TABLE NOTATIONS

1. Until, the specific activity of the Reactor Coolant System is restored within its limits.

• Sample to be taken after a minimum of 2 EFPD and 20 days of POWER OPERATION have elapsed since reactor was last suberitical for 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> or longer.

• • A gross radioactivity analysis shall consist of tfw. quantitative measurement of the tots 1 specific activity of the reactor coolant except for radionuclides

-with half-lives less than 10 minutes and all radiciodines. The total specific activity shall be m the angassut beta-gamma activity N in the sample within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> after the sample is taken and extrapolated back to when the sample was taken. Deter-mination of t,he contributors to the gross specific activity shall be based upon those energy peaks identifiable with ,a 95% confidence level. The latest available data may be used for pure beta-emitting radionuclides.

• • • A radiochemical analysis for E shall consist of the quan'titative measurement l of the specific activity for each radionuclide, except for radionuclides witn ,

half-lives less than 10 minutes and all radioiodines, which is identified in 1 the reactor coolant. The specific activities fgr these individual radio- i

( nuclides shall be used in the determinatian of_E for the reactor coolant sample. Determination of the contributors to E shall be based upon those energy peaks identifiable with a 95% confidence level.
