3 of 83 EPIP-11 ST. LUCIE PLANT 1.0 PURPOSE 1.1 This procedure identifies the responsibility and methodology to perform core damage assessment for St. Lucie Units 1 and 2. Methods for estimating core damage assessment are based upon post-accident radionuclide concentrations within the Reactor Coolant System (RCS) and containment, and other plant indicators, including core exit thermocouple temperatures, hydrogen in the RCS and in containment, and Containment High Range Radiation Monitor (CHRRM) readings.
1.2 An estimate of core damage may be used to assist in validating Protective Action Recommendations (PARs), severity of plant conditions, and/or recovery operations.
1.3 This procedure incorporates instructions for hand calculations and/or for the use of computer software in the analysis of relevant plant data following an accident.
1.4 This procedure is only used to obtain an estimate of core damage within a major fuel damage category as identified by the NRC in NUREG-0737. The categories are defined in Attachment 1 to this procedure.
1.5 A detailed discussion of the basis for the core damage assessment methodology is included in reference 2.1.2.

6 of 83 EPIP-11 ST. LUCIE PLANT 4.0 DEFINITIONS 4.1 No Core Damage refers to a core state in which the integrity of the fuel rod cladding is intact and the only release of fission products to the Reactor Coolant System is that due to pre-existing fuel rod defects and iodine spiking.
Fuel Rod Cladding Failure refers to a core state in which the fuel rod cladding of some fraction of the fuel rods in the core has failed, resulting in the release of the fission products in the fuel rod gap space of the failed fuel rods to the Reactor Coolant System.
Fuel Overtemperature Damage refers to a core state in which the fuel pellets have reached a temperature where there is a rapid movement of fission products from the fuel pellet matrix to the Reactor Coolant System.
100% Fuel Rod Clad Damage refers to the rupture of the fuel rod cladding in 100% of the fuel rods in the core and the resultant release to the Reactor Coolant System of all fission products contained in the fuel rod gap space.
100% Fuel Overtemperature Damage refers to high temperatures in the fuel pellets in 100% of the fuel rods in the core and the resultant release to the Reactor Coolant System of fission products contained in the fuel pellet matrix.
Emergency Response Data Acquisition and Display System (ERDADS) also known as the Safety Assessment System (SAS) and includes the Safety Parameter Display System (SPDS) serves as a concentrated data source that permits EOF personnel to obtain desired information (plant parameter, radiological, meteorological, etc.) in a rapid, accurate, and convenient manner.

8 of 83 EPIP-1 1 ST. LUCIE PLANT 5.0 INSTRUCTIONS (continued) 5.4 Results in terms of fuel condition should be provided to the Emergency Technical Manager (ETM), the Recovery Manager (RM), and the Emergency Coordinator (EC) as timely as possible.
- 1.
The type of core damage is described in terms of the 10 NRC categories defined in Table 1 in Attachment 1.
- 2.
In the case of radionuclide analysis, the degree of core damage is described as the percent of the fission products in the source inventory at the time of the accident which is now in the sampled fluid and therefore available for release to the environment.
CAUTION
" The assessment of core damage obtained by using the attached methodology is only an estimate. The techniques employed are only accurate to locate the core condition within one or more of the 10 categories of core damage described in Table 1 in Attachment 1.
" Core damage assessment using indicators that are readily available (e.g., CHRRM) represents only preliminary estimates. Other plant indicators (e.g., radionuclide concentrations) should be obtained to improve upon estimation of core damage.
"* Measurements obtained during rapidly changing plant conditions should not be weighed heavily into the assessment of core damage. If deemed necessary, these pertinent indicators should be measured within a minimum time period, particularly during rapidly changing conditions. It is recommended that measurements be made, if possible, when plant conditions stabilize.

CAUTION Estimates predicted by the methodology in this procedure are good if T-max remains below 1800OF during core uncovery and if the core remains uncovered for 20 minutes or longer. Estimates could be LOW if pressure during period of T-max drops to less than 100 psia within less than 2 minutes of accident initiation, a large break is indicated.

