.

The Site Area emergency EA is based on radioactivity releases that result in doses at or beyond the sit boundary that exceed 10% (100-mrernihr TEDE or 500-mrem in one hour CDE) of the EPA .Protective Action Guides (PAGS) for 15-minue. Releases of this magritude are associated with the faiture of plant systems needed for th protection of the public... . I The GENERAL' emergency EA is based on releases that result indoses at or beyond the site boundary that meet or exceed the EPA Protective Acio Guides (PAGe). Publi protective actions will be necessary within 15-minutes*. Releases of this magnitude are associated wih the failure of plant systems needed for the prtcin of the public and rikely invotve fuiel damage.

Prepared b: (date) Reviewed By date) Apred By {date) 1 Problem or Issue Statement This calculation documents the methodology used to determine the Emergency Action Level (EAL) thresholds for the initiating condition (IC) AA 1 as defined in NE] 99-01 Rev. 6 for liquid effluent discharges; a release of liquid radioactivityresulting in offsite dose greater than JO mrem TEDE or SO mi-em thyroid CDE.

2 Background or Introduction NE] 99-01 Rev. 6 initiating condition AA I addresses, a release of liquid radioactivity that results in a projected dose greater than and equal to :1% of the Environmental Protection Agency (EPA) Protective Action Guides (PAG). Releases of this magnitude represent an actual or potential substantiai degradation of the level of safety of the plant and exceeds regulatory limits.

NEI 99-01 Rev. 6 provides the following generic guidance for selection of thresholds:

• Select the appropriate installed liquid monitorr

• The effluent monitor reads should correspond to a dose of 10-torero TEDE or 50-

• mrem CDE thyroid at the site specific receptor point for one-hour of exposure.

• The monitor readings will be calculated using a set of assumed data. Acceptable sources of this data include, but not limited to the RET/ODCM and values used for emergency dose assessment methodology.

• The calculation of monitor* readings will also require use of an assumed release isotopic mix: the selected mix should be the same that is employed to calculate monitor readings for IC AS I and AG].

• NE! guidance recognized that the conditions described in IC AA I may result in a radiological effluent value beyond the operating display range of the installed effluent monitor. In those cases, EALs should be determined with a sufficient margin sufficient to ensure that an accurate monitor reading is available.

RP-AA-1O1t0 FC-'14-004 Revision 0 Page 2 of 11 3 Discussions The ODCM identifies three pathways for human exposure to liquid releases from Fort Calhoun Station (FCS) to the Missouri Rivern 1)fish, 2) drinking water, and 3) Shoreline deposition. Fish are considered to be taken from the vicinity of the plant discharge. The drinking water for Omaha is located 19 miles downstream from FCS. For this calculation the drinking water pathway is considered because accident releases are acute releases and the emergency action thresholds are based on an acute exposure of one hour as described in the NEI 99-01 Rev.6 (Ref. 8.11),

4 Methodology .

4.1 This analysis develops the model used to estimate of the radion~uclide concentration and radiation monitor count rate from an ac~cidental release into the Missouri river exceeding I 0-mrem TEDE or 50-mirem CDE to the thyroid. This calculation provides a link between the effluent releases and the direct pathway to man from an acute intake of radioactive material from potable water,

: Revision 0 c==*~a,*=* iPage 3 of 11 This calculation is based on the use of simple models and is a conservative approach. The effluent is considered small with respect to the receiving water body (Missuri River) arnd rapid mixing will reduce the discharge concentration.

The initial dilution process is based on turbulent mixing produced as the effluent is introduced in the stream. This process is assumed to be relatively rapid. Large dilution on the order of 10 to 100 can be achieved (Ref. 8.2). This calculation uses a mixing coefficient of 30.8 for the Metropolitan Utility District (MUD) intake (Ref. 8.1) and is the specific receptor identified in the ODCM, The radionucl ides will undergo radioactive decay as the liquid is transported downstream. ,

The following equation from Reference 8.1 is used to calculate the TEDE and CDE from an oral intake of rid onuclides (assuming annual water intake of standard man) for a one-hour exposure:

H. U Q,.DF&'o (1)

Where He, is the effective dose equivalent for radionuclide i in units ofmtrero. U is the adult annual intake of water (730,000 mL), M is the mixing ratio of 30.8 at the point of intake for MUD (unit-less), F is the river flow at the time of discharge in mL/s, Q, is radionuclide release rate in Ci/s, DF, is the ingestion dose factor for the dose equivalent (TEDE) in units of mrem/Ci, L, is the radioactive decay constant in inverse seconds (hri'), and tp is the transit time in hours from the discharge at MUD (Ref. 8.1) intake (site specific receptor point).

