RADIOACTIVE GASEOUS WASTE SAMPLING AND ANALYSIS PROGRAM TKbl2 NotItient

a. Lower Limit of Detection is defined in table notation (a) . of Table 4.16.1-1, specification 4.16.1.

b. For certain radionuclides with low-gamma yield or low energies, or for certain radionuclide mixtures, it may not be possible to measure radionuclides in concentrations near the Lower Limit of Detection. Under these circumstances, the Lower Limit of Detection may be increased inversely proportional to the magnitude of the g amma yield (i.e. , 1 x 10-4/I, where I = photon abundance expressed as a decimal fraction), but in no case shall the Lower Limit of Detection, as calculated in this manner for a specific radionuclide, be greater than 10 percent of the Maximum Permissible Concentration value specified in 10 CRF 20, Appendix B, Table II (column 1).

c. Sampling and analyses for principal gamma emitters shall l also be performed following shutdown, startup, or a THERMAL POWER change exceeding 15 percent of the RATED THERMAL POWER within a 1-hour period if analysis shows that the DOSE EQUIVALENT I-131 concentration in the primary coolant and the Main Stack Noble Gas Activity Monitor reading have increased more than a factor of 3.

Sampling shall be performed weekly, and analyses shall be completed within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> af ter changing (or af ter removal from sampler).

The more frequent sampling and analysis requirement applies only if analysis shows that the DOSE EQUIVALENT I-131 concentration in the primary coolant and the Main Stack Noble Gas Activity Monitor Reading have increased more than a factor of 3.

e. The ratio of the sample flowrate to the sampled stream flowrate shall be know for the time period covered by each dose or dose rate calculation made in accordance with Specification 3.15.2.1, 3.15.2.2, and 3.15.2.3.

f. The principal gamma emitters for which the Lower Limit of Detection specification will apply are exclusively the following radionuclides: Kr-87, Kr-88, Xe-133, Xe-133m, Xe-135. and Xe-138 for gaseous emissions; and Mn-54, Fe-59, Co-50, Co-60, 2n-65, Mo-99, Cs-134, Cs-137, Ce-141 and Ce-144 for particulate emissions.

This list does not mean that only these nuclides are to be detected and reported. Other measurable and identifiable peaks, together with the above nuclides, shall also be identified and reported.