38 of 83 EPIP-11 ST. LUCIE PLANT ATTACHMENT 4 PRELIMINARY ESTIMATE OF CORE DAMAGE USING CORE EXIT THERMOCOUPLE (CET) TEMPERATURES (Page 1 of 5)
- 1.
Purpose The purpose of this section is to estimate core damage based on core exit thermocouple temperatures up to about the time when the peak core temperature reaches about 23000F. Core damage using this indicator is described by categories 2 through 4 of the seven NRC categories in Table 2, Cladding Damage Characteristics, in Attachment 1.
- 2.
Definitions A.
Cladding Failure Cladding failure is defined as a break in the fuel rod clad at least sufficient to release the internal gas pressure.
- 3.
Precautions and Limitations A.
The assessment of core damage obtained by using this method is only an estimate. The techniques employed in this section are only accurate to locate the core condition within the first four of the seven categories of core damage described in Table 2, Cladding Damage Characteristics, in Attachment 1. The methodology is based on core exit temperature data. Other plant indications may be available which can improve upon the estimation of core damage.
B.
The relationship between the core exit thermocouple temperature and the clad temperature varies with the core uncovery scenario. This procedure applies to slow core uncovery by boiloff of the coolant. For other more rapid uncovery scenarios, this procedure could yield a very low estimate of the number of ruptured rods. In general, for core uncovery at pressures below about 1200 psia, there is high confidence that at least the predicted estimate of rods are actually ruptured.

- 4.
Instructions A.
Obtain the following from the instrument recordings:
From the recording of maximum core exit thermocouple temperature as a function of time, obtain and record on Data Sheet 4-1, Record of Temperature, Pressure and Damage Estimate, the maximum temperature and the time it occurs. As many thermocouples as possible should be used, in this way equipment malfunction may be detected if a thermocouple reads greater than 1650°F or varies considerably from its neighboring thermocouples.
From the recording of Reactor Coolant System pressure as a function of time, obtain and record on Data Sheet 4-1, Record of Temperature, Pressure and Damage Estimate the pressure during the period of maximum thermocouple temperature.
B.
Select the temperature labeled curve on Figure 4-1, Percent of Fuel Rads with Ruptured Clad vs. Max Core Exit Thermocouple Temperature, which corresponds to a pressure approximately equal to or greater than the RCS pressure. Enter the abscissa (x-value) at the maximum CET temperature and read on the ordinate (y-value) the percent of the fuel rods which have ruptured clad.

- 1.
Purpose This section provides the methodology for use under post-accident plant conditions to determine the type and degree of core damage which may have occurred by using radiation dose rates measured inside the containment building using the Containment High Range Radiation Monitor (CHRRM). The radiation dose rate is related to the quantitative release of fission products from the core expressed as the percent of the source inventory at the time of the accident. The resulting observation of core damage is described by one or more of the seven categories of core damage in Table 3 in Attachment 1.
- 2.
Definitions A.
Fuel Damage For the purpose of this section, fuel damage is defined as a progressive failure of the material boundary to prevent the release of radioactive fission products into the Reactor Coolant, starting with a penetration in the zircaloy cladding.
B.
Source Inventory The source inventory is the total quantity of fission products expressed in Curies of each isotope present in either source; the fuel pellets or the fuel rod gas gap.

Precautions and Limitations A.
The assessment of core damage obtained by using the methodology in this section is only an estimate. The techniques employed in this section are only accurate to locate the core condition within one or more of the seven categories of core damage described in Table 3 in. The procedure is based on radiation dose rate. Other plant indications may be available which can improve upon the estimation of core damage. These include sample radiological analysis, incore temperature indicators, and the total quantity of hydrogen released from zirconium degradation. Whenever possible, these additional indicators should be factored into the assessment.
B.
This section relies upon radiation dose rate measurements taken from the highest readings of two high range radiation monitors located inside the containment building to determine the total quantity of fission products released from the core and therefore available for release to the environment. The amount of fission products present at the location of the monitors may be changing rapidly due to transient plant conditions. Therefore, multiple measurements should be obtained within a minimum time period and when possible, under stabilized plant conditions. Samples obtained during rapidly changing plant conditions should not be weighed heavily into the assessment of core damage.
C.
The methodology in this section is limited to the upper bound condition of fission product release from the core due to fuel overheat.
Simultaneous with fuel overheat, there may be localized fuel pellet melting within the core. The transport of the non-volatile fission products released due to melting is not known. The dose rates measured under conditions of fuel pellet melting are anticipated to exceed those shown in Figure 5-1, Containment High Radiation Monitor Dose Rate vs. Time After Trip, for major fuel overheat. However, this procedure does not attempt to identify the extent of any potential fuel melting.

