PNPP EAL Technical Bases Calculations - Rx1 Effluent Series 1.

PURPOSE The PNPP Emergency Action Level (EAL) Technical Bases Manual contains background information, event declaration thresholds, bases and references for the site specific EAL and Fission Product Barrier (FPB) values used to implement the Nuclear Energy Institute (NEI) 99-01 Rev. 6 EAL guidance methodology. This calculation document provides additional technical detail specific to the derivation of the gaseous and liquid radiological effluent EAL values developed in accordance with the guidance in NEI 99-01 Rev. 6.

Documentation of the assumptions, calculations and results are provided for the PNPP site specific Rx1 series EAL effluent monitor values associated the NEI 99-01 Rev 6 EALs listed below.

DEVELOPMENT METHODOLOGY AND BASES 2.1.

Threshold Limits 2.1.1.

RU1.1 Liquid Threshold Limits Guidance Criteria The RU1 Initiating Condition (IC) addresses a release of radioactivity that, for whatever reason, causes effluent radiation monitor readings to exceed 2 times the Offsite Dose

. Calculation Manual (ODCM) limit for 60 minutes or longer.

PNPP Bases The PNPP liquid effluent limits from RU1 are taken from ODCM Controls 3.11.1.1.

For individual nuclides, the limit is the concentration value specified in 10 CFR Part 20, Appendix B Table 2 Column 2.

For dissolved and entrained noble gases, the limit is 2E-4 uCi/ml total activity.

For nuclide mixtures, the limit is the summation of individual nuclide concentrations divided by their corresponding individual effluent concentration (EC) where the resulting value equals

1. (ODCM 2.2)

The PNPP RU1.1 liquid effluent EAL threshold values will be established as the High Alarm level for the monitor and will equate to 2 times the ODCM limit.

- Rx1 Effluent Series 2.1.2.

RU1.1 Gaseous Threshold Limits Guidance Criteria The RU1 Initiating Condition (IC) addresses a release of radioactivity that, for whatever reason, causes effluent radiation monitor readings to exceed 2 times the Offsite Dose Calculation Manual (ODCM) limit for 60 minutes or longer.

PNPP Bases The PNPP gaseous effluent limits for RU1.1 are taken from ODCM Control 3.11.2.1.

Note - Inhalation (internal organ) limits are not applicable for EAL threshold determination since the specified surveillance involves collection and analysis of composite samples. This after-the-fact assessment (individual uptake) could not be made in a timely manner conducive to accident classification.

Less than or equal to 500 mrem/yr to the whole body from noble gases Less than or equal to 3000 mrem/yr to the skin from noble gases The PNPP RU1.1 gaseous effluent EAL threshold values will be established as the High-High Alarm level for the monitor and will equate to 2 times the ODCM limit.

2.1.3.

RA1.1 Liquid Threshold Limits Guidance Criteria The RA1 IC addresses a release of radioactivity resulting in offsite dose greater than 10 mrem TEDE or 50 mrem thyroid CDE.

This is based on values at 1% of the EPA Protective Action Guides (PAGs).

Per NEI 99-01, the effluent monitor readings should correspond to the above dose limit at the "site-specific dose receptor point" (consistent with the calculation methodology employed) for one hour of exposure.

PNPP Bases The PNPP liquid effluent limits are based on the liquid effluent concentration values given in 10 CFR 20 Appendix B Table 2 Column 2 (see Section 2.2.1 above). The 10 CFR 20 values are equivalent to the radionuclide concentrations which, if ingested continuously over the course of a year, would produce a total effective dose equivalent of 0.05 rem (50 millirem). The EPA PAGs are based on a TEDE dose from immersion, inhalation and deposition. The 10 CFR 20 limits and the EPA limits do not represent the same type of exposure and thus cannot be compared on a one to one basis.

Additionally, significant dilution assumptions are incorporated in determining ODCM ingestion limits for liquid releases such that obtaining a dose of 10 mrem in one hour would require a discharge concentration above the effluent monitor threshold (ingestion of radioactivity from a liquid release at the site boundary is not practical).

Thus, PNPP EALs will not contain a liquid effluent monitor threshold value that equates to1%oftheEPAPAG.

PNPP EAL Technical Bases Calculations - Rx1 Effluent Series 2.1.4.

RA1.1 Gaseous Threshold Limits Guidance Criteria The RA1 IC addresses a release of radioactivity resulting in offsite dose greater than 10 mrem TEDE or 50 mrem thyroid CDE.

Per NEI 99-01, the effluent monitor readings are based on values at 1% of the EPA Protective Action Guides (PAGs) at the "site-specific dose receptor point" (consistent with the calculation methodology employed) for one hour of exposure.

