iron-55 (Fe-55), strontium-89 (Sr-89), and strontium-90 (Sr-90) are the DTM nuclides of concern. These nuclides are regarded as difficult to measure because they decay by weak beta emission and cannot be detected using routine gamma spectroscopy techniques. Tritium can be analyzed on site using liquid scintillation techniques; iron and strontium analyses require chemical separations that are beyond the reasonable capabilities of the on-site laboratory. In order to estimate the activity of the iron and strontium, scaling factors were derived as follows:

These nuclides are regarded as difficult to measure because they decay by weak beta emission and cannot be detected using routine gamma spectroscopy techniques. Tritium can be analyzed on site using liquid scintillation techniques; iron and strontium analyses require chemical separations that are beyond the reasonable capabilities of the on-site laboratory. In order to estimate the activity of the iron and strontium, scaling factors were derived as follows:
* Fe Because liquid radwaste discharges are processed in the same manner as water processed for return to the Condensate Storage Tank (CST), Fe-55 concentration can be estimated using the scaling factor determined per CY-DR-120-600, Liquid Radwaste Scaling Factors. This method uses the average log value of actual river discharge Fe-55 analyses to determine the scaling factor in relation to Co-60. The current value, calculated on 6-17-04, is 2.68; this means for every curie of Co-60 activity present, an estimated 2.68 curies of Fe-55 is present.

The current value, calculated on 6-17-04, is 2.68; this means for every curie of Co-60 activity present, an estimated 2.68 curies of Fe-55 is present.
* Sr No Sr-90 activity was detected in liquid radwaste discharges for the past two years, so the IOCFR61 Sr-90 scaling factor (the highest IOCFR61 scaling factor available) per RP-DR-605, Waste Stream Sampling and Analysis, was used. This procedure also uses average log calculation methodology. The current value, calculated on 6-29-04, is 2.33E-03; this means for every curie of Co-60 activity present, an estimated 0.00233 curies of Sr-90 is present.

    . Sr No Sr-89 activity was detected in liquid radwaste discharges for the past two years, and Sr-89 scaling factors are not required by 10CFR61. Sr-89 and Sr-90 are fission products that exist in the reactor coolant in a ratio of 1.OE-04 4iCi/g Sr-89 to 7.OE-06 piCi/g Sr-90 per ANSIIANS-18.1-1999, Radioactive Source Term for Normal Operation of Light Water Reactors. Because both are isotopes of the same element, both isotopes will react chemically in the same manner, having the same removal processes and maintaining the same approximate ratio if decay is neglected. Neglecting the effects of decay is conservative for the determination of Sr-89, which has a significantly shorter half-life (50.52 days) than Sr-90 (28.78 years). For every curie of Sr-90 present, an estimated 14.29 curies of Sr-89 is present.

To determine the dose to the public as a result of a liquid release of tritium to the environment, estimates were performed using the current ODCM methodology using the activities calculated above, again assuming a constant 2.0 gpm leak rate and no removal due to decay or the filtering effects of the soil. The dose was attributed to a continuous release from Unit 3 in December of 2004, which does not affect the calculated annual dose or critical organ. Resultant doses (in mrem) and most the conservative receptor is:

The calculated doses are well below all regulatory limits. Assuming a constant release rate, the annual whole body dose limit of less than or equal to 6 mrem to the whole body and 20 mrem to any organ per year are the most restrictive ODCM limits in this scenario. The dose to the public from the release of a 2.0 gpm CST leak DTM nuclides is several orders of magnitude below these limits.

Subject:

Estimates of off-site doses from difficult-to-measure nuclides

Reference:

Dresden Off-site Dose Calculation Manual (ODCM)

Enclosure:

(1) Unit 3 2004 dose projection including H-3, Fe-59, Sr-89, Sr-90 (2) Unit 3 December 2004 dose projection including H-3, Fe-59, Sr-89, Sr-90 On the recommendation of Exelon Corporate Environmental, the impact to dose received by the public from difficult to measure (DTM) nuclides as a result of the underground pipe leak was evaluated. Tritium (H-3),

iron-55 (Fe-55), strontium-89 (Sr-89), and strontium-90 (Sr-90) are the DTM nuclides of concern. These nuclides are regarded as difficult to measure because they decay by weak beta emission and cannot be detected using routine gamma spectroscopy techniques. Tritium can be analyzed on site using liquid scintillation techniques; iron and strontium analyses require chemical separations that are beyond the reasonable capabilities of the on-site laboratory. In order to estimate the activity of the iron and strontium, scaling factors were derived as follows:

  • Fe Because liquid radwaste discharges are processed in the same manner as water processed for return to the Condensate Storage Tank (CST), Fe-55 concentration can be estimated using the scaling factor determined per CY-DR-120-600, Liquid Radwaste Scaling Factors. This method uses the average log value of actual river discharge Fe-55 analyses to determine the scaling factor in relation to Co-60. The current value, calculated on 6-17-04, is 2.68; this means for every curie of Co-60 activity present, an estimated 2.68 curies of Fe-55 is present.

Sr No Sr-90 activity was detected in liquid radwaste discharges for the past two years, so the IOCFR61 Sr-90 scaling factor (the highest IOCFR61 scaling factor available) per RP-DR-605, Waste Stream Sampling and Analysis, was used. This procedure also uses average log calculation methodology. The current value, calculated on 6-29-04, is 2.33E-03; this means for every curie of Co-60 activity present, an estimated 0.00233 curies of Sr-90 is present.

Sr No Sr-89 activity was detected in liquid radwaste discharges for the past two years, and Sr-89 scaling factors are not required by 10CFR61. Sr-89 and Sr-90 are fission products that exist in the reactor coolant in a ratio of 1.OE-04 4iCi/g Sr-89 to 7.OE-06 piCi/g Sr-90 per ANSIIANS-18.1-1999, Radioactive Source Term for Normal Operation of Light Water Reactors. Because both are isotopes of the same element, both isotopes will react chemically in the same manner, having the same removal processes and maintaining the same approximate ratio if decay is neglected. Neglecting the effects of decay is conservative for the determination of Sr-89, which has a significantly shorter half-life (50.52 days) than Sr-90 (28.78 years). For every curie of Sr-90 present, an estimated 14.29 curies of Sr-89 is present.

H The tritium concentration used for these calculations is from the 9-3-04 analysis of the CST.

Tritium analysis of the CST is not performed on a routine basis. The result was 8.624E+06 pCi/L. It s

5 4 b All of the above concentrations for Fe-55, Sr-89, and Sr-90 before dilution of natural sources, which are calculated in a very conservative manner (i.e., higher than anticipated results), are below the EPA derived limits for drinking water (which are 2000, 20, and 8 pCi/L, respectively) as well as 10CFR20, Appendix B, Table 2, Column 2 limits (which are less restrictive). The highest tritium concentration seen at the storm drains prior to release to the plant's canals was 99,000 pCitL in DSP-132 on 9-3-04, which is also below 10CFR20 limits. The canals are not a potential drinking water supply.

To determine the dose to the public as a result of a liquid release of tritium to the environment, estimates were performed using the current ODCM methodology using the activities calculated above, again assuming a constant 2.0 gpm leak rate and no removal due to decay or the filtering effects of the soil. The dose was attributed to a continuous release from Unit 3 in December of 2004, which does not affect the calculated annual dose or critical organ. Resultant doses (in mrem) and most the conservative receptor is:

Whole body 2.17E-4 Child Organ 2.18E-4 Child Critical organ Liver The following are the limits on dose from liquid effluents from Chapter 12.3.A.2 of the ODCM:

1.

Less than or equal to 10 mrem to any organ during any calendar quarter.

2.

Less than or equal to 20 mrem to any organ during any calendar year.

3.

Less than or equal to 3 mrem to whole body during any calendar quarter..

4.

Less than or equal to 6 mrem to whole body during any calendar year.

The calculated doses are well below all regulatory limits. Assuming a constant release rate, the annual whole body dose limit of less than or equal to 6 mrem to the whole body and 20 mrem to any organ per year are the most restrictive ODCM limits in this scenario. The dose to the public from the release of a 2.0 gpm CST leak DTM nuclides is several orders of magnitude below these limits.