Precautions and Limitations (continued)
D.
This section is limited to the interpretation of the dose rate measurement resulting from a mix of fission products. The methodology cannot accurately distinguish between the conditions of fuel cladding failure and fuel overheat when the resulting dose rates are the same. The methodology does provide an upper limit estimate of the progressive core damage. Concurrent conditions of cladding failure and overheat should be anticipated due to the radial distribution of heat generation within the core. Distinction between the type of core damage requires the identification of the characteristic fission products.
The procedure for core damage assessment using radiological analysis of fluid samples is required to explicitly distinguish between the categories.
E.
This methodology is limited in applicability to those conditions in which the fission product inventory in the core has had sufficient time to reach equilibrium. Equilibrium fission product inventory is a function of reactor power and burnup. Based upon the fission products of concern, equilibrium conditions are achieved after thirty days of operation at constant power. Constant power is considered to include changes of no greater than +/- 10 percent. The methodology may be used following non-constant periods of operation by using engineering judgement to select the most representative power level during the period. This method may also be used if the reactor has produced power for less than thirty days, however, the resulting assessment of core damage would be an under-prediction of the actual conditions.

Instructions A.
Record the plant indications required in Data Sheet 5-1, Containment High Radiation Monitor vs. Time After Trip.
B.
Plant Power Correction The measured radiation dose rate inside the containment building is to be corrected for the plant power history. A correction factor is used to adjust the measured dose rate to the corresponding value had the plant been operating at 100 percent power.
To correct the radiation dose rate for the case in which plant power level has remained constant for a period greater than 30 days, a simple ratio of the power may be employed. The reactor power is considered to be constant if it has not changed by +/- 10 percent within the last thirty days prior to the reactor trip.
To correct the radiation dose rate for the case in which reactor power level has not remained constant during the 30 days prior to the reactor shutdown, engineering judgement is used to determine the most representative power level. The following guidelines should be considered in the determination.
The average power during the 30 day time period is not necessarily the most representative value for correction to equilibrium conditions.
The last power levels at which the reactor operated should weigh more heavily in the judgement than the earlier levels.
Continued operation for an extended period should weigh more heavily in the judgement than brief transient levels.
In the case in which reactor has produced power for less than 30 days, this procedure may be employed. However, the estimate of core damage obtained under this condition may be an under-prediction of the actual condition.

C.
The decay correction for the radiation dose rate requires the determination of the time duration between the reactor trip and the measurement of the dose rate. This is done simply using the time of reactor shutdown (trip) recorded in Data Sheet 5-1, Containment High Radiation Monitor vs. Time After Trip.
- 5.
Conclusions The conclusion on the extent of core damage is made using the equilibrium dose rate, the duration of reactor shutdown (hours since reactor trip), and the analytically determined dose rates provided in Figure 5-1, Containment High Radiation Monitor vs. Time After Trip. The equilibrium dose rate is plotted as a function of time following reactor shutdown. Engineering judgement is used to determine which category of core damage shown on Figure 5-1, Containment High Radiation Monitor vs. Time After Trip, is most representative of the particular value that has been plotted. The following criteria should be considered in the determination.
A.
Dose rate measurements may have been recorded during periods of transient conditions within the plant. Measurements made during stable plant conditions should weigh more heavily in the assessment of core damage.
B.
Dose rates significantly above the lower bound for the category of major fuel overheat may indicate concurrent fuel pellet melting. The methodology in this section may not be employed to estimate the degree of fuel pellet melting.
C.
Dose rates within any category of fuel overheating may be anticipated to include concurrent fuel cladding failure. The methodology in this section may not be used to distinguish the relative contributions of the two categories to the total dose rate. The methodology does give the estimate of the highest category of damage.
D.
Dose rates corresponding to the two categories of major cladding failure and initial fuel overheat are observed to overlap on Figure 5-1, Containment High Radiation Monitor vs. Time After Trip. The evaluation of other plant parameters may be required to distinguish between them. However, concurrent conditions may be anticipated.