The EPA PAG guidance provides for the use adult thyroid dose conversion factors; however, some states have decided to base protective actions on child thyroid CDE.

Nuclear power plant ICs/EALs need to be consistent with the protective action methodologies employed by the States within their EPZs. The thyroid CDE dose used in the IC and EALs should be adjusted as necessary to align with State protective action decision-making criteria.

PNPP Bases The PNPP gaseous effluent limits for RA1.1 are based on values that equate to an offsite dose greater than 10 mrem TEDE or 50 mrem child thyroid CDE, which are effectively 1% of the EPA Protective Action Guides (PAGs) as the State of Ohio utilizes child thyroid CDE for protective action decision making.

2.1.5.

RS1.1 Gaseous Threshold Limits Guidance Criteria The RS1 IC addresses a release of radioactivity resulting in offsite dose greater than 100 mrem TEDE or 500 mrem thyroid CDE.

This is based on values at 10% of the EPA Protective Action Guides (PAGs) at the "site-specific dose receptor point" (consistent with the calculation methodology employed) for one hour of exposure.

The EPA PAG guidance provides for the use adult thyroid dose conversion factors; however, some states have decided to base protective actions on child thyroid CDE.

Nuclear power plant ICs/EALs need to be consistent with the protective action methodologies employed by the States within their EPZs. The thyroid CDE dose used in the IC and EALs should be adjusted as necessary to align with State protective action decision-making criteria.

PNPP EAL Technical Bases Calculations - Rx1 Effluent Series 2.1.6.

RG1.1 Gaseous Threshold Limits Guidance Criteria The RG1 IC addresses a release of radioactivity resulting in offsite dose greater than 1,000 mrem TEDE or 5,000 mrem thyroid CDE.

This is based on values at 100% of the EPA Protective Action Guides (PAGs) at the "site-specific dose receptor point" (consistent with the calculation methodology employed) for one hour of exposure.

The EPA PAG guidance provides for the use adult thyroid dose conversion factors; however, some states have decided to base protective actions on child thyroid CDE.

Nuclear power plant ICs/EALs need to be consistent with the protective action methodologies employed by the States within their EPZs. The thyroid CDE dose used in the IC and EALs should be adjusted as necessary to align with State protective action decision-making criteria.

PNPP Bases The PNPP gaseous effluent limits for RG1.1 are based on values that equate to an offsite dose greater than 1,000 mrem TEDE or 5,000 mrem child thyroid CDE, which are effectively 100% of the EPA Protective Action Guides (PAGs) as the State of Ohio utilizes child thyroid CDE for protective action decision making.

2.2.

Effluent Release Points 2.2.1.

PNPP Liquid Release Points Guidance Criteria Per NEI 99-01, the RU1 IC addresses normally occurring continuous radioactivity releases from monitored gaseous or liquid effluent pathways and planned batch releases from non-continuous release pathways.

Per NEI 99-01, the RA1 IC includes events or conditions involving a radiological release, whether gaseous or liquid, monitored or un-monitored. Classification based on effluent monitor readings assumes that a release path to the environment is established.

If the associated release path to the environment has been isolated, the effluent monitor reading is no longer VALID for emergency classification purposes.

The "site-specific monitor list and threshold values" should include the effluent monitors described in emergency plan and emergency dose assessment procedures.

PNPP Bases Batch Releases (ODCM 2.1) - Batch releases from the liquid radwaste system may occur from the waste sample tank, floor drain sample tank, chemical waste distillate tank, and detergent drain tank. All of the liquid radwaste releases from these tanks go to the Emergency Service Water (ESW) discharge (See ODCM Figure 2.1-1).

Emergency Service Water (ESW) discharge will be incorporated into the EALs as a source of potential liquid discharge to the environment.

EP-EALCALC-PNPP-1401 Page 6 of 23 Rev 0

PNPP EAL Technical Bases Calculations - Rx1 Effluent Series Continuous Releases (ODCM 2.2) - PNPP does not perform continuous radioactive liquid releases. Potential leakage pathways identified in the ODCM that could result in continuous leakage to the environment should barrier systems fail are:

Residual Heat Removal (RHR) heat exchanger leakage into the ESW system.

Alternate Decay Heat Removal (ADHR) heat exchanger leakage into the SW system.

These pathways include installed monitors or are checked by periodic grab sample.

However, these sources are not engineered discharge pathways used for normally occurring continuous liquid radioactivity releases and thus are not applicable for use as a routine discharge liquid release point for EAL threshold development.

2.2.2.

