TABLE NOTATION b- The principal gamma emitters for which the'LLD specification applies exclusivily are~the following radionuclides: Kr-87, Kr-88, Xe-133,

, Xe-133m, Xe-135, and Xe-138 for gaseous emissions and Mn-54, Fe-59,.

l Co-58, Co-60, Zn-65, Mo-99, Cs-134, Cs-137, Co-141 and Ce-144 for

! particulate emissions. This list does not mean that only these nuclides l

are to be considered. Other gamma peaks that are identifiable, together-with those of the above nuclides, shall also be analyzed and reported in the Annual Radioactive Effluent Release Report pursuant to Specification l 6.9.1.8.

3 factor of/3 and (2)f4he condenseyoffgas nobja gas activity nitor shows that offgas activity has not increased by more than a factor of 3.

d- Tritium grab samples shall be taken at least once per 7 days from the ventilation exhaust from the spent fuel pool area, whenever spent fuel is >

in the spent fuel pool. l e- The ratio of the sample flow rate to the sampled stream flow rate shall ~'

be known for the time period covered by each dose or dose rate calculation made in accordance with Specifications 3.11.2.1, 3.11.2.2 and 3.11.2.3.

f- Samples shall be changed at least once per 7 days, 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 /> after changing or after removal from sampler.

Sampling shall also be performed at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for the main i plant exhaust for at least 7 days following each shutdown, startup or j THERMAL POWER change exceeding 15 percent of RATED THERMAL POWER in one l hour, 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 /> of changing.

This requirement does not apply if (1) analysis shows that the DOSE EQUIVALENT I-131 concentration in the primary coolant has not increased more than a factor of 3; and (2) the condenser offgas noble gas monitor shows that offgas activity has not increased more than a factor of 3. 1 l