Purpose This section provides the methodology for use under post-accident plant conditions to determine the extent of fuel clad damage which may have occurred. It utilizes hydrogen measured in samples obtained with the Post Accident Sampling System (PASS) and containment hydrogen analyzers.
The measured hydrogen is related to the amount of fuel clad oxidation. Clad oxidation is in turn related to cladding failure which is expressed in terms of the percent of fuel rods which are ruptured and the percent which are embrittled. The resulting observation of damage is described by one or more of the seven categories of core damage in Table 2, Cladding Damage Characteristics, in Attachment 1.
- 2.
Definitions A.
Clad Rupture Clad rupture is defined as a break in the fuel rod clad at least sufficient to release the internal gas pressure.
B.
Clad Embrittlement At temperatures above the rupture temperature, significant oxidation of the clad occurs. If the oxidation exceeds the embrittlement threshold, fragmentation of embrittled clad may subsequently occur from thermal shock or hydraulic pressure forces such that the structure of the fuel assembly is destroyed and substantial fuel pellet fragments are released to the coolant.
- 3.
Precautions and Limitations A.
The assessment of core damage obtained by using this methodology is only an estimate. The techniques employed in this section are only accurate to locate the core condition within one or more of the seven categories of core damage in Table 2, Cladding Damage Characteristics, in Attachment 1.
B.
The methodology in this section is applicable under conditions for which there are no voids measurable by the Reactor Vessel Level Monitoring System (RVLMS).

Hydrogen Generated by Radiolysis NOTE
- 1.
The hydrogen generated by radiolysis is a function of operating power and decay time.
- 2.
For the case in which the operating power is constant or has not changed by more than +/-1_0 percent for a period greater than 30 days, that power is used.
- 3.
For the case in which the power has not remained constant during the 30 days prior to the reactor trip, Engineering judgement is used to determine the most representative power level.
- 1.
The following guidelines should be considered in the determination:
- a. The average power during the 30 day time period is NOT necessarily the most representative value for determining radiolysis by fission products.
- b.
The last power levels at which the reactor operated should weigh more heavily in the judgement than the earlier levels.
- c.
Continued operation for an extended period should weigh more heavily in the judgement than brief transient levels.
- d.
For the case in which the reactor has produced power for less than 30 days, this methodology may be employed. However, the estimate of hydrogen from radiolysis will be too high and the calculated hydrogen by core oxidation will be too low.
Hence, an under-prediction of core damage may result.

- 1.
Purpose This section provides a method under post-accident plant conditions to determine the type and degree of reactor core damage which may have occurred by using fission product isotopes measured in samples obtained from the Post-Accident Sampling System (PASS). There are three factors considered in this section which are related to the specific activity of the samples. These are (1) the identity of those isotopes which are released from the core, (2) the respective ratios of the specific activity of those isotopes, and (3) the percent of the source inventory at the time of the accident which is observed to be present in the samples. The resulting observation of core damage is described by one or more of the ten categories of fuel damage in Table 1 in Attachment 1.
- 2.
Definitions A.
Fuel Damage For the purpose of this methodology, fuel damage is defined as a progressive failure of the material boundary to prevent the release of radioactive fission products into the Reactor Coolant, starting with a penetration in the zircaloy cladding.
B.
Source Inventory The source inventory is the total quantity of fission products expressed in Curies of each isotope present in either source, the fuel pellets or the fuel rod gas gap.
- 3.
Precautions and Limitations A.
The methodology in this section relies upon samples taken from multiple locations inside the containment building to determine the total quantity of fission products available for release to the environment.
The amount of fission products present at each sample location may be changing rapidly due to transient plant conditions. Therefore, it is recommended that the samples should be obtained within a minimum time period and if possible, under stabilized plant conditions. Samples obtained during rapidly changing plant conditions should not be weighed heavily into the assessment of core damage.

Precautions and Limitations (continued)
B.
A number of factors influence the reliability of the chemistry samples upon which this section is based. Reliability is influenced by the ability to obtain representative samples due to incomplete mixing of the fluids, and equipment limitations.
The accuracy achieved in the radiological analyses are also influenced by a number of factors. The equipment employed in the analysis may be subjected to high levels of radiation exposure over extended periods of time. Chemists are recommended to exercise considerable caution to minimize the spread of radioactive materials. Samples have the potential of being contaminated by numerous sources. Cooling or reactions may take place in the long sample lines. Therefore, the results obtained may not be representative of plant conditions. To minimize these effects, multiple samples should be obtained over an extended time period from each location.
- 4.
Instructions A.
Obtain and record the plant indications and source of indication requested on Data Sheet 8-1, Input Parameters. Because of transient conditions, the values should be recorded as close as possible to the time at which the radiological samples are obtained.
- 1.
Request sampling at the locations recommended for core damage assessment using the guidelines provided in Table 8-1, Sample Locations Recommended for Core Damage Assessment.
- 2.
Obtain results of sampling and analysis and record the required sample data, corrected to Standard Temperature and Pressure (STP), and time of sample collection on Data Sheet 8-1, Input Parameters. All of the isotopes listed in Data Sheet 8-1, Input Parameters, may not be observed in the sample.
B.
Correct the sample specific activity at STP for decay back to the time of reactor trip following the instruction on Data Sheet 8-2, Record of Measured Specific Activity (Decay Corrected).