PNPP Gaseous Release Points Guidance Criteria Per NEI 99-01, the RU1 and RA1 ICs address normally occurring continuous radioactivity releases from monitored gaseous or liquid effluent pathways and planned batch releases from non-continuous release pathways.

Per NEI 99-01, the RS1 and RG1 ICs include events or conditions involving a radiological release, whether gaseous or liquid, monitored or un-monitored.

Classification based on effluent monitor readings assumes that a release path to the environment is established.

If the associated release path to the environment has been isolated, the effluent monitor reading is no longer VALID for emergency classification purposes.

The "site-specific monitor list and threshold values" should include the effluent monitors described in emergency plan and emergency dose assessment procedures.

PNPP Bases Note - Site ground level elevation is 620'0". All PNPP vent gas release points are considered ground level (ODCM 3.0.2).

Note - Containment/drywell purges and vents are considered periods of increased radiological release as they are vented through the Unit 1 Vent, concurrent with normal, continuous releases (ODCM 3.0.2).

Per ODCM 3.0.2 and Figure 3.0-1, there are four separate gaseous effluent environmental release points at PNPP:

Unit 1 Vent: The Unit 1 Vent is located on the top of the Intermediate Building, Elevation 753'9".

Unit 2 Vent: The Unit 2 Vent is located on the top of the Intermediate Building, Elevation 753'9".

Off Gas Vent' The Off-Gas Vent is located on the top of the Off-Gas Building, Elevation 723'0".

Turbine Building/Heater Bay Vent' The Turbine Bldg/Heater Bay Vent is located on the top of the Heater Bay Building, Elevation 722'0".

PNPP EAL Technical Bases Calculations - Rx1 Effluent Series 2.3.

RA1.1. RS1.1 and RG1.1 Gaseous Thresholds Source Terms Guidance Criteria The calculation of monitor readings will require use of an assumed release isotopic mix, the selected mix should be the same for ICs AA1, AS1 and AG1.

PNPP Bases The accident source term in the MIDAS dose model is based on NUREG-1228 with the following MIDAS selections:

Plant Vents - DW or Containment LOCA, Gap Release, Spray Off, <212 deg F, Holdup

<1 Hour and Normal Filtration Off-Gas Vent - Containment Bypass, MSLB or Offgas Release, Gap Release, Normal Filtration Turbine Building Vent - Containment Bypass, MSLB or Offgas Release, Gap Release, No Filtration No credit is taken for source term decay. The start of release time entered into MIDAS is coincident with the time of reactor trip.

2.4.

Release Duration Guidance Criteria Per NEI 99-011, since doses are generally not monitored in real-time, it is suggested that a release duration of one hour be assumed,...

If individual site analyses indicate a longer or shorter duration for the period in which the substantial portion of the activity is released, the longer duration should be used.

PNPP Bases The PNPP effluent monitor readings are calculated for a release duration of one hour.

As a significant number of accident types, plant condition and operator action variables exist that would influence the duration of an effluent release, no site specific analysis has been performed to establish a shorter or longer release duration.

2.5.

Meteorology Guidance Criteria The effluent monitor readings should correspond to the applicable dose limit at the "site-specific dose receptor point." The "site-specific dose receptor point" is the distance(s) and/or locations used by the licensee to distinguish between on-site and offsite doses.

The selected distance(s) and/or locations should reflect the content of the emergency plan, and the procedural methodology used to determine offsite doses and protective action recommendations. This is typically the boundary of the Owner Controlled Area.

1 Release duration basis is taken from NEI 99-01 Rev 5 as NEI 99-01 Rev 6 does not provide specific guidance for this input parameter.

EP-EALCALC-PNPP-1401 Page 8 of 23 Rev 0

PNPP EAL Technical Bases Calculations - Rx1 Effluent Series Monitor readings will be calculated using a set of assumed meteorological data or atmospheric dispersion factors; the data or factors selected for use should be the same forlCsAAl, AS1 andAGL PNPP Bases The PNPP site specific meteorology used for the calculation of monitor readings is based on selections and inputs for the MIDAS dose assessment model as documented below.

2.5.1.

Wind Speed The average wind speed at the 10 meter level for PNPP was 8.4 miles per hour for the seven site years (USAR 2.3.2.1.1).

2.5.2.

Wind Direction The PNPP "site-specific dose receptor point" utilized in the derivation of the EAL effluent release thresholds has been established as the closest on-land site boundary line, which is in the NW sector at 0.17 miles or 274 meters (ODCM Table A-2).

2.5.3.

Stability Class The most predominant stability for PNPP is class "D" (USAR Table 2.3-18).

2.5.4.

Other Parameters No precipitation is assumed to occur for the duration of the release and plume transport across the EPZ.