The transit time tp is calculated by dividing the distance from the discharge to the point of intake (i.e.4 19 miles) (Ref. 8.1) by the river velocity v (mph) (Ref. 8.7):

19miies t,- v(mph) (2)

To calculate the release rate at the site discharge for a 10-torero TEDE or" 50-torero CDE thyroid exposure equation I is solved for Qi the isotopic release rate for an one hour exposure. The isotopic release rate is based on the fraction of the assumed radionuclide mix in the source term (0):

Q' uAMvDy,-' (3)

The isotopic fraction is calculated by dividing the assumed Ci/MWth for each isotope by the sum of the inventory: ,

A XA'.,I (4)i The assumed inventory is the accident source term employed by the Universal RASCAL Interface (URI) program; the site dose assessment program.

The threshold count rate is calculated by multiplying the radiationl monitor efficiency (cpmn/itCi/mL) by the undiluted concentration Cr (j*Ci/mL) and adding the background.

R = e*C, +Rb (7)

Instrument uncertainties and allocation factors are ignored because this eventis an acute accidental release and the EAL thresholds are not designed to provide! automatic action to prevent a release greater than a regulatory limit.

5 Assumptions 5.1 Any noble gases resulting from a radiological accident are assumed released to the atmosphere.

Basis: Noble gases are non-reactive gases and the effluent stream is open to the atmosphere at ambient temperatures; so an insignificant fraction of noble gases are assumed entrained in the effluent. In addition, as the effluent is' transported downstream entrained noble gases in the stream would be released via the turbulently river flow.

5.2 A river current of 7-mph is assumed in this analysis.

Basis: 'Reference 8.7 provides a range of river velocities between 4 to 7 miles per hour.

- The river speed is used :to calculate decay time as the effluent isi transported downstream. A higher transport velocity will result in less decay and a conservative estimate of decay.

5.3 The annual oral intake of water is based on the use factor in the 00CM (Ref. 8.1) of 730 L.

Basis: The annual intake usage factor for an adult in referencei 8.1 is 730 L which is taken from NRC Regulatory Guide 1.109 (Ref. 8.4). This intake factor is consistent with reference man's intake of~l I L given in ICRP 23 (Ref. 8.8).

5.4 Liquid releases through the plants discharge pathways have alarm set paint ealculated based on known isotopic mixtures as measured by isotopic analysis of the liquid. This calculation assumes that the effluent isotopic mixture is unknown and uses the default mix of radionuclides used by the URI dose assessment program.

Basis: By definition the EAL threshold values for this IC are for unexpected and unauthorized releases, so the isotopic mix is unknown. In accordance With NE!

99-0 1 Rev. 6 developer notes state that the source term should be based the 0DCM or emergency dose methodology. The ODCM is not an emergency release program and therefore the accident source used by the dose assessment program

6Results or Conclusions The results of the calculation show the maximum range of the liquid efflueint radiation monitors are exceeded (>1107 epta). Inaccordance with NEI 99-01] Rev. 6 alternate methods of assessment or reduction in count rates that provide a reasonable threshold should be employed. With three circula~ting water pumps running the: TEDE threshold is approximately 128% of full range operation (Table 2) and large differences for less dilution flow would occur (Attachment 2).

In accordance with guidance in NEI 99-01 Rov. 6 (page 35) alternate methods will apply since the expected radiation monitor readings for the EAL thresholds are greater than 1 10%

of full scale. These alternate methods may include grab samples from the effluent or field monitoring samples at the MUD intake.

A grab sample of from an unauthorized rele~ase of 0.4-l.Ci/cc (e.g.. run off from an uncontrolled release or tank breach) in the effluent stream is an indicator of meeting the ALERT threshold for IC AA 1 (Attachment 2).