Instructions (continued)
C.
Identification of the Fission Product Release Source
- 1.
Calculate the ratios for each noble gas and iodine isotope using the specific activities obtained in Step 4. Record these ratios on Data Sheet 8-3, Record of Fission Product Release Source Identification.
- 2.
Determine the source of release (gas gap or fuel pellet) by comparing the results obtained in Step 4.C.1 to the predicted ratios provided in Data Sheet 8-3, Record of Fission Product Release Source Identification. An accurate comparison is not anticipated.
Within the accuracy of this methodology, it is appropriate to select as the source of release, that ratio which is closest to the value obtained in Step 4.C.1.
D.
Quantitative Release Assessment
- 1.
Calculate the total quantity of fission products found in the RCS per the instructions on Data Sheet 8-4, Quantitative Release Assessment Worksheet.
- 2.
Calculate the quantity of fission products found in the containment building sump per the instructions on Data Sheet 8-4, Quantitative Release Assessment Worksheet.
- 3.
Calculate the quantity of fission products found in the containment building atmosphere per the instructions on Data Sheet 8-4, Quantitative Release Assessment Worksheet.
- 4. The total quantity of fission products available for release to the environment is equal to the sum of the values obtained from each sample location (liquid and gas) as recorded on Data Sheet 8-5, Record of Core Release Inventory.

Instructions (continued)
E.
Plant Power Correction The quantitative release of the fission products is expressed as the percent of the source inventory at the time of the accident. The equilibrium source inventories are to be corrected for plant power history.
- 1. Steady State Power Correction To correct the source inventory for the case in which plant power level has remained constant for a period greater than four radioactive half-lives, complete Data Sheet 8-6, Record of Transient Power Correction. Half-lives are included in Data Sheet 8-2, Record of Measured Specific Activity (Decay Corrected).
- 2.
Transient Power Correction To correct the source inventory for the case in which plant power level has not remained constant prior to reactor trip, follow the instructions of Data Sheet 8-7, Record of Transient Power Correction, where the transient Power Correction Factor is defined as:
PCF 1
,Pj (1-e-tj) e-t 100 Where P, = Steady reactor power in time period j tj= duration of time period j (sec) t=
time from reactor trip to end of time period j (sec)

Instructions (continued)
F.
Comparison of Measured Data with Source Inventory The total quantity of fission products available for release to the environment obtained in Step 4.D.4, Data Sheet 8-5, Record of Core Release Inventory, is compared to the source inventory corrected for plant power history obtained in Step 4.E, Data Sheet 8-6, Record of Steady State Power Correction, or 8-7, Record of Transient Power Correction. This comparison is made by dividing the total quantity available for release by the power corrected source inventory. Record this percentage on Data Sheet 8-8, Record of Percent Release.
G.
Conclusion The conclusion on core damage is made using the three parameters developed above. These are:
- 1.
Identification of the fission product isotopes which most characterize a given sample, Step 4.A, Data Sheet 8-1, Input Parameters.
- 2.
Identification of the source of the release, Step 4.C, Data Sheet 8-3, Record of Fission Product Release Source Identification.
- 3.
Quantity of fission product available for release to the environment expressed as a percent of source inventory, Step 4.F, Data Sheet 8-8, Record of Percent Release.
Knowledgeable judgement is used to compare the above three parameters to the definitions of the ten NRC Categories of Fuel Damage found in Table 1, Characteristic Isotopes, in Attachment 1. Core damage is not anticipated to take place uniformly. Therefore, when evaluating the three parameters listed above, the methodology in this section is anticipated to yield a combination of one or more of the ten categories defined in Table 1, Characteristic Isotopes, in Attachment 1. These categories will exist simultaneously.
